Many users experience a situation where the smartphone screen goes out at the most inopportune moment. This can happen while reading long articles, viewing recipes in the kitchen or when showing a presentation. Standard system settings are often too aggressive, causing the device to go to sleep after 30 seconds or a minute of inactivity. Owners of Xiaomi, Redmi and Poco phones often look for a way to completely remove this restriction, so that the screen burns constantly.
However, completely disabling the lock function requires caution. A constantly burning display not only quickly discharges the battery, but also carries the risk of burning out pixels on AMOLED-matrixes. In this article, we will discuss all available methods for managing the sleep timer, including hidden settings and specialized applications. You will learn how to find a balance between convenience and saving the battery life of your gadget.
To start with, standard system tools can significantly increase the time to turn off the screen, but the "Never" option is often absent from the basic menu. This is done by manufacturers specifically to protect the device. However, there are workarounds. Below we will look at how to maximize the ability to customize MIUI or HyperOS to your needs without installing extra software.
Standard timer settings in MIUI and HyperOS
The first and most obvious step is to check the basic system settings. In shells from Xiaomi, time management to lock is in the display menu. Here the user can choose a fixed time interval. Usually available options range from 15 seconds to 10 minutes. For most use cases, this is quite enough.
To change the settings, go to Settings → Screen and Brightness → Sleep mode. In the list that opens, select the maximum value available. It is important to understand that even a maximum value of 10 minutes is not a complete shutdown. If you read a document or watch a video without touching longer than this time, the screen will still go out.
Some users find that their time list is shorter than others, depending on the device model and firmware version. On low-end models, Redmi or Poco, the list may be limited, while the flagship Mi series offers more flexibility, and the availability of options may also be affected by the power saving mode on.
- 🔍 Open the settings and find the "Screen and brightness" section".
- ⏱️ Click on "Sleeping Mode" or "Screen Time Out".
- ✅ Choose the maximum available time (usually 5 or 10 minutes).
- 🔋 Make sure that the energy saving mode does not block the changes.
It's worth noting that new versions of HyperOS may have changed the logic of the timer, and it's now smarter at analyzing the content on the screen, and if you're watching a video, the screen may not go out even when the timer expires, but for static images or text, the hard-timer rule remains in place.
Using Developer Mode to Turn off Sleep
If you don't have a standard 10 minutes, you can use the hidden menu for developers, and this section hides a useful feature called "Don't Turn Off the Screen," which ignores the sleep timer while charging the device, which is ideal for those who use a smartphone as a desktop clock or an information panel.
To activate this mode, you need to first turn on the developer menu. → About the phone and quickly press 7 times on the item "Version" MIUI" Or "OS version." Once you've been notified that you've become a developer, go back to the main settings menu, and look for "Additional" or "Extended Settings" where "Developers" appears".
⚠️ Warning: Enabling Developer Mode opens access to system functions that may affect the work stability tab. Do not change settings that are unsure of, except for the option "Do not turn off the screen".
Inside the developer menu, scroll down to the Debugging section. Find the "Don't Turn Off" (or "Stay Awaken") switch and activate it. Now, as long as the phone is connected to the charger over USB or network, the screen will burn forever, ignoring the timer settings. Once you turn off the charger, the standard timer will start.
This method is especially useful for in-car navigation if the phone is connected to a Power Bank, or for using the smartphone as a system control monitor, but remember that the display at high brightness when charging can cause the case to overheat.
💡
Use the “Do not turn off screen” function only when charging is connected to avoid deep battery discharge at the wrong time.
Applications for forced screen retention
When built-in tools are not enough, third-party apps from Google Play come to the rescue. There are many utilities that emulate touching the screen or simply block the transition to sleep mode, such programs are often called "Keep Screen On" or "Caffeine".
The way they work is simple: the app creates an invisible layer on top of all the windows, or periodically sends a signal to the system about user activity, which resets the inactivity timer. Popular options are Keep Screen On, Caffeine or Screen Alive, which weigh a little and do not require root rights.
