What the Heck Is Draining My MacBook Battery?

If the charge on your MacBook battery dropping faster than you think it should be, it’s time to look for the culprit. Click the Battery icon in the menu bar and wait a few seconds for the Battery menu to display power information, including which apps are using significant energy. Obviously, you can’t quit apps you’re using, and you can’t control some items that may appear here, like Spotlight, but if an app like Photos is sucking power in the background, quit it until you can plug in again.
