Over time you may find that you need to do things on your Mac like free up some storage space or change some settings. Additionally, you may notice that your screen isn’t as bright as you would like it to be. MacBooks generally have very good batteries that can last several hours on a single charge. But, like many other digital devices, one of the biggest drains on the battery is the screen.
