If you try charging the device it will make an alarm which will continue till the charger is disconnected. The device will not charge. The battery will die. This pop-up will be visible till there is no moisture detected. The alert can be caused by many reasons.

Reasons for the alert:

The reasons for this alert could be:

Reason1: If the device has been in contact with water or any other liquid.

Have you dropped your device into the water at the beach or pool?

 If you have, the device was subjected to water. That is, it was dropped into the pool or the sea. There might be some moisture that’s still present inside the device, which causes the alert to pop up.

Reason2: If the device is in a humid environment.

Do you live in a humid country?

If you do, it could be why this is happening. Since there’s already a layer of moisture present in the atmosphere due to the tropical conditions. The moisture can get settled onto your charging port or charger, which may cause this alert to pop up.
