Liquid detected in Lightning Connector: what it means and what to do
“Liquid detected in Lightning Connector” means your iPhone has sensed liquid in its charging port, on the cable or on the accessory, and has blocked charging and accessories until everything is dry. Apple says to unplug, tap the phone with the connector facing down and retry after at least 30 minutes. Full drying can take up to 24 hours.
This page is about the alert itself on iPhone XS, XS Max, XR and later: what each of Apple’s four alert texts means, how long the warning can last, what the emergency override risks and what it means when the phone never got wet. Samsung and Pixel phones are covered in the steps for drying the charging port, and the camera, speaker and screen in drying the whole wet phone.
What “Liquid detected in Lightning Connector” means
“Liquid detected in Lightning Connector” is an iPhone warning that liquid is in the Lightning port or on the cable or accessory plugged into it. To protect the phone and the accessory, charging and accessory connection stay unavailable until the connector, cable ends and accessory are dry. Apple describes the warning for iPhone XS, XS Max, XR and later.
The warning comes in four versions. Apple’s liquid-detection alert page, last updated on October 30, 2024, ties each text to the connector and to what you plugged in:
| Alert text | Connector on the iPhone | When Apple says it appears |
|---|---|---|
| Charging not available | Lightning | You connect the iPhone to a charger and liquid is detected |
| Liquid Detected in USB-C Connector | USB-C | You connect an accessory or charger with a USB-C to USB-A cable and liquid is detected |
| Liquid detected in Lightning Connector | Lightning | You connect a Lightning accessory that doesn’t charge the iPhone and liquid is detected |
| Liquid Detected | USB-C | You connect a USB-C accessory and liquid is detected |
Apple lists the last two as alerts you may see instead of the first two, so the exact wording is a hint about what triggered the check, not a strict rule. The response is the same for all four. None of the texts says the phone is damaged: they report liquid at the connection, and charging through that wet connection is what Apple warns can cause damage.
How long until liquid detected goes away
A liquid detected alert goes away once the connector and the cable are dry. Apple says to try the cable again after at least 30 minutes. If the alert returns, there is still liquid in the connector or under the pins of the cable, and full drying might take up to 24 hours.
Right away: unplug and tap it out
Unplug the cable from the iPhone and from the power adapter or accessory. Tap the iPhone gently against your hand with the connector facing down, then leave it in a dry area with some airflow. Apple rules out external heat, compressed air, a bag of rice and anything pushed into the connector.
After 30 minutes: first retry
Apple's minimum wait before trying a Lightning or USB-C cable or an accessory again. If the alert comes back, unplug and return the phone to moving air.
After 5 hours: cable charging if the whole iPhone got wet
For an iPhone that was exposed to liquid, Apple's water resistance page asks for at least 5 hours before charging with a Lightning or USB-C cable.
Up to 24 hours: fully dry
Apple says you can keep trying throughout the day and that full drying might take up to 24 hours. If the phone has dried but still won't charge, unplug the cable from the adapter and the adapter from the wall, then connect them again.
The 5-hour figure is from Apple’s splash and water resistance page for iPhone 7 and later, updated on July 14, 2026. If the iPhone went into a pool, the sea or a drink rather than catching a splash, the phone dropped in water come before any charging attempt.
Sound won’t shorten the wait, because a tone moves the speaker’s membrane and the connector has nothing that moves — but if the speaker sounds muffled after the same splash, a speaker water eject tone can play while the port dries. Apple notes that water in the port might degrade speaker or microphone performance until it completely evaporates, so if sound is still wrong after a full day, go through the iPhone speaker checks after water.
What happens if you override liquid detection
Overriding liquid detection lets an iPhone charge through a connector it has flagged as wet. Apple offers the option for emergencies, when you reconnect the cable or accessory. The risk is corrosion: charging through a wet connector can corrode the pins on the connector or cable, Apple says, causing permanent damage or connection problems for the iPhone or accessory.
| Way to charge | When Apple allows it | Risk Apple names |
|---|---|---|
| Wait, then retry the cable | After at least 30 minutes, and again through the day | None named; the alert returns while liquid remains |
| Qi-certified wireless charger | While the alert is showing, once the back of the iPhone is dry | None named |
| Emergency override | When you reconnect the cable or accessory in an emergency | Corroded pins on the connector or cable, permanent damage, connection problems |
The override removes the block, not the liquid.
Apple’s own wording is that you shouldn’t charge a wet iPhone, even though an emergency might leave no choice. If a dead battery would cost more than a damaged connector or cable, for example when you need to make a call, the override is there. If a wireless charger is within reach or the phone can wait, both avoid the corrosion risk.
Liquid detected but the phone isn’t wet
A liquid alert on an iPhone that never got wet points to the cable or accessory first and to the phone second. Apple’s alert covers liquid on the cable or accessory as well as in the connector. A cable that no longer seats fully is a separate matter again — a port packed with lint stops the plug short without any liquid involved. For a dry iPhone, Apple’s guidance is a repeat test with different cables.
| What you notice | What Apple says it can mean | What to do |
|---|---|---|
| The alert appears every time with one particular cable or accessory | That cable or accessory might be damaged | Contact the manufacturer of that cable or accessory |
| The alert appears every time with any Apple Lightning or USB-C cable or accessory | The iPhone might need service | Get service from Apple |
| The alert is gone and the phone is dry, but it still won’t charge | Apple names no cause | Unplug the cable from the adapter and the adapter from the wall, then connect them again |
Apple’s alert page gives no other reasons a dry iPhone might show the alert, so the cable swap is the test its guidance supports. Use a cable you know is dry and working, ideally an Apple Lightning or USB-C cable, since that is the case Apple’s service advice is written for. If a different cable clears the alert, Apple’s reading points to the first cable or accessory rather than the phone.
