How to tie the fitness bracelet Xiaomi Mi Band 3 to a smartphone: full instructions with solutions to problems

Why you need to tie Mi Band 3 to the phone

The Xiaomi Mi Band 3 fitness bracelet, released in 2018, is still one of the most popular activity trackers due to its reliability and availability. However, without proper synchronization with the smartphone, the device loses most of the functionality from displaying notifications to analyzing sleep and heart rate. Linking the bracelet to the phone opens up access to advanced features through the Mi Fit app (or its Zepp Life analog for new versions).

Many users have difficulty connecting for the first time: the bracelet is not detected, the application is faulty, or the sync is broken. In this article, we will analyze the step-by-step binding algorithm, discuss the features for Android and iOS, and give recommendations for solving typical problems. Particular attention will be paid to nuances that the manufacturer often misses in official instructions – for example, why the Mi Band 3 may not connect to an iPhone with the latest versions of iOS or how to reset the bracelet if it was previously tied to another device.

If you just purchased the wristband or want to reconfigure it after resetting, this guide will help you avoid common errors and save time. And for those who have tried to sync your device but have had trouble, we have prepared a section on the 10 most common problems, from lack of Bluetooth response to failures in the Mi Fit app.
