3. Maintenance
3.1 Cleaning Your Smart Ring
To maintain the ring's appearance and sensor accuracy, clean it regularly. Use a soft, damp cloth to wipe the exterior. For the sensor area on the inside of the ring, gently wipe with a cotton swab moistened with rubbing alcohol if necessary. Avoid harsh chemicals or abrasive materials.
3.2 Battery Care
To prolong battery life, avoid extreme temperatures. Charge the ring fully when the battery is low, but avoid leaving it discharged for extended periods. While the battery lasts about 7 days, actual usage may vary.
3.3 Water Resistance Best Practices
Although the ring is IP68 waterproof, it is recommended to rinse it with fresh water after exposure to saltwater or chlorinated water to prevent residue buildup and potential long-term damage to materials.

- Difficulty Pairing: Ensure Bluetooth is enabled on your phone and the ring is charged. Try restarting both the ring and the Lefun Health app. Move the ring closer to your phone during pairing.
- Inaccurate Data: Ensure the ring fits snugly on your finger. Clean the sensors regularly. Verify that the app is updated to the latest version.
- Short Battery Life: While rated for 7 days, heavy usage or frequent data syncing can reduce battery life. Ensure the ring is fully charged. If issues persist, contact customer support.
- App Connectivity Issues: Check your phone's internet connection. Ensure the Lefun Health app has all necessary permissions enabled in your phone's settings.
