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)
To give more details since somebody else gave you the short answer: Not only is it possible, most mid-to-high-end phones and all watches have that feature today. Google “Qi charging”, which is the modern global standard (although many devices are still on their own incompatible standards – Galaxy Watch, I’m looking in your direction).
