A great news that came from the iPhones 7/7 Plus was the water resistance. But there's a catch: Both older and newer devices can completely lose their warranty if Apple finds that the device's internal components have come into contact with water.
And you may be wondering how the Apple team would check if the liquid entered or not on the device without even opening it. Well then: there is an easy way to analyze if the device is still covered under warranty with the internal components intact. So if your iPhone has come in contact with any liquid, don't completely despair. Check below how to see if it was indeed internally damaged and lost or not the factory warranty. 😉
Fell into the water, now what?
If your device has gotten wet for any reason, Apple advises you to dry it with a soft lint-free cloth and leave it to dry in front of a cooler. That's right, cold: Don't use any driers or hot air, or things like cotton swabs or paper towels to dry the Lightning connector and / or headphone jack (present on some models of iPhones).
Also remember not to carry or insert any type of cord (charger or handset) while the handset is still wet.
How to check if liquid has entered the device
All Apple devices manufactured since 2006 have what they call LCI (liquid contact indicators, or liquid contact indicators).
This indicator is usually white or silver and, since the iPhone 5, is in the SIM card tray (carrier chip). If it comes in contact with water or some kind of liquid (and this does not include humidity or temperature changes), the indicator will turn red. To see it better, use a magnifying glass or even a flashlight.
On older models of iPhones (4 / 4s, for example), this indicator is on the 3.5mm audio output and on the 30-pin connector you can check the indicators of all models of iPhones and iPods on this support page. Apple

While today's iPhones are water resistant (which is different from being officially waterproof, as are the latest Apple Watches, for example), it's always wise to be very careful.
Apple recommends not swimming or bathing with iPhone, exposing the device to pressurized or high-speed water (such as in the shower or water sports), not using the phone in a sauna (dry or steam), or submerging the device. iPhone in water intentionally, do not operate iPhone outside the suggested temperature range or extreme humidity, do not drop or subject the iPhone to other impacts, and of course not disassemble it (including removing screws).
Leave these experiences to the YouTubers that test the strength of appliances! 😜
