Hey guys,
I just got my phone two days ago, but currently my Galaxy S2 just barely makes up 1 day with moderate use. (so no gaming, watching youtube or GPS)
I've been searching for an extended battery to prolong the current use of my phone on one charge, and I found these two options.
Has anyone tried one of these battery's:

http://www.dealextreme.com/p/replac...h-back-case-for-samsung-i9100-galaxy-s2-67304
I know someone who purchases stuff from this website regularly so I'm not questioning the safety of the website, only the quality of the battery. And I know its makes the phone thinker, but that's fine for me.
Btw, I've read also the alternative solutions about putting a ROM on the phone, but I'm not good at that so I'd rather get an extended battery.
Though, I'm not sure how safe non-orginal batteries are from Asia.
Anyone have any experience with that? And is there a risk for the phone, or is the only risk that the battery will just suck?
I've previously read these threads about extended batteries:

Thanks for your advice!

The only non official battery I would get is Mugen. Or the samsung one.
The Anker ones get 'ok' reviews but there is hardly any proof your better off than stock (although You do get two of them... so that is going to be double the running time).
Have you not tried checking your settings, making sure you dont have any known terrible battery life apps etc etc etc?
When I first got my SGS2 I could run for 24hours straight easily on Wifi most of the time and loads of texts.
I now have around 65% left before bed so no idea what battery life would be like now. but I know you said you dont want to change roms/underclock etc...
I plan on getting the Samsung 2000mAh one when i get bored though.
I was gonna say the same thing- Mugen Power or official ones. Batteries are one thing you do NOT want to bootleg for a plethora of reasons.
Mugan and Seidio batteries are just as bad as the no name brands. They are like Monster Cable, in otherwords ALL BS marketing! www.batteryboss.org has tests. OEM batteries are the best if they make a extended battery or any cheap thing on the net will do, Since they are so cheap you can get double or triple the number of batteries for what you pay for one brand name one
I heard one saying" the man who uses smartphone is a good man, because he must go home and charge the mobile phone every night"
i bought several batteries from here.

Alright, so what settings in particular would you check? I have GPS always turned off, except when I really use the navigation. Screen brightness lowest. Overall I just have the basic apps Office apps, Dropbox, Skype etc. I know there are several apps to "tweak" the phone, but I haven't had time to dig into the whole thing. What ROM do you use, and what tweaking apps? CynoginMod or something? Any quick short tips?
Moreover, I like the functionalities of the basic ROM, and don't know how to put on any different ROM yet, including what the advantages/disadvantages will be.
Though, I love the phone as it is at the moment. Just the battery life is not that great.

I checked the website batteryboss, but it only seems to show tests of old phone models. But is there a certain risk with "bad-quality" batteries, or is the only risk the costs of buying them?

Nice try Luis2012. I'm not surprised you say you got the best service, as it seems you are either the owner or the promoter of that website.
Or is it a coincidence that virtually every single post out of all 19 posts, you recommend a product from that wesbite?
Moreover, I assume both websites "papadigitals, and "digglove", are yours, since they have identical layout and you both promote them as being a satisfied "customer" in virtually every post of yours.
I will keep updating this Google spreadsheet as we go. I'm the only one that can edit it for now, but I'm willing to add contributions from others, just email me. If you wish to do a few of them, I'll give you edit rights. I'd make it fully public, but every time I've seen someone try that, they spend more time reverting vandalism from random children on the net than updating it.

