Its combination of affordable price, reliability and rich functionality makes the device relevant for beginners and experienced users. However, many owners use only 20-30% of the bracelet’s capabilities, unaware of hidden settings, training regimes and synchronization subtleties.

In this article, we’ll look at all aspects of working with the Mi Band 4, from basic setup to advanced features like music management or screen settings, and focus on common bugs (such as why the bracelet doesn’t sync with your phone) and life hacks that save battery life, and if you’ve just unpacked your device or want to unlock its potential 100%, this guide is for you.

Before first using the Mi Band 4, you need to charge it to 100% (even if the indicator shows a partial charge).

• 🔌 Connect the bracelet to the charging cable (magnetic contacts should fit tightly).
• 📱 Install the Mi Fit app (Android/iOS) Zepp Life (a new name for some regions).
• 🔄 Turn on Bluetooth on your smartphone and allow the app to access notifications, geolocation, and physical activity.

After charging, click on the touch button of the bracelet - the Mi logo will appear on the screen. Next, follow the instructions in the application:

1. Create a Xiaomi account (or sign in to an existing one).
2. Select Add Device → Bracelet → Mi Smart Band 4
3. Bring the bracelet to the phone for automatic synchronization (distance not more than 10 cm).
4. Update the firmware if the app offers (this will fix bugs and add new features).
