When you exit an app on your smartphone to return to your home screen or move on to another task, that app doesn’t actually close. Instead, it continues to run in the background just in case you need to bring it up again quickly.
Apps running in the background are similar to a window being minimized on your computer. When you minimize a window on a computer, you’re not fully closing it; the only way you can fully close a window is to press the X in the top right corner.
Fully closing apps on your phone will make it run faster, and drain your battery more slowly. So, what’s the best way to do this? The answer depends on which type of operating system you’re using—Android, or iOS (iPhone). Here are the steps you need to follow to close out apps on each.
Android Smartphone: The easiest way to close apps on an Android device is to start by swiping up from the bottom of your phone screen. This will reveal all of the apps that are currently still operating—and often, you’ll be surprised by how many there are!
Each phone will have a slightly different method for closing apps from here. Some may show slightly different wording or symbols, like Close All, or an X. Other devices sometimes require you to swipe all the way to the end of your open apps before you’ll see any type of Close all button.
Regardless, simply work through the open apps and close any that you don’t plan on using anytime soon. And remember that closing an app doesn’t permanently remove it from your device (that’s an entirely different process). It simply closes down the app until the next time you need to use it.
iOS (iPhone): For iPhone users, the need to close apps isn’t quite as urgent. The iOS operating system is designed to “intelligently” manage apps, putting them into a suspended, low-power and low-memory state when you’re not using them.
That said, there may be times when you really want to close an app, like for instance if it’s not responding. In that case, how you close them depends on the model of iPhone. On models iPhone X or later, which don’t have a “home” button, swipe up from the bottom of your screen to see all the apps you currently have open. Then, swipe side-to-side through the apps, and swipe up on any app you want to close.
For earlier (iPhone 8 and older) models, double press the Home button, then swipe through the apps as described above to close them. Having too many apps open won’t damage your phone in any way, but it will definitely result in slower performance, and you’ll probably notice your battery draining faster. Try to get in the habit of closing your apps right after you use them, or to close your apps at the end of the day before you go to sleep. Your phone will thank you!
