Well my Ps4 has been in standby mode for about a month. Until Fallout 4 comes out I do not play Ps4 to much. If you are counting standby mode time...

I have no idea what stand by mode is on a PS4 but if its like sleep mode on a laptop then yes it is considered running all it should do is shut down the hard drive and turn off display but everything else is usually running.
