Calibrate battery on MacBook Air
Hello,
I read that a MacBook Air doesn't need its battery calibrated but it seems like mine needs to as it suddenly turns off at 5-10% battery.
I recently did never charge it up completely and then got the battery empty - that may be the reason why.
(How) should I recalibrate the battery in my MacBook Air (Early '15)?
