I’ve always been a little interested in what “water proof” really means when it comes to iPhones.
The iPhone XS, for example, is “Rated IP68 (maximum depth of 2 metres for up to 30 minutes) under IEC standard 60529”… does that mean I can just take it into the swimming pool, creek or even ocean (giving it a good rinse afterwards) so long as I don’t exceed that depth or time underwater?
I have far less concern if you were to stand in the water and take photos dealing with splashes, but if you keep going just under the surface and taking photos of the kids swimming in the pools detrimental to the phone?
We have used iPhones (8, XS and 11 Pro Max) in the pool over the last few years, although I’m always a little hesitant and only ever put them under for very short moments of time. All were bought at launch to give you an idea of age, but none have shown any ill effects.
We do actually have a waterproof camera, a Fujifilm XP10 that we got years ago (2010ish?), so I try to remember to take that when we are planning swimming want underwater shots, the iPhone is more of a improptue water camera… but like I said, I wonder if it could really be a primary.
But back to your questions, a case would make me feel happier, but given the cost of real water proof cases you’re getting mightly close to the cost of a real water proof camera which would give greater depth and features. Plenty are under $250 too making you far less sad if they eventually break in water.
