How to keep the screen on your Xiaomi phone

Modern Xiaomi smartphones are equipped with bright AMOLED or LCD displays that provide excellent readability, but consume a significant part of the battery. Users often face a situation where it is necessary that the image remains active while navigating, reading recipes or viewing data, but the system automatically locks the device after a short period of time. This behavior is a standard energy saving feature built into the MIUI or HyperOS shell, but it is easily customized to the needs of the owner.

In this article, we will discuss in detail all the available methods to change the logic of backlighting. You will learn how to increase the standard interval to the maximum value, activate specialized modes for constant glow and what to do if the settings are reset by themselves. Understanding these mechanisms will help you adapt the operation of the smartphone for specific use cases without the need to install third-party software.

It is worth noting that the constant burning of the screen can lead to accelerated wear of the matrix, especially on panels such as AMOLED, where there is a risk of burning out static interface elements, so it is important not only to turn off the timer, but also to do this consciously, using built-in protective mechanisms of the system that minimize the potential harm to the display during prolonged active operation.

Setting up a standard lock timer

The basic tool for managing display activity time is a built-in timer located in system settings. To change its value, you need to go to the Settings menu, then select the Screen and Brightness section and find the Sleep Mode item. Here is a list of available intervals, which range from 15 seconds to 10 minutes, depending on the software version and model of your Redmi or Poco device.

Choosing the maximum value in this menu is the easiest way to extend screen life without using third-party apps. However, it is worth considering that even a maximum delay of 10 minutes may not be enough for some tasks, such as reading long texts or using the phone as a desktop clock.

It's important to understand that some apps may have their own timer settings that override system values. For example, navigators or reading programs often force the screen to be turned on while the navigation process is running or the book is open. If you notice that certain programs don't go out longer than usual, check their internal power saving settings.

• 📱 Standard path: Settings → Screen and brightness → Sleeping mode.
• ⏱️ The maximum waiting time is usually 10 minutes.
• 🔋 Increased timer directly affects the speed of battery discharge.

⚠️ Attention: Setting a maximum waiting time (10 minutes) in combination with high brightness can lead to overheating of the device body during prolonged stay in the case or under direct sunlight.

If the standard time range isn’t enough, consider the more specialized features that Xiaomi developers have for specific use cases, which are often hidden in additional menus or activated through special actions, which we’ll talk about in the next sections.

Always-on Display Mode for Constant Lighting

For devices equipped with AMOLED arrays, the most effective solution is the Always-on Display (AOD) function, which allows you to display time, date, notifications and images even when the phone is in sleep mode, while consuming minimal energy. Unlike normal mode, where the entire screen is on, AOD only has individual pixels active, which prevents burnout and saves charge.

To activate this feature, go to Settings, select the Screen is always on and lock screen (or just lock screen) and turn on the switch Screen is always on. Modern versions of HyperOS have a variety of styles available, including digital watches, analog dials and even live wallpaper that can work in the background. This is ideal if you need the phone to visually not “extinguish” completely.

It is also possible to adjust the AOD schedule so that it only activates at certain times of the day, such as work hours or at night, allowing you to flexibly manage power consumption without sacrificing convenience, and it can shut down automatically if the phone is in your pocket or bag for a certain time, thanks to the proximity sensor.

It is worth noting that on some budget models with LCD This function may not be available or work in limited mode, since the technology requires elemental backlight control, available only on the screen. OLED-Owners of such devices should pay attention to the alternative methods described below.

• 🕰️ AOD displays information on a screen that is off without full activation.
• 🎨 Different styles are available: clock, calendar, GIF-animation.
• 📅 You can set up the switch-on schedule to save battery.
• 📉 Nana LCD-The screen function may be unavailable or limited.

The function “Do not turn off the screen” in read mode

There's a unique feature called Read Mode in the MIUI and HyperOS shell that was originally designed to make text content comfortable, but it has the potential to stop turning off automatically when a certain type of mode is activated while the reading app is open, and it's the perfect way to turn your smartphone into an e-book without the risk of being blocked suddenly.

To use this method, open Settings, find the Screen and Brightness section, and select Read Mode. Here you need to switch to the Full Screen option (or similar, depending on the software version). Once this mode is activated, when you run supported applications (for example, browser, Chrome, Kindle, Mi Video), the system will automatically support the backlighting on.

