Anyone seen this?

Hi there. Thank you for reaching out and we're sorry for the trouble. Please try to leave the remote controller on the charger for approximately 2-3 hours and check if the issue persists or use a different USB charging cable to further isolate the issue. If the problem persists, I'm afraid that you may consider buying a new controller if your controller is no longer under warranty as the price of the repair will be more likely the same as you purchase a new controller. You may click the link below to check the availability of the said controller. Thank you for your understanding and support.

Ensure that your DJI Spark controller has the latest firmware installed. Sometimes, firmware updates include bug fixes that can resolve charging issues. If the issue persists after trying the above steps, it's advisable to contact DJI support for further assistance. They may provide specific guidance based on your situation.
