Apple Releases macOS 10.15.5 with New Battery Health Management Feature

Member of the AppleVis Editorial Team

Apple has today released macOS Catalina 10.15.5 to the public.

New in macOS Catalina 10.15.5 is a battery health management feature. According to MacRumors, battery Health Management is designed to extend the overall lifespan of a Mac notebook by reducing the rate of chemical aging.

Battery Health Management analyzes the battery health of a laptop and its charging pattern, and in some cases, it will preserve battery longevity and health by not charging a MacBook to its full capacity. Keeping a MacBook charged at its full capacity at all times can reduce battery health.

When a Mac is used plugged in and the battery is kept full all the time, the Battery Health Management feature will kick in and stop short of a full charge.

Battery health management can be enabled and disabled in the Energy Saver section of System Preferences.

Our testing of macOS Catalina 10.15.5 suggests that it brings no fixes, regressions or changes specifically for blind or low vision users. However, as we always stress, we can make no claims on the completeness or accuracy of our testing. We are only a small team, and it is simply impossible for us to test all devices, configurations, applications, and use cases. Accordingly, to help us ensure that the information on this page is as complete and accurate as possible, please let us know in the comments of any fixes; enhancements; or regressions that you find in your own use of macOS Catalina 10.15.5.
