    Hi,

    So I was told that it is perfectly fine to leave your Macbook Pro plugged in when it has the fully charged battery because it does not overcharge it. My question is that my battery charge started out as 100% when plugged in, but while I left it plugged in, it now says that is fully charged at 99%. Is that normal?

    Also, after 2 months of owning my macbook pro, I have had 10 battery load-cycles and my battery capacity is now at 97%. Is that okay as well?

    Thanks in advance

    If you plug your notebook in with a battery percentage of 95% or more, it will NOT charge. It does this on purpose. Do you REALLY need that extra 5%? Considering the wear that your battery experiences every time a charge is placed on it, it's better to let it slide.

    Typical Apple; considering that which others overlook.

    Thanks. I guess I was just worrying over nothing. I just assumed my battery would stay at 100% plugged in and I was freaked out when I found out I had a 97% battery capacity after 2 months and after calibrating.
