Smart bracelets from Xiaomi have long become the standard of affordable wearable electronics, allowing you to stay connected without taking your smartphone out of your pocket. Mi Band 4, despite its age, is still very popular due to its bright brightness. AMOLED-However, many users have difficulty in initial synchronization with messengers, particularly WhatsApp.
The correct configuration of the notification system allows you to instantly respond to important messages, calls and reminders. In this article, we will discuss in detail the process of connecting the bracelet to the phone, setting access rights in the Android and iOS operating system, and also consider typical errors that interfere with vibration when incoming messages.
You will learn how to optimize the Mi Fit (or Zepp Life) application so that the operating system does not kill the background process, and how to configure the display of specific contacts.
Preparation for device synchronization
Before you start setting up, make sure that your smartphone has the official Mi Fit app or its modern analogue Zepp Life. It is through this software that you pair with the Xiaomi Mi Band 4 tracker and manage all the parameters. If the application is not already installed, download it from Google Play or the App Store and register an account.
It is important that the version of your phone’s operating system is up to date and the bracelet itself has the latest firmware available.Outdated software often contains bugs that prevent incoming messaging data from being transmitted correctly. Check for updates in the Profile –> Mi Band 4 section.
⚠️ Warning: Before pairing, make sure that Bluetooth on your smartphone is on and geolocation is on (GPS) activated, as in Android it is a mandatory requirement for Bluetooth scanning.
It's also worth checking the bracelet's charge. The process of updating the firmware or initial setup may require energy, and discharging the device in the middle of the procedure can lead to synchronization errors. If the bracelet is new, just put it on and bring it to the phone.
💡
Make sure that the Mi Fit app has constant internet access, otherwise the contact list and notification settings may not sync with the Xiaomi server.
Basic connection via Mi Fit application
Launch the app on your smartphone and go to Profile. Click on Add Device and select Mi Band 4 activity tracker from the list. The system will ask you to confirm the action by pressing the vibrator of the bracelet - this is the standard procedure for protecting against accidental connection of other devices.
Once paired successfully, the app will offer you to adjust the basic settings: time, date format, language and measurement system. At this stage, it is critical to allow all requested access immediately. If you accidentally deny access to notifications on the first run, you will later have to search for these settings deep in the phone menu.
- 📱 Allow access to contacts so that the bracelet can display the names of callers.
- 🔔 Give permission to display notifications, this is a key parameter for working with WhatsApp.
- 📍 Confirm access to geolocation for correct tracking and Bluetooth.
Now that the device is connected to the account, you can move to fine-tuning. In the app's main menu, look for the Notifications (or Alerts) section, and here's a list of all the apps that can send signals to the wrist.
☑️ Connection check
Setup to display WhatsApp notifications
In the Mi Fit notifications section, you'll see a long list of apps installed on your phone, find WhatsApp and activate the switch. From now on, the bracelet should receive signals for new messages. However, if notifications don't come, the problem most often lies not in the switch itself, but in the system permissions.
You have to go to the smartphone settings. Depending on the version of Android (MIUI, EMUI, Stock Android), the path may be slightly different, but the logic is the same: you have to find notification management for the Mi Fit (or Zepp Life) app itself and make sure that it has the "Allow Notifications" tick.
Next, go down below in the phone’s settings to “Access Notifications” (often under “Special Features” or “Security and Privacy”). This should activate the switchboard opposite the Mi Fit app. Without this permission, the operating system blocks the text from being transmitted to external devices for security purposes.
| Parameter | Status for work | Where to find out. |
|---|---|---|
| Bluetooth | Included. | Notification curtain |
| Geolocation | Included. | Settings -> Location |
| Access Mi Fit | Permitted. | Settings -> Notifications |
| Auto-start | Included. | Settings -> Appendices |
Special attention should be paid to the settings inside the WhatsApp messenger itself. Go to Settings -> Notifications inside the application and make sure that the sound and vibration for personal chats and groups are not turned off. If the phone messages come without sound, the bracelet may also be silent.
Solving problems on Android (MIUI and other shells)
Owners of Xiaomi smartphones with a shell MIUI or HyperOS are faced with an aggressive energy saving system that “kills” background processes. For Mi Fit to work stably and transmit notifications from WhatsApp, you need to prevent the system from closing this application.
Go to the battery settings, find the Mi Fit app, and select the No Limits strategy. Also, in the Auto Start menu, be sure to tick the tracker against it, which ensures that the notification service will start immediately after the phone is turned on, before the screen is unlocked.
⚠️ Note: On some versions of Android, when you turn on Do Not Disturb or No Sound, the vibration of the bracelet can be blocked by system rules.
If notifications are late, try clearing the Mi Fit app cache. Sometimes the accumulated temporary files interfere with the correct processing of incoming signals. You can do this in the Applications section -> All Apps -> Mi Fit -> Memory -> Clear the cache.
For Samsung, Huawei and Honor users, there are similar battery protection menus, such as adding an app to the list of “Sleepless Apps” on OneUI, and ignoring this step is the most common reason why the bracelet stops vibrating after hours of operation.
The Secret to a Stable Work at MIUI
Features of setting up on iOS (iPhone)
On Apple devices, the notification system works differently, and it is critical that the notification first appears in the iPhone’s Notification Center. If the WhatsApp message banner doesn’t pop up on the phone screen, it won’t come to the Mi Band 4.
Check the settings: Settings -> Notifications -> WhatsApp. Make sure the "Accept Notifications" switch is active and the banner style is set as "Temporary" or "Permanent" and the "Show in the Notification Center" check box should also be ticked.
In the Mi Fit app itself (Profile section -> "Mi Band 4" -> "Notification settings") make sure the WhatsApp switch is green. Unlike Android, there's no need to give deep system permissions here, but the Mi Fit app must have permission to send notifications in iOS settings.
- 🍏 Make sure your iPhone doesn’t turn on Do Not Disturb mode (the crescent in the control center).
- 📲 Check if notifications are closed for the Mi Fit app itself in iOS settings.
- 🔄 If you have problems, try to disable and reconnect the bracelet in the Bluetooth section of your phone settings.
Note that on iOS, the text of the message may not appear completely due to Apple’s security restrictions if the phone is locked, in which case the bracelet will show only the name of the application and the number of messages.
Vibration setting and personalization
Xiaomi Mi Band 4 allows you not only to see text, but also to feel different types of vibrations. In the application, you can choose one of the standard profiles or create your own rhythm.
In the “Bracelet settings” section -> “Vibration”, select the desired script (for example, “Notifications”). You can adjust the duration and frequency of pulses. For important contacts on WhatsApp (if the phone supports this feature and transfers it to the bracelet), you can set a unique pattern, although the bracelet usually uses a common profile for all messengers.
Also in the bracelet settings is the "Raise the wrist to turn the screen on." If it's activated, the screen will light up when you look at your hand after receiving the notification. This saves charge, since the screen is not constantly on, but only activates in motion.
It is important to know: The maximum message length that the Mi Band 4 can display is limited to about 30-40 characters (depending on font and language).
💡
A personalized vibration profile helps you instantly identify the type of event (a call or a message) without having to look at your smartphone screen.
