If you do not see this option

• Mobile data instead? The OnePlus manual puts it under Settings, Mobile network, Data usage, with Data usage by app and a daily or monthly limit. Ours has no SIM, so we could not check it. Source: OxygenOS 14.0 User Manual
• On OxygenOS 14? The manual calls the switches Disable mobile network and Allow in the background. Ours says Disable mobile data and Background data. Source: OxygenOS 14.0 User Manual

If this does not work

• An app uses too much? Turn off Background data for it. Source: Reduce and manage mobile data usage
• Keep an app off Wi-Fi? Tap it in Data usage by app and switch on Disable Wi-Fi.

About this guide

Data usage shows which apps download the most.

The screenshots are from our OnePlus Nord 5 with OxygenOS 16.0.5.1201 and Android 16, in Dark mode. It has no SIM, so only Wi-Fi data shows.

Good to know

Use the Privacy dashboard on a OnePlus.

In short: Settings, Wi-Fi, three dots, Wi-Fi data usage, Data usage by app.
