I come directly from the iPhone 4, stable phone, battery last a day and a half...got myself a GS2 last week, boy this phone is hard to keep stable. The Battery lasts maybe 12 hours, it does some freaky stuff. Like during the night, the screen stays on for no reason, then i close it, it turns back on 10 seconds later. This morning, its at 100%, i go take a shower, i come back, the phone is hot as hell, it doesnt want to turn on, i take out the battery and when i turn it back on, surprise, battery at 72%. WHY??? I love android but is it always so hard to keep a phone working correctly?
