Sometimes you wonder why your iPhone 12 is running slow. One reason could be that a lot of your Apps are open and running. You should always make sure that your Apps are closed when you don’t need them.
From your home screen, swipe up from the bottom. Usually about halfway up is more than enough to show all of the Apps that are open on your iPhone 12. Once you locate the App that you wish to quit, just simply swipe it off the screen and it’ll disappear from your home screen.
It’s always a good idea to close your Apps when not in use. It just not saves you battery but also it helps in the efficiency of your iPhone 12.
