"Liquid detected in Lightning connector" or USB-C: what it means and how to fix it
Short answer
The alert means your iPhone has detected moisture in its charging port (or on the cable), and it has stopped cable charging to prevent corrosion. Unplug, tap the phone gently with the port facing down, and leave it in a dry place with airflow. Try again after at least 30 minutes; full drying can take up to 24 hours. Charge wirelessly in the meantime. The port's alert doesn't affect the speaker — if sound is muffled too, clear it with a 165 Hz water eject sound.
Since the iPhone XS and XR, iPhones can sense liquid in the charging connector. When they do, you get one of two alerts: "Charging Not Available — Liquid has been detected in the Lightning connector" on Lightning models, or the same message for the USB-C connector on iPhone 15 and later. It's a protective feature, not a fault: charging through a wet port can corrode the pins on the phone and on the cable.
How to fix the liquid detected alert, step by step
- Unplug the cable or accessory from the phone right away.
- Tap the iPhone gently against your hand with the connector facing down to shake out excess liquid. This is Apple's own recommendation.
- Leave it in a dry area with some airflow. A table near a fan on a cool setting is ideal.
- Wait at least 30 minutes, then try charging or connecting the accessory again.
- If the alert comes back, there's still liquid in the port or under the cable's pins. Keep it in airflow and retry periodically — it can take up to 24 hours.
What not to do
- No heat — no hair dryer on hot, no radiator. Heat can damage the seals.
- No compressed air — it can push water deeper.
- Nothing inside the port — no cotton swabs or paper towel.
- No rice — Apple warns rice particles can damage the iPhone. More in does rice dry a wet phone?
Should you use Emergency Override?
The alert offers an Emergency Override option that lets you charge anyway. Use it only if you genuinely need power for an emergency and have no alternative — charging with liquid in the port is exactly the corrosion risk the alert exists to prevent. A wireless (Qi or MagSafe) charger is the safe way to top up while the port dries, as long as the back of the phone is dry.
"Liquid detected" but my iPhone isn't wet
This is one of the most searched versions of the problem. If the phone genuinely hasn't been near water, work through these in order:
- Try a different cable. The alert can be triggered by moisture on the cable's plug rather than in the phone.
- Think about humidity. A steamy bathroom, a humid gym bag, or moving from a cold car into a warm room can leave condensation in the port.
- Check for lint. Pocket lint packed into the port can hold moisture. Shine a light in; if you see debris, have it cleaned professionally or very gently with a non-metal tool — never with a SIM pin.
- Restart the iPhone and try again after it has sat in dry air for a while.
- Test with an accessory you trust. If the alert appears with every cable and accessory for days in dry conditions, contact Apple Support — the port itself may need attention.
The alert and your speaker are separate problems
The connector alert only concerns the charging port. If the phone got wet enough to trigger it, the speaker at the bottom — right next to the port — often has water in its grille too, which makes sound quiet or muffled. That part you don't have to wait out: a pulsed 165 Hz tone pushes droplets out in under a minute. Use the iPhone speaker cleaner with the speaker facing down, or install the Water Eject shortcut for next time.

Quick reference
| Situation | What to do |
|---|---|
| Phone just got wet | Unplug, tap port-down, airflow, wait 30+ minutes |
| Alert keeps coming back | Keep drying; allow up to 24 hours |
| Need to charge now | Wireless charger with the back dry |
| Phone was never wet | Try another cable, consider humidity, check for lint, restart |
| Speaker also muffled | 165 Hz water eject cycle, speaker down |
Frequently asked questions
How long does "liquid detected" take to go away?
Usually 30 minutes to a few hours in dry air with some airflow. Apple says it can take up to 24 hours for the connector to dry completely.
Can I charge my iPhone when it says liquid detected?
Not safely with a cable. Wait for the port to dry, or use a wireless charger once the back of the phone is dry. Emergency Override exists but risks corroding the connector.
Why does my iPhone say liquid detected when it's not wet?
Common causes are moisture on the cable rather than the phone, humidity or condensation, and lint in the port holding moisture. Try another cable, let the phone sit in dry air, and restart it. If it persists for days, contact Apple Support.
Will a water eject sound fix the liquid detected alert?
Not directly — the sound clears the speaker grille, not the charging port. It's still worth running if the speaker sounds muffled, because the speaker sits right next to the port and usually gets wet at the same time.
Which iPhones have liquid detection?
iPhone XS, XS Max, XR and later models can detect liquid in the Lightning or USB-C connector.
