The fastest way to close an app on iPhone

To close an app on iPhone, swipe up from the bottom of the screen to open the app switcher, then swipe up on the app card you want to close. That's it — the app shuts down when ready. On newer iPhones with Face ID (iPhone X and later), this swipe starts from the very bottom edge. On older iPhones with a home button, double-tap the home button instead to see all open apps, then swipe up on the one you want to close.

You don't need to close apps to save battery or improve speed — iOS manages background activity automatically. But closing an app is useful when it's frozen, behaving strangely, or draining battery visibly. Closing and reopening often fixes glitches that a straightforward restart won't.

Key Takeaways

  • Swipe up from the bottom of the screen (or double-tap the home button on older iPhones) to see all open apps at once.
  • Swipe up on any app card to close it — the app stops running when ready and clears from memory.
  • Closing apps is not necessary for battery life or performance, but it fixes frozen or misbehaving apps quickly.
  • If an app won't close using the normal method, force-quit it by holding the power button and volume button together until the shutdown screen appears, then release and wait for the app to close.

Closing apps on iPhone with Face ID (iPhone X and newer)

On iPhones without a home button, the app switcher is accessed from the bottom of the screen. Place your finger at the very bottom edge of the screen and swipe upward in one smooth motion. You'll see all your open apps displayed as cards stacked on top of each other.

Once the app switcher is open, find the app you want to close. Swipe up on its card — you don't need to swipe hard, just a normal upward flick. The card will disappear and the app closes. You can close multiple apps in one session by swiping up on each one.

Closing apps on iPhone with a home button (iPhone 8 and earlier)

On older iPhones, double-tap the home button (the physical button at the bottom of the phone) to open the app switcher. You'll see your open apps displayed as cards. Swipe left or right to find the app you want to close.

Once you locate it, swipe up on the app card. The app closes and the card disappears. You can continue swiping through and closing other apps the same way. When you're done, press the home button once to return to your home screen.

Force-quitting an app that won't respond

If an app is completely frozen and won't close using the normal swipe method, you can force-quit it. On iPhones with Face ID, hold down the power button and the volume-down button at the same time. Keep holding both buttons until you see the "slide to power off" screen appear — this takes about 3 seconds.

Release both buttons and wait. The frozen app will close automatically, and your phone will return to normal. You don't need to actually power off your phone; the force-quit happens as soon as you release the buttons. On iPhones with a home button, hold the top button (or side button on iPhone 6s and earlier) until the power-off screen appears, then release.

When to close apps versus when to leave them open

Modern iPhones are designed to manage apps running in the background without draining significant battery or slowing down your phone. Closing apps constantly is unnecessary and won't improve performance. iOS automatically pauses background activity for apps you're not using and resumes it when you open them again.

Close an app when it's frozen, crashing repeatedly, or using battery visibly in Settings. You can check which apps are draining battery by going to Settings, then Battery, then Battery Usage. If one app shows unusually high usage, close it and reopen it to reset its behavior. Otherwise, let iOS manage your open apps on its own.

Restarting your phone instead of closing individual apps

If multiple apps are misbehaving or your phone feels sluggish, restarting is often more effective than closing apps one at a time. On iPhones with Face ID, hold the power button and volume-down button until the power-off slider appears, then drag the slider to power off. Wait 10 seconds, then hold the power button again until the Apple logo appears.

On iPhones with a home button, hold the top button until the power-off slider appears, then drag it. Wait 10 seconds and hold the button again to restart. A full restart clears temporary files and resets all background processes at once, which fixes most performance issues faster than closing individual apps.

Frequently Asked Questions

Does closing apps save battery?

No. iOS pauses apps running in the background automatically, so they use minimal battery. Closing apps constantly won't extend battery life. If one specific app is draining battery visibly, close it and reopen it to reset its behavior, but closing apps in general is not necessary.

What happens to my data when I close an app?

Closing an app does not delete your data. Saved files, photos, messages, and settings stay on your phone. When you reopen the app, your data is still there. The app straightforward stops running in memory until you open it again.

Can I close multiple apps at once?

You can close them one at a time by swiping up on each card in the app switcher, but there's no button to close all apps simultaneously. If you want to reset everything at once, restart your phone instead — it's faster and more thorough.

Why does my app keep crashing even after I close it?

If closing and reopening doesn't fix a crashing app, try restarting your phone. If the app still crashes, check the App Store for updates — outdated apps crash more often. If updates don't help, uninstall and reinstall the app from the App Store.
