Hi folks,
I updated to the official Jelly Bean build on Three in the Uk yesterday. When I first got my phone on ICS I played around checking wakelocks etc and managed to get everything set up so battery drain in standby was around 0.5 % per hour so 3 or 4% drop over night (if not plugged in of course). Last night with JB though my phone droppped roughly 3 times that much I'm currently at 70% wiht 11 hours standby and just 34 min screen time. Its not completely tragic but much worse than on ICS so I'm guessing theres a problem
In Battery Stats on the phone, Android OS has 'Stay awake' as 1h 11m which seems way too high and the history details page (with the graph) shows lots of narrow blue lines in the awake section so my phone kept waking up all night long - certainly much worse than before with no new apps, just the updated OS.
So has anyone any tips as to how to fix it? I didn't Factory Reset after so I'm thinking I could try this, but if I do should I backup in Kies first then re-install the backup? Or should I just use the google back up, or should I do a 'clean' reset, i.e. reset it and start from new again? That would be a pain but in my iphone days I always used to set up as new for a new version of the OS so I could handle it!
Anything else I could try?
