«Color pixels drain more energy than grayscale ones. Personally found my phone lasting twice as long as before.»
Is this a joke? Is there a real physical effect at play?
- SoftTalker 10mo agoI can't imagine. AFAIK no phone has "grayscale" pixels. Grey or white light is achieved by blending the other colors equally. A true monochrome screen is a thing, but they are for specialized applications and not used in phones.
- scotty79 10mo agoMaybe power draw is not linear and with grayscale rgb sub-pixels can operate at lower intensity and lower power draw than if the luminance wasn't distributed across all colors?
- boterock 10mo agosome oled displays have white subpixels, i dont know if the power cost is a thing though
- D-Machine 10mo agoThey said they noticed themselves looking at their phone far less. Most likely this is what saved the power, just a typical spurious correlation and a bad theory for the reason.
