      It kinda does if your screen is OLED. The black pixels are actually turned off on OLED screens.

      On other type of screens - like LCD - the backlight is always turned on

        Yep, but then we are talking about actually black backgrounds, which is normally a big no-no in UI design.

        A black pixel in an LCD is in the ‘on’ position with voltage applied. So dark mode uses more power on an LCD, though the number is small.
