Water Damage
Ever since the iPhone 7, all iPhones have been water-resistant. With that said, water can still damage them if the iPhone is exposed for too long. What’s the difference? iPhone 7 or later can resist water splashes, and depending on your iPhone model, it can resist a maximum depth of up to 3 meters (around 9 feet) of water up to 30 minutes.
If you have an older iPhone or exceed the time or depth, you need to act fast. I’m sure you’ve heard of the rice trick before, but that’s actually not the best option because rice can get mushy and enter your iPhone’s lightning port.
The best thing you could do is turn off your iPhone and leave it somewhere where it can dry up fast. Using a blow dryer is a great way to speed up the process; just make sure it’s set to a cold setting. Experts also recommend using silica gel packs that come with new shoes and placing them in an airtight container with your iPhone.
After you’re sure that your iPhone is dry, you can try to turn it back on. If everything goes well, your iPhone should be working perfectly.
