Title: Samsung Galaxy S2 and Jelly Bean Post by: pumbaa on Saturday, July 27, 2013, 19:52:34 Ever since I 'upgraded' to Jelly Bean, my Galaxy S2 has gone from being a great phone to an utter turd. Battery life is now almost non-existent (was fine before upgrading) and barely lasts the day - I'd normally end up with about 70% left, now I'm pretty much always down to single figures, even with very light use.
Any other S2 owners having the same problem? Is there a solution? Title: Re: Samsung Galaxy S2 and Jelly Bean Post by: Batch on Saturday, July 27, 2013, 19:55:40 Back everything up (SMS may be tricky) and try a factory reset.

Check the phone is going into deep sleep when it's not being used. Could be a rogue app keeping the CPU awake which will drain the battery. And this: http://forum.xda-developers.com/showthread.php?t=1179809 Will tell you what 'wakelock' is keeping the phone from going into deep sleep. Title: Re: Samsung Galaxy S2 and Jelly Bean Post by: pumbaa on Saturday, July 27, 2013, 20:22:25 Right, CPU Spy tells me the phone is in a deep sleep for 20% of the time, and running at 200 MHz for 58%. Remainder of states are <10% each. I'm guessing I have a wakelock then?
Title: Re: Post by: Samdy Gray on Saturday, July 27, 2013, 20:29:48 Yeah definitely something preventing it from deep sleeping. Install the other app I linked to, leave the phone for an hour or so and then take a look at partial wakelocks.
