Step by step

1. 

   Open Lock screen

   Open Settings and tap Lock screen, below More connectivity options.

   Done

2. 

   Tap Sleep

   Sleep is the first row, under Lock screen settings. Ours said After 10 minutes of inactivity.

   Done

3. 

   Pick a time

   A sheet called Lock screen automatically opens with 15 seconds, 30 seconds, 1 minute, 2 minutes, 5 minutes and 10 minutes. Tap the one you want. Ours had 10 minutes ticked, with no longer option and no Never.

   Done

4. 

   Read the note

   The sheet warns: Displaying static content for extended periods of time may make colours uneven. We tapped Cancel.

   Done

If you do not see this option

• Looking under Display? Our Display & brightness page had no timeout row. At the bottom, Need other settings? links to Lock screen.

  

• No Lock screen row? Xiaomi says that on some phones the route is Settings, Always-on display & Lock screen, Sleep. Source: How to set screen sleep time?
• Want Never? Not on our phone. Xiaomi says the REDMI Pad SE 8.7 tablet offers 1, 2, 5 or 10 minutes or Never under Lock screen, Sleep. Source: How to set the sleep time on the REDMI Pad SE 8.7?

If this does not work

• Screen turns off while you watch a video? Xiaomi suggests picking 10 minutes under Sleep, turning off Battery saver, and checking the video app's own Sleep timer. Source: What to do if the REDMI Pad SE screen automatically turns off while playing videos?
• Battery drains faster? A long Sleep time keeps the screen on longer. Check what uses power: battery mode and battery use.

About this guide

Xiaomi calls the screen timeout Sleep, and it sits under Lock screen, not under Display.

The screenshots are from our Redmi Note 15 Pro 5G with Xiaomi HyperOS 3.0.308.0 and Android 16, in Light mode. Ours was set to 10 minutes. We opened the list and tapped Cancel.

Good to know

Raise to wake, just below Sleep, wakes the screen when you lift the phone. It was off on ours.

In short: Settings, Lock screen, Sleep, pick 15 seconds to 10 minutes.
