My HUAWEI wearable device and phone disconnect or cannot reconnect

My wearable device prompts that it's disconnected from my phone

• Out of range: Bluetooth connection will automatically fail when the distance between your wearable device and your phone exceeds the connection range. For example, when your phone and watch are in different rooms, Bluetooth may frequently disconnect.
• Interference in the surroundings: Make sure that your wearable device and phone are within the connection range, without strong sources of interference in between, such as microwaves, multiple Bluetooth devices, multiple routers, or multiple Wi-Fi networks. Then, check whether the issue persists.
• Incorrect pairing with iPhones: If your wearable device does not support calling, and you wish to pair it with an iPhone, you'll need to use the Huawei Health app. Pairing simply via phone Bluetooth is unstable.
• During swimming: Bluetooth signals are microwave signals, and transmissions of these signals are heavily influenced by water. Therefore, Bluetooth connection will likely fail if your wearable device is immersed in five or more centimeters of water. This is normal and please do not be concerned.

My wearable device cannot reconnect to my phone

1. Enable GPS on your phone and grant the location permission for the Huawei Health app.
   1. To enable GPS:
      • Android/EMUI phones (taking HUAWEI phones as an example): Go to Settings> Privacy > Location, enable Access my location, touch Advanced settings, and toggle on the switches for Wi‑Fi scanning and Bluetooth scanning.

        

      • iPhones (taking iOS 16.5 as an example): Go to Settings > Privacy & Security, and enable Location Services.
      • Other phones (taking Samsung S20 that runs Android 11-based One UI 3.0 as an example): Go to Settings > Location and tap the Location switch to turn it on.
   2. To grant the location permission for the Huawei Health app:
      • Android/EMUI phones (taking HUAWEI phones as an example): Open Settings, search for and access Apps, and go to Huawei Health > Permissions > Location > Allow all the time.

        

      • iPhones (taking iOS 16.5 as an example): Go to Settings > HUAWEI Health > Location, and select Always. The iOS system has a memory management mechanism, which ensures smooth system running and optimizes power efficiency by removing apps that have been running in the background for extended periods of time. If that happens, reopen the HUAWEI Health app, and check again.
      • Other phones (taking Samsung S20 that runs Android 11-based One UI 3.0 as an example): Go to Settings > Apps > Huawei Health > Permissions > Location, and toggle on Allow all the time.

        

        

        The preceding methods are for reference only. The actual interfaces may vary by phone brand and OS version. Contact your phone vendor's customer service for further assistance in enabling the related permissions.

2. Add the Huawei Health app to the list of protected background apps.

   If the Huawei Health app has been cleared from the background, Bluetooth will frequently disconnect and auto-reconnection will not work. It is strongly recommended that you add the Huawei Health app to the list of protected background apps.

   • HUAWEI phones: Swipe up from the bottom of the screen (or touch the Recent tasks icon on the navigation bar if there is a navigation bar) to enter the Recent tasks screen, find Huawei Health, and gently swipe down on it and hold to lock it. Once locked, you will see a lock icon at its upper right corner.
   • Third-party Android phones: Open the Huawei Health app, touch Devices and then your device card, touch Troubleshooting, and follow the onscreen instructions to complete the setting.

     For detailed operations on phones of different brands, see Background protection settings of the Huawei Health app.

   • iPhones: Keep the HUAWEI Health app running in the background, and do not swipe up to clear the app.
     

     If you're using an Android phone, open the Huawei Health app, go to Me > Settings > Notification management, and enable Show step count in notification panel. This is to prevent your phone OS from closing the Huawei Health app in the background.

3. When your wearable device and phone have been disconnected for a while (usually more than 10 minutes), your wearable device will stop sending frequent reconnection requests. As a result, your wearable device and phone will not reconnect immediately.
   • If your wearable device supports calling, press the side button or Up button on your wearable device to re-establish a connection.
   • If your wearable device does not support calling, open the Huawei Health app, go to Devices, and touch Connect.

   

4. If the connection can be re-established only manually by touching Reconnect in the Huawei Health app but not automatically, or manual connection via the Huawei Health app also fails, disable and then re-enable Bluetooth on your phone, unpair your wearable device from Settings on your phone, and pair and connect them again.

If the issue persists

If none of the above resolves the issue, please call the Huawei customer service hotline for further assistance.
