What this means is that the iPhone 11 is almost completely resistant to dust and dirt and can withstand immersion in water up to 1.5 meters (about five feet) deep for about half an hour. While iPhones are designed to resist dust, dirt and water, they are not completely waterproof and can be damaged if submerged in water. That's why it's essential to be aware of the status of your iPhone, as a small scratch in the wrong place can have different consequences when your iPhone comes into contact with water. However, if your non-waterproof iPhone fell into the water or if your waterproof iPhone was submerged in liquid for a long time, you should follow almost all of the tips mentioned here.

If your iPhone comes into contact with any of these substances, follow the instructions to clean it.