There's only one battery in there right now, the Hyperion 3500, but I'll be adding more as I get them. I'll also be testing the stock GSM 1750. I'm re-testing the Hyperion now and I will keep the doc updated with the latest/averages. The next battery purchase I make will likely be the Samsung 2000 mAH, just to compare.
Testing method:
I'm using an R/C battery charger/discharger for the testing. It measures true battery capacity on charge and discharge. For discharge, I set the voltage cutoff to 2.9V (2900mv) which is the safe zero point for a single-cell lipo. I'll report averages when multiple tests are performed. I will also be evaluating the effect of various discharge rates, currently I'm testing at 1A discharge. For extended batteries, 1A is well below .5C, this is well within range. The next Hyperion test will be at .5A just to see if it makes a difference.
What will NOT be reported on this spreadsheet is anecdotal evidence like "ran my phone for 12 hours with screen on for 2.5". I am interested in real data across a known load. There are plenty of stories on here now, there's no point in restating them.
What about <random ebay battery>???:
You have a couple options. You can send me one for testing, which I will return to you at your option (I'll pay for return shipping), or you can set up a tester of your own and report data to be included in the list. I don't have unlimited money to spend testing batteries. That's also why I won't be testing Mugen/Sedio batteries unless someone sends me one. They cost too much. Though if someone has the offer for a $20 NFC upgrade from Sedio, I will cover that cost if you send me the non-NFC battery for testing.
I think your method sucks:
Well, that's your right. If you think you have a better one, post. I'm willing to listen. Know this though, I've tested this setup against known batteries and get consistent results. If you don't have data to back up your claims, I probably won't change my mind.
What about "reserve capacity" (below 2.9V):
Discharging below 2.9V will damage the battery cells. I have no interest in doing that. Cell phone batteries include a protection circuit that would likely prevent discharge much below this level anyway. If a user can't actually USE the capacity, it's irrelevant to the user. If I have to destroy the battery cell to get at the capacity, it's not really there. Unless what you are selling is a single use battery?
Why should I care? It's still a good deal:
Perhaps you don't. But consider this, if they lied about capacity, what else might they lie about? Perhaps they used the cheapest cells they could find, so you only get tens of cycles instead of hundreds. Perhaps there are other problems. Perhaps not. I also take issue with made-up numbers being used to sell products. It's no different than advertising 1 gallon of milk, then only giving the customer 75% of that. It's not acceptable with other products, why should it be acceptable for batteries? The OEM cells test out fine, I see no reason aftermarket batteries should be held to a lower standard. Particularly for those that cost significantly more than OEM batteries.
License: Anyone is welcome to repost the data anywhere. I do ask that you link to this post though, just so that any other data reports can be added.
Updated with the stock battery. As expected, it performs a little above the rating. All the Samsung OEM batteries I've seen tested do what they say they do. The second test on the Hyperion pushed up the capacity a bit as well. To call it a 3000Mah is about as generous as I can be. For the price, not bad, but still irritating. And hopefully capacity doesn't fall to nothing over time. NFC would be nice as well. I see they released an extended for the LTE version that has it, hopefully the GSM version will get updated as well.
Good thread.....yea, would be really interesting how well the 3rd party batteries hold their charge over time compared to stock.
I've heard Mugen/Seidio batteries can't hold their original capacity very well over time and then they're terrible.
So as it seems the underlying issue was all in these batteries of note7 and the aggressive design of the phone chassis itself - leaving little to no gaps for battery, probably not enough space for battery front and back either so batteries easily got squashed inside of the super-slim factor phone design chassis while wearing phone in tight pocket like situations and due to the fragile nature of the battery it just got affected, damaged and caught on fire like explained in latest samsung reports.
Here is the deal, I will get equivalent original samsung battery from S7Edge model etc, same 3600mAh capacity (providing the thickness is same or less than that of Note7) and with necessary modification (if applicable) to the battery terminal flex connector so it clips right in to the Note7 PCB just like original Note7 battery did, I think this should be excellent workaround for dangerous Note7 batteries!
I of course would try to perform various tests before final assembly of the phone with new battery mod in it, such as full discharge and recharge, also recharge while heavily loading phone with benchmarks, and also attempt multiple fast charging routines monitor how phone behaves with the new battery, that is - all these tests are to be done on phone fully disassembled in the worst case scenario if phone battery still would get caught on fire during the testing I would at least salvage the phone from disaster that otherwise would be inevitable when testing phone fully assembled.
Your thoughts?
I would say you should give it a go. But isn't the S7 battery bigger ? How about trying to go with the S7 non edge battery instead ? Plus I thought that some battery were not soldered properly and made a short circuit to happen ?
Source I read : https://www.cnet.com/news/samsung-galaxy-note-7-return-exchange-faq/
Im yet to find out about the battery dimensions/size. while s7edge appears ~1mm thinner to my observation makes me think battery design should be similar or lesser in thickness and I really expect it to be no taller/wider but that is to be confirmed later when I take it apart(if it comes to that).
If batteries do fit, all I need to do is to unwrap the shield of the note7 battery where PCB is soldered to +/- terminals and replace battery connection pcb the same way back to s7e battery.
I think s7e battery would be the best candidate as for 3600mah capacity vs 3500mah note7 capacity, even if phone some way tries to charge this battery further than 3500mah as per physical capacity of the battery it should be "safe" I think.
Where if the battery installed would be ~3000mah etc, note7 battery terminal PCB chip would probably try to achieve 3500mah capacity and charge may again result in innevitable fatality, that is unless note7 battery pcb chip registers battery capacity 3000mah as wear and tear and adopts to charge only to 3000mah without actually overcharging it.
Had some hobby experience playing with iphone 4 4s 5s batteries in the past where I would swap around pcbs with batteries and phone would work, not ideal because I didnt pay much attention which went where but it did work to great extent.
I too see that the defects ratio was not definite and more so it was one in many many thousands that had bad soldering or manufacturing practice etc missing protective layers and so on, as I observe my note7 battery is always very cold never hot even cooler than that of s7 edge so I think analogy goes to be correct, but still I rather not take much chance with it if you know where Im going with this - "WHAT IF..."

