Nighttime behind the screen of the Xiaomi Mi smartphone can be a real test for the eyes – even minimal brightness sometimes seems dazzling in the dark. The problem is compounded by the fact that standard MIUI settings do not always offer flexible options for adjusting backlights. In this article, we will discuss all possible ways to reduce the brightness of the screen below the standard minimum, including hidden system functions, third-party applications and even hardware solutions for especially sensitive users.
It is important to understand that Xiaomi uses different types of screens (AMOLED, IPS LCD) In their devices, and the methods of adjusting the brightness may differ. AMOLED-display function available DC-And this is a dimming that changes the way you think about lighting in the dark, but on budget models like the Redmi Note 10, you're going to have to scratch your head over workarounds. MIUI Before rooting and changing system files.
If you're looking for ways to not just reduce brightness, but make it comfortable for the eyes without losing detail, focus on the night mode with color temperature calibration and adaptive backlight with light sensor, which are often ignored, although they can radically improve the perception of the screen at night.
1. Standard brightness settings in MIUI
To start with, the basic method that works on all Xiaomi Mi smartphones without installing any additional apps. MIUI provides two ways to adjust the brightness: through the slider in the notification curtain and through the settings menu. However, both options have a limitation - the minimum brightness is often too high for comfortable use in complete darkness.
To reduce the brightness in a standard way:
- Turn the notification curtain swipe from top to bottom.
- Find the Brightness slider (usually located to the right of the battery icon).
- Move the slider to the left until it is full – this will set the minimum possible brightness for your model.
If this is not enough, try turning off automatic adjustment:
- 📱 Go to Settings. → Display.
- 🔄 Turn off Adaptive Brightness (or Auto Brightness in older versions) MIUI).
- 🌙 Turn on Night Mode and set up the schedule or activate it manually.
⚠️ Note: Some Xiaomi models (e.g. Mi) 9T Pro) the minimum brightness in the notification curtain is locked at the level 20-30%. To circumvent this limitation, alternative methods from the following sections will have to be used.
Night mode and blue light filter
The MIUI night mode feature not only reduces brightness, but also changes the color temperature of the screen, reducing the amount of blue light that prevents you from falling asleep. This technique is especially useful if you use a smartphone before bed. Unlike simple brightness adjustment, the night mode can be finely adjusted to your preferences.
How to activate and configure night mode:
- Open the Settings → Display → Night mode.
- Activate the switch at the top of the screen.
- Adjust the Color Temperature – a value of 2400K to 3000K is recommended for maximum comfort.
- Set a schedule (for example, from 22:00 to 7:00) or turn on the mode manually.
For more flexible settings:
- 🌓 Enable Adaptive Temperature (if available) – it will automatically adjust the hue depending on the time of day.
- 🔍 Check for Night Mode Brightness (on some firmware it is hidden in additional settings).
- 📱 In the models with AMOLED-screens (e.g. Mi 11) enable Dark Theme in combination with Night Mode for dual effect.
| Parameter | Recommended value | The effect |
|---|---|---|
| Color temperature | 2400K–3000K | Maximum reduction of blue light |
| Brightness in night mode | 10–20% | Additional reduction of illumination |
| Schedule | 22:00–7:00 | Automatic on/off |
| Adaptive temperature | Included. | Smooth day/night transition |
💡
If the night mode seems too yellow, try setting the temperature at a level that is not too high. 3500K — It will reduce eye strain but retain more natural colors.
3. Hidden developer settings for fine adjustment
MIUI hides a number of useful options in the developer menu, including the ability to manually calibrate the minimum brightness.This method requires activation of the developer mode, but does not require root rights. Note: on some models (Mi 10T, POCO X3) these settings may be missing or not work correctly.
How to enable and use hidden settings:
- Activate Developer Mode: Settings → About Phone → MIUI Version (click 7 times in a row)
- Back to Settings → Additionally. → For developers.
- Find the option Minimum Brightness (or Adaptive Brightness → Minimum Value).
- Set the value in the range of 1-10% (depending on the model).
Additional useful options in the developer menu:
- 🔧 Turn off automatic brightness – completely blocks adaptive backlighting.
- 🌗 Simulation of color space – allows you to select an sRGB profile for softer colors.
- 🔄 Window animation → No animation – reduces the load on the processor at low brightness.
⚠️ Note: On some devices (Redmi) 9A, Mi 9 Lite) changing the minimum brightness through the developer menu can cause the screen to flicker. If this happens, reset the settings to standard or use alternative methods.

4. Applications for ultra-low brightness
If standard methods don't work well, third-party applications will come to the rescue, and they can reduce the brightness below the system minimum by applying a translucent filter or direct control of the backlight, and we tested several solutions and selected the most reliable ones.
Top.-3 dimming-in:
- Night Shift (free, no root): 🌙 Reduces brightness to 1% by filtering. 🔄 Automatic turn-on on schedule. 📱 It works on all Xiaomi models, including POCO redmi.
- Dimly (paid version, no root): 🎯 Accurate brightness adjustment with step 1%. 🔧 Support for gestures for quick management. 🛡️ No special permits required.

What you need to know DC-dimming:
- ✅ Pros: no flickering, more comfortable perception at low brightness.
- ❌ Cons: can slightly distort colors at very low brightness levels, increases power consumption by 5-10%.
