One should be at the bottom one at the top. I understand space on the phone is a premium but a second port would make the phone so much more usable. Wired headphones, flash drives, camera modules, speaker modules, keyboards, even connection to a TV, all could be used while charging. It’s a shame it’s not a thing, USB is extremely versatile port, but you only get one and it’s used for charging half of the time. (I am aware dongles exist)
The biggest pro of two opposing ports: you could always charge your device regardless of orientation. With just a port on the bottom charging while scrolling in the bed is often uncomfortable
This is my biggest problem with my switch! I have to awkwardly hold it when I’m trying to ay laying on the couch or in bed. I hear the Steam Deck has a port on top for charging so it’s already begun!
And most people add a bulky case anyway. Just integrate that shit into the phone!
