How to set an alarm on Xiaomi 8T: 3 proven ways

Xiaomi 8T is one of the most popular smartphones of the brand, but even experienced users sometimes have questions about basic functions, such as how to set the alarm clock correctly so that it goes off on time and does not fail at a critical time. In this article, we will discuss all possible ways to set the alarm on Xiaomi 8T, including hidden MIUI chips, which will help to avoid typical problems.

You'll learn how to set up the standard Watch app, what alternative programs to consider, and what to do if the alarm doesn't work, and also how to work in power saving mode and when the screen is off, all instructions are relevant to the latest versions of MIUI 14/15 and adapted to a specific model.

1. Standard way: The Watch app on Xiaomi 8T

The most obvious and reliable method is to use Xiaomi’s built-in Watch app, which is pre-installed on all MIUI devices and does not require additional downloads. The interface is intuitive, but there are a few nuances worth knowing about.

To set the alarm:

1. Open the Clock app** (the icon with the dial on the home screen or in the app menu).
2. Go to the Alarming Signal tab (bell icon at the bottom of the screen).
3. Press the + button in the lower right corner.
4. Set the time of operation by selecting hours and minutes on the dial.
5. Set up additional parameters: 🔔 Repeat – Select the days of the week (for example, weekdays only). 🎵 Sound – a melody or vibration (the default system signal is a sound). 🕐 Delay – the interval for the function “Repeat” (5 or 10 minutes). 📝 Title – Add a label (e.g., “Work” or “Workout»).

Ready.

Important: If you're using energy saving mode, your alarm may not work. To avoid this, add the Watch app to the exclusion list. Go to Settings → Battery and Performance → App selection and tick the Watch.

Alternative appendices for alarm clocks

If the standard solution doesn’t suit you (for example, due to a meager selection of tunes or lack of additional features), you can install third-party apps that offer advanced features: smooth awakening, morning tasks, integration with the weather, and even games for cheerfulness.

Top.-3 apps 8T:

• 🎶 Sleep as Android is a smart alarm clock with sleep analysis, CAPTCHA to wake up and integration with wearable devices.
• ☀️ AMdroid – flexible repetition settings, bedtime and wake-up tasks, and support for voice commands.
• 🔔 Timely – Minimalist design, cloud synchronization and the ability to set an alarm clock by geolocation (for example, when you get close to work).

To install any of these apps, go to Google Play Store, find it by name and click Install. Once installed, provide all the necessary permissions (access to the microphone for CAPTCHA, geolocation for Timely, etc.).

When using third-party alarms, be sure to add them to the battery optimization exceptions, otherwise they may not work in the background. You can do this in Settings → Applications → Application Management → [Select App] → Battery → No restrictions.

3.Setting the alarm clock through the voice assistant

If you're too lazy to dig through the menu, you can set the alarm with Google's voice assistant or Alice from Yandex, which is convenient when your hands are busy or you're already lying in bed.

Instructions for Google Assistant:

1. Activate the assistant with the voice command OK, Google or hold the Home button.
2. Say, set the alarm for 7:30.
3. The assistant will specify the parameters: Tomorrow? Every day?
4. Confirm the alarm clock.

The algorithm is similar for Yandex Alice, but the team says, Alice, set an alarm for 8 a.m. on weekdays. The main advantage of this method is speed.

• ❌ Not all tunes are available for voice selection.
• ❌ Do not disturb the assistant may not work.
• ❌ A stable connection to the Internet is required.

💡

If the voice assistant doesn't recognize the command, try to speak more clearly or reformulate a phrase. For example, instead of "set an alarm clock," say "set an alarm clock."

4.Why is the alarm clock on Xiaomi 8T not working?

One of the most common problems is that the alarm clock doesn't ring at the scheduled time, and there are several reasons, and most of them are related to energy saving settings or system constraints.

Another possible reason is the notifications disabled for the Watch app. To check this, go to Settings → Apps → App Management → Watches → Notifications and make sure all switches are active.

5. Alarm clock in the mode of the aircraft or with the phone turned off

Many users mistakenly think that the alarm clock will not work if the phone is turned off or switched to airplane mode. In fact, the mechanical alarm clock (built into the phone's chip) will continue to work, but with reservations:

• ✅ Works with the screen off (if the phone is on).
• ✅ It works in aircraft mode if the time is set manually.
• ❌ It does not work if the phone is completely off (power is off).
• ❌ It may not work if the battery is discharged to 0%.

If you need to be guaranteed to wake up even if your phone runs out, use an external alarm clock or a smartwatch (such as the Mi Band or Amazfit) that syncs with your smartphone and duplicates the signal.

💡

In airplane mode, the alarm will only work if the time on the phone is updated manually or synchronized with the network before activation.

6. Additional chips: smart alarm clocks and automation

Modern smartphones allow you to set up smart alarm clocks that adapt to your sleep or external conditions, for example, you can create a rule that the alarm clock rings only on weekdays or works 30 minutes before the rain (if you synchronize it with the weather service).

This is what I'd like:

• 🌦️ IFTTT — Automation service that connects the alarm clock to the weather, calendar, or other applications.
• 🔄 Tasker is an advanced tool for creating custom scripts (e.g. alarm clock) + Turning on the lights through Xiaomi Smart Home).
• 📅 Google Calendar – You can create a reminder event that duplicates the alarm clock.

Example of settings via IFTTT:

1. Install the IFTTT app from Google Play.
2. Create a new applet (If This Then That)
3. Select Weather Underground as the trigger (e.g., “If it’s expected to rain tomorrow”).
4. Please use Android Device → Set Alarm.
5. Set the time and save the applet.

These solutions take longer to set up, but pay off with convenience, like waking up to your favorite music from Spotify or getting a morning weather and news briefing.

Energy Saving and Alarm: How to Find Balance?

One of the main reasons why the alarm doesn't work is the aggressive battery optimization in MIUI.The system automatically shuts down background processes to save charge, but sometimes it interferes with critical functions.

To keep the alarm clock running smoothly:

1. Open Settings → Battery and Performance → Battery Consumption Management applications.
2. Find the “Clock” list and select “No Limits”.
3. For third-party alarm clocks (like Sleep as Android), repeat step 2.
4. Turn off the Adaptive Battery function in Settings → Battery → Additionally, if it interferes with the alarm clock.

Also check to see if deep sleep is activated (some firmware calls it Ultra Battery Saver) and in this mode all background processes are suspended and the alarm may not work. To turn it off, go to Settings → Battery → Power Saving Mode and select High Performance.

💡

If you often forget to turn off power saving mode, create a widget on the home screen with quick access to the battery settings. To do this, click and hold the empty space on the screen → Widgets → Find Energy Saving.
