The message you’re seeing is a protective feature designed to prevent damage to your iPhone when moisture is detected in the charging port. Even if you can’t see any water, it could still be there, potentially causing a short circuit. Here are a few steps you could take:
1. Disconnect the charger and let it dry: As the alert suggests, unplug your iPhone and give it some time to dry. It could take a few hours or even a day or two depending on how much moisture is present.
2. Try to remove moisture: If you’re in a hurry, you can try to gently blow into the port or use a soft, dry, lint-free cloth to absorb the moisture. Be careful not to insert anything into the port, as you could cause further damage.
3. Avoid charging your device until the moisture alert disappears: Charging your iPhone while the lightning port is wet could cause further damage.
4. Restart your iPhone: In rare cases, the problem could be a software issue. If you’re sure your iPhone is dry but the message is still appearing, you could try restarting your iPhone.
If none of the above steps work and the alert continues to appear, contact Apple Support or take your iPhone to an authorized Apple Service Provider for further help.
Good luck!
