How to make the screen brighter on the phone Xiaomi Redmi

Owners of Xiaomi and Redmi smartphones often face a situation where the standard maximum brightness of the display is not enough for comfortable use of the device in bright sunlight. This is especially true for models of the mid- and budget segment, where IPS-matrixes with a low margin of light flux are used.

You have to consider that automatic adjustment can work incorrectly due to the calibration of sensors or the glued protective glass. In this article, we will discuss all the available methods, from basic settings of the MIUI interface to the use of engineering menus and third-party applications. Correct contrast and color reproduction settings will also visually make the image more vivid and rich.

Before we start radical methods, it is worth checking the basic parameters, because sometimes the solution lies in simply turning off energy-saving functions. The system can artificially underestimate the performance to extend battery life. Next, we will look at each step in detail that will make the most of your display.

Basic brightness settings in MIUI

The first step is always to check the standard screen control interface, and in the MIUI shell and the new HyperOS, the light control is put in the notification curtain, and to access, you have to swipe from the top of the screen down, and there's a slider that controls the intensity of the backlight.

But simply moving the slider doesn't always work, and often you activate Auto Brightness, which takes control, and to make the screen as bright as possible by hand, you tap the icon with the letter "A" or the sun next to the slider to deactivate the automatic mode, and then the slider becomes available for manual control at 100%.

⚠️ Attention: When forced to turn on maximum brightness in the sun, the battery discharges much faster, and the device can significantly heat up.

Also worth noting is the Read or Vision Protection mode, which is often turned on by default during daytime, which adds a yellow filter and reduces the brightness of the blue spectrum, which visually makes the screen dimmer. → Screen. → Protection of vision.

💡

If the brightness slider doesn’t reach the end of the scale, try rebooting your smartphone – it will reset the backlight control drivers errors.

Management through Engineering Menu and CIT

To further customize the display parameters in Xiaomi smartphones, there is a CIT engineering menu. This is a hidden part of the system, designed to test hardware components, and is logged in through a set of special code in the Phone application. Enter the combination ##6484##.

In the list that opens, you'll find a item associated with the display, which can be called Display, LCD, or Screen, and in this section, you can often use extended calibration, and you can check the light sensor and manually set maximum lighting values that can be higher than the standard interface constraints.

• 🔍 Select a point «LCD» or "Display" in the test list.
• 🔍 Find the option “Backlight” or “Brightness Test».
• 🔍 Use sliders to set the maximum value (often 255 or 100%).
• 🔍 Click on Pass or Save to save the changes (if available).

It's important to understand that not all Redmi models allow you to save settings from the engineering menu, and in most cases, this tool is only for diagnostics, but checking here helps you to understand whether the screen is physically brighter than the standard system.

Disabling energy savings and adaptive functions

Aggressive energy saving policies are a common cause of dim screens. Android, in conjunction with MIUI, can reduce brightness when battery power is low or in the background for certain applications.

Go to Settings → Battery. Make sure Performance or Balanced mode is activated, but not Energy Saving. In Saving Mode, brightness is often limited to software, and the slider in the curtain may not go above 50-60%.

There's also a function called Adaptive Brightness, which learns from the user's habits, and if you've dimmed lights in the evening, the system can remember that, and not to maximize the brightness in the daytime, thinking you're more comfortable, and you can reset that data by turning off the autobrightness and setting the maximum value manually in bright light for a few minutes.

Use of the developer mode

The hidden settings for developers contain parameters that affect how the display works. To get there, you need to click on the build number 7 times in the Settings → About Phone section. Once you see the "You became a developer" sign, a new menu will open.

In the Settings section → Advanced settings → Developer (the path may differ in different versions) MIUI) You should look for points that are related to color gamut or saturation. Although there is no direct slider of brightness, changing the color gamut to "saturated" or "standard" can visually improve the perception of the picture.

Be careful when changing the settings in this section. Incorrect values can lead to incorrect display of colors or unstable interface, if you are not sure about the operation of a particular parameter, it is better not to touch it.

Third-party applications for enhancing illumination

If there's not enough system tools, Google Play apps come to the rescue, and they work by applying a white filter over an image or by forcefully changing values. PWM-Adjustment (if there are root rights) For ordinary users without root rights, applications that use overlays are available.

A popular solution is Brightness Slider, or analogues, which add their slider over the system, allowing you to "lighten" the image by software, and the effect is achieved by inverting colors or adding a layer of white with low transparency.

• 📱 Download a proven application (e.g., Super Brightness»).
• 📱 Give permission to display over other windows.
• 📱 Customize the gain level so you don’t “whitewash” the image completely.

⚠️ Note: Apps requiring root rights to directly control the lighting driver can cause the LEDs to fail when the currents are exceeded. Use them only if you are confident in your actions.

Remember, software-based brightness enhancement reduces contrast and can distort colors. Black can turn gray and lighter parts are lost. It's a compromise solution for reading text, but not for viewing photos.

Hardware limitations and calibration

It is important to distinguish between software failure and the physical limit of the matrix. Redmi budget models often feature screens with peak brightness of 400-450 nits, whereas flagship models can reach 800-1000 nits and above. No settings will make the budget screen brighter than its hardware allows.

Over time, the LEDs degrade. If your phone is several years old, a decrease in maximum brightness can be a sign of natural wear, and in such cases, software "twisting" the brightness will only accelerate the failure of the backlight.

If you notice that one part of the screen is brighter than the other or there are spots, this indicates uneven lighting or problems with the plume, in which case the software methods are powerless, and you need to replace the display module.

💡

The maximum brightness of the screen is a physical characteristic of the matrix that cannot be changed programmatically without loss of image quality or risk to hardware.
