Modern. OLED-The screens that are equipped with flagship and many mid-budget Xiaomi smartphones require a special approach to managing pixel illumination. The use of a dark interface allows not only to reduce the load on the eyes in low light conditions, but also to significantly extend the battery life of the device. LCD-The lights where the lights are constantly burning, OLED Each pixel glows on its own, so black means a complete shutdown of the point, which saves energy.
Xiaomi has introduced native dark mode support into its MIUI shell and the new HyperOS a few years ago, but the functionality is constantly being improved, so users can not just switch the theme, but also adjust its behavior on a schedule, adapt contrast and even force dark mode activation in applications that do not officially support this feature, which makes the interface more flexible and personalized to the needs of the owner.
In this article, we will discuss in detail all the available ways to activate the “night” mode, hidden developer settings and methods of combating white elements in third-party programs. You will learn how to optimize the visual perception of information and save battery power using built-in system tools without the need to obtain superuser rights.
Native activation of dark theme in system settings
The easiest and safest way to switch the interface to the dark side is to use the built-in operating system tools. This method is guaranteed to work on all current versions of firmware from the manufacturer, ensuring stability and no conflicts with system processes. To start, you will need to open the main settings menu of your device.
Depending on the version of the shell, the path to the desired switch may vary slightly, but the logic remains the same. In the latest versions of HyperOS, developers have brought theme management to a separate block, making it more accessible. If you use the older MIUI 12 or MIUI 13, look for the corresponding item in the additional settings or personalization section.
Once the system switch is activated, the changes take effect instantly, with menus, notification curtains, standard apps like Calls, Messages and Gallery all changing their backgrounds to a deep gray or black color, which reduces the overall brightness of the interface, making smartphone use more comfortable in the evening.
To activate the mode, perform the following actions:
- 🌑 Open the Settings app on the main screen or in the curtain.
- 🌑 Find and navigate to the Topics section (in some versions it is called Wallpaper and personalization).
- 🌑 Select Dark Theme or Dark Mode and activate the slider.
- 🌑 If necessary, set the schedule of inclusion in the subitem Setup.
It is worth noting that the system theme only affects applications that are designed with support for dark mode. Many popular social networks and instant messengers automatically adjust to the system settings, but some programs can remain light, requiring a separate setup inside themselves.
Automatic schedule setting and adaptation to the environment
Manually switching the theme every time the time of day changes can be uncomfortable and forgetting to turn on the mode before bed. Xiaomi’s Android system, in conjunction with the shell, offers clever algorithms that take this task on themselves. You can set up automatic turn on the dark theme at sunrise and sunset or at a given time interval.
The environment adaptation feature is particularly useful for users who often travel or work in different time zones.The smartphone will determine the geographical location and local time by turning on a gentle screen mode exactly when it is really necessary for eye health.
To fine-tune, go to the theme management menu and click on the gear icon or Setup next to the theme switch. There are two main scenarios available: turn on by timer (for example, from 22:00 to 07:00) or by sunset and dawn time. The second option is preferable, since it changes dynamically throughout the year.
It is important to consider that automatic switching may not work if the system has turned off geolocation or set flight mode without prior time synchronization.
⚠️ Note: When using Sunset Time, make sure that the Settings or Themes app has permission to access the geoposition. Without this, the system will not be able to determine the exact time of light change in your region.
Forced activation in applications through developer mode
Often, the system theme is turned on, but the specific application continues to shine with a white flashlight, which is because the software developers have not added support for dark colors to their code, and you can solve this problem using the hidden developer menu, which is in every Xiaomi.
Activating this feature allows the system to force invert colors or impose a dark background where it is not provided, but it is worth understanding that this is a “crutch”: interface elements may look incorrect, buttons may become unreadable, and in some cases the application may work unstable.
To access hidden settings, you must first activate the developer mode. Go to Settings → About Phone and quickly click 7 times on the MIUI Version or OS Version. After a message about a successful activation, go back to the main settings menu, open Additional and find the Developers item.
Inside the developer menu, scroll down to Hardware Rendering Acceleration, find the option to Override Force-Dark and activate it, and immediately after that, all apps that support at least the basic dark theme should change their appearance.
What to do if the interface becomes unreadable?
