In macOS Big Sur or later, Optimised Battery Charging is designed to improve the lifespan of your battery and reduce the time your Mac spends fully charged. When the feature is enabled, your Mac will delay charging past 80% in certain situations. Your Mac learns your charging routine and aims to ensure that your Mac is fully charged when unplugged.
On Mac computers with Apple silicon or the T2 security chip, Optimised Battery Charging is on by default when you set up your Mac or after updating to macOS Big Sur or later.
If you need to have your Mac fully charged sooner, click the battery icon in the menu bar, then choose Charge to Full Now.
Check the charge status
When Optimised Battery Charging is active, the battery status menu displays when your Mac will be fully charged or whether charging is on hold. If you keep your notebook connected to a power source most of the time, you may see the message "Charging On Hold (Rarely Used On Battery)" when charging is paused.
