How to set up Xiaomi Mi Band 3 watch: a complete guide from connectivity to fine-tuning

Xiaomi Mi Band 3 is one of the most popular fitness bracelets that combines accessibility and rich functionality. However, many users face difficulties when first setting up: the device does not sync with the smartphone, does not show notifications or counts steps incorrectly. In this article, we will analyze all the stages of setting up, from connecting to the Mi Fit app to hidden functions that are not written in the official instructions.
