How to turn off the screen on Xiaomi: the complete guide

Modern Xiaomi smartphones have powerful AMOLED and IPS displays that consume a significant amount of energy when used actively. To keep the battery power, the MIUI system and its current HyperOS shell automatically extinguish the screen after a certain period of inactivity. This is the usual behavior of the device, but in some scenarios it becomes extremely uncomfortable for the user. For example, when reading long articles, watching recipes in the kitchen or showing presentations, the constant need to unlock the gadget is annoying.

Fortunately, the Android operating system provides flexible tools to manage your sleep timer. Owners of Redmi and POCO devices can change standard intervals or completely disable automatic matrix quenching. In this guide, we’ll take a look at all the available ways, from basic system settings to using hidden features for developers, to keep your screen on as long as necessary.

It is worth noting that completely turning off the timer can lead to accelerated battery consumption and potential pixel burnout on older types of matrixes. So it is important to understand the difference between extending the time to sleep and completely blocking this process. We will look at safe methods of setting up that will avoid negative consequences for the hardware of your smartphone.

Standard timer settings in MIUI and HyperOS

The first and most obvious way to control screen sleep is through the standard settings menu, where users can choose the time period after which the device will go to sleep. By default, this setting is often set to 30 or 60 seconds, which is the optimal balance between convenience and energy savings. However, for specific tasks, these values can be changed.

To find these settings, you need to go to Settings and select Screen and brightness. In the menu that opens, you should find the option Sleep Mode (or "Screen Time Out"). When you click on it, you will see a list of available intervals. Depending on the firmware version, the list can range from 15 seconds to 10 minutes.

Selecting the maximum value in the standard menu is the safest method, without requiring third-party software, which ensures that the screen does not go out too quickly, but still turns off if you forget to lock the phone, which saves battery life. If you need to keep the screen on all the time, standard means can not do this, and additional solutions will be required.

• 📱 Go to Settings. → Screen and brightness for access to power management.
• ⏱ Select Sleep mode to change the time interval.
• 🔋 Set the value of "10 minutes" or "Never" (if available in your version of the software).

⚠️ Warning: Setting a maximum waiting time without supervision of the device can lead to a complete discharge of the battery and overheating of the case, especially in direct sunlight.

Using Developer Mode to Turn off Sleep

For more advanced users who need to keep the screen from going out at all (Never mode), there is a hidden engineer menu. Android has a special debugging feature that forcibly prevents the system from going to sleep while charging the device, ideal for those who use a smartphone as a desktop clock, navigator in the car or a smart home control panel.

To activate this feature, you first need to unlock access to the developer menu. → About the phone and find the line version MIUI (or OS). You need to press this line quickly. 7-10 Once in a row, until you notice that you have become a developer, and then a new section will appear in the settings menu. → Advanced settings → For developers.

Inside the developer menu, you scroll down to Monitor or Debug, and there's a Stop Awaken switch, which means that as long as the smartphone is connected to a power source (USB or wireless charging), the array will burn all the time, a critical feature for continuous monitoring scenarios.

Remember, this setting only works when the charger is connected, and once the cable is disconnected, the standard timers you set up before will come into effect, a protective measure to prevent the device from accidentally discharging in your pocket.

• 🔓 Make 7 quick taps by build number in the About Phone section".
• 🛠 Find the "Developers" menu in the advanced system settings.
• ⚡ Activate the "Do not turn off the screen" switch to work while charging.

⚠️ Warning: Prolonged screen operation at maximum brightness during charging can cause significant heating of the device, which will adversely affect the chemical composition of the lithium polymer battery.

Third-party screen management applications

If you don't have the built-in capabilities of Xiaomi, you can use specialized apps from the Google Play store. There are many utilities, such as Keep Screen On, Caffeine or Screen On, that allow you to create screen management profiles, which run on top of the system and can force you to block your sleep timer on a schedule or when you run certain apps.

The way these apps work is to make it temporary to stop going to sleep, and some of them add a button to the Quick Notifications panel, which makes it very convenient to control, so you can turn on the Always On mode only when you need to, and turn it off with a single touch, without digging into the depth of the settings.

However, when using third-party software on the shell MIUI/HyperOS Often, there are problems with aggressive battery optimization, the system can force the application's background process to close, considering it harmful or energy-consuming, and to avoid this, you need to manually configure permissions and auto-runs for the selected utility.

It is important to choose applications that are highly rated and downloadable, as they require special permissions at the system level, and low-quality software can, on the contrary, increase energy consumption due to poor code optimization.

• 📥 Download a proven app, such as “Keep Screen On” from Google Play.
• 🔋 Allow auto-start and remove battery restrictions in security settings.
• 🎛 Use a widget or button in the curtain to quickly turn on the mode.

Blocking the screen in specific applications

Often users need to keep the screen from going off in just one particular application, such as a navigator, a reader, or while watching videos. In such cases, global timer shutdown is impractical. Many modern applications have a built-in "keep the screen on" feature that can be found in their own settings.

For example, popular readers like Moon+ Reader or FBReader have a “Do not turn off screen” option in the display settings section. In navigation applications (Yandex.Navigator, Google Maps), the screen usually does not go out during the default route, and checking the internal settings of frequently used programs is the first step to take before installing additional software.

If the app doesn't have this feature, you can use App Pinning, which is an Android feature that allows you to lock one app onto the screen, prevent it from leaving, and in some configurations, prevent it from falling asleep. → Passwords and security → Confidentiality → Special facilities → Fixing in the window.

Once this function is enabled, by opening the menu of running applications (swipe up and hold), you can click on the app icon from above and select "Secure." While the application is fixed, the system will behave differently, prioritizing its operation.

• 📖 Check the settings of the application itself (Section "Screen" or "Display").
• 📌 Use the “Fixing in the window” function to fix a specific application.
• 🚫 To exit the fixed mode, press the buttons "Back" and "Recent" at the same time.

Comparison of screen sleep management techniques

The right method depends on your specific goals and your smartphone model. Each of these methods has its advantages and disadvantages. Standard settings are safe but time-limited. Developer mode is efficient but requires charging. Apps are flexible but consume resources.

The table below provides a detailed comparison of the characteristics of each method so that you can choose the best option for your situation.

Burnout problems and display safety

Using the features of the screen on a permanent basis, especially on smartphones with AMOLED arrays (which are installed in the flagship models of Xiaomi and POCO), you need to remember the risk of pixel burnout. Burnout is an irreversible process of degradation of organic LEDs, in which static traces of the interface remain on the screen.

Modern shells have protection against this phenomenon by changing the position of static elements or slightly shifting the image. However, forced to keep the screen on at high brightness for many hours reduces the effectiveness of these protections to a minimum. If you need to use the phone as a display, it is recommended to reduce the brightness to a minimum comfortable level.

💡

To prevent burnout with a long screen on, use dark themes and reduce brightness, you can also turn on color inversion if the application allows the load on the subpixels to be distributed evenly.

Also, the temperature is important. A running display is a heat source. When combined with charging (if the developer mode is used) and the processor, the temperature of the case can reach critical values, in which case the system can force the brightness to decrease or even turn off the display to protect the internal components.

⚠️ Warning: When leaving the screen on for a long time, make sure the device is in a well-ventilated place and not covered with cloth or other materials that prevent heat transfer.