Use of third-party themes and the Mi Themes store
The official Mi Themes theme store is a powerful customization tool that is often underrated. In addition to simply changing icons and wallpapers, you can find full-fledged themes that globally change the design of the system, making it completely black, even in places where the standard dark theme leaves gray shades.
Many design themes include not only graphic elements, but also modified styles of system applications: calculator, calendar, conductor and even settings menu. OLED-screens that cannot be done by standard means.
To find the right design, use a search for keywords: Black, Dark, AMOLED. The rating filter will help you choose high-quality works that do not contain layout errors. After downloading the theme, remember to apply it and restart the device to correctly display all elements.
Popular directions of design:
- ⚫ Pure Black: Topics with a completely black background (#000000) for maximum energy savings.
- ⚫ Minimal Dark: strict black and gray tones without unnecessary decorations.
- ⚫ Neon Dark: dark background with bright accent colors for buttons and icons.
Keep in mind that some themes may be paid or require you to view ads to activate, and third-party themes may include banner ads in the control center that you can get rid of by turning off recommendations in the theme settings.
☑️ Quality check of the topic
Comparison of dimming methods: Standard, Developer, Topics
The choice of dimming method depends on your priorities: stability, appearance or maximum battery economy. Each of the methods examined has its own technical features and affects the operation of the operating system in different ways.
The standard theme provides the best compatibility, but doesn't produce the perfect black color in all applications.Developer mode is a versatile "crutches" that can break layout. Third-party themes provide the best visuals, but require you to download additional resources.
| Parameter | Standard theme | Developer mode | A third-party theme (Mi Themes) |
|---|---|---|---|
| Stability | Tall. | Medium (possible bugs) | Depends on the author. |
| The depth of black | Grey/Dark Grey | Inverted | Perfect Black (OLED) |
| Impact on the battery | Moderate. | Minimum | Maximum (on OLED) |
| Difficulty setting up | Low. | Medium | Low. |
| Coverage of applications | Only system-based and optimized | All applications | System + selected |
For everyday use, most users are advised to combine a standard dark theme with a schedule setting, which provides a balance between comfort and functionality without the risk of a broken interface.
💡
The best choice for OLED-screens - installation of specialized AMOLED-themes from the Mi Themes store, as it provides the true black color of the pixels, completely turning off their glow.
Problem Solving: White background in curtain and settings
Users often encounter a situation where the theme is enabled, but the top curtain of notifications or the settings menu remains white.This is a common problem associated with caching graphic elements or conflicting versions of system components.
Try to reboot your smartphone first. Often, SystemUI's system process doesn't have time to load new styles after first turning on. If the reboot didn't work, check for updates to system components through the GetApps app or the built-in updater of themes.
Another reason could be the activated Simplified Mode feature or specific feature settings that take precedence over the topic. Turn off high contrast text or color inversion in Advanced Settings → Special features.
If the problem is only stored in one particular application, try clearing its cache. Go to Settings → Apps → All apps, find the problem app, select Memory and click Clear Cache. This won't delete your data, but will reset temporary interface files.
⚠️ Note: Do not use third-party inverter apps that overlay a color filter on top of the entire screen, which heavily load the processor, increase power consumption and make the image unnatural, unlike a native dark theme.
The Effects of Dark Theme on Eye Health and Battery
Moving to a dark interface isn’t just a matter of aesthetics, but research shows that using darker tones in low-light conditions reduces melatonin production, which promotes faster sleep after using the gadget.
Technically, on screens like AMOLED and Super AMOLED, which are equipped with the Redmi Note, Xiaomi Mi and Xiaomi’s flagship 13/14 models, every black pixel is physically turned off, which means that with 50% of the black elements in the interface, the energy consumption of the screen can be reduced by 30-40%.
However, on IPS-screens, which are found in the budget segment, there will be no energy savings, since the backlight there is constantly lit throughout the matrix area.
Regular use of a dark theme also reduces the risk of digital eye strain, known as Computer Vision Syndrome.The contrast between a bright screen and a dark room is the main enemy of vision, and black theme effectively eliminates this imbalance.
💡
For maximum eye protection, combine a black theme with a Read Mode (paper text) function, which adds a light yellowish hue and reduces the intensity of the blue spectrum of radiation.
