How to properly tie Xiaomi Mi Band 3 to a smartphone: instructions with photos and problem solving

Introduction: why you need to tie the bracelet to the phone

The Xiaomi Mi Band 3 fitness bracelet is still one of the most popular activity trackers for years, thanks to its reliability and availability. However, without the right smartphone binding, the device becomes a regular pedometer with an alarm clock. Synchronization with the phone gives access to advanced sleep statistics, notifications of calls and messages, heart rate control and even music control.

Many users have difficulty connecting for the first time: the bracelet is not detected, the app is bugged, and Bluetooth refuses to connect. In this article, we will discuss all the current methods of binding (including alternative methods for older smartphones), as well as how to avoid typical errors.

What apps support Mi Band 3 in 2026

Officially, the Xiaomi Mi Band 3 is supported by two main applications: Mi Fit (obsolete but stable) and Zepp Life (new, with advanced features).

• 📱 Mi Fit is a classic application with a minimalist interface, suitable for basic activity and sleep tracking, but updates for it are less common.
• 🌟 Zepp Life is a modern replacement from the same developer, offering detailed analytics of sleep, stress, breathing and even recommendations for improving health.+ iOS 14+), Mi Fit may not work properly.
• ⚙️ Notify & Fitness for Mi Band is a third-party software for advanced users, allowing you to configure notifications flexibly, but requires manual configuration and can conflict with official applications.

Important: from 2023, Xiaomi gradually rolls out support for Mi Fit in favor of Zepp Life. If you use an iPhone bracelet, note that Zepp Life works more stable - Mi Fit for iOS often has problems with synchronizing notifications.
