Apple do provide details on how to calibrate a battery correctly; it should be part of your general maintainance, though I'll bet barely anybody bothers in practice. See https://support.apple.com/kb/PH14087 https://support.apple.com/kb/PH14087
- ant6n 11y ago"If your portable Mac has a built-in battery, you don’t need to calibrate the battery." Also, this 'calibration' is just charging and discharging. Which happens normally. Also, the mac doesn't go to sleep, it crashes, so I guess it doesn't get calibrated. Maybe I'm holding it wrong. ;)
- n1000 11y agoIt is about the battery controller learning how much charge the battery can still hold. Therefore it needs a completely empty battery and an uninterrupted full charge. Also on the built-in batteries I found that it helps to get a more accurate battery estimate and improve the "battery health" rating.
