My 2 day old atrix 4g has practically no battery life. It was 100% charged at 6:30 and now at 11:20 I have 30% I've done some light browsing and 30-45 minutes of angry birds and the rest of the time the phone has been idle. It says that media server has used 55% of my battery, I haven't even used any media today! What's wrong here???
