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)
I’d rather have another USB port actually. It’s just so much more versatile.
Occasionally, I’ll use my phone to play a show, with a USB to HDMI. I used to keep a wireless charger next to the TV for that use case.
