11. Force quit apps
It’s a myth that force quitting apps will conserve battery life. In fact, Apple says doing so actually wastes more power.
But sometimes an app freezes up and there’s no way to reset with other than to force quit it. On the iPhone 8 and older, force quitting apps was as easy as opening the App Switcher and swiping up on the app.
On iPhone X, this action is a little more complex. First, you need to bring up the App Switcher. Then, you need to long-press on the app until a little red minus symbol appears in the left corner. You can tap on the minus symbol to force quit an app or swipe up on an app.
