Radical test shows Apple lowballed the record iPhone 11 Pro water resistance

While they still carry an IP68 water-resistance certification, Apple doubled down on the depth you can submerge the iPhone 11 Pro and Pro Max to, going from spending half an hour at 2m, to surviving as deep as 4m (13 feet). 

That's a lot tighter sealing and copious adhesive application, though something tells us that the previous iPhone models could have survived such depth, too, just without Apple's guarantee. The poor iPhone 11 still stays rated for 2m depth and shouts something about discrimination, though.

What better way to test the new (and old) certification than to actually take the iPhone 11 and 11 Pro on an underwater drone ride at much deeper dives than Apple's warranty allows. Thus, they were both tied to a Trident drone and dunked in Monterey Bay. 

Needless to say, the iPhone 11 Pro survived Apple's 4m rating for 30 minutes and things worked after that. The kicker, however, is that the iPhone 11 also made it, and only the speaker sounded somewhat more muffled than the one on the more expensive sibling.

You won't believe what followed!

With this bait-y heading out of the way, we'd have to say that submerging both iPhones to double and triple the depths that Apple rates them for is not for the faint of heart, but the Trident did it. Surprise, surprise, the iPhone 11 Pro and even the iPhone 11 managed to work even after spending half an hour at 12 meters (39 feet), save for the aforementioned speaker muffling, and even that was gone in a few days when they dried out completely. 

Was there rice involved? History is silent on that one, but evidently, just as with most water-resistance rated handsets, the new iPhones can survive at much larger depths than they are rated for. Long term damage, though? We'd have to get back to you on that:

Only fools would dare to let their phones stay under water for a long time. Its just water resistance not proof. I use mine during swimming in the pool, beaches, river, lake and waterfalls but never dare to submerge unless it has a waterproof case.

You don't swim with your phone in your pocket? How am I supposed to check my insta when I'm swimming?

This water resistance or water proofing is made to avoid accidental damage to sunken phones, not to dip the phone like it's a sponge.

Problem with all phones is they flex and to a lesser degree are subject to expansion and contraction, which both eventually degrade the seals.

I don't put my iPhone, or my Note in any water at all. Went jet skiing in Laughlin Nevada for my anniversary in September, my phones were in waterproof cases. I'm not taking any chances, with these expensive, important, and impressive devices I carry. No way! Glad to hear the 11 is super tough, but I'd never find out, as long as what I'm in doesn't capsize. Kudos on the water resistance Apple.

Use the device for a few months experiencing the usual wear and tear, dings, bumps, temperature fluctuations and micro flexing in our pockets then repeat the test. The adhesive alone breaks down. People just can’t understand that it’s simply a bit of resistance in-case of an accident not something to go deep sea exploring with.
