iPhone says “Liquid Detected” but it is dry? 7 fixes that work

Since the iPhone XS and XR, iPhones check the charging port for liquid before they start charging. If the pins look wet to the sensor, the iPhone stops charging to protect itself and shows one of these messages:

• Liquid Detected in USB-C Connector (iPhone 15 and later)
• Liquid Detected in Lightning Connector (iPhone 14 and earlier)
• Charging Not Available with an explanation that liquid was found

The alert is there to prevent corrosion. Charging with water in the port can damage the pins on the phone and the cable, which turns a free problem into a repair.

Why does my iPhone say liquid detected when it is not wet?

The sensor does not see water. It measures electricity between the pins, and anything that conducts a little can set it off. That is why the alert often appears on a phone that has not been near a sink:

• Humidity and sweat. A bathroom after a shower, a gym bag, a hot car or a phone in a pocket on a humid day can leave a thin layer of moisture in the port.
• Lint and dirt. Pocket lint packs into the port over months. It holds moisture and can connect pins that should not touch.
• A damp or damaged cable. The alert checks the whole connection. A cable end that got wet, or a cheap cable with bad wiring, can trigger it on a perfectly dry phone.
• Corrosion. Old water exposure can leave a green or dark film on the pins that keeps setting off the sensor.
• Software glitches. Occasionally the alert gets stuck after an update. A restart clears that.

7 fixes for the iPhone liquid detected alert

What is Emergency Override, and should you use it?

When the alert appears while the cable is plugged in, the iPhone may offer an Emergency Override. Choosing it lets the phone charge anyway.

• Use it if you need the phone for an emergency and it is nearly dead, or if you are sure the phone is dry and the alert is a false alarm.
• Avoid it if the phone really got wet in the last day. Charging with water in the port can corrode the pins on both the phone and the cable.

A safer option in most cases is wireless charging, which does not use the port at all.

Charge wirelessly while you wait

Apple confirms that wireless charging still works while the alert is showing. Wipe the back of the iPhone dry, then place it on a Qi, Qi2 or MagSafe charger. If you do not have one, this is a good reason to buy one: it means a wet port never leaves you with a dead phone again.

Did your iPhone actually get wet?

Recent iPhones are water resistant, not waterproof. The rating is tested with fresh water in a lab and wears down over time, especially after drops or a screen or battery repair. Salt water, pool water, soda and coffee are also harder on the phone than clean water.

If the phone went in the pool, the ocean or a drink, rinse the port area briefly with clean fresh water if it was salt water or a sugary drink, then follow our guide on what to do when your phone gets wet. Watch for signs of real damage over the next few days: a foggy camera, speakers that sound muffled, a screen that flickers or a battery that drains fast.

How to stop the alert from coming back

If you see this warning every few weeks, something in your routine is getting moisture or dirt into the port. A few habits make a big difference:

• Do not charge in the bathroom, and leave the phone outside while you shower. Steam is one of the most common causes.
• After the gym or a run, wipe the phone and let it sit for a few minutes before plugging in. Sweat is salty and conducts well.
• Keep the phone in a pocket without lint, or in a case with a port cover if you work outdoors, at the beach or on a construction site.
• Replace frayed or cheap cables. Stick to Apple cables or certified ones.
• Use a wireless charger at night. It keeps the port out of use and saves wear on the connector too.

Android phones have a similar feature. Samsung Galaxy phones, for example, show a “moisture detected” warning and stop cable charging in the same way, and the same fixes apply: dry the port, try another cable, and charge wirelessly in the meantime.

Alert keeps coming back? It may need a repair

If the alert appears with every cable, on a dry phone, after 24 hours, a restart and an update, the port may be corroded or damaged. Book an appointment with Apple or an Apple Authorized Service Provider such as Best Buy.

• Under warranty: Apple's one-year limited warranty does not cover liquid damage. If the port is simply faulty, it is covered.
• With AppleCare+: accidental damage, including liquid, is covered for a service fee, which is much cheaper than paying full price.
• Out of warranty: ask for a diagnosis first. Sometimes a professional port cleaning is all it needs. If the phone is older and has other problems, compare the quote with the value of the phone before you decide.

If the alert goes away but the phone still charges slowly or not at all, the problem is elsewhere. Our guide to an iPhone that will not charge covers the next steps, and a worn battery can make charging behave oddly too. See whether replacing the battery is worth it.
