Why Xiaomi Wallpaper is Darkening: Causes and Ways to Fix

Have you noticed that the wallpaper on your Xiaomi, Redmi or POCO smartphone has become dimmer, lost brightness or even darkened? This problem is more common than it seems, it affects users of various models, from the budget Redmi Note 10 to the flagship Xiaomi 14 Ultra. In some cases, darkening of the background image is a feature of the system, and in others it is a sign of serious problems.

In this article, we will discuss 7 main reasons why Xiaomi wallpapers can get darker, including hardware limitations, software errors and custom settings. You will learn how to diagnose a problem, which parameters to check first, and what to do if standard methods do not help.

Before you start settings, make sure that the problem is not temporary. For example, some wallpapers in the MIUI gallery automatically adjust to the time of day (it is brighter in the morning, darker in the evening).

1. Adaptive brightness and automatic screen adjustment

The most common reason for Xiaomi's wallpaper darkening is the adaptive brightness function, which in MIUI not only adjusts the screen's backlight to light, but can also automatically adjust the color profile of the wallpaper to reduce eye strain, especially when Read or Vision Protection is on.

How to check:

• 🔍 Open the Settings. → Display. → Brightness and turn off the slider Adaptive brightness.
• 🌓 Check if the Dark Theme is active or AMOLED-black (in some firmware it affects the display of wallpaper).
• 👁️ Turn on and off Vision Protection (in the same display settings) - if the wallpaper became brighter, the problem is in the color filter.

If the adaptive brightness turned off, the wallpaper returned to normal, it was an automatic correction, but it's not worth giving up completely, it extends the life of AMOLED-matrixes and reduces eye fatigue.

• 🎨 Try to set wallpaper with neutral tones (gray, beige) - they are less prone to distortion.
• ☀️ Manually calibrate the light sensor: in Settings → Display. → Adaptive brightness → Sizing.

⚠️ Note: On some models (e.g, POCO F4 Xiaomi 12T) Adaptive brightness can conflict with wallpaper downloaded from third-party sources. If after installing custom wallpapers they darkened, try downloading them through the standard Topics app.

2. Energy saving mode and productivity limitation

MIUI has several energy saving levels that can affect the display of wallpaper:

• 🔋 Balanced mode – slightly reduces the brightness of the background.
• 🔌 Super energy saving – limits color gamut and reduces contrast.
• ⚡ Ultra energy saving (available on some models) – transfers the screen to monochrome mode.

To check the impact of energy saving:

1. Go to Settings → Battery → Energy Saving Mode.
2. Choose High Performance or Balanced (but not Super).
3. Restart your phone and check the wallpaper.

If the problem is gone, it's the power saving mode that's to blame, but keeping your phone in high performance mode is not recommended, because it reduces battery life.

Disable super energy saving |Add the "Themes" app to optimisation exceptions |Install wallpaper through standard software (non-third-party launchers) | Check brightness after MIUI-->

On some firmware (e.g. MIUI 14 for Xiaomi 13), wallpaper may get darker due to a bug in MIUI Optimization optimization, in which case resetting the screen settings will help:

Settings → System → Reset settings → Reset display settings

3. firmware errors and MIUI bugs

The darkening of the wallpaper often occurs after the update MIUI Or custom firmware installations. MIUI 13 was a bug that caused the wallpaper to lose brightness when using live wallpapers. MIUI 14 A similar problem was observed on devices with AMOLED-The screens are activated by the Always-on Display function.

How to diagnose:

• 📱 Check the version. MIUI In Settings → If it's a recent update (released less than 2 weeks ago), it's probably a bug.
• 🔄 Try to roll back to the previous firmware version through Settings → Updating the system → Three points. → Select a Service Package.
• 🐛 Read the reviews on the forums (for example, 4PDA Xiaomi Community – If other users complain about the same problem, wait for a patch.

Interim decisions:

If the problem occurs after rooting or installing a custom recaveri (such as TWRP), try:

1. Fly the phone with a full Wipe (Wipe Dalvik, Cache, Data, System).
2. Install the official firmware through the Mi Flash Tool.
3. Check if the installed Magisk modules conflict with the system services.

⚠️ Attention: On devices with an unlocked bootloader, the darkening of the wallpaper may be due to improper operation of the display driver. In this case, only complete flashing with the bootloader locking back will help.

