How to close apps on the iPhone X
It’s a common misconception that closing out apps on your iPhone helps extend battery life. This isn’t really true—iOS suspends inactive background applications qui5te effectively. Re-starting apps from scratch takes more time and can result in shorter battery life than simply un-suspending them.
But apps aren’t always perfectly well behaved. Sometimes they freeze or the interface gets corrupted, and you need to start over fresh. Those sorts of situations are the only times you should really close apps.
With no home button on the iPhone X, how do you do it? Simple:
1. Bring up your list of all apps by swiping up from the bottom of the screen and pausing for a second. You’ll see cards for all your apps pop in.
