Using the wireless controller:
Press the PS button on the controller, and then select a user.
The time you use a controller, you'll need to register (pair) it with your PS4™
system.
Up to four controllers can be used at the same time. When you press the PS button,
the light bar will glow in a uniquely assigned color. The color that is assigned depends on
the order in which each user presses the PS button. The controller to connect is blue,
the second is red, the third is green, and the fourth is pink.
Registering (pairing) a device
The time you use a controller or when you want to use the controller on another PS4™
system, you'll need to register (pair) it with your system. Connect the controller to your system
with a USB cable while the system is on.
If you want to use two or more controllers, you must register each controller separately.

Charging:
The controller battery charges when you connect the controller to your PS4™ system with a
USB cable. The system must be turned on or in rest mode. The charge level of the battery
appears on-screen when you press and hold the PS button.
While the system is in rest mode, the light bar slowly blinks orange. When charging is
complete, the light bar turns off.
It takes approximately 2 hours to charge the controller when the battery has no
remaining charge.
Charge the controller when the temperature is between 10 °C and 30 °C (50 °F and
86 °F). You might not be able to charge the controller at other temperatures.
You'll need to completely charge the controller at least once a year to keep it
functioning properly.
Battery life varies depending on how you use the controller and the environment in
which the controller is used and stored.
To charge while the system is in rest mode, select an option other than [Off]
in (Settings) > [Power Save Settings] > [Set Features Available in Rest Mode] >
[Supply Power to USB Ports].
