The macOS Catalina 10.15.5 update features a new Battery Health Management feature, designed to extend Apple MacBook battery life by changing how often the device gets full power. Want your MacBook always fully juiced? Here’s how to turn off the feature.
How Does Battery Health Management on a Mac Work?
Battery Health Management on a Mac is similar to the Optimized Charging feature on the iPhone and iPad, but is designed for different uses. This only works on MacBooks that ship with Thunderbolt 3 USB-C ports (all including MacBook Pro 2016, MacBook Air 2018, and beyond).
You know, if you use your MacBook with a monitor, it might stay connected most of the time (like mine). This means that your MacBook is almost always fully charged.
This is great if you are accustomed to going out with your MacBook and charging several times a day. But if your MacBook’s battery is always fully charged, it actually decreases battery life and battery health.
How the Battery Health Management feature takes care of it does not always fully charge your MacBook. In this way, this can reduce the number of full battery charging cycles and extend the life of your battery.
Now, Apple says that it does this smartly, by monitoring your MacBook usage and only stopping the MacBook from reaching a 100 percent fill rate if it knows that the MacBook will be installed for a long time (based on your usage patterns).
But this feature isn’t easy, and is activated by default if you buy a new MacBook or after you upgrade to macOS Catalina 10.15.5 (or newer). What if you always want your MacBook to be charged up to 100 percent, so even if you want to get out, you know that your MacBook won’t run out halfway.
You can do this by disabling the Battery Health Management feature altogether.
