im being curious about the benefits of mini-LED on battery.after all,if using dark mode ,with even just gray color (not even black) the battery should be improved no?

has anybody tested light vs dark mode ?

not in the same way as OLED might - and even then its minimal.
The more "black" the image, the more the backlight local dimming zones turn "off" which yes will save some power, but soon as you start showing much info onscreen the dimming zones aren't really small enough to make a difference - just look at the "blooming" posts/complaints and you'll see that actually each dimming zone is pretty big...

Are you just guessing or do you actually know this?

Blooming isn’t necessarily caused by more zones being lit, but simply from the inability to prevent leakage to adjacent zones.

In principle, it should save battery. There needs to be a more scientific test on this, but dark colours will darken or turn off dimming zones in the display. Yes, if a few bright pixels enter a dimming zone, then it'll have to turn on. But it won't necessarily have to go at full brightness... they tune the software and hardware to reduce the blooming.

Educated guess.
I didn't say blooming was caused by adjacent zones being lit - I said it's the size of each dimming zone is the issue...

My point being
On a pure black image - no zones lit = maximum potential power saving
Soon as its in use there are some pixels displaying 'non-black' therefore the backlight lights in those areas.
BUT
On an OLED EVERY pixel that's "black" is powered off therefore we see power savings.
On Mini-LED a pixel may be black in colour, but the dimming zone is not small enough to not light these say between lines of white text on a black page... therefore the power saving, is gonna be marginal at best.

Not to add additional complexity to your question, but in the evening you are probably turning down the over-all brightness with light mode more than you would with dark mode which means that dark mode might use more power.

That,combined with the fact that a dimmer display with light mode is more visible than a less dim(more brightness) with dark mode is still as visible,nay more
My syntax still sucks doesn't it

I've found this to be the case with Dark Mode in general. I find I'm comfortable viewing text at much lower brightness levels in light mode than in dark mode. Working on the same document but switching modes (Ulysses makes this very easy) I find I might use in a moderately-lit room, say, ~50% brightness in dark mode, but more like ~33% brightness in light mode.
