Xiaomi Mi Band 2 is one of the most popular fitness bracelets, but even time-tested gadgets have failures. If your bracelet stopped connecting to your phone, do not rush to carry it into the service: in 90% of cases, the problem can be solved independently in 5-15 minutes. The reasons range from a banal battery discharge to a conflict of firmware versions, and the solutions depend on the smartphone model, the version of the Mi Fit application and even the operating system.
In this article, we will look at all possible scenarios, from basic checks (is Bluetooth enabled?) to complex firmware manipulations, and focus on the differences between Android and iOS, as the connection algorithms on these platforms are fundamentally different, and you will find a cross-sectional table of the bracelet and application versions, a checklist for quick diagnostics, and answers to frequent questions that are not covered in the official documentation.
If you've tried rebooting your bracelet and phone before, but the result is zero, don't stop reading. In the Mi Band 2's hidden developer settings section, you'll learn about features that aren't even talked about in service centers. And iPhone owners will need instructions to bypass iOS restrictions that make the bracelet "not see" even when Bluetooth is on.
