Setting the screen-off time on Xiaomi Redmi: a complete guide with hidden features

The screen of the Xiaomi Redmi smartphone is one of the main “eaters” of battery power, and the correct setting of the time to automatically turn it off can significantly extend the operation of the device without recharging. But not all users know that MIUI has several ways to control this parameter, from standard settings to little-known features like Advanced Sleep Mode or Scheduling. In this article, we will analyze all available methods for models from Redmi 9 to Redmi 13 Pro, including bypassing system constraints and solving typical problems.

It's important to understand that screen time is not just about battery life, but also about usability. For example, a timer that's too short will make you unlock your phone constantly when reading long articles, and a time that's too long will cut battery life by 15-20%. We tested all of the methods below on MIUI 12.5-14 firmware and found the best settings for different scenarios, from battery savings to maximum comfort.

Standard screen sleep time settings through the settings menu

The most obvious way is to use the built-in MIUI options.This method works on all Xiaomi Redmi models, including the budget Redmi A series and the flagship Redmi K. To change the timer, follow the following steps:

1. Open the Settings app (the gear icon on the home screen).
2. Go to the Screen section (or Display in some firmware versions).
3. Select the screen sleep option (may be called a sleep timer or auto-turn off the screen).
4. Set the desired time from the proposed options: from 15 seconds to 30 minutes.

On most devices, the following time intervals are available:

Important nuance: Some models (e.g. Redmi Note 11 Pro) will have an additional Adaptive Mode switch after the time is selected, and if activated, the system will automatically adjust the timer depending on your habits, for example, if you often leave the screen on for 2 minutes, the smartphone will eventually offer this default interval.

⚠️ Attention: On devices with AMOLED-screens (e.g. Redmi) K50 Or the Redmi Note 12 Pro.+) Too short a sleep timer can lead to accelerated degradation of the matrix due to frequent on/off of pixels.

Advanced settings through the developer mode

If standard options are not enough, you can activate hidden options through the developer mode, this will allow you to set custom sleep time (for example, 45 seconds or 3 minutes) or turn off the timer completely.

Turn on the phone in the settings|7 times press the version MIUI|Return to the main settings menu|Find a new section for developers-->

After activating the developer mode:

1. Go to Settings. → For developers.
2. Scroll down to the Screen block.
3. Find the Sleep option when connecting to charging – here you can set a separate time for cases when the phone is charging.
4. For a custom timer, use the screen wait time option (may be called screen timeout).

Hidden feature: Some versions of MIUI 13/14 have an undocumented Smart Sleep option that analyzes user activity, for example, if you watch a YouTube video, the screen will not go out even if the timer has expired, to turn it on:

Settings → Special features → Smart assistant → Smart screen sleep

⚠️ Attention: Custom time settings through developer mode may reset after update MIUI. We recommend fixing the selected parameters with a screenshot or a notebook entry.

💡

If the screen goes out too quickly after setting up, check out apps like Greenify or Battery Saver – they can force the display to turn off to save power.

Time-to-Schedule (for MIUI 12.5 and later)

Starting with MIUI 12.5, Xiaomi Redmi introduced a screen sleep schedule feature that allows you to automatically change the timer depending on the time of day, which is useful if you need a quick shutdown in the daytime to save battery, and in the evening – a longer one for comfortable reading.

To set up the schedule:

1. Open Settings → Screen → Screen Sleep → Schedule.
2. Activate the switch to Use the schedule.
3. Add a rule, pointing out: 🕒 Start time (e.g. 20:00) 🕒 End time (e.g. 23:00) ⏱️ Sleep timer (for example, 5 minutes)

Save the changes.

You can create several rules for different time intervals, for example:

• 🌅 Morning (7:00–10:00): 30 seconds (battery savings)
• 🌇 Evening (18:00–22:00): 2 minutes (comfortable reading)
• 🌙 Night (22:00–7:00): 15 seconds (preventing accidental pressing)

Using third-party applications for flexible customization

If you don't have the built-in options, you can use third-party utilities, which allow you to:

• ⏳ Set any time of sleep (e.g., 47 seconds)
• 🔄 Attach the timer to geolocation (for example, at home – 5 minutes, at work – 30 seconds)
• 📱 Manage settings through widgets or gestures

The best applications for Xiaomi Redmi:

Important: When using third-party applications, MIUI may display a special permission warning. To make the utilities work properly, give them permission to change the system settings:

Settings → Applications → Rights Management → Changes in system settings

⚠️ Note: Some applications (such as Tasker) require ROOT-You can use the rights to work fully on Xiaomi Redmi, and without them, some of the features may be limited. ROOT Deprives warranties and increases the risk of hacking the device.

Problem Solving: The screen goes off too quickly or doesn't turn off

If the screen sleep time is not working properly, the reasons may be as follows:

1.The screen goes out before the set time

• 🔋 Check the energy saving modes (Settings) → Battery → In mode, the ultraeconomic system forcibly reduces the timer to 15 seconds.
• 📱 Remove or update apps that may conflict with settings (e.g, DU Battery Saver, Avast Cleanup).
• 🔄 Reset the Screen settings to factory settings (Settings) → Screen. → Resetting settings).

2.The screen doesn't turn off at all

• 🕳️ Check the proximity sensor – if it is contaminated, the system may “think” the phone is pinned to the ear (relevant for Redmi 10 and older).
• 📲 Turn off the function of lifting to wake up (Settings) → Screen. → Rise to wake up – she can knock down the timer.
• 🛠️ Update the firmware: in MIUI 13.0.4–13.0.6 was an error that left the screen on when using Google Assistant.

💡

If the problem persists after all manipulations, reset to factory settings (Settings → About Phone → Reset).Be sure to back up the data before doing so!

Optimal settings for different use cases

The timing of your screen sleep depends on your tasks, and we tested different combinations on the Redmi Note 12 Pro and Redmi 10C and made recommendations:

Professional advice: On devices with AMOLED-screens (e.g. Redmi) K60) Put black wallpaper on and turn on Dark Theme, which will reduce power consumption by 10 to 15 percent, allowing you to increase screen sleep time without compromising your autonomy.

Hidden MIUI Features: How to Get Around System Limitations

MIUI imposes a number of restrictions on setting the screen's sleep time, such as not setting a timer longer than 30 minutes through a standard menu.

1.Use of ADB-team

With Android Debug Bridge (ADB), you can set any timer value, even if it doesn't appear in the interface.

1. Install ADB on your computer (you can download from the official website).
2. Connect Redmi to your PC and activate Debugging over USB (Settings → About Phone → MIUI Version → 7 times Press → For Developers → Debugging over USB).
3. Open the command line in the ADB folder and type:

adb shell settings put system screen_off_timeout 300000

Where 300,000 is millisecond time (in the example, 5 minutes). For 10 minutes, use 600,000.

2. Set up via Tasker (without ROOT)

If ADB seems complicated, use Tasker:

1. Create a new task (Task).
2. Add the Display action → Display Timeout.
3. Specify the desired time in seconds (e.g. 120 for 2 minutes).
4. Set up the trigger (for example, by time or when you start a particular application).
