I was asked for more information after mentioning this in another thread. I felt like it might generate some questions, so it should have it's own thread.
I wanted more power, but the cheap extended batteries are, well, cheap.
They are OK for the price I suppose, but they lose power quickly and in many cases aren't any better than the stock battery. I wanted a real increase as well, the 2000 from Samsung wasn't going to cut it. So, what to do? Connect 2 OEM standard batteries together!
Materials:
An extended battery back cover from a cheap ebay battery or a friend, etc. The stock Samsung "extended" back cover from the 2000 won't work. I used the one from a Hyperion "3500".
2 OEM 1750mAh batteries (shimshop on ebay has the real deal, about $30/per)
Soldering skill and equipment.
Directions:
Remove the sticker covering the battery. It peels off without too much hassle. You will be left with a bare battery with the NFC antenna on one side. I've attached some images so you can see what they look like taken apart.
Remove the plastic cover on the side with the holes for the battery to connect to the phone.
Now you have a circuit board that is kind of a pain to work with. Both ends you can get to are (+) terminals, as is the metal case of the battery. The (-) terminal is in the center of the battery, see the little hole in the center of the PCB, that's your other terminal. How to connect? Well... There are a couple options. Here's what I did.
Peel up the NFC antenna and let it hang there.
Use a Dremel with a cut-off wheel to cut through the metal connections from the battery to the PCB on the small ends of the PCB.
GENTLY lift the PCB up a little so you can get under there.
On one battery, remove the PCB entirely. Just wiggle it back and forth a bit or use wire cutters to disconnect the (-) terminal. The metal tabs break off EASY. Peel up the NFC sticker as well and just put that bit aside.
Put the second battery over the first. Secure with a bit of tape or something to make soldering easier.
Solder a piece of wire between the two (-) terminals. It doesn't have to be huge. 18ga should be plenty. It's short and likely won't ever see more than about 1A. NOTE: As I mentioned the ENTIRE METAL CASE of the battery is (+). If you short this wire to the metal case, it will get VERY HOT, VERY QUICKLY. DON'T DO THAT. It's bad for the battery, and for you.
Hopefully, you didn't break the (-) terminal off the second battery on the previous step.
Now gently press the PCB back into place on the lower battery. You might have to use a knife to cut some of the plastic between the PCB and the battery to make room for the little wire.
Line it up carefully, as close as you can with both sides and tape it down. Now solder a short wire between both (+) terminals on the battery. You can use the wire and solder to bridge the gap to the PCB from cutting it off before.
Now you have this NFC antenna in the way. Use a small piece of the sticker as insulation under the top 1/2" or so of the antenna on the back. Just to make certain that nothing will short to it. (I don't think it will, but it's cheap insurance) And set the NFC antenna on the new back of the battery. It won't fit quite right, and will overhang a bit. That's what the sticker is for. You could try to extend the connection, but it's more trouble than it's worth.
Remove your earlier tape holding things together.
Use the two stickers you removed from the batteries to cover them back up, sticking the NFC antenna down in the process. Well, most of it anyway.
Now you can try to cut down the tabs on the top plastic to fit properly so you can put it back on.. but I didn't bother. Once I made enough space, it got really flimsy and broke easily.
Now test the connections on the PCB with a voltmeter. Make sure you don't have polarity wrong or anything. Pretty hard to do, but you're going to put it in a $500 phone, so watch it.
If it looks good, put it in the phone and power up. It should work fine. Put the back cover on, and maybe get a case. I'm using the cheap bumper case from ebay. It leaves the back exposed, so just about any battery will fit. It looks a little ghetto before the cover, but it works fine. And it's made from OEM cells, they even have "Samsung" and part numbers laser etched into the metal body. So it will perform to spec, tested with a meter, last as long as a stock battery, which should be a couple years, and if you aren't completely stupid with a soldering iron, be as safe as a stock battery.
Nice hack. I just wanted to point out though that this can be very dangerous. Potentially causing a fire.
Scroll down to the "Cell phone and Camcorder batteries" section:
http://www.ladyada.net/learn/lipoly/
I also found this:
"When using multiple LiPo cells (parallel or series), they have to be charged with a special charger just for them that has been calibrated and is accurate. Then they need to be balanced out with a balancer (some chargers are able to balance themselves or support balancer attachements). So LiPo packs often have a special balancing plug that allows access to all individual cells inside a pack that is only used during charging. The charging is done through the primary terminals, and then the balancer plug is used to top off all the cells to the same voltage. As long as you use a balancer on all the cells somewhere along the line (preferably simulatenously).
It's best to balance all the cells as close to simultaneous as possible. Not a problem if all cells are in the same pack since the charger and balancer do them all simulatenously (duh!). If you use two packs you could charge them separately (I suppose you could charge them simulateously by connecting them in parallel also... as long as they don't get overcharged), and then top of them off separately. But it's probably best to connect all the cells in both packs to the balancer simulateously via the balancer plugs so the balancer monitors and tops off all the individual cells in both packs simutaneously. Depends on what the charger can do.
Still...I'd stick a diode on each pack to prevent one from charging into the other and read up more about it (you never do seem to see Lipo packs where cells are in parallel to increase capacity. They just use bigger cells. There may be a technical reason why they are never seen in parallel within a pack. Possibly due to cells charging other cells. I'd google more about it from RC truck and plane websites."
I don't want anyone getting hurt so make sure it's safe.

