How to set an alarm clock on Xiaomi Mi Watch Lite: 3 proven ways + problem solving

The Xiaomi Mi Watch Lite has become a popular choice due to its combination of functionality and affordable price. But even simple operations like setting an alarm clock sometimes raise questions for new users, especially if it is about first setting up or syncing with your phone. In this article, we will explore all possible ways to set an alarm clock, from the standard method through the Mi Fitness app to little-known chips directly from the watch screens.

Many people mistakenly think that the alarm clock on the Mi Watch Lite is set up the same way as on a smartphone. In fact, there are nuances here: limits on the number of alarm clocks, features of synchronization and even hidden modes (for example, a “smart alarm clock” for sleep phases), We will not only show step-by-step instructions, but also explain why the alarm clock may not work and how to fix it.

If you just bought a watch or upgraded your firmware, this article will help you avoid common mistakes, such as the alarm clock won't work unless you sync your time to your phone or if the watch is in "Do Not Disturb" mode, and we've taken all of these things into account and prepared checklists for verification.

Method 1: Install an alarm clock through the Mi Fitness app (recommended)

The most reliable and versatile method is to use the official Mi Fitness app (formerly Mi Fit), which is suitable for all versions of the Mi Watch Lite firmware and ensures that alarm clocks are synchronized between the clock and the phone.

Here's the step-by-step instruction:

Open the Mi Fitness app on your smartphone and make sure that the Xiaomi Mi Watch Lite is connected (the top menu should show the watch model).
Go to Profile → My Devices → Xiaomi Mi Watch Lite.
Select the Alarms option (sometimes it is hidden under the Additional or Device Management menu).
Click Add an alarm and set:

⏰ Time – scroll the wheels to select hours and minutes.
🔄 Repetition – Select the days of the week (e.g., “Pn-Pt” for working days).
🔔 Signal type – vibration, sound or both (some firmwares have a choice of melody).
📴 Sync – Turn on the option if you want the alarm clock to be duplicated on your phone.

After setting up, press Save.The alarm clock automatically syncs with the clock for 1-2 minutes.If this does not happen, reset the clock (press the power button for 10 seconds) or check the Bluetooth connection.

Time is set correctly (check the time zone)

Selected the right days of repetition

Vibration or sound on.

Method 2: Set the alarm clock directly from the Mi Watch Lite screens

If you don't have access to your phone or prefer to control your watch autonomously, you can set the alarm right on the Mi Watch Lite.

❌ There is no way to choose a tune, only a standard signal.
❌ Maximum 5 alarm clocks (up to 10 can be set in the application).
❌ There is no function of a “smart alarm clock” for sleep phases.

Instructions:

On the main screen of the clock, swipe up to open the app menu.
Find the icon of the alarm clock (pictured bell) and tap it.
Click Add (+ icon at the bottom of the screen).
Set the time with the touch buttons + and -.
Choose the days of repetition by scrolling the list up and down.
Confirm the saving button ✓.

The important thing is that the alarm clocks that you create on your watch don't sync with your phone, and if you reset the clock to the factory settings, all the local alarm clocks will be removed.

💡

If the watch doesn't display the alarm icon, update the firmware via Mi Fitness. In older versions, this section may not be available.

Method 3: Smart alarm clock by sleep phases (hidden function)

Few people know, but the Xiaomi Mi Watch Lite supports a smart alarm that wakes you up in light sleep 30 minutes before your set time, which helps you wake up more alert and stress-free, but it's hidden in the settings and doesn't work on all firmware.

How to turn on:

Open the Mi Fitness app and go to Profile → Xiaomi Mi Watch Lite → Sleep settings.
Activate the Smart Alarm (or Sleep Lab in English versions).
Set the main alarm clock time (for example, 7:00).
Turn on the option to wake up in the light sleep phase and set the interval (usually 10-30 minutes).

The watch will analyze your sleep and wake you up at the optimal time, limitation: it only works when you wear hours while you sleep and your heart rate is on.

Why does a smart alarm clock not work?

1. Low battery power (less than 20%) – the watch turns off background functions. 2. Poor sleep – if the light sleep phase was not fixed, the usual alarm clock will go off. 3. No data – if you took off the watch at night or turned off sleep monitoring. 4. Outdated firmware – update the software via Mi Fitness.
