How to reset the fitness bracelet Xiaomi Mi Band 4: a complete reset to factory settings

Why would you want to reset the Mi Band 4?

The Xiaomi Mi Band 4 fitness bracelet is one of the most popular wearables due to its combination of functionality and affordable price, but even with such a reliable gadget, there are sometimes situations when you need to return it to the factory settings, for example, you may encounter a screen freeze, sync errors with the Mi Fit application or the need to transfer the bracelet to a new owner, in which case a full reset becomes the only solution.

It is important to understand that resetting the Mi Band 4 deletes all user data: steps, pulse, alarm settings, notifications and binding to the Xiaomi account. However, the bracelet itself will remain functional after resetting – it can be reconfigured through the application. In this article, we will look at all the current methods of resetting, including software (via Mi Fit) and hardware (through the button), and also analyze the typical errors and their solutions.

If your bracelet has stopped responding to touch, does not sync with your smartphone or gives an error "failed to connect", do not rush to carry it to the service. In 90% of cases, the problem is solved by resetting to factory settings, the main thing is to follow the instructions and not interrupt the process in the middle.

Method 1: Reset via Mi Fit (recommended method)

The safest and easiest way to reset the Mi Band 4 is to use the official Mi Fit app, which is suitable if the bracelet is still responsive to commands and connects to the smartphone.

1. Open the Mi Fit app on your smartphone and make sure the bracelet is plugged in (the top of the screen should display its name, such as "Mi Smart Band 4").

This method is guaranteed to work on all versions of the Mi Band 4 firmware (including Chinese and global), as the reset is initiated by the application itself. However, if the bracelet does not connect to the phone or the application gives an error, move to the next method.

If the Mi Band 4 is getting stuck, not turning on or connecting to the phone, you can perform a hard reset with a physical button, which works even on a fully discharged bracelet (assuming that at least 5% of the charge remains to start the procedure).

4. Release the button and wait for the bracelet to reboot (usually in 20-30 seconds) and then all settings will be reset.

If the bracelet does not respond to the button holding, try the following:

• 🔋 Connect it to charging for 10-15 minutes, then try again.
• 📱 Make sure there are no physical damages on the bracelet (cracks, dents near the button).
• 🔄 Hold the button for up to 20 seconds – sometimes it takes longer.
