The light screen on Xiaomi is not only a matter of comfort, but also a matter of vision safety, especially when used for long periods. Many users face the problem of too dark a display after updating MIUI, activating energy saving mode or accidentally changing settings. In this article, we will discuss all possible methods of brightening the screen, from basic brightness parameters to hidden color correction and calibration functions that work on models from Redmi Note 10 to Xiaomi 13 Ultra.
It's important to understand that a light screen is a combination of several parameters: brightness, color temperature, contrast, and even adaptive settings for lighting. We will not limit ourselves to the obvious advice of "move the brightness slider", but consider system tricks, including turning off Dark Mode, resetting graphics settings and working with the engineering menu for advanced users.
If your Xiaomi suddenly fades after a fall or moisture, it is already a matter of hardware failure (damage to the plume or matrix), and such cases require repair, here we focus exclusively on software solutions for serviceable devices.
1. Basic screen brightness setting
So, to start with the obvious, manual brightness control, which in MIUI, you can change in two ways:
- 📱 Through the notification panel: swipe down from top to bottom to open the curtain, and find the brightness slider (POCO F4, Xiaomi 12T) It's hidden under the "Brightness" button -- tap the sun icon.
- ⚙️ Through Settings: Go to Settings → Display. → Brightness. You can activate Auto Brightness here, but note that it often understates in dark rooms.
An important nuance: if the brightness slider is locked at a minimum level, check whether Reading (in the notification curtain) or Energy Saving (Settings → Battery) is turned on, these features force the brightness to decrease to 30-50%.
On devices with AMOLED-screens (Xiaomi 13 Pro, Redmi) K50 Pro) the minimum brightness may appear too low due to the specifics of the technology, in which case it will help to turn off the function Adaptive brightness or use of night light with reduced intensity.
2. Disabling dark theme and reading mode
A common cause of darkening is activated dark theme or Read mode, which changes not only the background of applications, but also system elements to bring back the light interface:
- Go to Settings → Display → Dark Theme and select Off or Follow the application settings (if you need to leave dark mode only in individual programs).
- In the same Display tab, find Read Mode and deactivate it. Some firmware has it called Vision Protection.
Hidden setting: MIUI 14 has a Contrast Text option (Settings → Special Options → Size and Style of Text) that can make text too pale. Turn it off if the text becomes poorly readable.
💡
If after disabling a dark theme, some apps (such as YouTube or Telegram) remain dark, go to their settings and manually switch the theme to "Light".
3. Calibration of colours and screen temperature
Sometimes the screen doesn't seem dim because of the brightness, but because of the wrong color temperature (predominance of cold or warm shades) or the downed color profile parameters. MIUI has built-in tools for correction:
- 🎨 Color temperature: Settings → Display. → Color temperature. Move the slider closer to the Cold hue, and it will visually brighten the picture.
- 🔍 Color profile: In the same section, select Saturated or Standard instead of Soft (the latter often makes the image fade).
On devices with AMOLED (Xiaomi 12S Ultra, POCO F5 Pro), an additional Color Mode setting (Settings → Display → Additional Display settings) is available. Select Live for maximum color brightness.
| Parameter | Recommended value for light screen | The effect |
|---|---|---|
| Color temperature | Cold (6500K-7000K) | Reduces yellowness, makes white color brighter |
| Color profile | Saturated | Increases contrast and juiciness of colors |
| Adaptive brightness | Off. | Prevents automatic dimming |
| Reading mode | Off. | Removes the gray filter |

Verification of energy saving regimes
MIUI aggressively optimizes power consumption, which often affects the brightness of the screen. Even if you haven't manually turned on the power saving mode, it can activate automatically when the battery is low (usually below 15%).
- Open the Settings. → Battery.
- Click on the gear icon (⚙️) In the upper right corner and select Power Saving Modes.
- Set Performance or Balanced instead of Energy Saving.
- Turn off the option to automatically switch mode.
Critical detail: on some models (Redmi 9A, POCO M3) in Super Power Saving mode, brightness is fixed at 10-20% and is not regulated.

5. Reset display settings and software update
If all previous methods failed, the problem may lie in the failure of system parameters, in which case, resetting the display settings or updating the firmware:
- 🔄 Reset: Settings → System system → Resetting settings → Reset the display settings, and that brings back brightness, color temperature, and adaptive settings to factory values.
- 📲 Update MIUI: Go to Settings. → The phone. → System updates. Sometimes brightness bugs are fixed in newer versions of firmware. MIUI 13.0.4 for Redmi Note 11 was fixed failure with adaptive brightness.
Warning: Before resetting your display settings, check if you are using custom color profiles (e.g., through apps like Screen Balance) and reset them.
⚠️ Note: If after the update MIUI screen has become dim and brightness slider is not working, try clearing the Settings app cache (Settings) → Annexes → Application management → Settings → Clear the cache. This often helps with interface glitches.
6. Advanced Methods: Engineering Menu and ADB
For experienced users willing to take a chance, there are ways to fine-tune the display through an engineering menu or ADB-These methods can be dangerous if used incorrectly, so we give them with reservations.
Method 1. Engineering menu (for qualified users only!):
- Open the Phone app and enter the code ##3644633##.
- Go to the Display or Screen section.
- Find Brightness, Contrast, or Gamma options and manually increase the values (write down the originals!).
Method 2. ADB-commands for resetting graphic parameters:
adb shell settings put system screen_brightness 200
adb shell settings put system screen_brightness_mode 0The first command sets the brightness to a maximum (value 200), the second - turns off the adaptive adjustment.
⚠️ Note: Incorrect settings in the engineering menu can cause damage to the matrix (for example, setting a Gamma value too high causes the backlight to overheat!
💡
If you are not sure about your actions, you should contact Xiaomi Service Center, some of the options of the engineering menu are blocked after unsuccessful changes, and they can only be restored through firmware.
