Force-quitting shouldn't be an all-the-time thing, but can occasionally help when something goes wrong.

Some apps—especially the Facebook, Skypes, and big media apps of the world—don't always behave well on iPhone, iPod touch, or iPad. When and if that happens, you can try "force quitting" them. iOS 9 almost always handles pausing and shutting down apps just fine. So, force quitting isn't something you should do often, because re-launching it again from scratch will consume more power and take more time as it updates in the foreground, but it is something you should know how to do for when you need it.

How to force quit an app on iOS 9 for iPhone or iPad

While the design of iOS 9's fast app switcher and task manager has changed, the way it works is the same as iOS 7 and iOS 8.

  1. Double click the Home button (or 3D Touch press the left side of the screen on iPhone 6s) to bring up the fast app switcher.
  2. Swipe to the app you want to force quit.
  3. Touch the app card and flick it up and off the screen.


I'll confess to force-quitting Facebook and Skype semi-regularly. That's because, historically, they've been offensively bad at power management. I used to force-quit Maps and Google Maps after turn-by-turn navigation but they've both gotten much better at powering down over the last year or two.

How to force quit three apps at once on iOS 9 for iPhone or iPad

You almost never want to kill more than one app at a time. It will inevitably decrease performance and battery life since you're killing state and forcing everything to start over. If you can't find the source of a rogue process or are otherwise pressed for time and just need everything to stop, however, it's again something you should know how to do. Even if you don't ever do it.

  1. Double click the Home button (or 3D Touch press the left side of the screen on iPhone 6s) to bring up the fast app switcher.
  2. Swipe to the app you want to force quit.
  3. Touch the app card and flick it up and off the screen.


Because iOS 9 shows a fourth, blurred out, app all the way to the left, you can try and do four at a time. I can't say I've gotten it to work, but I will say I keep trying. Sometimes.

How to force quit an app without using the fast app switcher

If for some reason you don't want to use the fast app switcher interface to kill an app, you can still use the old fashioned way. (Which you might be familiar with from the Apple Watch.)

  1. Go to the app you want to force quit.
  2. Hold down the On/Off button until the "slide to power off" screen appears.
  3. Hold down the Home button until you're dropped back onto the Home screen.


There's a subtle difference in how the system tracks this version of force quitting, but the result is the same.