Well, whatsup with that straight "face to the wall" so well thought trough pessimistic comment?
Do you not have life to live meantime?
It seems as if the flex cables are different and the note 7 battery is narrower.
I'm disappointed there hasn't been an aftermarket manufacturer that has created a "safe" battery replacement yet.
I'm using a Verizon Note 7 that I reflashed with AT&T firmware. Since the IMEI is not an AT&T IMEI, I haven't had to worry about "green battery" or "killswitch" updates coming to the phone. Still worried daily that my house will burn down or something, however.
I think no company will provide an aftermarket battery because the market is very small. That eventually would happen if Samsung refurbished all Note7's and reintroduced them in the market. Mine (have 2) are working flawlessly without any issues
Sent from my SM-N930F using XDA-Developers Legacy app
Im not certain about sizes yet, it could be alot due to optical ilusion, as s7e and n7 are little different layout, etc - battery in the s7e is seated little further to the left (meaning more toward the center of the phone) and the camera on s7e at least to me from the first glance when compared to n7 looks more further to the right side which creates illusion of s7 battery to be wider because of its positioning. I may be completely wrong, just wanted to throw that in there though.
Also, battery from note4, S5 can potentially be used too, of course its core would need to be stripped and de-soldered from the old PCB and after that you have a naked battery pack that is still permanently safely sealed with two (positive and negative) terminals exposed ready for soldering with original note7 battery PCB and connection, providing we get enough room inside battery compartment. it all can be utilized, and even more, maybe note5, maybe s6 s6edge s6edge+ s7 and other similar sized samsung batteries of recent production years have similar measures that will make it a good potential donor? I'd say even if one can find battery of similar but not larger in size and capacity battery from any other manufacturer it should also work by the same methods of DIY, of course obviously acknowledging that the use of quick/fast-charge can be detrimental suicidal step in a way of charging the phone after any such DIY, even if it was samsung approved battery, fast charge is a fast-lane of premature battery wear/overheat and failure, such as explosions.
Here is my observations, I own few of these Note7. I have never ever once used fast charging on them knowing what it does and how it physically affects batteries, never ever had I used it on my note5 s6 s6e or s7e, I rather have my phone charge longer rather than let battery prematurely wear out sooner, and nobody knows what if S6 S7 batteries undergo the same quality testing like note7 batteries did and it was just a great matter of luck to a slight degree that not so many s6 s7's had exploded in the past due to quick charge technology used. Of course, alot of what I said is speculation, but just take that for a minute and let it sink in, think about it. Its certain - not everything that ever happens is publicized.
Ok, according to my research (call it bro-science) as it was internet based on official reported measurements of devices, I picked some stripped down samsung phones (notes and S series), adjusted these pics to represent real manufacturer reported dimensions in photoshop and measured batteries in the pictures. So far I can give rough estimates and the best to my knowledge these measures may not represent exact measures of the batteries but actual measures should be less or equal than what I have figured out. Only thing left to question is the thickness of the batteries:
We have here a patient, in a name of: Note7, this battery measures 99mm x 38.5mm
Other models I have looked at were:
S7edge 96mm x 41mm ( @MrBaltazar > you were correct regarding battery size there, its too wide )
S7 88mm x 37.5mm (looks like ideal candidate for now, especially providing extra headroom for DIY work on the top of the battery which may not come out as neat as from manufacturer)
S6 99.5mm x 46mm (too tall & too wide)
Note5 108mm x 42mm (too tall & too wide)
Note4 93mm x 39mm x 5.5mm(also seems like an ideal candidate plus its 220mah more in capacity vs S7 3000mah battery)
S7 Active 91mm x 40mm (this would be interesting @ 4000mAh ... I just am almost certain - thickness of this battery got to be greater than note7 or note4/s7 candidate battery... a strong guess)
I feel note4 may be real good choice if S7 battery thickness is more than that of Note7, and note4 battery turns out to be slimmer or the same thickness after being stripped as Note7 battery ... especially after removing the top plastic trim that holds gold plated battery terminals with battery pcb and unwrapping first layer of label with NFC antena, that should shave off additional ~0.2-0.5mm from the whole 5.5mm note4 battery thickness.
So thats that, some food for thought
Alright first off,
HOLY ****ING ****
Second off,
That's amazing
Third off,
**** you ;P
Keep up the good work mate! If you can find a system you can replicate let me know, I would LOVE to try it.
Im sure it will all work well, keep an eye out here, this actually drives me somewhat to do this. Most interesting is testing under load once all is done.
I was thinking more, and I believe S7 3000mAh battery is the best choice regardless of anything (unless S7 Active battery magically fits just the same, but its unlikely given its huge capacity it must be much thicker, but I am not sure 100% yet anyway). S7 and Note7 is of the same period/same production line, so if anything it should work the best, even with quick/fast charge when needed, as I thought today it still would be a very good feature to use if one is stuck in an emergency situation such as airport and needs a quick sufficient charge in short time - if fast charge works well - its there to use, otherwise I would still be against using it every-time, for longevity of course.
another interesting trick would be to remove Note7 battery and have it X-Rayed to see if any dangers are underlying like those explained by samsung, should be visible under high-res x-ray imaging, but I dont have access to that(yet) so I will still keep the note7 battery cell for a while until maybe I get access to such equipment.

Sounds like the Note 4 battery might be the ticket. I'd be willing to try this out if I knew how to attach the note 7 flex cable to the note 4 battery, as well as disassemble both batteries.

Please keep us informed on your endeavors into battery exploration.
---------- Post added at 10:12 AM ---------- Previous post was at 10:07 AM ----------
I am actually almost tempted to order a s7 battery and see if the connection is the same on the note 7 PCB. Then it's just a matter of bending the flex cable into place
Connectors all look identical for S6 Note5 S7 S7E , what worries me most I think the most is its the way pinouts can vary on them model to model, as I remember there's not only Positive/negative terminals , look here:
other connections are also important, and most important that it is not going to get connected in reverse which I dont want to even try, thats too precious loss if I fry anything on note7 pcb, try go and get another one of those note7 pcb's nowadays ahaha, let alone note7's !
So, all in all we can try and measure terminal voltages on both Note7 vs S7 and compare how it looks on multimeter, then try position it accordingly and expect it to be straight fit, then if all works well and flex is actually long enough - solution is found, no need anything to solder I suppose just plug in, bend flex a lil bit where necesary, making sure no sharp edges are exposed to the bent flex, no excessive pressure applied on bent flex cable before/after assembly, and for most part that the battery is right thickness and not squished in there, then its all green-lights and good to go, but just by the visuals it looks that note 7 has somewhat longer flex, and oposite facing angle, look here:
S7:
Note7:
I did not realize it would be this difficult to find authentic original non-replica s7 battery... lots places sell those but if one has half functioning brain its clear as day these are non-original... However, I did find some note4 original in samsung retail packaging and all papers batteries, which I think rather go with, which is almost local too vs. importing another second best from China/Hong Kong... so that's that... My only hopes in buying note4 battery, if its truly original and new unused not charged unabused piece is that if it will still actually hold 3000+ mah capacity off the shelf ... hope it will. I mean after all it would be dormant for 2~3 years or more, and batteries do get old and sometimes just prematurely die also...
Will keep you posted
Night
Updates...
So far I was very unlucky sourcing S7 battery which is my personal preference option due to this battery being most "up to date" tech variant available that should logically fit vs. the second best choice - a Note4 battery...
Also my donor Note7 is due in tomorrow as best case scenario, or latest Monday-Tuesday the 19'th-20'th of February, and I just dont feel like burning 30bucks on battery that probably does not fit by its thickness... (talking about note4 battery) , so I really want to take apart this note7 first and inspect the thickness of its original battery and the depth of the phone. What I mean in detail by that - please review this in-depth detailed report:
https://www.instrumental.ai/blog/2016/12/beyond-the-teardown-galaxy-note-7
^^^ That is allegedly a note7 illustrated right there, this gives me hopes as if I stripped plastic and NFC chip from note4 battery I should end up with just about 5mm of thickness of the naked without NCF chip and w/o labels battery. However, I need to look harder about the S7 battery thickness as my eyesight would be strongly concentrated toward that if it was of the same thickness or even better if it was just under 5mm, but I am not sure...
I also contemplated maybe even retrofitting apple iphone 6/6s or 7 battery providing it fits by its dimension and voltage measures (yea just pulled it from thin air havent measured or researched yet) , but at least talking about voltages should be bout right and capacity may be close to that of S7...
Otherwise I was even thinking removing NFC/Wireless charging mechanisms from the enclosure so the excess pressure from battery wear and tear does not build up on either old original or new replacement retrofit batteries, give or take there has to be ~10% headroom for battery expansion which was really not thought trough in note7's (or if it was there was general battery design fault that was underestimated and exaggerated expectations from engineers who designed battery had failed them prematurely...)
I have meantime located S6 battery which is way too big and it by no means going to be fitted there but I have another few tests in mind until I get my properly fitting battery alternative, just to rule out some questions and variables...
I think Chinese market fellows are up to some news regards note 7 because just lately I have noticed increase spike of note 7 cases and accessories at least on ebay, it just spiked my curiosity, what are the plans of samsung for the remaining 3+million note7's that they got back from the recall, are they by slight chance gonna push Note7S with note8 and S8 release? what are the chances of that happening?
Also I was deeply considering how would note4 battery be of a worse technology build vs S7 battery, knowing everyone who I know had note4 in the past almost every single one of them batteries had expended and died out rather soon within first year or so... I am just very cautious about this happening prematurely while retrofitted in note7 ... where as with S7 as many people I know using them and it has been about a year now of heavy use and abuse including those using quick-charge, batteries still perform ok and not swelling which is more promising when compared to note4 battery.
As lucky as I can get just by doing online hunt, I found one seller on aliexpress selling copy replacement batteries where he claims battery measurements to be ~88mm x 40mm x 5mm, and here we are talking about non original battery that is rated @ 3300mah as per sellers web page , out of which I feel it is reasonable to believe that it holds quality ~2000mah capacity knowing how all these generic batteries are made... it is real hard to find genuine battery, unless if I want to wait 60 days, I can order from China... hard hard decision on waiting vs the availability. I really am leaning forward just straight S7 battery swap with best hopes of longevity , but the quest now is to get exact measurements and fast delivery.
PS: Anybody reading this has new original battery for S7 (SM-G930 / G9300)who can ship it over to me or measure it precisely X * Y * Z ?
Thanks
I Tried Note 5 battery. Its bigger in terms of Length and width. As mentioned before flex cable is different and male/female end of connectors have been interchanged.
Out of desperation disassembled old battery and took the battery circuit out. Soldered Nokia BL-4C 3.7 V 840mah battery. Voltage of battery at full charge ~4.1V. Charging stops at 100%. I was thinking of installing something like old rom to limit charge to 60%. I will be installing wireless charging battery for the battery backup.
Its quite fun to play with it.

