but certainly less conductive in terms of total dissolved salts than the ocean. I meant "fresh" water in the sense of, not ocean water, not something you'd want

- jhugo 5y agoThe phone is IP68, so I would think the conductivity of the water is not a major concern unless there is some mechanical damage that impacts the waterproofing
- walrus01 5y agoThe lightning or USB-c connector on a phone has voltage present, and exposed copper like that plus salt water surely isn't a good combination. Without making an ip68 rated twist lock huge charger connector I don't see how the port itself can be waterproofed.
- jhugo 5y agoThe IP68 rating applies to the entire device, it doesn't exclude the charging port. These connectors are well-protected against complete shorts (e.g. people sticking a piece of metal into the port). Both Lightning and USB-C have protocol negotiation at low-voltage/low-current before any meaningful current will be delivered by either side.
