Find me a decent Android phone with a screen around 5" and I will!
Xperia 5 is a bit bigger but still managable IMO. I suggest using https://www.kimovil.com/ to compare smartphones. Using it I was able to find smaller phones with long battery life which were my two main requirements. I wouldn't use an iPhone again. My last iPhone was an iPhone 4S. Not missing anything.
As far as I can tell, the only Android phones on that that have <5" screens and released in the last 18 months don't even support 5G. iPhone remains the only option :(
