Crescent on Xiaomi phone: the value of the icon, how to remove and configure the mode โ€œDo not disturbโ€

Introduction: Why did Xiaomi have a crescent?

Have you noticed on your Xiaomi, Redmi or POCO a mysterious crescent icon in the top notification bar?This icon is one of the most frequent sources of questions among smartphone owners of the brand. It appears suddenly, often for no apparent reason, and can be both delightful (if you deliberately activate the quiet mode) and annoying (when it turned on on itself).

In fact, the crescent is a visual designation for Do Not Disturb (DND) mode, which blocks sound and vibration alerts. In MIUI, this mode has several levels of customization, and its activation can be either manually or automatically by schedule or rules. In this article, we will discuss all the possible causes of the icon, how to turn it off and fine-tuning the mode, which many people do not know about.

Itโ€™s especially important to understand the nuances of how DND works on Xiaomi, as the latest versions of MIUI 14/15 have changed its logic, for example, now the mode can be activated not only through the settings menu, but also through Quick Settings or even the voice assistant Google Assistant.

What does the crescent icon on Xiaomi mean: decoding the icon

The crescent icon in the Xiaomi status bar is a universal Do Not Disturb mode (DND) symbol that can be displayed in two variations:

  • ๐ŸŒ™ White Crescent on a blue/black background โ€“ complete blocking of all notifications and sounds (including alarm clocks, unless an exception is set up).

In MIUI, DND has 3 hidden intensity levels that are not always obvious to the user:

Level of regimeWhat's blockedDefault exceptions
QuietNotification and call soundsRepeated calls (if ringing 2 times within 3 minutes), alarm clocks
StrictAll sounds, including mediaAlarm clocks only (unless manually switched off)
Complete.All sounds and vibrations, including tactile feedbackNothing (even alarm clocks are off!)

Important: MIUI 15 Adaptive mode function appears DND, This feature automatically adjusts the lock level to your location (e.g., includes a strict mode in the theater or at a meeting from the calendar).+.

โš ๏ธ Note: If the crescent appeared on its own, check the Digital Well-Being settings in Google Services. Sometimes the mode is activated through the Sleep Time or Focus Mode function, which syncs with the calendar.

Reasons for Automatic Turning On of the โ€œDo Not Disturbโ€ Mode

If you didnโ€™t manually turn on the DND, but the crescent icon still appeared, the reasons may be as follows:

  • ๐Ÿ•’ Schedule in settings DND โ€” The mode can be activated over time (for example, from 23:00 to 7:00).
  • ๐Ÿ“… Calendar Events โ€“ if the meeting description contains keywords like โ€œmeetingโ€ or โ€œlectureยป, MIUI It can automatically turn on the quiet mode.
  • ๐Ÿš— Driving mode โ€“ when you connect to Android Auto or detect movement (through sensors), block notifications.
  • ๐Ÿ”‹ Saving charge - in the mode of ultra-savings (MIUI 14+) DND activated forcibly.
  • ๐Ÿค– Voice Assistant โ€“ Google Assistant or Xiao AI You can turn on voice command mode (e.g., โ€œOK Google, donโ€™t disturbยป).

To check what exactly triggered, go to Settings โ†’ Notifications and Status bar โ†’ Do not disturb โ†’ Auto-on rules. There will be a list of all active triggers with the ability to disable them.

๐Ÿ“Š How often do you spontaneously turn on the mode "Do not disturb"?

  1. Open Settings โ†’ System and device โ†’ Additional โ†’ Adaptive settings.
  2. Find the Adaptive Mode "Do Not Disturb" and deactivate the slider.
  3. Restart the device (sometimes changes are only applied after the reboot).

Hidden Do Not Disturb Mode Settings in MIUI

Few people know, but in MIUI, DND has advanced settings that allow you to fine-tune it, and here are the most useful ones:

  • ๐Ÿ”” Exceptions for repeated calls โ€“ you can set the interval (from 1 to 15 minutes), after which a repeated call from one number will break through the lock.
  • ๐Ÿ“ฑ Allowing notifications on the lock screen โ€“ even in mode DND You can display notifications without sound.
  • ๐ŸŽต Separate media and notification management โ€“ block notification sounds but leave music or video behind.
  • ๐Ÿ‘ค White contact list โ€“ calls and messages from selected numbers will take place even in strict mode.

To access these settings:

  1. Open Settings โ†’ Notifications โ†’ Do not disturb โ†’ Additional.
  2. Slip on the Exclusions and set up rules for calls, messages and apps.
  3. In the Sounds and Vibration section, you can turn off vibration when you touch or lock the screen.

An interesting life hack: if you need to temporarily turn off all sounds, but leave vibration for important notifications, select vibration only in the DND settings. This is useful in public places where sound is undesirable, but tactile signals will not disturb others.

If you often have to switch between DND modes, add the Do Not Disturb widget to the home screen. To do this, press the empty space on the screen โ†’ Widgets โ†’ find Do Not Disturb Mode and drag it to a convenient place.

DND issues on Xiaomi and their solutions

Sometimes, Do Not Disturb is not working properly: it spontaneously turns on, doesn't turn off, or blocks important notifications, and let's look at typical problems and ways to solve them.

Problem 1: The mode turns on on itself

Reason: The most common fault is the Digital Wellbeing or Adaptive DND settings.

Solution: Turn off adaptive features (see instructions above) and check the rules in Settings โ†’ Digital Well-being โ†’ Sleep Time.

Problem 2: Notifications donโ€™t come even after the DND is turned off

Reason: Maybe Flight Mode is turned on or synchronization settings are lost.

Solution: Go to Settings โ†’ Notifications โ†’ Additional โ†’ Resetting notification settings.

Problem 3: The crescent icon remains after the mode is turned off

Reason: MIUI interface glitch or shell conflict.

Solution: Reboot your device. If it doesn't work, clear the cache of the Android System application (Settings โ†’ Applications โ†’ Application Management โ†’ Three Dots โ†’ Show System โ†’ Android System โ†’ Clear the cache).

Alternatives to the โ€œDo Not Disturbโ€ mode on Xiaomi

If standard DND doesnโ€™t work for you, MIUI has alternative ways to manage notifications:

  • ๐Ÿ“ต In-plane mode** โ€“ completely shuts down communication, but leaves local functions (for example, alarm clocks).
  • ๐Ÿ”‡ *Silent mode* โ€“ only turns off sounds, but does not block notifications on the screen.
  • ๐Ÿ›ก๏ธ Private regime** (c) MIUI 15) โ€“ hides notifications from certain applications without completely blocking the sound.

  1. Swipe down to open the notification panel.
  2. Slip on the icon Sound mode (speaker with crossed bell).
  3. Choose the option: No sound, Vibration or Sound.

FAQ: Frequent questions about the crescent on Xiaomi
