Xiaomi Mi Band 4: how to connect to a smartphone in 5 minutes (with photo)

Xiaomi Mi Band 4

step-by-step instruction with illustrations

We’ll break down Android and iOS connectivity, tell you how to avoid Bluetooth issues, and give you tips on how to optimize your wristband, and if you’ve just unpacked the Mi Band 4 or bought it off your hands, this guide will save you hours of searching for solutions.

Unlike the newer models (Mi Band 5/6/7), the fourth version requires a special approach to pairing due to outdated firmware and specifics of working with the Mi Fit application. For example, Android 12+ can have problems with resolutions, and iPhone with background synchronization.

════════════════════════════════════════════════════════════════════════════

1. Preparation for connection: what to do before pairing

Before you start pairing, make sure that 3 key conditions are met:

1. Charging the bracelet. Even if the indicator shows charge, connect the Mi Band 4 to the charger for 10-15 minutes. The minimum charge level for a successful connection is 20%, otherwise the process may be interrupted during the firmware update stage.
2. Install the app. For the Mi Band 4, only Mi Fit is suitable (not to be confused with Zepp Life or Xiaomi Wear!). Download it from official stores: 📱 Google Play for Android 🍎 App Store for iOS

Pay special attention to the version of the application. If you have Mi Fit 5.0+But the bracelet doesn't find the phone, try to roll back to version 4.6.0 - it works more stable with the Mi Band 4. APK:

On the iPhone, the extra step is to allow notifications for Mi Fit in Settings → Notifications. Without that, the bracelet won't vibrate when calling and the SMS.

💡

If you have Android 10+, turn off Battery Optimization for the Mi Fit app before connecting. Otherwise, synchronization will only work when the application is open.
