iOS - Close Background Apps

Many users are not aware that some apps on your iPhone and iPad can remain active, even after you leave that app or switch to another. Multi-tasking allows your iOS device to do things like let you continue a phone call while you look something up, or continue turn-by-turn navigation while in another app. 

Many apps do not continue to use system resources after you leave them, but in some cases, apps running in the background cause shorter battery life, and others can cause your device to become unstable. It's a good idea to periodically Quit all of the recent apps on your device to maintain optimum performance. Follow these steps: 

1-  From the Home screen, click the Home button twice. This will open a row at the bottom of your device called the recent applications bar. (Just because an app is listed here does not necessarily mean it's still running).

2-  Tap and hold on any one of the apps in the bar until they start to jiggle.

3-  Now tap the red minus icon on each app to close them one-by-one.

4-  When you're done, double-click the Home button to exit the multi-tasking bar.
