I have been seeing a pretty good amount of posts lately about how to properly calibrate your battery. This is a quick step by step guide on how to do so.
I will outline 2 ways to calibrate your battery.
The first way is using a free app from the android market (easiest IMO)
The second way is using CWM.
But first.... Some common questions.
Why would I need to calibrate my battery?
Anytime you flash a new rom it is recommended to calibrate your battery to optimize the battery life of your device.
You can calibrate your battery at anytime if you believe you should be getting better battery life.
How does it work?
When you calibrate your battery you are wiping your batterystats.bin. This allows for your operating system to create new battery stats that can drastically improve your battery life.
Using battery calibration app
First, install Battery Calibration by NéMa from the android market.
Once installed...
1. Charge your phone to 100%
2. Without unplugging your phone... open battery calibration
3. You will have to allow root permissions if first time using the app. Make sure the app says your phone is charged to 100% as well. Your voltage should be 4200mV or as close as possible.
4. Click on battery calibration in the middle of the screen.
5. Unplug your phone.
Now your battery stats are fully wiped. To fully create new clean stats follow the next steps.
6. Without charging your phone at all... let it die completely until it shuts off.
7. Plug your phone in and without a break let it charge to 100%
8. Unplug your phone
9. Let your phone die completely until it shuts off.
10. Fully charge your phone to 100% battery again.
11. Unplug your phone.
12. Let your phone die completely until it shuts off (last time)
13. Charge your phone back to 100% again.
CONGRATS! Your battery is fully calibrated!!
Note: it is recommended to do 4 full cycles to completely calibrate your battery but you should notice a difference after the first cycle.
USING CWM
1. Charge your phone to 100% full.
2. Reboot to CWM (recovery)
3. Scroll down using volume keys and choose advanced
4. Choose wipe battery stats
5. Reboot phone.
Now your battery stats are wiped. To fully create new clean battery stats follow steps 6 through 13 above.
As stated this is just a quick guide for reference for anyone having questions regarding calibrating your battery. If I have left anything out feel free to mention and I will add it in asap.

The second is from the Tab forum, but apparently our phones have the same MAX17042 fuel gauge chip which reads open circuit voltage to provide battery stats. As Vlad_z states, deleting the log file does not actually calibrate the battery, this is done automatically with the MAX17042 chip. The 2nd link does give instructions on how to reset / calibrate this chip without a jig.
I have definitely noticed a difference after using the battery calibration app as well as clearing battery stats through CWM.
I did try vlad_z calibration as well. I am still in the process of letting my battery die currently for a comparison. However it has been about 26 hours and I still have 37% battery left with moderate use.
I will be updating the OP to contain Vlad_z procedure as well
Nice post. I always just calibrate through cwm when I hit full charge. I never do three complete drains and recharges though. Usually one complete drain one complete charge and then use my phone as normal. Have you really noticed a difference doing four full cycles?
also it step 6. I've found if you power the phone back on after it dies it will truly kill the battery.
Still cool to get over 36 hours of use on this phone. Almost as good as my old dumb phone(which I sorely miss).
I have 5 batteries for this phone. 2 are 1500mAh and 3 are 1800mAh.
I assume I would have to recalibrate for each battery?

What do you need all that power for? Do you have five devices? I Would think you would calibrate based on which mah you are using since you are only deleting a file on your phone. I.e once for 1500 and only use those batteries.

Internal memory of the fuel gauge chip has room for two battery profiles, it cannot hold 5... so, if you are using all 5 then state of charge (soc) reported back to OS level would be pretty much inaccurate.
You can delete batterystats.bin all day long with cwm or apps - this is just as usefull as dancing with rainstick around your phone.
If you absolutely need multiple batteries then stick with same nominal 1500 or 1800. That way fg chip would report average value, granted your batteries should be the same age and health.
Posts like these are truly helpful, This should be sticked imho. I'm a complete noob to flashing, just performed my first two flashes last night, and it's a job trying to scour through these forums and read through all the posts trying to find the information you are looking for. I did it, and I'm very happy with the results. Damned if I was going to ask a question on these forums. you guys got me scared. hehe.
Anyway thanks, as this was the next piece of info I was hunting for!

In charging after fully discharging the phone, do i charge it while it is off or can i charge it while it's on?
Battery calibration by deleting the file is now known to be complete snake oil. Confirmed in the code as well. Deep discharge cycles, along with heat, are enemies of Li ion batteries. While it seemed a very good idea at the time, following this procedure is now known to be only detrimental to battery life, even if it makes people feel good.

