Hi I have read other posts about battery problems but none of the fixes have been able to work for me. I charged my phone overnight last night upto 100%. I took it off exactly 4 hours and 2 mins ago now. the phone was on standby mode and I didnt use the screen at all. Actually I took it off charge, put it on my dresser, and went back to sleep. I did accidentally leave the wifi on but that should drain my battery much. But anyways my battery right now is at 64%. the breakdown reads below: cell standby 32% phone idle 24% Android system 18% display 7% other than that everything else is low. What is going on, should ask for a replacement? Also my gps has never worked if that makes a difference. I even tried to use that samsung gps app and it would never locate a position even in the middle of my parking lot! The phone is great but the battery life and no gps is making me sour.
