If your PlayStation 4 controller isn’t charging, there could be a few things wrong. First, make sure that the controller is plugged into the PlayStation 4 and that it’s properly connected to the power outlet. If you’re using a USB cable to connect the controller to the PS4, make sure that it’s fully charged before connecting it. If you’re using an AC adapter, make sure that it’s properly plugged into an outlet and that the PS4 is turned on. If all of these things check out and your controller still isn’t charging, there could be a problem with the battery itself. If you’ve tried replacing the battery and it still doesn’t work, there might be something wrong with the connector on the battery or with the power supply unit inside of your PS4. In either case, you’ll need to take your PS4 in for repair or replacement. ..
