Battery drain in Android 4.1.1 (Jellybean) on Samsung Galaxy S3
The Jellybean just deployed for O2-UK customers this week. Obviously, I have planned to update it but I heard a lot of stuff from forums etc about the battery drain in Jellybean.
Is this true? The Galaxy S3 battery is already bad enough to be honest and I don't want even more drain.
Also, are there any major bugs?
