Reconnecting a smart tracker to a smartphone is a standard procedure that many wearable electronics users face: Once fully reset, the bracelet goes into primary activation mode, completely clearing the internal memory of old profiles and encryption keys, which means that the device will no longer “recognize” your phone, even if they previously worked as a pair.
The process of re-configuring is radically different from the usual reconnection of Bluetooth in the menu of a smartphone. Trying to simply turn on Bluetooth and find the device in the list of available gadgets most often leads to an error or endless waiting for the connection. Successful synchronization requires a strictly defined algorithm of actions through a specialized application that acts as an intermediary between the phone’s operating system and the tracker’s firmware.
In this guide, we will discuss all the nuances of restoring communication, from preparing the Android or iOS operating system to entering the bracelet into pairing mode. You will learn why old Bluetooth entries can interfere with the process and how to correctly use the Mi Fitness (or Zepp Life) application to activate the device. Following the instructions will avoid typical errors and quickly return the gadget to full operation.
💡
Before starting the procedure, make sure that the bracelet is at least 20% charged to avoid suddenly shutting down during a firmware update.
Preparing a smartphone and cleaning old profiles
The first and most critical step is to completely clean up the connection history on the smartphone side. Android and iOS operating systems often cache access keys and parameters of old connections. If you try to connect the reset bracelet without removing it from the phone's memory, there will be an ID conflict, and the system will reject the new connection, considering it a duplicate.
You need to go to your device's Bluetooth system settings. Find your tracker (such as Mi Band 7 or Mi Smart Band 8) in the list of previously paired devices. Click on the gear icon or information icon next to the name and select the option "Forget the device" or "Cancel pairing." This action will delete all saved security keys.
- 📱 Open Bluetooth settings and make sure the wireless module is active.
- 🗑️ Find your bracelet in the list and follow the command “Forget the device».
- 📲 Reboot your smartphone to completely reset Bluetooth services.
- 📥 Install or upgrade the Mi Fitness (or Zepp Life) app to the latest version.
After deleting the profile, it is recommended to reboot the smartphone, which is guaranteed to clear the system caches of Bluetooth services and start the detection processes again. Also make sure that the phone has all the necessary permissions for geolocation and Bluetooth, as modern versions of Android require access to location for scanning. BLE-device.

Installation and configuration of the Mi Fitness application
The control app is the centerpiece of Xiaomi’s ecosystem. For modern models like the Mi Band 6, 7, 8 and later, the Mi Fitness app (formerly known as Xiaomi Wear) is the main tool. Older models may require Zepp Life (formerly Mi Fit).
When you first launch the app, you will be asked to create a Xiaomi account or log in to an existing one, a requirement that all your health and profile data are stored in the cloud, and without authorization, the process of adding a new device will be blocked at the software level.
The application must be given a full set of permissions, and the system will request access to:
- 🔔 Notifications (to display messages from the phone on the bracelet screen).
- 📍 Geolocation (for proper operation) GPS-tracking and device search).
- 🏃♂️ Physical activity (to synchronize steps and workouts).
- 📞 Contacts and calls (to determine the name of the caller).
Why does the app require so many permissions?
The process of introducing the bracelet into pairing mode
After resetting the bracelet automatically goes into standby mode connection. on the screen of the device usually shows the brand logo or QR-However, depending on the firmware version, the device may simply display a screen with the model name and the status "Waiting for Connection».
If the bracelet is displayed on the screen QR-You can scan the code through the Mi Fitness camera, and then click on the scanner icon in the upper right corner of the app's home screen, which is the fastest way to do this, because it immediately puts the app into device-specific search mode.
In the event of absence QR-If the camera is not reading the image, go to manual search. In the app, go to the Devices tab and click Add Device. The app will start scanning the surrounding space. Make sure the bracelet is no more than a distance away. 1-2 yards from the phone.
Path to the menu: Profile → Add device → Mi Band (select model)When your tracker appears on the list of devices found, click on its name. The bracelet screen and smartphone screen should show the same confirmation codes. Click "Confirm" on the bracelet and "Connect" in the app. The pairing process will take 5 to 15 seconds.
💡
The key is the matching of the confirmation codes on both screens – it is protection from connecting to other devices within the range of Bluetooth.
Typical Connection Errors and Their Solutions
Even if all instructions are followed, users often encounter technical problems, the most common mistake being “failed to connect” or the endless rotation of the load indicator, most often due to the fact that another service is running in the background, intercepting the connection, or the system has left “junk” from previous attempts.
Another reason may be the incompatibility of Bluetooth versions: If you have a very old smartphone (Bluetooth 4.0 and below) and a new bracelet that requires Bluetooth 5.0, stable operation is impossible, and problems arise if you have multiple applications for managing the wristbands on the phone (for example, Zepp Life, Mi Fitness and Notify for Mi Band running simultaneously), which conflict over access to the communication module.
| Symptom of error | Probable cause | Method of decision |
|---|---|---|
| No device found. | Geolocation or GPS turned off | Turn on GPS and allow the application |
| The pairing error | Old Bluetooth profile | Remove the device from Bluetooth system settings |
| Requires an in-app reset | The bracelet is tied to another account | Break the link in the previous owner’s application |
| Persistent communication breaks | Energy saving Android | Turn off energy savings for Mi Fitness |
⚠️ Note: If the app says that the device is already linked to another account, you won’t be able to connect it until the previous owner has removed it from their list of devices in the cloud.
Setting up access rights and energy saving
Once successfully connected, it is important to properly configure the application in the operating system. Aggressive algorithms for energy saving Android (especially on Xiaomi, Samsung, Huawei) can “kill” the process of the Mi Fitness application, which will lead to loss of communication with the bracelet immediately after turning off the phone screen.
You need to go to the battery settings and find the Mi Fitness app, set the "No Limits" or "Allow Background Activity" mode, and it is also recommended to pin the application to the list of running processes (usually this is done by swiping down the menu of recent apps and pressing the lock).
Please check the following parameters:
- 🔋 Allow the auto-launch of the application.
- 🔋 Turn off adaptive brightness adjustment for the app.
- 🔋 Allow work in the background.
For iOS users, the situation is simpler, but also requires attention. In Bluetooth settings, make sure that the phone icon is next to the device, and all switches are included in the settings of the Mi Fitness app itself, especially Notifications and Background Content Update.
Why does the bracelet go off at night?
Data synchronization and final calibration
Once the connection is established, the initial synchronization will begin. The bracelet may suggest updating the firmware. It is strongly recommended to agree to the update, since new versions of the software often contain corrections for Bluetooth stack errors that can interfere with the stability of the connection.
During the upgrade, don’t put your phone far from the bracelet or lock the screen if it interrupts the process (although modern versions allow locking).After the upgrade, the device will reboot and you will need to reconfigure the display dials and widgets.
At this stage, it is also recommended that:
Calibrate the pulsemeter by holding the bracelet tightly against your wrist and sitting quietly for 1-2 minutes, which will help the algorithms read the data more accurately later, and adjust the goals for steps and sleep according to your current physical parameters that you entered when you signed up for an account.
⚠️ Note: Do not attempt to sync data through third-party apps (Google Fit, Apple Health) until the initial setup is completed in the native app. Bilateral sync can create duplicate records or overwrite your new data with old archives.