Nice post, looks like you did not strip nokia battery from the nokia battery charging PCB so it literally goes two ways. I may be wrong but I believe I am not, when battery wears out on original samsung battery combination, lets say samsung s7 battery was used and abused and from 3000mah drops to ~1700mah real usable capacity, the charging chip adjusts accordingly to the current usable capacity and stops charging when receives signaling from the battery that it no longer increases in the charge capacity. Hope Im putting it out right so you can understand, I believe if you use note7 charging pcb chip on stripped nokia 800mah battery it should literally accept 800mah as total max capacity and record this "100% equivalent" memory record in to its circuit (dont know if its one way memory write though , because as if you were to add 3000mah s7 battery on the later date, the N7 battery charging pcb chip may decide only charge it to 800mah due to previous record of capacity created when 800mah battery was used...)
Its complicated I know... but thats what I would do. Otherwise, two nokia batteries if stripped could be coupled parallel (if it fits well) and you therefore have 1600mah battery) which is rather usable for at least ~ half a day off the power cable
I was also thinking about note7 wireless battery charger mod, I dont know whats inside of that battery back pack, but if there is enough space to store two S7 or S7edge batteries, that would be amazing DIY mod that would deliver ~9000-10000mah of raw juice coupled with S7 battery already installed in the N7 frame.
For most I hope tha note7 battery charging chip does not have memory recording feature on its own, so we can play with random batteries for as long as we find one working the best, as otherwise if it does have such effect - its sad news, as once you install less than 3000mah S7 battery for testing etc, you can never use 3000mah brand new batery to its full capacity, but I am only speculating here for the most part untill its tried.
While on this note - would you have another of the same type nokia battery to connect in parallel (doubling the capacity) to see if it still charges to 100% on indicator and last ~twice as long after this mod?
PS: I think time to time n7 backpack battery cases appear online on ebay for lots cheaper, worth a search there too
Also, the charging indicator @100% is fine and well, and setting limitation of charge to 60% in settings would result in 60% of currently measured capacity which I believe is pretty pointless as that was the aim of samsung safety/prevention methods, knowing batteries usually failed while in higher charge state - they tend to swell more and tight fitment inside the n7 prevents expansion therefore battery will be softly pushing against itself while theres a risk of failure at that shorting within itself due to built up inner pressure, thats why the limiting to 80% then 60% then 30% was put in place so batteries does not reach high charge state there fore does not expand as much within itself and the risks are greatly reduced, that's how I understand samsungs point of view on the issue.
Let me know what do you think

