iPhone 7 WaterProof Ultimate Test
I explain the differences between iP67, iP68, and IP69. And how much liquid abuse they can actually handle. The iPhone 7 has the bare minimum of water protection. I would suggest that you treat it like a normal phone, and that the iP67 protection is a bonus feature... not something you ever rely on. ESPECIALLY if you use your phone daily, and you keep important things on it.
