What is different from the dark theme on Xiaomi

Many users mistakenly refer to the dark theme as “night mode,” but these are two different tools with different tasks:

🌙 Blue light filter (night mode) – reduces the amount of blue spectrum in the backlight of the screen, making the image warmer (yellow orange) This reduces the strain on the eyes and helps the body prepare for sleep.
🖤 Dark theme – changes the color scheme of the interface MIUI It doesn't affect the light spectrum, but it reduces the brightness of the screen as a whole, which is also good for the eyes.

The ideal way to use it in the evening is to turn on both modes simultaneously: a blue light filter will soften the backlight, and a dark theme will reduce the contrast of the interface. AMOLED-screens where black completely turns off pixels, reducing power consumption.

📊 What mode do you use in the evening?

Only a blue light filter.

Only a dark topic.

Both regimes together.

Method 1: Quickly enable through the notification panel

The easiest way to activate night mode is to use the Quick Settings Panel, which works on all Xiaomi smartphones regardless of the version. MIUI:

Swipe your finger down from the top of the screen to open the notification bar.
If the panel is displayed in a shortened form, swipe down again to open it completely.
Find the "Night Mode" button (crescent icon) 🌙) or "Blue light filter".
Tap the button once to turn on mode. Re-pressing it will turn it off.

If the button is not in the main panel, click on the icon "⚙️ Edit” (or "✏️"), Find Night Mode on the list and drag it to the active area, MIUI for POCO) The button may be called "Eye Comfort".

Add the "Night Mode" button to the visible area|

Check that the mode is turned on / off with one tap|

Make sure the shortcut is not hidden behind the swipe down|

Set up the transparency of the panel (in) MIUI 15) for convenience-->

Note that you only turn on the blue light filter through the notification panel, and to activate the dark theme, you need to go to the settings (more on this below) or use the Xiao voice assistant. AI (If it is supported by your model).

If you need to not only turn on the night mode, but also adjust its intensity or set up automatic turn on, do the following:

Open the Settings app (cog icon) ⚙️).
Go to the Screen section (or Display in global firmware).
Select "Blue Light Filter" (or "Eye Comfort"/"Night Light").
Activate the slider at the top of the screen to turn on the mode.
Use the Intensity slider to adjust the filtering level (recommended range: 40–70%).

In the same menu you can configure automatic inclusion:

🕒 "Schedule" - select a fixed time (for example, from 22:00 to 7:00).
🌅 "Dusk to Dawn mode will be activated automatically based on your location (access to geodata required).

In the models with MIUI 15 (e.g. Xiaomi) 13T Or the Redmi Note 13 Pro.+) In this menu appeared the option "Adaptive filter" - it automatically adjusts the intensity depending on the lighting in the room (works through the light sensor).

💡

If you turn on the blue light filter, you reduce the intensity to 30 to 40 percent and give your eyes 5 to 10 minutes to adjust, and after a while, your brain will get used to it, and colors will come naturally.

Method 3: Including a dark theme (addition to night mode)

The dark theme doesn't replace the blue light filter, but it complements it perfectly.

Go to "Settings" → Display".
Select "Dark Mode" (or "Dark Mode").
Activate the slider at the top of the screen.
In the "Schedule" section, set up automatic turn on (by time or sunset / dawn).

Nana MIUI 14/15 There are additional options:

🎨 "Color scheme" - the choice of shade of a dark theme (black, dark gray or "AMOLED Black for maximum charge savings).
🔄 "Follow system settings" - synchronization with the blue light filter settings.
📱 "Forced for all applications – enabling dark interfaces even in programs that don’t support them (may work unstable).

If after turning on a dark theme, some applications (for example, Instagram or TikTok) remain light, check their settings - many social networks have their own dark mode switch, independent of the system.

Why does dark theme not work in some apps?

Not all developers adapt their software to the system dark theme of Android, VK Telegram has its own external settings that are not synchronized with the MIUI. In such cases, you need to manually enable dark mode inside the application itself.

Method 4: Voice control (for models with Xiao) AI)

If your Xiaomi smartphone supports voice assistant Xiao AI (available on most models for the Chinese market and some global versions, you can control the night mode voice:

Activate Xiao. AI, Holding the home button or saying, Hey, Xiao. AI" (if the function is on).
Say one of the commands: "Enable night mode" (activates the blue light filter), "Enable dark theme", "Switch off the blue light filter".

On global firmware, the voice assistant may not understand these commands in Russian, so try English versions:

Turn on night mode


Enable dark theme




Disable blue light filter

Voice control is convenient when you are taking up your hands (e.g. cooking or lying in bed), but recognition only works when you are connected to the Internet — without Xiao. AI They won’t be able to process your team.

Method 5: Configure through the "Sleep" and "Do Not Disturb" modes

V MIUI 14/15 And we have a feature called "Sleep Modes," which can automatically turn on the night mode at a given time:

Turn on the Blue Light Filter option and Dark Theme option if necessary.

This mode may also include:

📵 Turn off all notifications (except alarm clocks),
🌙 Dim the screen to minimum brightness,
