The times quoted by Apple will be with the MacBook running with minimum requirement i.e. wifi off, no bluetooth, etc! i only have essential programs running on mine, the screen brightness reduced and the keyboard light down to 50% the battery performance increases greatly!

With you only getting it yesterday the battery will get better once it is conditioned when it has had a few cycles of charge and discharge

Also try resetting the SMC & PRAM settings! see the Apple links below it is always good to follow these if you ever have performance issues!

RESET SMC LINK

RESET PRAM SETTINGS

Hope this helps

it's rated 8-9 hours but that's with everything practically on low

flash videos and sites displaying flash content will drain your battery life more quickly

won't get 8-9 hours with the screen at 100%

My Screen is at like 70% So far ive been using my MBP for 3 straight hours and its a 49% which is amazing

Normal I Run:

Safari - Youtube FaceBook Twitter and a few other random sites
MSN - Video Calling and Regular Chatting
iTunes - Stream podcast or listen to my Music
Mail - Check my mail once a day


I use Photobooth and Garageband less frequent
