Welcome to the discussions!

No, that sounds a little low. Have you calibrated the battery as Apple recommends? The directions can be found HERE.

Hi mauchex,

Some user reportedly have their battery showing 99% all the time while charging and they consider it normal.

Here is link to check your battery:

Just use it for reference for your battery life and don't refer and rely too much with what shown on your battery by the software.

Try to reset PMU to refresh the charging behaviour might help.

Good Luck.

I agree with Michael. Battery meters of all sorts are notoriously unreliable and do not always give a true indication of the remaining charge.

Go by what your actual use tells you. Your Mac will come up with a message when your battery is getting low so that youknow to plug it in and charge things up.
