Smart watches Amazfit from Huami (subsidiary company Xiaomi) have long gained popularity due to their combination of functionality, design and affordable prices. However, many users encounter difficulties when connecting the device to their smartphone for the first time—especially when it comes to new models like Android - especially when we are talking about new models like Amazfit GTR 4 or Bip 5 Pro. In this article you will find not just steps for synchronization, but analysis of common errorstips for optimizing the connection, as well as answers to questions that are rarely covered in official instructions.

It is important to understand that the connection process may differ depending on the version Android (starting from Android 8.0 Oreo there were restrictions on the operation of background applications), watch model and even region of purchase. For example, Amazfit GTS 4 Mini uses a simplified pairing procedure, while Amazfit T-Rex 2 requires additional permission settings for notifications. We took into account all the nuances so that your device works the first time.

If you have already tried to connect your watch, but encountered an error like "The device could not be found" or "Synchronization was interrupted", do not rush to reset the settings. In 90% of cases, the problem is solved by adjusting the settings Bluetooth or reinstalling the application Zepp (previously Mi Fit). Next is a step-by-step guide, taking into account the latest firmware updates.

1. Preparing your phone: what you need to do before connecting

Before you start synchronizing, make sure that your smartphone meets the minimum requirements. Amazfit officially supports Android 6.0 and higher, but for stable operation a version no lower than Android 8.1is recommended. Also check:

  • 📱 Android version: go to Settings → About phone → Android version. If you have Android 5.x or lower, update the system or use another phone.
  • 🔄 Free space: application Zepp weighs ~100 MB, plus you will need space for the cache and watch firmware updates (up to 500 MB).
  • 📶 Internet connection: to download the application and firmware you need Wi-Fi or mobile data with traffic of at least 300 MB.
  • 🔒 Permissions: disable "Battery optimization" for the application Zepp (instructions below).

Critical point: If you have apps installed on your phone to clear the cache (for example, Clean Master or CCleaner), temporarily remove them. They can block background work Zeppwhich will lead to synchronization failures. Also check if the mode is enabled "Battery saving" —it limits the work Bluetooth.

⚠️ Attention: On some phones Xiaomi, Redmi or POCO the function is activated by default "Auto-launch applications". Without disabling it for Zepp the watch may turn off after 5-10 minutes of inactivity.

2. Installing and setting up the Zepp application

The official application for controlling the clock Amazfit is called Zepp (previously Mi Fit). It can be downloaded:

  • 📥 Google Play: link (check that the developer is Huami Inc.).
  • 🌍 Official website: if your phone does not support Google Play (for example, Huawei without Google services), download the APK from zepp.com.
  • 🛡️ Security check: before installing the APK, check the file hash (for example, via VirusTotal) to avoid fake versions.

After installation:

  1. Open Zepp and select a language (we recommend "Russian" for completeness of translations).
  2. Register an account via email, phone number or Google/Facebook. Important: link your account to your email - this will make it easier to restore data when changing phone.
  3. In the menu "Profile → Settings → Notifications" enable all permissions (see table below).

If you use a phone with MIUI (Xiaomi), EMUI (Huawei) or One UI (Samsung), after installing Zepp, be sure to add it to list of "Protected applications". Otherwise, synchronization will be interrupted every 15–30 minutes.

3. Step-by-step connection of an Amazfit watch to a phone

Now let's move on to the pairing process itself. Make sure the clock charged at least 50% —if the battery is low, it may turn off during setup. Next:

  1. Turn on Bluetooth on your phone (Settings → Connections → Bluetooth).
  2. Activate the watch: press and hold the physical button on the case until vibration (on Bip 5 - 3 seconds, on GTR 4 - 5 seconds).
  3. Run Zepp and tap "Add device" (icon "+" in the upper right corner).
  4. Select model from the list. If your model is not available, select "Other device" and enter the name manually.
  5. Follow the instructions on the screen: the application will prompt you to confirm the code on the watch (usually 1234 or 0000).
  6. Wait for the firmware update (if available). This may take up to 20 minutes - do not interrupt the process!

