Apple released today macOS Catalina update 10.15.5 for all users of the stable channel. The update brings a lots of modifications and improvements, including the promise of better battery life on MacBooks.
MacOS Update 10.15.5 brings new Battery health functionality of Apple laptops. When enabled, this feature will reduce your battery’s peak capacity to a level “optimized for your use”. This will allow you to continue using your laptop as normal while reducing battery life. While this feature sounds great, you can turn it off if you want to take advantage of every minute of battery power.
Like all lithium-ion batteries, Apple’s laptop batteries are aging and gradually deteriorating over time. The older the battery, the less capacity it has compared to a “new” state. This means that a MacBook Air that had 10 hours of battery life can only have five or six. Leaving a laptop connected most of the time can accelerate this deterioration.
With macOS Catalina 10.15.5, Apple is therefore trying to alleviate these problems and extend the life of a battery. “Based on the measurements collected, the battery health management function can reduce the maximum charge of your battery when it is in this mode. This is done as needed to ensure that the charge level of your battery is perfectly suited to your use. It has the effect of reducing battery wear and slowing down its chemical aging“Can be read in Apple’s documentation.
In addition, the function also provides information on battery health in the energy saver preferences, just like the iPhone displays battery health under battery settings in iOS.
In addition, the update also brings an important function related to the Pro Display XDR. With macOS 10.15.5, you can finally recalibrate your Pro Display XDR screen. This includes adjusting the white point and luminance of the Pro Display XDR. So you can finally adjust your expensive screen as you wish.
The update also brings some other tweaks and improvements. You can now turn off automatic video resizing in FaceTime group calls. The same functionality was recently extended to the iPhone with the iOS 13.5 update. Additionally, the update brings better GPU performance to certain Mac models when using hardware acceleration. It also fixes a bug that made the webcam undetectable after using a video conferencing application.
macOS 10.15.5 is being deployed and you should already have it installed on your laptop. If you haven’t checked for updates, go to “System Preferences> Software Update” on your Mac.
