    So I've download iStat

    And this is what it is telling me...

    My battery health is 86% and the amount of cycles is 171. is this normal? :confused:

    Because what I've seen as I've looked around people have higher cycles and still have more battery health then I do.

    Thanks!

    Mine is 98% at 517 cycles. Is your battery calibrated?

    Doesn't sound "normal" but you have to keep in mind that the % can go up or down depending on how you use your computer.

    Calibrate the battery, that can make the health percentage go up. When i calibrated my new MBP it went from 97 to 102%. I now have an extra 236mAh. :)

    Calibration doesn't affect battery health. It only makes the readings more accurate. Read the FAQ in post #3 of this thread.
