Apple’s developer preview of macOS Catalina 10.15.5, which was just released, includes a new feature called Battery Health Management that the company says could extend the overall life of your MacBook’s battery.
With lithium-ion batteries like that found in MacBooks, iPhones, and other portable devices, it’s not a good idea to charge the battery to 100 percent. This, along with rising temperatures, can wear out a battery, shortening its overall charge capacity over time.
According to Apple, with Battery Health Management turned on, the temperature and charging history of the laptop’s battery is analyzed, and then adjustments are made so that the battery isn’t charged all the way, thereby preserving more of your battery’s overall life.
