How many apps do you have running in memory on your Android device? There's no shame in admitting you have several apps running in the background. Currently, I only have three apps running, including the Settings app I opened in preparation for this article.
I'm one of those who regularly -- and manually -- close apps on my phone.
Why?
Resources.
Although Android has become quite good at managing system resources, the more apps you have running in the background, the fewer resources will be available to use.

Then there's the potential security and privacy risk: An app running in the background can continue using things like your phone's camera or mic, at this could enable a rogue app to take over the camera or mic. Do understand that simply leaving an app running in the background isn't a surefire route to this problem -- but it certainly doesn't help.
Yes, Android also has become very good at letting us know when an app is using either the camera or the mic but it's always better safe than sorry -- especially when it comes to our phones.
Here's the problem: When you have an app running, and you swipe up to open the App Drawer and then open yet another app, what happens with the app you were previously using?
It runs in the background.
Although there's no "Close" button for Android apps, there are different ways you can close an app and prevent it from consuming precious resources on your device.
Let me show you the three ways of doing this.
Closing an app from the overview
What you'll need: The only thing you'll need is a phone running Android. Since the third of these methods is found only in the latest version of the OS, you'll need Android 15 installed to use it. The other two methods should be universal across all recent versions of the platform.

You might be surprised at how many apps are still running on your device.
Closing an app from Settings
Apps should be listed under "Connected devices."
Since I'm not using the Amazon app, it can go bye-bye.

Closing the app from the notification shade
This feature is unique to Android 15, so if your phone is running an older version, it won't be available for you. This method is more about closing apps that are running as background services and not so much for general apps you use. For example, I use AirDroid to simplify sharing files between Android and MacOS. Even when I'm not using the AirDroid app, it continues running in the background to listen for requests from MacOS. That's the nature of a background service.
The active app pill first appeared in Android 15.

Which method should you use? It depends. If you want to stop background services, the last method is the easiest (but requires Android 15). If you're looking for the fastest method, the app overview is, hands down, the best. If you have problems getting the app overview to appear, going through the Settings app is your best bet.
And that, my friends, is how you can close a running app on Android to free up system resources and ensure an app doesn't continue using features (such as the camera or mic) when it shouldn't.
