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

• Open Settings.
• Tap Mobile Data (or Cellular).
• Tap Mobile Data Options.
• Turn on Low Data Mode.
• Low Data Mode helps reduce background network activity, such as automatic updates and app refresh.

Manage Background App Refresh

• Go to Settings → General → Background App Refresh.
• Select Wi-Fi or Off to stop apps from using mobile data when they’re not active.

Restrict Data for Specific Apps

• Go to Settings → Mobile Data (or Cellular).
• Scroll down to see which apps are using mobile data.
• 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.
• Open Settings → Mobile Data (or Cellular).
• Scroll to the bottom and turn off Wi-Fi Assist.

Update Apps Using Wi-Fi Only

• Go to Settings → App Store.
• 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.
