I replaced my battery. My new isn't functioning properly, that why I need to reset the mah count.

If you mean reset battery stats it doesn't work read this >> http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/ <<

You probably bought a fake or a faulty one, there isn't anything you can do except return it.
The battery isn't fake or faulty, I rulled that out. The problem is in the monitoring, it's not reading the mah correctly. It says 12% on the bar menu but the mah stands on -178(thats right negative!!).
I just need to reset the mah count. Can anyone help me?
And I'm not trying to improve my battery life I've already done that.

If you have rooted your phone, try flashing another ROM or just flash the same ROM again. Factory reset and clear all caches.
If not, try doing a factory reset on your phone.

Have you tried to wiping the battery stats while fully charged and still on AC as suggested here:

I am going to do that now and see if it helps :fingers-crossed:

Tried, but did not help, I even tried to charge it off to the most can not, but it did not help.
It is possible that you could have over discharged your battery at some point. If calibrating and the thread mentioned above did not do the trick, you may have a damaged lithium cell. Over discharging can cause weird things to happen to batteries often leading to their failure. Or, you could simply have a faulty battery, or even worse... failing hardware.
I'm not trying to scare you, I just thought this information might be useful to this thread. I hope you get it all resolved.

I agree. It sounds like a damaged battery. Have any of you ever drained your battery completely dead? If yes and you've done so often, you most likely damaged your battery. Lithium batteries should never be completely drained.

What ICS ROM are you running? Is it the OTA update for non-rooted tabs, or are you rooted and flashed one of the custom ICS ROMS? I agree with others that it sounds like a battery issue, but knowing which ROM you are running would be helpful.
It's an official ics but from diffrent region " i dont think it matters " ,, also i dont think my battery is dead because when it goes to 2% it stays like thaypt for hours of using, but when it was normal 2% lasts for less than half an hour

I'm not sure it is related to ICS... I got the same problem with HC a few months ago

Download any free Battery calibrator you can find, from Google store.
it will most probably fix your wrong battery readings.
ps. you may need to have a rooted device for the calibrators to work,but i think (i'm not sure)there is one (don't remember the name) that works with an unrooted phone.
Yes battery calibrator neeeds superuser permissions

I have one more question for you
I installed app named "Battery Doctor"
And in this app, after the normal charge is written:
Trickle Charge
Maintain the liquidity of electrons to extend battery life
And the question is
Trickle Charge really extend the battery life or not?
Second question
I blocked screen,but on the stats it looks,like screen was active for 25 mins, but screen was still locked
Is there any way to check what app cause activity of screen?
Sygnał sieci komórkowej=Cellular signal
Aktywność=Activity
Ekran włączony= Screen on
Ładowanie=Charging

Do you really think that you can "MAINTAIN LIQUIDITY OF ELECTRONS" with an app????????
No no, in this app is section "battery charge" and there are 3 steps - quick charge - 0-80% continuos charge - 80-100% and this trickle charge - 30 min of charging after 100%
And in my question I mean is this 30 min of charging after 100% really extend the battery life, not this app xD
The problem with battery backs
Today i have 68% battery then 0 % after turnon, 20%
It's after calibration

Battery calibration is a myth. Charging issues are caused by faulty batteries or faulty charging code in a ROM.
http://forum.xda-developers.com/showthread.php?t=1460553
I think this app deletes the batterystats.bin file. You're right that this is no calibration. But this could help if he has mystic battery power looses.

That file only stores battery usage stats.
I thought it compares the logged data of voltage and the measures to calculate the charge. And when you've bad stats the system calculate a wrong charge. ...

http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/
Hi.
I've got 2 Galxy S2 with the same problem.
This is what happens.
Booth phones with 60% of battery or more, if i shut down, remove the battery and wait about 5 seconds, then put it back.
My battery returns to 20% or less.
Tried with new batterys, different rom's (cm11, omni, stock), reseted the chip fuel gauge.
Has anyone ever seen this happen?
Is driving me crazy.
Thanks.
Had the same issue. Posted it here. As my battery was 2.5 yrs old I was suggested to get a new one.
With new battery not facing it anymore.
Anyone else ?
What happens if you don't remove the battery? Does it drain normally?
Also, have you tired different chargers / cables?

Hi guys,
I wanted to share with you my experience on my device, perhaps some other have the same problem and has solution.
Before I was using 2000mAh battery but it bloat out so I bought a new 1650mAh battery. The problem is that it just turned off when it reaches 40% without even prompting a low batt notification. I thought I bought a defective battery so I purchased a new one again, but it has the same problem. I was using custom roms btw and flashing CM11 nightlies every day or whenever update pops. Does it affects this or should I just recalibrate the device because my old 2000mAh.
Thanks for the help in advance.

Is this a genuine battery. You could try resetting battery stats or use dorimanx kernel to reset fuel guage.
Thanks for the help in advance.
Well the first battery i bought was just a class A, the second battery I just bought a while ago is genuine and its the same result. I will try to flash stock ROM and see if it still occurs, now I just tried calibrating the battery stats.

Don't they say resetting battery stats has only a placebo effect?
I'm having exactly the same problem. I bought two new original batteries and the problem persists. It just doesn't happen with my 2011 original battery.
Thank you
Well i read some articles that returning to stock rom should fix it well im still experimenting on the problem.

Did you check the battery voltage level just before 40%? If I understand correclty, my guess is that the battery should range from 4.1 to 3.3volts, as it has been specified as 3.7v.
In my case, it was around 3.6 volts when close to 40%, which seems to be a reasonable voltage for 40%. But then it suddenly drops to 3.2v (which I measured with a multimeter, since the phone goes dead at around 40%). I have started to beleive the battery is the problem.

Battery voltage can be measured using apps like cpu-z and go to the battery section. Software readings are slightly less accurate than multimeter but does the job anyway. 3700mV = 3.7V (conversion of mV to V)
