Synchronization of iPhone with Xiaomi Mi Band 4: the complete guide from A to Z

Synchronizing the Xiaomi Mi Band 4 with the iPhone is a task that seems simple at first glance, but often raises questions among users. Despite the fact that both devices run on different operating systems (iOS and Mi Fit), their collaboration is possible thanks to the official application from Xiaomi.

In this article, we’ll not only explore basic Bluetooth connectivity, but also how to get around typical issues: why the bracelet doesn’t find the phone, how to turn on call notifications, and why steps data may be at odds with Apple Health.

Preparation of devices: what to do before synchronization

Before you start connecting, make sure both devices are ready to go. Let's start with the iPhone:

• 📱 Update iOS to the latest version (minimum supported iOS 12.0, but iOS 15 is recommended)+ steady-work).

• 🔋 Charge the Mi Band 4 to at least 50% – when low charge, the bracelet can turn off during synchronization.

Now on to Mi Band 4:

• ⚙️ Reset the bracelet to factory settings if it was already paired with another phone. To do this, press the touch button on the bracelet screen for 10 seconds until the vibration appears.
• 📶 Update the firmware (if the bracelet has already been used). This can be done later through the Mi Fit app.

3. Wait for the message "Device is connected." If the process is delayed, check that the iPhone is on Wi-Fi or mobile Internet (required to download the bracelet data).

• 🔔 Notifications: Enable the “Show Notifications” option and select apps (e.g. WhatsApp, Phone, Messages).
• 🚶 Steps and Activation: Activate Apple Health Sync in Profile → Settings → Connected applications.

⚠️ Attention: On iPhone with iOS 14+ Call notifications may not arrive on the bracelet if in Settings → Phone. → Call forwarding enabled "Other Devices" option. Turn it off!

If the bracelet doesn’t vibrate when notified after you’ve connected, check the Do Not Disturb settings on your iPhone – they can block the signaling to the Mi Band 4.

Set up notifications: calls, messages and applications

One of the main reasons for buying the Mi Band 4 is to be able to receive notifications from your iPhone right on your wrist, but there are limitations to Apple's ability to do so.

• 📞 Calls: The bracelet vibrates and shows the number of the incoming person, but cannot answer or reset a call (this is prohibited by Apple's policy).
• 💬 Messages: only text notifications (without emojis and pictures) are displayed. WhatsApp/Telegram You need to separately enable the option in the application settings.
• ⚠️ Limitations: Notifications only work if Mi Fit is open in the background (iOS closes background processes after 3-5 minutes).

How to set up:

1. In Mi Fit, go to Device Profile → Notifications.
2. Turn on the "Show notifications" slider.
3. Select the apps you want to see on your bracelet (maximum 10 apps).
4. For WhatsApp/Viber, additionally enable notifications in the settings of the messengers themselves (Settings → Notifications → Show Preview).

If notifications do not arrive:

• Check that the iPhone Settings → Notifications → Mi Fit includes “Allow Notifications” and “Show on the Lock screen.”
• Restart Mi Fit through the multitasking menu.
• Turn off Charge Saving mode on your iPhone – it limits the background work of apps.

Synchronizing Health Data with Apple Health

Mi Band 4 can transmit steps, sleep and heart rate data to Apple Health, but it requires:

1. Open Mi Fit and go to Profile → Settings → Connected applications.
2. Select Apple Health and enable sliders for the settings you want to sync.
3. Confirm access in the Apple Health pop-up window.

Important nuances:

• 📊 Steps: data is updated every 1-2 hours. If the discrepancy with Apple Health is greater than 10%, try manually syncing to Device Profile → Synchronize data.
• 💤 Sleep: Mi Band 4 only captures deep and light sleep, while Apple Health can add the category "Watchfulness.
• ❤️ Pulse: Transmitted to Apple Health as "Heart Rate", but only if the bracelet was worn correctly (dense to the wrist).

⚠️ Note: If you use other fitness trackers (like the Apple Watch), step data may be duplicated in Apple Health.To avoid confusion, turn off step sync for one of the devices.

💡

For accurate synchronization of sleep data, wear the Mi Band 4 on your non-working hand (left for right-handers, right for left-handers) and turn on the Do Not Disturb mode on your iPhone while you sleep.
