Apple designed its iPhone software so that you don't have to close an app when you're not using it, since most apps that are not active remain in a suspended state and don't use up any resources or eat up battery.

However, if an iOS app becomes unresponsive, you may need to force quit the app and restart it to get it to work properly again. Here's how you can do that on both older and newer iPhones.

How to Close Apps on iPhones With a Home Button

  1. Double-click the Home button to show your most recently used apps.
  2. Swipe right or left to find the app that you want to close.
  3. Swipe up on the app's preview card to close the app.

How to Close Apps on iPhones With No Home Button

On iPhones without a Home button, a whole different set of gestures are used, one of which involves the App Switcher and the way open apps are found and closed.

  1. On the Home screen of the ‌iPhone‌, or while in an app, swipe up from the bottom of the screen and pause for a moment while still pressing the screen, then let go when the App Switcher appears.
  2. Now swipe left and right through the different app cards to find the app that you want to close.
  3. Use a quick swipe upwards to close the app.

It's worth reiterating that there's generally no need to close your apps to improve performance, as Apple has built-in management systems for dealing with all of the apps that you have open on your device.

According to Apple, force quitting an app will not improve your battery life, and it's possible that doing so can actually drain battery because it causes the ‌‌iPhone‌‌ to load it all over again.
