How to Close Open Apps on iPhone: A Complete Guide
Managing the apps running on your iPhone is one of those everyday tasks that sounds simple but comes with a surprising amount of nuance. Whether you're trying to free up your screen, troubleshoot a frozen app, or just tidy things up, knowing how to close open apps — and when it actually matters — is genuinely useful knowledge.
What "Open Apps" Actually Means on iPhone
When you press the Home button or swipe up to leave an app, iOS doesn't fully close it. Instead, the app moves into a suspended state in the background. It's still visible in your app switcher, but it's largely paused — not actively using your CPU or draining your battery in most cases.
This is an important distinction. The apps you see in your app switcher aren't necessarily running; many are simply cached in memory so they reload faster when you return to them. iOS manages this automatically, offloading apps from memory as needed.
That said, there are real situations where manually closing an app makes sense: when an app has frozen, is behaving unexpectedly, or is actively running a background process you want to stop.
How to Close Apps on iPhone: Step-by-Step
The method you use depends on whether your iPhone has a Home button or uses Face ID (no Home button).
iPhones Without a Home Button (Face ID Models)
These include iPhone X and all later models — the XS, XR, 11, 12, 13, 14, 15 series, and beyond.
- Swipe up from the bottom edge of the screen and pause in the middle — this opens the App Switcher.
- You'll see a horizontal carousel of app preview cards.
- Swipe up on any app card to close it.
- To close multiple apps, use multiple fingers simultaneously and swipe up on several cards at once.
iPhones With a Home Button (Touch ID Models)
These include iPhone SE (1st, 2nd, and 3rd generation), iPhone 8, iPhone 7, iPhone 6s, and earlier.
- Double-press the Home button to open the App Switcher.
- Swipe left or right through the app preview cards.
- Swipe up on any card to close that app.
- Press the Home button once to return to your home screen.
📱 The swipe-up gesture is consistent across both device types — the only difference is how you open the App Switcher in the first place.
When Closing Apps Actually Helps
This is where user situations start to diverge significantly.
Good reasons to force-close an app:
- The app has frozen or crashed and won't respond
- An app is playing audio or using GPS in the background when you don't want it to
- You're troubleshooting an app that's behaving incorrectly and want a fresh start
- A navigation or fitness app is tracking data you no longer need
Less convincing reasons people commonly cite:
- "Closing apps saves battery" — iOS is designed to suspend background apps efficiently; force-closing and reopening apps can actually use more battery than leaving them in cache
- "It frees up RAM" — Again, iOS actively manages memory; it evicts cached apps automatically when new ones need resources
- "It makes the phone faster" — For most apps, reopening from cache is faster than a cold launch
The gap between what people believe closing apps does and what it actually does is one of the most persistent myths in iPhone use. Apple's own engineers have noted that regularly closing apps from the switcher is generally unnecessary for performance.
Variables That Change the Equation
Whether force-closing apps is a useful habit or unnecessary effort depends on several factors:
| Variable | How It Affects App Management |
|---|---|
| iOS version | Newer iOS versions handle background app management more efficiently |
| iPhone model/RAM | Older iPhones with less RAM cycle apps out of memory more aggressively |
| App type | Background-active apps (music, navigation, fitness tracking) behave differently than standard apps |
| App health | A buggy or memory-leaking app may genuinely benefit from a force-close |
| Usage patterns | Power users switching between many apps frequently may notice different behavior than casual users |
Older iPhones — particularly models with 2GB of RAM or less — may experience more noticeable slowdowns when memory pressure is high. On those devices, closing unused apps before launching something demanding (like a game or video editor) can make a practical difference.
Newer iPhones with larger RAM pools and more sophisticated iOS memory management rarely need manual intervention.
A Note on Background App Refresh
Separate from force-closing, Background App Refresh controls whether apps can update their content while sitting in the background. You can manage this individually per app in:
Settings → General → Background App Refresh
Turning this off for apps that don't need it (social media, news apps, etc.) has a more meaningful impact on battery life than manually closing apps from the switcher.
What You See in the App Switcher Isn't Always What You Think
One source of confusion: apps in the App Switcher aren't sorted by "currently running." They're sorted by most recently used. An app you opened three days ago may still appear there even though iOS has long since cleared it from active memory.
This means the number of apps visible in your switcher isn't a reliable indicator of anything — not battery drain, not memory use, not performance impact. ⚡
How useful it is to regularly clear your App Switcher ultimately comes down to your specific iPhone model, which version of iOS you're running, the kinds of apps you use most, and whether you're noticing actual performance issues — or just following a habit that made more sense on older hardware.
