How to set an alarm clock on Xiaomi Mi Band 4: 3 ways + hidden features

Why the alarm clock on the fitness bracelet and what the Mi Band 4 can do

The Xiaomi Mi Band 4 fitness bracelet has long since ceased to be just a pedometer — it’s a full-fledged assistant that monitors sleep, heart rate and even wakes you up in the morning. But many users still don’t know how to set the alarm on this device correctly so that it works steadily and does not go down. Unlike a smartphone, there are nuances here: from synchronizing with the Mi Fit app to manually adjusting it right on the bracelet screen.

In this article, we will explore all the possible ways to set an alarm clock – through the app on your phone, directly on your wristband, and also reveal the hidden Smart Alarm function, which adapts wake-up times to your sleep phases, and you will also learn why the alarm clock sometimes doesn’t work and how to fix it without resetting it.

If you've just bought a Mi Band 4 or you've been using it for a while but you've never tried an alarm clock, this is for you. We've done away with the "healthy sleep" watermarks and we're getting right to the point.

Method 1: setting the alarm clock through the Mi Fit app (most reliable)

The main and most stable method is to use the official Mi Fit app (or Zepp Life for new firmware versions), which ensures that the alarm clock will be synchronized with the bracelet even after the phone has restarted.

Here's the step-by-step instruction:

1. Open the Mi Fit app on your smartphone and make sure the bracelet is connected (a green communication icon should be on the top of the screen).
2. Go to the Profile section → Mi Smart Band 4 → Alarm clocks.
3. Click Add an alarm clock (the + icon in the upper right corner).
4. Set a time, select the days of the week (you can customize to specific days or daily) and save.

Important: After setting the alarm clock automatically syncs with the bracelet for 1-2 minutes.

• 📶 Bluetooth connection – the bracelet should be in the range of the smartphone.
• 🔄 Update firmware – in the old versions were bugs with synchronization.
• 📱 Application permissions – Mi Fit must have access to notifications and autorun.

If the alarm never appears on the bracelet, try forced synchronization: open the Profile → Mi Smart Band 4 section in Mi Fit and pull the screen down to update the data.

Method 2: Set the alarm clock directly on the Mi Band 4 bracelet

Not everyone is comfortable opening the app every time — especially if you need to add a one-time alarm, luckily, the Mi Band 4 allows you to do it right from the wristband screen, albeit with some limitations.

Algorithm of action:

1. Swipe your finger up the bracelet screen to open the menu.
2. Choose the icon Alarm clock (pictured bell).
3. Click Add ("+" icon).
4. Set time with swipes up/down (hours and minutes are set separately).
5. We choose the days of the week (check the boxes).
6. Save it by ticking the box.

Note that you can only add 10 alarm clocks on the wristband (including those set up through the app), and if the limit is exhausted, you will have to remove the old ones.

💡

To quickly turn off the alarm for one day without removing it completely, simply swipe the notification on the bracelet screen to the left and press "Delay".

The downside of this is that you can't set the vibration (it'll be standard), but the alarm will work even if the phone is off or out of Bluetooth range.

Method 3: “Smart alarm clock” – waking up in the phase of light sleep

One of the most useful but little-known features of the Mi Band 4 is the Smart Alarm, which analyzes the phases of your sleep and wakes you up in light sleep 30 minutes before your set time, which helps you wake up alert without feeling "broken."

How to turn on:

1. In the Mi Fit app, go to Profile → Mi Smart Band 4 → Alarm clocks.
2. Select an existing alarm clock or create a new one.
3. Activate the Smart Wake-up option (or Smart Wake-up in English).
4. Set a time range (by default 30 minutes to the alarm).

Important: it only works when sleep tracking is on, and if you turn off this option in your bracelet settings, the smart alarm won't work.

Users say it doesn't work perfectly -- sometimes the alarm goes off earlier than it should, or ignores sleep altogether -- but in 70 percent of cases it does help wake up easier.

If nothing helps, try resetting the bracelet settings to factory:

On the bracelet: Settings → Additional → Resetting settings


In the application: Profile → Mi Smart Band 4 → Untie the device

⚠️ Warning: All alarm clocks and activity data will be deleted after reset. synchronize the data with Mi Fit before the procedure so that you do not lose statistics.

Secret chips: how to make an alarm clock more effective

Few people know, but Mi Band 4 allows you to customize the vibration patterns for the alarm clock, which helps distinguish it from other notifications, for example, you can set three short vibrations in a row instead of one long one.

How to change it:

1. In Mi Fit, go to Profile → Mi Smart Band 4 → Notifications.
2. Select Vibration at the alarm clock.
3. Experiment with templates (e.g., Long-Short-Long).

Another life hack: if you sleep sensitively, but are afraid to sleep, set a double alarm clock:

• 🕒 First, 10 minutes before waking up (light vibration).
• 🕓 The second is at the right time (intense vibration).

For those who travel frequently, the Mi Band 4 automatically adjusts the alarm clock time when changing time zones if the phone settings enable Automatic Time Setting. But sometimes it works with a delay - check the time on the wristband after the flight!

💡

If you use a Smart Alarm, don't set your main wake-up time too early - the algorithm can wake you up 30 minutes early, which isn't always convenient.