Jeff is correct. Since these instructions the myth about battery calibration has been debunked

Keep the phone between 20-85% otherwise heat will destroy the battery. Charge the phone as often as you can and avoid extra heat from charging.
help..
pls help me.after doing battery calibaration?my battery % was 0 only.how am i gonna fix that?even though i charge so many times.it get 0 % only.pls help me fix that problem.tnx
Necro-rez of a tread that has already stated "don't do this" ain't gonna fix it for you. Why don't you post what your hardware, firmware, and software are in another thread, along with very clearly detailed description of what you did and what happened (with what you expected to happen, if different).
Without that, "Not a bug" "Move along, nothing to see here."
after pressing "calibrate" from app and unplug phone from charger, do i have to let the phone discharged without it being disturbed from any battery usage activities e.g. messaging, play games, browsing internet etc? or I can use the phone while it discharges? i hope to not defeat the purpose of calibrating the battery.

There is no purpose for this kind of "battery calibration" process. It has been thoroughly debunked. It is generally accepted, however, that deep cycling of the batteries shortens their lifespan.
do i need to charge it off, after draining the battery ?
Hi every one,
I was wondering if there is need to recalibrate the battery on each rom update, custom and lg official releases?
Also i bought a 1900mAh battery so I think it need to calibrated for better performance?
Any advice will be great
Sent from my LG-P920 using xda premium
no.
Battery calibration does not affect battery performance, it just changes the accuracy of the battery %age display. There is also no way of calibrating the battery, as it is directly read from the li-ion battery itself. Deleting the batterystats.bin Does nothing besides resetting androids About Phone>Battery Use data - which already resets itself on a full charge (And also broken on O3D GB Roms)
Its actually likely that calibrating the continually will eventually result in considerably worse battery life, as li-ion batteries are best operated between 20-80% charge.

I saw on the battery calibration app, that it must be recalibrated, since each rom has diferent files to manage power, and it will actually help the battery managment.
Thats what i know, im not an Expert.

I saw that too, on battery Calibration by NEMA it says:
calibration needs to be done after flashing a new ROM. but you calibrate.. etc. the whole message that why my initial post was about, I saw other posts saynig that it must so ill do it just in case I dont think that will do anyharm at all.
wasn´t calibration just a matter of charging till 100% when off, then remove battery, insert battery and then start phone and plug again??
i do this and my battery it's all good, although i cna't watch a video for more than 3 hrs hahahaha
It actually worked on my ZTE Blade. I believe it's called overcharging.
hi
i dont think so need callibration after each new rom!
it might harmful for battery!
IDK but i am facing random power off...when i turns it back on it again powers off after the bootanimation...
Chinmay said that it must be a kernel prob and i sholid change the frequency to 1000 ...i changed it and my phone remained on for half an hour and then powered off eralier it used to power off itself within 15 min...
Can someone suggest me that is it the kernel prob or battery prob...
If kernel prob tye suggest me a good gb based kernel...
Thanks You

I mentioned this earlier somewhere.remove your battery and try to rotate it.if it does the battery's swollen and probably gone.

When u over charge your phone, the battery seems to bulge.. Its when u keep it for charging whole night or somthing like that.. When u do that repeatedly, battery bulges.. N thus it become weak.. Low back up n all that..

If it still persists try using the kernal made by adi_pat. I have been using it for a month and still no problem. Also good battery life!!

My old LG battery bulged up like a balloon after 2.5 years and it just died every time i try to use, e.g. connecting wifi or making calls. Or even at random times. And yes, if you can spin it on a flat surface it's probably gone. Mine was at the extent of pushing against the battery cover..
I read somewhere that overcharging the current new type of Li-ion battery is unlikely (some regulating mechanism in the phone that will stop charging even at plugged in) and spoilage is probably due to too many cycles used or simply meaning aging; or manufacturing fault.
i think my battery is completely gone..cant handle my phone for more than 15 min..Around 20 % drain in 10 mains of continous use...this is all because of my foolishness...as this was my first phone i didnt knew about this battrey thing...when the battery used to get at 99% used to charge it again to 100% ...i did this for 1 month or so....at last i ****ed my battrey very deep....
thank u guys for ur consideration and awesome comments....i have ordered a battrey from flipkart !!
Even my battery spins quite well on the floor. Maybe I need a new battery too...
every time i plug my charger into my phone, it says "battery have low temperature, discharge for battery health" or something like that.
but it still recharges when the phone is shut down.
can someone help me?
i already tried another battery, but the result is the same.

