I haven't changed anything or even installed an app the last week. My phone was at 70% this morning, and stayed this way until about 2pm. I didnt use it at all. (i was sleeping) At 2pm i recieved a call and was on the phone for 2min. After this call i put my phone down and went back to sleep. I woke up at 5pm and my phone was at 30%.... I am perplexed here. I went to the "battery use" thing and it said: Cell Standby 70% Display 5% Juice Defender 4% Phone Idle 6% browser 5% android system 3% Voice Calls 3% Pocket Empires 2% Wi-Fi 2% How could the cell standby drain my battery so fast? I know for sure that none of my programs were being used at the time, those other apps shown like empires i played early in the morning. SHould i change my kernal? Or do you think its an app issue?
