Regarding WQHD+ saving more battery life than FHD+ on a black background; is the former also more efficient when the screen is off?
In addition, how is it possible than WQHD+ saves more battery life? When going to my power saving mode settings, it basically says FHD+ is more battery efficient than WQHD+. Is Samsung Power Saving Mode actually wrong in giving estimations of an increase in battery life (in hrs, mins, secs) then?
