Before you start, read and remember, when you disassemble or assemble the battery, DO NOT open the contacts !!! They are made of aluminum alloy, not soldered. The spot welders are welded to them by soldering to the board. After the loss of the coppers, it is practically impossible to solder with such contacts to the board !!! Sometimes pyataks are soldered with refractory solder, it is necessary to heat longer, but in no case do not cut anything !!!
Attention!!! The seller from whom I bought the battery, which we are talking about in this post, has long been selling bullshit, whose capacity is about 3000 mAh.


In view of the fact that there were many questions on alteration, I will try to write a report all the same, well, and collect a bunch of messages in one post.
In general, the autonomy of my device was basically normal, I watched the screen for 6 hours regularly, but once I caught sightthispost u.neo5 about how he tried on the Lenovo s860 battery in our device. Because experience of this "collective farm" had repeated, then without hesitation ordered this battery (Adding from 2017, at the moment, this link sells "thin" batteries with a capacity of 3000-3200 mAh, with which the native cover closes without problems) . The choice criterion was the word original in the description, because in the case of a poor-quality battery, it is easy to return the money by hooking on precisely this word. But the seller did not disappoint, although the battery is not original, but it corresponds to the stated requirements with a margin (more on this below).
The battery rode for about a month, received without damage, it was packed perfectly. Next parse (unfortunately no pictures). So, after winding off the black electrical tape from it, I saw what I expected, the board is soldered to the two contacts of the "can." It's simple, soldered fee, the bank put aside. Next, the worst, analysis of the native battery.
What is left of the native battery

It looks very scary, and it was no less scary to do (just kidding))) The main thing is accuracy. Extreme accuracy when peeling metal plates from the can itself, a very great chance to damage the battery itself. In general, an inquiring mind and playful hands require the exertion of their whims, what's done is done. Unfortunately, I do not have a photo of a separate controller board, there was nothing to photograph, because the battery was disassembled. It is very similar to the Lenovo battery board, only without a loop.

In general, then everything went smoothly, "our" board was soldered to the battery from lenovo (the distance between contacts was about the same as that of our battery, so there were no problems. The main thing is not to confuse the polarity, I determined it with a simple digital multimeter.) charge the front and back of the frame of the native battery, it turned out the perfect length, completely coincided with the length of the native battery.
It turned out such a battery

Then took in handthisnon-original cover "under the iPhone" with a real aluminum frame and a real glass on the back wall and a piece of a stationery knife blade just removed a layer from the inside about 0.5mm (maybe up to 1mm) so that it would close well.

It all took 866r for the battery and 392 for the cover. Although I ordered the cover when I did not even think about the alterations, simply because I liked it.

Testing:
Tel issued almost 9 hours of screen

After that, I passed out and did not want to load in normal mode, although the voltage was more than 3500mV under load.
I went into twrp, crashed batterystats.bin, rebooted - again it was cut down at the final stage of loading. Again I go to twrp, bang batterystats.bin, turn off the device, take out the acb for a minute. After that, it booted in the normal mode with 15 percent charge and gave another 30 minutes to the screen, after which it was finally cut down to 3400mV without being able to turn on in recovery mode.

And lastly.
The control measurement of the tank, more precisely 2 measurements, gave an unexpected result - about4400mAh (I am sure in the tester, he has already checked for half a year with a dozen batteries), while the battery weight is 65 grams.

Good luck to you in the "tuning"! The main thing do not be afraid, and everything will turn out!

Addition 1:Testing real capacity "to return"
Addition 2: It is possible to use batteries from lenovo p780 and p70, all at 4000 mAh and suitable sizes.
Addition 3 (IMPORTANT !!! Added after 4x calls to me with a shout "WHAT TO DO ?? !!"): When disassembling or assembling the battery, DO NOT break the contacts !!! They are made of aluminum alloy, not soldered. The spot welders are welded to them by soldering to the board. After the loss of the coppers, it is practically impossible to solder with such contacts to the board !!!
Addition 4:Excellent report on similar battery replacementmade* valera furman, there is also a pretty visual video.

Old version of this post

For those who are too lazy to use the search, I collected links to all my posts about replacing the 4000mAh battery
Lift it in a hat, if you please, you can arrange it somehow, just do not know how. If someone wants to arrange a normal, then I only.

Thanks for the tipneo5 to him and to no one else, since It was he who suggested a potential battery donor in this post: Power consumption (autonomy) Xiaomi Redmi Note 2 (Post neo5 # 46095712) , and all the rest is the work of hands, no difficulty for me, especially inventiveness was also required, since This is not the first such "tuning".
By the way, you can use batteries from Lenovo p780 and p70, all at 4000 mAh, and of suitable sizes (I did not try it on myself, data from the network).

