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)
Having something built in is so much better than needing a dongle. There’s a reason why even Apple brought back ports like hdmi and sd card slot to their Mac book pro line to eliminate even the needing a dongle for some people.
