How to make the screen bright on the Xiaomi phone: all the ways from basic to hidden

Why Xiaomi’s screen is getting dull and how to fix it

Have you noticed that your Xiaomi, Redmi or POCO display has lost its old juiciness? Colors have become faded, and in bright sunshine it is almost impossible to see anything on the screen? The problem of a dim screen is one of the most common among owners of Xiaomi smartphones, and there can be several reasons for it: from banal erratic settings to hardware limitations. In this article, we will examine all possible ways to increase brightness, from standard sliders on the menu to hidden MIUI functions and even hardware tricks.

It's important to understand that the brightness of the screen has a direct impact not only on the comfort of use, but also on the autonomy of the device. The brighter the display, the faster the battery goes down. AMOLED- and IPS-The panels in Xiaomi smartphones (such as the Xiaomi 13 Pro or Redmi Note 12) support adaptive lighting, which can automatically adjust to the lighting. If your phone doesn't, something has gone wrong. Next, you will learn how to return the screen to its former brightness without harming the eyes and battery.

Method 1: Manually adjust brightness through the notification panel

The most obvious and quickest method is to use a brightness slider in the notification panel, but many users miss important nuances:

• 📱 Swipe down from the top edge of the screen to open the notification bar.
• ☀️ Find the brightness slider (usually located at the top of the panel).
• 🔍 If there is no slider, click on the icon. ⚙️ («Settings») → Notification panel → Add the element “Brightness».
• ⚡ Move the slider to the right until the end – this will turn on the maximum brightness (usually up to 500-1000 nits depending on the model).

But there's a catch: even with the extreme right-hand position of the slider, the real brightness can be limited by adaptive settings or energy saving mode, and if you're still dim after this manipulation, move on to the next way.

⚠️ Note: On some models (e.g, POCO F5 or Redmi K60) when activating the “Reading” mode (Settings) → Display. → Read mode) the brightness automatically drops to 40-50%. Turn off this mode if it's on.

Method 2: Turning off automatic brightness and calibrating the light sensor

The adaptive brightness in MIUI often fails, as the screen becomes too dim in sunny weather, then blinds the eyes in a dark room.

1. Go to Settings → Display.
2. Find the Adaptive Brightness (or Automatic Adjustment) option and turn it off.
3. If you do not have an option, check the section Additional settings → Brightness.

If you need adaptive brightness, but it doesn’t work correctly, try recalibrating the light sensor:

• 🔦 Turn on adaptive brightness.
• 📱 Go to Settings. → The phone. → Version. MIUI and tap it 7 times to activate the developer mode.
• 🔧 Back to Settings → Additionally. → For developers and find the calibration of the light sensor.
• 🎯 Follow the instructions on the screen, pointing the phone at light sources of varying intensity.

In the models with AMOLED-screens (e.g. Xiaomi) 12T Pro or Redmi K50 Gaming) after calibration brightness can increase by 15-20% due to more accurate operation of the sensor.

💡

If the sensor doesn't work properly after calibration, try cleaning it from dust and dirt, and it's often the pollution that causes the readings to be incorrect.

Method 3: Using Hidden MIUI settings to increase brightness

MIUI has hidden parameters that allow you to exceed the standard brightness limit, which works on most models, including the Redmi Note 11, POCO X5 and Xiaomi 13 Lite:

1. Activate the developer mode (as described in the previous method).
2. Go to Settings → Additional → For developers.
3. Find the option to turn off automatic brightness (if any) and activate it.
4. Scroll down to the Hardware Rendering Acceleration section and turn on the Brightness Limit (or Force Full Brightness on English firmware).

After that, the maximum brightness of the screen can increase by 20-30%.

⚠️ Warning: Long-term use of the phone at extreme brightness (over 800 nits) can lead to accelerated degradation AMOLED-pixel burnout and increased battery consumption, it is recommended to use this mode only in bright sunlight.

Method 4: Color profile and contrast setting

Sometimes the screen doesn't seem dim because of the low brightness, but because of the wrong color settings. There are a few parameters in MIUI that can cloud the picture:

• 🎨 Go to Settings. → Display. → Color mode.
• 🔍 Choose Saturated or Standard (avoid Mild – it reduces contrast).
• 📊 Some models (such as Xiaomi 13) have Extended Color Mode available – turn it on for more juicy shades.
• 🌓 If the screen is still faded, check the color temperature setting – move the slider closer to Cold (this visually increases the brightness).

Nana AMOLED-The screens can also be turned on high contrast mode:

1. Hold your finger on the free space of the desktop.
2. Select Wallpaper Settings → Dark Theme → Additional.
3. Activate High Contrast (not available on all models)

This will not increase brightness in a literal sense, but will make the colors deeper and the text clearer.

Method 5: Virus testing and system optimization

If the brightness of the screen spontaneously decreases, it can be caused by viruses or background processes that limit performance.

• 🛡️ Install an antivirus (such as Dr.Web or Malwarebytes) and scan your device.
• 🔄 Go to Settings. → Annexes → Permits → Special permits → Optimizing the battery.
• 🔍 Find apps that can control brightness (like Lux Auto Brightness or Twilight) and turn off optimization for them.
• 🗑️ Clear the system cache: Settings → Memory. → Cleanup.

Also check if the phone has third-party launchers (like Nova Launcher or Apex) some of which have their own brightness settings that may conflict with system ones.

⚠️ Warning: If after cleaning the cache or removing the applications, the brightness returned to normal, but then fell again - the problem may be in the damaged firmware.

Method 6: Hardware causes of a dim screen and their elimination

If the software methods did not help, the problem may lie in the hardware:

• 🔋 Worn-out battery: with a low charge (less than 15%), many Xiaomi smartphones automatically reduce brightness. → Battery status.
• 💡 Damaged display plume: If the screen becomes dim after falling or repairing, the contact may have gone away.
• 🔄 The backlight controller fails: rarely, but it happens after updates. The solution is to roll back the firmware or replace the motherboard.
• ☀️ Factory marriage matrix: on some batches of Redmi Note 10 and POCO X3 Check the serial number on Xiaomi's website under warranty.

If you suspect a hardware malfunction, do a simple test:

1. Start Safe Mode (press the power button → “Safe Mode”).
2. Check the brightness of the screen -- if it's back to normal, the software is the problem. If it's not, it's the hardware.

Method 7: Alternative methods for advanced users

If the standard methods do not work, you can try advanced methods, but they require caution:

• 📱 ADB-commands to unlock hidden brightness settings: adb shell settings put system screen_brightness 255 adb shell settings put system screen_brightness_mode 0 (where 255 — maximum, 0 — light-out).
• 🔧 Editing the build.prop file (requires root): ro.lcd_min_brightness=10 ro.lcd_max_brightness=255 (Change the values to yours, but don’t exceed the limits for your model!).
• 🔄 Installation of a custom core (for example, FrancoKernel or ElementalX), which allows you to fine-tune the display settings.

These methods are only suitable for power users! wrong actions can result in a device bribing or warranty cancellation.

💡

Using ADB or root to change brightness can disrupt sensors and cause system instability.
