Anyone got any info on battery life? I charged my N1 last night, been listening to some internet radio (less than 30 mins) and surfing the web (less than 30 mins total, I'd say). No phone calls. And maybe less than 20 mins of email. And now my battery is dead. It's 2.30 PM. I'm hoping the battery is either defective or hasn't reached peak performance. I'm not happy.
