The manufacturer hid the settings of the screen shutdown timer so deeply that even experienced users spend 15 minutes searching. MIUI This function is not present in its usual form.

In this article, 3 proven ways to set up automatic screen shutdown on any Xiaomi, Redmi or smartphone POCO (And we'll look at the models from 2020 to 2026:

• 🔍 Where to look for a timer in standard settings (and why it may not be there)

Important: Instructions are relevant to MIUI 12-14 and Android 11-14. If you have an older firmware version, some menu items may be different, we will warn you about this separately.

Method 1: Standard sleep timer in screen settings

The most obvious way is through the Settings menu. → But here's the first catch: on different Xiaomi models, this option may be called differently or not at all. Here's how to find it on most devices:

1. Open the settings (cog icon on the desktop).
2. Go to the Screen section.
3. Scroll down to the Sleep Mode or Sleep Timer block (on some firmware – Auto Shutdown).
4. Choose the appropriate interval: from 15 seconds to 30 minutes.

Method 2: Developer settings – flexible timer setting

If the standard settings are not satisfactory (for example, you need to set a timer for 5 minutes, and the maximum value is 2 minutes), the Developer Settings menu will help. This method works on all Xiaomi devices, but requires pre-activation of hidden mode.

How to turn on the developer parameters:

1. Open the Settings. → The phone.
2. Find the MIUI version string and tap it 7 times in a row.

Now set the timer:

1. Go to the Developer Settings.
2. Find the Sleep item when inactivity (or screen timeout).
3. Select the desired value from the list (options are available up to 10 minutes).

⚠️ Attention: Changing the developer settings may affect the stability of the system. We do not recommend changing other settings in this menu unless you understand their purpose. For example, disabling animations or background processes can lead to a freeze in the interface.

On devices with a Snapdragon 8 Gen 2 processor (for example, Xiaomi 13 Ultra), an advanced “Adaptive Sleep Timer” mode is available in the developer parameters, which automatically adjusts the screen turn off time depending on the applications running.

Method 3: Timer apps – when regular funds don’t work

How to install and configure:
