Are you seeing the warning “Moisture Detected in Charging Port” on your Samsung phone, even though your phone is completely dry? Don’t worry this is a very common issue on Samsung Galaxy devices.

Many users face this problem after:

• charging overnight
• using the phone in humid weather
• updating software
• connecting a different cable or charger

The good news is, you can fix it safely at home without damaging your phone.

In this guide, you’ll learn why this happens and the best Samsung moisture detected fixes that actually work.

Why Does Samsung Show “Moisture Detected” When Phone Is Not Wet?

Samsung phones have a safety feature to protect the charging port from short circuits. Sometimes the sensor becomes overly sensitive and shows a false alert.

Common reasons include:

• Humidity or temperature change
• Dust, lint, or pocket dirt in the USB port
• Water drops inside cable/charger (not phone)
• Charging immediately after being in a cold/warm environment
• Corroded or dirty USB-C pins
• Software bug after an update
• Damaged charging cable or loose port

Samsung Fix: Moisture Detected in Charging Port but Phone Is Dry

Important:
Do NOT force charge your phone using a wet cable or wet charger. Also avoid using sharp objects inside the charging port.

1. Unplug Charger & Restart the Phone

Sometimes the warning stays even after the port is dry.

Fix:

1. Unplug the charger
2. Restart your phone
3. Wait 2 minutes
4. Try charging again

This simple step fixes temporary system glitches.

2. Clean the Charging Port Safely (Most Effective Fix)

Even if the phone is not wet, dust can trigger the moisture warning.

Fix:

1. Turn OFF the phone (optional but safer)
2. Use a soft brush or dry toothbrush
3. Gently clean the USB-C port
4. Blow air lightly (or use compressed air)

After cleaning, wait 5–10 minutes and test charging.

Avoid:

• pins, needles, metal objects
• pouring water
• using alcohol directly inside the port

3. Dry the Port Using Cool Air (Safe Method)

Even humidity can trigger the sensor.

Fix:

• Keep the phone in a dry room
• Use a fan or cool air from hair dryer (NO HEAT)

If you use a hair dryer:

• Only cool mode
• Don’t use hot air (it can damage the port and battery)

4. Try a Different Cable & Charger

Sometimes your cable or adapter has moisture or damage.

Fix:

• Use an original Samsung cable if possible
• Try another fast charger
• Avoid cheap duplicate cables

Many users fix the problem simply by changing the cable.

5. Charge Using Wireless Charging (Temporary Solution)

If your Samsung supports wireless charging, use it while fixing the port.

Fix:

• Place the phone on a wireless charger
• Let it charge normally
• Meanwhile, keep the charging port dry and clean

This helps you avoid urgent battery problems.

6. Clear USB Cache (If Available)

Some Samsung models store USB-related cache.

Fix:

1. Go to Settings → Apps
2. Tap Filter icon → Show system apps
3. Search: USBSettings
4. Open it → Storage
5. Tap Clear cache
6. Restart phone

If you don’t see USBSettings, skip this step.

7. Turn Off Fast Charging (Sometimes Helps)

Fast charging can trigger the warning if the port connection is unstable.

Fix:

1. Go to Settings
2. Open Battery and device care
3. Tap Battery
4. Go to More battery settings
5. Turn OFF:
   • Fast charging
   • Super fast charging (if available)

Now try charging again.

8. Boot into Safe Mode (Check If App Causing Issue)

If the warning started after installing an app, Safe Mode can help identify the cause.

How to enable Safe Mode:

1. Press and hold Power button
2. Tap and hold Power off
3. Select Safe mode
4. Plug in charger and check

If charging works in Safe Mode, a third-party app may be causing conflicts.

9. Update Samsung Software

Sometimes this is caused by a software bug, and Samsung fixes it in updates.

Fix:

1. Go to Settings → Software update
2. Tap Download and install
3. Install updates and restart

10. Last Working Trick: Turn Off Phone and Charge

If moisture warning blocks charging, try this:

Fix:

1. Power OFF your phone completely
2. Plug in the charger
3. Wait 5–10 minutes

Sometimes the phone charges normally while OFF.

Use this only if you are sure the port is dry and clean.
