How to Check Data Usage on Android

Open your Android's Settings. It's the Android 7 Settings icon typically found on the home screen or in the app drawer.

Tap Data usage. You should now see the total amount of mobile data used in the current month at the top of the screen.

Select a date range. Skip this step if you only want to see the current month's usage. Tap the drop-down menu that contains the current month's dates, then select the date for which you want to view usage data.

Tap App usage. It's a blue link near the bottom of the page. The total data used appears at the top of the screen, and you'll also see how much data was used by each app. Apps that used the most data appear at the top of the page.
