So I calibrated my MacBook Pro's battery and the health dropped from 86% to 57%. I have 219 cycles on it
Is that normal?![]()
I was using iStat, but now it says it's 59%
So I guess it's not reliable.
If it fails to improve on the 2nd calibration, give AppleCare a call and setup an appointment to have it replaced. (Also, check to see if it could be your magsafe charger that is acting up, since I had the battery and the magsafe charger replaced at the same time)....
wow that sucks. My 15" pb has 365 cycles and the health is 89%. Im bummed about all these bad battery posts cause im about to move onto a mbp in a few weeks
