Despite the fact that the iPhone 11 is IP68 certified and designed for a depth of two meters up to 30 minutes, there are always some miraculous tales where these smartphones survived for much longer. The latest one is how the 6.1-inch model was recovered from the bottom of a lake in British Columbia and continued to work after being submerged for six months.

Chilliwack free divers Clayton Helkenberg and wife Heather told CBC that after they went into the bottom of a lake to look for lost items, they came across an iPhone 11. They also found a flip phone, but that was severely damaged, unfortunately. The iPhone 11, on the other hand, was in exceptional working condition, save for a broken microphone and some speaker issues.
