When you connect a Lightning or USB-C cable or an accessory to your iPhone XS, iPhone XS Max, iPhone XR, or later, your iPhone can warn you if there’s liquid in the connector.
If you see one of these alerts, your iPhone has detected liquid in the Lightning or USB-C connector or on the cable or accessory. To protect your iPhone and the accessory, charging and accessory connection are unavailable until the connector, cable ends, and the accessory are dry.
It goes on:
Here are a few things not to do:
- Don’t dry your iPhone using an external heat source or compressed air.
- Don’t insert a foreign object, such as a cotton swab or a paper towel, into the connector.
- Don’t put your iPhone in a bag of rice. Doing so could allow small particles of rice to damage your iPhone.
