You plug in your iPhone and see "Charging Not Available" or "Liquid Detected in Lightning Connector" or "USB-C Connector." It sounds alarming, but it's a protective feature. Here's what the alert means, what Apple says to do, and what to do if it keeps appearing when your phone is dry.
Key takeaways
- iPhone XS, XR and later can detect liquid in the charging port and pause cable charging to protect the phone.
- Unplug, tap the phone gently with the port facing down, and leave it in a dry spot with some airflow.
- Try again after at least 30 minutes. Drying can take up to 24 hours.
- There's an emergency override, but charging while wet can corrode the pins. Wireless charging is an alternative once the back is dry.
What the alert means
When you connect a Lightning or USB-C cable or accessory to an iPhone XS, XS Max, XR or later, the phone can warn you if there's liquid in the connector. Charging and accessory connection are then paused until the connector, cable ends and accessory are dry. According to Apple, you may see one of these messages:
| Alert | When it appears |
|---|---|
| Charging Not Available | Lightning iPhone connected to a charger, liquid detected |
| Liquid Detected in USB-C Connector | USB-C iPhone connected with a USB-C to USB-A cable or charger |
| Liquid Detected in Lightning Connector | Lightning accessory that doesn't charge the phone |
| Liquid Detected | USB-C accessory connected |
Why it matters
Apple explains that charging while the connector is wet can corrode the pins on the connector or cable, causing permanent damage or connection problems. The alert is a warning, not a diagnosis of damage.
What to do
- Unplug the cable from your iPhone and from the power adapter or accessory.
- Tap your iPhone gently against your hand with the connector facing down to remove excess liquid.
- Leave it in a dry area with some airflow. A fan blowing cool air into the port can help.
- After at least 30 minutes, try charging or connecting the accessory again.
- If the alert returns, there's still liquid in the connector or under the pins of the cable. Keep drying for up to a day, trying again occasionally. Apple says it might take up to 24 hours to fully dry.
- If the phone is dry but still won't charge, unplug the cable from the adapter and the adapter from the wall, then reconnect everything.
What not to do
- Don't dry your iPhone with an external heat source or compressed air.
- Don't insert a cotton swab, paper towel or other object into the connector.
- Don't put your iPhone in a bag of rice. Apple warns that small rice particles can damage the phone. See why you shouldn't put your phone in rice.
Emergency override
iOS may offer an override to charge anyway; only use it in a genuine emergency. If you reconnect the cable, you may see the option to override liquid detection. Using it while the port is wet risks corrosion, so treat it as a last resort, such as needing to make an urgent call.
Charging wirelessly instead
Apple says you can still use a wireless charger. Make sure the back of the iPhone is dry before placing it on a Qi-certified or MagSafe charger. This is the safest way to keep the battery topped up while the port dries.
If the alert appears when nothing is wet
If you see the alert every time you connect a particular cable or accessory, that cable or accessory might be damaged, and Apple suggests contacting its manufacturer. Try a different cable, ideally an Apple or certified one. If the alert appears with every Apple cable, your iPhone may need service.
Other things to check
- Lint or debris in the port can hold moisture. Inspect with a flashlight; a professional can clean it safely.
- Humid environments such as bathrooms can cause condensation. Move somewhere drier and wait.
- Sweat from workouts can trigger the alert, especially if the phone was in a pocket or armband.
Quick troubleshooting table
| Situation | Try this |
|---|---|
| Phone got wet recently | Dry for at least 30 minutes, up to 24 hours |
| Alert only with one cable | Replace that cable or accessory |
| Alert with every cable, phone dry | Contact Apple Support for service |
| Need power now | Use a wireless charger once the back is dry |

Frequently asked questions
What does "Liquid Detected in Lightning Connector" mean?
Your iPhone sensed moisture in the charging port or on the cable and paused charging to prevent corrosion. Unplug and let the port dry.
How long does it take for the liquid detected alert to go away?
Apple suggests trying again after at least 30 minutes. If the alert returns, keep drying the phone in a dry area with airflow for up to a day.
Can I charge my iPhone when it says liquid detected?
iOS offers an emergency override, but charging while wet can corrode the pins and cause permanent damage. A wireless charger is safer once the back is dry.
Why does my iPhone say liquid detected when it isn't wet?
A damaged cable or accessory can trigger it. Try another cable. If every Apple cable triggers the alert, your iPhone may need service.
