The iPhone 6s Is Not Waterproof
There are videos making the rounds showing an iPhone 6s soaking in a bowl of water and then coming out seemingly unscathed. While the new iPhones appear to be more water-resistant than prior models, don’t bring your new iPhone into the shower. Even if problems don’t manifest immediately, they can appear days later, and a dive into a pool still appears to kill an iPhone 6s.
I dropped my iPhone 5 into water for 1 or 2 seconds, switched it off right away, and dried it for a week. When I switched on again (after that week) it worked fine. However, problems started about 4 months later, almost certainly from that quick rinse, when my screen started to freeze. Apparently, the water initiated some slow corrosion process...
