In my baterry use indicator in settings, my phone says mediaserver used about 40% of my battery life. Another 50% was from the screen. I was playing slacker radio for a few hours and that's only about 3% of my batter use. I tried using taskiller, to see if this would slow down mediaserver, but it didn't seem to. What is mediaserver and why is it using so much of my battery? I unplugged around 6 AM and it's 2:30 now and my battery is down to 15% so I shut the phone off. I haven't used the phone for much besides slacker radio, so I wouldn't think my battery should die so quickly.
