The situation when in the middle of the night or early morning suddenly starts to ring a smartphone, familiar to many owners of Xiaomi equipment, often users forget that they set a reminder a few days ago, or triggered a system alarm, which is difficult to find in the standard list. In the operating system MIUI The new HyperOS management of these features has its own features, different from pure Android.
You can turn off the interrupting sound in a number of ways, from simply turning off the switch in the app to completely removing the system component, and it is important to understand the difference between user timers and pre-installed system tasks, which can be activated automatically after a firmware update.
In this article, we will look at all possible scenarios, from the standard Clock app to hidden alarm clocks that often baffle inexperienced users, and learn how to manage schedules, customize exceptions, and completely eliminate unwanted audio signals.
Standard shutdown via the Watch app
The most obvious and common method is to use the regular Watch app, which is pre-installed on all Redmi and Poco smartphones, and this is where you keep your main reminder list, so you first need to unlock the device screen and find the dial icon, and if you don't have one on your desktop, open the menu of all the apps or search.
After you start the app, go to the alarm tab, which is usually located at the bottom of the screen or in the top menu, depending on the version of the shell. This will show a list of all active timers. Find the one that interferes, and click on the switch to the right of the time to deactivate it. The color of the indicator will change from orange or blue to gray, which signals a successful shutdown.
If you want to remove the alarm clock permanently, not just temporarily, you need to press the line itself with time to open the detailed settings. In the menu that opens, scroll down to the end and select the "Delete" option. The system will request confirmation of the action, after which the record will be erased from memory.
It's worth noting that newer versions of MIUI may have slightly different interfaces, with some users choosing to swipe the alarm to the left or right over a row with time on the general list, a gesture that doesn't work in all firmware versions, so the basic method through the delete menu remains the most versatile.
Managing Repeated Signals and Days of the Week
A common cause of a sudden call is a misconfigured repetition, so you could set an alarm for one particular day, but accidentally activate the Repeat function, and now the phone rings every day or on odd days of the week. To avoid this, carefully study the settings of each timer.
Go to edit a specific alarm clock and notice the line “Repeat.” If it lists days of the week (for example, “Pn, W, Sp...”), then the signal will sound regularly. For a one-time event, you need to select the option “Once” or manually deselect all days, leaving only the current date, if the interface allows.
- 📅 Checking the days: Make sure none of the days of the week are illuminated if you need a one-off signal.
- 🔔 Type of Repetition: Some versions have a choice of “Every Day”, “Worker” or “Individually».
- ⏰ Expiration date: Check if an alarm clock has been set with an end date in the distant future.
Special attention should be paid to the Smart Alarm feature, which can automatically turn on the signal if the system decides that you need to get up at this time based on your calendar appointment schedule.
⚠️ Warning: If you have turned off your alarm clock but it still rings, check if the second, hidden or duplicate alarm is on the list at the same time.
Third-party applications and conflicts
Many users install alternative alarm apps from Google Play, such as Alarmy or Sleep Cycle, which have more functionality. The problem is that they can run in the background and ignore the phone's standard settings (quiet mode), and if you can't find the sound source in the standard app, it's probably third-party software.
To identify the culprit, go to your smartphone settings through Settings → Apps → All Apps. In the list, find all the programs you have installed that are associated with time, sleep, or reminders. Go to the information about each and check if there are active notifications or services running.
If you find a suspicious app, try using the Settings menu or delete it completely. Often, these programs have their own task lists that don't show up in the clock's system widget. Also check the permissions: if the app is given the right to "Run Yourself" or "Bypass Do Not Disturb" mode, it will sound even when the media sound is turned off.
In some cases, two applications conflict: system and third-party. For example, you set an alarm in Google Watch, and a duplicate is created in MIUI Watch, and it is recommended to leave only one source of time to avoid confusion and unnecessary battery consumption.
System Alarms and MIUI Notifications
One of the most annoying features of the MIUI shell is the system notifications, which sound like an alarm clock, not classic timers, but low battery, charger connection, security event reminders or system updates, which cannot be simply turned off in the Watch app, as they refer to system sounds.
To turn off the charging sound, which is often confused with an alarm clock, you need to go to Settings → Sound and Vibration → Additional audio settings. Here you can find the Charging Sound switch and deactivate it, similar to the screen locking sounds and other system events.
☑️ Diagnostics of system sounds
Also worth a look at is the Security app, which is the system control center on Xiaomi, and inside it is the Optimizer or Reminders section, and sometimes users accidentally activate reminders about charging the battery (like “Charge when 20% is left”) or about cleaning the memory, which are performed by system services and sound quite loud.
| Signal type | Source | Where to turn off | Impact on the system |
|---|---|---|---|
| Alarm clock | Annex Clock | The alarm clock tab | No. |
| Timer. | Annex Clock | Timer tab | No. |
| Charging. | System / Security | Sound settings / Security | No. |
| Event | Calendar/Mi Account | Calendar Annex | No. |
Noteworthy reminders from Mi Account: If your device is synchronized calendar, events from the cloud may come in the form of audio signals. Check your sync settings in Settings → Mi Account → Sync and disable unnecessary items such as Notes or Recorder if they are not used.
Do Not Disturb and Sleep Schedule
Xiaomi’s Do Not Disturb feature has its own nuances: it doesn’t by default silence alarms installed in the system app. However, if you want your phone to be completely silent, including alarm clocks (except for emergency ones), you need to set exceptions.
Go to Settings → Sound and Vibration → Don’t disturb. You can set a schedule here, for example, from 23:00 to 07:00. In this mode, the phone will not make sounds when calling or texting. But it is important to check the “Exceptions” or “Allow sounds.” If there is a tick “Alarm clocks”, they will sound even in this mode.
Difference between Silence Modes
There's also a feature called "Sleep Mode" or "Sleep Time," which is integrated with Google Wellbeing or Xiaomi's own development, which can automatically turn on a dark theme, restrict app usage, and, importantly, change notification behavior, and check if it's on schedule and if there's a limit on alarm clocks.
If you need to be guaranteed to turn off all sounds for a certain time, it is better to use a physical volume slider (if there is one on the model) or a software slider, lowering all scales (media, bell, alarm clock, system) to zero before bedtime.
Radical methods: disabling the system component
In the rare cases where the alarm is part of a system process that cannot be removed by standard methods (e.g., an integrated alarm clock from the operator or a specific firmware version for a specific region), users resort to more radical measures.
You can try turning off the Watch app through your app settings. Go to Settings → Apps → All Apps → Watch. If the Disable or Delete button is active, you can deactivate the system component. However, this can cause time widgets and timers to fail.
A more advanced method is to use ADB (Android Debug Bridge) via a computer, which allows you to delete or freeze system applications without root permissions, and you need to enable USB debugging in the Developer Menu.
adb shell pm disable-user --user 0 com.android.deskclockThis command will turn off the standard Xiaomi alarm clock. To get everything back, use the command with the replacement of disable-user to enable. ADB-commands require accuracy: an error in the name of the package can lead to unstable operation of the system.
⚠️ Note: Disconnect system components through ADB It can disrupt other smartphone features, such as desktop widgets or voice assistants, and only use this method if you are confident in your actions and understand the risks.