4. Hardware problems: matrix, plume, display controller

If the wallpaper darkens unevenly (for example, only in one part of the screen) or the problem is accompanied by other artifacts (bands, flickering, broken pixels), it is likely that the iron is to blame.

• 📺 Degradation AMOLED-Matrixes (typical for devices older than 2-3 years).
• 🔌 Damage to the display plume (for example, after falling or repairing).
• 🔧 Failure of the lighting controller (screens go out when heated).

How to check:

1. Set wallpapers with a uniform color (for example, pure white or red) If they show dark spots or a gradient, the matrix fails.
2. Light the flashlight on the screen at an angle - if in the off state you see traces of the image, it is burn-in (burnout AMOLED).
3. Check if the picture gets worse when the phone is heated (for example, after 10 minutes of play).

Decisions:

• 🔧 If the phone is warranty – contact the service center Xiaomi (matrix defect is usually covered by the warranty).
• 💰 If the warranty is over, the screen replacement will cost 30-70% of the cost of the device (depending on the model).
• 🔄 On certain devices (e.g, POCO X3 Pro) helps reconnect the display plume - but this is a temporary solution.

Nana AMOLED-screens (for example, in Xiaomi 11 Lite) NE or Redmi K40) Over time, the effect of burnout can manifest itself, when static interface elements (navigation panels, icons) are imprinted into the matrix, in which case the wallpaper will appear darker in areas where bright elements are often displayed.

5. Conflict with launchers and third-party themes

Many users install alternative launchers (Nova Launcher, Hyperion, Lawnchair) or custom themes from the MIUI Themes Store, sometimes resulting in conflict with system services, which causes the wallpaper to display incorrectly.

• 🎭 Themes with dark accents can put a filter on the wallpaper.
• 📱 Launchers can ignore brightness settings MIUI.
• 🔄 Some themes change the color profile of the screen, which affects the colors.

How to fix it:

1. Return the standard launcher: Settings → Applications → Default → Launcher.
2. Reset the theme to standard: Settings → Themes → My themes → Standard.
3. If you use Nova Launcher, check the Adaptive Icons and Wallpaper Style settings.

Some firmware (e.g. MIUI 12.5 Enhanced) may get darker due to a bug in com.miui.home.

Settings → Applications → Application Management → Show Everything → Home → Storage → Clear the Cache

If you use live wallpapers from Google Wallpapers or other sources, try:

• 🖼️ Install them through the standard Theme app (sometimes it better optimizes the display).
• 🔄 Reboot your phone after installing new wallpaper.

6. Effect of battery and temperature on screen brightness

On Xiaomi devices with smart battery management (such as the Redmi Note 12 or POCO X5), the system can automatically reduce the brightness of the screen when:

• 🔋 Low level of charge (less than 15%).
• 🌡️ Processor overheating (above 40-45)°C).
• ⚡ Use of a non-original charger.

How to check:

1. Connect the phone to charging – if the wallpaper became brighter, the problem is the battery restriction.
2. Check the temperature in Settings → Battery → Battery condition.
3. Try charging your phone with the original adapter (for example, 33 watts for Xiaomi 13).

Decisions:

• 🔌 Turn off Charging Optimization in Battery Settings.
• ☀️ Avoid overheating – do not use your phone in the sun or while charging.
• 🔋 If the battery is worn out (capacity less than 80%), replace it - the controller may not adjust the power of the screen correctly.

⚠️ Note: On some models (e.g, POCO F3 GT) When using the Game Turbo mode, the system forcibly reduces the background brightness to reduce the load on the background. GPU. Turn off this mode in Settings → Special facilities → Game turbo.

7. Resetting settings and extreme measures

If none of these methods worked, radical methods remain:

1. Reset display settings: Settings → System → Reset settings → Reset display settings This will return brightness, contrast and color profile to factory values.
2. Reset all settings (without deleting data): Settings → System → Settings Reset → Reset phone Settings Attention: This won’t delete files, but will reset all personal settings, including wallpaper.
3. Full Wipe: Log in Recovery + Volume Up → Wipe Data → Wipe All Data Use this method only if other methods have not worked.

If even after a complete reset, the wallpaper remains dark, there are two options:

• 🔄 Fastboot phone (instructions are available for you) 4PDA).
• 📱 Contacting the service center – perhaps the problem in the hardware.

💡

Before resetting, make sure to back up your data via Settings → System → Backup. This will save your photos, contacts and apps.