The advantage of this is that it's selective: the screen won't burn all the time throughout the system, which saves the battery, but it will stay active in exactly the applications where it's needed. You can manually add any programs to the exception list so that they trigger this mode, which is a more flexible solution than changing the lock timer globally.

⚠️ Note: When using full screen mode in reading apps, it is not recommended to leave the phone at maximum brightness for a long time, as this can lead to uneven wear of the pixels.

If you use your phone for navigation or as a dashboard, this method can also be useful. Just add a navigator or monitoring app to your reading mode list and the screen will burn as long as it takes for the trip. Remember that in this mode the color gamut can be changed, which is not always convenient for maps.

Using Developer Mode to Turn Off Timer

For advanced users who want to ensure that the screen never goes out (as long as the phone is connected to charging or online), there is a hidden Developer Mode menu, which is the most radical, since it forcibly cancels the system sleep timer. To get into this menu, you need to quickly click on the MIUI version number in the About Phone section several times.

Once you activate the developer menu, go to Advanced Settings → For Developers. Here you need to find the item Do not turn off the screen (or Stay awake). Activating this switch ensures that the display will burn as long as the device is connected to the power source via USB or adapter. This is ideal for using the smartphone as a stationary monitor or smart home control panel.

However, this feature requires caution, because the screen will not go out at all, the risk of burning out static elements of the interface (status panel, navigation buttons) is extremely high, and it is recommended to use this method only in combination with programs that periodically change the picture, or on screens where the risk of burnout is minimal.

Also, activation of the developer mode can make available other hidden parameters, changing which without understanding their purpose can lead to unstable operation of the system.

• ⚙️ Path: Settings → Advanced settings → For developers.
• 🔌 The function only works when connected charging.
• 🚫 Completely ignores the standard lock timer.
• 🔥 High risk of burnout of static interface elements.

Third-party screen management applications

If you don't have the built-in capabilities of Xiaomi, Google Play offers a variety of customized apps that take over the backlighting. Programs like Keep Screen On, Caffeine or Screen On create a temporary blocker on top of the system to prevent sleep, and they often have handy widgets to quickly turn the function on and off.

The main advantage of these apps is flexibility. You can set up profiles, for example, the screen doesn't go out just when YouTube is running, or only when the phone is connected to the Wi-Fi network of the home router, which allows you to automate the process and not worry about manually setting up every time. Some applications also know how to simulate a light touch screen (Auto Clicker) to fool the system's activity timer.

However, using third-party software has its downsides: applications like this require permanent permissions to overlay other windows and work in the background, which can conflict with the aggressive MIUI battery optimization system. You will have to manually prevent the system from "killing" the application process in the background, otherwise it will stop working in a few minutes.

When choosing an app, pay attention to reviews and the date of the last update. Older programs may not work correctly on newer versions of Android and HyperOS, causing interface lags or increased power consumption even when turned off. Always check whether you really need a separate application, or can do with built-in features.

Problem Solving: The screen goes off on its own

There are situations where the user has set all the settings, but the screen still goes out prematurely or behaves unpredictably, often because of a proximity sensor that can be closed with a low-quality protective glass or contaminated, if the phone "thinks" it is in your pocket or ear, it forcibly extinguishes the screen, ignoring the timer settings.

Another common problem is the function of the Adaptive brightness.In an attempt to save energy, Xiaomi algorithms can dramatically reduce brightness to a minimum, creating the illusion that the screen is out, even though the backlight simply works at minimal values.

It's also worth checking for system updates. Older versions of MIUI have had bugs where a lock timer resets after leaving a particular application. Updating to the current version of HyperOS or a security patch often resolves such software errors. If the problem persists, try resetting the screen to factory settings.

💡

If the screen goes out in the navigator, try to enable the option "Disable sleep mode" inside the map application itself (Yandex.Navigator, Google Maps), as their settings take priority over system ones.

In rare cases, the cause may be a hardware malfunction, such as a display plume or a power controller, if the screen goes out and immediately lights up again, or goes out at a certain angle of the phone, this may indicate poor contact, in which case software methods will not help, and you will need a diagnosis in the service center.

• 🧹 Wipe the top of the screen from contamination (approximation sensor).
• 💡 Turn off auto-brightness to check backlight stability.
• 🔄 Update maps and navigators to the latest version.
• 🛠️ Check the integrity of the protective glass over the sensors.
