    Hey friends,

    Apple.com says that my new macbook should have 5 hours of wireless battery life. When I have the brightness on my screen up full, I have about 2:45 of battery. When it's on the lowest brightness, I have about 4 hours. Do I have a bad battery, or is that standard procedure? When they say 5 hours, do they mean with barely any brightness or CPU being used?

    Thanks :)

    77% battery right now, have 3:02 on full brightness using word, wireless and 3 web browsers.

    Might be something wrong with yours.

    I would say 5 hrs is pretty close. I find the battery life pretty good long as im not doing anything processor intensive.

    Batttery life will vary greatly depending on usage. The number of web browsers open means nothing. Screen brightness, bluetooth, wifi, processor intensive activity, use of optical drive, use of hard drive will all cause the battery life to range from a theoretical max of maybe 5 hrs to an average I suspect of maybe 2.5-3.5 hrs to a minimum of somewhat less than 2 hrs.

    From the fine print on http://www.apple.com/macbook/specs.html

    "Testing conducted by Apple in October 2008 using preproduction 2.4GHz Intel Core 2 Duo–based MacBook Pro units with a Higher Graphics Performance setting. Battery life depends on configuration and use. See www.apple.com/batteries for more information. The wireless productivity test measures battery life by wirelessly browsing various websites and editing text in a word processing document with display brightness set to 50%."

    I actually sent feedback to Apple a couple weeks ago asking if the MacBook battery performance is advertised based on tests with a MacBook Pro. No response.
