Apple informed Millions of iPhone customers of a pop-up notification that occurs when water is found in the device’s charging port. If you will Ignore the notification it will cause the pins on the Lightning port or the cable to corrode, and the result will be permanent damage or connectivity issues.
Two types of notifications you’ll find there, that will have a yellow warning triangle and a blue water drop inside.
The first message informs you that “Charging Not Available,” while the second message informs you that “Liquid Detected in Lightning Connector.” Except in extreme cases, it is critical not to ignore both notifications.
If you want to dry your iPhone Apple has some suggestions, such as lightly tapping it with the Lightning connector facing down to remove any excess liquid and placing it in a dry place with adequate airflow, and waiting about 30 minutes before charging it again.
If that notification appears again on the screen, that means that there is still liquid present, so you have to leave the iPhone in a dry place with some airflow for up to a day before charging or connecting a Lightning accessory.
Apple warns against using external heat sources or compressed air to dry out the iPhone and discourages inserting foreign objects into the Lightning port, such as cotton swabs or paper towels.
It is also advised not to put the iPhone in a bag of rice because this can cause damage to the device.
