How to increase the brightness and screen time Xiaomi

Owners of Xiaomi, Redmi and POCO smartphones often face a situation where standard display settings are not enough, which may be due to bright sunlight, in which you can not see the content, or the desire to extend the battery life of the device. Understanding how to correctly manage the screen settings, allows you to significantly improve the user experience.

There are two main optimizations: increasing the visible brightness (to better see the picture) and increasing the screen burning time (to keep it from going out too quickly), both of which are critical for comfortable use of the Android shell MIUI or HyperOS.

In this article, we will take a look at all the available methods, from simple sliders in the notification curtain to hidden engineering menus, learn how to adjust adaptive brightness so that it works correctly, and learn how to prevent fast battery discharge due to too long a display burn.

Basic brightness setting through curtain and menu

The most obvious, but often ignored, way is manual adjustment, and many users get used to the averages, not realizing that in certain conditions, you can squeeze the maximum out of the matrix, and just swipe down to open the Control Panel.

At the top of the curtain is a sun slider, and by moving it to the right, you increase the intensity of the backlight. However, if you've brought the slider to the end and there's still not enough light, you should check the additional settings. Some models with AMOLED arrays have a hidden reserve of brightness that only activates under certain lighting conditions.

To access the full range of adjustment, go to the settings menu, where you can not only set a static value, but also calibrate the automatic mode, which often works out of the box incorrectly.

πŸ“Š How often do you change your screen settings?
Only in the bright sun.
I'm constantly experimenting.
Never change.
I'm only using auto mode.

It's important to understand the difference between software brightness and hardware brightness. Software adjustment can dim an image through software filters, whereas hardware changes the voltage on backlight diodes. It's the hardware component that's needed to maximize visibility in the sun.

Managing a sleep timer and locking the screen

The second aspect of the question of how to increase the screen clock concerns the time during which the display remains active without user action, and by default the system sets a timer for 30 or 60 seconds, which is not always convenient when reading books or browsing recipes.

To change this setting, you need to go to the system settings section, and here you will find the item responsible for the timeout or the "Sleep" of the screen, and choosing a higher value, for example, 2 or 5 minutes, will allow the device to stay active longer.

However, be careful. Increasing the time to "Do not turn off" or "30 minutes" can lead to a significant battery consumption, especially if you have Always On Display installed. OLED-In matrices, a static image at high brightness can cause pixels to burn out.

⚠️ Warning: It is not recommended to set maximum screen time if you often forget to put your phone in your pocket.This can lead to accidental taps (pocket set) and battery discharge.

There's also a screen retention feature that's available in some use cases, which allows the display to stay on while a particular application, like a navigator or a reader, is running, which is a smarter approach than changing the timer globally.

Calibration of the light sensor and auto-brightness

Automatic brightness is a feature that needs to adjust the backlight to the environment. Unfortunately, Xiaomi's algorithms don't always work perfectly. Often the phone is "lazy" to brighten up on a sunny day or glows like a spotlight in a dark room.

To fix this, you don't have to go straight to the engineering menu. First, try retraining the sensor. Turn on the Avtobrightness in the notification curtain. Then go out into a bright light (or turn on a bright lamp) and manually add brightness with a slider.

Then go back into the shadows and turn down the brightness manually, and the system will remember these two extremes for the current light level, and repeating the procedure several times under different conditions will make the MIUI algorithm work more predictably.

Hidden Calibration through ADB
For advanced users, there is the possibility of resetting the sensor calibration through ADB-commands, but this requires a PC connection and can disrupt the touch screen if misused.

If the software calibration doesn't help, maybe the problem lies in the protective film or case that covers the sensor. The light sensor is usually located at the top of the screen, next to the speaker, or built into the matrix itself under the screen.

Special reading opportunities and modes

MIUI and HyperOS have many features in their skin that directly affect the perception of brightness, and one of them is Read Mode, which changes the color temperature of the screen to make it warmer, which reduces eye strain, but visually it may seem that the screen has become dimmer.

By turning off this mode or setting up its schedule, you can return the screen to its original, cooler and brighter color gamut, and you should also pay attention to the β€œEye Safety” (DC Dimming) feature, which combats screen flickering at low brightness.

Turning on DC Dimming may slightly reduce maximum brightness for eye health, but on many modern models it is not noticeable. Check the settings in the Screen section to find a balance between comfort and visibility.

Engineering menu and hidden display settings

For those who want to have full control of the device, there is an engineering menu, a powerful tool that allows you to change the settings that are hidden from the average user, and be careful: incorrect changes can lead to incorrect display of colors.

To get into the menu, open the Phone app and enter the code ##6484##. This will trigger the CIT (Customer Interactive Test), and you can find display tests that allow you to check the performance of all pixels and set the maximum brightness forcibly.

In some firmware versions, you can turn off the brightness limit through this menu or through the developer menu (which is activated by seven times pressing "MIUI Version"). Look for items related to Minimum Brightness or Gamma calibration.

⚠️ Warning: Changing the parameters in the engineering menu without understanding their purpose can lead to incorrect touch screen or color reproduction!

Also on the developer menu is the β€œShow Touch” or β€œShow Point” option, which can be useful for diagnosis, but they do not increase brightness, but only add visual elements on top of the image.

The influence of the theme and wallpaper on the perception of brightness

The software component is important, because MIUI design themes can change the way you see brightness, and some themes have their own darkened menus that ignore the system brightness settings.

If you notice that after installing a new theme, the screen seems dimmer, try going back to the standard theme "Classic." Often, the system interface elements in third-party themes are not optimized for the same. HDR-content or high brightness.

In addition, the use of live wallpaper with a predominance of black color on AMOLED-Not only does screens save energy, but it also creates contrast that makes white interface elements appear brighter than they actually are.

πŸ’‘

Use static wallpaper with bright accents if you want the screen to appear lighter visually. Dark wallpaper is good for economy, but reduces the overall perception of lighting interface.

Check the settings of a particular theme, too. Some have separate brightness sliders for the settings menu and notification curtains that can be omitted by the user accidentally.

Frequently Asked Questions (FAQ)

Why does Xiaomi’s screen dim on its own in the bright sun?
It's a protective mechanism against overheating, and if the processor or battery gets hot, the system is forced to dim the brightness, even if the light sensor requires otherwise, and it could also be a sign that the autobrightness is not calibrated correctly.
How to increase the brightness of a flashlight on Xiaomi?
The flashlight brightness is usually software-adjusted. Go to flashlight settings (if available in your model) or use third-party apps from Google Play that allow you to control the LED current strength if this supports the device driver.
Is it harmful to keep maximum brightness constant?
Yes, it accelerates degradation. OLED-It is a matrix (burnout of blue subpixels) and discharges the battery much faster.
Can I increase the brightness above 100%?
There are amplifiers, but they act as a software filter, increasing contrast and saturation, rather than the actual strength of the backlight current, which often results in "digital noise" in the image.
Why did the MIUI update change its brightness?
Updates often include new display drivers or changed battery algorithms, which can reset your previous calibration settings, so you’ll have to re-learn the autobrightness training procedure.
