I’ve been regularly washing my phone since the X and never had a problem. I also don’t use a case and handle it delicately, but do have glass covers on the front and back.

Use to drop/ break my phones all the time. One day it occurred to be I almost never drop a cup/ glass, so why do I drop my phone? I think I just kind of mental classified it as I did plastic flip phones I grew up with. And once I mentally thought of it an extremely expensive gem containing a super computer, almost never drop it anymore.
