How to turn off screen attenuation on Xiaomi devices: all ways

Your Xiaomi screen goes out too quickly, making it difficult to read articles, watch videos or use the device as an alarm clock? This problem is familiar to many owners of smartphones, tablets and TVs of the brand. Automatic attenuation of the display is a standard feature of energy saving, but sometimes it becomes a real obstacle. Fortunately, MIUI and Android TV from Xiaomi has several ways to turn off this timer or increase its duration.

In this article, we will go through all possible methods, from basic settings on the menu to hidden settings for power users. You will learn how to change the fade time on Redmi, POCO and Mi smartphones, as well as on Mi TVs. We will focus on the nuances for different versions of MIUI (including MIUI 14 and HyperOS) and solving problems if the standard settings do not work. If you are looking for a way to keep the screen on all the time - for example, for a navigator, presentation or monitoring - here you will find work instructions.

Why Xiaomi’s screen is going out: the reasons and mechanisms

Before you turn off the attenuation, it is important to understand why it is necessary. In Xiaomi devices, automatic disabling of the display is controlled by several systems:

• 🔋 Energy saving: the main reason is battery saving. AMOLED-screens (for example, Xiaomi 13 or Redmi) K60) This is especially important because each pixel consumes energy.
• ⚙️ Android Settings: Based on the standard Screen Timeout mechanism, which limits inactivity time.
• 🛡️ Safety: on certain models (e.g, POCO F5) The screen is locked after 30 seconds without activity to prevent unauthorized access.
• 📺 Features MIUI: branded shell adds its algorithms, for example, adaptive attenuation depending on lighting (Adaptive Brightness function).

On Mi TVs. TV redmi TV screen attenuation is often associated with Sleep Timer, which is activated when there is no signal from the remote or HDMI-Unlike smartphones, the timer here can be triggered in 10 to 30 minutes, not seconds.

Interestingly, on some models (such as the Xiaomi Pad 6), the fade time depends on the current power consumption profile: in Performance mode, the screen can stay on longer than in Battery mode.

Method 1: Standard MIUI settings (for smartphones and tablets)

The easiest method is to change the fade timer through the settings menu, which is suitable for all devices on MIUI 12-14 and HyperOS, including Redmi Note 12, POCO X5, Xiaomi 12T and others.

Steps:

1. Open the Settings app (cog icon).
2. Go to the Display section.
3. Find Sleep Mode or Screen Timeout.
4. Choose the maximum value from the suggested value (usually up to 10 minutes or 30 minutes).
5. To disable the attenuation, select Never, if this option is available.

On some firmware (e.g. MIUI 13 for Redmi 10), the item may be called Automatic Screen Shutdown. If you don't find this section, try searching by settings (the magnifying glass icon at the top).

Check out the MIUI version in the About Phone section.

Connect the device to charge (recommended for long-term tests)

On Mi TVs (e.g. Mi TV Q2), the developer mode is activated similarly, but the path may be different: Settings → About TV → Firmware version (press 7 times). After that, the Developer option will appear on the menu where you can turn off sleep mode.

Important: On HyperOS devices (such as Xiaomi 14), the path to the developer settings may change.

Method 3: Using applications to control the screen

Method 4: Disable attenuation on Mi TV and Redmi TV

On Xiaomi TVs, the screen fade algorithm is different from smartphones, where the screen can go out due to:

• 📶 Lack of signal from the remote (timer of inactivity).
• 🔌 Energy-saving mode (Eco Mode).
• ⏱️ Sleep Timer (Sleep Timer).
• 🎮 Lack of activity on the HDMI (If you have a PC or console connected).

Instructions for Mi TV 4S/5X/6 and Redmi TV A2/A3:

2. Go to Settings → System → Sleep Timer.
3. Turn off the option or set the value off.
4. To disable attenuation when the remote is inactive: Go to Settings → Display and Sound → Energy Saving. Turn off Auto-Switching.

If the screen goes out when you connect to a PC or game console:

1. Go to Settings → HDMI → HDMI mode.
2. Select Game Mode or PC Mode.
3. Turn off the HDMI Energy Saving option.

💡

On Xiaomi TVs with Google TV (e.g. Mi TV Q2 2023), screen fading can be turned off via Android TV settings: Settings → Display and Sound → Sleep Mode → Never.

Method 5: ADB commands for power users

If standard methods don’t work, you can use Android Debug Bridge (ADB), which is suitable for all Xiaomi devices, but requires a computer and basic command line skills.

Step-by-step:

1. Enable USB debugging in the developer settings (see Method 2).
2. Connect the device to the PC and install ADB drivers.
3. Open the command prompt (Windows) or terminal (macOS/Linux) and type: adb devices Make sure your device appears in the list.
4. To disable attenuation when connected to charging: adb shell settings put global stay_on_while_plugged_in 3
5. To set the attenuation timer on 1 hour (3600 second): adb shell settings put system screen_off_timeout 3600000

To return the standard settings, use:

adb shell settings put system screen_off_timeout 30000

(where 30,000 to 30 seconds).

⚠️ Attention: Misuse of the right ADB Do not change other settings unless you are sure of their purpose. For example, an adb shell settings put global with incorrect values can disrupt sensors or wireless modules.

💡

ADB commands are valid until the next device restarts, so that the changes are permanent, you need to write them in the initialization script or use applications like Tasker to automatically execute after booting.

Problem Solving: What to do if the screen goes out anyway

Sometimes even after changing all the settings, the Xiaomi screen continues to fade. Let’s consider the typical causes and ways to eliminate them:

• 🔄 Application conflict: Some programs (such as Greenify or Battery Saver) force the screen to turn off. → Annexes → Auto-start.
• 🔋 Aggressive Battery Mode: In Settings → Battery → Battery mode select Performance instead of Saving Charge.
• 🛠️ Firmware failure: After update MIUI You can reset your screen settings to the standard settings. → System system → Resetting settings → Resetting display settings.
• 📱 Proximity sensor problems: On some models (e.g. Redmi 9), the screen goes out due to false alarm. Check it in test mode: dial ##6484## in the dialer.

If the problem persists, try calibrating the battery:

1. Charge the device to 100%.
2. Turn off charging and use the phone until it is fully discharged (before it is turned off).
3. Charge again to 100% without interruption.

On Mi TVs, the reason may be a firmware update. If the screen has gone out more often after the update, try rolling back to the previous version via Settings → About TV → System Update → Recoil.
