[Q] Modified Battery

i was just wondering if we can modify the battery.. what i mean is to operate device with the Li-ion batteries that arent for excalibur.. like batteries designed for nokia having same VDC but higher mAh... is it possible? or will it b of no use.. has any one tried this type of stuff before?

yes
it possible
you can modified NOkia BL-5c with excalibur batery
some people do it in Viet Nam
i'm not good at English so i can talk about it clearly

if you use batrere with a more current(mAh) that will create excess heat in the device, while the problem of voltage (VDC) is up to you is still within the limits of tolerance of the Voltage original battery

but there are 1500mAh battery for excalibur.. does that means tht if we use such battery it will heat the device????
can u explain further????

Any Li.Ion battery will do it. It is also safe to charge it - as normally the chargers are adjusting their charge current by the voltage of the battery. This is linked to chemistry (Li.Ion) and this is identical for all such batteries. The Capacity in mAh does not matter for charging (it just takes longer) - there are also extended capacity batteries available and they are equally safe to use.
Possibly the temperature sensor in the batteries maybe different e.g. for Nokia so the device may refuse to charge it (thinking it is "too hot" - or "invalid") - you will need to try out or rely on reports who have succeeded already. You MUST(!) take care that polarity is identical (+ and -) for a replacement, otherwise you may ruin the device, battery or even your health.

HTC Desire Original battery vs Cameron Sino 2400 vs Bilitong 1650

The opinions below are based on my experience, training and the tests I carried out on the purchased batteries. I am not affiliated to or employed by any battery or phone manufacturer.
I will be happy to retest and add to this report should any supplier or manufacturer believe that I have tested faulty items and are prepared to supply me with another/others to test. The additional information will be added honestly however it tests.
Tests based on a rooted and optimised version of the official 2.3 build of the HTC desire with a standard htc desire 1A charger.
Utilities used included:
Battery monitor widget pro
Antutu battery test
The reference battery is a two year old original HTC battery which is well used but still in very good condition. Capacity reasonably tested and calculated at around 1180 - 1250mAh of the original rated 1400mAh. Given normal projected losses for li-ion batteries this seemed high for a 18-24 month old battery but as other ratings are relative to this, the other estimates should be equally on the high side if anything.
A took great care to fully charge/cycle the new batteries as described by the sellers, and did a full calibrating charge cycle on the original before rating it. Battery stats were cleared for testing as each battery was tested.
Various tests were carried out including using battery monitor widget pro to analyse any different usage/performance and estimate power of each battery in addition to using original as benchmark.
SUMMARY RESULTS (mAh accuracy expected to be +/- 15%)
Antutu test scores. Note these do not define a power rating, only relative benchmarks on the same phone in the same situation. The capacities stated result from the tests with battery monitor widget pro and compared to the confident rating of the original.
*****************************************************************************************************************
2 year old original HTC battery claimed 1400mAh - tested 495 (approx 1200mAh)
New Cameron Sino (in loose packaging) claimed 2400mAh - tested 773 (approx 1900mAh)
New Bilitong gold in original packaging claimed 1650mAh - tested 356 (approx 850mAh)
*****************************************************************************************************************
The Good
========
The Cameron Sino tested is the first chinese battery I have tested which actually gives more (around 50% more) capacity than the good condition 2 year old original. This equates to somewhere between 1800-2000mAh for this battery. This does result in testing to a 50% longer phone life in the same use.
Its available very cheap
The large case back needed by these large batteries and as supplied by the Amazon seller is a good fit, seems good quality. Although effectively doubles the thickness of the phone is easy to hold unlike the reports of some no brand large batteries and larger covers with 'quick break' clips. It actually seems easier to hold to me than in the phones 'skinny' form. It of course feels significantly heavier.
The Bad - some seem very serious
================================
There is some impact on the quality of pictures taken by the deep recessed slots the pictures and flash have to pass through.
The large battery does seem to move some with a bit of a clunck felt which should be easily addressable with a small cushion pad added to the inside of the case.
The Cameron Sino battery I tested (like the bilitongs) does not seem to have proper (or at least working) control and protection electronics, in that neither the voltage or the battery temperature is correctly reported to the phone. Both report a fixed voltage of 3923mV and a relatively fixed 24.x temperature even when the phone is noticeably hot to the touch.
Both the Cameron Sino and the Bilitongs seem unwilling to report a 100% charge. Both stick at 99% although I have seen 100% on the Cameron Sino once, which may have been a very minor phone calibration error rather than the battery actually reporting 100%.
Both the Cameron Sino and Bilitong batteries demonstrated erratic battery % left (which is all they really reported) sometimes going back up significantly after being in light use and often dropping very sharply in reasonable use (wifi and browsing with bright screen).
The original did not do this to any noticeable level, always showing consistent and accurate % remaining, and as the original also reported accurately full range battery voltage and temperature, so is in a vastly higher league in its status reporting and presumably safety.
It seems to me that in both the Cameron Sino and Billitong batteries, the proper control and protection circuitry is replaced by a something akin to a simple resistor/diode type setup which is just enough to fool the phone into actually using these batteries rather than reject them as faulty as would occur if there was nothing on these circuits.
Its worthy of note that the standbye/self-discharge rate on the none-original batteries (all) is actually higher than the original with full protection circuitry - adding to the view that there are something like low quality resistors replacing the control circuitry.
This means that I cant see how any any over or under voltage or over temperature protection is done with the 'compatible' batteries potentially increasing the risk of damage to the phone.
The Ugly?
=========
Ok with the Cameron Sino its twice as thick and a fair bit heavier. But I don't see this as a great issue. It sits nicer in the hand in my view and I'm Less likely to loose it by dropping it un-noticed.
Beauty is in the eye of the beholder
So my personal views in summary.
================================
Based on the one I received, the Cameron Sino will give 50% better capacity than a good condition 2 year old original.
Presumably the gains would be significantly less over a new original HTC battery, and more over a worn out original.
Beware of the apparent lack of protection and control, the increased weight/size and possible camera problems.
If you are using the standard phone software, you could get much better increases by installing one of the optimised versions of the HTC builds available freely from the developer forums. I gained over 50% on the usable life per charge just from installing one of these, and ensuring things like gps and wifi were switched off unless I needed them. (at the touch of an icon).
Even if you don't do this, the latest official HTC 'radio reportedly improves power use significantly over older versions.
*** Do any of these at your own risk and after properly investigating the options.
Finally, I would strongly suggest you completely avoid the Bilitong batteries just as much as the unbranded chinese batteries, which in my experience are unlikely to give much better than 850mAh (whatever they claim) when new and very quickly fade, let alone the apparent lack of proper control and protection electronics (seemingly shared by the Cameron Sino).

