Charging
Charge your OURA Ring 4 using the dedicated charger and USB cable provided. Place the ring on the charger when the battery is low. Avoid using third-party chargers that are not specifically designed for the OURA Ring 4.
Troubleshooting
Battery Draining Quickly

- If the issue persists, contact OURA customer support for assistance.
Syncing Issues
- Verify that Bluetooth is enabled on your smartphone and the OURA App has necessary permissions.
- Ensure your OURA Ring 4 is charged and within range of your smartphone.
- Restart both your smartphone and the OURA App.
Inaccurate Readings (e.g., Heart Rate during Exercise, Stress Detection)
- The OURA Ring 4 takes heart rate readings periodically (e.g., every 10-30 minutes) and may not provide continuous real-time heart rate data during intense, dynamic exercise.
- Stress detection is based on physiological signals and can sometimes be influenced by activities like eating or exercise, which may mimic stress responses. Interpret these insights in context with your daily activities.
- Ensure the ring is worn correctly and snugly on your finger, preferably the index finger, for optimal sensor contact.
Limited Functionality Without Subscription
- The OURA Ring 4 requires an active membership to access detailed health metrics, historical data, and personalized insights.
- Without a subscription, the ring's functionality is significantly limited, primarily providing basic readiness scores without underlying data.
