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. This works on all iPhones with Face ID (iPhone X and newer). On older iPhones with a home button, double-tap the home button instead to open the switcher, then swipe up on the app.

The app closes immediately and returns you to the home screen or the app you were using before. You do not need to confirm the action — the swipe itself closes the app.

Most of the time, you do not need to manually close apps at all. iOS manages background activity automatically, pausing apps when you switch away and stopping them from draining battery or data. Closing an app is useful mainly when an app is frozen, misbehaving, or you want to force it to reload from scratch the next time you open it.

Key Takeaways

  • Swipe up from the bottom of the screen on Face ID iPhones, or double-tap the home button on older models, to see all open apps.
  • Swipe up on any app card to close it; the app closes instantly without a confirmation prompt.
  • Closing apps does not save battery on modern iPhones because iOS pauses background activity automatically.
  • Close an app if it is frozen, crashing, or you need it to start fresh the next time you open it.

How to close multiple apps at once

If you want to close several apps quickly, open the app switcher the same way — swipe up from the bottom on Face ID iPhones, or double-tap the home button on older models. Then swipe up on each app card one at a time. There is no way to select multiple apps and close them all in one gesture.

You can also close all apps by going to Settings > General > iPhone Storage, finding an app, tapping it, and selecting "Offload App" or "Delete App". Offloading removes the app but keeps your data; deleting removes both. This is different from closing an app and is mainly useful if you want to free up storage space or remove an app you do not use.

When an app won't close

If an app does not close when you swipe up, or if the swipe does not open the app switcher, force-restart your iPhone. The method depends on your model. On iPhone X and newer, press and quickly release the volume up button, press and quickly release the volume down button, then press and hold the side button until the power-off slider appears. On iPhone 8 and earlier, press and hold the top (or side) button and the volume down button together until the slider appears.

After the slider appears, drag it to turn off your iPhone, wait a few seconds, then press the power button again to turn it back on. This clears the app from memory and usually fixes freezing or unresponsive behavior.

Closing apps versus clearing cache and data

Closing an app and clearing its cache or data are two different things. Closing an app simply stops it from running. Clearing cache removes temporary files the app stored to load faster next time; clearing data removes saved settings, login information, and other stored content.

To clear an app's cache or data on iPhone, go to Settings > General > iPhone Storage, tap the app, and select "Offload App" (which keeps data) or "Delete App" (which removes everything). You cannot selectively clear only the cache on iPhone the way you can on Android — you either keep the data or delete it all.

Why closing apps does not improve battery life

On modern iPhones, closing apps does not meaningfully extend battery life. iOS automatically pauses apps running in the background and stops them from using CPU, network, or location services unless you have given them permission to do so. An app sitting in the app switcher uses almost no power.

The exception is an app that is actively misbehaving — one that is stuck using location, playing audio, or running a background task even though you are not using it. If you notice an app draining battery, close it and check Settings > Privacy to see what permissions it has. You can revoke location, microphone, camera, or other access on a per-app basis without closing the app.

Closing apps on different iPhone models

The method to close apps changed with the introduction of Face ID. On iPhone X, 11, 12, 13, 14, 15, and 16, swipe up from the very bottom of the screen to open the app switcher. On iPhone 8 and earlier, double-tap the home button. On iPhone SE (1st generation), which has a home button, also double-tap the home button.

After the app switcher opens, the action is the same on all models: swipe up on the app card you want to close. The card moves up and off the screen, and the app closes.

Frequently Asked Questions

Does closing apps on iPhone save battery?

No. iOS pauses background activity automatically, so apps in the switcher use almost no power. Close an app only if it is misbehaving or frozen, not to save battery. If an app is draining battery, check Settings > Privacy to see what permissions it has and revoke access if needed.

What happens to my data when I close an app?

Closing an app does not delete any data. Your saved settings, login information, photos, and other content stay on your phone. The next time you open the app, it will load your data as usual. If you want to remove an app's data, you must delete or offload the app itself in Settings.

Can I close all apps at once?

No. You must swipe up on each app card individually in the app switcher. There is no bulk close option. If you want to close many apps, open the switcher and swipe up on each one in sequence.

Why is my app still running after I closed it?

If an app appears in the switcher again after you close it, it may have been relaunched by iOS or another app, or it may be a background service that restarts automatically. Force-restart your iPhone by holding the power button and volume buttons, which will clear all apps from memory and stop background processes.

Is there a difference between closing an app and swiping it away?

No. Swiping up on an app card in the switcher is the same as closing it. Both actions stop the app from running. The terms are used interchangeably.
