If your device feels sluggish or you're trying to free up memory, closing apps properly matters—but the right way depends on what device you're using and what you're trying to accomplish. Let's walk through what actually happens when you close an app, when it's worth doing, and the clearest methods for different situations.
When you close an app, you're telling your device to stop running that program and clear it from active memory. This is different from deleting an app, which removes it entirely from your device.
Closing an app can:
However, simply closing an app doesn't delete your data within it—your photos, messages, saved information, and login details stay on your device.
Not every app needs to be closed constantly. The impact depends on:
Your device's age and available memory. Newer phones and computers with plenty of RAM can usually run several apps simultaneously without noticeable slowdown. Older devices or those running low on storage may benefit more from regular closing.
What the app does in the background. Some apps quietly sync data, check for notifications, or use location services even when you're not actively using them. Closing these can reduce battery drain and improve overall responsiveness.
Whether an app is malfunctioning. A frozen or crashing app sometimes needs to be force-closed and relaunched to work properly again.
How many apps you typically have open. If you habitually keep 20+ apps running simultaneously, closing unused ones may noticeably improve speed.
Standard close (swipe up): Swipe up from the bottom of the screen, hold briefly, then release. This removes the app from recent memory. (Gesture varies slightly by iOS version—check your device settings if you're unsure.)
Force close: If an app is frozen, press and hold the app icon on your home screen, then select "Remove App" → "Remove from Home Screen," or use Settings > General > iPhone Storage to offload the app temporarily.
Swipe to close: Swipe up from the bottom to view recent apps, then swipe the app card upward to close it.
Close via Settings: Go to Settings > Apps, select the app, and tap "Force Stop" if it's unresponsive.
Task switcher: Hold the navigation buttons or swipe left/right through your recent apps and close individually.
Click the X button: Close the window in the top-right corner. This removes the app from your screen and typically from active memory.
Task Manager: Press Ctrl + Shift + Esc, find the app in the list, and click "End Task" to force-close if it's frozen.
Alt + F4: A keyboard shortcut to close the current window quickly.
Red close button: Click the red button in the top-left corner of the app window.
Command + Q: Quits the current app entirely (different from simply closing the window).
Force Quit: Press Command + Option + Esc, select the app, and click "Force Quit" for frozen applications.
Modern devices are designed to manage multiple apps efficiently. Many experts recommend not obsessively closing apps because:
Rather than closing every app after use, consider:
The speed you feel on your device depends less on religiously closing apps and more on how much storage you have free, how many apps you've installed, and how recent your device is. Closing apps is a useful tool for specific problems, not a daily maintenance habit most people need.
