How to turn on the alarm on Android Xiaomi: full instructions with secrets

The alarm clock on Xiaomi smartphones is not just a wake-up function, but a whole range of time management tools. From standard one-time signals to complex repetition schedules, the capabilities of MIUI devices go far beyond basic expectations. However, many users face difficulties: the alarm clock does not work when the screen is off, the sound is too quiet, the settings are reset after an update. This article will help you understand all the nuances from basic settings to solving non-obvious problems.

Xiaomi's peculiarity is that even in simple things like an alarm clock, the manufacturer adds unique chips. For example, integration with the Mi Home smart home allows you to run scenarios when the alarm goes off, and the Smart alarm function analyzes the sleep phases to wake up at the optimal time. But in order for all this to work, you need to properly configure not only the application itself, but also the system parameters of the phone. Next, a detailed analysis based on the latest versions of MIUI 14/15 and the features of popular models (Redmi Note 12, POCO X5, Xiaomi 13).

Standard method: Appendix "Clock"

The basic method of activating the alarm is through the regular Watch app, which is pre-installed on all Xiaomi devices. Its interface may vary slightly depending on the version of MIUI, but the general logic is maintained. On models with MIUI 14+, the application received an updated design and additional options, for example, selecting a tune from Spotify (with a connected account).

To add a new alarm clock:

1. Open the Clock app (icon with dial).
2. Go to the Alarming Signal tab (bell icon in the bottom menu).
3. Press the + button in the lower right corner.
4. Set a time, select the days of repetition (if necessary).
5. Press Save – the alarm is activated automatically.

An important nuance: some models (POCO F4, Redmi 10) require manual switching on to the right of the clock after setting the alarm clock, and if you don't, the signal won't work even if the time is set.

Alternative ways to set an alarm clock

If the standard Watch app doesn't work for some reason, there are a few alternative methods that you can use if you:

• 🔄 You need to set an alarm on your phone (via Google Assistant).
• 🎵 Requires a custom tune from the user files.
• ⏰ Sync alarms between devices (via Mi Cloud).
• 🤖 Automation is required (e.g., turning off the alarm clock when connecting to the Mi Band).

One of the most convenient options is a voice command via Google Assistant:

1. Activate the assistant with your voice (OK, Google) or hold the Home button.
2. Say, Set the alarm for 7:30 or wake me up tomorrow at 6:00 a.m.
3. The assistant will offer to save the alarm clock - confirm the action.

On models with MIUI 13 and below, voice alarms via Google Assistant may not work in power saving mode. To avoid this, add the Google app to the battery optimization exception list.

Setup of repeated alarm clocks and exceptions

The alarm clock function is useful for those who wake up on a single schedule on weekdays but want to get some sleep on weekends. In MIUI, this is implemented flexibly: you can adjust not only the standard days of the week, but also custom schedules (for example, "every Tuesday and Thursday").

To set up a repetition:

1. Create a new alarm clock or edit an existing one.
2. Click on the Repeat field (under time).
3. Choose the right days or set up a casting schedule.
4. For exceptions (e.g., "repeat on weekdays except Fridays"), use the "Exclude days" option.

On Xiaomi 12/13 models with MIUI 14, the Smart Repetition option has been introduced, which analyzes your habits and suggests optimal alarm days, but this feature only works when synchronization with Mi Account is enabled.

💡

If the alarm doesn’t work on the designated days, check the date and time settings in Settings → Additional → Date and Time. With the Auto-Detection option enabled, failures are unlikely, but if you manually changed time zones, the schedule may get lost.

Problems and Solutions: Why the Alarm Doesn't Work

The most common complaint of Xiaomi users is that the alarm doesn’t work at the appointed time. There may be several reasons, and most of them are related to battery optimization or energy saving settings.

• 🔋 Power saving mode: App Watch should be on the exception list.Way:Settings → Battery → Choice of applications → The clock → Choose Without Limitations.
• 🔔 Do Not Disturb: Even if the alarm is on, it won’t work if the mode is activated DND with the signal blocking. Exception: MIUI 14 alarm clocks are breaking DND, If the mode settings are not disabled, allow alarms.
• 🔕 Media volume: The alarm clock uses a separate sound stream. Check that the alarm clock slider is not at zero in the volume settings.
• 🔄 Reset after update: after major updates MIUI Sometimes alarm settings are reset. Always check them after you update the system.

