Freeze and Battery drain.

I had about 80% of battery life. Using Skype then phone went black and froze. Held down power button to restart and phone came back on but required a charge as the battery was down to 12%. Wtf happened? I did press data connection on while on wifi before it happened. Could that be the issue? Am running ICS Android 4.0.3.

Interesting problem:battery

Hi friends, I have a big problem.When I shut down my s3 and open it after 8 hours, my battery discharged about % 12 -15 t,that is, my S3 is discharging when it shut down. Now i ama using Turkbey rom v17 but i have the same problem with 4.0.4 and 4.1.1
What can you say about my problem?

It doesn't discharge when off, it's a problem with battery calibration when on. Try to shut it off and on immediately and you'll see the same.

Wow, that's super weird... Is it possible that you have too many programs running in the background? I downloaded the battery saver app and it keeps my battery from going on the fritz, might help you too
İ have not a problem with my battery life only with discharging when off ...

how fast?
tried charging it via usb port on a PC/Laptop?
I get 80% in like ~2h. I once activatet the fast charge script.but After i recognized the problem i wiped all and flashed other roms. Might be an Hardware Problem? Everything is working but drains too fast

I don't know autralian voltage, but 2 hs sound about right to me.
Try to find out what is that is draining your battery, what are you doing diffrently since you got there.
Try pluggin it to the pc/laptop, let it juice up and then see if it drops like when charged via AC.
I didnt change anything. Is it possible hat somethings wrong with the Hardware? I got 50 % usage by the display. But i set it to very dark. I dont understand it: (

Has your phone switch from 3G to H or H+?
Yes it switches to h and h+ sometimes. But i think its the same in flight mode.

Try JuiceDefender app. Works very well for me!
I am using an AC switch that generates 230 Volts out of the 12 Volts cigarette thing from our car. Might it be that this is not working fine with my device?
