Battery life is great for me as well... used it all day long, received e-mails to it throughout the day (have my work e-mail set up on it). txt throughout the day and under moderate use and after an entire day (unplugged at 7:30 am, to 10:30pm) I had 70% battery life left.
Over the weekend I drained the battery and it only dropped 10% after the entire night. Had to play with it for 5 straight hours the next morning to knock out the last 30%.
Pretty cool how features turn off once the battery is at 1% to try to stay on longer to save data, etc.
