About the large size of the iPhone 12 Pro Max. Is it a big phone? Yes. But any recent XL or Plus, or Max named phone I've owned, have all been large phones, and not a one hand device. Only phone that's truly an easy one handed phone would be like the Pixel 5, but I found that too small, and hard to type on, and a bit tiny to see the display well. I gave my Pixel 5 to my son, it is a really cool phone though.
But yes I am comfortable with the 12 Pro Max size, so much screen real estate for YouTube and videos on Reddit and Twitter. Plus like I've said many times, the screen tech in this phone is fantastic, the deep black AMOLED display is just #1 for me, plus it also gets plenty bright outdoors, and easy to see outside in the sun.
Yeah, I'm still a bit miffed on certain iOS stuff, and find stock Android better, but iOS 14.3 is growing on me, meaning I'm getting used to it, or it's limitations and differences compared to what I'm accustomed to.
But the big features most important to me on a smartphone are here in spades;
- Battery life #1
- Bright vibrant display with great black AMOLED screen
