Following the launch of iOS 13.5 last week, Apple also released macOS Catalina 10.15.5 today. This update brings new functionality to improve Mac laptop battery life, in addition to bug fixes and performance improvements.
The biggest change in macOS 10.15.5 is a new battery health management feature. The goal of this change is to reduce chemical aging of a MacBook battery and extend its life, but without compromising battery life.
Here’s how Apple describes the feature:
The battery health management feature in macOS 10.15.5 is designed to improve your battery life by reducing the rate at which it chemically ages. The feature does this by monitoring your battery’s temperature history and its charging patterns.
Based on the metrics it collects, Battery Health Management may reduce your battery’s maximum charge in this mode. This happens as needed to ensure that your battery is recharging to an optimum level for your use, which reduces battery wear and slows down its chemical aging.
Today’s update also fixes an issue where large transfers of data to RAID volumes could prevent Finder from responding.
macOS Catalina 10.15.5 is now available through the System Preferences app for Mac users. You can check out the full patch notes for today’s update below:
