In hindsight, I think Pixel 6 would have been fine for me too, but what's done is done
I've seen some comments in the reviews too about how the camera is a bit too aggressive now with the upgraded hardware, I'd agree there too. While the pictures have more detail to them now compared to my Pixel 5, it looks like it's still applying a lot of sharpening which I don't believe is needed anymore. Weather has been pretty crappy here though, rainy/cloudy the majority of time, so that hasn't helped me "evaluate" either.
Battery life, I haven't really been keeping track to be honest, I charged it yesterday evening since I ran it down to 10% but I can't remember when I charged it... I'm inclined to say Sunday. Today I'm at 70% with almost 3hr of screen on time and an estimate of 1d6hr left. So I guess in my use patterns, I get about 2 days.
Overall performance is great, I used to get the odd moments of lag on the Pixel 5, none of that here. Apps still seem to launch a lot quicker too.
