Connecting Mi Band 4 to Android after resetting: step-by-step guide

Resetting settings Mi Band 4 is a standard procedure when selling a device, eliminating software crashes or switching to a new smartphone. However, after this, the bracelet no longer recognizes the previous pairing, and many users face difficulties in reconnecting. Unlike new devices, where the setup process is intuitive, restoring communication after a reset requires taking into account several nuances: from the bracelet's firmware version to the Bluetooth settings on the phone.

In this article we will analyze not only the basic steps of connecting through the official application Mi Fit (or its alternatives), but also solve typical problems: why the phone “does not see” the bracelet, how to bypass synchronization errors and what to do if Mi Band 4 refuses to update the firmware. We will pay special attention to compatibility with modern versions of Android (12+) and the features of working with bracelets released for the Chinese market (CN versions).

Preparing for connection: what you need to do before pairing

Before you start connecting, make sure that your smartphone and bracelet are ready for the procedure. Skipping these steps often results in failures when searching for a device or synchronizing data.

• 🔄 Reset the bracelet settings: press the touch button on Mi Band 4 for 10 seconds until vibration appears.
• 📲 Remove the old pairing: in Mi Fit open the bracelet profile → “Unpair the device.”
• 🔋 Charge the bracelet: the charge level must be at least 20%, otherwise the connection process will be interrupted.
