Why Mi Band 3 is still relevant in 2026
The Xiaomi Mi Band 3 fitness bracelet, released in 2018, remains one of the most popular trackers among iPhone owners - despite the release of new Mi Band 7/8 series models. The reason lies in the optimal combination of price, functionality and compatibility with iOS. The bracelet supports tracking steps, pulse, sleep, notifications from the phone and even music management - all at a price of 2-3 times lower than counterparts from Apple or Samsung.
However, connecting the Mi Band 3 to the iPhone often raises questions among users. The main problem is that the official Mi Fit app (now Zepp Life) has limitations for iOS, and the bracelet itself requires specific Bluetooth settings. In this article, we will analyze the step-by-step instructions taking into account current firmware versions (2026), and also solve typical errors from no connection to notification problems.
