Some apps run in the background and use the WiFi or mobile data service. If you don’t use the app often, you should either remove it or change the settings of your phone to make sure that the inactive app doesn’t consume data.
Not all apps are junk. Some applications are important and you must not mess with their settings. For example, the OS updater application makes sure that your phone software is up to date. If you disable it, your phone might be vulnerable to security threats.
To identify apps that are using WiFi or mobile data connection, you must use a data monitoring app.
