How to completely disable sleep mode on Xiaomi devices: TVs, smartphones, tablets

Sleeping (or sleep) on Xiaomi devices is a power-saving feature that automatically shuts down the screen or puts the gadget in a low-consumption state after inactivity. On Mi TVs, this manifests as a screen dimming or going into standby mode, and on smartphones, as a lockdown of the display at a given interval. While it is useful for saving battery or power, it interferes with many users, such as watching long videos, reading recipes in the kitchen or using the device as a digital frame.

In this article, we will discuss all possible ways to turn off sleep mode on different Xiaomi devices, from Mi TV A2/A Pro/ES/P1 to smartphones on MIUI 14/15 and Pad 6/Pro tablets. Special attention will be paid to hidden settings that are not obvious in the standard menu, and also consider the problems that arise after firmware updates. If you are faced with the fact that the screen goes off too quickly or the device goes to sleep contrary to your settings, here you will find a solution.

Why sleep mode may not be turned off in standard ways

Before we get to the instructions, it is important to understand why sleep settings are sometimes ignored by the system.

• 🔄 Application conflict: Some programs (e.g. Google Play Services or Mi Fit) force the power saving to be activated.
• 📱 Limitations MIUI: Xiaomi smartphones run background optimizations that can reset sleep timers.
• 📺 Corporate functions of TVs: in Mi TV There is a separate mode of "Eco-sleep", which is activated at low activity.
• 🔧 Failures after updates: firmware MIUI 14+ Google TV 12+ Sometimes they reset user settings.

For example, after upgrading to MIUI 15, many Redmi Note 12 and POCO X5 users complained that the screen locks after 30 seconds, despite the set value "Never" This is due to the activation of the Adaptive Battery feature, which automatically adjusts sleep timers. And on Xiaomi TV Q2, sleep mode can be turned on due to the light sensor, if the room is too dark.

Disable sleep mode on Xiaomi TVs (Mi TV, Redmi Smart TV)

On Xiaomi TVs, sleep mode is regulated via the power saving menu and sleep timers. The interface may vary depending on the model and firmware version (PatchWall or Google TV). Below is a universal instruction for most devices, including the Mi TV A2 43, Redmi Smart TV X50 and Xiaomi TV Q2 55.

Step 1. Open Settings → Device and General settings → Energy saving.

Step 2. Find Sleep Mode (or Sleep Timer) and select Disable.

Step 3. If you don’t have an option, go to Settings → System → Advanced Settings → Standby mode and set Never.

Turn off the light sensor (if any)

Disable the mode "Eco-sleep" in energy saving

Make sure there are no active timers in the Clock app

Restart the TV after changes-->

On Google TVs (e.g. Xiaomi TV A Pro 2023), the path is different:

1. Press the Settings button on the remote → select All settings.
2. Go to the System → Energy Saving → Sleeping mode.
3. Set the switch off or schedule (if you only need to turn off at night).

Important: On Xiaomi TVs with a presence sensor (Models 2022+), sleep mode can be activated if the system does not detect movement in the room. To turn off this feature, go to Settings → Smart Home → Presence Sensor and deactivate the Automatic Sleep option.

Setting up a sleep timer on Xiaomi smartphones (MIUI 12-15)

On Xiaomi, Redmi and POCO smartphones, sleep mode is regulated through screen and battery settings. However, due to the features of MIUI, the standard lock timer shutdown doesn't always work. Let's look at all the ways.

Method 1: Standard screen settings

1. Open the Settings → Display.
2. Select Sleep Mode (or Screen Timeout).
3. Set the maximum value (usually 10 minutes or 30 minutes).
4. On some models (for example, Xiaomi 13 Ultra) the item Never is available.

Method 2: Disconnecting the adaptive battery

Adaptive Battery in MIUI can reset sleep timers to turn it off:

1. Go to Settings → Battery and Performance → Battery Settings
2. Disable the Adaptive Battery and Optimize Power Consumption.
3. In the Applications section, find system services (such as Android System) and remove restrictions from them.

Critical feature: On smartphones with MIUI 14+, when activated, the Ultra Battery Saver mode resets the sleep timer up to 30 seconds regardless of your settings. To avoid this, turn off this mode in Settings → Battery → Power Saving Modes.

