Hi guys, I am new here. I have a MacBook pro, and I have a little problem with the battery meter. The battery gets fully charged to 100%, but over time, the battery meter goes down a couple %. Right now it is at 97%. If I unplug it and use it on battery for a while, and then when I plug it in, it charges to 100%, then over time, it would drop a few percent again. Could it be a problem with the battery, or is this completely normal? Sorry if the grammar is a bit off, It is really late, but I don't want to sleep yet Thanks in advance.
