    The full Always On Display (which shows the clock + some notifications) uses less than 1% battery per hour on my ancient S7, are new phones not any better than that?

      It doesn’t if the screen is connected directly to the frame buffer which can refresh independently. Whether that’s actually implemented this way in hardware, well who knows, but I suspect it is as that’s useful to display any static image. Then just power up the display driver for a microsecond to refresh the image if needed.
