Preparation for connection: what to do on a smartphone before synchronization

Before you start setting up the Mi Band 4, make sure your Android smartphone meets the minimum requirements. The bracelet officially supports devices with Android version 5.0 and higher, but for stable operation it is better to use Android 7.0+.

• 📱 Free space: Mi Fit app weighs ~100MB, plus space for the data cache (more) ~50–100 MB).
• 🔋 Battery charge: the bracelet must have at least 20% charge, otherwise synchronization may be interrupted.
• 📶 Bluetooth 4.0+: supportless BLE (Bluetooth Low Energy connection will be impossible.
• 🔒 Permissions: Enable access to geodata, notifications and contacts for Mi Fit.

If you are registered with Mi Account for China, some features (such as Mi Pay) may not be available. To avoid problems, create an account for Russia or Global:

1. Go to account.xiaomi.com.
2. When registering, select the country of Russia or the United States.
3. Confirm your email or phone – this is a must for data synchronization.

Step-by-step: how to connect Mi Band 4 to Android

The synchronization process takes no more than 5 minutes if you follow a clear algorithm. Importantly, the Mi Band 4 does not support direct connection via Bluetooth Settings on your smartphone – only through the official Mi Fit app (or alternatives like Notify & Fitness).

Download Mi Fit from Google Play (avoid third-party sources, there are often modified versions with viruses).

1. Open Mi Fit and sign in to your Mi Account (or sign up).

• 🔋 Check the bracelet’s charge – at a level below 10%, it may not respond to requests.

Set up notifications: how to receive SMS, calls and messages from apps

By default, Mi Band 4 only shows incoming calls and SMS. To add notifications from WhatsApp, Telegram, VK or other instant messengers, you need to:

1. In Mi Fit, go to Profile → Mi Smart Band 4 → Application Notifications.
2. Activate the Notifications slider and select the desired apps from the list.
3. For each messenger, set up Vibration and Screen Illumination (available in firmware after 1.0.9.54).

• 📵 Notifications do not work if notifications are disabled in Android for Mi Fit settings (check Settings). → Annexes → Mi Fit → Notifications).
• 🔕 On some firmware (for example, MIUI 12+) You need to allow auto-run for Mi Fit, otherwise notifications will come with a delay.
• 📱 If notifications are duplicated, turn them off in the messenger itself (for example, in WhatsApp: Settings). → Notifications → Vibration on the bracelet).

For advanced users, if the standard settings are not suitable, you can use third-party applications like Tools & Mi Band or Mi Band Master.

• 📝 Filter keyword notifications (e.g., ignore posts with the word “advertising»).

💡

If notifications come with a delay, try turning off the power saving mode for the Mi Fit app in the Android settings.

Screen Customization: Dials, Weather and Additional Features

The Mi Band 4 supports interchangeable dials, but there are limitations to installing them: there are about 20 options officially available in the Mi Fit, but you can download third-party ones through apps like Amazfit Watchfaces (you need to manually add.bin files).

• 📊 Turn on Continuous pulse measurement in the Mi Fit settings (battery discharge will accelerate by 10-15%).
• ⚠️ Avoid measurements while moving - the bracelet only records the pulse at rest.

⚠️ Note: If the pulsemeter shows unrealistic values (for example, 200 beats per minute), reset the bracelet settings. → Mi Smart Band 4 → Untie the device, then connect again.
