    Just got this Macbook Pro on April 15th, is this normal to lose 5% of my maximum charge in 11 cycles? I love the Mac, but I like taking it to friends houses and various public places; if I wind up having the replace the battery every 100 cycles, then I might go back to staying home on the desktop.

    Seems fine to me. It'll probably fluctuate a few percentage points anyways. Mine has ranged from 90-95% over the past few days.

    Just a newbie question :D
    But for "cycle" it means a "full charge" or just charging it for like 1 hour is considered a "cycle"?
    And charging it for just a little time is harmful?

    So it's normal for me to lose 5% every ten cycles? Damn. Up to twelve cycles now and coco says I have 94%.

    It goes up and down all the time.
    Try a recalibration and see if it goes to 100% again.
    MIne have been going from 6800-7100 from charge to charge.
    From apple.com:
    So if it drops down more, just call apple and get a new battery

    I've got about 2 minutes to write this before I run out of battery ironically.

    Anyway here are the readings I got.

    Is this normal? How does this compare to everyone else?

    I honestly wouldnt worry. Your MBP is still new, and the battery tends to flux in the begining a little. I wouldnt worry, to be honest

    Battery capacity loss is not necessarily linear. Just because you lost 5% over the first ten cycles doesn't mean that you will lose another 5% over a subsequent period of ten more cycles. Have you calibrated the battery at all?
