How to Set Up Xiaomi Mi Band 3: A Complete Guide from Connection to Hidden Features

The Xiaomi Mi Band 3 remains one of the most popular fitness bracelets even years after its release, thanks to its combination of simplicity, functionality and affordable price. However, many users face difficulties in the first setup: the device does not sync, notifications do not arrive, or the bracelet discharges quickly. In this article, we will analyze all the stages of settings, from connecting to a smartphone to subtle parameters such as automatic sleep tracking or music control.

It's important to understand that the Mi Band 3 runs through the official Mi Fit or Zepp Life apps (formerly Amazfit) and their interfaces are different. We'll look at both options, and we'll also talk about how to get around common bugs. For example, why the wristband may not detect the pulse or why messages from messengers stop coming, and if you've just unpacked the device or want to reconfigure it for your needs, this is the guide for you.

Preparation for setting up: what to do before connecting

Before you start syncing the Mi Band 3 with your smartphone, follow a few mandatory steps that will save you most of the problems in the future.

First, check your phone’s compatibility. The bracelet works with Android 4.4+ or iOS 9.0+, but older versions may not have some features (like fast sync or notifications).

• 📶 Bluetooth 4.0 or later (without it, the connection will be unstable);
• 📱 Notification permission for the Mi application Fit/Zepp Life;
• 🔋 Charge bracelet at least 20% (at low charge, failures during synchronization are possible).

Second, update the firmware of the bracelet if it's been used before, and the old software may conflict with newer versions of the applications, to check the firmware's relevance:

1. Open Mi Fit or Zepp Life.
2. Go to Profile → Mi Smart Band 3 → Update firmware.
3. If a new version is available, install it without interrupting the process.

💡

If the bracelet does not respond to touch after updating, reset it to factory settings: press the touch button for 10 seconds until vibration appears.

Finally, prepare the registration data, and if you don’t already have a Xiaomi account, you’ll have to create one (via Google, Facebook, or email), and without an account, some features (such as cloud storage) will be unavailable.
