Battery information can include current charge, charging state, power source, and supported health details. Availability depends on Mac hardware and macOS.
Evaluate battery drain
Compare similar workloads over time. Display brightness, video, wireless activity, external devices, background sync, temperature, and processor load all change battery life.
A short remaining-time estimate can fluctuate as the workload changes.
Battery health
Battery capacity decreases naturally with age and cycles. Use macOS Battery settings and system service information for Apple’s supported condition reporting.
Unexpected drain
Check CPU activity, screen brightness, browser tabs, video calls, cloud synchronization, and connected accessories. Restart an application that remains active after its work is finished.
Safety
If a battery is swollen, damaged, unusually hot, or causes the enclosure to deform, stop using the Mac and contact qualified service. Software cleanup is not a remedy for physical battery damage.
