What closing an process means
Closing an process means shutting down a program completely so it stops running on your device. When you close an app, it stops using your device's memory and battery power. The difference between closing an app and just switching away from it matters: switching to another app leaves the first one running in the background, while closing it stops it entirely.
Most people confuse closing with minimizing. When you minimize a window, you hide it from view but the program keeps running. When you close it, the program shuts down. On phones and tablets, this distinction is even more important because background apps drain your battery faster and can slow down your device.
Key Takeaways
- Closing an process completely stops it from running, while minimizing just hides it from view.
- On Windows, click the X button in the top right corner of the window to close most applications.
- On Mac, click the red circle in the top left corner, or use Command+Q to close the active process.
- On iPhone and Android, swipe up from the bottom or use the recent apps menu to close applications running in the background.
- Closing unneeded applications can improve your device's speed and battery life.
Closing applications on Windows
The simplest way to close an process on Windows is to look for the X button in the top right corner of the window. Click that X and the program shuts down when ready. This works for nearly every Windows program — web browsers, word processors, email clients, and games all close the same way.
If a window is frozen or not responding, the X button may not work. In that case, use the keyboard shortcut Alt+F4 while the frozen window is active. This forces Windows to close the program. If that does not work either, you can open the Task Manager by pressing Ctrl+Shift+Esc, find the frozen program in the list, click it, and then click the "End Task" button at the bottom right.
When you close a program, Windows may ask if you want to save your work. If you have unsaved documents open, click "Save" before closing. If you click "Don't Save," any changes you made since you last saved will be lost.
Closing applications on Mac
On a Mac, look for the red circle button in the top left corner of the window. Click that button to close the process. You can also use the keyboard shortcut Command+Q, which closes whichever program is currently active (the one you are using right now).
Command+Q is faster once you get used to it, especially if you have many windows open. Command+W closes only the current window but leaves the process running — useful if a program has multiple windows open and you want to keep the others going.
Like Windows, Mac will ask you to save unsaved work before closing. If you see a dialog asking whether to save, click "Save" to keep your changes or "Don't Save" to discard them.
Closing applications on iPhone and iPad
On newer iPhones and iPads (those with Face ID), swipe up from the bottom of the screen and pause briefly. This shows all your open applications as cards. Find the app you want to close, swipe it upward, and it closes. On older iPhones with a home button, double-click the home button instead to see open apps, then swipe the app upward to close it.
Most people do not need to manually close apps on iPhone or iPad. Apple's system automatically manages background apps and closes them when your device needs memory. Closing apps manually only helps if an app is frozen or behaving strangely.
Closing applications on Android
Android phones vary by manufacturer, but most work similarly. Swipe up from the bottom of the screen (or tap the recent apps button, usually on the bottom right) to see all open applications. Swipe each app upward to close it, or tap "Close All" if your phone offers that option.
Like iPhone, Android automatically manages background apps. You do not need to close every app you use. Close an app only if it is frozen, using too much battery, or behaving incorrectly.
When closing an process does not work
Sometimes an process will not close normally. This usually means the program has stopped responding. On Windows, use Alt+F4 or Task Manager as described above. On Mac, use Command+Option+Esc to open the Force Quit menu, select the frozen app, and click "Force Quit."
On iPhone, if an app is frozen, close it using the swipe method described above and then reopen it. On Android, go to Settings, tap Apps, find the frozen process, and tap "Force Stop."
If an process keeps freezing, try restarting your device. Restart clears your device's memory and often fixes problems that cause apps to freeze. After restarting, open the app again to see if it works normally.
The difference between closing and uninstalling
Closing an process stops it from running right now, but the program stays on your device. You can open it again whenever you want. Uninstalling removes the program from your device entirely. You would need to read and install it again if you wanted to use it later.
Close an app when you are done using it for now. Uninstall an app when you no longer want it on your device and want to free up storage space. Most people close apps far more often than they uninstall them.
Frequently Asked Questions
Does closing an app delete my files or data?
No. Closing an process does not delete anything. Your files, photos, documents, and any data the app created stay on your device. When you reopen the app, your data is still there.
Will closing apps make my device faster?
Closing apps you are not using can free up memory and improve battery life, especially on phones. However, modern devices manage background apps automatically, so closing apps is not usually necessary unless one is frozen or draining battery noticeably.
What happens if I close an app without saving my work?
Most applications warn you before closing if you have unsaved changes. If you click "Don't Save," any changes since your last save are lost. Always save your work before closing if you want to keep it.
Can I close multiple apps at once?
On Windows and Mac, you close one window at a time. On iPhone and iPad, you can swipe multiple app cards upward in succession. On Android, many phones have a "Close All" button in the recent apps menu.
Is it bad to leave apps running in the background?
Leaving many apps running in the background drains battery and uses memory, which can slow your device. However, your device's system automatically manages background apps and closes them when needed. Close apps manually only if you notice battery drain or slowness.
