You normally do not need to close iPhone apps after using them. iOS manages suspended apps automatically, and repeatedly force-closing everything does not generally improve battery life. Close an app when it is frozen or behaving incorrectly.
Close an app on an iPhone 13
- Swipe up from the bottom edge of the screen and pause near the middle.
- When the App Switcher appears, swipe left or right to find the app.
- Swipe upward on the app’s preview to close it.
- Tap another app or the background to leave the App Switcher.
You can use more than one finger to swipe away multiple app previews, but there is no built-in Close All button.
If an app keeps freezing after you close and reopen it, check the App Store for an update and make sure iOS is current. Restarting the iPhone can also help with a temporary problem. Deleting and reinstalling the app is a later troubleshooting step because locally stored app data may be removed unless it is synced or backed up.
Closing an app from the App Switcher is different from deleting it. The app remains installed and can be opened normally from the Home Screen or App Library.
