Restrict background data in specific Android apps
There are many Android apps that, without your knowledge, will go ahead and connect to your cellular network even when the app is closed. This “background data” can be used even when your device is in standby mode (with the screen turned off), as these apps are constantly checking their servers through the Internet for all sorts of updates and notifications.
While you can easily restrict background data usage across all your apps using the Data Saver feature built into the Settings menu, it’s also very simple to restrict background mobile data for individual apps on your Android phone.
The Data usage section in Android Settings lets you view the amount of data used by each specific app. If you notice an app using more background mobile data than you’d like it to (Snapchat comes to mind), you can restrict it from accessing the Internet till you’re back in a Wi-Fi covered area. If you’re looking to conserve your bandwidth and lower that monthly phone bill, this feature is definitely worth checking out.
