Even if you could get all this, the small size and additional internals to bring the phone up to 2019/2020 hardware specs would likely mean a small battery.++++++1
This is exactly it.
Small shouldn't equate with cheap garbage.
I want a small SE sized high end phone. Mostly the screen with no bezels and with Face ID. Thats the whole benefit. You can get the screen of an iPhone 8 on a device the size of an iPhone SE IF you do the iPhone X style screen without a home button.
Would be nice but not essential to have good camera too so its not a step down.
This is the phone I'm waiting for. I either refuse to buy a new phone or will buy used if I have to replace until Apple comes out with a more manageable size.
