Ps4 Controller not blinking when charging

So i don’t know if it is really a problem or not (more an aesthetical problem I think).
My controllers won’t blink orange anymore when charging. At first I thought they won’t charge at all, but when connecting them via usb cable to my ps4 console there is a quick indication that they charge (the battery symbol on the left upper corner).
Can you guys help me out what causes this problem and how you could fix it?

It’s good. Resetting solved the problem!
