The quickest way to close an app depends on your iPhone model

On newer iPhones with Face ID (iPhone X and later), swipe up from the bottom of the screen to the middle, pause for a moment, then release. This brings up the app switcher — a card-like view of all your open apps. Find the app you want to close, swipe up on its card, and it disappears from memory.

On older iPhones with a home button (iPhone 8 and earlier), double-tap the home button instead. The app switcher appears the same way. Swipe up on the app card to close it.

You do not need to close apps to save battery or improve performance — iOS manages background activity automatically. But closing an app can help if it is misbehaving, using too much data, or if you want to start fresh the next time you open it.

Key Takeaways

  • On Face ID iPhones, swipe up from the bottom and pause; on home button iPhones, double-tap the home button to open the app switcher.
  • Once the app switcher is open, swipe up on any app card to close it completely.
  • Closing an app does not free up storage space or significantly extend battery life — iOS handles background processes on its own.
  • Force-closing a frozen or unresponsive app is different from normal closing and requires holding the power button or using Settings.

How to open the app switcher on Face ID iPhones

Start at the very bottom edge of your screen. Place your finger there and swipe upward in one smooth motion, stopping about halfway up the screen. You should see a pause — do not release yet. Wait a half-second, then let go. The app switcher appears as a stack of overlapping cards, each one representing an open app.

If you swipe too quickly without pausing, you may just return to the home screen instead. The pause is the key difference between opening the switcher and going home. Once you see the cards, you are in the right place.

How to open the app switcher on home button iPhones

Press the home button twice in quick succession — not a long press, just two taps. The app switcher opens immediately, showing your open apps as cards. The home button is the circular button at the bottom center of your screen.

If you hold the home button too long, Siri may open instead. Keep the presses quick and light to avoid this.

Closing an app from the switcher

Once you see the app cards, find the one you want to close. Swipe upward on that card — place your finger on it and drag it toward the top of the screen. The card flies off the screen and the app closes. You can close multiple apps this way by swiping up on each one.

The app is now fully closed and will not run in the background. The next time you open it, it will start fresh.

When to close an app versus force-closing it

Normal closing (the method above) works for apps that are running but not causing problems. Force-closing is different — it is what you do when an app is frozen, not responding, or crashing repeatedly.

To force-close an app on a Face ID iPhone, hold down the power button and either volume button together until the power-off slider appears. Release the buttons, then hold the power button alone until the screen goes black. Wait a few seconds, then press the power button again to turn the phone back on. The app will be completely shut down.

On a home button iPhone, hold the top (or side) button until the power-off slider appears, then release. Hold the home button until the screen goes black. Wait a few seconds and press the top button to restart. This force-closes any frozen app.

Alternatively, you can force-close an app through Settings without restarting your phone. Go to Settings, tap General, then iPhone Storage. Find the app in the list, tap it, and tap Offload App. This removes the app from memory without deleting it — you can reinstall it from the App Store later.

Why closing an app does not always fix problems

If an app keeps crashing or freezing even after you close it normally, force-closing is more effective. Normal closing may not fully clear the app's data from memory, especially if something went wrong before you closed it.

If force-closing does not help, the next step is to delete and reinstall the app. Open the App Store, search for the app, and tap Get to reinstall it. This clears out any corrupted files that closing alone cannot fix.

Frequently Asked Questions

Does closing apps save battery?

Not significantly. iOS pauses background activity for closed apps, but the battery savings are minimal because iOS already limits what closed apps can do. Closing an app manually does not extend your battery life in any noticeable way.

Will closing an app delete my data?

No. Closing an app removes it from active memory but does not delete any saved data, photos, messages, or settings within that app. The next time you open it, everything will be there.

What if I cannot swipe up from the bottom on my iPhone?

Make sure you are starting from the very bottom edge of the screen, not from the middle. On some iPhones, the gesture area is only about half an inch tall. If you still have trouble, try double-tapping the home button instead (if your phone has one), or restart your iPhone and try again.

Can I close all apps at once?

No, iOS does not have a "close all" button. You have to swipe up on each app card individually. However, you do not need to close all apps — closing only the ones that are misbehaving is usually enough.

Is force-closing the same as deleting an app?

No. Force-closing shuts down the app temporarily but leaves it installed on your phone. Deleting an app removes it entirely from your device. You can reinstall a deleted app from the App Store, but you cannot reinstall a force-closed app — it is still there.
