    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.

      True, but I’ve heard it’s still negligible and almost every dark mode is dark, not pure black.
