Wait, aren’t most phones OLED? Wouldn’t it be trivial to light up a few pixels in the corner of the screen when it’s off? Do phones not do this (I’m still running my S7 into the ground so I have a dedicated LED)?
It’s not trivial. An LED only needs power to light up, an OLED Pixel always needs the GPU to be powered on and it would be a significant power loss to implement a pixel sadly
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?
None of this is true. It may happen in practice on some poorly-designed devices, but the “GPU” in the SoC can remain powered off, and the display controller remain in low-power mode.

I mean there’s a ton of phones that have always on displays (AOD)

Removed by mod
OLED does see significant power benefits for black pixels but it’s no where close to lighting just a single LED
yeah samsung has a feature for this in good look
Which setting? I don’t think I see it
Huh, you’re right, I don’t see it anymore either. Could be they removed it, or maybe I’m just looking in the wrong place.
