Apple released macOS Catalina 10.15.5. And this update add a new battery health feature and new FaceTime options that really helpful for MacBook users. The battery health feature could extend the life of the MacBook’s battery, 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. Lithium-ion batteries in a MacBook slowly age over time, which means they typically begin to hold less of a charge as the computer gets older. Apple’s new battery health feature in macOS is designed to slow that aging process and for that now MacBook’s battery will hold more charge over a longer period of time.
The macOS Catalina 10.15.5 comes two months after the launch of macOS Catalina 10.15.4, which introduced Screen Time Communication Limits. macOS Catalina 10.15.5 is a free update that can be downloaded from the Mac App Store using the Update feature in the System Preferences app. 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. The new battery health feature will be turned on by default for new MacBooks that ship with macOS 10.15.5 or after you upgrade to macOS 10.15.5 if you’re using a MacBook that supports Thunderbolt 3.
The macOS 10.15.5 will also let you turn off the feature in group FaceTime calls that changes the size of the portrait of the current speaker, adds controls to let you better calibrate the Pro Display XDR, and has other bug fixes and improvements. The update also fixes an issue where large data transfers to RAID volumes could cause Finder to become unresponsive.