On a serious note, it seems cheaper though to just buy a Siedo or Mugen extended battery, when you add up the cost of the battery cover, and the two OEM batteries and the materials. Nonetheless, I hope it works out for you as you put so much effort in to it.

I agree!
Other testing of sedio and mugen didn't impress me for the premium price. Every extended battery for cell phones I've ever seen used this same arrangement. Radio control people do it all the time as well. The RC guys have shown that parallel cells are perfectly safe for years.
Series packs need balance taps and such, but cells in parallel balance themselves. You can't really use a balance tap on parallel cells anyway. The voltage sense would be the combined voltage. The internal resistance of the cells limits the cross cell current as well. RC users do this with 6 cell series packs that have much higher capacity. The only difference is longer wires.
Wish you had pics for each step but nice write up. 2 2100 extended batteries would be even better!

do you have a pic of the battery in the phone?
there are lots of people here that seem to think the mugen and siedo batteries are as good as oem. probably because they write premium a lot on their website and charge double the price of oem. im sure your power pack will last longer than any other extended battery in the 3000mah range.
I'll take a pic once I get to a camera.
Battery ordered and will be in touch with a bench tech in my HQ that is a master at soldering, I'll explain what I need done and hope for the best. I'm also contacting seidio about ordering an extended battery cover by itself.

Here's a pic of the battery installed in the phone. If you want to see with the cover on, really, look at any extended battery thread. They all look about the same, and yours will depend on what cover you get to put on the phone. You can see the NFC antenna peeking out on the top. It doesn't seem to cause any issues so I didn't bother to try extending the leads or anything. And doing that might cause tuning issues, though I'm not sure what frequency is used so it's hard to say.

looks good, is it the battery the same thickness as those 3500mah extended batteries?
have you thought about putting a bunch of those cheap 5 dollar oem batteries from amazon together to make a big external power pack? maybe have them in a 2.5in external hard drive case or something. do you know if you would need a board for this?
the whole point of this was because those cheap chinese batteries suck. With this you know you are getting twice the capacity as your stock battery. This is the one thing I miss from my thunderbolt, my 2750mah extended battery was oem so I knew what i was getting.

Just about yes. I chose not to use the oem 2000 batteries as i didn't think the extra thickness would fit under the cover i have.
And no, i wouldn't use the cheap batteries for an external. If i wanted to do an external, I'd use an RC pack in a case like the hdd case mentioned.
i was talking about oem batteries for older phones like the captivate and droid X. you can get them for around $5 now or you think those are fake?

