Closing an app on iPhone stops it from running in the background

On an iPhone, closing an app means removing it from your device's active memory so it stops using battery and processing power. Unlike a computer where you close a window and the program shuts down, iPhone apps can run invisibly in the background even after you stop looking at them. Closing an app forces it to stop — at least until you open it again.

The method depends on which iPhone model you have, because older iPhones with a home button work differently from newer ones without one. Both methods take about five seconds once you know the gesture.

Key Takeaways

  • iPhones without a home button use a swipe-up gesture from the bottom of the screen to close apps, while iPhones with a home button use a double-tap and swipe method.
  • Closing an app does not delete it from your phone — it only stops it from running in the background.
  • You do not need to close apps regularly for performance; iOS manages background activity automatically.
  • Closing an app can help if it is frozen, draining battery unusually fast, or behaving strangely.

Closing an app on iPhone 12 and newer (no home button)

If your iPhone has Face ID and no physical home button at the bottom, use the swipe-up gesture. Start at the very bottom of the screen and swipe upward about halfway across the screen, then pause for a moment. You will see all your open apps displayed as cards stacked on top of each other.

Find the app you want to close and swipe it upward off the screen. The app card will disappear, and the app is now closed. If you want to close multiple apps at once, swipe up on each one in turn. To exit this view without closing anything, tap the home indicator (the thin line at the very bottom) or swipe down.

Closing an app on iPhone 11 and older (with home button)

If your iPhone has a home button at the bottom, double-tap it quickly — not a long press, just two quick taps. Your screen will show all your open apps as cards. Swipe upward on the app card you want to close, and it will disappear from the list.

You can close multiple apps by swiping up on each card. When you are done, press the home button once to return to your home screen.

When you actually need to close an app

Closing apps is not something you need to do every day. Modern iPhones are designed to manage background activity on their own — iOS pauses apps that are not in use and only lets them run when they need to. Closing apps constantly will not make your phone faster or save much battery.

Close an app when it is frozen or unresponsive, when it is draining battery much faster than usual, or when it is behaving strangely (showing old data, not loading properly, or crashing repeatedly). Closing and reopening the app often fixes these problems because it clears the app's temporary memory.

The difference between closing and deleting an app

Closing an app stops it from running right now. Deleting an app removes it from your phone entirely — you would have to read it again from the App Store if you wanted it back. Closing does not delete anything; the app stays on your phone and you can open it again whenever you want.

If you want to remove an app permanently, you delete it by pressing and holding the app icon on your home screen, tapping "Remove App," and then tapping "Delete App." Closing is temporary; deleting is permanent.

Why apps keep running in the background

Apps run in the background so they can do things like send you notifications, refresh their content, or play music while you are using a different app. Maps can give you turn-by-turn directions while you listen to a podcast. A messaging app can alert you to new messages even when you are not looking at it. This is a feature, not a bug.

If an app is using too much battery or data in the background, you can limit what it does without closing it. Go to Settings, tap Privacy, then Background App Refresh, and toggle off the apps you do not want running in the background. This is more efficient than closing apps repeatedly.

Frequently Asked Questions

Does closing apps make my iPhone faster?

Not noticeably. iOS manages background apps automatically, so closing them does not free up much processing power. If your phone feels slow, restarting it (turning it off and back on) is more effective than closing individual apps.

Will closing an app delete my data or messages?

No. Closing an app only stops it from running. Your data, messages, photos, and settings stay on your phone. The next time you open the app, everything will be there.

What if I close an app by accident?

Nothing bad happens. Just tap the app icon to open it again. You can close and reopen apps as many times as you want with no consequences.

Should I close apps before updating them?

You do not need to, but it does not hurt. If an app is frozen or not updating properly, closing it first and then opening the App Store to update it can help. Otherwise, the update will work fine with the app running.
