This is optimized battery charging, which helps prolong the overall life of the battery. Occasionally your battery might not show a full charge (100%), even after the power adapter has been connected for a long time. When your Mac is connected to power and using optimized battery charging in macOS Big Sur or later, this menu also shows information such as whether charging is paused and when your battery will be fully charged.

The battery status menu in the menu bar shows how much charge your battery has, whether it's currently charging, and whether your display or any apps are using significant energy. It's best to rely on the battery-health information reported by macOS. Some third-party apps also report battery health conditions, but the data they report might not be accurate or conclusively indicate diminished system runtime. In some earlier versions of macOS, battery health might be reported as Replace Soon, Replace Now, or Service Battery, and might appear in the battery status menu instead of Battery settings: Press and hold the Option (or Alt) key while clicking the battery status menu in the menu bar. Service Recommended: The battery's ability to hold charge is less than when it was new, or the battery isn't functioning normally. You can safely continue to use your Mac, but if your battery needs service or its lowered charging capacity is affecting your experience, get your battery evaluated at an Apple Store or Apple Authorized Service Provider, or contact Apple.Normal: The battery is functioning normally.

The Battery information shown here includes Battery Health: Choose Apple menu  > System Preferences (or System Settings), then click Battery.
