Asked at the counter: “My iPhone says ‘Liquid Detected in Lightning Connector’ and won’t charge. It hasn’t been anywhere near water. Do I need a repair?”
Usually not. This alert is a safety feature and it clears on its own once the connector is dry. Here is what Apple says to do, and what not to do.
The alert appears when the phone senses moisture in the connector. Rain, a steamy bathroom, a sweaty pocket or a gym bag is enough. Charging through it can corrode the pins, which is why the phone refuses.
FREE, ONE-MINUTE CHECKS
• Unplug the cable from the phone and from the adapter, and do not plug it back in until both are dry. Apple’s wording: “Don’t plug the cable in again until your iPhone and the cable are completely dry.”
• Hold the phone with the connector facing down and tap it gently against your hand to shake out any drops.
SIMPLE THINGS TO TRY AT HOME
• Leave the phone somewhere dry with some airflow, connector down, for at least 30 minutes, then try again. If the alert is still there, give it up to 24 hours. That is Apple’s guidance, not ours.
• If you have a wireless charger and the back of the phone is dry, you can charge that way while you wait.
DO NOT
• Do not use a hairdryer, radiator or any heat, and do not use compressed air.
• Do not push a cotton bud, paper towel or anything else into the connector.
• Do not put the phone in rice. Apple specifically warns that rice particles can damage the phone.
WHEN IT PROBABLY NEEDS A REPAIR BUSINESS
• The alert stays for more than a day in a dry room with nothing plugged in.
• The phone was properly submerged (a sink, a bath, the sea) rather than splashed. Sea water in particular corrodes quickly; the sooner a technician opens it and cleans it, the better the odds.
• The port has visible green or white deposits on the pins.
If it does need looking at, tell the business honestly what happened and when. It changes what they check first.
