1) yes please charge it completely, the PS4 USB Port cannot give enough power to run your XIM, Mouse and Keyboard AND charge the Controller at the same time
also please deactivate the rumble/vibration of the Controller too
2) fragnstein is really bad, it works okay for CoD but for other games its inacceptabe imo
XIM gives a much much better experience
3) already have the black one which suits my desk appearance, the white one is really sexy though
