Xiaomi Mi Band 4 remains one of the most popular fitness bracelets due to its combination of affordable price, long autonomy and useful features. Among them are smart alarm clocks that wake up not with sound, but with a delicate vibration without disturbing others. However, many users face difficulties in the first setting: the alarm clock does not work, the Mi Fit application does not save changes, the vibration is too weak. In this article, we will discuss all the ways to set the alarm clocks on the Mi Band 4, including hidden functions and solutions to typical problems.
It's important to understand that the alarm clocks on the Mi Band 4 are set up exclusively through a mobile app — you can't create them directly from the wristband, and this limitation is offset by the flexibility of settings: you can set one-time or repeated signals, select days of the week, adjust the vibration intensity, and we'll also tell you how to synchronize alarm clocks with your smartphone calendar and why they sometimes disappear after updating your firmware.
Preparing for settings: what to check before setting an alarm clock
Before you start setting alarm clocks, make sure your Mi Band 4 and smartphone are ready to go. Often, setup problems arise from basic bugs that are easy to fix in advance.
First, check the firmware version of the bracelet, and the outdated software may not support some of the alarm clock functions, so you can update the firmware.
- Open the Mi Fit app.
- Go to Profile → Mi Smart Band 4 → Update firmware.
- If a new version is available, follow the instructions on the screen.
Second, make sure that the bracelet is connected to the smartphone via Bluetooth.
- 📱 On a smartphone: turn on Bluetooth in the settings.
- 🔄 In the Mi Fit app: check the connection status in the Devices section.
- 🔋 On the bracelet: if the screen does not respond, recharge it (minimum 20% charge for stable operation).
It is also worth checking the permissions of the Mi Fit application:
- 🛡️ On Android: Settings → Annexes → Mi Fit → Permissions (calendar, notifications, geodata must be included).
- 🍎 On iOS: Settings → Confidentiality → Calendar/Notifications.
⚠️ Note: If you use Mi Band 4 with iPhone, some alarm functions may not work properly due to iOS limitations.We recommend pre-sync the bracelet with Google Calendar via your Xiaomi account.
Step-by-step: how to create an alarm clock through Mi Fit
Now, let's get to the immediate settings, and it takes about 2-3 minutes, if you follow the algorithm.

⚠️ Warning: If the alarm doesn't save, try restarting the Mi Fit app and repeating the process. On Android, cleaning the app's cache also helps (Settings) → Annexes → Mi Fit → Memory. → Clear the cache).
Hidden Alarms: What the Mi Band 4 Can Do Beyond Basic Vibration
Many users are unaware that the Mi Band 4 supports advanced alarm settings, which can be activated through additional settings in Mi Fit.
Verification of the vibration intensity:
By default, the bracelet vibrates for 10 seconds with medium force.
- Go to Profile. → Mi Smart Band 4 → Settings of alarm clock → Vibration intensity.
Choose Weak, Medium or Strong.
When the vibration is strong, the battery consumption increases by 5-7% per night.
Alarm clock by phase of sleep:
This function analyzes your sleep and wakes you up in REM sleep so that you can wake up easily.
In the alarm settings, activate the Smart Alarm option.
Set a time interval (for example, 06:30–07:00) during which the bracelet will select the optimal time.
3. Google Calendar Sync: Mi Band 4 can automatically create alarm clocks based on events from the calendar.
- In Mi Fit go to Profile → Settings → Notifications → Calendar.
Select a Google account and allow access.
- Now, reminder events will be duplicated as alarm clocks on the bracelet.
| Function | How to turn it on | Features |
|---|---|---|
| Vibration intensity | Settings of alarm clock → Intensity | Strong vibration reduces autonomy |
| Smart alarm clock | Option in alarm settings | It only works with on-on sleep monitoring. |
| Synchronization with the calendar | Settings → Notifications → Calendar | Requires permission to access Google data |
| Repeated alarm clocks | Selecting the days of the week when creating | Maximum 10 active alarm clocks at the same time |
💡
If the smart alarm doesn’t work, check if sleep monitoring is enabled in the Mi Band 4 settings (Profile) → Without this option, the bracelet will not be able to analyze the phases of sleep.
Solving the Problem: Why the Alarm Doesn’t Work and How to Fix It
Even after setting the alarm clocks on the Mi Band 4 may not work, let's look at the typical causes and ways to fix them.
1. The bracelet does not vibrate at the specified time:
- 🔋 Check battery power (below 10% – alarm clocks turn off automatically).
- 🔄 Reboot the bracelet: Press the touch button 10 seconds before the Xiaomi logo appears.
- 📱 Make sure your smartphone doesn’t turn on Do Not Disturb (it can block synchronization).
2. The alarm clock disappeared after the firmware update:
- 🔄 Sync the data again: pull down on the main screen of the bracelet.
- 📲 Reinstall the Mi Fit app (sometimes cache resetting helps).
- ⚙️ Reset the bracelet settings to factory (Profile) → Untie the device, then reconnect).
3. Vibration is too weak or intermittent:
- 🔧 Check the density of the bracelet to the wrist - weak contact reduces the intensity of vibration.
- 🔋 If the battery is discharged below 30%, the vibration may become weaker.
- 📦 Update the firmware of the bracelet - in the old versions there were bugs with the driver of the vibration motor.
