Juli Clover at MacRumors ran the tests

I am quite surprised by the results, but I wonder if it means that the reduce transparency settings are being added on top of the transparency, because it makes no senses that removing the transparency doesn’t increase battery life. It is graphically intense and on my phone constantly glitches and has to redraw.
And here is the same glitch I have been getting with transparency with it all turned off. So I think the transparency is being rendered then covered, so that is why it doesn’t save memory by turning it off, even if everything is easier to see with the transparency turned off. And not just switching Liquid Glass to Tinted, but accessibility to Reduce Transparency.
