Check Your MacBook Battery Health

Where can I see MacBook battery health, capacity and cycle count?

After clicking the button, macOS opens the Battery section in System Settings. There you can see your battery condition and maximum capacity percentage.

• Battery health (%) → System Settings → Battery
• Cycle count & full battery details → About This Mac → System Report → Power

These values are provided directly by Apple and are especially important when selling a MacBook or checking its overall condition.
