POLARCELL replacement for BL-T9 (NO MOD) 2450mHa battery for Nexus 5 - Nexus 5 Accessories
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.

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.

GS2 Battery - Fake or Not?
I've bought a a replacement battery on eBay. It looks exactly like the original which came with the phone, except for the white stick at the top (in my HTC HD2 days, the white stick was a sign of fake - or the other way round). Thing is: with my normal usage: calls, video, SMS, WiFi etc. it is lasting around 9hr. The original is lasting more. Not amazingly more, but 20%-30% more, and % metering of remaining battery look way more reliable in the original. Also, a very strange thing happens in the new battery: if I turn off the phone with say 33% of battery, when I turn it on again it may go to 7%. Then it INCREASES up to 13% or more, and then back down again. This may be a fake battery? A defective battery?
its a genuine fake; eg: high quality fake.
Meaning, it is good enough to use (better than the unbranded ones), but I can't expect it to behave and last like the real original one? Thanks
I have same real fake one. Usage seems similar to original and for only £10 I can't complain Sent from my GT-I9100 using Tapatalk

First question has as always got to be before buying a Samsung battery. Have Samsung started selling the battery yet . jje
ebay has been overrun with "genuine fakes". Although they are not technically BAD, the voltage detection is almost always WAY off and very problematic, which leads me to believe the battery could harm devices with long term use. I bought three batteries for my HD2, one which I knew was a non genuine, two which I thought were genuine and only one turned out to be, but it was purchased from a US seller who sold them as genuine or full refund, taken from actual HTC phones. I even bought a battery for my samsung digital camera on ebay once, guy said "GENUINE, NOT FAKE, SAMSUNG OFFICIAL", even sent an original (see genuine fake) box for proof. Popped in the battery and lo and behold: FAKE! Guy offered a full refund and said to ship battery back. Which I never did, because shipping back to China costs twice as much as the item you buy. You reaaaaally have to be careful buying batteries, flash memory or any electronic for that matter off ebay. Crooks everywhere. Especially when they ship from China!

As someone who has worked in that field for a long time I can tell you that most of the products are not worthwhile. The battery ratings are not even good faith estimates. They just stick whatever they want on there. Many of these aftermarket batteries cause hot reboot problems, shut down problems, and other voltage instability related problems leading to hardware shorts or inoperable temperatures. It's just not worthwhile. Especially considering a $500+ phone. If you want to get a backup battery, I say get another OEM one for a spare. Otherwise, find a reputable 3rd party US-based online retailer that you can physically hold accountable if anything happens. It wasn't long ago that I field tested one of the rechargeable 2-way transponders for a big name auto-security company (I won't name names), and their battery that was bench tested and calculated still turned out to be defective. Upon recharge and initial use, it would expand to the point of explosion. It popped right out of the transponder while melting onto the circuit board. you could tell that another 5 seconds plugged in would have been lethal. Just sayin' it's not worth the risk. Damage to goods is one thing. But if the battery actually does explode, the personal injury will be gruesome. Anyway. Good luck in whatever you decide.
This just lead me away from ever buying an overseas extended battery.

Battery Testing Data
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. http://goo.gl/ws87w 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.
Note7 Battery SWAP MOD? Note5 / S6 / S7E Battery etc ?
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..."

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.

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. http://ca.crackberry.com/samsung-wireless-charging-backpack/4A123A24419.htm

Click to collapse 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

Click to collapse 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...
[BATTERY MODS SUMMARY THREAD] So, about battery replacements...
Hello there, Nexus 5 enthusiasts. It's been quite a while since we talked about it and people reported regularly about their battery replacements here on XDA for their nexus 5. With this thread I'm just going to try and ask for help to the modding community, as I've been through hell and back, and after many batteries purchased, dremel quests, soldering smokes, fingers burned and quite a bit of swearing, I'm still here, stuck with a provisory battery (the only LG G2 one that managed to not die) that boasts the astonishing capacity of 1630mAh. I've become a walking charger man, always looking for the next electric socket to plug my N5 into. This has to stop. So I gave up my search engines quest and I'm asking for your human help. I'm picturing this thread as some kind of "summary thread", in which we sum up our experiences and our successes, and see what works and what doesn't. Please post your experience in here if you've been successful in extending your Nexus 5 battery life with a battery mod, and please indicate where you bought the battery (paste the shop link) So, as far as I understand, it looks like: ° Some korean guy bought the 525666 3020 mAh battery from taobao and managed to slam it into the N5 dremeling the chassis. This option, however, isn't viable, as european and american people cannot have batteries shipped to them from China (something about safety regulations), so we Westerners cannot adopt this solution. ° The LG g2's 3000 mAh batteries are too old and will yield abysmal charge (see my experience with it). On top of that, there's virtually no way to know if you're receiving an original one ° Someone said that the N5X batteries are a viable option, and 2700mAh are enough. ° Looking through these N5 battery replacement threads, I've come to know that the 3020 525666 battery from taobao is actually the Xiaomi Mi4 battery. Is this true? If it is, westerners could purchase one outside taobao on ebay or amazon or similar. Would purchasing the Mi4 battery and modding it with the original N5 battery circuit be a good solution? However the voltage of this battery is 4.40V, much higher than the 3.8V of the original. Is this okay or not? The N5X option is certainly viable, however before spending more money, I'd like to make all the options clear for me and for all the people that are still interested in this mod.

