This week, Apple released macOS Catalina 10.15.5, rounding out a series of system software updates that has rolled out to various Apple platforms (iOS, iPadOS, watchOS, tvOS) over the course of a week or so.

This version of macOS is primarily focused on a new battery management feature similar to one already introduced in iOS. It helps prolong the life of the device’s physical battery by moderating charging based on users’ habits.

With “Battery Health Management” in macOS 10.15.5, Apple aims to increase the life of the lithium-ion battery in each MacBook by limiting that laptop’s maximum charge level when plugged in based on analysis of your charging patterns and the battery’s temperature history. Charging to full unnecessarily can reduce the number of cycles before a lithium-ion battery becomes less reliable.
