I attached my phone to my computer speakers at work today because no one else was around to complain about my music. Anyway I had 99% battery life at 9:00 AM. At 10:30 I was down to 15% and my battery monitor was complaining! I usually get good battery performance from this phone and I find it surprising that a single app like MixZing would drain so much power from the phone. The screen was dimmed through most of this time. I am in a basement office (I know) and have no WiFi or G3. Was the phone trying to connect to the net with the change of each song?? That's the only thing that I can think of. BTW the back of the phone is actually warm. Any thoughts would be appreciated. Thanks.
