There are a few reasons why your PlayStation 4 controller might disconnect intermittently. One reason could be that the controller is not properly plugged in to your console. If you have trouble connecting your controller to your console, try unplugging it and plugging it back in again. Another reason could be that the battery is low and needs to be replaced. If you experience this problem, go to your PlayStation 4 system’s power outlet and plug in the controller’s power cord. If that doesn’t work, take the controller to a game store or another service that sells PlayStation 4 systems and have them look at it. Finally, if all of these solutions don’t work, you could have a defective controller.
