Help! MacBook Pro (Mountain Lion 10.8.2) battery percentage instantly dropped from 100% to 88% right after disconnecting the charger.
Help! I just realized that my MacBook Pro running on Mountain Lion 10.8.2 battery percentage instantly dropped from 100% to 88% right after disconnecting the charger. It's been 333 cycles, age 25months, and 88% battery health. Is it normal for the percentage to drop all the way down to 88 just right after unpluging the charger?
Thanks.
MacBook Pro (13-inch Mid 2010), OS X Mountain Lion (10.8.2)
