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

Synchronization of the Xiaomi Mi Band 4 fitness bracelet with the iPhone often raises questions among users - despite the cross-platform device, the nuances of the configuration in the Apple ecosystem require special attention. Unlike Android, where the process usually takes place out of the box, iPhone owners have to take into account the limitations of iOS, the features of the Mi Fit application and possible conflicts with the background processes of the system.

In this guide, we will not only look at the basic connection procedure, but also the hidden settings that the manufacturer does not advertise, from optimizing battery consumption to fine-tuning notifications. Particular attention will be paid to typical errors like the “invisibility” of the bracelet in the list of devices or problems with updating the firmware — they face up to 30% of users, according to service centers. If you have already tried to sync your gadgets and received the message “failed to connect”, here you will find a solution.

Note: the instruction is relevant for Mi Band 4 (XMSH08HM and XMSH07HM models) on firmware up to 1.0.9.54 and iPhone with iOS 14-17. Newer versions of Mi Band (5/6/7) or older iOS (below 14th) may require additional steps.

1.Preparing iPhone and Mi Band 4 for synchronization

Before setting up, make sure that both devices meet the minimum requirements:

• 📱 iPhone: iOS version 14 or later (check Settings) → Mainstream → On older versions, Mi Fit may not install or work with errors.
• 🔋 Mi Band 4: battery power at least 20%. At low charge, the bracelet can turn off during synchronization.
• 📶 Bluetooth: the iPhone should be enabled Bluetooth 4.2+ (All models starting with iPhone 5S support).
• 🌐 Internet: stable Wi-Fi or mobile network connection (required to download bracelet firmware).

Important: If you have previously used an Android bracelet, reset your settings to Mi Band 4.

1. On the bracelet, swipe your finger to the left to the point Additional.
2. Select Reset and confirm the action.

Why is this critical? Residual data from an Android device can conflict with the iOS protocol, causing synchronization errors. For example, in 15% of cases (according to the Mi Community forums), the bracelet freezes during the connection stage precisely because of undiscarded settings.

2. Installation and configuration of the Mi Fit application

The official Mi Fit app is the only supported way to manage the Mi Band 4 on the iPhone. Alternative programs (like Notify & Fitness) do not provide full functionality and may violate Apple's privacy policies.

Download Mi Fit from the App Store (direct link: here). Make sure you install a version at least 4.6.0 - older versions do not support iOS 16+.

Register a Xiaomi account (if not)

Enable geolocation for the application

Allow notifications from Mi Fit

Turn it off. VPN (It can block Xiaomi servers)-->

After installation:

1. Launch Mi Fit and sign in to Xiaomi account (or sign up). Use the same region as in your iPhone settings - a mismatch can lead to a "Device Not Supported" error.
2. In the app menu, click Profile → Add Device → Bracelet → Mi Smart Band 4.
3. Follow the instructions on the screen. When the system asks for notifications and Bluetooth access, be sure to confirm.

A typical problem: if after logging into the account, the application “hangs” at the stage of searching for devices, check:

• 🔄 Reboot your iPhone and bracelet.
• 📵 Make sure that the Mi Band 4 is not connected to another phone (even if it is turned off, the connection can be saved).
• 🛡️ Temporarily disable the ad blocker (such as AdGuard) – it can block Xiaomi servers.

3. Step-by-step synchronization of Mi Band 4 with iPhone

When the application and bracelet are ready, we proceed to pair:

1. Activate Bluetooth: on iPhone go to Settings → Bluetooth and turn it on. Mi Band 4 should appear on the list as MI Band 4_XXXX (where XXXX — unique identifier).
2. Connect to Mi Fit: In the app, click Add Device, then select Mi Smart Band 4 from the list. If the bracelet doesn't show, click Update List.
3. Confirmation on the bracelet: on the screen of the Mi Band 4 will appear a request for pairing – tap the checkmark for confirmation.
4. Update firmware: once connected, the app will offer to update the firmware of the bracelet. Don't refuse - this will fix bugs and add support for the latest versions of iOS.

The timing depends on the firmware version:

⚠️ Warning: If the update is interrupted (for example, turn off Bluetooth or close the application), the bracelet may stop responding to touch:

1. Charge the Mi Band 4 to 100%. 2. Press and hold the touch button of the bracelet for 10 seconds for a forced reboot. 3. Repeat the upgrade process.

4. Set up notifications and calls

By default, Mi Band 4 only shows notifications from standard apps (Messages, Phone) to add instant messengers (WhatsApp, Telegram) or social networks:

1. In Mi Fit, go to Profile → Mi Smart Band 4 → Notifications.
2. Turn on the Call and Message Notification switch.
3. Click Application Management and select the desired (maximum 10 applications).
4. In the iPhone settings (Settings → Notifications) for each selected application, turn on the option to Show on the lock screen.

iOS restrictions that you should know about:

• 📵 The bracelet does not display notification text from Viber and Skype (app icon only).
• 🔕 FaceTime calls are not duplicated on Mi Band 4.
• 🔋 Frequent notifications reduce the bracelet’s operating time by 15-20%.

💡

To ensure that notifications arrive without delay, in your iPhone settings, turn off the “Do Not Disturb” mode for the Mi Fit app (Settings → Do Not Disturb → Allow calls from → Mi Fit).

5. Optimization of battery consumption

Mi Band 4 on the iPhone discharges faster than on Android - this is due to the peculiarities of the background work of iOS.

• 🔋 No Notifications: 18-20 days.
• 📱 With notifications (5–10 per day): 10–12 days.
• ⚡ With active sleep/pulse monitoring: 5-7 days.

To extend the bracelet's performance:

1. Turn off your ongoing heart rate monitoring (Profile → Mi Band 4 → Heart Rate Monitor → Off.) Only turn it on while you are exercising.
2. Reduce the data synchronization frequency to 1 time every 12 hours (Settings → Data Synchronization).
3. Use dark dials (AMOLED-Mi Band 4 screen uses less energy on black).

6. Solving common problems

Even when you set it up properly, users are faced with bugs.-5 mistakes and their solutions:

1. Connect the Mi Band 4 to charging. 2. Press and hold the touch button for 30 seconds (before vibration). 3. Disconnect from charging - the bracelet will reboot in factory condition.

7. Alternative ways of connecting (without Mi Fit)
