In the new beta version of macOS Catalina 10.15.5, which was released yesterday and is available for download to authorized developers, a new and useful function has appeared – battery aging slow down.
The new feature will keep track of how and how much you charge your laptop. Despite the “smart” adapters and all kinds of power controllers, the battery becomes unusable faster if you constantly keep it at the cherished 100%.
A similar feature is in iOS 13 and is called “Optimized Charging”: the iPhone learns during daily charging, so when it reaches 80% of the charge, it can delay the completion of charging until you need to use a smartphone. In simple terms, from 23:00 to 05:00 the smartphone is charged up to 80%, and from 05:00 to 06:00 it reaches 100%.
A new feature in macOS Catalina 10.15.5 works in a similar way: if your laptop is constantly running on a power adapter, the status bar will display 100%, although the battery capacity may be less. There is no information about at what point the laptop will stop charging.
Again, the function is individual for each user and will be trained in the process of use. The algorithm also monitors the temperature of the battery, its physical wear and other parameters that affect the battery life.
The new feature will be available with an upgrade to macOS Catalina 10.15.5 to all MacBook owners with USB Type-C, that is, MacBook Pros and MacBook Airs launched in 2016 or later.
