I just noticed the proximity sensor stays awake all the time the screen is off, if "double tap to wake" feature is enabled. And if you cover the sensor then double tap does not work.
I assume proximity sensor consumes lesser battery than the screen digitizer (it does warn you on the settings page that "it reduces battery life".) So it might be a good idea to always place your phone with its screen facing down.