Gonna amend the overall view with the following:
As the Cameron battery had 2-3 times the standby/low use drain of the original battery resulting in far more battery drain overnight and when the phone is simply being carried around, the extended capacity would be of far less use to those looking for extra days of light use between charges, and would only be really effective for extending heavy use in a single day.
I have already gone back to using the old original battery.
Possibly use one of the crappy Bilitongs when using GPS in the car in a windscreen cradle as the phone can get quite hot there and I want to minimise hot use of the good battery.

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..."

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

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.

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...

[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.
Calling up @234herobrine432 and all the others

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

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.

PolarCell battery came in and in the phone. 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.

Couple Battery Questions

Got 2 new batteries and I want to keep them for a while, so I have a few questions:
1. Is the OEM fast-charge charger and cable okay to use every day, or will it degrade the battery faster than a slower/regular speed charger/cable?
2. Since I have 2 batteries now, which is the best way to charge them both up? charge 1 in the phone, then swap and charge the other in the phone? Or buy a battery charger (and if so, which one)?
3. Any other helps regarding the chargers and/or cables?​Thank you for your help.

Faster charging will always generate more heat and put more stress on the battery, so slower charging would be better for a battery's lifespan, but I don't think you'll see a huge difference within two years.
By far the fastest way to keep going is having the second battery charged in an external battery charger and then swap when the other battery gets low, followed by charging the low battery in the external charger. Doing it this way also puts the least wear-and-tear on the phone's charging port since you'll rarely use it. I use LG's OEM external battery charging cradle (BCK-5200), but it may be hard to find nowadays. There's currently a used one up for sale in an auction by an American seller on eBay, and there are new ones from a South Korean seller for a higher fixed price. I wouldn't pay more than $25 for one. As for charging time, for me, it takes about 4 hours to charge my MaxxxJuice 4100 mAh batteries from ~5–10% to full. External chargers do not fast-charge, so you'll never put too much stress on the battery that way. Of course, swapping may not be for everyone as it may be inconvenient to take a case off and put it back on.
Unlike the older microUSB cables, bad USB Type-C cables that are not built to certain specifications can draw higher currents and destroy the devices they are charging. A few years ago, a Google engineer reviewed lots of USB-C cables on Amazon to give his view on those. If you need a third-party cable, make sure you get one from a reputable source with good reviews. My preferred USB cable is Anker's Powerline+ due to their extra strength/thickness, and I don't need much flexibility/twistability in my cables. Also, I like how the USB-C end connector is made of one single piece where you don't see any connecting lines around the middle (you can see an example here).
Other thoughts:
As long as there is a supply of extra batteries around and you can afford to buy them when the time comes, then you shouldn't worry much about how you charge your phone. In my opinion, that is one of the main selling points of having a hand-removable battery. I imagine a paranoid person on a phone with a sealed battery would be trying to keep the battery level between 40 and 80% at all times. So really, the only thing to worry about is having a decent USB-C cable and making sure the phone's charging port is clean and not worn out.
In case you are really interested on my detailed charging habits and related things on my V20, I discussed them while reviewing my batteries a while back on the V20 Subreddit.

