How to reboot the Xiaomi Mi Band 4 fitness bracelet

Modern wearables like the Xiaomi Mi Band 4 run on real-time operating systems that, despite optimization, can fail. Users often face a situation where the tracker stops responding to touch, freezes on the screen saver or refuses to sync with the smartphone. In most cases, the only solution is to force the device to restart, which allows you to clear RAM and restart system processes.

Unlike smartphones, the fourth model of the popular fitness bracelet does not have a physical button on the body, which makes the restart procedure not obvious to beginners. There are several methods for restoring the gadget to health, from a standard software reset through the application to hardware manipulations with the charging contact. The choice of the specific method depends on whether the touch screen responds to commands or the device is in a state of complete lockdown.

Software reboot does not delete your data, but only updates the system.

Forced reboot method through charging

When the touch screen is completely unsensitive to touch, the software methods become unavailable, and in this situation, the physical impact on the power chain comes to the rescue, which simulates the extraction of the battery, which causes the power controller to initiate a hard start of the system.

You'll need an original charger or a quality analogue, as poor-quality cables may not provide the necessary current to wake the controller. Connect the fitness bracelet to the power source. If the device has been completely frozen, the connection to the power supply is not available. USB-The port often causes an automatic response of the system.
