Preparation for connection: what will be needed

Before you start syncing, make sure you have everything you need, and without these components, the connection may fail or the bracelet may not work properly.

• 📱 Smartphone on Android 5.0+ or iOS 10.0+ (Bluetooth 4.0 support LE mandatory).
• 🔋 Xiaomi Mi Band 4 with a battery charge of at least 20% (at low charge, synchronization can be interrupted).
• 🌐 Stable Internet connection (for downloading applications and updates).
• 📲 Official Mi Fitness app (formerly Mi Fit) or alternative software (e.g. Notify & Fitness for Android).

If you use a Chinese version of the bracelet (for example, with the inscription NFC on the case), you may need to change the region in the application or install a special firmware, we will discuss this in the section on connection errors.

Installation of the Mi Fitness app (formerly Mi Fit)

The official Mi Band 4 management app is called Mi Fitness (formerly Mi Fit), which can be downloaded for free from Google Play or the App Store. It is important to use only the latest version, as older releases may not support new bracelet features.

Installation instructions:

2. Type in the search for Mi Fitness and select the application from the developer Xiaomi Inc.
3. Click Install and wait for the download to be completed.
