Why is the Redmi 8 alarm clock not working properly?
The Xiaomi Redmi 8, released in 2019, is still popular with users due to its balanced performance and reliable MIUI firmware. However, even in this device, the alarm function sometimes behaves unpredictable: it works at the wrong time, does not turn off after a shutdown or ignores the settings altogether, the reasons lie in both software failures and the features of the MIUI 10/11/12 interface, which runs Redmi 8.
Most often, problems arise due to:
- 🔄 Battery optimization conflict – the system forcibly closes background processes, including the alarm clock service.
- 📱 Errors in the Clock app after the update MIUI or reset.
- 🔔 Incorrect notifications when the alarm is triggered but not displayed on the lock screen.
- 🤖 Google Assistant Fails if the alarm was set through the voice assistant.
In this article, we will discuss all the ways to turn off the alarm clock on Redmi 8, from standard to hidden, and also explain how to fix typical errors. If you find that the alarm clock does not turn off after clicking on Cancel or it works at random time, here you will find a solution.
Method 1: Disconnection through the “Clock” application
The most obvious and reliable method is to use the standard Watch app, which is preinstalled on all Xiaomi smartphones. the interface may vary slightly depending on the version of MIUI, but the overall algorithm remains unchanged.
Step-by-step:
- Open the Watch app (an icon with a dial on the home screen or in the app menu).
- Go to the Alarming Signal tab (bell icon in the lower menu).
- Find an active alarm in the list, and it will be marked with a green switch.
- Tap the switch to turn off the alarm clock (it will turn grey).
- To completely remove the alarm clock, click on it and select Remove in the top corner.
If the alarm doesn’t appear on the list but keeps going, check:
- 🔍 Repeat tab – perhaps the alarm clock is hidden under another category.
- 🔔 Notifications section in the settings of the “Clock” application (path: Settings) → Annexes → The clock → Notifications).

Method 2: Quickly shut down via notification panel
When the alarm goes off, the quickest way to turn it off is to use the notification bar, which works even if the screen is locked, but requires unlocking to confirm the action.
How to do this:
- When the alarm is triggered, swipe your finger down from the top edge of the screen to open the notification panel.
- Find a notification that says Alarm clock: [time] and swipe it left or right (depending on the MIUI version).
- Click Disable or Delete (some firmware versions may require confirmation).
Important: If the alarm was set through a third-party app (like Google Clock or Sleep as Android), the notification may look different.
💡
If the alarm goes off but the notification doesn’t appear, try unlocking the screen and swiping your finger down twice – this will open a full notification panel where the signal may be hiding.
Method 3: Disconnect via Google Assistant (XiaoAI)
If you have a voice assistant set up (Google Assistant or Xiaomi’s XiaoAI), you can turn off the alarm with a voice command, which is convenient when the smartphone is out of reach or you are busy.
Commands to disable:
- 🎤 For Google Assistant: “OK Google, turn off the alarm clock” or “OK Google, delete all alarms».
- 🎤 For XiaoAI: “Xiao Ai, turn off the alarm” (only works on Chinese firmware or with XiaoAI package installed).
Please note:
- ⚠️ Voice commands only work when an active Internet connection (Wi-Fi or mobile data) is in place).
- ⚠️ If the alarm was set through another app, the assistant may not see it.

Problem Solving: The alarm clock doesn’t turn off or it just goes off on its own
Sometimes the alarm clock on Redmi 8 behaves unpredictable: it does not turn off after clicking on Cancel, it works at random time or it turns on itself after rebooting. Let's consider the typical causes and ways to eliminate them.
| Problem. | Possible cause | Decision |
|---|---|---|
| The alarm clock does not turn off after clicking on "Cancel" | Clock app malfunction or battery optimization conflict | 1. Force stop the Watch app (Settings → Apps → Watches → Stop). 2. Add the Watch to the battery optimization exception list (Settings → Battery → Battery Optimization → Watch → No Limits). |
| The alarm clock is triggered at random times. | Incorrect repetition settings or conflict with other alarm clocks | 1. Check all alarm clocks in the Clock app for duplicates. 2. Make sure all repeat alarm clocks are turned off (Clock → Alarm clock → [select alarm clock] → Repeat → Never). |
| The alarm clock is activated after rebooting. | Failure of the com.android.deskclock service (system alarm clock) | 1. Clear the Cache of the Watch app (Settings → Apps → Watch → Memory → Clear Cache). 2. If the problem persists, reset the App settings (Settings → Apps → Watch → Memory → Reset settings). |
If none of these methods worked, try upgrading to the latest version of MIUI or resetting the Watch app. In extreme cases, you may need to completely reset your smartphone to factory settings (don’t forget to back up your data!).
💡
Before resetting the Clock app settings, export your current alarm clocks: open the Clock → Alarm clock → ⋮ (menu) → Exporting alarm clocks, which will allow them to be quickly restored after resetting.
How to prevent an accidental alarm clock?
To avoid future alarm problems, follow these guidelines:
⚠️ Note: If you use the "Do Not Disturb" mode (Settings) → Sound. → Don't disturb, alarm clocks may not work on time. Add the Clock app to the exception list or turn off the mode before bedtime.
Useful advice:
- 🔋 Check your battery optimization settings for the Watch app regularly». MIUI aggressively closes the background processes, which can lead to failures.
- 🔄 Update the firmware MIUI The Clock app to the latest version, and new updates often fix alarm clock errors.
- 📵 If your alarm is critical (like for morning wakes), duplicate it through Google Clock or a third-party app like Sleep as Android.
- 🔍 Check all active alarm clocks before bedtime — sometimes they are automatically created using functions like Reminders or Google Calendar».
If you often experience alarm clock problems, consider using a smartwatch or fitness bracelet (such as the Mi Band or Amazfit) that has its own alarm clocks that work independently of the smartphone and do not depend on optimizing the MIUI battery.
