Okay here's the deal. I've had my phone for a few weeks now and after power cycling it twice when I first got it I've had better battery life. I recently decided to cycle it one more time as everyone says to do it 3 times. So last night I killed it then fully charged it to 100. At full charge I unplugged the phone and went to sleep.I woke up about 9 hours later to now find my phone at 72% battery......WTF? For 9 hours of standby. Before hand I was only goin down like 7 or 8 % while I sleep. Am I screwed now?
