Connecting Xiaomi smart watches to iPhone: full instruction with error solutions

Synchronizing Xiaomi’s smartwatches with iPhones is a task that seems simple at first glance, but often raises questions among users.The fact is that the ecosystems of Apple and Xiaomi are not originally designed to work together: a watch on Wear OS Zepp OS They are optimized for Android, and iOS restricts access to key features through third-party apps, but that doesn’t mean that connectivity is impossible, just a few nuances.

In this article, we will not only discuss the basic steps of synchronization, but also reveal the hidden limitations of iOS when working with Xiaomi Watch, which the manufacturer rarely advertises. For example, you will learn why call notifications come with a delay, how to bypass the blocking of background activity of the Mi application. Fitness/Zepp Life and What Watch Models (Mi Band) 8 Pro, Watch 2 Pro, Watch S3) We will also explore alternative ways to connect through third-party apps like Notify for Mi Band or Tools & Mi Band, which enhance the watch’s capabilities by bypassing Apple’s restrictions.

If you've tried to connect your watch and you've encountered errors like "Device failed" or "Synchronization interrupted," at the end of the article you'll find a table that decodes the error codes and fixes them. S1) We have prepared a separate section with current workarounds, as official support for these devices in iOS often stops after firmware updates.

Xiaomi Smart Watch Compatibility with iPhone: Which Models Work?

Before you get started on the connection, it’s important to understand that not all Xiaomi smartwatches interact equally well with the iPhone, with the manufacturer dividing the devices into three categories by iOS support:

• 🟢 Full compatibility: models on the Zepp platform OS (Watch 2 Pro, Watch S3, Mi Band 8 Pro – Supports notifications, health monitoring, music management (with restrictions).
• 🟡 Partial compatibility: Mi Band 7/8, Watch S1/S2 — Work only through Mi Fitness, no sync with Apple Health and limited notices.
• 🔴 Limited functionality: older models (Mi Band 5, Amazfit Bip U) – require third-party applications, some features (for example, answering calls) are not available.

The key difference is in the application used:

⚠️ Note: If your watch model is released before 2021 (e.g. Mi Band 4 or Amazfit) GTR), Mi Fit App May Not Be Updated for iOS 16+. In this case, use alternative apps like Tools & Mi Band, but be prepared for unstable work.

2. Preparing iPhone for connection: settings and requirements

Before syncing, you need to configure your iPhone to avoid typical errors.

• 📱 iOS Version: Upgrade to the latest version (iOS 17.4)+). Older versions may not support Bluetooth 5.0, which will cause a connection to break.
• 🔄 Background Update: Enable it for the Mi app Fitness/Zepp Life in Settings → Mainstream → Updating applications in the background.
• 🔒 Permissions: Give the app access to Notifications, Bluetooth, Locations (for accurate activity tracking) and Health (if required).
• 🚫 Limits: Turn off Low Power Consumption mode – it blocks background Bluetooth activity.

Pay special attention to Bluetooth settings:

1. Go to Settings → Bluetooth.
2. Make sure the feature is on and the iPhone sees other devices (try connecting any headphones to check).
3. If the watch previously connected to another phone, reset their settings via the clock settings → Reset.

⚠️ Note: If you are using an iPhone 15 Pro or newer with a chip U2, Bluetooth 5.3 conflicts are possible on older watches (Mi Band 6 and earlier), in which case try connecting via the Notify for Mi Band app, which supports backward compatibility.

3. Step-by-step instructions: how to connect Xiaomi Watch to iPhone

Consider the process on the example of Xiaomi Watch 2 Pro and the application Zepp Life (for other models, the steps are similar, but the menu names may differ).

Step 1: Installation of the application

Download the official app from the App Store:

• For the Watch. 2 Pro/Watch S3: Zepp Life.
• For the Mi Band. 7/8: Mi Fitness.

Step 2: Registration of an account

When you first launch the app, you'll be asked to create an account.

• 📧 Email (recommended for data recovery).
• 📱 Phone number (convenient but less reliable).

2. Connect the watch through Mi Fitness.

3. In the application settings, activate the call response option.

4.Now, when an incoming call is made, you can reset it or respond directly from the clock (the sound will go through the phone).

Note: This method is unstable and can cause Bluetooth crashes.

6. Health data synchronization with Apple Health

One of the main limitations of using the Xiaomi Watch with an iPhone is that it doesn’t automatically synchronize health data with Apple Health.

If you have a Watch 2 Pro or Watch S3:

1. Open Zepp Life and go to Profile → Settings → Data Synchronization.
2. Click Connect Apple Health.
3. Select the types of data to export (steps, sleep, pulse) and confirm access.

Note: sync only works one way – from Zepp Life to Apple Health, but not the other way around.

Method 2: Health Sync (for all models)

For older models (Mi Band 7, Watch) S1):

1. Download Health Sync from the App Store.
2. Connect your Mi Fitness account in the Data Sources section.
3. Choose Apple Health as your export target.
4. Set up an automatic synchronization schedule (recommended 1 time per day).

⚠️ Note: When synchronizing data through third-party apps, you may duplicate Apple Health records or lose some information (such as sleep detailing.

7. Optimizing the iPhone watch: tips for autonomy and stability

To make Xiaomi watches work with iPhone as efficiently as possible, follow these guidelines:
