Possibly not related, but my past two Samsungs have had this feature and it drives me crazy. Usually they seem to trigger when using non standard cords and from 0% battery life. This means that I get a very loud warning sound triggering when trying to charge my phone from a battery pack or borrowing someone's cord. Oddly, charging when on (ie not completely dead), this feature doesn't trigger the alarm. I really dislike this feature.

Funnily enough, my Sony Xperia 5 III does this if I plug in a Thunderbolt 4 cable. Charges extra-slowly, and complains about liquid in the USB port. It's probably a not-entirely-compliant USB implementation on the phone.

  Any TB 4 cable or just a specific one?

That means there was a short in the cable

Me too. I switch to wireless charging when this happens and usually I don't get these alarms the day after.

I had my S22 upside down in my pocket and happened to splash water directly into the USB port and nowhere else. The precision was honestly kind of impressive. I only knew about it because my phone freaked out. I let it dry overnight rather than charge it, and everything has been good since then.

  FWIW, you can still charge it wirelessly.

You really dislike a feature that plays a loud sound instead of shorting pins in you USB-C connector together? Guess what is more annoying than a loud sound.

  I think the issue is that it triggers when there is even a tiny piece of dirt in there. Ie. the pins aren't shorted, but there is some damp particle of dust in there causing a 10 Megaohm connection which would do no harm whatsoever. Happens a lot for people who leave USB-C cables in the bottom of bags and they get dirt in the connector (and possibly the residue from that beer that exploded in your bag last year and the sugary water never quite evaporates)

  What?? Those aren’t the only options, the other option is that the device operate correctly…

    I didn't claim there were two options. This function measures the voltage drop between two pins and plays a sound when it is too high. So it is possible: - to just not play a sound, and have it silently switch off the connector (this would feel like a broken cable to you, but at least wouldn't annoy) - that the threshold is not well adjusted. But this is not rocket science, but simple Ohms law stuff, so I doubt this is the problem - you could just not have that protection and live with what happens to the IC inside when those pins are shorted. That could be any number of things, most of them more annoying than a sound Unless you want to change basic laws of physics or the USB-C spec these are the options.

Throw those non-standard cords (and low quality chargers) in the bin. And going to 0% charge is also bad for other reasons like battery longevity.

Hold on... Could this by why I hear a really loud buzzing sound when I connect my laptop to a thunderbolt docking station? The sound only happens for a fraction of a second, and doesn't happen every time; but now that you mention it, it does have the acoustic properties of a warning buzzer! All components genuine AFAIK and supplied by the same vendor, Toshiba/Dynabook; but I wonder if a failing component somewhere causes a bad state that some component detects, triggering this warning sound...

  I doubt it. My guess is that you have speakers/headphones connected to your dock and they're picking up some kind of transients when you plug it in. Capacitors charging can also have some sound, but it's usually quite high pitched. If you're docking station has an external power source, you might find that adding/removing/changing it helps. Or connecting speakers/headphones via a usb DAC.
