Water Resistance
The iPhone 7 is also Apple's first water resistant phone. Apple has waterproofed individual connections within the iPhone rather than adorning it with ugly rubber plugs, and is officially calling it splash, dust and water resistant, at IP67. That means you can dip it in water up to one metre deep for up to 30 minutes, and the smartphone should survive. If for whatever reason it suffers water damage, however, it's worth nothing that this isn't covered by Apple's warranty and you'll have to fork out for a replacement/repairs yourself.

We've used the iPhone 7 in a number of wet situations, such as in the rain and answering a call in the shower, as well as outright submerging it, and it has performed quite well with no lasting problems or damage. It is worth noting, however, that the sensitivity of the display is affected when submerged or covered in large water droplets, which makes the phone hard to operate when wet........love this iPhone 7.
