iPhone Not Charging and USB-C Accessory Draining Battery but nothing is plugged in

My iPhone 16 is not charging when plugged in and it says a USB-C accessory is using the battery all the time (but nothing is plugged in). I tried to go into an Apple Store for support, and I was early. When the store manager started helping me, after starting to run some diagnostics, he said "what the ****" and complained that I was early and said he would be back. He didn't come back after 15 mins, so I left because that was bizarre. Any ideas about what is wrong with my phone or fixes? I obviously don't want to go back to the Apple Store.

You need to have Apple perform diagnostics on your iPhone. It can be done in person at an Apple Retail Store or at an Apple Authorized Service Provider. You can also contact Apple Support and request remote diagnostics.

Let Apple Support do diagnostics and they’ll be able to explain your repair options. Mail-in service is an option they can discuss with you.
