How to Close Applications on iPhone: What You Need to Know
Closing apps on an iPhone sounds straightforward — and in many ways it is. But there's a layer of nuance that most users never learn, and it quietly affects how they manage their device every day. Whether you're troubleshooting a frozen app, trying to reclaim memory, or simply tidying up your app switcher, understanding how and when to close apps matters more than just knowing the tap sequence.
How to Close Apps on iPhone: The Basic Method
On any iPhone with Face ID (iPhone X and later), closing an app works like this:
- Swipe up from the bottom of the screen and pause mid-screen — this opens the App Switcher, showing all your open apps as a card stack.
- Swipe left or right to find the app you want to close.
- Swipe the app card upward to dismiss it.
On older iPhones with a Home button (iPhone 8 and earlier), the process is slightly different:
- Double-press the Home button to open the App Switcher.
- Swipe through your app cards.
- Swipe any card upward to close that app.
You can close multiple apps at once by swiping up on several cards simultaneously using different fingers — a small but useful trick most users overlook.
What "Closing" an App Actually Does on iOS 📱
Here's where things get interesting. iOS doesn't work like a traditional desktop operating system. When you leave an app without closing it, iOS automatically suspends it in the background — the app is essentially frozen in place, using minimal to no CPU resources.
This means a "background" app on iPhone is very different from a background app on a PC. It's not actively running, draining your battery, or consuming significant processing power. iOS manages this automatically through a system called app state preservation.
When you force-close an app by swiping it away, you're removing it from this suspended state. The next time you open it, it has to cold launch — reloading entirely from scratch. This can actually make the app feel slower to open than if you'd left it suspended.
When Force-Closing Apps Actually Makes Sense
Despite the above, there are legitimate reasons to close apps:
- An app is frozen or unresponsive. Force-closing and relaunching is the fastest fix.
- An app is behaving strangely — showing outdated data, crashing repeatedly, or displaying errors.
- An app is actively using background resources — some apps, like GPS navigation, music streaming, or fitness trackers, are designed to keep running in the background. These are the exception to the "suspended" rule.
- Privacy. If you've been using a sensitive app on a shared device, clearing it from the App Switcher removes the visual from anyone who opens that view.
| Situation | Force Close Recommended? |
|---|---|
| App is frozen or crashed | ✅ Yes |
| App behaving with errors | ✅ Yes |
| Active navigation/audio running | ✅ Yes |
| App is just sitting in the switcher | ❌ Generally not necessary |
| Trying to save battery | ❌ Rarely helps |
The Battery and Performance Myth 🔋
One of the most persistent misconceptions in iPhone use is that closing all background apps improves battery life and speeds up your phone. Apple has directly addressed this — their own support documentation notes that force-closing apps you aren't using doesn't improve battery life and may actually reduce efficiency.
The reason: iOS is optimized to manage suspended apps efficiently. Constantly killing and relaunching apps forces your processor to do more work, not less. Background app refresh — the feature that allows apps to update content while suspended — can be controlled separately in Settings → General → Background App Refresh, giving you granular control without the need to manually close apps.
That said, if an app has a genuine software bug causing it to consume abnormal battery or data in the background, closing it becomes a relevant troubleshooting step, not a routine habit.
iOS Version and Device Variables That Affect This
How iOS handles app management has evolved significantly across versions. Newer versions of iOS have become increasingly aggressive at optimizing memory management automatically, meaning the system itself may already be closing apps you haven't touched in a while to free up RAM — without you needing to do anything.
The iPhone model also matters:
- Devices with more RAM (newer Pro models, for example) can hold more apps in a suspended state simultaneously, so you're less likely to experience cold launches even after extended time away from an app.
- Older devices with limited RAM may benefit slightly more from manual app management, since iOS may be less able to hold many apps in memory at once.
Your usage patterns matter too. Someone running a single app at a time on a newer device will rarely have a reason to manually close anything. Someone multitasking heavily on an older device, or using resource-intensive apps like video editors or games, may experience a different reality.
Closing Apps Without Touching the Screen
For users with accessibility needs or hardware button limitations, iOS also supports closing apps through AssistiveTouch — a floating on-screen menu that can replicate physical gestures. This is found under Settings → Accessibility → Touch → AssistiveTouch.
Voice control is another option: iOS's built-in Voice Control feature (separate from Siri) allows full gesture-based navigation by voice, including navigating the App Switcher.
What Shapes the Right Approach for You
The mechanics of closing apps on iPhone are fixed — the gestures don't change. But how often you should close apps, and which ones, depends on factors that vary considerably from one user to the next: your iPhone model and its RAM, which iOS version you're running, what kinds of apps you use most, and whether you've noticed specific issues with battery drain or app behavior.
Understanding the system's design is the starting point. Whether routine app-closing makes sense as a habit — or remains something you do only when troubleshooting — is a question your own device and patterns will answer differently than someone else's.
