To dry your iPhone, gently tap it against your hand with the Lightning or USB-C connector facing down to remove excess liquid. Leave the device in a dry place with sufficient airflow. Placing the device in front of a fan that blows cool air directly into the Lightning or USB-C connector can make the drying process easier. This can be a bit extreme, but even after following the procedure mentioned above, if the wet iPhone doesn't turn on after 48 hours, then you have to go the extra mile.
Be very careful when using a hair dryer to repair damage caused by iPhone water. Turn on the cold wind setting and keep the dryer in low power mode and gently run it over your phone. You can keep your phone at a distance to make sure that the air it blows doesn't cause any harm. If this causes your phone to heat up, turn off the dryer immediately.