What to do if the watch is not located? Check:

  • 🔋 Watch charge (battery indicator should be displayed on the screen).
  • 📵 Distance between devices (maximum 1 meter when first connected).
  • 🔄 Restart Bluetooth on your phone (Settings → Bluetooth → Off/On).
  • 📱 Remove the watch from the list of paired devices (Bluetooth settings → Amazfit XXX → Forget).

    7. Optimizing operation: how to extend battery life and improve sensor accuracy

    After successful connection, it is worth setting up the clock for maximum autonomy and measurement accuracy. Here are expert tips:

    • 🔋 Battery saving:
      • Disable "Raise your wrist to activate" (if not needed).
      • Reduce screen brightness up to 2–3 bars.
      • Turn on "Sleep mode" at night (disables notifications).
    • 📊 Sensor accuracy:
      • To measure your heart rate, wear the watch 2-3 cm above your wrist 2–3 cm above the wrist.
      • Calibrate the pedometer once a week (walk 100 steps and compare with the data in Zepp).
      • Update the firmware every 1-2 months.
    • 🛡️ Security:
      • Enable "Search for device" in Zepp (will help you find your watch if you lose it).
      • Set "Screen lock" to watch (PIN code).

    Tip for athletes: if you are running or cycling, turn on "GPS + GLONASS" in the training settings for greater track accuracy. But remember that this reduces battery life by 30–40%.

    8. Alternative connection methods (without Zepp)

    In rare cases, Zepp may not work due to regional restrictions or incompatibility with custom Android firmware. Then you can use alternative methods:

    • 🌐 Application Notify & Fitness:
      • Supports basic functions (pedometer, heart rate, notifications).
      • Download: Google Play.
      • Minus: no support for firmware and some sensors (for example, SpO₂).
    • 🔧 ADB commands (for advanced users): 
      adb shell am start -n com.huami.watch.hmwatchmanager/.device.AddDeviceActivity

      This command forces the process of adding a device to Zeppif it does not open.

    • 📱 Using a second phone:
      • If the main phone is not compatible, connect the watch to another device with Android 8.0+.
      • After setup, return to your main phone (the data will be saved in your Zepp account).
⚠️ Attention: Alternative applications like Notify & Fitness may not support new models Amazfit (for example, GTR 4 or Bip 5 Pro). Before use, check compatibility on the forums (for example, 4PDA or Reddit).

FAQ: Answers to frequently asked questions

Can Amazfit be connected to an iPhone?

Yes, but with limitations. The application Zepp is available for iOS 12.0+, but some functions (for example, answering calls or setting dials) may not be available. Also, the iPhone watch runs out faster due to the way Bluetooth works in the background.

What to do if Zepp does not see the clock after resetting?

Try the following:

  1. Remove the clock from the list of devices in Zepp and in the settings Bluetooth phone.
  2. Reboot your phone and watch.
  3. Enable "Developer mode" on your watch (Settings → About device → Click 5 times on the firmware number) and activate "Debug via Bluetooth".

If that doesn't help, contact support Amazfit with logs (see spoiler above).

How to transfer data from one phone to another?

All data (steps, workouts, settings) are linked to your account Zepp. To transfer them to a new phone:

  1. Install Zepp on the new phone and log in to the same account.
  2. Connect your watch - the data is synchronized automatically.
  3. If the data does not appear, go to Zepp in "Profile → Settings → Data synchronization" and tap "Synchronize".

Why does the watch show the wrong number of steps?

Error pedometer Amazfit usually does not exceed 5–10%, but can increase when:

  • Wearing a watch on a hand with tattoos or scars (the sensor gets lost).
  • Riding in transport (vibration is perceived as steps).
  • Using a non-original strap (poor contact with the skin).

To calibrate, go 100 steps and compare the data in Zepp with the actual quantity. If the discrepancy is more than 20% reset the sensor settings (Settings → Reset data → Reset pedometer).

Can I use Amazfit without a phone?

Yes, but with limitations. In offline mode, the watch:

  • 🔵 Saves data on steps, heart rate and workouts (synchronized when connected to the phone).
  • ⏱️ Shows time, alarms and timers.
  • 🚫 Does not work: notifications, weather, music player (if there is no built-in memory).

For listening to music without a phone, models with support for Offline music (for example, Amazfit GTR 4 or GTS 4).
