Xiaomi’s wearables have been leading the budget for years, and the fourth-generation model has become a bestseller with a color display and improved functionality. However, new owners often face the question of the right initial setup, which determines the stability of the device and the accuracy of the health data collected. The synchronization process has its nuances depending on the operating system of your smartphone, whether it is Android or iOS.
Incorrect pairing can lead to permanent communication breaks, no notifications or the inability to update the tracker firmware. In this article, we will take a detailed look at each step necessary to successfully launch your gadget and consider the typical mistakes that users face. Proper installation of the software and setting access rights is the foundation for comfortable use of a smart accessory.
Preparation for the first start of the device
Before you try to pair the tracker with a mobile phone, you need to make sure that the device itself is ready to work. Xiaomi Mi Band 4 comes with a base charge, but for the Bluetooth module to work steadily during the initial setup, the energy level should be sufficient. If you take the gadget out of the box after a long storage, it is recommended to put it on charge for at least 15-20 minutes.
The next critical step is to select and install the right app, which uses the official Mi Fit app (known as Zepp Life in some regions) to download the software exclusively from official stores: Google Play for Android or App Store for iPhone.Using third-party APK-Files can lead to malicious code installation or unstable operation.
⚠️ Warning: Do not try to connect the bracelet through the standard Bluetooth menu of your phone settings until the setup is complete in the app.This will lead to a pairing error and the device will have to be removed from the list of available gadgets to start the process anew.
It’s also worth checking your smartphone’s operating system version. Current versions of the tracker’s firmware require Android 4.4 or higher, or iOS 9.0 or later. Outdated versions of the OS may not support the necessary encryption protocols.
- 🔋 Charge the tracker to at least 20% before setting up.
- 📲 Download the Zepp Life app (formerly Mi Fit) from the official store.
- 📶 Make sure your smartphone has Bluetooth module and geolocation enabled.
- 🆔 Register for a Mi Account or sign in through third-party services (Google, Apple) ID).
Instructions for connecting to Android smartphones
Android device owners have the most extensive functionality when working with fitness trackers, but also face more stringent security restrictions. Once you install the application and register with it, you need to go to the Profile tab and select the option “Add device.” In the list of available gadgets, find Mi Band 4.
The system will request permission to use geolocation. This is not a mistake or a whim of the developers: the Bluetooth Low Energy (BLE) protocol used for communication requires access to a location to scan surrounding devices. Without GPS or geolocation permission enabled, the phone simply won't "see" the bracelet.
When a numerical confirmation code appears on the tracker screen, click on it to pair. If the code does not appear, tap the sensor on the wristband slightly. In some cases, especially on Xiaomi, Huawei or Honor smartphones, additional permissions are required in the menu of the phone itself.
☑️ Setting up access rights on Android
After a successful connection, the app will suggest updating the firmware. Upgrading to the latest firmware is critical to fix sync bugs and improve autonomy. The process can take several minutes, while keeping your phone next to your bracelet.
Configuring pairing with iPhone (iOS)
The process of connecting to Apple devices has its own features related to iOS security policy.First of all, make sure you have Bluetooth enabled in your system settings. The Zepp Life app will also request a number of permissions, including access to notifications and health (Apple Health).
Unlike Android, iPhones don’t need to turn on geolocation all the time, but you still need to access it when you first search for a device. If the bracelet isn’t there, try rebooting your smartphone – this often helps to reset the iOS Bluetooth stack cache errors.
When synchronizing health data, it’s important to prioritize correctly, and if you’re also using the Apple Watch, the data can be duplicated, and in the Zepp Life app settings, you can choose which metrics to write to Apple Health to avoid confusion in statistics.
⚠️ Note: On iOS 14 and later, the app may request permission to search for devices on the local network when it first starts. Be sure to click "Allow" or the tracker search function will not work.
- 🍏 Open your privacy settings and check Bluetooth access.
- 🏃♂️ Allow data to be recorded in the Health app for correct statistics.
- 🔔 Enable notifications for the app to receive push messages on your wrist.
- 🔄 Open the application for background data synchronization regularly.
Solving Device Detection Problems
The situation when the phone does not see the Mi Band 4 is one of the most common, most often the reason is that the bracelet has already been paired with another phone or was connected directly via the Bluetooth menu, in which case you need to perform a complete reset or deletion from the system.
Go to your smartphone’s Bluetooth settings, search the Mi Band 4 (or Mi Smart Band 4) list of devices, and click “Forget Device” or “Unpair” before repeating the search procedure through the Zepp Life app.
Secret combination for resetting
For initial pairing, the phone and bracelet must be no more than 1-2 meters apart, and the presence of metal barriers or powerful sources of radiation (routers, microwaves) can temporarily disrupt the signal stability.
If nothing works, try installing a third-party Bluetooth diagnostics app, such as Notify for Mi Band (in the trial phase), to see if the phone is seeing the device at the hardware level at all, which will help you understand where the fault is in the chain.
Configure notifications and functions in the application
Once you've successfully connected, you'll have a wide range of settings» -> «Mi Band 4 can be set to display dials. Color AMOLED-screen of the fourth model allows you to use the rich illustrations dials, which significantly change the appearance of the device.
An important part of the setup is to manage notifications, so you can choose which apps will broadcast messages to the wristband screen, but remember that every vibration and sunburn consumes battery power.
| Function | Impact on the battery | Recommendation |
|---|---|---|
| Wrist lifting | High-pitched | Disable or set the schedule |
| Heart monitoring | Medium. | 30 minutes interval |
| Notification of annexes | Medium. | Only important (messaging, calls) |
| Sleep and REM-phase | Low. | Leave it on. |
NFC configuration (in the module version) is worth special attention. To activate transport cards or contactless payment, you need to use regional versions of the application (for example, the Chinese version of Mi Fit), since this functionality is often limited or absent in the global version.
💡
To save battery power, set a schedule for the Wrist Lift function, such as turning it on only from 8:00 to 22:00, and turning it off overnight, leaving only sleep monitoring.
Frequent errors and ways to fix them
Even if you follow all the instructions, users can experience technical failures, and one of the common problems is that the bracelet connects, but the data is not synchronized, in which case it helps to clear the cache of the Zepp Life application in the phone settings or completely reinstall the program.
Another common situation is that the bracelet is constantly losing touch, which can be due to aggressive energy savings on the smartphone. Android often kills background processes to save charge, and the intermediary app is no exception.
⚠️ Note: On Xiaomi, Samsung and Huawei phones, be sure to lock the Zepp Life app in memory and remove all restrictions on background activity. Otherwise, notifications when the screen is turned off will not come.
If the bracelet is stuck and does not respond to touch, put it on the charger. Connecting to the power supply automatically reboots the device. In rare cases, a "deep discharge" is required: leave the tracker to lie down until the battery is completely discharged, and then charge it to 100%.
- 📉 Problem: No steps. Solution: Check the permissions and restart the phone.
- 🔕 Problem: No vibration. Solution: Check to see if the Do Not Disturb mode on the bracelet is on.
- 📉 Problem: Fast discharge. Solution: Turn off continuous pulse monitoring.
- 🔄 Problem: Update error. Solution: Stable Wi-Fi and phone proximity.
💡
90% of the problems with connection and operation of the Mi Band 4 are solved by correctly configuring the energy saving in the smartphone and removing the device from the system Bluetooth before re-pairing.
