With the release of iOS 16, Apple introduced a new feature that allows users to close all open apps at once. This can be done by swiping up from the bottom of the screen and holding until the App Switcher appears. Then, tap on the two overlapping squares in the bottom left corner and select “Close All Apps.”
Closing all open apps can improve your iPhone’s performance and battery life. It can also help to free up memory and make your device run more smoothly. In addition, closing all open apps can help to improve your privacy and security by preventing apps from accessing your data in the background.