Hey I was just typing a reply to this thread and have seen you reply to it before I clicked [Submit Reply] ...
Ok, so Im in a "triangle" situation here right now... yes I had more of them note7 on hand but now... I have only two coral blue note 7's, one is new and unused but still it is unsealed box unmodified/unupdated unit which works perfect and charges to a 100% battery etc which I intend to keep this way for later on selling it for a profit probably to some enthusiast collectioner guy...and another coral blue note7 is as good as new but it is used for few weeks by the first owner and it had this deadly update from samsung that prevented it from charging, so I have fixed this and now it is charging while still on its latest firmware and I am willing to play a little more with its firmware and so on until I decide to sell it too ... yeah I cant explain, I just enjoy reaching for some "goals", hitting them hard and then letting them go for someone else to enjoy while myself moving on, maybe weird, I know., but stay with me here for a moment. So I was thinking long and hard, and I am unable to justify splitting open my last firmware-fixed note7 that I was so anticipating on doing so ... that waterproof seal from factory means alot to me, I'd rather keep it on the phone for as long as I can, unless that would be inevitable, as I originally imagined the last note7 unit with disabled battery charging would require me to split it open to do at least battery charging up outside the phone just to get it ON so I could work on it trying to patch firmware and do some battery experiments further while Im at it, but as you may know I managed to fix it without opening it... and I few days ago (again...) I ordered myself another one of these bad boys Note7's, but this time its for real guys, its a cheap live demo unit (LDU), it should have no IMEI/no GSM radio chip and otherwise to be identical to retail units, so this is the model I will be stripping apart, most definitely, promise. Meanwhile I am really seriously thinking about learning on rom modding so I can build at least one or few fresh Note7 rom's for folks that are still out there holding on tight and giving all the love and care for their old note7's. The only one real reason is holding me back from keeping and using one of two note7 straight away and modifying it for self use is that I cannot get my hands on any dual sim note7 model (SM-N9300 or SM-N930FD), which I adore to death, literally... as my daily driver of a phone is S7edgde DUOS at the moment and it is a life saver not needing me to carry two phones everywhere I go, and any of note7's I had would make me do just that, use 2nd phone which is really not ideal at all... however dilemma in my mind goes to expect me to finally modify and use one of the two blue note7's if I will not be able to sell it for minimal no-loss profit, but for now I do not the plan on using any of them for daily use, hence my reasoning on waiting till I get Note7 LDU some time next week and give it all my tech-modifying love so I can break the IP68 water sealed back loose, probably crack it or scratch it and not be bothered about the rough love and abuse because Im about to give it, as this LDU has no such value as any of other retail units that I have... hope you's understand where Im coming from and are patient enough not to cross me over yet and wait a little more for my experiments on battery mods.
On another thought, since samsung-pay will not work and I am not sure if android pay will have any use with such heavily modified note7, I was really thinking taking out NFC/Wireless charging modules from the inside of the back of note7 to get more headroom for battery swap, plus if opportunity allows, I may as well split the chassis from the LCD screen later (if its feasible option) and measure the firewall thickness between the amoled screen and battery, see how much more I could machine off of that firewall while keeping some minimal amount of it still there for screen protection purposes, just a thought in an open wild triggered by the last samsung report regarding refurbed note7's which will receive thicker chassis, which may be ~2mm extra in thickness etc...
First of all i know there is a similar post here https://forum.xda-developers.com/go...ent-direct-replacement-battery-nexus-t3905671
i buy the battery because of that post so believe me, im aware of... The battery is a brand new item from a german manufacturer of pollarcell goods (premium battery as they claim to be)
I order it at ebay for GBP 17.90 (US $23.28) but i had a 10 dollars coupon so i just had to pay 13 dollars plus free shipping. It took 9 days germany - argentina so WOW not bad, bad is the postal service here but anyway, after two months local shipping i got the battery; here:

and then i proceed to replace it (u can see i still had an original battery replacement (was excellent but after so long i can only get 3 nice hours of use)
so after all the waiting the battery wasnt working!!!!!!!!!!!!!!!!!!!!! nothing, was like no battery there at all, the bolt was gone as soon as i took the power cord away.
I had two options, send it back (and wait 3 or 4 more months with a battery that exponentially decrease its performance day after day) or open it and see what is going on with a small chance that if nothing is wrong i lose the 13 dollars because the warranty is gone...so guess what
those two metal plates have to make contact with each other so, after fixing that with some tape (i guess u can solder with tin also) now the battery works fine
now i will charge it fully and in a few days i will update with the performance in a regular day and sot test. Thanks
Wow, i have my old Nexus 5 catching dust somewhere in mi home. This could be interesting. Thanks for the info mate. Will follow your updates.
Enviado desde mi SM-G965F mediante Tapatalk
ok first update, 21:41 june 18, disconnected 100%, and last till 22:21 june 19 with 2% remaining, with no signal of sudden drops of charge or else. yes ok i have an app always running 24/7(followers assitant) and thats whay it took 17% and im a big instagram user BUT in constast to that i have another cellphone solely for work so this is my personal phone and is mostly social media and stuff, i will says any user will get simillar performance if you are in stock like me (im running full stock android 6.0.1 with xposed and gravity box) or may be lower performance if u use too much gps i guess. Sorry i cannot give more useful feedback like "what about using custom roms or greenify" .
Thanks, next test will be SoT, regardless of https://www.youtube.com/watch?v=3Zt2j8lFbJQ
I just ordered this battery for my ancient Nexus 5.
I hope I don't screw this up. It's still a neat little device and I want keep it around.

This was an easy swap, watched a video and read some tips ahead of time. Worked out great.
The battery life is acceptable now, and I can easily make it through the day. I don't have any good stats on it, but the difference is very noticeable.
My experience so far...
I've been using this battery for about 2 months now. Battery life is good, better than the 5 year old stock battery I was using before. Well, don't expect any miracles, but at least now the phone can make it through the day without the need for charge, with mild usage. Mine lasts about 22hrs, whereas with the stock one it lasted about 17hrs at best.
The only disadvantage I have found is that it lacks a temperature sensor. Mine always shows a temperature of 28-29C no matter the load, charging or not. However, it works well, and since its price is quite reasonable, that's fine by me!
I've had a previous experience of buying an "original" battery (identical sticker and lettering with the stock), which proved to be a potato wrapped with aluminium foil.... So if someone is looking for a decent replacement for their aging battery, that is easy to swap, I think this is the battery to go for. Big thanks to Polarcell for keeping the hammerhead beast alive!
I bought a very expensive Polarcell (£25) for my Nexus 6. I had no quality problems with it, and even with my QHD screen I rarely drop below 50% battery by end of day with moderate but regular use (emails, texts, Telegram, news, XDA, updates, etc.)
Polarcell seem to provide quality products, so I'm surprised that the OP had a physical failure. Good work getting it fixed.
It's a good upgrade if your battery is dying.
Just another thumbs up for this battery - ordered one after seeing this thread. Thanks so much! It was getting really frustrating with all the fake or useless aftermarket batteries out there that last 5 minutes.
Ha ha ha... I'm genuinely glad you're one of the (IMO) lucky ones. Have a look at this thread.

