    So i just bought a 17" macbook pro and the first day of using the battery life was great. i would get 4 hours maybe more out of it. however, as time went by i would barely get 2 hours. i don't know what is wrong with it can you guys help me out? I'm not getting 8 hours like apple is saying.

    Did you calibrate it? Run the battery life down, and then plug it in. If you don't see any big increment of increase, I suggest going to the Apple Store and demanding a replacement battery. :apple::apple:

    Doesn't sound right at all.. At medium brightness with WiFi on, I get at least 6 hours out of it. And that was before I calibrated it.

    Those are pretty bad numbers. Apple will replace your battery for free because it is under 300 cycles. Just take it in and have them replace it.

    Make an appointment. They're free, and they'll replace it for free.

    I wouldn't imagine it taking that long. Better be safe than sorry, either way. :apple::apple:

    It's in the Apple Store. If you can't remember your Apple ID, just make a new one. :rolleyes:

    Don't do that unless you have alot of time to waste. Without an appointment you can easily wait 4+ hours at a busy apple store to see the genius bar.

    wtf why is it saying ur MBP is 124 months old? that makes no sense at all......your 13 MBP should not be 10+ years old thats crazy

    my Coconut results for my 13" MBP are

    I've done I think two full calibrations. (Let the battery drain ALL the way & power off, let it sleep for 5+ hours (overnight) then charge it fully) and I've been getting very good results from my battery :)

    Go to System Preferences, Keyboard & Mouse, and hit the box labeled, "Use all F1, F2, etc... keys as standard function keys". It's probably checked.

    I would get it replaced right away. That is horrible for a few week old laptop. Plus, 124 months?? What??

    after leaving the battery drain overnight and then charging for over three hours.

    coconut results show increased capacity to 98% but I'm still only getting 2 maybe 2 1/2 hours battery life with brightnrss right down and no bluetooth.

    I installed parallels and then Xp, don't use it much at all, could this be a factor?

    Does it get hot and do the fans start running? It could be a runaway process.

    It might be a factor in battery life for when you are using it. When you are not, it does not matter.
