How to Close All Background iOS Apps at Once

When you double-tap the home button of your iPad or iPhone, the dock will show a list of all the recently used apps and some of them could still be running in the background.
You tap and hold your finger on the app icon until it begins to jiggle and you can then press the red “minus” sign to close one or more of these background apps. If a particular app is not running, this action will simply remove its listing from the multitasking bar.

Close All Background Apps at Once

If you would like to close all the background apps at once, here’s a free app for iPhone and iPad that can help. You don’t even have to jailbreak your device.
Launch the app and then shake your iPhone / iPad to terminate every single app that could be running in the background. Alternatively, you can just pull and release the processes list (see video) to close all the background running apps at once.
