To update your Huawei Watch Ultimate to the latest HarmonyOS version, follow these steps:
1. Ensure Compatibility: The Huawei Watch Ultimate is compatible with both iOS and Android devices, but updates can only be performed through the Huawei Health app on Android devices or EMUI 10 and later versions of Huawei phones[8][9].
2. Connect to Wi-Fi: Ensure your watch is connected to a stable Wi-Fi network. This is crucial for downloading updates[11].
3. Charge Your Watch: Make sure your watch's battery level is above 45%. If it's lower, charge it before proceeding[11].
4. Open Huawei Health App: On your Android device, open the Huawei Health app. Navigate to the device details screen for your Huawei Watch Ultimate[9].
5. Check for Updates: Tap on "Firmware update" in the device details screen. The app will check for available updates. If an update is available, follow the on-screen instructions to download and install it[9].
6. Update via Watch: Alternatively, you can update directly from the watch if it's paired with a non-iPhone device. Go to Settings > System & updates > Update on your watch[9].
7. Wait for the Update: The update process may take a few minutes. Ensure your watch remains connected to Wi-Fi and powered on throughout the process.
8. Restart and Sync: Once the update is complete, restart your watch and sync it with your phone to ensure all features are working correctly.
As of now, the latest HarmonyOS version available for the Huawei Watch Ultimate is HarmonyOS 5.0, which includes features like an updated interface, offline map support, and a new Golf app[1][4][10]. If you have already received the HarmonyOS 5.0 update, you might also see subsequent minor updates like version 5.0.0.21 or 5.0.0.22, which focus on system stability optimizations[7][12].
