How to increase the brightness of the screen on Xiaomi: all the ways from standard to hidden

Xiaomi's smartphone screen is dim, and standard brightness settings aren't saving you? You're not alone, this is a problem faced by owners of devices from Redmi Note 10 to flagship Xiaomi 14 Ultra. The reasons can be several: from a banal software failure to hardware limitations laid down by the manufacturer. In this article, we will discuss all possible methods of increasing brightness, including little-known tricks with MIUI, engineering menus and even hardware solutions for older models.

It's important to understand that screen brightness on Xiaomi is not just controlled by a slider in the notification curtain, but it uses adaptive lighting, light sensors and energy-saving algorithms that can artificially limit the maximum level. AMOLED-displays (for example, Xiaomi 13 Pro) brightness automatically decreases when displaying dark colors to save battery. IPS-The matrices can be protected against overheating.

Before you start settings, check the obvious: is there a protective film on the screen (it can create a “turbidity effect”), is not on reading mode (Settings → Display → Reading Mode) and is not activated the function Dark theme, which visually “muts” the interface. If all is well, read on.

1. Standard brightness settings in MIUI

Let’s start with the basic method, which works on all Xiaomi, Redmi and POCO models regardless of the MIUI version. Even if you consider yourself an advanced user, check these parameters – sometimes the problem lies in the small things.

Open the Settings → Display and pay attention to the following points:

• 🔄 Adaptive brightness: Turn off this switch if you want to manually control the backlight. MIUI Often understates the brightness in rooms with artificial lighting.
• 🌞 Maximum brightness manually: move the slider to the right end. In some firmware (for example, MIUI 14) maximum value hidden - pull the slider beyond the scale.
• 🌙 Night mode: make sure it's turned off or set to minimize dimming. The "warm" filter on visually dims the screen.
• 📱 Screen resolution: in models with FHD+ (for example, POCO F5) Check if the permit is not approved HD+ — It reduces clarity and subjective brightness.

If the screen still seems dim after this manipulation, move on to the next section, especially for older models (e.g. the Redmi Note 8 Pro), where maximum brightness is limited by hardware.

2. Hidden brightness settings in MIUI (for advanced)

MIUI hides a few settings that can be changed without root permissions, which are not officially dokumented, but work on most devices with MIUI 12-14 firmware.

The first way is to activate the extended display mode:

1. Open the Settings. → The phone.
2. Click 5-7 times on the MIUI version until the notification “You are a developer” appears.
3. Return to the main settings menu and select Additional → For developers.
4. Find the USB Debugging option and turn it on (this will unlock hidden options).
5. Now in Settings → Display may appear a new item Advanced screen settings (on some models it is called Color mode).

You'll find this menu:

• 🎨 Contrast: Increase the value to the maximum – this will visually “lighten” the image.
• 🔍 Gamma correction: try setting a 2.0 or 2.2 value for a more juicy display.
• ☀️ Color temperature: cold tones (6500K+) They are subjectively perceived as more vivid.

The second way is to use the test menu (not work on all models):

##36446337##

Enter this code in the Phone app as a number. If the menu opens, you'll see Brightness and Max Brightness. Set maximum values in both (e.g. 255). Be careful: the wrong settings can lead to a flickering screen!

💡

If after changes to the engineering menu, the screen started to flicker, reset to factory settings via Settings → System → Reset settings (select "Reset network and display settings").

3. Problems with the illumination sensor and their solution

One of the most common sources of brightness problems is that the light sensor is not working properly, and it's located next to the front camera, and it's responsible for automatically adjusting the backlight, and if the sensor is contaminated or damaged, the system may mistakenly "think" you're in a dark room, and force the brightness to decline.

How to check and correct:

1. Clean the sensor: wipe the area around the front chamber with an alcohol napkin, and dust and greasy prints block the light.
2. Calibrate the sensor: Go to Settings → Display → Adaptive Brightness → Calibration. Follow the instructions on the screen, placing the phone in different lighting conditions.

Check the sensor's operation.

If the sensor is damaged, it can be turned off completely:

• In Settings → Special features → Physical buttons, find the Automatic Brightness Adjustment and turn it off.
• Or use it. ADB-PC: Adb shell settings put system screen_brightness_mode 0 This command forcibly translates the brightness adjustment into manual mode.

