Step by step

1. 

   Open Power button

   Search Settings for Power button. System & update also suggests it at the bottom, under You might be looking for.

   Done

2. 

   Check the settings

   Ours had Double click the Power button: None, and Press and hold the Power button: Digital assistant. Tap Press and hold the Power button.

   Done

3. 

   Choose Power menu

   Choose Power menu instead of Digital assistant (Google). OnePlus's manual says that holding the Power button then opens the Power menu, with Power off and Restart.

   Done

About this guide

If holding the Power button starts the assistant instead of offering Power off, this setting is why.

The screenshots are from our OnePlus Nord 5 with OxygenOS 16.0.5.1201 and Android 16, in Dark mode. We only looked at these settings and changed nothing.

Good to know

Take a screenshot with the buttons: screenshots and screen recording.

In short: Settings, search Power button, Press and hold the Power button, Power menu.
