Android apps are fun to use and are useful too, but they can also be the culprit behind extreme data usage in your mobile phone. But the good news is that you can control the amount of data your apps consuming in your Android device. In order to control it, you need to first understand that how an installed app consumes data. For Android users, it’s very simple to find out. Go to Settings > Data usage and here you can check how much data each app is using. Just scroll down through the list and all the information is available at your fingertips. This list is sorted in descending order as per consumption data and that is why most data consuming app is on the top of the list.
You can also select an individual app from the list and go into more detail that how exactly data is being used. You can find out how much of the data was used visibly or directly and how much was used in the background.
You can restrict background data use for each app on a case by case basis, but before that just make sure that Restrict background data is turned on. Tap View App Settings and you can also ensure that any auto-updates to that app occur only over Wi-Fi.
You can also keep a watch on data usage on monthly basis by selecting the date range according to your billing cycle and manage your usage of data usage accordingly in order to avoid overshooting your monthly bill. You can set a data limit (both MB and GB units are available for your convenience) and your phone will automatically restrict data when exceeding the limit. You also have the option to check compare data usage of the previous month and see that how your data usage, whether overall or for each app, has changed over the months.
