I think my battery is some what going bad. It's 4 years old, so it's a little old, but I figure the battery health would be more or less stable within a certain amount of percentage right?

My battery right now is at 58% health... just earlier it was at 90% health. Yesterday it was at 61% health. During my battery calibration a few days ago, it jumped from 58% to 88% then when I was on battery it dropped down to 60% then went back to 90%. It cannot make up its mind... literally.

The battery still holds a charge of ~2 hours with max brightness, max loudness on speakers and with wifi/bluetooth on.

Has anyone noticed an confused battery? If so, how did you it?
