How to increase screen activity time on Xiaomi Redmi

Modern Xiaomi Redmi smartphones are equipped with energy-efficient OLED and IPS arrays that are designed to save battery power. However, often users are faced with a situation where the display goes off too quickly, interrupting reading or viewing content. A standard timeout of 15 or 30 seconds may not be enough to comfortably use the device in certain scenarios.

MIUI and the new HyperOS have mechanisms that limit backlighting time without user action, to prevent pixel burnout and maintain autonomy, but can be flexibly configured if needed by extending the available limits or by turning off automatic locking altogether.

In this guide, we’ll take a look at all the available methods for increasing timeouts, from basic system settings to hidden engineering menus, and learn how to bypass standard interface constraints and keep the screen active for as long as you need.

Standard timeout settings in MIUI and HyperOS

The basic way to change the waiting time before locking is available in the settings menu of any Xiaomi smartphone. The path to the desired setting may vary slightly depending on the version of the shell, but the logic remains the same. Usually the system offers a choice of fixed intervals: 15 seconds, 30 seconds, 1 minute, 2 minutes and so on up to 10 minutes.

To access these options, you need to go to Settings, then select Screen and brightness (or just Screen). In the list that opens, look for the Sleep Mode option. Clicking on it will open the time selection menu. It is important to note here that the maximum standard value is often limited to 10 minutes, which is not always convenient.

• 📱 Go to the main settings menu of your Redmi.
• 🔍 Find the section responsible for display parameters and brightness.
• ⏱ Select "Sleeping Mode" or "Screen Time Out".
• ✅ Set the desired time from the proposed list.

It is worth considering that some energy-saving profiles can ignore manual settings and force you to reduce screen time. If you activate Ultra-Energy Saving or Charge Saving mode, the system will tend to extinguish the display as quickly as possible.

Use of "Do not turn off" mode when charging

If your goal is to use your smartphone as a desktop clock, a navigator or a smart home control panel, a standard 10 minute timeout will not be enough, in which case the ideal solution is the “Do not turn off” feature, which is available on the developer menu and allows the screen to burn indefinitely while the device is connected to the power source.

To activate this feature, you first need to unlock the developer menu. To do this, go to Settings → About Phone and quickly press 7 times on the MIUI Version (or OS Version). After the notification that you have become a developer, go back to the main settings menu, select Additional → For Developers. At the bottom of the list, find the Do Not Turn Off switch and activate it.

⚠️ Warning: Constant display operation at maximum brightness when connected to the charger can lead to overheating of the battery and accelerated degradation OLED-Matrices. Use this function only when necessary.

This feature is especially useful when showing presentations or using a smartphone as a stationary terminal, but it is worth remembering that a static image on the screen for a long time is dangerous for matrices. AMOLED, The Redmi models are used in the flagship models. IPS-screens are less critical, but the risk of burnout or residual images still persists.

💡

Use dark wallpaper and minimalist widgets if you plan to keep the screen on for a long time, which will reduce the load on the matrix and reduce the heating of the case.

Expanding the time list through the Engineering Menu

The regular settings menu often hides the possibility of setting an arbitrary time, limiting the user to presets. However, there is a hidden mechanism in the MIUI shell for entering an exact value in milliseconds, which allows you to set an activity time that is not on the standard list, for example, 45 seconds or 3 minutes.

This method will require access to ADB (Android Debug Bridge) or special settings launcher applications, since the direct input field in the interface is hidden. But there is an easier way through hidden code if it is supported by a particular firmware version. Type ##6484## into the dialer to enter the engineering menu, but direct access to the timer is rare.

A more reliable method is to use the ADB command to set the system value. Connect the phone to your computer, enable debugging over USB, and type in the command:

adb shell settings put system screen_off_timeout 120000

Here 120,000 is milliseconds (2 minutes) time. You can substitute any value. It's important to understand that once the device is rebooted, some models can reset that parameter to a factory value if it's hard-coded in the firmware configuration file.

• 💻 Connect your smartphone to a PC with installed ADB.
• 🔧 Put the debugging on. USB developer-menu.
• ⌨️ Enter the timeout setup command in milliseconds.
• 🔄 Check the result and fix the setting if necessary.

This technique requires a certain amount of technical literacy, but it gives you the maximum flexibility, and you can customize the screen to your needs, not just with the manufacturer's templates.

Third-party screen management applications

If system methods seem too complex or limited, Google Play apps come to the rescue. There are many utilities that can force the screen to be active or create their own timeout profiles for different situations.

One popular solution is the "Caffeine" app or its analogues, which are simple: they simulate a light touch of the screen or send a system signal of activity, preventing it from going to sleep. Other applications, such as "Screen Timeout", add a widget on the desktop, allowing you to change the lock time to any convenient one click.

Using third-party software has its own risks. Some optimizers may aggressively consume the battery even when the screen seems to be going out. In addition, applications with overlay rights over other windows can conflict with the MIUI interface, causing random taps or lock touch input.

Impact of Developer Mode and Debugging

There are many parameters hidden in the developer menu that affect display behavior. In addition to the "Do Not Turn Off" feature already mentioned, there are settings related to animation and rendering that indirectly affect the perception of activity time, for example, turning off animations can make the transition to sleep mode more sharp and noticeable.

And you should also look at the Stay Awake option that we've already looked at, but there are some less obvious settings, like "Show touch" or "Point pointer position," which can interfere with normal operation, but is sometimes used to test the touch layer, and make sure that these features are turned off if you're not debugging the interface.

Inexperienced changes to parameters associated with DPI or refresh rate can lead to unstable interface operation or even the need to reset settings.

⚠️ Warning: Do not change the values in the "Drawing" or "Hardware acceleration" section unless you are sure of the consequences.This may cause the system to freeze or the touchscreen to malfunction.

For the average user, only activate the function of preventing sleep while charging, the rest of the settings should be left by default to ensure the stability of the HyperOS or MIUI operating system.

Problems with the proximity sensor and autolock

Users often confuse screen timeout with autolock when approaching the ear. If the screen goes out while talking or watching video horizontally, the problem may not be the timing settings, but the proximity sensor. On Redmi smartphones, this sensor sometimes gets calibrated incorrectly or contaminated.

You can check the sensor through the engineering menu. Enter the code ##64663## (or select "Version" in the phone menu and click "Hardware Tests"). Select the "Proximity Sensor" test. Close the top of the screen with your hand - the value should change from 5.0 to 0.0. If this does not happen, you may need to calibrate or clean the speaker area.

There is also a Pocket Mode feature that locks the screen when the phone is in your bag or pocket to avoid accidental taps, and if this function is not working properly, the screen may go out too early or, conversely, not turn on when the device is removed.

• 🧹 Wipe the top of the screen from pollution and fat.
• 🛡 Check if the security glass is blocking the sensor.
• ⚙️ Turn off "Pocket mode" in the lock settings for the test.
• 📞 Conduct a sensor test in the engineering menu.
