Keep Your MacBook Battery Healthy
Laptop batteries don’t last forever. They’ll wear out slowly, no matter what you do, but bad habits can speed up their aging. Leaving a MacBook plugged in at 100% all the time, constantly draining it to 0%, or using it in extreme heat, are all things that will increase wear and shorten their lifespan.
A quick way to help your Mac while it’s charging is to use Optimized Battery Charging. This feature will learn your charging patterns and automatically slow charging once your Mac reaches 80%. You can turn it on by going to System Settings > Battery > Battery Health and turning on Optimized Battery Charging.
Additionally, avoid letting the battery hit 0% regularly. It’s okay occasionally, but not as a routine.
If you’re unhappy with your MacBook’s battery life and it’s several years old, check Battery Health in the same settings. Once maximum capacity dips significantly and you see a note that service is recommended, the real fix may be a battery replacement.
