How to Fix “Moisture Detected in Charging Port” Error Message

Depending on what type of sensors Samsung puts inside their phones, some of them may be oversensitive. If it detects any dirt particles or anything else, it will detect that as moisture and won’t charge your phone then. Moisture is basically only detected in the USB charging port, not inside the phone hardware or battery area.

Let’s assume that the phone really has some moisture inside the charging port, so we will first look into making this error message go away. There are several tips and tricks you can try at home to get rid of the error message. Some of them listed below are:

  1. Clean the USB charging port
  2. Check cable and charger for any water or liquid on it
  3. Check your phone for water damage
  4. Disable Fast Charging
  5. Force bypass the “Moisture detected” error message
  6. Charge phone in Safe Mode
  7. Charge phone with PC
  8. Reset your phone

We have compiled this list of tips after years of using different Samsung Galaxy Android phones. Over the years, the phones have been through rough use and we have seen all sorts of errors, including this moisture in charging port error.

Alternatively, you can also use the various Samsung secret codes for diagnostics and troubleshooting purposes.

Method 1 – Clean the USB charging port

The first and foremost tip to try is to clean the USB charging port of your phone. It’s too small that you cannot directly clean it with your finger. Here is how you should clean the port:

Clean with tissue paper:

Take a small piece of tissue paper and roll it from one end so it becomes a little pointy and small. Insert and leave the tissue paper inside the port for a minute or two and then gently move it around the port so it absorbs all the water. Repeat this method a couple of times.

Blow into the charging port:

Hold the phone near your mouth and gently blow into the charging port. This will help clean up any dust particles from around the USB connector. A can of compressed air can also do the job.

Rise with distilled water

You can also try to rinse the charging port with distilled water so any dust particles may get washed away. Once done, use a small paper strip to wipe away the rest of the liquid.

Dry the USB port with hair dryer

If there is actually any liquid present in the USB charging port, you can also use a hair dryer to blow mild air to dry it.

Method 2 – Check cable and charger for water

Is your cable around a water or any liquid source? This could be one reason. If your USB cable is wet and you plug it into the phone, you will still get the “Moisture detected in charging port” error on the phone and it will not charge. If your USB cable is even slightly wet, repeat method #1 to clean up your USB charging port and remove the cable.

You should also check your charging adapter for any wetness or liquid contact. Clean it with a soft cloth. Ideally, replace the adapter with a new one.

Check your USB cable from both ends. If you placed it around dust or started using the cable after a long time, it may have some dust particles or dirt inside the connectors. To clean the cable, take a brush, dip in alcohol and gently clean them from both ends. Completely dry out the cable before trying to use it again with your phone.

Alternatively, you can switch your USB cable and adapter with a new one. Or temporarily, switch to a wireless charger (if you phone supports it).

Method 3 – Check your phone for water damage

All manufacturers include special stickers throughout the phone to check for liquid contact. If any liquid comes in contact with the stickers, they change color letting the technician or buyer know whether water has penetrated through or not.

To check this on your Samsung phone, you can simply pull out the SIM tray. Once you pull it out, there will be a white sticker on the phone’s internal side. Now, if liquid has penetrated, the sticker will be red or pink in color. This simple indicator will let you know whether your phone is water damaged or not.

If you find the sticker to be red or pink in color, you should take your phone to a nearest mobile repair center immediately.

Method 4 – Disable Fast Charging

In case your battery is malfunctioning, you can try charging your phone at a lower voltage. You can do this by disabling the fast charging feature to check if that would help fix the moisture detection error.

To disable fast charging, follow these steps:

  • Go to Settings on your phone
  • Navigate to Battery and device care > Battery
  • On this screen, scroll down and tap on “More battery settings
  • Under the Charging section you will see the following 3 options:
    • Fast charging
    • Super fast charging
    • Fast wireless charging
  • Disable all of these options

Once disabled, you should try plugging in your Samsung Galaxy phone to check if it is charging normally like it should or not.

Method 5 – Force bypass the “Moisture detected” error message

After going through all the previous steps: making sure charging port is dry and your phone isn’t water damaged by verifying the sticker, you can go ahead and bypass the “Moisture Detected” warning that might pop-up when you connect a charger.

Simply connect your charger to the device. Now, the pop-up will be displayed. Seeing how the charging stops after the pop-up, simply reboot your phone without disconnecting it from the charger. This way, your phone will charge normally.

Another method to try is completely shutting off the phone and then charging it rather than reboot to avoid the pop-up altogether.

You only have to do this if you’ve already made sure the charger port is clean and dry and that your phone isn’t suffering from liquid damage. We can sort of bypass the warning and allow your phone to fully-charge by doing this.

Method 6 – Charge phone in Safe Mode

Another option users can try out once they have assured that water isn’t actually in the phone, charging via safe mode. To boot your phone into safe mode, power off the device. Next, power on via the power button but as soon as you see the screen turn on, press and hold volume down key until it finishes booting up.

For successful safe mode boot, the phone will display Safe Mode on top of the UI. You can now connect your charger to charge the phone.

Method 7: Charge phone with PC

In case your phone has already run out of battery juice, and you cannot try the above mentioned fixes, there is one more you can experiment with. Instead of using a charging adapter, try connecting the phone to your computer (Windows PC or Mac) using the USB-C cable.

Check if the phone charges properly via a PC. If this works, this clearly means you have a faulty adapter and you will have to buy a new one. To test it thoroughly, charge the phone with your PC for at least 30 minutes before unplugging it.

Method 8 – Reset your phone

As a last resort, resetting your phone — factory reset — might yield a successful outcome. If you have made it this far in the guide without any luck, this will help. To factory reset your phone, you can go to Settings app then Backup and Reset and from there, select factory reset.

If you want to use the recovery method to factory reset, you can do that as well. First, power off your phone. Once it is off, power it on while holding volume up key. Release power and volume up when screen lights up. The phone should now be in recovery. If you don’t see any options show up, press power button. From the options listed, scroll down using volume down key and select “wipe data / factory reset” by pressing power button.
