It’s possible to force some Android apps to only use Wi-Fi while other apps use the mobile data connection. You might want to do this if you have an app that uses a lot of data, but isn’t required to run all the time or be constantly available. An example of this is updating apps; You don’t need to install app updates as soon as they come out, it’s fine to leave it until you get home and can update your apps over the Wi-Fi connection. Here’s how to make an Android app only use Wi-Fi (In this example, I will show how to set Android to only update apps over Wi-Fi):
- Click on Settings
- Click on Data Usage
- Select the app you want to only use Wi-Fi (to stop apps updating over 3G / 4G and only use Wi-Fi, select the Google Play app)
- Scroll down and click on Restrict background data -> OK
This will stop the app from using 3G / 4G and only access the internet over the Wi-Fi connection.
