Honor – Kardena smartwatch keeps loosing connection

Does your Kardena smartwatch keep disconnecting from your Honor smartphone?
This is often caused by power-saving or app management features preventing the app from staying active in the background.

1. Check Bluetooth

Make sure Bluetooth is switched on on your Honor smartphone.
Then check within the app whether the smartwatch is shown as connected.

2. Check app launch and background activity

Open your smartphone's settings and look for the options for:

• App launch
• Background activity
• Battery optimisation
• Power saving

Allow the app you’re using to remain active in the background.

ℹ️ Note:
The exact names of these settings may vary depending on your Honor model and the installed MagicOS version.

3. Check permissions

Check the app's permissions.
In particular, allow:

• Bluetooth / nearby devices
• Notifications
• Background activity
• location, if applicable

4. Enable notifications

Enable the notifications you want, both in your smartphone settings and within the app.

5. Restart your devices

Restart your smartphone and smartwatch, then open the app.

⚠️ Important:
If the app is closed in the background by the operating system, the smartwatch may still appear as a connected Bluetooth device, while syncing and notifications no longer work reliably.
💡 Tip:
If the smartwatch reconnects every time you manually open the app, check your background and power-saving settings first.