The Modders Battery Talk. The truth is you can do the Lg G2 battery mod on a lot of batteries (And devices) it source doesn't need to be the Lg G2 battery and the destination doesn't need to be the Nexus 5. The main things you should consider are the Voltage and the Dimensions of the battery: Voltage: You want the SAME as the OEM mAh: Higher means longer lasting(Not always but assuming the Wh rating is also higher in the battery) Wh: Same as OEM or Higher As for how you can use a 4.4V battery to replace the 3.8V phone. The answer is simple the 3.8V is the nominal voltage rating of the LiPo battery meaning that the power delivery of it is actually between 4.35V and 3.0V (as stated on the OEM Battery). So the fully charged battery will output 4.35V that said if you put a 4.4V battery in a phone that's rated for 3.8V the circuit will stop charging the battery at 4.35V. That said the 4.4V minimum voltage is almost the same but a higher maximum voltage I.e 4.4V vs 4.35V. So Tl:dr you can but it's not the best idea. Now since you want to get more battery capacity, look at alternative LiPo Batteries for batteries that will fit into the Nexus 5. A good starting point would be BL-T32 and BL-T34. Dimensions might not be exactly the same as I have yet to try but the battery itself will work. Alternatively assuming you have a 3d printer you could just get away with printing a new backplate and don't have to worry about the Dimensions of the new battery. As for sites I've used for OEMs are (Made account to answer to this so can't post hyperlinks): spareslg.com => Nexus 5X OEM battery globaldirectparts.com => LG G2 OEM Battery Hope this Helps.
copy pasted from my other reply, i just wanna share my thoughts. i bought a 3rd party battery straight from their official seller, here it is called SHOPEE.com: LOG-ON battery, claims to have 3500mah, which i doubt. but the good thing is, i found a manufactured stickered on physical battery 04/2018. so yea, might as well buy third party one. it is newer, less hassle. and in dollar, its about $4 shipped.
Hello sir i found one battery in aliexpress.com claiming to have 3500 mah capacity which is compatible with nexus 5 blt9 variety. Can i be able to use that extra juice? Does the system detects the extra battery capacity? Is there any modifications like flashing zip or terminal command to be made to make it work? Will it be useful? I'm pasting the link with the reply.i hope I'll get a reply HSABAT 3500mAh BL-T9 for LG Google Nexus 5 Battery E980 Nexus G D820 D821 Nexus5 Megalodon D8 for LG Nexus 5 Battery https://s.click.aliexpress.com/e/tOhxSk9E
Chinese Batteries Explained. There are 3 Major Common Battery Mislabelers in China: LOSONCOER HSABAT DA DA XIONG Lets break down what each of them do: TL;DR: POLARCELL for aftermarket batteries don't trust any of these 3. HSABAT: Buys and sells lower end OEM batteries. When a company I.e samsung/google/apple or any brand orders a batch of batteries they are tested and the batch is ranked based on the tests. Normally higher end brands only accept the best batches. So the mid tier batches end up being bidded on by battery sellers or other resellers. HSABAT is one of these resellers. Except the batches that are normally bid on are 4-6 so the first 3 are normally bought off by the time HSABAT gets access to these for bids and might not even win the tier 4 and only the tier 6. So the batteries are Mislabeled Batteries none the less. I.e they are much lower capacity then stated but they are made at the same plant the OEM are made at. Da Da Xiong: These guys buy USED OEM batteries and relabel them as well as joining on the bids for the lower tier batteries against HSABAT. I.e they are mislabeled if you lucky its a used OEM. LOSONCOER: Same as first 2 but doesn't have as much sales so tends to be even lower end then the other 2. I.e doesn't have the profit needed for major bids. Also goes as far as to tell people that the readings are wrong and not to rip off the labels of the batteries to reveal the OEM logo to avoid unrest and lower reviews.
For people still looking for good batteries and dont live in the EU so PolarCell batteries are quite expensive should check out NOHON. They Ship for much cheaper then polarcell and this is my third battery that is indeed greater then the min of 2220mAh.
I recently purchased a PolarCell off eBay from the EU. Lets hope it makes it.

Based off 3 charging sessions it looks the battery health is 89%. Better than the 87% I had but it does seem to consume as a slower rate.
