    I'm not even coming close to this with my 2010 macbook pro 13 inch unless I turn my brightness down to 50%, on reboot it defaults to 100%. This is when doing nothing or just surfing the net. I can get about 7 hrs, with my laptop screen turned to 50%. Any tweaks available? I'd love to know how Apple came up with 10 hrs.

    10 hrs is with minimum brightness, no wifi and doing office tasks. Hope this helps. 7 hrs is perfectly normal considering what you are doing.

    Yeah...the 10 hrs is really under "ideal" conditions, but it is attainable. With my "7hr" 13" MBP I usually get 5 hrs with 50% brightness, wifi on and doing normal web surfing (ie: minor or no flash stuff).

    7 hours of surfing the web with just wifi on is pretty good. I would settle for that. I barely get 2.5 hrs. out of my 15" Macbook Pro now:(

    hey, same as you here. That's because of the battery degrading. I wish i had waited and bought the mid 2009 one.

    Just get the battery replaced? Or does it not work that way?

    That aside, maybe it's because my battery has not been calibrated but I don't get that 10 hour battery life at all.

    I get off work at 5 probably start using my laptop around 7 or 8 ... By 11pm it's already showing that it's a little more than halfway drained.

    I have Wi-Fi on, Keyboard lights off, Brightness = 4 notches (25%) ... What gives?

    If you start at 7 pm and it's a little more than halfway drained by 11, you are looking at about 7-8 hours of battery life. That seems in line with what everyone else is getting in this thread.

    they do tests with wifi on, screen at 50%... doing Pages and Safari (no flash)... and they get about 10 hours.

    I'f I'm doing next to nothing.. screen to 50% wifi on... making sure flash isn't going, I can pull close to 9 easy... but I haven't sit with a timer waiting for it to just die when it runs out. I also make sure I have the keyboard light off, bluetooth off, and the auto brightness of the screen off too, cuz that can waste power wether its noticeably changing or not.

    Sounds like what Im getting, although I have the keyboard lights always on, and I usually keep the screen at 75% min unless its at night...
