Synchronizing wearable electronics with a smartphone’s operating system is the first and most important step to start using all the features of a gadget. Modern trackers from a Chinese manufacturer require the presence of specialized software on a mobile device to transmit health and activity data. Without pairing correctly, the device turns into a simple watch with a minimum set of options that are not of interest to the user monitoring his condition.
The process of establishing a connection between a smart bracelet and a phone can seem difficult for a beginner because of the many nuances of the Bluetooth protocol in different versions of Android. However, if you follow a clear algorithm of actions and follow the sequence of operations, the entire procedure takes no more than five minutes. In this article, we will discuss in detail all the stages of setting up, from hardware preparation to fine calibration of notifications.
It is worth noting that the manufacturer’s ecosystem has undergone significant changes in the software structure in recent years, with Mi Fit being the main control center, now the newer Mi Fitness platform (formerly known as Zepp Life for some models) being prioritized. Understanding these differences is critical, as trying to use outdated software for new device models can lead to connection errors or incorrect display of statistics.
Preparation of the smartphone and bracelet for the first launch
Before you start looking for a device, you need to make sure that your phone is fully ready to interact with external accessories. First of all, check the battery charge of the tracker itself: if it is completely discharged, put it on charge for at least 15-20 minutes. Many users face a situation where the gadget does not turn on and does not respond to touch precisely because of the deep discharge of the battery, which is often mistaken for marriage.
The second important aspect is the Bluetooth settings in the Android operating system. Make sure the wireless module is activated and, especially for modern versions of Android (starting with version 12), geolocation is enabled. BLE-Devices (Bluetooth Low Energy) and without this permission, your phone simply won’t see your bracelet in the list of available gadgets.
It is also recommended to clear the list of previously paired devices if you have previously tried to connect the same tracker or its analogue.The accumulation of "junk" entries in the Bluetooth cache often leads to addressing conflicts. Go to Bluetooth settings, find old Xiaomi or Mi Band devices in the list, and click "Forget the device" or "Unpair" to start with a clean slate.
- 🔋 Charge the tracker to at least 40% before setting up for stable work.
- 📍 Turn it on. GPS/geolocation in fast Android settings before launching the application.
- 🗑️ Remove old bracelet profiles from the Bluetooth menu if they are still there.
- 📱 Make sure that the smartphone has at least 100 MB of free memory.
⚠️ Warning: Don’t try to pair solely through the Bluetooth system menu in your phone’s settings.This is the most common error that causes the device to connect as an audio headset or not respond at all to commands. Synchronization should be carried out strictly within a specialized application.
Selecting and installing the right synchronization application
The key to successful integration is choosing the right software. There are two main applications at the moment: Mi Fitness and Zepp Life. For newcomers who bought the device in 2023-2026, it is strongly recommended to use Mi Fitness, as it is the official platform for new models such as the Mi Band 7, 8, 9 and the Redmi Smart Band series.
The software should be downloaded exclusively from trusted sources to avoid malicious code or stripped-down versions.The best option is the official Google Play Market store. If you have a Huawei or Honor smartphone without Google services, use the AppGallery store or scan it. QR-code from the instruction attached to the box for downloading APK-file.
Once you install the app, you will need to create an account or log in through an existing one (Google, Xiaomi, Apple ID). Registration is mandatory, as your entire activity history, dial settings and health data are stored in the cloud. Without authorization, the functionality of the application will be severely limited, and you will not be able to complete the binding process of the bracelet.
💡
When registering for an account, indicate your real area of residence, which determines the list of available dials, weather services and integration with local health services.
Step-by-step instructions for connecting through Mi Fitness
Launch the Mi Fitness app installed and log in to your profile. On the home screen, you'll see the Add Device button or the plus in the interface corner. Click on it and the system will automatically start scanning the space around for compatible gadgets. At which point, a request for confirmation of code pairing may appear on the bracelet screen — check the numbers and click the tick.
When your device name appears on the list (e.g. Mi Smart Band 8), tap it. The process of establishing a secure connection will begin. During this procedure, system requests for various permissions may appear on the smartphone screen: access to contacts, microphone, notifications and background work. Allow all requests, otherwise the call and message functions will not work.
Pay special attention to the stage of updating the firmware. Immediately after connecting, the application will suggest updating the bracelet software to the current version. This process can take from 5 to 15 minutes, during which the phone screen should not go out, and the bracelet should be in close proximity to the smartphone (no more than 1 meter).
☑️ Checklist of successful connection
The table below shows the main differences in the connection process for different generations of devices, which will help you navigate the nuances:
| Model of the device | Main annex | Feature of connection | Required version of Android |
|---|---|---|---|
| Mi Band 4-6 | Zepp Life / Mi Fitness | Works with both applications | Android 6.0+ |
| Mi Band 7-9 | Mi Fitness | Only Mi Fitness, old software is not supported | Android 8.0+ |
| Redmi Band | Mi Fitness | Requires a mandatory update at the first launch | Android 8.0+ |
| Mi Smart Band 4 NFC | Zepp Life | NFC functions only work in the region of release. | Android 5.0+ |
Configure access rights and permissions in Android
The most critical stage, which is 90% of all problems, is the setting of access rights in the operating system. Android, especially in the shells MIUI and HyperOS, very aggressively controls the background processes and can kill the tracker application to save energy. To prevent this from happening, you need to manually adjust the priority of the program.
Go to your phone's settings, look for the Apps section, and select Mi Fitness (or Zepp Life) from the list. Go to Battery or Energy and select No Limits or No Limits mode, which will prevent the system from forcibly closing the app, which guarantees continuous transmission of pulse and step data.
Then you need to set up autorun. In the same menu, find the Autorun switch and activate it. Without this permission, after you restart your phone, the app won't start itself, and the bracelet will lose communication by stopping recording notifications. Also check permissions to access notifications: the app menu should be able to choose which programs (WhatsApp, Telegram, call) you want to receive messages on your wrist.
Why do notification settings fly?
⚠️ Note: Owners of smartphones Xiaomi, Redmi and POCO You need to add a memory to the app, open the list of running apps, find Mi Fitness, press it, and press the lock icon, which will prevent the application from being wiped from memory when cleaning the garbage».
Solving Typical Synchronization Problems
Even if you follow all the instructions, you can have technical difficulties, and one of the common problems is that the phone sees the bracelet, but the connection is cut off at the initialization stage, and then you can completely reset the Bluetooth settings on the phone. → System system → Resetting settings → Reset Wi-Fi, mobile networks and Bluetooth.Please note that this action will remove all stored Wi-Fi passwords and associated devices.
If the bracelet is not detected at all by the app, try to change the location. Sometimes strong electromagnetic fields or microwaves running nearby cause interference in the 2.4 GHz range. Go out into the open space or into another room. Also check if the bracelet is connected to another phone in the background - it can automatically connect to the previous owner.
In cases where the application gives an error “failed to connect”, often helps to clear the cache of the application itself. Go to Settings → Applications → Mi Fitness → Storage and click “Clear cache” (do not confuse with “Clean data”, otherwise you will have to enter the username and password again).
- 🔄 Reboot both devices: both smartphone and bracelet (via the device menu).
- 📡 Turn it off. VPN Proxies and servers can block local connections.
- 🔙 Reset the bracelet to factory settings through the tracker’s menu itself.
- 📲 Remove and reinstall the Mi Fitness app from the official source.
💡
If none of the software methods worked, the problem could be the hardware of the phone's Bluetooth module or the bracelet itself. Try connecting the tracker to another smartphone for diagnosis.
