Hi my SG2 Bat its crazy, when i charge to 100% and unplug energy cable the percentage down to 90% or in minuts to 60% or in many times to 0% and not charge. I change ROM, Wipe data many times and buy another baterry but dosent work.
please can someone help me
Try Battery Calibration app. And wipe battery stats.
Check that the battery is fully seated in.
i already try this... for example i just try with another battery from my friend and this bat drain to 0% now... :silly:

Hi all, i was wondering this about the battery calibrations.
I read somewhere that doing a battery calibration is some software-thing and not the battery-hardware-itself thing (you know, batterystats.bin).
So... if it is as I said, If I have two galaxy aces, one calibrated and the other dont,
If I fully charged them, will they drain all the battery at the same time? (assumming that everything in them are the same).
And another question... if the battery info keep saved on batterystats.bin, could I use someone else batterystats.bin already calibrated ? (i'm talking about someone with the same rom I have (coderom, flash, gingerreal, etc etc..)
That's it
thanks in advance.

I don't think you can use other batterystats.bin . You need to recalibrate your own .

Since you have 2 Aces why not try it?

"..If I have two galaxy aces.."
I'd say the un-calibrated one will die faster. IMHO
Oops misread. Battstats are constantly changed by the system anyway. You will be able to replace one from another phone but it may be altered to your charging.

the 2 aces are going to die at the same time but one is going to show a gradual battery % decrease and the other one is going to show % jumps... i think
in example: using an app with a battery drain of 10% per hour
calibrated: 10min 99%, 1hr 90%, 8hr 20%, 10hr 0%
not calibrated: 10min 93%, 1hr 88%, 8hr 5%, 10hr 0%
thats what i think...
i don't think any calibration will make your battery last longer, it will show accurate %...
again.. thats my personal opinion

That's what I tought, because you can charge the devices, both of them off, The charge should be the same, and while they are on (unplugged), the drain should be the same, only that the % differs. But, you never know what people know, about that you don't know... or something like that. hahaha
There's one thing I wanna ask you guys; if the battery calibration got messed up, how far will the differences goes?
I mean, could the system tell us that we're low on battery while actually we are not?
Installed Cyanomod... charged the battrey to full 100%, calibrated and after 30sec, the battery goes down to 75%...

It wasn't charged to 100%... the phone shows that its charged... but its really not... so after phone shows that its 100%, keep charging for an hour more... then calibrate the battery... you'll see the difference....
Hi folks,
my Xperia Active shuts down at 25-30%. I tried to calibrate, but occurs after few full-charges again. phone is rooted, using latest stock ROM 2.3.4. Any ideas? I mean if you have an experience with it - gimme any hints / step-by-step advises. THX many times!!!
I would try to delate battery cache,discharge it few times and format it.i have had this same problem but after them few steps my batt work normaly.What i think your battery was not formated properly on the very start of using it.

calibrate - full charge and remove the battery charge info file
format - full discharge batter, turn phone off, full charge and than turn phone on?
thx
Yep this is what I mean mate.

If you've tried calibrating the battery and thats not work it might be that the batterys faulty. Try a different battery and see if that works.

the battery MUST be ok, as it is only 2.5 months in use in the phone. It worked and after I re-flashed the standard ROM, it worked a few charges and now it went crazy. the Battery Monitor Widget is not able to detect the battery capacity (mAh) and when charging, it indicated 100% at almost 4.00 V, where it shall be 4.2V as 100%.
I will completely discharge the phone, and when it shuts down, will put it to the charger, turn it on, calibrate - erase the battery info, unplug, discharge untill it will completely turn off, charge it with phone being OFF and the, after it will be completely fully charged, turn it on.
will see where the rabbit hole goes...

Ok I made a mistake.One day after I installed a new rom,I wiped the battery stats,and the battery was around 40%,after that I had problems with the battery.I mean to make it charge to 100% I had to wait for even 3 days!
So I changed the rom,and wiped the battery stats again,when the battery was about 50%.
The problem is now,I can't make it to 100% to calibrate the battery.I mean my phone shows it's charging and after 2 hours,it didn't add at least 1% to the battery.
So,right now I can't get pass 45% battery,because (probably),the phone is set that is actually the max it can charge.
This might sound stupid but I have no other ideea.The phone shows it is charging,but after 2 hours it didn't charge at all.I tried plugging it into a computer,or a wall charger,the same,the phone remains at 41%.
Is there anything I can do?
Wiping battery stats has nothing to do with your problem.

Try this - Flash a new rom, but wipe the battery stats before that. Don't wipe stats again after flashing :thumbup:

After using the Rom Dragon 1.7, my battery takes several hours to charge, and sometimes even carrying my battery percentage was decreasing, someone knows why?
To get an idea, with the phone turned off, after 2 hours charging the battery is at 49% ...
All you can try is to wipe the battery stats .
That fails reflash rom or change rom .

Either you haven't a Genuine Battery or Charger or both.If not try to calibrate ur battery and try to wipe battery stats.

I also have this type of problem when my phone completely runs out of battery and when plug it in charger it bump to 48%.
I dont the reason behind it that why it happen and whats the reason behind it.
If you have recently rooted your phone and have flashed custom rom in your phone than you may face problem of mis-calibration of battery. For solving this download a software called battery calibration apk ( google it ) . Your phone must be rooted if you wana use that app. but before you calibrate your battery make sure you charge your phone to 100%.
when you 100% open that app and grant the super user permission. Click on calibrate.
what the app does is that it will remove batterystat file from our phone and automatically it generate a new batterystat file in your phon. Thus any faulty or mis-calibrated file will be removed and you will get good battery life.
after calibrating do some cycle charge mean from 100% to 0% and from 0% to 100% without interuption. Do it for 3-4 times and you will see a drastic change in your battery life.
Calibration of batteries is a myth, battery stats is cleared every time you unplug a nearly fully charged device. Also draining modern batteries to dead is not good for them at all so I'd discourage it unless necessary.
