Liquid detected in Lightning or USB-C connector? What to do

You plug in your phone and get a warning about liquid in the port instead of a charge. It's a safety feature: cable charging is paused until the port is dry (iPhone has an emergency override, covered below). Here is what Apple and Samsung advise.

What the alert means

Apple says the iPhone XS, XS Max, XR and later can detect liquid in the Lightning or USB-C connector, or on the cable or accessory. Charging and accessories stay blocked until the connector, cable ends and accessory are dry, because charging while wet can corrode the pins and cause permanent damage. Samsung blocks charging for the same reason.

Apple lists four versions, depending on what you connect:

  • Charging not available: a Lightning iPhone on a charger.
  • Liquid Detected in USB-C Connector: a charger or accessory on a USB-C to USB-A cable. Apple says to unplug it immediately.
  • Liquid detected in Lightning Connector: a Lightning accessory that doesn't charge the phone.
  • Liquid Detected: a USB-C accessory.

On a Samsung Galaxy, plugging a charger into a wet port triggers a pop-up and an alarm until you unplug. Samsung says phones rated IP68 or higher have a moisture sensor that stops charging and shows a water-drop icon, and that high humidity alone can trigger the icon.

What to do on an iPhone

  1. Unplug the cable at both ends and leave it out until the phone and cable are completely dry.
  2. Tap the liquid out: tap the iPhone gently against your hand, connector facing down.
  3. Give it air: leave it somewhere dry with some airflow. Apple says a fan blowing cool air into the connector might help.
  4. Wait, then try again. Apple's alert page says to try a cable or accessory again “after at least 30 minutes”.
  5. If the alert returns, liquid is still in the connector or under the cable's pins. Apple says full drying can take up to 24 hours, and you can retry during that time.

30 minutes or 5 hours? Apple's general page for a wet iPhone, published in July 2026, says to wait at least 5 hours before charging with a cable. If the phone itself got wet, not just the cable, we'd wait the full 5 hours.

What to do on a Samsung Galaxy

  1. Unplug the charger.
  2. Gently shake the phone 5 to 10 times, port facing down, or wipe it with a dry cloth. Samsung warns that too much force can damage it.
  3. Lay the phone on a cloth in a well-ventilated spot, or use a fan. Samsung says water evaporates from the port in about 1 to 2 hours; for liquids other than fresh water, it says to rinse the phone in fresh water first and dry it with a soft cloth. Samsung UK also suggests switching it off until fully dry, then back on.
  4. If the icon stays once everything is dry, try another cable, avoid charging in a steamy kitchen or bathroom, and clear the USB Settings cache: Settings › Apps › Filter and sort › Show system apps › USB Settings › Storage › Clear cache. Samsung notes that menus vary by model and software version.

What not to do

  • No heat or compressed air. Apple warns against both; Samsung also rules out external heat and allows only a fan or a hair dryer on cool air.
  • Nothing in the port. Apple names cotton swabs and paper towels; Samsung says any object can damage the port.
  • No rice. Apple says small rice particles could damage an iPhone.
  • No charging while wet, and no wet hands on the phone or cables while charging.

Can you still charge it?

In an emergency, Apple lets you override the liquid detection and charge when you reconnect the cable, but still advises against charging a wet iPhone. Treat it as a last resort. Both companies allow wireless charging. Apple says you can still use a wireless charger; for best results, make sure the back of the iPhone is dry before placing it on a Qi-certified charger. Samsung says port moisture doesn't affect wireless charging, but to dry the phone thoroughly first.

When the alert won't go away

  • Dry but not charging: Apple says to unplug the cable from the adapter and the adapter from the wall (if possible), then reconnect.
  • Only with one cable or accessory: if nothing is wet, it might be damaged; contact its maker.
  • With every Apple cable or accessory: the iPhone might need service. On a Galaxy, contact Samsung if the steps fail.

Apple also notes that water resistance can decrease with normal wear, and liquid damage isn't covered under warranty, though consumer law may give you rights.

Water in the speaker is a separate problem

If the sound is muffled after the same splash, water is most likely in the speaker or microphone, a separate issue from the charging port. Apple suggests laying the iPhone speaker side down on a lint-free cloth to see if water drips out. Samsung says speaker vibration during a call can clear moisture from the speaker mesh.

Our free water eject sound works on a similar idea: a low tone played in your browser to vibrate the speaker. The Apple and Samsung guidance above doesn't mention tones. Our guide to getting water out of a phone speaker has the full method.

Speaker Cleaner Liquid Remover plays low tones to push water out of the iPhone speaker grille, with slow, medium and fast modes and a tone generator. Like the browser tool, it does not dry the charging port or clear the liquid alert. It's an iPhone app on the App Store, with no Android version. It needs iOS 15.6 or later and requires a subscription, with a free trial.