Thanks!

On that Subreddit, you mentioned you cycled a couple batteries. Did you have to do the whole fully charge and fully drain thing each time you switched to the new battery, or just when you first bought the batteries?

Would like to know the answer to ^this^ as well.

No, I only did the full cycle with the first battery three times, and that was it. The only reason to do that is for the Android software of the phone to get a better sense of your battery level. Of course, it won't be as accurate the longer you go swapping between batteries as undoubtedly they will differ a bit in capacity over time. But fully running down and then fully charging a battery isn't good for its lifespan if you do it too often. The only other times you'd have to really repeat the calibration is when switching to a battery with a different capacity or switching ROMs / doing a factory reset.

So, I got a 4000 Powerbear that I'm calibrating now.
I'm also getting a 4100 Perfine.
Are they close enough that I shouldn't have to recalibrate for the 4100?

Most likely yes. I imagine most of these 4000–4300 mAh Lithium polymer batteries that started popping up this year are very similar, and some may just be rebranded from the same common factory source. Barring a defective battery, if the two batteries had a significant difference in capacity, you could see things like early shutdowns on the smaller capacity one or being stuck at a low percentage for an unusually long amount of time on the larger capacity one.

Great info.
So it looks like all other batteries on hand should not be put into rotation with the higher capacity batteries to avoid inaccurate readings in Android.

Pretty much this. I suppose one could try keeping separate copies of the batterystats.bin file from /data/system when rooted and swap them alongside the different batteries. But that sounds like too much of a pain to deal with, even if it works.

Just to add to this, I found your pics @C D for the charging instructions and there's a note about using 3200mah batteries along with the 4100mah batteries.

Does that mean that if you switch between the batteries, they'll both last as long as they should (the 4100 longer time than the orig. 3200), but the system's percent will be wrong?

My understanding is that if you calibrate the phone to recognize the full 4100mah and then use a 3200mah battery, it will shut down early (but still use the full 3200mah).

Correct. They are warning you that swapping between batteries of significantly different capacities will throw off the accuracy of the phone's battery percentage indicator at all times, especially at the high and low percent values (so an early shutdown can happen when the smaller capacity battery is used). Of course, this won't affect either battery's true capacity.
I'd pay good money for a system that can correctly handle different battery capacities of any amount, but we all know where the future of hand-removable batteries has been heading for the last 3–4 years.

Does anyone charge their phone ONLY to 80 % or so?
If so, what apps do you use to limit this? Any other tips/advice?

I use AccuBattery and it has a notification sound that plays when you hit the target charge percentage, but it's still up to you to remove the phone from the charger or else it continues charging to 100%.
Since our phones have replaceable batteries, I haven't made any special effort to take care of them. I have a pair of May '17 OEM 3200 mAh batteries that are going to get switched out for a pair of new 4100+ mAh Li-Po batteries once I get my second V20 set up. Every charger I use is QuickCharge 3.0 certified except for USB on my PCs and my Pioneer Android Auto headunit USB connection in one car. The vast majority of the time, I charge via QC 3.0. Pretty much the only time I let the battery charge via PC USB is when I actually need to transfer files between the phone and computer.
Before my phone started having issues in the past month with a phantom power drain, I would let the phone charge from 30-40% to 80-90% and then remove it from the charger at night before going to sleep. In the last half year as the batteries have aged, I've let it get up to between 90-95% before unplugging. For the past month, I've been charging the phone four times a day from 40-100% to combat the power drain issue, but that comes with knowing that I don't care about these old batteries or the state of the firmware on this first V20 anymore.
As for when I swapped the two batteries I have, that entirely depended on when I actually ran one down so far that I needed a 0-100% battery swap, which could be months at a time and usually happened while on vacation or away from a charging source for a longer period of time than what my usual home/car/work routine allows.
