Just how resistant to water are the new 6S's? I try not to use my phone in the rain, I don't use it in the bath or anything, so we're good there, however I got thinking. What about condensation? So on a typical British day, it's raining heavily so I put on my waterproof. I place my 6S in the pocket of my waterproof. I check it occasionally but try not to take it out fully. When I'm in somewhere dry to use my phone, it's damp due to condensation. How resistant are iPhones to that?