But the nuances of installing these applications are that in the MIUI shell, an aggressive energy-saving system can kill the background processes of these utilities on its own, and in order for the application to work consistently, it needs to be added to the startup and remove the background limitations of the battery settings.
Let’s look at the main advantages and disadvantages of using third-party software:
- 📱 Allows you to turn off the screen without being tied to the charger.
- ⚙️ Flexible management: you can only enable a function for specific applications.
- 🔋 May consume extra battery power due to constant processor activity.
- 🛡️ Requires permissions in the system MIUI steady-work.
How to set up autorun for Keep Screen On?
Configuring smart functions and proximity sensors
Sometimes the problem with apparent autolocking is not the timer, but the sensors. Xiaomi smartphones have a proximity sensor that turns off the screen when you hold the phone to your ear or put your palm on it. Wrong calibration or dirt on the sensor can cause false positives.
It's also worth checking the Pocket Mode feature. If it's activated, the phone can lock from your bag or pocket, even if the timer hasn't expired. It's a safety mechanism against random taps, but sometimes it works too "feelingly." You can turn it off in Settings → Screen lock.
Another important aspect is the "Rise to Wake Up" function, which, on the contrary, turns on the screen when the device moves, and if you combine this with a short sleep timer, you can feel the backlights are unstable, and try to turn off the extra smart functions to isolate the cause.
| Function | Location on the menu | Screen impact | Recommendation |
|---|---|---|---|
| Sleep timer | Screen and brightness | Extinguishes the screen after a given time | Set the max value |
| Keep the screen down. | For developers | Blocks sleep when exercising | Insert for stationary use |
| Pocket regime | Screen locking | Blocking in the dark/pocket | Disable with frequent false positives |
| One-handed mode. | Additionally. | Can darken part of the screen | Check your gesture settings |
Calibration of the proximity sensor is a separate topic. If the screen goes out while talking or watching video horizontally, you may need to calibrate through an engineering menu. In the Phone app, type ##6484## and select the proximity sensor test. Follow the instructions on the screen to calibrate.
Solving screen quenching problems in specific applications
Often users complain that the screen goes out only in one particular application, for example, when reading in the browser or navigation, in which case the problem may not be in the global settings, but in the optimization of the application itself or the conflict of versions.
Check to see if the app itself has its own sleep timer on, and many readers, browsers and video players have internal settings that override the system, and it’s also worth updating the app to the latest version via Google Play or GetApps.
If the problem is observed in navigation applications (Yandex.Navigator, Google Maps), make sure that the navigation settings select the mode "Day" or "Night", and not "Auto", which can misinterpret the lighting and extinguish the screen.
⚠️ Note: If the screen goes out in only one application after the system update, try clearing the cache of that application. → Annexes → [Name of the annex] → Memory. → Clear the cache.
☑️ Diagnostics of screen problem
The influence of the theme of design and live wallpaper
Don’t discount the impact of visual design on display performance. Some third-party themes downloaded from Themes store may contain code errors that conflict with the system lock timer, especially with topics that have complex unlock animations.
Live wallpaper can also affect screen behavior. If the system decides that resource-intensive wallpaper overloads the processor, it can forcefully restrict background activity, which sometimes manifests itself in strange display behavior. Try switching to standard static wallpaper and the theme "Classic" to rule out this factor.
In rare cases, reinstalling system interface components helps. Go to Settings → Applications → All applications, find System Interface (or System UI), click three dots in the corner and select Remove Updates. This will return the component to the factory version, which often solves software glitches.
To sum up, it is possible to completely disable autolock on Xiaomi, but requires a combination of methods: Standard means can achieve 10 minutes of work, the developer mode gives infinite time when charging, and third-party applications allow you to flexibly manage this process in any conditions.
💡
The best way is to use the developer mode “Do not turn off the screen” in conjunction with Power Bank for stationary use, or the application-blocker for mobile scenarios.
