Which Apps Are Using The Most Data?

Below Current Period, you’ll see which of your apps are using the most data. If you don’t want an app to be able to use data, turn off the switch to the right of the app.

You can also tap on System Services to see which services are using the most data. This amount of data is almost always a negligible amount.

Want To Reset The Current Period?

If you want to reset the Current Period so you can keep track of the data you’ve used in a certain window of time, you can do so by tapping Reset Statistics. This feature is great for keeping track of how much data you use in a single month, especially if you don’t have an unlimited data plan.

To Reset Statistics, go to Settings -> Cellular -> Reset Statistics. Then, tap Reset Statistics when the confirmation alert appears at the bottom of the screen. Once you do, you’ll see that it says “0 bytes” next to Current Period.
