Following the launch of iOS 13.5 last week, Apple today has released macOS Catalina 10.15.5 as well. This update brings a new feature to improve the lifespan of Mac notebook’s battery, besides bug fixes and performance improvements.

The biggest change in macOS 10.15.5 is a new Battery Health Management feature. The goal of the change is to reduce the chemical aging of a MacBook’s battery and extend its lifespan, but without comprising battery life.

Here’s how Apple describes the feature:

Today’s update also fixes an issue where large data transfers to RAID volumes could cause Finder to become unresponsive.

Based on the measurements that it collects, battery health management may reduce your battery’s maximum charge when in this mode. This happens as needed to ensure that your battery charges to a level that’s optimized for your usage — reducing wear on the battery, and slowing its chemical aging.

macOS Catalina 10.15.5 is available now through the System Preferences application for Mac users. You can check the full release notes for today’s update below:
