Like you, my USB charging port has died on my S23 Ultra after a recent update. I tried all the usual recommended remedial avenues but to no avail. My two year contract expires next month, so I have decided against going through all the data switch over business after a repair, especially as the S25 Ultra will be released shortly. I would also have to pay my insurance excess towards the repair. My device still wireless charges fine, but this takes longer and is not as convenient. I don't blame Samsung for all this though, as these things simply happen. My S23 Ultra has been a great device, and I will have it repaired off contract, and use it as a second phone when I upgrade. I have a repair specialist who I trust thankfully.
