coconutBattery displays much more detailed information about your Mac’s battery than macOS.
macOS provides some detail on the health of the battery in your MacBook Air or MacBook Pro, including usage history and an indication of overall health. But it’s pretty basic. To find out more about the state of the battery and its performance, you’ll need a third–party solution, and that’s where coconutBattery 3 comes in.
