If your JYouPro watch isn't staying in charging mode and only briefly turns on before returning to the watch face, follow these step-by-step troubleshooting instructions to resolve the issue.

1. Inspect the Charger:
- Ensure you are using the original charging cable and power adapter that came with your watch. Non-standard chargers can cause charging issues.
- Check for any debris or damage on the magnetic charging contacts of both the watch and the charger.

2. Proper Connection:
- Make sure the magnetic charger is properly aligned with the ports on your watch. Some users report difficulty if the charger is not attached correctly. There should be a clear snap when it connects properly - learn more.

3. Charge for an Extended Period:
- Once you ensure that everything is connected correctly, leave the watch on charge for at least 30 minutes uninterrupted. It may need time to accept the charge if the battery was completely drained.

4. Soft Reset:
- If the watch continues to shut off, attempt a soft reset. Long-press the side button for about 10 seconds or until the screen flickers to see if it can revive the system - learn more.

5. Check Battery Health:
- Ensure your watch has not suffered any battery damage. If it has been exposed to extreme conditions, it may need professional attention.

6. Firmware Update:
- If you manage to get the watch to charge, check within the JYouPro app for any available firmware updates. An outdated firmware might cause functionality issues.

7. Consult the User Manual:
- Refer to the JYourPro Smart Bracelet User Manual for any specific troubleshooting advice that may pertain to your model - learn more.
