    Hi.
    I bought a macbook pro from NYC, apple store 2weeks ago.
    And returned to my hometown, Istanbul (turkey).

    My problem is;
    After a full charge, battery shows at most 2:00 hours of life, where it has to be 7hours. What should i do? i'm not going back to nyc until september. and i'm not sure if i can change it here in istanbul.
    if i can't change, what's this problem about, and what can i do about it?
    or; can i change it if i should?


    -Utility information-
    charge remaining (mAh): 6287
    full charge capacity (mAh): 6879
    cycle count: 15
    condition: normal


    thank you verymuch.

    Sounds like you haven't calibrated your battery. The instructions should be in the manual otherwise there's a really good thread by GGJStudios (can't remember exact name) with quite a comprehensive guide somewhere in these forums. Will post location if I could find it.

    Calibrating the battery does nothing for increasing or decreasing your battery life. It only keeps the battery meter more accurate.

    Your battery seems healthy OP, I suggest you check your usage and verify you don't have a runaway process eating CPU cycles. 7 hours is achievable, with very light use, but you should expect around 5 in real life usage.

    disabling Bluetooth, keyboard backlight and reducing screen brightness can help battery life.

    No problem doing it now. But again, it does not increase battery life, it does only help getting a more accurate battery time and health report.
    Take a look at that FAQ I posted.

    If you have some tabs open in Firefox with flash it can greatly reduce battery life.

    If you're using a MacBook Pro with both integrated and discrete graphics cards, you can install gfxCardStatus to manually select your integrated GPU, which will help reduce power demands and give you more life on a battery charge.

    It seems that running Flash in Firefox or running Google Chrome will lead to the discrete processor being activated and dramatically reducing battery life.
