Connecting Xiaomi Amazfit smartwatch to your phone: full instruction with problem solving

Introduction: Why proper synchronization is important for the clock

The Xiaomi Amazfit smartwatch is not just an accessory, but a full-fledged gadget for monitoring health, sports achievements and notifications. However, without the correct connection to the smartphone, most of the functions will remain unavailable. Many users face problems during the pairing stage: the watch is not on the list of devices, the Zepp application gives out errors, or synchronization is interrupted. In this article, we will analyze all the current ways of connection for the Amazfit GTR 4, GTS 4, Bip 5 and others, and solve typical errors.

It’s important to understand that the connection process is different for Android and iOS — we’ll look at both options. In addition, some models (like the Amazfit T-Rex 2) require additional settings to work fully with the iPhone. If you’ve tried to sync your watch but failed, check the firmware version of the watch and the Zepp app — outdated software often causes crashes.

Preparing for connection: what to do before synchronization

Before you start pairing, make sure all the preconditions are met, which will save you most of the problems during the connection phase.

• 📱 Update your smartphone operating system to the latest version (Android 8.0)+ or iOS 12+).
• 🔋 Charge the clock to at least 50% – at low charge, synchronization may be interrupted.
• 🌐 Connect your phone to the Internet (Wi-Fi or mobile data) – without this it is impossible to download the application and update the firmware of the watch.
• 📲 Remove old versions of Mi Fit or Zepp Life apps if they were installed earlier.

Pay special attention to the permissions of the application. On Android, you must manually allow access to:

• 📍 Geolocation (for tracking activity).
• 📂 Storage (for backup copies of data).
• 🔔 Notifications (to display messages on the clock).

If you connect an Amazfit watch to an iPhone, note that some features (such as answering calls through the clock) may be limited due to Apple’s policy, in which case we recommend using an Android smartphone to make the gadget work properly.

💡

If the watch has previously been connected to another phone, reset to factory settings via Settings → System → Reset on the watch itself.

Installation and configuration of the Zepp application for synchronization

The official Amazfit watch management app is Zepp (formerly Amazfit or Mi Fit), which must be downloaded and configured before connecting the device.

Step 1: Download and Registration

1. Install the Zepp app from official stores:

• 🤖 Google Play for Android.
• 🍎 App Store for iOS.

2. Launch the application and register through:

• 📧 E-mail.
• 📱 Phone number.
• 🔄 Xiaomi, Google or Apple account ID.

Step 2: Initial profile setting

After registration, the application will offer to fill in personal data:

• 👤 Sex and Date of Birth (for calorie calculation).
• 🏃 Height and weight (for tracking activity).
• 🎯 Step-by-step goals (can be changed later).

If you are using an iPhone, go to Settings → Zepp → Permissions and turn on:

• 🔄 Background update (for real-time data synchronization).
• 📍 Geolocation Services (select "Always»).

Step-by-step: how to connect the Amazfit watch to the phone

Now, the most important thing is that you pair a watch with a phone, and the instructions are universal for most models, but we'll give you some nuances for specific devices.

For Android users

1. Turn on Bluetooth on your phone and activate the watch (click the power button).

2. Open the Zepp app and click "Add Device" (the + icon in the upper right corner).

3. Select your watch model from the list. If you don't have one, click "Other device" and type the name manually.

4. Follow the instructions on the screen. The app will suggest:

• 🔗 Confirm pairing on the clock (press the button or touch the screen).
• 🔄 Update the firmware (if a new version is available).
• ⚙️ Set up notifications (allow access to messages).

For iOS users

The process is similar, but with some limitations:

• 📵 Calls in hours only work on Android.
• 📱 Notifications from third-party messengers (such as WhatsApp) may not be displayed.
• 🔋 Background synchronization works worse due to iOS limitations.

If the watch is not on the list of devices:

1. Reboot Bluetooth on your phone (turn off/on).
2. Make sure the watch is not connected to another device.
3. Check if your model supports Bluetooth 5.0 (for Amazfit GTR 4 and later).

Setup of notifications and data synchronization

After a successful connection, you need to configure notifications and data synchronization to make the clock work as efficiently as possible.

How to enable notifications from apps

1. In the Zepp app, go to Profile → My Devices → [Your Watch] → Notifications.

2. Activate the Notifications switch and select the applications you want to see on your watch (e.g. Telegram, VK, Gmail).

3.On Android, additionally allow Zepp to access notifications in your phone settings:

Settings → Applications → Zepp → Notifications → Allow

Synchronization of health data

To automatically sync your steps, sleep and heart rate data with Google Fit or Apple Health:

1. In Zepp, go to Profile → Settings → Data Synchronization.
2. Select the service (Google Fit or Apple Health) and log in.
3. Set up the synchronization frequency (recommended "Automatically").

If the data is not synchronized:

• 🔄 Restart the Zepp app.
• 📱 Check your internet connection.
• 🔋 Make sure there is enough charge on the watch (minimum 20%).

💡

For proper synchronization of sleep data, the watch should be worn on the hand for at least 4 hours in a row.

Solving common connection problems

Even when you set it up properly, users are faced with errors, and let's look at the most common ones and how to fix them.

Error: “I couldn’t connect to the device”

Causes and solutions:

• 📵 Bluetooth is off – check your phone settings.
• 🔄 Outdated firmware - update the clock through Profile → My devices. → Update of the PO.
• 📱 Conflict with another device – remove the watch from the list of conjugated gadgets in Bluetooth settings.

Error: "The device is not supported"

This error occurs if:

• 📲 You try to connect your watch to your iPhone, but the model is incompatible (e.g. Amazfit Bip Lite).
• 🔧 Zepp is outdated – update it to the App Store or Google Play.

💡

If the Amazfit GTR 4 watch doesn’t connect to an iPhone, try using the Mi Fitness app (Zepp’s alternative for older models).

Error: “Data synchronization interrupted”

This is most often related to:

• 🌐 Unstable Internet – Connect to another Wi-Fi network.
• 🔋 Low charge clocks – charge up to 30% and try again.
• 📱 Background restrictions – on Android add Zepp to battery optimization exceptions.

⚠️ Note: If after updating the firmware clock stopped synchronizing, reset through Settings → System system → Reset and reconnect. That will delete all the data from the watch, but it will bring back the work.

Additional settings for maximum functionality

After successful connection, we recommend optimizing the clock for your needs.

Setting up screens and dials

1. In the Zepp app, go to Profile → My Devices → [Your Watch] → Dials.

2. Select your favorite dial from the directory or download yours through Amazfit Watch Faces (available for Android).

3.Tune quick buttons on the watch screen (such as starting a workout or monitoring your pulse).

Activation of extended functions

Depending on the model, available:

• 🩺 Measurement SpO₂ (oxygen saturation - include in the settings → Health.
• 🏊 Swimming mode – activate in Settings → Training.
• 🔊 Voice assistant (for Amazfit) GTR 4) - connect via Settings → Voice assistant.

Optimizing the battery

To extend the working hours:

• ⏱️ Reduce your pulse rate (e.g., every 10 minutes instead of 1 minute).
• 🌙 Turn on sleep mode to turn off notifications at night.
• 📵 Turn off your Bluetooth connection (unless you need real-time notifications).

⚠️ Note: On the Amazfit Bip 5 and later, Always-on Display significantly reduces the time you run.
