If you’ve tried force closing multiple apps from the multitasking bar, you’re probably aware of the frustration that one has to go through to quit all those apps one by one.
This tip, found on reddit, might come in handy for you.
Turns out, you can use multitouch to force quit multiple apps at once from the multitasking tray.
With the iOS device unlocked, double click on the Home button, then touch and hold the app icon until app icons in the multitasking bar begin to jiggle. You can tap on the 
button on multiple app icons to force quit the apps in one go rather than doing it one app at a time.
Although it’s difficult to hit all four fingers at the right spot simultaneously, even closing two apps at once is a lot quicker than quitting one app at a time. The maximum we could manage is quitting three apps at a time, using two thumbs and a finger.
Although it’s widely debated, Apple Geniuses believe that closing these dormant background apps does improve battery life.
We hope this tip helps you!
Note: If you have jailbroken your iOS device then you can use Remove Background SBSettings – a custom toggle for SBSettings that removes all the background apps with just one tap, which is a lot quicker.