Which rom are you on ?
No replies because the error you're having is quite rare , in fact it may be the first i've seen in the forum.
I don't know what causes it , if it charges with device shut down then it's probably software related.
Flash a different ROM then see if it is fixed.
If it's not then it's probably a hardware related issue.

Well, the first one i got this was when i flash GB bin file. then i tried to flash official ICS. with no luck, i flash the paranoid rom and still the same.
it's ok if you don't have the answer but hey, i will appreciate any post that at least tried to help me.
Thanks.

It's probably the adapter because kernel doesn't accept charge for some reason , that's why it charges with the phone off.
Check your adapter ratings , In the original it's rated 4.8 Volts with 1 Amp but anything around 4.5-5 volts and 1 Ampere or below should work but i've had problems with stock roms not charging with an adapter they don't recognize so try it out with original if it's not.
Also , try using the blue kernel from ibluemind , and enable the force ac charge with a file manager , the guide is in the thread.
I don't know if it disables protections in the kernel level , but if it does it might work for you.
Well, half of the phones out there have programmable battery charger chip (AKA Intelligent Li-ion battery charger), and if the BIOS (bootloader) is corrupted or if flashed wrongly, it simply refuse to charge or do so half-way. And as far as charger is concerned, 4.4 Volts minimum is recommended in most case (due to diode voltage drop in the bypass FETs in the charger chip). 5.2 Volts is the maximum as well. Ampere doesn't matter as Li-ion battery is pretty efficient as far as charge absorption is concerned - it generates almost no heat when charging compared to Nickel-Cadmium battery. Of course, go with beefy charger (2 A, 5 V) as the CPU and LCD eats lot more power than what is able to be put into the battery.

There are unlocked ones floating around in this forum - try OS_Hacking's tool - it contain P920 and SU760 versions - be sure to pop in Gingerbread bootloader after flashing P920 BIOS so you can boot up gingerbread ROM or even CyanogenMod ROM.

Short but powerful,
Without all the blablabla straight to the point. I got ?fooled? by a phone company 's expert(?) who told me this was not going to do any damage to my phone, and refused me to give me my money back after i found out that the battery was not good(the same as OEM z710e voltage ratings) when i came home.
I have a z710e, it came out of the factory in 2011. Original battery specifications:
m/n BG58100 p/n 35H00150-02M (3.7VDC 5.62Whr 1520mah)
The battery triple checked by "Expert" and sold by him is a:
m/n BI39100 p/n 35H00170-01M (3.8VDC 6.08Whr 1600mah)
My phone model: z710e (PG58130) original battery p/n: 35H00150-02M from 2011.
Next time I'll check this stuff myself and don't let those people do it for me. They either don't have any good batteries for this model and just sell the one that actually over volts your phone. Or other batteries and so had in his mind to sell me this and don't care about it, like "oh well who the heck cares, this person will never find out and will return to me when his phones is death". Well I'm pretty sure that this will not make my phone last any longer than a year / half a year or less! And i still need it for a year or longer if possible.
Feel free to reply, but only if you know that what you are telling is 100% correct. Please avoid non-valid information or answers, thanks :good:

If you don't understand my actual question, then I'm deeply sorry. Often my stories are not so easy to understand duo to my bad English.
The question in a nutshell is simply : Will this higher end battery do damage to the phone and is my story right, i mean is this battery not compatible with my model because it can do damage duo to over volting the ma inboard/soc (because of higher battery output ratings?)

First of all you should search a little bit more to see that the same battery (35H00170-01M) is offered by numerous companies as a replacement battery for various phone models (Titan, Vivid, z710e...) just like the battery from your phone (35H00150-02M) is offered for the same models.
Then, you can find the same battery (35H00170-01M) offered with different voltages, both 3.7V and 3.8V, and the difference of 0.1V will not harm your phone, cause, you can see it yourself, voltage rating for the original phone charger is 5V and it doesn't harm your phone.
And the last, the other data you got for the battery (Whr and mah) mean only that you have battery that should last longer than the original one you have.
I hope I helped...

It indeed is, but i have really bad experience with replacement batteries. And those small 'voltage increases'. They end up to die quicker a lot quicker in my personal experience. And i think it is also the reason why, many sellers don't include my model in the compatibility list.The 3.8VDC 6.08whr version is meant for the XL and titan version witch is actually indeed the same but +300mhz overclocked.

