How to Close an App on Any Device: What You Need to Know
Closing an app sounds simple — and usually it is. But depending on your device, operating system, and what you're actually trying to accomplish, "closing an app" can mean several different things. Understanding the difference matters more than most people realize.
What Does "Closing an App" Actually Mean?
When you tap the home button or swipe away from an app, you might assume it's closed. On most modern devices, that's not quite true. There are two distinct states an app can be in after you leave it:
- Background running: The app is suspended but still loaded in memory. It can receive notifications, sync data, and resume instantly.
- Force closed / terminated: The app is fully shut down. It uses no memory or active CPU cycles, and must fully reload when reopened.
Most operating systems — including iOS, Android, Windows, and macOS — are designed to manage background apps automatically. The OS suspends and terminates apps based on available memory, battery state, and usage patterns. You often don't need to manually close anything for your device to perform well.
How to Close Apps on Different Platforms 📱
iOS (iPhone and iPad)
On modern iPhones and iPads:
- Swipe up from the bottom of the screen and pause in the middle (or double-press the Home button on older models) to open the App Switcher.
- Swipe the app card upward to force close it.
Apps running in the background on iOS are heavily restricted by the OS. Apple's memory management is aggressive — most background apps are already frozen and consuming very little. Force-closing is rarely necessary for performance reasons.
Android
The method varies slightly by manufacturer, but the standard approach:
- Tap the Recent Apps button (usually a square icon or a gesture swipe).
- Swipe the app card left or right to dismiss it, or tap "Close All" if available.
You can also force stop an app through Settings → Apps → [App Name] → Force Stop. This is a harder termination that also clears any active processes the app was running.
Windows (PC)
On a Windows computer, closing an app depends on what type it is:
- Desktop apps (Win32): Click the X button in the top-right corner. If an app is unresponsive, open Task Manager (Ctrl + Shift + Esc), find the app under Processes, and click End Task.
- Microsoft Store apps (UWP): These suspend automatically when minimized. Dragging the window to the bottom of the screen or using Task Manager will force close them.
macOS
On a Mac, clicking the red X button hides the window but doesn't quit the app — the app continues running in the background with a dot visible in the Dock.
To fully close an app:
- Press Cmd + Q while the app is active, or
- Right-click the app icon in the Dock and select Quit
For frozen apps, use Force Quit: press Cmd + Option + Esc, select the app, and click Force Quit.
Why You Might — or Might Not — Need to Close Apps
This is where things get more nuanced.
| Scenario | Should You Force Close? |
|---|---|
| App is frozen or unresponsive | ✅ Yes |
| Device running hot or battery draining unusually | ✅ Worth trying |
| You finished using the app normally | ❌ Usually not necessary |
| You want to "save battery" as a habit | ❌ Often counterproductive |
| App needs a fresh start after a crash | ✅ Yes |
Habitually closing every app after use is one of the most persistent tech myths. On iOS and Android especially, force-closing apps can increase battery drain because the device has to reload the full app from storage the next time you open it — rather than resuming a suspended, memory-efficient state.
However, some apps — particularly GPS apps, media players, or poorly optimized third-party apps — do continue consuming resources in the background more than they should. In those cases, closing them makes a real difference.
When Force Closing Actually Helps 🔧
There are legitimate reasons to force close an app:
- The app has crashed or frozen and won't respond to normal inputs
- A background process is misbehaving — draining battery, using excessive data, or running hot
- You need to reset the app state — for example, after changing account settings or permissions
- Privacy or security reasons — you want to ensure no active session remains open
Some apps also need to be fully closed and relaunched to pick up a software update or configuration change.
The Variables That Change the Answer
Whether closing an app matters to you depends on several factors specific to your situation:
- Your OS and its version — iOS 16 handles multitasking very differently than Android 13, and both continue to evolve
- Device age and available RAM — older devices with less memory are more affected by background app behavior
- The specific apps involved — a navigation app, a VPN client, or a streaming service behaves very differently from a note-taking app
- Your usage patterns — someone switching between five apps constantly has different needs than someone who opens one app, uses it, and moves on
- Battery health — a degraded battery is more sensitive to any background activity
There's no single correct behavior here. A power user on a three-year-old Android phone with limited RAM has a very different relationship with app management than someone on a current flagship with 12GB of memory and aggressive battery optimization built in. The right approach depends on what's happening on your specific device — and what problem, if any, you're actually trying to solve.
