    So I just go a new umb 13 and since opening last week the battery only charges to 99% after the first charge (went to 100% only the first time). I ran it down once to see how long the battery would last and when i recharged it, it says its fully charged but only at 99%.
    I then tried calibrating it but it once again stop at 99%. It has 3 load cycles so far.
    Is this normal?
    Sorry if this has been asked before im a newbie to a mac and i tried searching for it but couldnt find anything.
    Thanks

    It is normal. This is Apple's way of not letting the battery overcharge.

    What? That's not true.

    To the OP:

    I had this problem a few weeks ago, battery stuck at 100%. Calibrate your battery, it solved the issue for me. Charges to 100% everytime now.

    It does not charge betwenn 95% & 100%. It will only charge when it drops to 94% or lower.
