Modern wearables like the Xiaomi Mi Band 3 have proven to be reliable companions in everyday life, but even the most stable equipment sometimes requires user intervention. Over time, the gadget may start to work incorrectly: stop syncing with the smartphone, hang on the boot screen or show incorrect data about the pulse and steps.
The return procedure does not require any technical knowledge, but requires careful attention to detail so as not to damage the tracker software. In this article, we will take a look at all available methods for restarting the system, from in-app software functions to hardware solutions. You will learn how to properly prepare the device to avoid losing important data about training and health.
Before you start taking drastic measures, you should make sure that the problem is really solved by resetting. Sometimes just rebooting your smartphone or reinstalling the Mi Fit application is enough. However, if you have already tried the basic methods and the situation has not changed, then deep cleaning of the memory of the bracelet is the only sure step to restore its functionality.
Preparation for the resetting procedure
The beginning of any maintenance of portable electronics should begin with a check of the level of charge. To successfully perform the operation to clean the data, the tracker battery must be charged at least 50-60%. If the battery is discharged, the process can be interrupted at the most inopportune moment, which will lead to a software failure.
The second important step is backup. While most of your activity data is stored in the Xiaomi Cloud cloud or on the application servers, local alarm settings and targets may be lost. Make sure your smartphone is connected to the Internet and the Mi Fit (or Zepp Life) app has successfully completed the latest sync.
☑️ Preparation for discharge
It’s also worth checking the version of your smartphone’s operating system. On too old versions of Android or iOS, the app can run unstable, which is sometimes mistakenly perceived as a breakdown of the bracelet itself. Updating the phone’s software can solve the problem without having to reset the tracker.
💡
Before reset, take screenshots of important alarm clock settings and targets by steps to quickly restore them after the procedure.
Software decoupling method through the application
The safest and most correct way to return the Mi Band 3 to factory settings is to use official software, which ensures that all system files are overwritten correctly and the connection to the account is broken correctly. To begin, open the Mi Fit app (in some regions it is renamed Zepp Life) on your smartphone.
Go to the device profile, usually by tapping the bracelet icon at the top of the screen or through the Profile tab. In the list of connected devices, find your tracker. You need to find the Untie or Unbind option. This action is critical, because it not only disables Bluetooth, but also initiates a command to clean the data inside the gadget itself.
⚠️ Warning: Once the decoupling is done, all data that was not synchronized with the server will be permanently lost. Make sure that the application displays current data for today.
After you confirm the action, the bracelet vibrates and returns to the screen with the QR-If the device does not respond to the disconnect command within 30 seconds, try repeating the procedure by pre-turning off and turning on Bluetooth on the phone. Sometimes the background processes of the smartphone operating system block the transmission of commands.
💡
Software denouncing through the application is the only method that guarantees the correct removal of the Xiaomi ID account from the device.
In some cases, the app may freeze while waiting for the bracelet to respond. If that happens, don't panic. Close the app completely (unload it from memory) and run it again. Device status should change to "Not connected." Now you can move on to re-pairing.
Hardware discharge via charger
If the software methods are not working or the app is not seeing the device, you can resort to the hardware method. Xiaomi Mi Band 3 does not have a physical reset button, but there is a specific sequence of actions with the charger that forcibly restarts the system.
Connect the tracker capsule to the charger, but don't insert it yet USB-You can use a connector to the power supply or computer, wait until the battery icon appears on the screen, and at this point, while charging, you need to press the touch button several times (if it responds), or just wait. 5-10 seconds, then remove the capsule from charging and insert back.
- 🔄 Repeat the extract-insert cycle» 3-5 fast-paced.
- 🔌 Make sure the contacts on the capsule and charging are clean and not oxidized.
- ⏱ The interval between actions should not exceed 2-3 seconds.
This manipulation often causes a failure in the power controller, which leads to a forced reboot of the system. It is not a complete reset to the factory settings in the classical sense, but often helps to revive the hung interface. If after a series of reboots the problem persists, then deeper intervention is required.
Why does it work?
It's worth noting that this method doesn't delete your personal data, such as the steps history stored in the wristband memory, but it can fix software errors that interfere with normal operation. If that didn't work, it may be the firmware file itself that's the problem.
Fixing Bluetooth-connection problems
Often users are looking for a way to reset when the bracelet simply stops seeing the phone. 80% of the time, the problem is not in the Mi Band 3 itself, but in the cache of the Bluetooth connection of the smartphone operating system.
Go to your phone's Bluetooth settings. Search the MI Band 3 list and click "Forget the device" or "Cancel pairing." Then it's recommended to restart the smartphone itself. This action resets the Bluetooth stack, eliminating possible addressing conflicts.
| Symptoms. | Possible cause | Decision |
|---|---|---|
| The bracelet does not vibrate when notified | Access rights in the OS are disabled | Check notification settings in Mi Fit |
| Error "Device is occupied" | Conflict with another application | Close background fitness apps |
| No search for the device is made | Bluetooth lockdown | Reboot the Bluetooth module on your phone |
| The connection is dropped. | Low battery charge | Put the bracelet on the charger. |
After cleaning the pairing list and restarting the phone, try to find the device again through the app. If the search doesn't yield results, check if the bracelet is connected to another phone nearby. Xiaomi Mi Band 3 can only support a connection to one smartphone at a time.
Updating or reflashing the tracker
If a standard reset didn't help, there may have been some critical errors in the code, and a firmware update helps. Even if you have the latest version installed, trying to "reinstall" the current version can overwrite the damaged memory sectors. In the Mi Fit app, go to the device profile and select "Refresh Updates".
The upgrade process requires a stable connection. Put the phone and bracelet side by side, preferably no more than 20-30 cm away. The smartphone screen should be on and the app is open on the bracelet status page. If the update is interrupted, the device may stop turning on, so watch the charge.
⚠️ Warning: Do not attempt to interrupt the update process or close the application until the progress scale reaches 100.
In the rare cases where an official update does not come or installation is impossible, advanced users use third-party utilities to directly flash through the computer. However, for the Mi Band 3, this method is risky and requires special adapters, so we do not recommend it to ordinary users.
💡
Re-installing the current firmware version often solves freeze problems better than simply resetting settings.
What to do after resetting settings
After successfully completing the reset procedure, your bracelet will return to the "out of the box" state. QR-Now you need to re-enter the pairing process. Open the Mi Fit app, click Add Device, and follow the instructions on the screen.
During the setup process, you will be prompted to update your firmware (if a new version is released), configure the display of the dial, set goals for steps and pulse, and be sure to turn on notifications for the desired applications (WhatsApp, Telegram, calls), since after reset, all these permissions will be disabled by default.
- 📲 Re-sign in to your Xiaomi account.
- ⌚ Select and install a new dial.
- 🔔 Include notifications for social networks and messengers.
- 🎯 Set daily activity goals.
So for the first couple of hours, watch the device work, see if the pulse is measured correctly, if the pedometer is transmitted, if everything is stable, then the procedure was successful and the problem was solved, and if the symptoms returned, it may be a hardware malfunction of the sensor or battery.
