    What's wrong? As far as I know most or at least many laptops won't charge the battery unless it is under 95% charge. If you bring the battery down to 93% and try to charge it, does it go above 95%?

    Have you tried draining the battery below 90% and then charging again? In general, Macbooks will not charge the battery if it is above 95% in charge, as namaiki said.

    It's to prevent overcharging the battery. It's a very minor limitation of the state of the battery technology.

    It will charge up to 100% in most cases, but not if you only drain it slightly from fully charged.

    It's not a permanent effect in any case. Nothing to worry about.
