1. Go to Settings > Data usage.

2. Touch Billing cycle.
3. To set a warning, turn Set data warning on , then touch Data warning and enter the amount of data.

About background data

Even when you’re not actively using them, most apps use data in the background to sync information and deliver notifications.

To conserve data when you’re running low, you can use Data Saver to turn off background data for all apps. Or, to restrict background data used by an app indefinitely, you can turn off background data specifically for that app.

Notifications only when you open the app

When you turn off background data for an app, it won't sync until you open it, so you will receive NO notifications until you open the app and it syncs.

Restrict for all apps when you’re low

1. Go to Settings > Data usage.

2. Touch Data Saver and turn it on .

   You'll see in your status bar and all apps are prevented from using background data.

3. To allow certain apps to continue using background data, touch Unrestricted data access, then next to the app name, slide the switch on .

Restrict for specific apps indefinitely

1. Go to Settings > Data usage.

2. Touch Cellular data usage.
3. Touch an app, then turn Background data off .

The Data Saver tile in quick settings lets you easily toggle Data Saver on or off. To replace an existing quick settings tile:

1. Drag down the status bar with two fingers to open quick settings, and touch .
2. Drag the Data Saver tile to the desired position in quick settings.

If you have to pay for data usage on a Wi-Fi network, you can restrict apps from using background data on that network.

1. Go to Settings > Data usage.

2. Touch Network restrictions.

3. For each Wi-Fi network where you pay for data usage, slide the switch on to indicate it is a metered Wi-Fi network.

   Any restrictions that you set up on background data for cellular networks will also apply for these metered Wi-Fi networks.
