A new set of gestures were introduced with iPhones without Home buttons, changing how we interacted with them.
Apple introduced a gesture for reaching the App Switcher on devices with a Home button to launch the App Switcher.
How to close out an app on iPhone XS Max,X, XS, XR, 11 Pro, iPhone 11, or 11 Pro Max, 12 Mini, 12 Pro, iPhone 12, or 12 Pro Max
- You can pause and hold the screen while swiping up from the bottom of the screen on the iPhone, or in an app.
- Swipe left and right on the App Switcher card to find the app you want to close.
- Sliding upwards closes the app.
When you use this gesture, you close an app and exit. This is useful if you need to restart an app for some reason. As Apple has built-in management systems for all your apps, you don’t need to close them to improve performance.
Applications that aren’t active are suspended and aren’t using any resources, but some can run in the background for a period of time if the background refresh feature is enabled.
Apple claims force-quitting will not improve battery life, and it may even drain battery because the iPhone has to start loading the app all over again.
