The fastest way to close all apps at once
iPhone does not have a single button to close every open app at the same time. Instead, you close apps one by one using the app switcher, or you can restart your phone to force all apps closed. The app switcher is the faster method if you have only a few apps running. A restart is more thorough and clears your phone's memory completely, which can solve performance problems.
Most people do not need to close apps regularly. iOS manages background activity automatically — apps do not drain your battery just by being open. However, closing apps can help if your phone is running slowly, an app is frozen, or you want to clear your recent activity.
Key Takeaways
- Open the app switcher by swiping up from the bottom of the screen (or swiping down from the top-right corner on older iPhones), then swipe up on each app card to close it individually.
- Restarting your iPhone forces all apps closed and clears temporary memory, which is faster than closing apps one by one if you have many open.
- Closing apps does not significantly improve battery life on modern iPhones because iOS suspends background activity automatically.
- Force-closing a single frozen app is different from closing all apps — hold the app icon and tap "Remove App" or swipe up on its card in the app switcher.
How to close apps using the app switcher
The app switcher shows all your open apps as cards on the screen. On iPhones with Face ID (iPhone X and newer), swipe up from the bottom of the screen and pause in the middle. On iPhones with a home button (iPhone 8 and earlier), double-tap the home button instead.
Once the app switcher is open, you will see cards for each open app. Swipe up on any card to close that app. You can close multiple apps in a row by swiping up on each one. There is no limit to how many you can close this way, but it takes longer if you have many apps open.
If you want to close all apps but do not want to swipe up on each one individually, restarting your phone is faster. A restart closes every app and clears your phone's temporary memory in one action.
How to restart your iPhone to close all apps
Restarting your iPhone forces all open apps to close and clears the phone's working memory. This is the fastest way to close everything at once, especially if you have many apps running.
On iPhones with Face ID, press and hold the side button and either volume button until the power-off slider appears. Drag the slider to turn off your phone. Wait a few seconds, then press and hold the side button again until the Apple logo appears. On iPhones with a home button, press and hold the top (or side) button until the power-off slider appears, then follow the same steps.
Your phone will restart and all apps will be closed. This process takes about one to two minutes from start to finish. After restart, your phone will be faster because the temporary memory is cleared.
When you actually need to close apps
Modern iPhones suspend apps automatically when you switch away from them, so they do not drain your battery or slow down your phone just by being open. You do not need to close apps as a daily habit.
Close apps in these situations: when an app is frozen or not responding, when your phone is running noticeably slower than usual, when you want to clear your recent activity before handing your phone to someone else, or when an app is using location or microphone in the background and you want to stop it immediately.
If an app crashes or stops responding, closing it and reopening it usually fixes the problem. If your phone is slow, a restart clears temporary files and memory more effectively than closing individual apps.
How to force-close a single frozen app
If one app is frozen or not responding, you can force it closed without closing everything else. Open the app switcher, find the frozen app's card, and swipe up on it. The app will close immediately.
On older iPhones, you can also force-close an app by holding its icon on the home screen, tapping "Remove App," and then tapping "Remove from Home Screen" (this removes it from your home screen but does not uninstall it). However, using the app switcher is faster and does not change your home screen layout.
The difference between closing and uninstalling apps
Closing an app stops it from running but keeps it on your phone. You can open it again whenever you want. Uninstalling an app removes it completely from your phone, and you would need to download it again from the App Store if you want it back.
Closing apps does not free up storage space. If you want to free up space on your phone, you need to uninstall apps you no longer use. You can uninstall an app by holding its icon on the home screen, tapping "Remove App," and then tapping "Remove from Home Screen" and "Delete App."
Why your iPhone might feel slow even after closing apps
If your phone is still slow after closing apps or restarting, the problem is usually not the apps themselves. Low storage space, too many background processes, or an outdated iOS version can all slow down your phone more than open apps do.
Check your storage by going to Settings, tapping General, and then Storage. If you have less than 1 GB free, delete photos, videos, or apps you do not use. You can also check for iOS updates by going to Settings, tapping General, and then Software Update. Installing the latest version can improve performance.
Frequently Asked Questions
Does closing apps save battery on iPhone?
No. iOS automatically suspends apps when you switch away from them, so they do not use battery power. Closing apps does not extend your battery life. If your battery drains quickly, the problem is usually a setting like high screen brightness, location services, or background app refresh — not open apps.
Can I close all apps at once without restarting?
No. There is no single gesture or button to close all apps at once. You can either swipe up on each app card in the app switcher individually, or restart your phone to force all apps closed. Restarting is faster if you have many apps open.
What happens to my data if I close an app?
Closing an app does not delete your data. Any information the app saved — messages, photos, notes — stays on your phone. When you open the app again, your data will be there. The only exception is unsaved work within the app, which will be lost if you close it without saving first.
Is it bad to leave apps open all the time?
No. Leaving apps open does not harm your iPhone or wear out the battery faster. iOS is designed to manage open apps efficiently. You only need to close apps if one is frozen, your phone is running slowly, or you want to clear your recent activity.