Addition 1:
Control measurement of capacity, more precisely 2 measurements, gave the result of 4400 mAh
Addition 2:
I measured the mass of the battery. 65g

It turned out to be a completely free day, the weather is shitty, that's why I decided to devote it to measuring the actual capacity of the batteries. Those.out of charge with measurement at the output of the charger (i.e. at 5 volts), and according to the category , with measurement directly on the battery terminals, bypassing the controller board and protection. Or in other words, I tested it "for feedback", as it is more convenient for someone.
The following has been done:
1. Took "white" tester (aka KCX-17) and a precision multimeter FLUKE 73III, connected to the tester Chargers with load current 2A at the output of the tester hung "head" of the flashlight with XML-T9 diode as a load . The gap hung FLUKE positive lead current mode. I was pleasantly surprised, the difference between the readings KXC-17 and FLUKom was likely no more than 10mA. I kept as exactly one hour from the nearest second and saw that the counter in KCX-17 right believes "container". He concluded that KCX-17 has a "pharmacy" accuracy. Glad.
2. Soldered the “controller” (although I would call this crap “protection board”) to my own RN2 bank, charge all of this on the phone to 100% plus another hour. Otpayal back.
3. Directly from a fully charged battery, I applied power to the KXC-17 input, and on the output I hung the same head from a flashlight. Just in case, to control the current, left and FLUKE. Of course, everything is disassembled, soldered pieces of wire, as it should be for a "normal engineer"))). Below is a photo.
4. I waited for the voltage drop to 3V. I tried every 100mA to make a mark about the current voltage. (No, it was not too lazy)))
5. I did the same with the 4000 mAh battery from lenovo s860
6. Well, I was not too lazy to figure out how to draw graphs in Excel (oh, I have long wanted, but there was no reason).
The results surprised. Especially the real Lenovo battery capacity. Thanks to those who read to the end. And to those who at least understand something - many thanks))
Well, then the pictures that comment does not see the point.
If someone is very difficult, before adding. The x axis (this is the horizontal * ROFL *) is the amount of mAh given away, and the y axis is the voltage at the battery terminals.

Rep: (305)
And again with you your battery. After long and, at times, painful experiments, one thought struck me.
Interest in our device is calculated, to put it mildly, through the ass, it is not a secret. A display of 100% is a voltage spread from 4200mV to 4400mV. The same with the lower threshold, the bodies can show 0% at 3600 mV and go down, while the specified lower threshold in the configuration and engineering menu files is 3400 mV
And now the most beloved, math.
We have in configs the following limits: 3400-4400mV. We assume that this is 0 and 100% of the charge, and between them 1000mV, as we see.
And now imagine the worst scenario, the bodies at 4200 mV were removed from the charge with a reading of 100% and disconnected at 3600 mV with a reading of 0%. How many percent of the actual capacity we use? That's right, only 60%. And then I remember how this whole branch was divided into 2 fronts, those with a screen holding about 6 hours and those with about 3 hours. You know, probably, what I am all about.
He himself always had 6 hours (+ - 1 hours) of the screen on his native battery and 8 (+ -) on the extended one. By this add the following:
1. To combat the upper threshold, I advise you to charge another hour after displaying 100%. The tester shows that during this time the battery takes in another 600mA, which is 20%. You can also try to remove the batterystats.bin by hand or by a program such as battery calibration, if the percentages are completely crookedly displayed. The removal helped me a lot after replacing the 4000mAh battery
2. To combat the lower threshold, I advise you to remove the battery for a few seconds after turning off due to full discharge, then put the battery back and turn on the phone. You can get another 20% on top. After two such procedures, the bodies stopped cutting down at 3600 mV, now he himself always lives to the prescribed 3400 mV.

I do not pretend to the truth, all this is just my theoretical conclusions and practical examples. But at the same time, I sincerely recommend to take note and try those who complain about the 3h screen at the peak.

Thanks to all.
I would be a moder, I would put it in a hat.

Another battery
Came as the previous one very quickly. The bottom lines are the same. Shop seller was on the envelope.
Crumpled, dirty and in some blue nonsense. On akb checked on the language - slobovato.
I will try to remake the weekend.
It turns out the location of the controllers is slightly different. And after the collective farm, when you open the back cover, you can see that the battery costs from 4000 lenovo. And with this battery, you can extract information by first removing the battery.

History
- there was such nonsense that when using 3g and VC, the battery at two o'clock in the afternoon is almost at zero. 2g pulled up to 4 days. It does not say about 4.5 hours of the screen. Max 2-2.5 hours
- the frequencies of the CPU and modem did not give tangible results
- AOSP, he also did not save Pts + I sometimes hung on talking
- I always flashed with all the wipes, etc., and so on ...
- at home, if you put the phone on the floor in a corner, it will simply lose the network (3g and 2g at home only on an apple tree - this is not a joke)
- and it infuriates that when the maximum brightness of the phone is heated
Hope for a new battery:
- if 3g or 2g + VK 4 hours of screen
By the way:
- Charges more noticeably longer
The most important thing- how he behaves in extreme situations on pairs! After all, when you need to roll the charge level is close to zero. and it climbs sideways in one way or another.
25.6.2016
- Nothing exploded. While it is difficult to talk about autonomy

26.6.2016
- In the afternoon I wasted the battery so that only the vibration when turned on. Re-charging about 4 hours at a current of 1.35A

27.6.2016
- Just over 4 hours. I threw a 1080p 10gb movie, watched with breaks, a couple of calls, at home a bad network reception on two sim cards, wifi, youtube less than an hour. I'll charge up in the morning

I received today bl211 from disassembly, that is, the original used, redid, put it on charge through the tester for the night (if it works out today to discharge it) the charge is now 84%. The lid does not close, you need to think something. By the way, it turned out to push the battery into the frame from the fake battery. Not without problems, about this in the video.

The quality is disgusting, it is immediately clear that the fake, thinner than the original, the capacity of ~ 1600mah dispute on this battery is closed in my favor. :

workmanship is good, very similar to the original, delivery is fast, the room has arrived in 18 days, is well packed, but the capacity is ~ 1700mah The dispute over this battery is currently open while

As evidence, I put a photo of the usb tester measurements, this is enough to resolve the dispute in my favor

Next week should come bm46, I think that it will turn out to be done
