iPhone 7 apparently outlasts the Galaxy S7 when submerged in deep water99+
EverythingApplePro shows the two devices submerged at different depths for set lengths of time. Incredibly, both models managed to survive at 5, 10, 15, 20 and 30ft for five minutes each without any kind of internal leakage. Finally, at 35 feet, the Galaxy S7 apparently succumbed, though the efforts of both will surely instil confidence in owners of either handset.The measured test by YouTuber
It's certainly interesting that the iPhone's supposedly weaker defenses held firm where the Galaxy S7 couldn't hold. However, although the test seems legitimate, one has to acknowledge the fact that such an experiment could easily have been rigged.
The takeaway here is that irrespective of whether your device is IP67 or IP68 — most handsets with an IP rating are one of the two — it's not completely infallible. That said, though not recommended, you could probably get away with deeper submersion for longer than the ratings suggest. It pays to still proceed with caution, of course, particularly since water damage is generally not covered by standard manufacturer warranty regardless of IP rating.
