While Apple now allows you to close all the open tabs at one go in iOS 10 Safari, there is still no available tool to kill all your running apps at once on your iPhone. However, if you now have a jailbroken iPhone, there is a simple way you can use to make that possible.
A jailbreak tweak called KillBackground10 allows you to close all your open apps at the same time in iOS 10 with a simple touch of button, eliminating the need to close each of them one at a time. In this guide, we will walk you through the steps to kill all your open apps at once with KillBackground10
Before we begin, you need to jailbreak your device, which may put you at security risks, as jailbreaking makes your device vulnerable to malware infections, data leaks and scams. We recommend you create a full back up of your device in case if something goes wrong during the process.
How to kill all apps at once in iOS 10 with KillBackground10
Step one: You need to download and install KillBackground10 on your device. To do this, head to Cydia, look for the app and download it to your iPhone
Step two: Once you have installed the app, all you need to do is to double press the home button to access the iOS 10 App Switcher
Step three: You will notice that there is a tiny red button in the bottom-right corner of the App Switcher. You simply need to tap on it to close all the open apps on your iPhone.
Aside from the ability to close all open apps at once, KillBackground10 offers a lot of customization options thanks to its configuration pane located in the Settings app. For example, you can enlarge the size of the buttons, exclude some apps that cannot be closed by the tweak and more.
