Apple Releases macOS Catalina 10.15.5 With Battery Health Feature

Apple has released macOS Catalina 10.15.5, the update is now available via the Mac App Store using the Update feature in the System Preferences app.

macOS 10.15.5 introduces the Battery Health Management feature to the Mac, which aims to improve the battery life of the MacBook and reduce aging. It works by analyzing the temperature of the battery and the charging patterns it has experienced. For example, does the laptop frequently get drained most of the way and then recharged fully, or is it mostly kept full and plugged in?

In the latter scenario, when a Mac is plugged in and the battery is kept full, Battery Health Management will kick in to stop a bit short of full capacity to preserve the battery's lifespan (All charging data on the MacBook is confidential. Unless the Mac chooses to share anonymous analysis data with Apple).

Modern laptop batteries are charged to 100% and stored there for a long time, particularly at relatively high temperatures, which will greatly degrade the battery life. Apple has managed to tweak the default battery charging behavior of the MacBook so that it will not thoroughly charge the battery too extreme in some cases to extend battery life.
