Why you might want to close an app, and what actually happens

Closing an app on your iPhone means stopping it from running in the background. Most of the time, you do not need to do this — iOS manages memory and battery life automatically, and closed apps do not use power just by sitting there. But closing an app can help if it is freezing, using data when it should not be, or draining your battery faster than normal.

When you close an app, any unsaved work in that app is lost. If you were typing an email draft, taking notes, or editing a photo, closing the app without saving will erase those changes. The app itself stays on your phone — you are not removing it, just stopping it from running.

Key Takeaways

  • Closing an app means stopping it from running in the background, not removing it from your phone.
  • You close apps by swiping up from the bottom of the screen on newer iPhones, or double-tapping the home button on older models.
  • Any unsaved work in the app will be lost when you close it, so save before closing if you have made changes.
  • Most apps do not need to be closed regularly — iOS handles memory and battery automatically.
  • Closing a frozen or misbehaving app can fix problems without restarting your entire phone.

How to close an app on iPhone 11 and newer models

On newer iPhones without a home button, swipe up from the very bottom of the screen and pause for a moment. You will see all your open apps displayed as cards stacked on top of each other. Swipe left or right to find the app you want to close.

Once you see the app card, swipe it upward off the top of the screen. The app will close when ready. You can close multiple apps this way by swiping each one up in turn. When you are done, tap the home screen or swipe down to return to your normal view.

How to close an app on iPhone 8 and older models

On iPhones with a home button, double-tap the home button at the bottom of the phone. This shows all your open apps as cards. Swipe left or right to find the app you want to close.

Once you see the app card, swipe it upward off the top of the screen. The app will close. You can close multiple apps this way. When you are done, press the home button once to return to your home screen.

What to do if an app is frozen or not responding

If an app is frozen and you cannot tap anything inside it, close it using the steps above. The app will stop when ready, and you can open it again fresh. This usually fixes the problem without needing to restart your phone.

If closing the app does not work, or if your entire phone is frozen, restart your iPhone. For newer models without a home button, press and hold the volume up button and the side button together until the power-off slider appears, then drag it to turn off the phone. Wait a few seconds and press the side button again to turn it back on. For older models with a home button, press and hold the top button until the power-off slider appears, then drag it to turn off the phone.

When closing apps actually helps, and when it does not

Closing apps helps when an app is misbehaving, using data in the background when it should not be, or draining your battery noticeably. You can tell an app is draining battery by opening Settings, tapping Battery, then Battery Usage. Apps at the top of that list are using the most power. If one app is much higher than the others, close it and see if battery life improves.

Closing apps does not help with general slowness, storage space, or overall battery life. iOS manages memory automatically — closing an app you are not using does not free up space for other apps to run faster. If your phone is slow or running out of storage, the problem is usually that you have too many large files or apps installed, not that apps are running in the background.

How to prevent apps from running in the background

If an app keeps running in the background and draining battery even after you close it, you can stop it from refreshing in the background. Open Settings, tap General, then Background App Refresh. You will see a list of all your apps. Toggle off the switch next to any app you do not want running in the background.

This is different from closing an app — it means the app will not check for new information (like messages or emails) unless you open it yourself. This saves battery but means you might not see notifications from that app right away.

Frequently Asked Questions

Does closing apps make my iPhone faster?

Not usually. iOS manages memory automatically, so closing apps does not free up space for other apps to run faster. If your phone feels slow, the problem is typically too many large files or apps installed, not apps running in the background. Restarting your phone can help temporarily, but closing individual apps will not.

Will closing an app delete my data?

Closing an app does not delete the app itself or any saved data inside it. When you open the app again, your saved files, photos, and settings will still be there. The only thing you lose is unsaved work — like a draft email or a note you started typing but did not save.

Can I close multiple apps at once?

You can close apps one at a time by swiping each one up, but there is no button to close all apps at once. If you want to close many apps quickly, swipe up from the bottom to see all open apps, then swipe up on each one. It takes a few seconds but is faster than opening and closing them individually.

What is the difference between closing an app and force-closing it?

Closing an app normally (by swiping it up) lets the app shut down cleanly. Force-closing means stopping an app that is frozen and will not respond. On newer iPhones, you force-close by holding your finger on the app card for a moment, then tapping "Remove App" — but usually swiping it up works just as well.
