Liquid detected!

My favorite feature in the new iPhones is the notification that the device can’t be charged because water might have gotten into it. The reason for the fear is quite simple, the device may simply catch fire, or it may lead to corrosion of the contacts. Let me remind you that for the last iPhone, the ceiling is 20W, the power supply of which is not included. Of course, the iPhone does not have a moisture sensor, there is a pressure sensor, but it is located in a different place, so it will also be quite problematic to determine whether it is wet. How does he do it? Everything is quite ingenious and simple, checking the resistance between the power rails and the ground. If the resistance is too low, a short circuit must be avoided and an alert should be shown.

I forgot to tell you what to do in these cases. Basically, it is recommended to dry the device, but I use wireless charging in this case. She will heat / dry the device and charge it.
