How to Check iPhone App Data Usage in iOS 9


Cellular data usage by the apps on your iPhone is an important thing to consider for almost everyone that has a cellular plan with a fixed amount of data. We have previously shown you how to turn off cellular data for a single app on your iPhone, but determining which apps to restrict to Wi-Fi might be difficult.

One way to make this decision easier is to learn which apps are using the most data. Fortunately your iPhone has a menu that shows data usage for each app. Our guide below will show you where this menu is located so that you can determine how your cellular data is being consumed.

Note that the data you will find using the steps below is only for the device on which you are checking it. If, for example, you are on a family plan with your cellular provider and you share data with other people, then you will need to perform these steps on their devices as well. Additionally, if this is the first time that you have been on this menu, then the data usage amounts shown are probably for a long period of time. You may need to reset your statistics and wait a few days to get a better understanding of your current data usage.

 

Here is how to check which iPhone apps are using the most data in iOS 9 –

  1. Open the Settings menu.
  2. Select the Cellular option.
  3. Scroll down and locate an app. The number shown below the app indicates the amount of data that the app has used since the statistics were last reset.

These steps are repeated below with pictures –
