If your PlayStation 4 controller is not charging, there are a few things you can do to check. First, make sure that the power cord is plugged into an outlet and into the PlayStation 4 console. Second, make sure that the controller is plugged into the USB port on the console. Third, try plugging in a different USB cable if available. Fourth, try restarting the PlayStation 4 console and controller. Fifth, try replacing the battery in the controller if it’s possible to do so. If none of these solutions work, then your controller may need to be replaced. ..
