How to check which apps are using data on your iPhone

Have you noticed you’ve been running low on data each month but you’re not sure why? Or perhaps you just want to know which apps use the most internet? Whatever the reason, it’s good to know which apps are using the most data on your iPhone.

Checking each app’s data usage is incredibly quick and easy. We’ve put together a step by step guide so you can check your iPhone’s data usage yourself. 

What you’ll need:

  • An iPhone that has a mobile connection

The short version:

  1. Open Settings
  2. Tap Mobile Service
  3. Scroll down to Mobile Data
  4. Adjust app’s data usage
  1. Step

    Open Settings

    Enter the Settings app on your iPhone.

  4. Step

    Adjust app’s individual data usage by turning its toggle on or off

    If you’ve noticed a particular app is using more data than necessary, simply tap the toggle to turn it off. This means it won’t use mobile data to load and instead just use Wi-Fi when it’s connected.iPhone Mobile Service page with Spotify and Chrome apps and their data usage highlighted


I rarely use a certain app but it uses lots of data. Why is this?

Lots of apps are set to automatically update or to run in the background, even if it’s not open. 

How can I limit how much data all of my apps use in the background?

If you’ve tried to limit a few apps’ data usage but find overall you’re still using a lot then try putting your iPhone in Low Data Mode. To do this, repeat steps one and two above and then select Mobile Data Options. Select Data Mode, then choose Low Data Mode, as shown here.

Selecting Low Data Mode helps reduce mobile data usage by pausing automatic updates and background tasks.
