Hello,
Today I was playing a MMORPG game on my SGS2 and the percent was 35% and then it kept dropping down and when it reached 13% I suddenly noticed the Battery Percent is only 3%,
What is this??!!
 
So does that already mean the battery is corrupted?
And how can I solve such an error?
Does this depend on the App/Game running?

Turn your phone off and charge to 100%. Then unplug and remove your battery. Leave your battery out for a couple of minutes, then put your phone back together and power on.
That should recalibrate your battery and give you an accurate reading.
 
I haven't had the exact problem but I have experienced a misreading battery a few times with my gs2. Recalibrating fixed it.
 
And what does recalibrate mean?
Removing the battery and keeping it outside for minutes?

Or
Charging while phone is shut down and after recharging to 100 % removing the battery and keeping it outside?

It sounds like the game was a real battery hogger and the battery stats couldn't keep up with the charge. At least that's my thought. How is the drop? Sudden or still gradual but very steep? I do get sudden drop if the phone reboots.

Recalibrating requires a few steps.
1) Charging the battery with the phone off is to try to make sure the charge gets to 100% without disruption.

2) Removing the battery and keeping it away from the phone makes sure there are no residual charge in the circuitry.

3) Putting battery back in should give it a new start, thus recalibrating the reading. If you don't get 100% battery, could always redo the steps.

For your info, this is from what I gathered going through the forums.

Cheers
 
I don't see how that 1% is a problem. If you off and on the phone continuously and it drops 1% every time, then maybe its a problem. Else, its just probably the battery monitor getting to grips with the current battery charge. And don't forget, restarting the phone, relaunching the apps.... all those takes juice.