It don't has warranty. But it's oke. It is a OEM battery they said. Btw it works fine, only had to use another charger with a output of 1.5a. It would not charge otherwise. But well, lets see how long it keeps working.
Haha it seems to not work charging for 5 hours now and still 0% cannot go in cwm recovery and when it starts it will reboot and orange/green led will blink again. I tried to reboot it several times, tried to clean/bend the pins and all the other tips from XDA forum seasrch results and nothing seems to work.. Great =(

Yes i did but it got extremly hot so i switched back to the stock charger. And it actually should be fine? +0.1 volt doesn't matter?
The battery does not hold charge at all. It turns on battery level is 0% and will reboot and do orange/green led indication for as long as you keep it in the charger. When you get it out of the charger and turn it on it will go off as soon as android is loaded up intro the pincode screen. Guy at the store told me the led indication meant that the bettery is at an extremly low level of power and that it just needs to charge some more.
Well i have been charging it for like +5 hours now for sure. Using the OEM charger rated at 5VDC 1A. It is not the cable or faulty charger. If i test the output or on my tablet it works just fine. And with the old battery i'm able to charge it, but the old battery is dead, it does not hold load properly anymore. It drops a lot of times from 80% to 1% in like maybe 30 minutes of usage.
Also when using the GI39100 i cannot get intro adb or recovery..

And with the old battery i'm able to charge it, but the old battery is dead, it does not hold load properly anymore. It drops a lot of times from 80% to 1% in like maybe 30 minutes of usage.
Also when using the GI39100 i cannot get intro adb or recovery..

Faulty battery. It's not about volts, it's about bad battery.
You should require replacement or reimbursement.

It is the second brand new battery the guy in the store put intro it.
Both did the same, it just doens't work.
1. Does not turn on (sometimes when lucky)
2. Holds no charge
I did
1. Wipe battery stats (in the end, like 5 minutes ago from writting. It took me half an hour to get the phone booting while charging)
2. The phone started only twice, now it does nothing anymore (with this new bat).
Also the battery info was all wrong.
When i checked the 1st time when i got it on i went to settings > about the phone > status > batterystatus it did show me(i left it nearly 3 hours like this and still 0%):
- Batterystatus: Unknown <----------------- Before battery stat wipe, after wipe still the same, no power on.
- Battery level: 0% <----------------- Before battery stat wipe, after wipe still the same, no power on.
While it should look like this!
- Battery is being discharged (when not charging)
- Battery level: 93% (old poor battery meanwhile after so much testing already full again)
When i put the old battery in place it works without problems. When i put the new one in it doesn't + battery stats are not even readed by android itself and recovery menu stated a warning. "Warning phone is under-volted" or some message like that. And the LED indicator flash in an unusual way (orange/green) this probably is an error code. Well, complete nonsense because i use the same charger. And the XL version has the same 1A charger, so this makes no sense. The battery is just not compatible.
The battery has been charging for almost 13 hours now. And still 0% + orange/green led flashes.
I have no tools here i had to imprevise with crap, gluetape and a doorbell to get a cracky 5 dollar multimeter working, LoL.
here is the bat output;
a 0.08 v 20 3.52v hv 750 0.07 hv 200 06.8 with other words it should be fine to run and maybe get 50% battery level. But it is still z3r0~ when i put it in my phone.
Topic prefix can be set to [ANSWERED]. The m/n BI39100 p/n 35H00170-01M battery works just fine in the z710e. Confirmed to work, even with 0.1v increase (does not produce more heat or instability, like some cheap fake batteries do without protection IC xD)
I went back to the store they gave me another battery and it instantly worked. So i had two faulty batteries. Lucky me again haha....
Probably or the store where i got it from does not test bats and throws them intro one big box or just very very unlucky.
The battery stats now work, no warning in recovery menu and no orange/green flashing in the led indication.
So if somebody has the same issue as me, your battery is 100% sure faulty. And you should toss it back to the re-seller for warranty or if you purchased the parts loose RMA it.
Get or an good alternative non-oem brand like anker. That is sure to be safe and good of quality. And never use fake chargers from like cheap Chinese tabs or phones. Often they have terrible output and this can badly damage your battery/phone because the output might not be stable enough and drops and increases a lot of times, either using a 2A charger does not make any sense at all. It will go just as fast as a 1A charger because the limit is 1A through(in most phones some can have other ratings). Only thing that can damage your phone/battery is if you go over the 5VDC. More volts = more heat = less lifespan. Amps are taken by the device and volts are given.
Confused
The new battery i have now is a BI39100 35H00186-00M. The 35H00170-01M does not seem to work in a PG58130 z710e or i had two faulty batteries... ?
