The Xiaomi Mi Band 4 fitness bracelet remains one of the most popular trackers even years after its release, thanks to the balance of price, functionality and reliability. However, many users face difficulties when connecting for the first time: the bracelet does not sync with the smartphone, does not display notifications or quickly discharges. In this article, we will analyze the step-by-step setting of the Mi Band 4 with all the nuances, and also provide video instructions for visual perception.
The Mi Band 4 feature is the lack of physical buttons (except touch on the screen), which confuses beginners. In addition, the device requires binding to the official Mi Fitness app (formerly Mi Fit), without which most of the features will not be available.
