Finally, re-sync the controller to the PS4 using the PS button. Conduct a power cycling on your PS4: Turn off your PS4 console and controller, and unplug the PS4's power cord from the outlet. Wait 5 to 10 minutes, and with the PS4 still unplugged, hold down the power button for 30 seconds to drain all its leftover energy.
A quick and easy way to turn on a PS4 is to press a button on the console itself. To use this method, press the physical Power button on your PS4. The button will feature a power icon. Your console's power indicator light will blink blue and then white, indicating that your machine has turned on. And that's it. Select “Devices”: Within the Settings menu, locate and select the “Devices” option. This will allow you to manage device settings on your PS4. Choose “Bluetooth Devices”: In the Devices menu, scroll down and choose the “Bluetooth Devices” option. This is where you can enable Bluetooth and pair external devices.
