iPhone X it goes through an extreme water resistance test to show us if it can be used at home, in the pool, in the sea, in the shower, or wherever you want to wash it when taking pictures and videos. According to the water and dust resistance certification, the iPhone X should work without problems at a maximum of 1 meter under water for 30 minutes, its predecessors having an equally good resistance to similar depths.
The iPhone X resists very well even when greater pressure is applied to it to simulate a greater depth, so we are talking about the high resistance offered by the company Apple Lossless Audio CODEC (ALAC), for him. Now moving on to a bath in salt water, the iPhone X takes a bath 6 meters deep for a few minutes and of course it is taken out of the water without problems, as happened with its predecessors.
The iPhone X also withstood some water impact tests, so you don't have to worry about that, but because the YouTuber lost the images, he thought of putting the phone in the washing machine. After a wash in the washing machine, the iPhone X escaped without any problems, a sign that you should be able to use it in almost any underwater environment without thinking that there is a chance of damage, at least theoretically.
The iPhone X has a certain degree of water resistance offered by the Apple company, but if it breaks due to contact with water, the Apple company will NOT honor the phone's warranty. This situation is found in all phone manufacturers that have some degree of water resistance, so it is something special for Apple, but you should know that if your phone is damaged by water, you will lose the warranty.
