Android OS Battery Drain after 5.9.901 update
Hi, i have a Bionic running 5.9.901, not rooted (didn't 4ever root when getting 5.9.901 upgrade). Anyway prior to this update at 5.5.893, i was getting fantastic battery life and Android OS process was showing about 4% battery usage. Immediately after the update my battery life was awful (After 3 hours of barely waking the phone i'm down to 60% battery life from fully charged). I opened my battery manager to see the Android OS is now constantly using 55-65% of my battery. I've tried everything except doing a factory data reset, which was recommended, but i really want to avoid doing that. Any help or knowledge of this issue would be greatly appreciated. I want to reiterate that this was immediately after the update to 5.9.901... so there were no new apps downloaded and nothing else was done to the phone. Thanks in advance for the help.
