Yesterday my battery died about 30 minutes after being fully charged. I went to USC and swapped out for a brand new battery. The same thing happened. My battery used to last over a day without having to be charged. Today it's been running for 14 minutes and it used up 56% of the battery life. I'm running CM 7.0.3. I don't know what went wrong, everything was running smoothly up until the other day.
