LIQUID DETECTED Charging is not available because liquid has been detected in the Lightning connector. Disconnect to allow the connector to dry.

When you connect a Lightning 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 Lightning port. If you see a liquid-detection alert on your iPhone, read this support article for what to do --> If you see a liquid-detection alert on your iPhone - Apple Support
