I still have a launch day PS4. I haven't a clue which wire I'm using to charge the controllers but it isn't the one that was provided with the console. I've just checked on my blue controller that I've had charging in my PS4's USB slot for a while now. Charging status has been constantly showing it's on charge but, removing the cable shows the controller is dead and needs charging. I guess my next step is to try charge the controller using the same wire on my PC.
Could the PS4 possibly be under powering the USB slots and stopping the charge happening?
