Battery calibration is a myth. Charging issues are caused by faulty batteries or faulty charging code in a ROM.

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. ...

hi, i have a galaxy s3 and its been charging fine and the battery seems to last ok aswel, but i just got the battery monitor widget app from the play store and it says my battery capacity is only 1500mA, but i thot it was a 2100mA battery that came with the s3,
can anyone tell me why it says this? is the battery monitor wrong? or do i need to calibrate my battery or something?
thank you for any answers in advance

Yeah, the widget/app is wrong. These definitely have a 2100mAH battery.
Change the battery capacity to 2100mah in settings.

thanks for the reply, i just got my brother to get the same app, he has the galaxy s2 and it reads 1650mA on his, which is what the s2 is meant to be.
im confused as to why the app is wrong on mine but ok on his one

cheers mate, will my battery last longer now?
No the battery always had 2100mah so will last the same but the App can be more accurate now.
My tab's battery dischargs normaly untill 50% then drops down to 2% and i do belive that its a software problem because the tab will continue working for another 5 hours but you cant raise the brightness or use the camera :banghead:

Have you tried to wiping the battery stats while fully charged and still on AC as suggested here:
http://forum.xda-developers.com/showpost.php?p=29874190&postcount=268
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

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
What may i do?

So... Did u find anything to help the battery issue..?? I am suffering frm the same!
there's a difference with battery when my device is turned on and off!! 4example, it gets 100% (turn on) but ~80% (turn off). i used battery calibrate app but not work, i don't wipe battery stats cuz not in my kernel (suave) and not in rom-installing's instruction

wiping battery stats is in the procedure for flashing any kernel or rom
but it's essential
which battery calibration app did you use?
the only thing the battery calibration apps do is to delete the battery stats
there is no other way to calibrate your battery

your 3g data is on
and the majority of battery drain is due to screen
nothing unsual
for how many hours the screen was on??
it seems that everything all right
as 3g and screen consume huge amount of battery

Yup, i know. I adjusted max brightness at that time and 3g turn on. I dont think the problem comes from battery, otherwise ia virtual infomation (battery)?! I think so. Then how to fix that?

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.
