    Turn down the screen brightness and turn off wifi and bluetooth.

    Tried the usual tricks to extend battery life (screen brightness lower, bluetooth Off)?

    How much are you supposed to get on battery?

    Edit: I am slow lol

    If you're getting 6 without your wifi and bt off and screen set to anything higher than 50%, then you're ahead of the game. They claim 8 or 7 depending upon the graphics card so I'd say 6 is great. Remember Apple tests and claims these so called specs under circumstances that most of us don't compute under. Their specs, IMO, are always at least 1.5 hours off base.

    I have a June 2009 MacBook Pro


    1. Brightness at the very minimum
    2. airport off
    3. bluetooth off
    4. without opening tons of apps
    5. no web browsing
    6. 9400 "better battery life" video card setting.


    I can get 8 hours and 45 minutes. That's after doing calibration once a month (very important).

    With Wi-Fi on, brightness at 50% and browsing RSS feeds, I get 6 hours and 30 minutes.

    Haha. Well then......

    I'm only going by this doc. http://support.apple.com/kb/HT1490

    From Apple:

    If you normally leave your Apple portable computer connected to AC power and very rarely use it on battery power you may want to perform this process once a month.


    Mine is either plugged in at home or plugged in at work. So yeah that's what I do.

    Wow good for you. It's not calibration if you do it every day, it's "normal use." BTW if you're doing this under the impression that once-daily calibration is actually better for your battery than once a week, you are mistaken.

    You're lucky. I'm getting 4 hours with bt off, occasional wireless surfing, screen set to half brightness, no background applications using the cpu. One month old 17" uMBP.

    Will probably ship it to Apple, am just worried it'll come back with greater flaws.

    Check the activity monitor to see if anything is eating your cpu up.
