A whole lot of judgy comments throughout this thread. I've been bringing my phone into the shower for the past 15 years, and quit bagging them since all the flagship handsets were IP67 rated or stronger.
I accept the liability of it, and it has not been a problem for me by and large, and I have no regrets.
I would estimate as much as 5% or 8% of my phone use has been standing there in an enjoyably hot shower and listening to podcasts or puzzling through some idea (building an estimated moving cost to relocate to another market for example, and all its tax implications) or catching up on all the personal correspondence that I had ignored for the day.
If that makes me a monster, at least I'll be an specially clean one.