Hello All,
I toke my HTC One X apart to replace the internal battery with a higher capacity one, as i've tried all the methods listed here to enhance my battery life, but it failed to survive a 12 hours idling - it seems that HTC forgot that the user might use his phone through the day -
anyway, i'm looking for an "INTERNAL" and "HIGHER-CAPACITY" like 2100mAh, 2400mAh battery to replace my 1800 mAh one, any suggestions please?
I don't believe that there is a higher capacity internal battery for the HOX. From what I've read on here is that any higher capacity battery would require the a bigger case for it. Just by opening it up you have now voided your warranty, and any third party manufacturer would not make you void your warranty to increase battery capacity. Your only option is to buy the cases that utilize the pogo pins to increase your battery
thanks for your reply teky, actually i dont care about the warranty, but i believe i can find a higher capacity battery as the iPhone one, i've bought a 2300 mAh from ebay for my old iphone and it was at the same size as its original one, the performance was amazing, it lasted about 2 days with a heavy usage.

likeliness is, if it wasn't physically bigger, then the mah was no more than the original. probably the fact that the first battery was knackered and just buying a new one seemed like it was lasting longer, when in fact it wasn't lasting any longer than a new original battery..
btw, the battery in the 1x is soft...gg, how were u planning on replacing it.
sent from my Viper Bitten One X
i need too an hi-capacity battery, but...is simply to remove the internal battery?
Be careful... A design flaw in the custom battery may cause it to explode.
Every battery I've read about online that promised higher capacity for the same size proved to be a fraud. The best story I saw was posted on the xda-dev forums. The user cut off the outer packaging of the battery to reveal the original battery inside, and printed on this was the real (much lower) capacity.
I don't know much about battery tech :silly:, as I'm about to prove but ... I believe it's basically a chemical reaction that releases power (and the reaction is revered when charging). The capacity of the battery is related to the volume of material available for the reaction, so basically physics is against us on this one.
If it seems too good to be true, it is. If technology were available to produce safe, cheap batteries, of the same size with a higher capacity, why doesn't a single large reputable manufacturer produce what would obviously be a lucrative accessory?
Are we not missing the point that his phone can't do 12 hours idling? My wife's currently very under used one x has managed 7 days and 10 hours from a single charge with 3g on almost zero screen on so true idle.
My used one x can easily make 2days of what I class as moderate use.
There must be some software issue or as Vodafone in Perth did a misconfigured network stopping 3g from going idle and sucking the battery dry.
Cheers
Steve
you can use the battery of the hox+ and get an extra 300mAh ...
but am going to take the batt of my spare one x and see if the battery of the htc butterfly s would fit... you get like an extra 1200mAh
hope it does....

