    On LCD displays dark mode actually uses more electricity; the brightness is always there, and you need to power the liquid-crystal layer to block that light to result in darker colours.

    This whole myth about darker screens saving energy goes way back to the old CRT days when it actually did save some energy.

    Yall remember Blackle?

      Many phones have OLED displays, which physically turn off the pixels in black areas. Since the site is on mobile, it does make a bit of sense.

        But then most dark modes aren’t pitch black. I guess it might save a bit of power by just being at a low brightness. Anyways I need my dark mode and also night mode.

          Less brightness means less light emitted by the diodes means less power is used. They may not turn off, but they still use less.

      In case you are using an OLED screen or one of its variants, the difference is noticeable since they turn off the pixels that are black and, therefore, less electricity is consumed.
