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)
There arw usb-c/heasphone-jack Y-cables so you can charge while listening to music without going for a full blown usb-c hub
All the ones I’ve tried have noise when charging and having headphones plugged in. It’s like a high frequency whine. Would appreciate a suggestion if you have one.
Grow old enough to where you can’t hear the high frequencies
I just bought https://www.amazon.de/gp/product/B09PHMS83L/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 and it’s working fine for me. Might be about the combination of all components though (phone, charger, cable, headphones)?
Did you try different chargers as well?
