Owners of modern Xiaomi smartphones often face a situation where the display goes out too quickly, preventing comfortable reading or viewing content. Standard power saving settings MIUI and HyperOS by default limit backlighting time to maintain battery power. However, for many users, this compromise becomes a source of constant discomfort, forcing them to constantly touch the screen or look for a charger.
Fortunately, the Chinese manufacturer’s Android shell system provides flexible tools to control this setting. You can set your own shutdown timer or activate special modes that make using the gadget more convenient. In this article, we will discuss in detail all the available ways to extend the life of the screen, including hidden functions and technical nuances of AMOLED and IPS matrixes.
Before making changes, it’s important to understand the difference between simply increasing the timer and using advanced features like Always On Display. Failure to set up can lead to accelerated wear on the matrix or the appearance of image artifacts. We’ll look at safe methods to help you find a balance between device autonomy and visual comfort.
Standard timer settings in MIUI and HyperOS
The basic way to manage display time is built directly into the system settings menu, and this is suitable for most users who simply need to increase the interval to the maximum standard value. To access these settings, you need to go to Settings → Screen and Brightness → Sleeping Mode. Here you will see a list of available time slots.
Usually, the standard set offers options from 15 seconds to 10 minutes. The specific value depends on your smartphone usage habits. For example, reading e-books will be optimal for a value of 2-5 minutes, whereas for navigation it is enough for 30-60 seconds. HyperOS may differ slightly in the location of the points, but the logic remains the same.
It's worth noting that some low-end models may have limited maximum time options, due to the battery's features and the manufacturer's energy optimization, and if you don't have a standard maximum, you'll have to resort to more advanced methods, which will be discussed below.
If you often forget to lock your phone manually, the screen will burn longer than necessary, wasting energy, so it is recommended to choose a value that is comfortable for your use case, rather than just setting the maximum.
Use Always On Display for Permanent Glow
For devices with AMOLED arrays, Xiaomi offers Always On Display (AOD), a technology that allows you to display important information such as time, date and notifications even when the phone is locked. Unlike normal mode, AOD does not completely turn off the screen, but uses only a fraction of the pixels, which saves energy.
This function is activated via the Settings menu → Screen and brightness → Always On Display and lock. Here you can choose the display style, schedule and activation conditions. For example, you can set the AOD to turn on only when you receive a notification or at a certain time of day. This is a great way to keep the screen alive without the risk of burnout.
⚠️ Warning: Always On Display is available only on smartphones OLED/AMOLED On devices with screens. IPS This function is software blocked or absent, since the technology does not allow to highlight individual pixels without turning on all the backlights.
Using AOD is a trade-off between aesthetics and battery consumption. Although the technology is optimized, it still consumes energy. If you're critical to maximize autonomy for days without charging, it might be worth using this mode selectively or on schedule.
💡
Use dark themes for Always On Display – on AMOLED screens, black pixels are completely turned off, which significantly saves battery life.
Extended Features Through Engineering Menu
For power users who don't have the standard constraints, there's a hidden settings available through an engineering menu that allows you to change system settings, including minimum brightness and specific timers that are not available on a regular menu, but this section requires caution.
To get into the engineering menu, open the Phone app and enter a special code, such as ##6484## (code may vary depending on the model and firmware version). The CIT (Customer Interface Test) menu that opens can find display tests where additional settings are sometimes available. However, direct access to changing the sleep timer through the code is often closed in new versions of MIUI.
A more effective method for advanced users is to use ADB (Android Debug Bridge), which by connecting a smartphone to a computer, you can send a command to change the system value of the timer, which requires the inclusion of debugging over USB in the Developer Menu.
adb shell settings put system screen_off_timeout 60000In this example, the team sets the fade time to 60,000 milliseconds (1 minute). You can substitute any value. However, be careful: setting too high values can cause the screen to burn constantly if the proximity sensor or smart lock fails.
Risks of using ADB teams
Third-party screen management applications
If the built-in tools fail to achieve the desired result, applications from the Google Play store come to the rescue. There are many utilities that can force the screen to be turned on or create flexible backlight management profiles. Popular examples include Keep Screen On, Screen On Pro and analogues.
These apps run on top of the system and use permissions to access the corresponding Android APIs. They can turn on the screen when you run a particular application, when you connect a charger or on a schedule, which gives the user much more control than standard settings.
- 📱 Keep Screen On – a simple app with minimal settings, perfect for reading.
- ⚙️ Screen Control – allows you to create complex scripts and profiles for different situations.
- 🔋 Battery Saver – some “optimizers” have a screen control function as part of a set of tools.
When installing third-party software, pay attention to the permissions requested. The app does need access to screen control, but the contact or location request may be suspicious. Always check other users' ratings and reviews before installing.
☑️ Checking before installing applications
Comparison of lighting control methods
To make it easier for you to choose the right method, we have prepared a comparison table of basic methods, which will help you assess the pros and cons of each option depending on your needs and device model.
| Method | Difficulty | Impact on the battery | Availability |
|---|---|---|---|
| Standard settings | Low. | Moderate. | All models. |
| Always On Display | Low. | Low (AMOLED) | Only AMOLED |
| Engineering Menu / ADB | Tall. | Depends on the settings. | All models (at risk) |
| Third-party annexes | Medium | High. | All models. |
As you can see from the table, for most users, the optimal solution is a combination of standard settings and AOD functions. The use of engineering menus is justified only in specific cases when fine tuning for specific tasks is required.
⚠️ Warning: Prolonged high-brightness screen exposure can cause the device to overheat. If you use your smartphone to navigate or read in the bright sun, monitor the temperature of the case.
Problems with the proximity sensor and their solution
Sometimes users complain that the screen goes out on its own, even if a long fade time is set, often a faulty or contaminated proximity sensor is the culprit, located at the top of the screen and can respond to a protective glass or case.
To diagnose the problem, you can use an engineering test: enter the code ##6484##, select "Proximity sensor" and hold your hand to the top of the screen. The indicator should change its value. If the reaction is not present or chaotic, you need to calibrate or clean it.
Calibration can be done through the same engineering menu or with special applications from the Play Market, and it is also worth checking whether the protective film covers the sensor area, in some cases, simple resetting to the factory settings helps if the problem is caused by a software failure.
💡
If the screen goes out before the timer is set, 90% of the time the problem is in the proximity sensor or the protective glass, not in the time settings.
The effect of matrix type on screen settings
Understanding your display type is critical to getting the right setup. Xiaomi smartphones come with two main types of arrays: IPS and AMOLED. The former use constant backlight, the latter use self-luminous pixels. This fundamentally changes the way we think about energy saving.
Nana IPS-In the case of screens, increasing the backlight time always leads to a linear increase in power consumption. There are no "free" ways to hold a picture, except to reduce the brightness. AMOLED Black doesn’t consume energy at all, which opens up opportunities for dark themes and Always On Display without seriously damaging autonomy.
In addition, OLED arrays are at risk of burning out static interface elements, so the system can forcefully limit the display time of a static image or slightly shift the image, which is normal behavior aimed at extending the life of the display.
