Reestablishing the connection between a wearable gadget and a smartphone after a complete reset is a challenge that many users of the Xiaomi ecosystem face. Often, owners of Mi Band or Amazfit devices are confused in the sequence of actions, which leads to synchronization errors and the inability to receive notifications. The correct algorithm of actions avoids double entries in the history of activity and conflicts of Bluetooth protocols.
The re-pairing process requires not just Bluetooth, but also aggregator mobile apps. Depending on your tracker model, Mi Fit, Zepp Life or Mi Fitness may be the primary tool, and understanding the differences between these platforms is critical to successful completion.
In this article, we will take a closer look at each step of connection recovery, learn how to properly delete old data, why Bluetooth cache sometimes needs to be cleared, and what hidden settings can block connection, and follow the instructions will help resuscitate the device even in difficult cases.
Preparatory stage: cleaning up old data
Before trying a new pairing, you need to completely remove traces of the previous connection from the memory of the smartphone. If you just reset the clock with a button, but left it in the list of Bluetooth devices of the phone, the system will try to connect to the old encryption keys, which will lead to an error. Go to the Bluetooth settings of your Android or iOS device, find the name of the bracelet (for example, Mi Smart Band 5) and click “Forget the device” or “Sever pairing”.
Then check the settings of the mobile app itself. Even if you delete the app and reinstall it, some files may interfere. In the Zepp Life or Mi Fitness app, make sure that there are no dead devices in the profile. If the bracelet appears to be connected but does not respond, remove it from the list of devices inside the app, not just via Bluetooth.
⚠️ Warning: Do not try to connect the watch through the standard Bluetooth menu settings Android or iOS. Direct pairing without using a proprietary app will not allow you to synchronize health data and configure notifications.
An important step is to check the version of the smartphone operating system. For the correct operation of modern versions of the watch firmware, the current version of Android (usually 6.0 and above) or iOS (12.0 and above) is required.
💡
Before starting the procedure, restart your smartphone – this will clear temporary Bluetooth stack files and often solve the problem of the “invisibility” of the device.
Choosing the Right Synchronization Application
One of the main reasons for connectivity problems is the confusion in software choice: Xiaomi's ecosystem has split into several branches in recent years, and using an inappropriate app will make connection impossible. For older models such as the Mi Band 3 and 4, as well as some versions of the Mi Band 5, Mi Fit (now renamed Zepp Life) remains the main application.
Newer devices, including the Mi Band 6, 7, 8 and Mi Watch series, often require the Mi Fitness app (or Xiaomi Wear in some regions), and installing the wrong software will cause the watch to simply not be found in the scan, or require a factory reset that you have already performed.
You can determine the desired application by the device model indicated on the back of the tracker or in the documentation, and also consider the region of the account: Chinese versions of devices sometimes require you to install the Chinese version of the application or change the region in the settings of the Mi Account account.
| Model of the device | Recommended annex | Alternative software | Features |
|---|---|---|---|
| Mi Band 3 / 4 | Zepp Life (Mi Fit) | Notify for Mi Band | Only Zepp Life for full functionality |
| Mi Band 5 / 6 | Zepp Life / Mi Fitness | - | Depends on the firmware version and region |
| Mi Band 7 / 8 | Mi Fitness | Notify for Mi Band | Zepp Life may not support new features |
| Mi Watch Lite | Mi Fitness | - | Requires mandatory authorization of Mi Account |
When downloading the application, use only official Google Play or App Store stores. Third-party sources may contain modified versions of the software that do not pass security checks and block the connection of certified devices.
Step-by-step instructions for re-conjugation
After the prep, you can switch to a direct connection. Make sure the watch is at least 20% charged and is in standby mode (the screen burns when you raise your wrist (GPS) — This is a requirement for Android smartphones when searching. BLE-device.
Launch the app you select and log in to your account. If you've used this app before, just log in. If your account is new, sign up using your phone number or email. In the main menu, click on the + icon or go to the profile to add the device.
☑️ Checklist before connection
You'll see a list of available devices on the screen. You'll see your model from the list. You'll see a request for confirmation of pairing (checkmark or vibration) on the watch screen. You'll click on confirmation. You can set up a setup process that can take anywhere from 30 seconds to 2 minutes.
During the process, the system may suggest updating the firmware of the watch. It is strongly recommended to agree to the update, as older versions of the software often contain bugs that interfere with stable connection.
⚠️ Note: If the app says “Device is busy” or “Connected to another phone” during the search process, it means that the watch is trying to connect to the previous smartphone.
Configure permissions and accesses in the Android system
Modern versions of Android (10, 11, 12, 13, 14) have strict privacy policies. To run the watch, you need to give the app an extended set of permissions. Without them, the watch can connect, but will not transmit pulse or step data.
Go to Settings → Applications → [Your app, like Zepp Life] → Permissions. Location (Always or When Used), Bluetooth, Notifications must be activated here, and some shells (MIUI, HyperOS) also require AutoRun permission.
Special attention should be paid to the energy saving settings. The system can kill the application's background process, considering it an unnecessary energy user, which leads to a break in communication with the clock. Add the application to the battery exception list or select No Limits mode.
Hidden MIUI settings for watches
To properly operate notifications (WhatsApp, Telegram, calls) you need to give the application access to notifications, this is done either through a pop-up window on the first run, or manually in the Settings → Notifications and Status bar → Access to notifications.
Solving Typical Connection Problems
Even if you follow all the instructions, there can be technical failures. One of the common problems is that the watch is visible in Bluetooth, but the app does not find it. In this case, it helps to clean the cache of Google Play services and Bluetooth itself. Go to Settings → Apps → Show system → Bluetooth → Memory → Clear the cache.
Another common situation is the “failed to connect” error in the final stage, which is often due to the fact that the phone saved a profile of the device with another device. MAC-The solution is one: in the Bluetooth application (if you have access to system files), or through the engineering menu, delete all entries about Xiaomi, then restart the phone.
- 🔄 Reboot: Banal reboot of both devices solves 80% of problems with the hanging of the Bluetooth module.
- 📶 Internet: Make sure your phone is connected to Wi-Fi or mobile internet at the time of pairing to check your account.
- 🔋 Charge: Put the clock on charge during setup – low charge can limit the power of a Bluetooth transmitter.
If nothing helps, perform a full reset of your network settings on your smartphone (Settings → Connection & Sharing → Reset Wi-Fi, Mobile Network and Bluetooth).Warning: This action will delete all stored Wi-Fi passwords and Bluetooth pairs on your phone.
💡
The most common reason for failure is the conflicting versions of the app: Remove the app, re-download it from the official one, and make sure you don't have two different fitness apps from Xiaomi at the same time.
