How much power does it save in which situations?

This would be always on regardless of ifconfig(8)'s knob, right?

     powersave
             Enable 802.11 power saving mode.  This option is generally only
             relevant to older devices where power saving is disabled by
             default.  On modern hardware, drivers will ask the firmware to
             automatically enable any applicable power-saving features.

     -powersave
             Disable 802.11 power saving mode.
