I have also had my phone's USB-C port spontaneously self-destruct, effectively ruining the phone. As you say, burning smells and melted plastic, and I shudder to think if I hadn't been there to power it off and yank the battery. And just this past weekend, a close friend of mine had their Galaxy S6 drain completely to 0 in a minute or two, and then claim water damage in the boot screen (which tests resistance across the port). The phone wasn't wet. Both times, the phone wasn't even plugged in. I am beginning to look very askance at USB-C ports.
