I got the full free version of Angry Birds, and it's killing my battery even when not running. Last night, I unplugged my phone (it was at 100%) and played Angry Birds for 10 minutes at 2:00AM. This morning I came to work, and even though I have not used my phone much, I noticed my battery is going down constantly right before my eyes (70%, 60%, by the hour). I got in the car and it was 15%. I drove to work and when I got to work 30 minutes later, I wanted to check, only to find out the phone is DEAD. When I held the Home soft key to see what apps are running in the background (before it died), I noticed Angry Birds was running. That is the only difference. The battery usage feature shows that "Android OS" was eating up 60% of my battery.