My Nexus 6 Polarcell is still giving me stellar battery life. If you check out the Polarcell reviews for the Nexus 5 on Amazon UK you'll see that I'm at least the third to get a dud battery. Shame.
Hey guys, I need some help with choosing a battery. After many years with the original battery lately the performace droppes drastically and sometimes when I'm below 35% and I'm taking pictures I experience shutdowns. So I finaly decided that it is time to buy a new battery. After reading here and on reddit I'm wondering if I should order a Polarcell battery. I was going to order a Polarcell one, but then I saw a review on amazon saying that after 2 years it has bloated and lost a lot capacity. While searching for batteries I found another one with good reviews and I'm wondering which one I should get. Your help will be highly appreciated. I need to order from Germany or somewhere in the EU so they can deliver it to my country.
sorry I am a new user and cant post the links directly
PolarCell: amazon. de/cellePhone-PolarCell-Li-Polymer-kompatibel-Google-Polar-Wei%C3%9F/dp/B00VJ8FIV8
Green Cell: amazon. de/Green-Cell-Li-Ion-Zellen-2300mAh/dp/B07JJFXDMV/
I'm also wondering if I order Polarcell, should I order from amazon or ebay?
Having had one great Polarcell for my Nexus 6 and a totally dud one for my Nexus 5, I wouldn't gamble again on getting a good Polarcell. If there are good reviews for Green Cell, I would go for that one.
Why do you guys keep operating on the assumption that replacement batteries for cell phones that came with sealed in batteries (i.e. essentially all phones manufactured for western markets in the last decade, or so) are actually available? I understand that this perverse business model of selling almost exclusively premium-only products that turn into useless paper weights after ~2 years invariably leads to a desperate hope in the purchaser, which makes them more susceptible to fall for scams that profit from desperation, uncertainty, and the magical thinking that makes up the gap (even I, being aware of the simple facts I'm about to point out, nevertheless fell victim to what of course had to be a cell phone replacement battery scam -- because they all are, to varying degrees, scams; I'll elaborate on that below).
Here are some basic facts:
1. The claim that cell phones would be bulkier if they had replaceable battery is an egregious lie. Look up the dimensions of the last western Android device whose battery was replaceable, the LG V20. It was neither any thicker, nor did it come with a battery with substantially lower capacity than its peers at the time.
2. The claim that a replaceable battery limits the functionality of the phone is dubious at best. Around the time the V20 was still produced, the recent fad was "water proof" cell phones. Except, as I recall, they turned out not so water proof after all. "Water proof" in the end turned out to mean little more than "could be splashed with water, like when taking a shower). And if you read all the restrictions in the EULA on where exactly you were allowed to use the phone without losing warranty, the "water resistant" feature in reality was nothing of the sort. I don''t recall any other similar claims regarding other features that would be severely hampered by a removable battery door, so I'll leave it at this.
Now, to get to the availability of batteries: this may come as a surprise, but manufacturing LiPo batteries is not so trivial (in terms of barrier to entry) that you have all these previously unheard-of (in reality, fly-by-night -- and I'll get to that in a bit) companies that magically produce exact replacements for popular phone models. In fact, phone manufacturers rely on two sources for their batteries:
1. In-house: this is the case with Sony/Samsung/LG/etc. They manufacture both the phones and another division makes the batteries.
2. Contracted manufacturers: This was the case for at least the Huawei made Nexus 6P, where the battery maker was a different entity that was contracted by Huawei to produce the batteries they used in the 6P.
-In the first case, the manufacturers make their own batteries -- for phones that aren't expected to have their batteries replaced. For warranty related issues, they simply issue a new phone and program the existing IMEI into it, making it indistinguishable from the failed device. Salaries in every part of the world have risen, even while the cost of producing electronics monotonically fell at the same time. There was a point in the past where the two lines crossed and it became unprofitable to repair devices, rather than simply replace them and throw the defective device in the trash.
-In the second case, the manufacturer is contractually forbidden from independently making and selling batteries. The extra profit to them is nothing compared to the loss of profit incurred by manufacturers if their planned obsolescence schemes were foiled by a third party, so this exclusivity requirements forms the basis of any such contract.
What the above effectively means is this: one battery per phone. One digitizer per phone. One...of each component in each shell, as well as the shell itself, for each phone. In other words, the idea that there are warehouses full of OEM parts is a remnant of the (relatively recent, thus the misconception) past. Let me be as crystal clear as I can be: when you are buying a so-called OEM component for any device today, what you are receiving -- irrespective of what the seller claims -- is very nearly always a part that was removed from another existing phone that had been in use for X hours before it was scrapped and gutted for parts (*) (and when I say very nearly, this is simply to accommodate the sporadic exceptions to this hard rule that exist; of course, if you brought this up with any distributor, they would insist that all their products are magically exempt from this universal fact).
(*) To put it plainly: when you buy a "replacement battery" for your phone, you are buying an OEM component that may have optionally been rewrapped to make it seem like someone else manufactured it. To that, I have to say: please provide sufficient documentation (photos, public records, etc.) to prove "Polarcell" (or Green Battery, et al.) has the resources / manufacturing capabilities to make their own LiPo batteries. When invariably it becomes clear that they don't and "outsource" manufacture, then show me the same records for this imaginary, benevolent, hidden giant that's cool with routinely breaking major order contracts that could instantly turn them into the "persona non grata" of the industry (does "you'll live out the rest of your days in a pain amplifier!" ring a bell with anyone?).
Now, to finally cover the seemingly most baffling aspect of the replacement LiPo aftermarket: the fact that there is so much variance from user to user -- that, indeed, not every satisfied real review is a swindle. When you think about it, the reason is quite obvious and follows from the aforementioned facts: because the replacement battery was taken from another device (i.e. in a used state), the actual wear and tear varies widely and to my knowledge there are only two factors that can help in roughly estimating the likelihood of receiving a near-perfect battery on one hand, vs an utter dud on the other (and one factor merely builds on the worst case scenario of the other):
1. How long has that particular phone model been on the market? Chances are, if it's only been a few months, then the batteries sold come from devices that were smashed, or otherwise rendered inoperable. This means there's a good chance that the battery hasn't gone through too many charge cycles and therefore retains a decent amount of capacity. You could even bank on this knowledge, buy up all batteries at the beginning the moment they start appearing, and later gain an excellent reputation as a seller of quality batteries (yes, LiPo batteries lose capacity even when not in use; OTOH, my Nexus 9 was used for 10 days in December 2015 (before I dropped it and smashed the screen) and remained dormant until the end of last summer. Its battery capacity was 17% when I powered it back up and the AccuBattery app shows remaining capacity to be within 90% of OEM/new rating). Conversely, you could buy them for yourself and keep them for later.
2. If the phone came out some time ago, how much time has gone by since production ended? Because all "replacement batteries" were previously used in existing devices, this helps establish the likelihood that you may still come across a replacement that has seen little use. If it's been years since production ended, it means the probability that any battery you buy has decent remaining charge is very low. But keep in mind: as with anything else involving stochastic math, this means only that the mean remaining capacity of the replacements being sold is low -- not that all of them are. Due to the high number of batteries in circulation, you can apply the central limit theorem of probability theory to establish that the probability function regarding capacity of the replacements forms a Gaussian (bell curve): the vast majority are near the mean, but there are extreme outliers as well (but in diminishingly small quantity). So if you consider yourself blessed by Gaia, you can test this out by ordering a replacement under such circumstances.
As for the rest of us mere mortals: so knowing all this, how badly did I personally get burned? Let's just say, I ordered a replacement for my Nexus 6P last year or the year before (i.e. past production cessation) -- from a well known website that provides excellent DIY repair documents (I feel for the guy because no corporation will logically ever sponsor him, and because I firmly agree with his philosophy; but I'm still miffed after being cheated and cannot ignore this -- so as a compromise, I won't name names) and ended up with a battery that (by rough estimate) about 50-60% of the remaining capacity of the battery I was replacing. That battery was down roughly 50-60% of original capacity -- so you do the math.