Hello!
It is known that HTC One X+ comes with a battery with more mAh than HTC One X. The difference is fairly 300mAh. We are all wondering if the HOX+ battery fits in HOX?
I just checked out the new battery and main board from HTC One X+ and compared it to our HOX. The battery should be compatible with HOX as it is the exact same size and everything.
Ill replace it and report you the difference.
Also, the main board from HTC One X+ looks like HOXs, it has some minor changes regarding heat dispatching. Pins and connectors are the same so it should be switchable with HOX. Will try that next week and report to you..
VIDEO of how I did it:
This video is not meant to be a full how-to.
It is just to clarify what needs to be done when changing the battery!
If you decide to do this by yourself I take no reponsibility for bricked and damaged devices.
Your warranty can void after you open your device. If you are unsure about the procedure, don't do it!
UPDATE 1 (15min of use):
First notice, charging the battery seems a bit slower. I'd say it is because of 300mAh more that needs to charge - it seems to work flawlessly. 3.6 - 3.7V when using phone, 4.0V when charging so those are the same I will change my system to maXimus 6 as I currently use v4.1 so you will have better look at the battery performance.
UPDATE 2 (2hours of use):
I am absolutely thrilled about the performance of the battery! I am not going to talk about capacity and long lasting battery because it makes no point as it is too soon and battery is not calibrated yet (we need to wait a few days for that) but about difference regarding heat!
When I did some bechmarks with my original hox battery it was alwas hitting about 47℃ and when I was playing nfs:most wanted battery reached unbelievablish fiftytwoes! Now with hox+ battery its ℃ is only at 38℃ and after 40min of nfs:most wanted battery is only at 41℃!!!! It is absolutely more heat friendly and after few hours of it I can only say it is unarguably awesome stay tuned for more!
UPDATE 3 (6hours of use):
Phone feels heavier and more solid! That extra weight (just a lil extra!) gives me a great feeling in my hand. Once again, the temperature of the device is about 5-10℃ lower at all times (surfing on the net, calls, games). There are no more fast and rapid % drops. The battery drain could be related to the heat of battery itself - since hox+ battery is cooler, those drains are gone. I can see some difference in battery performance - power on time, but it is too soon to tell more. My opinion: a little change for the device that makes it look like its on drugs.
UPDATE 4 (3days of use):
I did some battery tests today, tho only 1 day after installed new rom (v8 from football). You have the picture bellow. I am impressed with the battery already.
I can once again confirm all the 3 UPDATEs again: temperature is lower, phone just little heavier, needs more time to fully charge.
Most important: I can deffenitely tell that it already lasts longer. % drops are slower - one of the best feelings after you use One X (battery hungry device) for a while. I'll post my first one-day usage report in a day CHEERS!
UPDATE 5 (4days of use):
So this is the first battery stat update. I can only tell that I am absolutely amazed about how easy I got almost 6hours of screen ON! With 17% battery left! That really is outstanding. It is not only the capacity that makes the difference - heat drained the original battery (gone with the new one x+ battery) and thats the reason for even better result in my opinion.
Check out the pictures:
(Running on the "maXimus V8.0.1")
Looking at the picture, the X+ battery is rated 3.8V, and not 3.7.
That may cause issues with charging circuit, for example.
Very interesting... will follow your updates.

that change is irrelevant, it does not effect charging circuit. that battery from hox+ is within acceptable normal range for a full charge. nothing to worry about. also its a minimal change that can't affect your phone as it only has single phase electric power
Can you post some screenshots of battery info and performance after a few days using it? Thanks
Where did you get the battery ? Changing the battery difficult?
Minor changes regarding heat dispatching? Means the HOX+ is definitely running cooler than HOX.
And yes it would be really good to see battery stats!
Cheers!

Those minor changes are on the main board: alu on the top of the nvidia chip is cut so the chip is actually looking from the main board and nothing is between chip and copper foil for better heat dispatching. About changing the battery, ill upload the video how I did it .. maybe today if I will have time
hox+ battery is not easy to get right now ask at htc service centers if they would sell it to you
I hate to break your bubble but I just went from a One X, to a One X+ and I am very disappointed of battery life.
Of course it is possible that the One X+ battery to have better results on the One X

Shouldn't be that difficult. There are a lot of how-to's on opening the One X. Look for example in the threads about the WiFi problem. If you have it open, it can't be difficult anymore.

Opening the shell is actually the easy part. It gets complicated because battery has connector on the bottom part of motherboard so you have to detach whole motherboard from chasis and disconnect all the connectors on it to reach the battery connector. I will post a quick video tomorrow, maybe a how-to will follow one day but i wouldnt suggest that to anyone who has no experience .. you can damage your smartphone!

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..."

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...
Does anyone happen to have a HTC10 battery lying around that they could measure for me?.
I'm just trying to figure out if with some slight modification to the plastic frame it would fit in the htc9. Obviously a more recently manufactured battery with an extra 100mah would be a much better option than older stock htc9 ones. Soldering the HTC9 battery connector to the 10 battery shouldnt be a problem at all if different.
Thanks.
