If your battery drains faster than usual, try the following.

1. If you’re using real-time measurement in the app, turn it off.
2. Turn off notifications if you don’t use them.
3. If exercise mode is set to auto-detect, try switching to manual.
4. Make sure your firmware is up to date.
5. Average battery life is about 4-5 days and may vary depending on usage.

If it won’t charge, please check the following.

1. Wipe the contact surface of the charger and ring with a soft cloth.
2. Make sure the charging cable is properly connected to the USB adapter.
3. Use a USB adapter of 5W or higher.
4. Check that the LED indicator lights up during charging.
5. If none of these resolve the issue, please contact us via 1:1 Inquiry.

For accurate sleep tracking, please check the following.

1. Make sure the ring fits snugly on your finger (not too loose or too tight).
2. Wear it 30 minutes before going to bed.
3. It must be worn on the finger, not the wrist.
4. Check that the battery level is above 20%.
5. If readings are consistently inaccurate, run sensor calibration in the app.
