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.