Alternative methods of shutting down sleep (for experienced users)

If standard methods don't work, you can use hidden settings or third-party tools, which are suitable for advanced users, because they require access to system settings.

Method 1: ADB-teams (for smartphones)

With Android Debug Bridge, you can force a sleep timer to any value, including "Never."

1. Turn on USB Debugging in Settings → About Phone → MIUI version (click 7 times on the line with the version).
2. Connect your smartphone to your PC and execute the command: adb shell settings put global stay_on_while_plugged_in 3 (where 3 — The mode is always on when charging and from the battery").
3. Please use the following: adb shell settings put global stay_on_while_plugged_in 0

Method 2: Editing system files (routed devices only)

On root-access devices, you can manually change the sleep settings in the /system/build.prop file. Add or change the lines:

ro.config.screen_off_timeout=0


ro.config.sleep_mode=false

After saving, restart the device.Caution: improper editing of system files may result in loss of warranty or device "brick".

💡

If you use your smartphone frequently for navigation or reading, install the Keep Screen On app from Google Play, which allows you to temporarily turn off sleep mode for specific applications without changing your system settings.

Method 3: Using Tasker or Automate

Automation via Tasker or Automate allows you to flexibly control sleep mode, for example, you can create a rule:

• 📱 If the YouTube app is running → switch off the sleep timer.
• 🔋 If the charge level is below 20% → return the standard settings.
• 🕒 At night (23:00-7:00) → allow sleep in 5 minutes.

Frequent problems and their solutions

Even after you turn off sleep, Xiaomi users face unexpected problems, and let's look at the most common cases and how to fix them.

⚠️ Note: If you have updated the firmware on the TV Mi TV Sleep settings are gone, try resetting the system cache through Settings → Warehouse → Clear the cache. This often helps to return hidden menu items.

Problem 1: The screen goes out after 10 seconds, despite the settings

Reason: Slides Show or Eco-mode is activated.

Decision:

• 🖼️ Open the Settings. → Display. → Show slides and disable the function.
• 🌿 On TVs, check Settings. → Energy conservation → Eco-regime.

Problem 2: Sleep is turned on on on a smartphone when connected to Bluetooth devices

Reason: Smart lock function in MIUI conflicts with some headsets.

Solution: Go to Settings → Connected Devices → Bluetooth → Cog settings → Smart lock and disable the option.

Problem 3: TV goes to sleep when watching through HDMI

Reason: HDMI-CEC mode is activated, which synchronizes the state of devices.

Solution: Turn off HDMI-CEC in Settings → Devices → HDMI-CEC or update the TV firmware.

💡

If none of the methods worked, check the physical power button on the TV - sometimes it sticks and forcibly puts the device into sleep mode.

How to Recover Standard Sleep Settings

If after experimenting with settings you want to return everything as it was, do the following:

For Xiaomi TVs:

1. Go to Settings → System → Reset.
2. Select Reset Image and Sound Settings (does not affect personal data).
3. Or perform a full reset to factory settings (Settings → Support → Reset).

For smartphones:

1. Open Settings → System → Resetting settings.
2. Select Reset Network/Display Settings (without deleting data).
3. For a complete reset, use Settings → About phone → Reset to factory.

If you've used ADB-commands or edited system files, return standard values:

adb shell settings delete global stay_on_while_plugged_in

Tips for optimizing energy consumption without sleep

Sleep deprivation can increase battery or power consumption, and to minimize the negative effects, follow these guidelines:

• 🔋 On smartphones, use a dark theme and reduce the brightness of the screen to 50-70%.
• 📺 On TVs, activate Local Darkening (if any) instead of completely shutting down your sleep.
• ⚡ Turn off background activity of unnecessary apps in Settings → Annexes → Permits → Auto-start.
• 🔄 Regularly update the firmware in new versions MIUI Google TV Optimized energy consumption.

For Xiaomi TVs, it is also useful to set up an on/off schedule:

1. Go to Settings → Device → On/off timer.
2. Set automatic shutdown for the night (for example, from 1:00 to 7:00).
3. This will save energy without manual control.
