That doesn't answer the question, I'm curious too. I think there's a speed and battery advantage on the A19 Pro chip compared to the Snapdragon 8 Elite Gen 5 chip, but to know for sure one has to run the same model used in the most efficient way on both machines (flagships ios and android).

I dont think you should have been downvoted. Processing and memory are the only thing that matters. (Unless we are being so nontechnical now that we just say things like Pixel 9 is great...)
