How can I save data usage on my iOS device?

If you’re using a limited data plan or travelling, you can reduce how much mobile data your iPhone uses by adjusting a few settings.

Turn on Low Data Mode

1. Open Settings.

2. Tap Mobile Data (or Cellular).

3. Tap Mobile Data Options.

4. Turn on Low Data Mode.

Low Data Mode helps reduce background network activity, such as automatic updates and app refresh.

Manage Background App Refresh

1. Go to Settings → General → Background App Refresh.

2. Select Wi-Fi or Off to stop apps from using mobile data when they’re not active.

Restrict Data for Specific Apps

1. Go to Settings → Mobile Data (or Cellular).

2. Scroll down to see which apps are using mobile data.

3. Turn off the toggle for any app you don’t want using mobile data.

Turn Off Wi-Fi Assist

Wi-Fi Assist automatically switches to mobile data when your Wi-Fi signal is weak.

1. Open Settings → Mobile Data (or Cellular).

2. Scroll to the bottom and turn off Wi-Fi Assist.

Update Apps Using Wi-Fi Only

1. Go to Settings → App Store.

2. Under Mobile Data, turn off Automatic Downloads or select Wi-Fi only.

Notes

• You can turn on Low Data Mode for both mobile data and Wi-Fi separately.

• Limiting background data helps you stay within your plan allowance and can also improve battery life.
