I side loaded the Christmas JB leak on my Maxx and everything was great for the first 4-5 weeks. I don't know the exact cause or time, but at some point a couple of weeks ago I started seeing excessive battery drain. I went from going 18 hours in a single charge with 30% or so battery left to barely making it 12 hours and dropping below 10%. I noticed that the Android OS in the battery use indicator was running @ 40%. This seemed his to me as I never noticed this going above 10% before. I rooted the phone and installed BetterBatteryStats and determined that Light Flow Lite and Google+ sync were the major offenders. I uninstalled Light Flow and disabled Google+ sync and my battery life has improved (something to do with wake locks). It's not where it was, but it is better. The Android OS is still showing 40%+ battery use. Is this normal for JB?
