Changing a smartphone often becomes stressful for the owner of smart gadgets, because there is a reasonable question about the fate of the accumulated statistics and settings. Fitness tracker Xiaomi Mi Band 5 is no exception, and its correct reconnection requires compliance with a certain sequence of actions. Many users mistakenly believe that it is enough to simply turn on Bluetooth on a new device, but the Mi Home ecosystem is more complex.
The migration process depends on whether you keep your phone number and your account, or if you move to a completely new platform. The first one will be as smooth as possible, the second one will require a complete reset of the bracelet. It is important to understand the storage architecture: the history of resides activity (located) in the cloud or on the old phone, not in the memory of the tracker itself.
Before you start taking action, you need to make sure that you have a stable Internet connection and battery charge of both devices. Xiaomi Mi Band 5 works in conjunction with the application Mi Fitness (formerly known as Zepp Life), which acts as the main bridge between gadgets. Ignoring the preparatory stages can lead to dissynchronization or loss of important health metrics.
Preparation of the old device and backup
The first and most critical step is to save all the data stored on your old smartphone. If you just turn off the bracelet without first synchronizing, your last workout and sleep data can be lost irrevocably. Open the Zepp Life or Mi Fitness app on your old phone and make sure that your connection status is active.
Go to the device profile and initiate manual sync by pulling the screen down or pressing the appropriate button. Xiaomi cloud server should receive the current data packets about your activity. Only after you see the current time and date of the last sync, you can move to the next step.
⚠️ Note: Do not delete the app or account on your old phone until you have made sure that all the data is displayed in the app on the new device.A local copy on your phone may be the only source of history if cloud sync has not been done.
If you plan to use the same Xiaomi account on a new phone, the process is much easier. You do not need to export anything additionally, since the activity history is tied to the account ID.
💡
Before transferring data, make sure that the old phone in the Zepp Life app has synced with Mi Fit Cloud in the profile settings.
Untie the bracelet from an old smartphone
Correct uncoupling is a guarantee that the new phone can detect the tracker without address conflicts. Bluetooth protocols often cache connections, and if the Mi Band 5 is listed as connected to the old device, the new smartphone can simply “not see” it or refuse to pair.
Go to the Bluetooth settings on your old phone, search the Mi Band 5 device list, and select "Forget the device" or "Disable." Then open the companion app, go to the bracelet profile and press the Unpair button. This action will break the logical connection between the gadgets.
- 📱 Open Bluetooth settings and delete the saved tracker profile.
- 🔄 In the Zepp Life app, click "Unpair" in your device profile.
- 🗑️ Confirm the deletion of data from the phone if the system requests confirmation.
- 🔌 Make sure the phone icon symbolizing the connection is missing on the bracelet.
After these actions are performed, the bracelet will go into the connection standby mode. The tracker screen can go out or only time and steps, which is normal behavior. The connection configuration file on the tracker side is cleared, allowing the new pair to be initiated.
☑️ Checklist of the junction
Installation of the application and registration on a new phone
The new smartphone must be equipped with the latest version of the tracker management software. For Xiaomi Mi Band 5, it is recommended to use the Zepp Life app (formerly Mi Fit) or Mi Fitness, depending on the region and version of the bracelet firmware.
When you first launch the app, you'll be asked to create a Xiaomi account or log in to an existing one. Using the same account as your old phone will automatically tighten your entire activity history if cloud sync was enabled, eliminating the need for complex database porting manipulations.
Once authorized, the app will request the necessary permissions: access to geolocation, Bluetooth, notifications and background work. Without these rights, background synchronization will not work, and you will not be able to receive notifications from messengers on your wrist.
| Annex | Compatibility | Substantive function | Region |
|---|---|---|---|
| Zepp Life | Android / iOS | Complete control and history | Global |
| Mi Fitness | Android / iOS | New interface, integration | China/Global |
| Mi Home | Android / iOS | Basic setting (rarely) | All right. |
Make sure your new smartphone’s operating system version meets the minimum application requirements. Android needs versions 6.0 and higher to work, and iOS needs versions 12.0 and higher. Outdated OSes may not support new Bluetooth encryption protocols.
The process of pairing and setting up synchronization
Now you can go directly to search for the device. In the main menu of the application, click on the device add icon (usually a plus in the corner) and select the category "Bracelet". The application will go into scanning mode of the surrounding space.
Bring the Mi Band 5 closer to the phone (no more than 1-2 meters away). The bracelet screen may show a vibration or Bluetooth icon offering to confirm pairing. Press the touch button on the tracker for confirmation if required.
The list of devices that we found should show the name Mi Band 5, which shows you the remaining battery power, click on it, and it can take 10 to 60 seconds to set up a connection, and it's about the time when you exchange encryption keys and check firmware versions.
⚠️ Warning: If the device search lasts more than 2 minutes and nothing is found, check if the bracelet is connected to another phone in the background.
Once paired successfully, the app will suggest setting up notifications, activity goals and dials. Personalization is critical at this point, because that's where you set the settings that you'll be tracking down the road. Don't skip permission screens to access contacts and messages.
What to do if the bracelet is not in place?
Data recovery and firmware update
Immediately after you connect, the app may suggest you update the tracker software. Firmware is the internal code of the device that controls its functionality. The update often contains corrections for Bluetooth stack errors, which is especially important when changing phones.
The update process looks like a progress lane in the application, while the Mi Band 5 cannot be put away from the phone or let it run out, interrupting the recording of new data can lead to a software failure that requires service intervention.
If you used the same account, your steps, sleep and pulse history will automatically be downloaded from the cloud. If the account is new, the tracker will start collecting data from scratch. In some cases, you can upload the story from the old application to the file and import it, but this does not work for all versions of the software.
- 📥 Wait for the update and start the process.
- 🔋 Make sure your bracelet is above 20% before upgrading.
- ⏳ Do not interrupt the process and keep your phone near the bracelet.
- ✅ After the update, check the operation of all sensors.
Check the time and date display correctly. Often times may be lost when changing your time zone or account region, and time synchronization occurs automatically when you connect, but sometimes requires manually running through the profile menu.
💡
Updating the firmware immediately after being tied to a new phone is a must for stable Bluetooth operation and correct transfer of settings.
Solving Typical Connection Problems
Even with strict adherence to the instructions, there can be technical nuances, and one of the common problems is the conflict of application versions. If the new phone has a Zepp Life beta installed and the bracelet is stable firmware, there can be failures in the transmission of data.
Another common mistake is the aggressive energy saving on a new smartphone. Modern Android shells (MIUI, OneUI, EMUI) often kill the background processes of the tracker application, which causes communication to break, you need to manually add the application to the battery exceptions.
If the bracelet appears in the phone's Bluetooth menu as "Connected" but says "Not Connected" in the app, try removing the device from the Bluetooth system settings and re-search the inside of the app. System pairing without the app is often incomplete.
⚠️ Warning: Never try to connect the Mi Band 5 to two phones at once through the same app, which will cause data desynchronization and possible notification errors.
In case of persistent errors, it is recommended to reset the bracelet completely through the More -> System -> Factory Reset menu and repeat the binding procedure from the beginning as a new device.
