JDM-055 controller remains in charge even when disconnected

[kaitsu]

Hello, I have a problem with another JDM-055 controller.
Everything works fine but it always stays on as if it were charging (yellow light flashing slowly) when it is unplugged!
 and it discharges itself.
I replaced the battery and the USB port with its ribbon but the problem is still there.
Have you ever had this problem ? thank you very much

Same problem, I guess.
