The latest update to Mac OS 10.5 Catalina has a new Battery Health Management setting that will enhance how MacBooks manage battery life specially for laptops that are often plugged in and docked for extended periods of time daily.
Granular battery management ensures that batteries last longer through time. From what we understand, this feature prevents batteries from charging to 100 percent, which increase temperature and shorten battery life. You might want to turn this off if you're going on a longer trip and need to max out your charge. Only a company like Apple, who creates the hardware as well as the OS and software integration can offer this level of control.
Apple said that the Battery Health Management feature will be available on all MacBooks that are equipped with Thunderbolt 3, so that means all MacBook Pro models from 2016 and later, and the 2018 or later MacBook Air.
