How to increase the brightness of the screen on the Xiaomi Redmi phone

Xiaomi Redmi smartphones are known for their excellent value for money, but even the best models have situations where standard settings are not enough, sometimes the screen does not seem bright enough in bright sunlight or, conversely, blinds your eyes in the dark, the problem can lie in both banal energy saving settings and deeper system constraints.

In this article, we’ll take a closer look at all the available techniques to help you get the most out of your display. We’ll look at standard sliders, hidden engineering menus, and even software solutions if the hardware buttons stop responding. Proper calibration will not only improve the visual experience, but can also extend the battery life of the device.

Before we go to radical measures, it is worth understanding the nature of dim images. Often users accidentally activate the energy saving mode or the Read function, which significantly reduces the intensity of the pixels' glow. Sometimes the problem lies in the light sensor, which incorrectly reads the external conditions.

Basic setting through the notification curtain

The most obvious and quickest way to adjust is to use a quick access panel, which is always on hand in a MIUI or HyperOS shell, and to start, unlock the device and swipe from top to bottom to open the control center.

Find a slider with a sun icon. By moving it to the right, you increase the level of the matrix illumination. But what many people don't know is that just touching the slider doesn't give you maximum accuracy. If you want fine-tuning, click on the brightness icon itself, and the slider expands to allow you to set the value to within a percentage.

⚠️ Attention: Automatic adjustment may conflict with manual settings. If you set the maximum manually, but the screen still dims, check if the light sensor is on.

In some cases, the system can force the brightness to decrease when the processor overheats, a protective mechanism that cannot be turned off by standard means without risking damage to the hardware of the smartphone.

Autobrightness and sensor management

The automatic adjustment feature is designed to save battery power and protect your eyes, but Xiaomi's algorithms don't always work perfectly. The light sensor is often located at the top of the screen or in the speaker's frame. Pollution, protective glass or cases can block light from accessing the sensor.

To set autobrightness correctly, go to Settings → Screen → Brightness Level. You can activate or disable Automode here. If you prefer manual control, it is better to turn this option off completely, since the system will periodically “twist” values, ignoring your preferences.

There's also an adaptive brightness feature that learns from your habits, and if you're constantly spinning the slider to the maximum under certain conditions, remember that action. After a few cycles, the MIUI algorithm has to adapt and raise the backlight level on its own in a similar situation.

• 🌞 Regularly wipe the top face of the smartphone to the sensor works correctly.
• 📉 Turn off the power saving mode if the screen is too dim.
• 👁️ Use Reading mode only when necessary, it will yellow the screen.

💡

If the light sensor is glued with a low-quality protective glass, the brightness may jump. Try removing the glass and checking the sensor.

Hidden possibilities of the engineering menu

For advanced users who lack standard settings, there is an access to the engineering menu, which is a hidden part of the system that is designed to test the hardware, and you can check the performance of each component, including the following: LCD-display.

You can log in to the menu using the standard Phone app, you need to enter a special code. Most Redmi and Poco models have a combination of ##6484##. Once you enter, you will open a list of tests.

Inside the test mode, you can see the maximum capabilities of your matrix, but be careful: changing some parameters here can lead to incorrect display of colors or unstable interface operation, the engineering menu is designed for diagnosis, not for everyday reconfiguration.

If the code doesn’t work, your firmware version may be restricting access to these features, and you can try third-party apps from Google Play that emulate access to gamma and contrast system settings.

Solving problems with a dim screen in the sun

One of the most common complaints of Xiaomi owners is that the screen is poorly readable in direct sunlight, which is due to the fact that the maximum brightness of many AMOLED and IPS arrays in the budget segment is limited to 400-500 nits. On a sunny day, a minimum of 700-800 nits is required for comfortable use.

There's a software trick that allows you to temporarily raise the brightness above the standard maximum, which is to activate the "Increased Luminance" mode in the display settings if your model supports it, and it also helps to turn off the dark theme, since black on AMOLED screens means the pixel is off, which reduces the overall illumination.

⚠️ Warning: Prolonged use of the screen at maximum brightness in hot weather can lead to overheating of the battery and accelerated burnout of the matrix.

If the screen becomes dim in the navigator or when you start a video, check the settings of a particular application. Many programs have their own brightness switches that overlap the system settings.

Comparison of display and color reproduction modes

Brightness is not just about the amount of light, it's also about the perception of color. Xiaomi's screen settings have a Color Scheme section. Choosing the wrong profile can create the illusion of a dim screen. For example, "Paper" or "Classic" modes are often less saturated and perceived as paler.

For maximum visual effect, it is recommended to choose the “Saturated” or “Standard” modes, in which gamma correction is adjusted so that the image appears more contrasting and bright, even if the physical power of the backlight does not change.

Below is a table comparing the main features of the screen modes in MIUI/HyperOS:

Switching between modes is instantaneous. Experiment with settings throughout the day to see which profile works best for your eyes and lighting conditions.

💡

Choosing the right color profile can visually improve the brightness of the screen by 15-20% without changing the backlight settings.
