Apple has released macOS Catalina 10.15.5 which includes a new battery health management feature to help improve the battery life of MacBooks.

Much like the feature that has been available in iOS for a little while now, battery health management helps to improve longevity by reducing the peak capacity of a battery. In addition to this, the latest update to Catalina also improves the appearance of Pro Display XDR monitors, and fixes various problems including issues in FaceTime and Reminders.

While the battery-life extending options will be welcomed by many people, it's not something that everyone will want to use. Recognizing that batteries become less effective as they age, Apple automatically reduces the maximum charging capacity, which -- in the long run -- results in a longer-lasting battery.

If the new battery health management feature is something you'd rather live without, you can disable it:

  1. Head to System Preferences and click Energy Saver
  2. Click the Battery Health button
  3. Uncheck the box labelled Battery health management
  4. Confirm that you want to disable the feature by clicking Turn Off