Let's just say, I ordered a replacement for my Nexus 6P last year or the year before (i.e. past production cessation) -- from a well known website that provides excellent DIY repair documents (I feel for the guy because no corporation will logically ever sponsor him, and because I firmly agree with his philosophy; but I'm still miffed after being cheated and cannot ignore this -- so as a compromise, I won't name names) and ended up with a battery that (by rough estimate) about 50-60% of the remaining capacity of the battery I was replacing. That battery was down roughly 50-60% of original capacity -- so you do the math.

And the problem with that is that then I can buy a new phone instead. I have no need for 7 batteries at the same time. Min order $200 for credit card outside US.
I've been reading some great things about LG V20 batteries such as the "Perfine 4100mAh" and the "SHENMZ 4200mAh" mainly, not only because of the great battery improvement, but because it seems you don't have to sacrifice the original battery cover since the batteries might just fit without getting an extended battery cover. On the other hand, they seem to be Lithium Polymer batteries. I have the bad habit of leaving my LG V20 charging overnight as I always lose a good 8% battery life during the night if I don't. I've never had a problem with the OEM battery in terms of overheating or anything of that sort when leaving it charging.
Does anybody who has a Lithium Polymer battery on their LG V20 leave their phones charging overnight? I've heard it's a no-no with Lithium Polymer batteries, but they're definitely the future in terms of giving new life to the LG V20. I just want to know what to look for as it's not necessary and smart I'm sure to leave the phone charging for too long; however, that's what some people do.
Are those batteries a great improvement over a regular Lithium-Ion battery based on experience?
I have been using these batteries since last December, and when it comes to charging and heat, I haven't noticed anything that's different from the OEM batteries.
While I don't remember ever charging my phone overnight (my battery level doesn't get low until past the middle of the second day, and I mostly just swap batteries), I have charged the battery in the OEM external charger overnight several times before (you could do it outdoors first if you're scared), and it acted just like any other battery in there: the light turns green when charging is complete, and the heat stops.
As for how much better than the OEM batteries they are in terms of battery life, it's a significant step up. Plenty of people (including myself) have reported their findings on the V20 Subreddit.
I wouldn't be surprised if some of the modern phones actually have these types of batteries inside them.

Okay, thanks for the feedback. I can barely make it through a day with moderate to low usage on my OEM battery. The question would be if the LG V20's charging effectiveness is just as good/effective as an external charger; I would assume the answer is yes. I can't imagine an external battery charger being smarter than a smart phone, but who knows. I would like to do what you do in terms of swapping batteries instead of charging the battery directly from my phone, but my phone case is annoying as heck to remove, and I drop everything so I really need a case at all times.
Any battery recommendations? or are the "Perfine 4100mAh" and the "SHENMZ 4200mAh" some good options like people say. Thanks again.
I actually use an Otterbox Defender as a case if you can believe that, although several plastic clips of the inner layer have broken off, so it's not hard at all to take apart nowadays.
I think all of those batteries should be pretty similar to each other (some of them could even come from the same source). I use the ones from MaxxxJuice which just happened to be the only ones available back in December. The one unique thing about these batteries is that they come with Samsung-branded plastic cases. The Perfine seems to be the most popular due to its cheaper price, but some people reported it being a tighter fit which led to some peeling off its brand sticker to make it fit. If you follow the Subreddit link above, you'll see my old thread on the MaxxxJuice batteries, and I put up some Amazon U.S. links to the other battery brands in there.

