I leave my battery charging at night whether dead or not and use the 770 for short stints throughout the day, leaving it in offline mode on standby. I always come home to four battery bars during which time I use it unplugged and it seems to go to half. Otherwise during long weekend runs it lasts more than 3h ours while online and connected. (I don't play movies or mp3s that much). I've had it for over 3 weeks now.

What are your usage trends, charging trends, and battery life?
