So I have been experiencing this issue since i got my g2 about a month or two ago. The battery will be amazing for a few days lasting 36 plus hours. Then quickly it will stop being so great. I'll take it off the charger at 2 am and wake up at 6 to see it at 85% even though wasn't in use. Then I'll have it in my pocket all day with minimum use and it'll be at 40% at 3:30 pm. Then I'll have to charge it again before bed where before I could go a whole other night without charging it. I have reset my phone at least 5times and every time it starts out great then goes bad. I tried turning off Google now. I tried setting maps to not follow me. I even turned off gps. I tried with and without WiFi. I'm just so frustrated. I downloaded wakelock detector but don't really understand it. Says 12minutes for system manager and the other apps are at 40 sec or below. Can anyone help? I have the charger that came with my phone but I have a bunch of Motorola chargers that I also use. I didnt think that mattered but figured I mention it.
