The appearance of a small crescent in the status bar of your Xiaomi or Redmi smartphone is often puzzling for users, especially if this symbol appeared suddenly and blocks audio notifications. This visual indicator indicates that the device has activated Do Not Disturb mode. Unlike full silent mode, this feature is a smart tool that allows you to flexibly manage the flow of incoming calls and messages without turning off the phone completely.
Many gadget owners face a situation where the phone stops ringing at a certain time or when an incoming call, and a mysterious icon is burning in the corner of the screen. Understanding the function is critical to not miss a really important call from loved ones or colleagues, while remaining protected from intrusive information noise at other times.
In this guide, we will discuss in detail why the moon icon appears, how to customize it to your needs, and how to completely disable this feature if it bothers you. We will look at the differences in the interface between the different versions of the MIUI and HyperOS shells, so that the instruction is relevant for most models, from the budget Redmi Note to the flagship Xiaomi 13 and 14.
The main purpose of the mode is to "Do Not Disturb" The function behind the crescent symbol was developed by Android engineers and adapted by Xiaomi specialists to create a controlled digital space. The main purpose of this mode is not to completely ignore the outside world, but to selectively filter events. When the "Do Not Disturb" mode is activated, the smartphone by default blocks the sound signals, vibration and light indication for most applications and incoming calls. However, unlike simply turning off the sound, this mode allows you to create exceptions. You can set the system so that the phone is silent during the meeting, but at the same time the phone is activated by blocking the calls from the selected contacts, even if you are guaranteed to turn off the alarm. This makes the feature indispensable for people with irregular schedules or those who want to limit their phone use at night. 💡Use Do Not Disturb mode instead of turning the sound off completely if you're afraid of missing an emergency call from loved ones -- set their numbers to exceptions, and they can be heard even in silence. It's important to understand the difference between a normal silent mode and a do Not Disturb mode. In the first case, the phone just doesn't make any noise, but the screen can light up and the vibration when touched can remain active. In the second case, the system goes into a state of deep rest, ignoring the background notification processes, which also positively affects the battery's autonomy.
Users are often confused about the reasons for the moon icon, as it can be activated in two fundamentally different ways. The first option is manual activation through the control panel. In this case, the user activates the function himself, and it will work until he decides to turn it off. This approach is convenient for short-term situations: watching a movie in the theater, holding important negotiations or sleeping at an unusual time. The second option that raises the most questions is automatic activation on a schedule. In the system settings, the function “Planned”, which allows Xiaomi to set the time intervals after the system: 2300, for the transition to automatically, for example, when the system will be set at the time intervals: 07, for the time intervals. That's why the moon icon can appear on the screen at the same time, even if you haven't touched the sound settings. Why does the mode turn on? Often the cause is synchronization with sleep mode or activation of the "Bedtime" function in digital well-being, which duplicates the "Do Not Disturb" mode settings. The difference between these methods is the level of control. Manual mode gives you full power here and now, whereas the schedule requires pre-tuning, but eliminates the need to remember to turn on silence every night. Understanding which method is activated in your case is the key to controlling the moon.
The fastest way to remove the disturbing symbol and return the phone to make sounds is to use a notification curtain. MIUI It's suitable for a situation where the mode has been manually activated and needs to be deactivated urgently: 📱 Swipe from the top edge of the screen down to open the control center. 🌙 Find the icon with the image of the crescent (sometimes it can be hidden in the second page of the icons, you need to swipe to the left). 👆 Click on the active icon to turn grey or disappear, which means switching off mode. ☑️ Check the disable mode Open the notification curtain:Find the moon icon:Make sure it is not illuminated:Check the ringtone sound: 0 / 1 If after clicking on the icon in the curtain, the icon in the status bar does not disappear, this is a sure sign that the mode is activated automatically on a schedule or through a third-party application. In this case, simply pressing the button in the curtain may not give a long-term effect, and a deeper immersion in the system settings will be required.
To control the automatic activation of the Do Not Disturb mode, you need to go to system settings. The path may vary slightly depending on the firmware version, but the logic remains the same. You need to find the section that handles sounds and notifications. → Sound and vibration → Don't disturb me. MIUI This item might be called "Do Not Disturb" in the main settings menu. Inside this section, you're interested in "Planned" or "Schedule" option. Here you'll see a switch that's probably active. You can use it: 🔘 Completely disable the switchboard "Planned" to the phone stop turning on silence itself. ⏰ Change the time interval by setting a more convenient hours for night rest. 📅 Set up a repetition by selecting only certain days of the week if the regime is not needed every night. 💡Turning off the schedule in the settings is the only guaranteed solution if the moon icon appears on the Xiaomi phone at a certain time. Note that new versions of HyperOS may have a slightly modified interface, and schedule settings may be made to a separate Repeat or Add Rule submenu.Take a careful look at the options available so you don't turn off important system notifications like the alarm clock.

Sleep apps, habit trackers, or productivity programs (such as Forest, Sleep as Android) often have their own notification blocking features.
