Maybe an app has locked up and become unresponsive. If you press the home button and re-open the app, it may not fix the issue, in which case you will have to close out of the app. When you press the home button, your app will still be paused in the background, and some apps will still be running, particularly those designed to stream content. In these situations, it may be necessary to force quit the app. Here’s how.
Don’t get caught in the force quitting app trap
There’s a big misconception that closing all of your apps all the time will help your iPhone or iPad run faster. Others think it will help you conserve battery life. We want to make it clear that force quitting apps is only a good thing when an app is locked, unresponsive, or otherwise misbehaving.
If you force quite all your apps constantly, you’re forcing iOS to re-open everything from scratch. The best advice is to let iOS manage the apps. If iOS needs more memory, it will manage that on its own. The mobile operating system also manages background activity, so don’t worry about closing anything unless an app becomes unresponsive.
