UPDATE: ok 8 hours and the battery has 3% left with no volume. is this expected?

You must have the brightness CRANKED! I keep mine at the lowest brightness and get about 14-16 hours out of it. And thats listening to music, watching movies (netflix, air video) browsing, email, chat, etc.

When I'm working I use it all day while I work so I charge every 2 days...sometimes nightly depending on how long I can use it straight or how long im working.

When I'm not working I charge it once a week.

yes i do have brightness at 100%. but is apple's claim of 10 hour battery life on 100% brightness or something lower? am i just be paranoid here or do i have a battery problem (8hours video 100% brightness with muted volume). i want to be sure because i have 2 more days to return this thing.

When most companies say 10 hr battery life they mean at the lowest possible usage settings. If you have the brightness at 100% it is your fault that its not lasting. There was NEVER a claim to last 10 hrs at 100% brightness. Why would you expect that to be possible. The fact that it lasted 8 hrs is EXTREMELY impressive considering how excessively bright it gets (almost blinding!) Now put the brightness at a comfortable level and try again.

ok i read this review and they get ~6-9 hours at full brightness.

Hmm reading this thread made me check my own brightness settings and I was surprised to find the slider at 65%. Just have a rough rule of thumb that 10% is an hour of battery life. Seems to work fine in practise regardless of the app.
