Step by step

1. 

   Open Data usage

   In Settings, Apps, open the app's App info and tap Data usage.

   Done

2. 

   See how much it used

   Chrome used 48,1 MB on ours: 30,0 MB foreground, 18,1 MB background.

   Done

3. 

   Block Wi-Fi

   Switch Disable Wi-Fi on. There was no confirm box.

   Done

4. 

   Check the app

   Chrome showed No internet, and a box: Wi-Fi disabled for "Chrome", with Later and Enable. Disable mobile data works the same way.

   Done

5. 

   Stop background data

   Switch Background data off. The app still works when open. We switched both back.

   Done

6. 

   Or set every app at once

   Settings, Mobile network, Data usage, Network access lists each app with its Wi-Fi & mobile data setting.

   Done

If you do not see this option

• OxygenOS 14 (OnePlus manual)? The manual's route is Settings, Mobile network, Data usage, Network access, then the app. That route still works on ours. Source: OxygenOS 14.0 User Manual
• Unrestricted data? There is no row on the app's page. Unrestricted apps is in Mobile network, Data usage, Data saving, and is greyed out while Data saving is off.

If this does not work

• App says no internet? Disable Wi-Fi or Disable mobile data is on. Tap Enable in the box, or switch it off.
• Messages arrive late? Background data is off. Switch it on. Source: Reduce and manage mobile data usage

About this guide

You can block one app from the internet without turning data off for the whole phone.

The screenshots are from our OnePlus Nord 5 with OxygenOS 16.0.5.1201 and Android 16, in Dark mode. We opened Chrome's page; nothing was changed. Some screenshots were retaken after the 18 October 2026 patch (version CPH2709_16.0.5.1201(EX01C10P02)).
