    Same here. Doesn't Apple claim 6 hour battery life?

    1 major problem with the Macbook IMO is that there's no way to automatically set the brightness to a lower level when using battery power, something that is commonplace in PC laptops. So if you crank up the brightness when connected to the AC adaptor, don't forget to crank it back down when on battery power. I can notice the estimated hour left increases quite a bit when I decrease the brightness on my Macbook. With wifi and BT on, I get around 3 hours battery life. With BT off, low brightness, wifi on, speaker off, I sometimes see the estimated battery life being 5 hours.

    I get 4 hours out of mineeeee. Which is the best battery life on a laptop I've ever had (coming from moi, the owner of an ancient HP Pavillion that ran down from 100% to 5% in 50 minutes, pfft).

    You're right. 3 hours doesn't sound great, but many PC laptops don't fare much better either (exception is Sony TX series). However, some PC laptops can be configured to accept a second battery in the drive bay (usually sacrificing the optical drive), boosting battery life into a more desirable number. Alas Apple's design team doesn't seem to think like that.

    You can configure your macbook so that when your using your battery the brightness is turned down. Go to system preferences, energy savings select battery, select options and then just check the option for reduce the brightness of this built in display when using this power souce.

    For me, I get about 4.5 - 5.5 hrs of battery life when I'm just surfing the internet with my bluetooth turned off and maybe something like itunes, mail, stickies and neooffice open...

    I've had over 4 hours without using wireless, but I think that's reduced slightly. I leave it in sleep mode when I'm not using it which uses battery.

    The most I've ever had was about 4.5 hours.

    I judge you when you use poor grammar.

    2.2Ghz i7 Late 2011 MBP: 16GB Ram 500GB Seagate XT HD
    With mine i get about 3.5-4 hours. I have my screen to dim automatically when on battery, but usually just lower the brightness myself also to increase the battery life. With auto dim i get about 3:15 with my brightness set to about 1/3 of full i can get over 4 hours. So i would say with my airport off and my screen dimmed as low as i can get it then i could get close to 6 hours.

    Specs:
    3G Black Macbook 2.16ghz, 2gb, 160gb
    im confident that my 3rd generation blackbook would get 6 hours if i turned screen brightness down and only word processed or web browsed

    i get about 4 hours easily out of it when using heavy applications....mostly having google earth, adium, itunes, safari, ical, mail all open for that whole period

    im quite worried about plugging it back into the mains when its not complete flat though.....

    is it healthy to plug a 40% macbook battery into the mains?

    ive always been cautious with stuff like my MX1000 battery, are macbooks the same?
