How to make sure the screen is not dim on Xiaomi: All ways to customize

Modern Xiaomi, Redmi and Poco smartphones are equipped with high-quality displays that consume a significant part of the battery power. It is to save power that developers implement aggressive energy saving algorithms that automatically turn off the backlight after a period of inactivity. However, in some situations, this functionality becomes an obstacle to comfortable use of the gadget. Users often face the need to leave the display on while reading, navigating or viewing information.

There are several proven methods to change the standard behavior of the system. MIUI You can extend the interval to a few minutes or turn off the timer altogether. It is important to understand that the constant operation of the matrix at high brightness can lead to accelerated burnout of pixels on the device. OLED-So the way we do this is to take a balanced approach to solving the problem.

In this article, we will take a closer look at all available standard system tools and third-party solutions, and we will look at how to configure automation to turn off the screen only when you really need it, which will allow you to avoid unnecessary manipulation of power buttons and make interaction with the device more smooth.

Standard sleep timer settings in MIUI and HyperOS

The basic tool for managing display activity time is the built-in settings menu, where the user can choose from preset time slots. The system offers options from 15 seconds to 10 minutes, which covers most use cases. To access these parameters, you need to go to Settings → Screen and brightness → Sleep mode.

The choice of a particular value depends on your habits. If you read long text from the screen often, it makes sense to set the maximum value. In standby mode, the device will continue to lock, but the time span will be increased. This is a trade-off between convenience and energy consumption.

It's worth noting that some firmware versions have a maximum staffing limit of 5 minutes, a limit that's been put in place by the company's engineers to protect the battery, and if you need more time, you'll have to look for alternatives, which we'll talk about later, but for most things, standard functionality is good enough.

• 📱 Go to the settings menu via the gear in the notification curtain or on the desktop.
• ⏱ Find the "Sleeping Mode" item in the screen settings section.
• 🔋 Choose the optimal time from 30 seconds to 10 minutes.

These changes are immediate, so you don't need to restart the device or apply any additional settings, and the system will start counting the time to lock again after each touch.

Use of the “Do Not Turn Off Screen” Mode for Developers

For those who want to keep the screen from going out at all while the device is connected to charging, there is a special feature in the developer menu called Stay Awake, which is primarily designed to test applications, but is actively used by ordinary users to create stationary displays or clocks.

To activate this feature, you first need to unlock access to the hidden menu. → About the phone and quickly press 7 times on the item "Version" MIUI» or "Version" OS». After the notification that you have become a developer, the main settings menu will appear a new section “Additional” or “Extended settings».

⚠️ Warning: Activation of Developer Mode opens access to critical system settings. Be careful not to change settings that you do not know the purpose of, so as not to break the Work of the device tab.

Inside the developer menu, find the "Don't Turn Off" switch. Activate it. Now that the smartphone is connected to the power source via USB or an adapter, the display will burn constantly. Once you turn off the cable, the standard lock timer will start.

This method is ideal for using a smartphone as a navigator in a car if it is connected to a charge, or as a digital clock on a desk. However, remember that a static image on a screen for a long time can cause a “burn-in” effect on the car. AMOLED-matrix.

Customize exceptions and smart features

The MIUI shell offers a number of smart features that can indirectly affect screen behavior. For example, Keeping the screen on while looking uses a front-facing camera and sensors to detect the presence of a user. If the phone "sees" you're looking at it, it won't go out even if the timer has expired.

Also worth paying attention to the settings of specific applications. In some cases, the system can automatically extend the display time for certain programs, such as navigators or video players. Check the settings in the section Security → Battery → Application settings. Here you can prevent the system from "killing" background processes, which sometimes helps to keep the screen active.

Also, in the Second Space theme or guest mode, the timer settings may differ from the main profile. If you use these features, check the settings in each profile separately, this is especially true if you hand over the phone to children to watch cartoons.

💡

The “Seeing Screen” feature consumes additional CPU and camera resources, which can reduce battery life by 5-10%.

Remember that having a protective glass or film covering the proximity sensor can disrupt smart functions, in which case the phone will assume that it is in your pocket, and may lock ahead of time or, conversely, do not go out when you bring it to your ear.

Third-party screen management applications

If the standard features are not enough, the Google Play store offers a variety of utilities for flexible backlight management. Apps like Keep Screen On, Caffeine or Screen Alive allow you to create profiles. You can set the rule: "If Chrome is running and the charge level is above 20%, do not turn off the screen."

These programs run on top of the system and intercept commands to lock, and they often have a widget in the notification curtain that allows you to turn on or off the eternal screen in a single click, which is much more convenient than going into deep system settings each time.

When selecting an application, pay attention to the permissions it requests. The program needs access to a power management system to work properly. Also check reviews, as some utilities may contain intrusive advertising or are poorly optimized for Snapdragon and MediaTek processors.

Using third-party software is always a balance between functionality and security: Try to choose applications with a lot of installations and high ratings, avoid little-known utilities that require suspicious permissions to access contacts or files.

Automation through scripts and macros

Xiaomi smartphone owners can use the built-in Scripts app (or third-party counterparts like MacroDroid) to create complex algorithms. You can create a script: "When Home is connected to the Wi-Fi network and YouTube is running, set a 30 minute sleep timer."

This approach allows you to automate the process without constant manual intervention, and the phone will understand the context and apply the necessary settings, and this is a top-down aerobatics setup that makes the use of the gadget truly personalized.

To create a script, go to Tools → Scenarios. Press + to create a new rule. Select a trigger (start condition) and an action (change screen settings). The system allows you to combine many conditions, including time of day, location and charge level.

Automation is especially useful for people with disabilities or for those who use a smartphone in specific workflows where constant screen control is not possible.

Problems with the proximity sensor and their solution

Sometimes users complain that the screen goes out on its own, even when the timer settings are set to maximum, often because of a malfunction or contamination of the proximity sensor, which is located at the top of the screen, usually next to the speaker.

If you get dust, fat, or if you use a thick protective glass with a black bezel over the sensor, the phone will think it's in your pocket or pressed against your ear, and the screen will go out instantly whenever you touch the top of the display.

⚠️ Warning: Before contacting the service center, try to thoroughly wipe the top of the screen with an alcohol wipe. In 80% of cases, the problem is solved by a simple cleaning.

You can check the sensor through the engineering menu. Type ##6484## in the phone book (not all versions) or use the Testing app in the toolbox. Choose the proximity sensor test and cover the top of the screen with your hand - the reaction should be instantaneous.

If the sensor is in good working order but the problem persists, it is possible that the conflict is caused by a third-party application that has the right to block other windows.

The optimal setup is balance: use a standard 2-5 minute timer for everyday tasks and activate the “Do not turn off screen” mode only when necessary through the developer settings or scripts.
