6.3 Battery Care
- Charge the device regularly, avoiding complete discharge for extended periods.
- Store the watch in a cool, dry place when not in use.
- Avoid extreme temperatures, which can affect battery life.
7. Troubleshooting
- Watch not turning on: Ensure the watch is fully charged. Connect it to the magnetic charging cable and a power source for at least 30 minutes.
- Cannot pair with phone: Make sure Bluetooth is enabled on your phone and the watch is within range. Restart both the watch and your phone, then try pairing again through the Fitbeing app.
- Inaccurate heart rate/SpO2 readings: Ensure the watch is worn snugly on your wrist, about one finger's width above the wrist bone. Clean the sensor on the back of the watch. Remain still during measurements.
- GPS not tracking: Ensure you are in an open outdoor area with a clear view of the sky. Wait for the watch to acquire a GPS signal before starting your activity.
- Notifications not appearing: Check notification permissions for the Fitbeing app in your phone's settings. Ensure the app is running in the background and not being restricted by power-saving modes.
- Short battery life: Reduce screen brightness, disable continuous heart rate monitoring if not needed, and limit background app refresh. Consider using Battery Saver Mode.
8. User Tips
- Explore Watch Faces: Customize your watch face frequently to match your mood or outfit. The Fitbeing app offers a wide variety, and you can even use your own photos.

- Stay Connected: Keep your smartwatch and phone close for reliable Bluetooth call and notification functionality.
