Answer 1

Water is a very poor conductor and won’t damage electronics but minerals will. Ports are generally safe on the outside because water usually can’t bridge the gaps. For finer pitched components like a chip it certainly can though.
You can easily run your phone submerged in pure distilled water though. Also your PC if you wanted.
