How to Remove Screen Reduction on Xiaomi: The Complete Guide

The problem of suddenly quenching a display at the most inopportune moment is familiar to many smartphone owners, which is annoying when reading long articles, browsing recipes in the kitchen or studying maps while navigating. Standard MIUI and HyperOS settings often limit the maximum waiting time to two minutes, which is not always convenient.

However, there are proven ways to get around these limitations and customize the device to your needs, and in this guide, we will discuss the usual methods of increasing the timer, using hidden developer functions, and third-party utilities for full control of the screen.

It's important to understand the difference between software locking and hardware problems. If the screen goes out immediately after touching or changes brightness randomly, it may be the proximity sensor or the power button sticking.

Standard setting of the lock timer

The easiest and safest way to increase screen time to damp is to use the built-in settings. Android’s basic algorithm uses energy savings, so the default timer is 30 or 60 seconds.

To change this setting, you need to go to the settings menu. The path may vary slightly depending on the version of the shell, but the logic remains the same for all Xiaomi, Redmi and Poco devices.

• 📱 Open the Settings app on the main screen.
• ⚙️ Go to the Screen and Brightness section (or just the Screen).
• ⏱ Find the item Sleeping mode or screen timeout.
• ✅ Choose the maximum value available, usually 2 minutes or 5 minutes.

⚠️ Attention: Setting the maximum timer value significantly speeds up battery discharge, especially if used AMOLED-high-frequency display.

If you don't have the time you need on the list of options, it means that the manufacturer has severely limited the choice for battery safety, in which case the standard methods will not be able to increase the time.

💡

The maximum screen time without action in the standard menu is limited to 5-10 minutes to prevent the matrix from burning out and overheating the device.

Use of the developer mode

For more advanced users, there is the possibility of accessing hidden system settings. The developer menu allows you to change the settings that are hidden from the average user, including some aspects of display management.

Activating this mode requires you to perform sequential actions to click on the build number, which does not violate the warranty, but requires caution when changing unknown parameters.

• 🔢 Go to Settings. → The phone.
• 👆 Press quickly. 7-10 once-point version MIUI (or OS).
• 🔓 Enter the unlock password when the activation notification appears.
• ⚙️ Return to the menu Additional → For developers.

Inside the developer menu, you should pay attention to the section related to animation and display. Although there is no direct "never turn off screen" setting, you can turn off some of the power saving features that aggressively extinguish the display.

Applications to prevent blocking

If system constraints aren't enough, specialized apps from the Google Play store come to the rescue, and they work on the principle of emulating a light touch or simply prohibit the system from going to sleep.

There are many free utilities that hang in the background and monitor the status of the screen, and they are especially useful when the phone is used as a navigator or dashboard.

• 🚀 Caffeine – Adds a button to the notification curtain to quickly turn on the “Do not go out” mode".
• 🔦 Keep Screen On – allows you to set time for specific applications.
• ⏱ Screen Alive emulates micro-movements to make the system think the phone is being used.

When installing such programs, be sure to check the permissions. To work correctly, they often require permission to “mask over other windows” and access to special features.

💡

Use the Digital Well-Being feature in your Android settings to limit the time you use your blocking apps and not waste your battery.

Always on Display and its configuration

Always On Display (AOD) technology allows time, date and notifications to be displayed on a screen that is off, not exactly a disabler, but a useful alternative for those who want to see information all the time.

This feature is only available on smartphones with AMOLED It's a matrice, because it allows you to highlight individual pixels without harming the resource of the screen. IPS-This option is usually not available on screens.

To set up, go to Settings → Wallpaper and Personalization → Always On Display. Here you can choose the display style and schedule.

⚠️ Note: Always on Display is about 1-3% Battery charge per hour, which can be critical when using your phone during the day.

It is recommended to set the AOD schedule, for example, from 8:00 to 23:00, so that the screen does not burn and does not interfere with sleep at night, and also saves charge.

Solving proximity sensor problems

A common cause of sudden screen quenching during a conversation or reading is a faulty or contaminated proximity sensor located at the top of the smartphone, often next to the speaker.

If dust, fat or a protective film with an irregularly shaped cutout is put on the sensor, the system may think that the phone is held to the ear and extinguish the screen.

You can use the engineering menu to diagnose the problem, enter the ##6484## code in the phone app (not all models) or use the MIUI Tester app.

In the sensor test, check the screen's response to the upper body being closed by your hand. If the screen goes out instantly and doesn't light up after the hand is removed, calibration or cleaning is required.

To make it easier for you to choose the right method, we have prepared a comparative table of the main ways to control the screen timer.

The choice of method depends on your goals. For a one-time reading of documents, standard settings will suffice, and third-party applications will be better suited for using a smartphone as an information panel.
