Keeping your MacBook plugged in at all times shortens its battery life. A new feature, called Battery Health Management, will be released with the new macOS Catalina 10.15.5 update specifically to address this issue. It maintains your MacBook’s battery life by preventing chemical aging on its battery.
Apple currently has four different models of MacBook laptops in their line-up: MacBook Air, MacBook Pro, MacBook Pro with Retina display, and the New MacBook. But choosing one over the other is not easy, as each one of them comes in different sizes and specifications.