Thanks for everything. I think I'm going to give the MaxxxJuice batteries a go. I'll probably just order a pair and see how it goes. By all the reading I've been doing on that reddit link you pointed me to, it seems that the "SHENMZ 4200mAh" seems to be a better fit on the LG V20; however, the "Perfine 4100mAh" although being capable of holding just about the same capacity as the "SHENMZ 4200mAh" based on the reddit posts I read, seems to be a tighter fit around the fingerprint reader since it's a little thicker.
The MaxxxJuice battery seems to be the best of both worlds.

I personally have never had an issue charging overnight. Once it reaches 100% it does a trickle charge, at least in the phone. Got the 4200 that was mentioned by CD. If you are rooted, I suggest the AKT mod. Helps alot for battery also. Best of the mods I have came across based for battery. However AKT is ment for 7.0 last I knew.

Thanks. I'm rooted right now as I have the AT&T variant. The problem is that I'm on Oreo and learned to like it, and I plan on switching to Sprint very soon. As far as I know the Sprint variant can only be rooted if you're on Nougat but can never go back to stock once you root I believe. I wish there was a fully unlocked LG V20 like those iPhones and Galaxy phones that would also work with Sprint; the US996 has CDMA and GSM but won't work with Sprint either.
Just knowing that Lythium Polymer batteries also trickle charge is great for peace of mind though. Not that they're foolproof, but at least it's something.

A rootable Sprint V20 is very hard to find nowadays. It has to be on a security patch level date of May 1, 2017 (software version LS997ZV7) or earlier. So not only does it have to be on Nougat, but also on an older, earlier security update of it. Curiously enough, both Mysticblaze347 and I happen to be using this type of Sprint variant.
There is an older thread somewhere about going back to stock on the LS997 after root, so it is possible, but I'd say a rooted V20 stuck on stock Nougat still beats an unrooted one on stock Oreo by a mile, and you still have the option to go with LineageOS.

I see. In any case, I think it might just be easier to switch to a cheaper GSM carrier and keep my phone the way it is; rooted. Even if it's on Oreo, I don't mind since I've used Google's "night sight" for pictures and it's pretty amazing. I don't want to go back to an unrooted phone without a swappable battery honestly. It's that important for me since I don't care about having the newest fastest phone anyway. All I care about is buying a new battery every now and then, and giving new life to my phone. I also like keeping full physical TWRP backups of my entire device as well as a Titanium Backup copy of all my apps, so root is a must like you said.

I'm with you on pretty much everything you said! I bought 2 Perfine batteries and they're fantastic! I made a point of fully charging them in the phone first and then running them through around 4 full cycles (letting them drop to 5-10% - what would people recommend - letting it fully discharge or charge at a certain percentage?) before I started to switch between them and use the external charger. I was so impressed that I've bought 4 MORE! I plan to keep 2 or 3 of those in reserve as no doubt, they'll become hard to find later on.

Generally, they say you should run down the battery until the phone automatically shuts off (on LG stock it happens the moment 2% goes to 1%), then keep it charged for a couple more hours after reaching 100%, and do this cycle 3 or 4 times overall.
I have attached pics of the instruction sheets from my two separate MaxxxJuice battery purchases (colored sheet is old one, black & white is revised one and has more writing on the back, shown in the second photo).

I leave mine charge overnight in my phone. It is always cool to the touch in the morning.

Good. It seems there should be no difference between the 2 battery types in terms of danger if I ever forget to unplug it at night. I ordered 2 maxxxjuice batteries yesterday. Hopefully I won't have to charge as often as I do now.

After about a week of charging and discharging, setting and resetting AccuBattery Pro, I can see that at least for now the MaxxxJuice battery is the real deal. It is a tight fit and a marginal gap is felt around the fingerprint reader, I don't know how much better or worst it is compared to the "Perfine 4100mAh" and the "SHENMZ 4200mAh" batteries; however, it doesn't get in the way of the fingerprint reader function which was one of my main concerns. I'm very picky about those types of imperfections compared to the original design; however, the little gap is almost nonexistent as everything else is pretty much a stock fit.
As of 8/29/19, this battery still seems to be good. I don't know what the shelf life situation is like with that company, but as of 8/29/19 there is still life left for the LG V20.

been using the SHENMZ 4200mAh for 6 months or so. I charge it over night. normally I use 'battery charge limiter' app to stop charging @ 85%. but not always.
been working very well. kept my stock battery for a back up.

I am using this same battery for almost a year. I usually can't kill it in a day, which I definitely could the stock batteries, but I still charge it all night almost every night, and it seems about as good as it was when I got it. I usually end the day at about 30 to 50% at 9:30 it 10pm.

I'm also looking for a new battery in 2021. I didn't want to start a new thread since there seems to be quite a few out there. It's just my hypothesis, but seems like either the V20's hardware circuitry was inefficiently designed and has a leak and/or there is some proprietary things running in the background be it on the stock rom or in the firmware (telemetry is often there).
Whatever it is, I noticed that the V20 seems to drain even when powered off or on airplane mode, abnormally faster than other devices. I am running on the stock rom.
Lithium Ion and Lithium Polymer batteries usually have protection circuitry built in, but sometimes it's hard to trust that built in protection, especially from non-accredited 3rd party batteries.
Also, LG Chem used to be an amazing battery manufacturer (they still are in many regards, as long as they made it), but all the "OEM" LG batteries I see(including the ones mine came with) are made in China (LG is South Korean)... so I'm not sure if LG contracted(which they have done in the past) the batteries for the V20, or the factory in China is just not up to par with QC(Nothing wrong with the Chinese factory, just saying since it's not the original plant in Korea, things just aren't as set up as the original, etc.).
Any how, anyone have good success with an aftermarket battery? I looked at Shenmz's 4400mah(around there) battery and see lots of mixed reviews. But it would be great to hear from someone on here who might have some long term experience with the product... most product reviews are from people who only used it for a few weeks.

Shenmz is pretty much the best/ most trusted 3rd party battery you can get. The 5380's on ebay are ultra fake, 2300 is what they really are. I have a few Shenmz 4380's and they are legit.
