Connecting Xiaomi Mi Band 4 to Android phone: full instructions with photos and tips

The Xiaomi Mi Band 4 fitness bracelet remains one of the most popular wearables due to its combination of affordable price, reliability and wide functionality. However, many users have difficulties when connecting a device to a smartphone for the first time — especially if we are talking about Android devices with non-standard firmware or outdated versions of the OS. In this article, we will analyze the step-by-step synchronization process, from preparing the bracelet to setting up notifications, and consider typical errors and how to fix them.

It’s important to understand that the Mi Band 4 works through the official Mi Fit app (or its Zepp Life alternative), and the correct setup depends on several factors: Android version, phone model, and even regional features. If you have not previously used Xiaomi smart bracelets, our recommendations will help to avoid common problems – for example, when the bracelet is not detected by the phone despite the Bluetooth enabled or constantly breaks the connection. Next, you will find not only the basic instructions, but also hidden settings, which even the official guides do not talk about.

Also check that the phone is Bluetooth enabled (not only in the notification panel, but also in the system settings) and power saving mode for the Mi Fit application is turned off. These settings are often confused after OS updates.
