Galaxy Note 8 is not fast charging

A phone not picking up fast charging is a very common problem, especially with the Samsung Galaxy phones. Samsung users have often reported that they do not get the Fast charging notification when the plug in the charging cable. At times we are not paying attention whether we are using original data cable and charger or not. There are many other reasons which can turn off the Fast charging feature of the phone. Here are the few possible solutions to fix a Note 8 that is not Fast charging.

Use original data cable and charger:

  1. Always use OEM data cable and charger to charge the phone.
  2. Using low-quality aftermarket data cable and charger will not fast charge the phone.
  3. Always make sure that the charger is properly plugged into the switch and the cable is properly plugged into the phone.

Fast charging will not work when you are charging your phone in car, using power bank or using your laptop

  1. Fast charging will only work when your original charger is plugged into an electric switch.
  2. The switch must have proper current to make the charger work.
  3. If the current is not appropriate, the charger will refuse to provide Fast charging to the phone.
  4. The current in a car’s charger, from the power bank or from the laptop is not powerful enough to trigger the Fast charging.

If you think that the issue is in the software, try these solutions.

Clear the cache of your phone: To do so, turn off your phone. Now press and hold Volume Up + Bixby + Power key to get into recovery mode. Once you are in recovery, scroll down to highlight Wipe cache partition and wipe it. Try connecting the charger once you have wiped the cache.

Galaxy Note 8 charging slow

First of all, you need to make sure that you are using original data cable and charger just like I mentioned above. After this, you need to check if there is any application that is slowing down the charging time of your phone. To do so, you can boot your phone in safe mode which will disable all the applications. Once you are in safe mode, you can try charging your phone. If it charges in time, it means that there was an application causing the trouble. Now you need to go through your recent installations to identify the culprit. Here’s how to get into the safe mode.

Boot Note 8 into Safe Mode

  1. Turn off your phone completely.
  2. Now turn on the phone. As soon as Samsung logo appears on screen, press the Volume Down key.
  3. Keep the key pressed until the phone shows you home-screen.
  4. As it shows the home-screen, you can find the Safe Mode watermark on the bottom-left corner.
  5. Charge your phone now and check if the issue is gone.

You can also try clearing the cache of the phone to fix it. The method to clear cache is also given above.

Galaxy Note 8 refusing to charge

If your phone is not detecting the charger, these are the few possible solutions you can try.

  1. Check if the wall charger is properly plugged into the switch or not.
  2. Check if the current coming out of the electric switch is as per requirement or not.
  3. Check if the charging cable is fine or not. Using a damaged cable or an aftermarket cable can be a trouble sometimes.
  4. Make sure that there is no smut in the charging port of your phone.
  5. Also ensure that there is no moisture in the charging port.

Moisture detected in charging port issue

I have already done a detailed guide on how to fix the moisture detected in charging port issue on the Galaxy Note 8. Here’s the solution from the guide.

The Cloth Solution

  1. First of all, you should try wiping off the charging port using a towel or any other suitable cloth.
  2. Shake the phone in order to let all the water out and then wipe it off again.
  3. Try looking into the charging port if there’s moisture left inside. If the phone still gives an error, move onto the next fix.

The Vacuum Cleaner Solution

Got a vacuum cleaner? Let’s fix the phone using a vacuum cleaner then. All you have to do is to suck the moisture/water out of all the holes of the phone. Suck the moisture from the speaker holes, the charging port and the headphone jack. Using vacuum cleaner is the safest way to fix the phone.

The Hair Dryer Solution

Take a hair dryer, turn it on. Set it’s temperature to 1 at max. Do not increase the temperature as we only want to dry off the moisture. Blow the air right into the charging port, the headphone jack and the speaker holes in the phone. Use the hair dryer for a few minutes to completely wipe off the moisture. Once done, you can try putting your phone back to charging.

The Qtip Solution

First of all, take a Qtip and try cleaning the charging port of the phone. Check the Qtip if it pulls out any moisture from the port. If the dry Qtip doesn’t work good enough, you can get rubbing alcohol. Dip the Qtip in the rubbing alcohol and then use it to wipe off the charging port. Let it dry for a while and it will most probably fix your phone.

The Tweezer Solution

If you find out that the charging port of your phone is filled up with corrosion because of water, you can use a tweezer to scrape it in order to remove corrosion. This is a tricky and a risky solution. You have to be very careful while scraping the charging port of your phone. Do this one at your own risk.
