How to Close All Open Apps on iPhone: What You Need to Know

Closing apps on an iPhone seems straightforward — swipe up, they're gone. But there's a lot more happening under the hood than most users realize, and whether or not closing your apps actually does what you think it does depends heavily on your iPhone model, iOS version, and what you're trying to achieve.

What "Open" Apps Actually Means on iOS

Before diving into the steps, it helps to understand what iOS is actually doing when apps appear in your app switcher. iOS does not keep most apps actively running in the background the way a desktop operating system does. When you leave an app, iOS typically suspends it — freezing it in memory so it can reload quickly when you return.

What you see in the App Switcher (that grid of app previews) is not a list of apps consuming your battery or processor. It's closer to a history of recently used apps. Some apps do run limited background tasks — location services, music playback, push notifications, background app refresh — but these are governed by iOS permissions, not by whether the app appears in the switcher.

This distinction matters when deciding whether force-closing apps is actually useful for your situation.

How to Close Apps on iPhone: Step-by-Step

The method varies slightly depending on your iPhone model.

iPhones With Face ID (iPhone X and Later)

  1. Swipe up from the bottom edge of the screen and pause in the middle — this opens the App Switcher.
  2. Swipe left or right to browse open apps.
  3. Swipe up on any app card to close it.
  4. To close multiple apps at once, use two or three fingers to swipe up on several app cards simultaneously.

iPhones With a Home Button (iPhone 8 and Earlier)

  1. Double-press the Home button to open the App Switcher.
  2. Swipe left or right to find apps.
  3. Swipe up on an app card to close it.
  4. You can use multiple fingers to swipe up on several cards at the same time.

⚠️ There is no built-in iOS option to close all apps at once with a single tap. Every app must be dismissed individually or in small batches using the multi-finger swipe method.

Does Closing All Apps Actually Help Performance?

This is where user expectations often diverge from reality. The common assumption is that closing background apps frees up memory and improves battery life. Apple's own guidance has historically pushed back on this idea.

Here's what's generally true:

  • Suspended apps use minimal RAM and are not drawing on CPU resources.
  • Force-closing an app means iOS has to fully reload it from scratch next time you open it, which can increase battery and processor usage temporarily.
  • Background App Refresh — the setting that allows apps to fetch new data while not in use — can be managed independently in Settings > General > Background App Refresh, regardless of whether apps are "closed."

That said, there are legitimate scenarios where closing apps makes sense:

SituationClosing Apps Likely Helps
An app is frozen or behaving unexpectedly✅ Yes
You want to fully restart an app to clear a glitch✅ Yes
Your iPhone feels sluggish and you suspect a specific app✅ Yes
You want to improve general battery life❌ Generally not
You want to free up RAM for better speed❌ iOS manages this automatically

Variables That Change the Equation 📱

How useful it is to close apps — and how often you'd want to — depends on several factors specific to your setup.

iOS version plays a role. Apple has refined background process management across major iOS releases. How apps are suspended, what background activity is permitted, and how aggressively iOS clears memory has evolved with each update. What was true in iOS 14 may behave differently in later versions.

Device age and available RAM matter. Older iPhones with less RAM may experience more frequent app reloads regardless of whether you manually close apps — iOS will evict apps from memory on its own when resources are needed. Newer devices with more RAM tend to keep more apps suspended without issue.

Which apps are running background tasks is specific to your installed apps and their permissions. An app with location access set to "Always" behaves differently from one with "While Using." A streaming music app running in the background is genuinely active. A notes app is almost certainly not.

Your usage patterns determine whether the App Switcher becomes cluttered with dozens of apps or stays relatively lean. Heavy multitaskers who jump between many apps throughout the day are working with a different situation than someone who primarily uses two or three apps.

What About Battery Drain From Background Apps?

If battery life is your concern, the more targeted approach is usually:

  • Reviewing Settings > Battery to see which apps are consuming the most power and over what time period.
  • Adjusting location permissions for apps that don't need constant access.
  • Turning off Background App Refresh for specific apps rather than all of them.
  • Checking for apps that show unusually high background activity.

These settings give you surgical control over what's actually affecting your battery — rather than routinely closing the App Switcher as a blanket fix.

The Difference Between Closing and Uninstalling

It's worth noting that closing an app in the switcher and deleting an app are entirely different actions. Closing removes it from the recent apps list and ends any suspended state. Deleting removes the app and its data from your device entirely. If storage is your concern rather than performance, the App Switcher isn't the right tool for that job.

How useful a habit of closing apps turns out to be depends on which of these goals you're working toward — and on the specific combination of iPhone model, iOS version, apps installed, and permissions you've granted them.