Another common problem is that the alarm goes off, but the sound is too quiet, because Xiaomi defaults to limit the volume of signals through the speaker.

1. Open Settings → Sound.
2. Select the Loudness of the Alarm.
3. Pull the slider to maximum.
4. Activate the option to turn up the volume at the alarm clock (available on MIUI 13+).

Advanced features: smart alarm and integration with Mi Band

Xiaomi’s MIUI 14/15 smartphones support the Smart Alarm feature, which analyzes sleep phases through built-in sensors or Mi Band data. The system wakes the user up at light sleep 30 minutes before the set time, making waking up less stressful.

1. Open the alarm in the Watch app.
2. Click on three dots in the upper right corner → Smart alarm clock.
3. Turn on the switchboard and connect the Mi Band (if any).
4. Set a time range for a smart wake-up (±30 minutes by default).

For the full operation of the function requires:

• 📱 Smartphone on MIUI 14+ (on MIUI 13 works in limited ways).
• 💤 Mi Fitness sleep monitoring enabled (if Mi Band is used).
• 🔄 Synchronization of data with Mi Account.
• 📶 A stable internet connection (for cloud sleep analysis).

Important: A smart alarm consumes additional energy due to constant monitoring of sensors. On models with a small battery (Redmi 9, POCO M4), this can reduce battery life by 5-10%.

💡

The smart alarm clock is most accurate when used with the Mi Band 7 Pro or Xiaomi Smart Band 8 – their heart rate and movement sensors allow you to more accurately determine the phases of sleep.

Third-party applications: when standard functions are few

If Xiaomi's built-in capabilities don't suit, you can use third-party apps, which offer advanced functionality:

• 🎶 Custom melodies: downloading tracks from cloud services or local files.
• 📊 Sleep statistics: integration with Google Fit or Apple Health.
• 🔄 Automation: Turning off the alarm clock by geolocation (for example, when you leave the house).
• 🎯 Gamification: problems to wake up (e.g., solve a mathematical problem).

Top.-3 apps:

1. Sleep as Android: supports smart wake-up, integration with Mi Band and Google Assistant. There is a free version with limitations.
2. Alarmy: Hard alarm clocks with tasks (e.g. scanning) QR-It's good for those who sleep dead".
3. Timely: a minimalist design with cloud synchronization, perfect for multi-device users.

When using third-party alarms, remember to add them to the battery optimization exceptions, otherwise they may not work.Way: Settings → Battery → App selection → Select the app and install No Limits.

💡

If you use Sleep as Android with the Mi Band, turn off standard sleep monitoring in Mi Fitness to avoid sensor conflicts.

Energy Saving and Alarm: How to Combine

One of the major conflicts at Xiaomi is between battery life and alarm clock performance, and aggressive MIUI optimization often puts the background down, causing the signals to fail, to avoid this:

1. Turn off the adaptive battery: Settings → Battery → Battery settings → Adaptive battery Disable this option – it limits background activity.
2. Add "Clock" to Autostart: Settings → Applications → Application Management → Watches → Autostart Turn on the switchboard.
3. Set up Power Saving Mode: Settings → Battery → Energy Saving Mode → Select Balanced or Performance (but not Super Energy Saving).

On models with MIUI 15, the option Optimize for alarms in battery settings has been introduced, which automatically relaxes the limitations for wake-up applications.

1. Go to Settings → Battery → Battery settings.
2. Find the Optimization section for alarm clocks.
3. Include the switchboard and add the desired applications to the list.

Warning: These settings can reduce battery life by 10-15%, but ensure that the alarm goes off even when the battery is low.

💡

There's a bug on the POCO F5 and Redmi Note 12 Pro+ with MIUI 14: when Super Power Saving is on, the alarms go off, but without sound. The solution is to use Balanced Mode.
