Just got it today (iPhone 12 Pro Max, 128gb in Pacific Blue). So far after about 10 hours of use, I'm amazed at how good it is. Obviously still honeymoon period, but the positives of the phone are really shining through. I'll have to use it for a few more days/weeks, but honestly this is so good that I might not return to android.
The hardware is amazingly good. Like, I've never held a phone this nice before. The metal edges, the weight, how sturdy it feels, it's amazing. The phone zips around super smooth and even though it has only a 60hz display, the way the OS animates and navigates, you don't really miss 90hz too much. I think my eyes have already gotten used to it. Nothing stalls the phone at all, no matter how fast I am, it constantly keeps up with ease.
The battery life is something else. I have 4 hours of screen time and still on 85% battery. Granted that's only on wifi as I was working from home, but I cannot believe how good that is. I'm not sure if it's Apple skewing the battery % so it lasts really really long at higher % levels then drops off later, but so far the battery is exceptional.
The camera is great. I do like the Pixel camera a bit more, just the way it's a bit more contrasty, but at night, this blows the Pixel 5 out of the water easy. Pixel 5 has so much noise in night shots, the iPhone is super clean. Wide angle is wider and has 2.5x optical as well. And video in HDR is amazing. The camera package overall is substantially better than the Pixel.
Now I can see why so many people love and stick with the iPhone. It's like much better version of the Pixel phones. And with Google scrapping unlimited photo backup - possibly for future Pixels, as of right now (again, still in honeymoon period) I don't have any reason to go back to the Pixel. I guess in the coming weeks the negatives will start to show up, but right now, this just does everything better, I guess except for still images, but that's a preference thing.
So very happy with my move so far. All the best with your Pixels.
