Is there an app killer for iPhone? Best way to force stop apps

Tim Vickers

When you tap on the home button twice on your iPhone, you will see a list of your recently used apps. Depending on the app, it could be running in the background or on standby mode.

You can manage the apps hidden in the dock by removing them manually. This sends the applications to a closed state. But is there an app killer for iPhone that allows you to close all background apps at once?

You can use an app killer to remove apps running in the background or on standby mode. An app killer will remove all the applications you are not using, and free some memory on your device.

Note that these apps will also stop streaming apps and files you are currently downloading in the background.

Whenever you close apps on iPhone, they save your information and go into standby mode in the dock. When you open the app again, it will load from where you left.

An app killer, on the other hand, will close the app completely. That means the application will load afresh when you re-open it.

Should I kill apps on iPhone?

Many people believe killing or quitting apps running in the background can help them save battery life even when they are not using the applications.

But that is not correct. Instead, killing all apps at once can reduce battery life.

You should only force stop an app on iPhone if it is unresponsive. When your recently used applications appear in the dock, they are not open. Instead, they are in standby mode.

Standby mode helps you to navigate between apps and multitask. Once you open the apps, they will begin from where you left off.

But if you close them down, they will have to load again. The whole process of loading takes too much memory and can drain the battery.

How do you kill an app on your iPhone?

You can kill an app on your iPhone without using an app killer using the steps below:

  • If you are using iPhone X and newer, swipe up halfway on the screen and pause. You will see the multitasking view. Then, swipe the app up and off the top to close it.
  • If you are using iPhone 8 and 7, double-tap the Home button. Then, slide the apps to find the one to kill. Swipe the app up and off the top to close it.
  • For iOS 6 and below, double-tap the Home button. You will then have to slide all apps to locate the one to close. Tap and hold the app and then tap the red badge to kill it.
