Well, my battery life is pretty good. Ranges from 6:30-8 hours. My first usage was about 7-8 hours. I was using a minimum of 3 hours of wifi and the rest on 3G-3.5G(if that matters) while streaming music constantly before it went dead on me. When I wasn't using anything what so ever, I got over 9 hours of battery life and it was still going(had to charge at that point because it was dangerously low, lol). But I have to say, if you're using the device as a music player, don't bet on it because it's pretty bad. It went dead on me after 5 hours with about an hour of 3.5G data usage. It drains even faster than wifi....
