The alarm clock on Xiaomi smartphones is one of the most sought-after tools, but its setting often raises questions for new users.Unlike the iPhone or "pure" Android, firmware is a big part of the system. MIUI It offers advanced features: repeatable signals, smooth volume increase, integration with Google Assistant and even location alarms, while the Clock interface is regularly updated, and instructions for older versions are available. MIUI (12th) is no longer relevant.
In this guide, we will look at all the ways to set an alarm on Xiaomi, Redmi and POCO, from basic settings to hidden chips like smart awakening (when a smartphone analyzes sleep phases). Separately, we will focus on the typical mistakes: why the alarm does not work in Do Not Disturb mode, how to change the default melody and what to do if the signal is too quiet. All instructions are relevant for MIUI 14/15 (2026) and tested on Xiaomi 13/14, Redmi Note 12 and POCO F5 models.
1. Basic method: through the standard app "Clock"
The easiest method is to use the built-in Watch (dial icon) app, which is preinstalled on all Xiaomi smartphones and does not require a download from Google Play. The interface may vary slightly depending on the version of MIUI, but the algorithm remains the same.
To add a new alarm clock:
- Open the Watch → app → go to the Alarm tab (bell icon at the bottom of the screen).
- Press the + (plus) button in the lower right corner.
- Set the time with the dial or enter the numbers manually.
- Select the days of the week to repeat (by default - a single signal).
- Click Save (check in the upper right corner).
Important: MIUI 15 has a feature called "Smooth Awakening" - the alarm starts to sound quiet 30 seconds before the set time and gradually increases the volume. To activate it, after saving the alarm, tap it → Signal settings → turn on the Smooth Awakening switch.

2. Quick setup via notification panel
If you need to set your alarm as quickly as possible without opening the Watch app, use the notification bar.This method works on all Xiaomi smartphones with MIUI 12 and later:
Swipe down from the top edge of the screen to open the notification bar → find the alarm label (plus bell icon). If there is no shortcut, tap the pencil icon (Edit) and add it manually.
After clicking on the shortcut, a quick setup window will open:
- 🕒 Choose time with sliders (hours/minutes).
- 🔄 Specify repetition (once, daily, on weekdays, etc.).
- 🔔 Choose a tune from the suggested (or leave it by default).
- ✅ Press Ready – The alarm is activated automatically.
This method is convenient for one-time alarm clocks, but is not suitable for fine-tuning (for example, choosing a smooth awakening or a delayed signal).

3. Voice activation of the alarm clock (Google Assistant / Alice)
Xiaomi smartphones support voice alarms via Google Assistant (for global firmware) or Alice (for Russian versions of MIUI), which is especially convenient when hands are busy or the screen is locked.
For Google Assistant:
- Activate the assistant with your voice (OK, Google) or hold the Home button.
- Say, “Set the alarm for 7:30” or “Wake me up tomorrow at 6:00 a.m..”
- The assistant will suggest confirming the time and days of repetition, say yes or adjust the settings.
For Alice (on Russian firmware):
- 🎤 Say, Alice, set the alarm for 8:00».
- 🔄 For a repeating signal, specify: “Every weekday at 7:15 am».
- ⚠️ Alice will create an alarm clock in the Yandex app, not in a standard Watch. → Alarm clocks.
💡
If the voice assistant does not recognize the command, check the language settings in Settings → Additional → Language and Input → Voice input. For Google Assistant, select Russian (Russia), for Alice - Russian without regional options.
4. setting additional alarm clock parameters
The standard alarm clock in MIUI allows you to flexibly adjust the signal to your needs. Once you set the alarm clock, tap it on the list to open advanced options:
| Parameter | Description | Recommendations |
|---|---|---|
| Repeat | Selecting the days of the week for automatic operation | For working days it is convenient to choose a PN-Pt, for weekends - SB, SS |
| Melody. | Sound signal (standard or custom tunes) | Choose tunes with smooth volume increase (e.g. Morning Flower) |
| Put it down | Delay time when pressing the "Delay" button | Optimal: 5-10 minutes. Too short a delay prevents a full awakening |
| Vibration. | Additional vibrational alert | Turn on if you sleep with headphones or in a noisy place |
| Marking. | Text description (e.g., “charge for an electric vehicle”) | It helps to distinguish alarm clocks if there are several of them. |
A critical feature of MIUI 14/15: If you use Do Not Disturb (DND) mode, the default alarm clocks do not work. To fix this, go to Settings → Sound and Vibration → Do Not Disturb → Alarms and turn on the Allow Alarm Switch.
