    Only midrange to high-end devices. Cheaper ones (which are very common especially in poorer countries) still use simpler LCD/LED screens.

    LCD screens have a backlight that’s always on and consumes the same amount of power regardless of what’s on the screen. OLEDs don’t have a backlight; when the screen is dark, the pixels in that area are actually turned off.
