Android device used: Google Nexus 4
Android version: Android 4.2
You can restrict background data on android 4.2 but it is a bit different from previous versions.
In Android 4.2 the setting is a bit hidden so you must know where to search for it.
You can restrict background data by going to the data usage.
1. Go to Settings
2. Select Data Usage
3. Press the 3 dots right up
4. Check Restrict background data
Now you see a notification on the notification bar, your background data is only updated when connected to a Wi-Fi.
If you press the notification bar, then the settings is removed.
