I take great care of my phone, I have had it since July of last year. I recently noticed that from simply checking Facebook and Twitter in less than 10 minutes, my battery life will drop 8-10%. I keep my screen on medium brightness, and I take excellent care of my phone and I don't ever overcharged it. A week or two ago it would not do this. I have no idea what has been going on with my battery life, even if I rarely use it throughout the day, the battery dies extremely fast. It is never on roaming or anything. Does anyone know why?
