if most of the screen is dark shouldn’t that have a positive effect on battery life ?
No. Macs all use LCD screens which have the same screen brightness for every pixel (the backlight is independent of the LCD pixels).
OLED screens like in the iPhone X do benefit from Dark Mode, but no Macs offer OLED screens (yet)
In fact, strictly speaking, darkening pixels technically uses slightly more energy on LCDs, because you have to run electricity through the pixels to make them absorb some part of the light instead of just letting all wavelengths through.
I mean, it's not a huge difference overall, but still. Technically.
As the post above me says.
Technically, pure white image on LCD uses the least amount of energy.
There has already been a post on the exact same topic. Geesh.
Yeah, and not a post, posts... millions of them.
I want a MacBook with an OLED screen that won't suffer from burn in, I can dream.
