Dark mode could drain more battery than light mode, BBC study says

Doesn't anybody here, (including these "researchers"), understand what the >>CONTRAST<< control is for?

In dark mode, you can leave the brightness where it is, or even lower it, and use contrast to better differentiate light from dark areas, while leaving the brightness alone.

The most viewing problems occur, (at least for me), when a site is trying to be "fashionable", or "cool", or "hip" **, using something like yellow text against black background.

(** Forgive my ignorance with respect to current colloquial terms. "Fly", maybe?)
 
Well, if you have LED screen, which everyone does by now, total black means those pixels are turned off, correct me if I am wrong. That being said, many of these "dark modes" are not completely black, but dark grey or dark blue and they don't turn those pixels off to save battery life.

No, that is only for OLED or the old CRTs. On LCD, black means it is activated and blocking the LED "lamps".

This is probably why the study shows higher power usage.

Does that matter? The differences in power consumption are minimal. The BBC's testing methodology was flawed and the results laughable at best.
