    Yeah, so this is what iStatPro tells me. Is this normal?

    What can I do (if anything) to get it back to 100%?

    Cheers!

    Not too amazing, not too low..

    Its pretty average right now. Try calibrating the battery, see if that helps.

    It hasn't really reached a "defective" stage, so I don't think Apple will do anything about it. Continue to watch the battery health though, if it dips to around 80% and you haven't done 200 cycles, then call Apple.

    Just for reference, my macbook battery is at 77 cycles and still has 100% health. One time it showed 98% and I didn't pay much attention to it, but a few days later when I checked it was 100% again, so I dunno. Maybe you should check a couple of days later to see.

    Have you noticed a gradual decrease? Or did it go from 100 to 94 all of a sudden?

    btw, I have the iStat pro widget

    My Macbook Pro's battery started at 97% and has slowly climbed to 99% at 12 cycles. Magic! Haha

    As I said on the guide, these battery health indicators are never 100% perfect, and yes, calibrating the battery resets the indicator. I calibrated my battery, it went to 96% battery health, and a week later shot back up to 100%.