4. Energy saving modes and their effect on brightness

MIUI aggressively optimizes power consumption, and often at the expense of screen brightness. Even if you haven't manually turned on the saving mode, the system can activate it automatically when the battery is low or the CPU is high.

Where to look for restrictions:

Pay special attention to thermal throttling. If your Xiaomi gets hot (for example, during games or charging), the system forcibly reduces the brightness to reduce the load on the processor. Check the temperature using the CPU Monitor app. If the phone regularly heats up above 45 ° C, try:

• 🧊 Clean the case of dust (especially important for models with active cooling, such as Black Shark).
• 🔋 Charge the phone when it is off or using the original adapter.
• 🎮 Disable high-performance mode in games (Settings) → Special facilities → Turbo-playing mode).

💡

If the brightness drops during games or watching videos, the problem is 90% due to overheating, so the solution is to use a cooling case or reduce the load on the GPU in the graphics settings.

5 Hardware Limitations: What to Do When the Maximum Is 50%

Some Xiaomi models (especially low-end ones like the Redmi 9A or POCO C31) have hardware-based maximum brightness limits, which are designed to save battery life and reduce the cost of the device. In such cases, no software method can reach the flagship level.

Method 1: Replacement of the display module

In service centers, you can install a screen from another model with higher brightness, for example, for the Redmi Note 10, a display from the Redmi Note 10 Pro will suit you (the difference in brightness is up to 200 nits), the cost of replacing it is from 2500 ₽, But consider the risks:

• ⚠️ Possible problems with color calibration.
• ⚠️ The phone guarantee will be lost.
• ⚠️ Not all services are taken for such operations.

Method 2: Use of external lighting

If you want high brightness for specific tasks (like shooting sunshine videos), consider:

• 📱 Lenses with backlighting (for example, Xiaomi Mi) LED Light).
• 💡 External USB-LEDs connected to powerbank.
• ☀️ Anti-glare glass (improves visibility in bright sun).

Method 3: Alternative firmware

Some custom firmware (such as LineageOS or Pixel Experience) can bypass hardware limitations, but this requires unlocking the bootloader and can lead to:

• Lose the warranty.
• Sensor malfunction.
• Problems with security updates.

Backup data | Check firmware compatibility with model | Unlock bootloader | Install TWRP Recovery | Download firmware from official source-->

6.Problems after MIUI update: how to get brightness back

Many users complain that after the MIUI update (especially on MIUI 13→14), the brightness of the screen has become lower.

• 🔄 Changes in adaptive lighting algorithms.
• 🔋 New energy-saving profiles.
• 📉 Restrictions for old models (manufacturer artificially "brakes" them).

How to get back to the old brightness:

1. Reverse to previous MIUI: Download the archive with the desired firmware from en.miui.com. Go to Settings → About Phone → System Update → Three Points → Select the service pack. Select the downloaded file and confirm the rollback.

Resetting display settings

Settings → System → Reset settings → Reset display settings

This will return the factory parameters of brightness, contrast and color profile.

Manual editing of the configuration file

• Install a file manager with root access (such as Root Explorer).
• Go to /system/vendor/display.
• Find the file. display_config.xml And change the parameter. max_brightness by the appropriate value (e.g, 4095 instead 2047).

If the brightness "floats" after the update (spontaneously changes), try:

Settings → Display → Adaptive Brightness → Resetting Learning

This option will reset the MIUI algorithms responsible for automatic adjustment.

7.Brightness comparison in different Xiaomi models

If you are planning to buy a new smartphone and the brightness of the screen is critical for you, pay attention to the specifications. In the table below, the maximum brightness data for popular models (measured in threads, cd/m²):

Note that peak brightness (e.g., 3,000 nits on Xiaomi 14 Ultra) is only achieved when viewed. HDR-In normal conditions (web surfing, messengers) the standard brightness (1000-1200 nits) is used).

If you need a smartphone with a really bright screen, pay attention to:

• 📺 Type of matrix: AMOLED usually brighter IPS (But not always, like the iPhone. IPS brightness up to 1600 nits).
• ☀️ Support HDR10+: These screens automatically increase brightness for compatible content.
• 🔋 The function "Automatic brightness 2.0" (is in the MIUI 14), which is better adapted to lighting.

💡

For outdoor use, choose models with a brightness of 800 nits. Anything below 500 nits will be poorly visible in direct sunlight.
