How to set an alarm clock on Xiaomi Mi Band 4: full instructions with tips

The Xiaomi Mi Band 4 fitness bracelet remains one of the most popular gadgets for tracking activity, despite the release of new models. Its key function is an alarm clock that helps you wake up on time without a sharp sound of a smartphone. However, many users face difficulties in the first setup: where to look for menus, how to sync with your phone, why the alarm clock does not work. In this article, we will analyze all the nuances from the basic setup to solving common errors.

Unlike smartphones, where the alarm clock is set up in the standard app, Mi Band 4 runs through Mi Fit (or Zepp Life for newer versions) software, which adds complexity, especially if you're first plugging in the bracelet. We'll show you every step, including hidden settings that aren't written about in the official documentation. For example, did you know that you can adjust vibrations of varying intensity for weekdays and weekends? Or that the bracelet can repeat the signal if you don't wake up the first time?

The article will be useful for both beginners and experienced users: the former will learn how to synchronize alarm clocks between the bracelet and the phone without malfunctioning, and the latter will find life hacks – for example, how to use the Do Not Disturb mode for individual alarms or why sometimes the signal is triggered with a delay.

Preparation: What you need to set the alarm clock

Before you start setting an alarm clock, make sure your Mi Band 4 is ready to go.

• 📱 Smartphone on Android 5.0+ or iOS 10.0+ with Mi Fit installed (you can download it from Google Play or App Store).
• 🔋 At least 20% charge – with low battery levels, some functions, including alarm clocks, can be turned off automatically.
• 🔄 Bluetooth sync: the bracelet must be connected to the phone (within a radius of 10 meters.
• 📅 Up-to-date firmware: check the bracelet software version in Profile → Mi Band 4 → Update of firmware: Outdated versions may not support some options.

Pay special attention to the application permissions. Mi Fit must have access to:

• 📅 Calendar (for time synchronization).
• 🔔 Notifications (to have alarm clocks duplicated on the bracelet).
• 📍 Geolocation (optional, but improves sleep tracking accuracy).

⚠️ Note: If you use Zepp Life instead of Mi Fit, the interface may be slightly different, but the logic of setting the alarm clocks remains the same.

Step-by-step: how to create an alarm clock

Now, to the main thing, add an alarm clock, follow the instructions carefully, because skipping even one step can cause the signal to fail.

1. Open the Mi Fit app and go to the Profile section (the human icon in the lower right corner).

Next, set the parameters:

After setting up, click Save. The bracelet vibrates once, which is a confirmation that the alarm clock has been added. To check if the changes have synced, go to the bracelet menu: swipe up on the home screen and find the alarm icon (🔔).

Editing and removing alarm clocks

If you need to change your wake-up time or cancel your alarm, do it in advance - Mi Band 4 does not support quick edits directly from the bracelet.

1. Open the Alarms section in the bracelet profile.
2. Put the alarm on the list.
3. Make changes (time, days of repetition, etc.) or click Remove at the bottom of the screen.
4. Save the changes – the bracelet vibrates after synchronization.

Important nuances:

• 🔄 Sync can take up to 30 seconds. If the alarm doesn't show up on the bracelet, restart the Bluetooth on the phone.
• 📵 Number limit: Mi Band 4 supports up to 10 alarm clocks at a time.
• ⏳ Delayed activation: If the bracelet has been disconnected from the phone for more than 12 hours, alarm clocks can be triggered 1-2 minutes late.

⚠️ Note: When resetting the bracelet to factory settings (Settings) → Reset on the Mi Band 4 itself, all alarm clocks are removed.

💡

If the alarm doesn't work, check the charge level of the bracelet at night. When the charge is below 10%, the vibration is automatically turned off to save energy.

Problems and Solutions: Why the Alarm Doesn't Work

Even if you set the alarm on the Mi Band 4 correctly, let’s look at the typical causes and ways to fix them:

If none of these methods worked, try reconnecting the bracelet:

1. Forget the device in your phone's Bluetooth settings.
2. Remove the Mi Band 4 from the device list in Mi Fit.
3. Reset the bracelet (press the touch button for 10 seconds).
4. Reconnect via Mi Fit.

Additional settings: signal repetition and sleep mode

Xiaomi Mi Band 4 offers advanced alarm options that many users miss.

• 🔄 Repeat signal: If you don’t wake up the first time, the bracelet will repeat the vibration in 5-10 minutes (configured in Mi Fit) → Alarm clocks → Repeat).
• 🌙 Smart alarm: the function analyzes the phases of sleep and wakes you up at the optimal moment 30 minutes before the set time. → Son → Smart alarm clock.
• 🔕 Exceptions for Do Not Disturb: You can allow the alarm to go off even when you're sleeping actively. → Don't disturb. → Exceptions.

The smart alarm function is especially useful for those who want to wake up alert. The wristband tracks when you are in REM sleep (REM) and selects the moment to wake up to avoid drowsiness. However, note that this should include a sleep tracking feature (Mi Fit → Sleep → Sleep Monitor).

Another life hack is using multiple alarm clocks at different intensity, such as:

• The first alarm clock is 6:30 with a weak vibration (to start waking up).
• The second one is at 6:45 with a strong vibration (if the first one didn't work).

⚠️ Warning: The smart alarm function may not work if you sleep less than 4 hours or go to bed later than 2 a.m. In this case, the bracelet uses standard time.

💡

For maximum accuracy of a smart alarm clock, wear the Mi Band 4 for at least 3 nights in a row, so the algorithm will better learn your sleep phases.

Comparison with other Mi Band models

If you are considering buying a new model, it is useful to know how the alarm clocks work in different versions of Xiaomi bracelets:

As you can see from the table, the Mi Band 4 is inferior to the new models in the flexibility of settings, but retains the basic features. The main advantage of the more recent versions is the ability to control alarm clocks directly from the bracelet without opening the application. However, if you only need basic alerts, the Mi Band 4 will do just as well.

Another point is app compatibility. Mi Band 4 only works with Mi Fit or Zepp Life, while the new models also support Xiaomi Wear, where the alarm clock setting interface is more modern.

In addition to the standard alarm clocks, the Xiaomi Mi Band 4 offers additional wake-up tools:

• 🌅 Sun alarm: Some firmware supports wake-up depending on the time of sunrise in your area.

• 📊 Total sleep duration.
• 🌙 Deep/light sleep and phases REM.

• 🌡️ Keep the room temperature at 18–22°C.
