In many cases, water damage will dry up on its own within a few weeks. However, this doesn't mean you should ignore it. If you don't address water damage right away, it can cause mold growth and other problems in your home. If your iPhone or iPad was completely submerged in water for a period of time, there's no guarantee of repair for water damage.
There are a few things you can try, but don't get your hopes up. If your device just got splashed, it's likely that no water got in, but play it safe and follow these steps anyway. Follow the tips mentioned above, and even serious water damage shouldn't leave your phone completely out of play. And if water has damaged the sensitive parts of the phone, we can repair them in the shortest possible time, with original spare parts (if necessary).Also, if you feel that water has penetrated deep into the phone, be sure to minimize movement to get rid of the water.
While Apple doesn't mention water or liquid damage in its standard one-year warranty for the Apple Watch, it does guarantee the Apple Watch Series 2 or later if used according to Apple guidelines (opens in a new tab). By the way, just because your phone has a high IP rating for water resistance doesn't mean that water can't damage it. Water doesn't waste its time circulating on the phone and the damage it causes is never far away. As more and more phones and devices gain ever better water resistance ratings, damage caused by liquids is less and less of a problem. Letting water sit on the phone causes the corrosion of its circuits, coils and resistors due to the minerals in the water.
However, if the phone is not waterproof, water could penetrate and damage sensitive parts of the phone quickly through the headphone jack, USB port, microphone and other holes.
