How to set up Xiaomi Mi Band 3 fitness bracelet on Android: a complete guide from connectivity to hidden features

Xiaomi Mi Band 3 remains one of the most popular fitness bracelets due to its combination of affordable price, compactness and wide functionality. However, many users face difficulties when first setting up a device on Android smartphones — especially if it is about unofficial firmware, older versions of the application or conflicts with other gadgets. In this guide, we will examine not only the basic steps of connection, but also the nuances of customization, which the manufacturer often does not say.

Unlike the newer models (Mi Band 6 or Mi Band 7), the third version of the bracelet has a stripped-down interface and requires the use of the official Mi Fit app (or its alternatives like Notify & Fitness), while even after synchronization, many functions – from setting alarms to displaying notifications – remain hidden behind non-obvious menus, we will show how to avoid typical errors and unlock the full potential of the device.

Importantly, if you're upgrading with Mi Band 2, note that the Mi Band 3 has a touch button instead of a physical one, and the step-counting and sleep algorithms have been redesigned, and this can affect the usual metrics -- but once you set it up properly, the difference will be minimal.

Preparing for connection: what to do before synchronization

Before you start setting up, make sure your smartphone and bracelet are ready to go. Xiaomi Mi Band 3 is compatible with Android 4.4 and newer, but for stable operation, a version at least Android 6.0 is recommended.

• 🔋 Bracelet charge: minimum level for first setup — 20%, But it's better to charge up to 50-70%. The charging indicator lights up when connected to USB-port (cable is included in the package).
• 📱 Bluetooth Version: The bracelet supports Bluetooth 4.2, but older smartphones (until 2016 release) may have connection problems.
• 🌐 Internet connection: to download the application and update the firmware bracelet will require stable Wi-Fi or mobile Internet.

⚠️ Warning: If the bracelet has previously been paired with another smartphone, reset to factory settings. To do this, press and hold the touch button on the bracelet for 10 seconds until the vibration and the Mi logo appear.
