Why is my iPhone charging cable getting hot (or saying "Liquid Detected in Connector")?
Direct Answer
If your iPhone displays "Liquid Detected in Lightning Connector" or your charging cable feels unusually hot, unplug it immediately. This warning occurs when moisture, trapped pocket lint, or metal corrosion short-circuits the charging port. Do NOT use a hair dryer, compressed air, or rice. Instead, unplug the cable, gently tap your iPhone against your hand with the port facing down to dislodge liquid, and let it dry in a dry room with airflow for 30 to 60 minutes.

Before You Start
- Unplug the charging cable from both the wall outlet and your iPhone right away.
- Do NOT insert cotton swabs, paper towels, or hair dryers into the charging port.
Never put an iPhone in a bag of raw rice. Microscopic rice particles and starch dust lodge inside the charging port and permanently ruin the metal charging pins.
Setup & Practical Testing Recommendations
-
1
Unplug the cable immediately from your phone and wall
If you feel excess heat or see a "Liquid Detected" alert screen, unplug the charging cord right away. Do not attempt to force charging while the port or connector pin is wet.

Tap your iPhone gently against your palm with the port facing down
Hold your iPhone upright with the charging port pointed toward the floor. Gently tap the phone against the palm of your hand to shake out any trapped drops of liquid.

Leave your iPhone in an open, dry room with airflow for 30–60 minutes
Set your phone flat on a dry towel or wooden table in a room with good air circulation (or near an open window or room fan). Wait at least 30 to 60 minutes before plugging it back in.

Shine a light inside the port to check for pocket lint
Once completely dry, use a flashlight to look inside the small charging slot. If you see a gray wad of fuzzy pocket lint, use a dry wooden toothpick (never metal or safety pins) to very gently scoop out the lint.

Test charging with an official Apple or MFi-certified cable
Plug in an official Apple cable or a trusted brand like Anker. Cheap non-certified $2 gas station cables lack internal thermal safety chips and often overheat rapidly.

If You Don't See It / Troubleshooting
If you see an "Emergency Override" button on your screen...
Only tap Emergency Override if you are in a genuine emergency and need phone service immediately AND you know the port is 100% dry. Otherwise, leave it unplugged.
If your cable tip looks dark, scorched, or melted...
Throw the cable away immediately. A scorched pin indicates an electrical short circuit that will ruin any phone you plug into.
Good to Know
- If you need to charge your iPhone right away while the wired port is drying, modern iPhones (iPhone 8 and newer) can safely charge using a wireless MagSafe or Qi charging pad.
- MFi stands for "Made for iPhone"—look for the official MFi badge on cable packaging to ensure overheating protection.
