Xiaomi Mi Band 4 smart bracelets remain among the most popular fitness trackers due to the combination of affordable price, long autonomy and wide functionality. However, beginners often have difficulties with the first connection of the device — especially when it comes to pairing with non-Chinese versions of firmware or phones on iOS. In this article, we will analyze all the stages of setting up Step-by-step, from installing an official application to calibrating sensors and solving typical errors.
It is important to understand that the Mi Band 4 connection process is different from newer models (such as the Mi Band 7 or Smart Band 8) – it uses an outdated version of the Mi Fit app, not Zepp Life. In addition, the bracelet supports two versions of firmware: Chinese (with advanced features) and global (with restrictions).
1. Preparation for connection: what will be needed
