Apple premium smartphone iPhone X which a had launched last year offers mud and water resistant rating of IP67. The Cupertino giant is offering this feature in its smartphones along with the iPhone 7/7 Plus and iPhone X continues this trend. Curiously, latest flagship apparently has significantly better water resistance capabilities, a lot so, that it may well stand up to being underwater for greater than two weeks discovered by a weekend diver.

YouTuber Dallas who runs the Man + River channel does “river treasure dives” and enjoys returning lost items to their owners. In a video posted over the weekend, he details what he calls “one of my favorite river treasure dives so far.”

After finding a few random items including sunglasses, a 10K ring, and more, Dallas came across a silver iPhone X. He was able to get it to power back on and working and get it back to the owner, Alyssa (he did open up the iPhone and dry it out). She was particularly excited to get her iPhone back as she is a new mom and hadn’t backed up her X that had lots of newborn photos.

Within the video, Dallas is seen to be opening up the iPhone X, utilizing a hair dryer, and inserting the waterlogged iPhone X in a container filled with silica gel. After three days of drying out, he plugged within the smartphone and let it cost usually.

Technically, an IP67 rating gives iPhone X a water resistance rating of 30 minutes at 1m (about 3 feet) of depth. While it’s great that the device withstood being submerged much longer than rated, it’s important to note that Apple’s warranty doesn’t cover water damage.
