Is your Galaxy S21 series smartphone not charging?

There’s nothing new to say that the Galaxy S21 lineup doesn’t offer an in-box charger. Therefore, in order to make the most out of it, you’ll need the best fast charger for your Galaxy S21 smartphone. However, using an out-of-the-box third-party charger can cause several charging issues like where the Galaxy S21 won’t charge at all. Other scenarios include where the Galaxy S21 Plus or S21 Ultra will overheat while charging. 

We know it’s frustrating, and decided to come up with our guide on how to fix the Galaxy S21/S21 Plus and S21 Ultra not charging problems. We urge you to try all the methods below to find out whether problems are related to software or hardware. So, let’s get going.  

Note: All the listed troubleshooting methods work well with every smartphone under the Galaxy S21 lineup (S21, S21 Plus, and S21 Ultra).

How to Fix Galaxy S21 Not Charging Problem?

1. Force restart the device

Before you move ahead with any method to fix the Galaxy S21 not charging problem, you should remember, sometimes buggy firmware can cause charging problems on the Galaxy S21 phones. To fix this, you can force restart your Galaxy S21/S21 Plus. It is one of the easiest ways of dealing with charging problems on any smartphone. Restarting a device refreshes the whole system and reloads every running app in the memory. 

Here’s how to force restart your Galaxy S21:

  • Press and hold the Volume Down and Power button at the same time.
  • Hold it until you see the logo 
  • Release the buttons once the logo appears
  • Wait until the device reboots

Most of the time, force reboot is effective when the Galaxy S21 Ultra is not charging. Just in case it didn’t fix the problem, make sure to try the other methods below. 

2. Turn OFF the phone and charge

Here’s another effective way of fixing the S21 not charging problem. It is a simple method where you need to plug in the device to the charger by turning it OFF. This method is also effective in solving any 3rd party app glitches or firmware issues that can hinder the charging process. 

3. Inspect the charging cable and adapter

In case your Galaxy S21/S21 Plus are still not charging after trying out the above methods we recommend you to check the charging peripherals. First, check the compatibility of the power adapter as well as the charging cable. It is best to use the official 25W charger from Samsung or a reliable fast charger. Remember, cheap options are not always good. So, before buying a third-party charger, make sure to read our roundup on the best fast chargers for Galaxy S21,S21 Plus and S21 Ultra

Also, you should check for any breakage or exposed wires in the charging cable. It is because internal damage is the potential reason why the S21 is not charging properly. To ensure this, you can charge another Type-C port device with the same cable and power adapter. If the other devices are charging, then there’s something wrong with your phone and not the cable. In contrast, if you’re looking to change faulty accessories, check our article on the best accessories for Galaxy S21.

4. Check the charging port of Galaxy S21

Now that you know charging accessories are working fine, it’s time to check the charging port of your smartphone. A faulty charging port can cause charging as well as overheating problems on the Galaxy S21 smartphones. First of all, check whether the charging connector connects properly with the port or not. It is possible that dust and debris might block the way of the connector causing the charging issues. You can clean the dirt with the help of a normal old toothbrush. Also, make sure that you don’t insert any pointed objects inside the charging port. 

Now, after cleaning the port, check if the Galaxy S21 is charging or not? If it charges, that’s good, if not move onto the next steps. This method is also useful for ruling outGalaxy S21/S21 Ultra charging port issues. 

5. Give it a try with a wireless charger

Here’s another trick to try when the Galaxy S21 stops charging. Since the S21 series supports wireless charging, you can try charging it via a wireless charger. Even though it is not a permanent fix, you can check if the S21 battery is holding the charge through a wireless charger. If it is charging via a wireless charger and draining at the usual speed, then this means the battery is healthy and can hold a charge. Therefore, if your Galaxy S21 Plus won’t charge when plugged in, it could be due to a 3rd party app or problem with the Type-C port. 

Don’t worry if your phone is not charging as fast as a wired charger. It is how wireless charging works, slow and steady. Just in case the wireless charger didn’t help to charge your phone, switch to the next methods to fix Samsung S21 not charging issues.

6. Is your S21 Phone Wet? Try charging after drying

A wet phone could be another reason why your Galaxy S21 charging port is not working. Even though S21 comes with an IP68 waterproof rating, this doesn’t mean that the phone is fully waterproof and can cause several Galaxy S21 Ultra charging port issues. When the phone comes in contact with water, you’ll see a moisture detected warning on the screen. In that case, you should keep the Galaxy S21 in a cool and dry place for at least a few hours to air dry. Remember, you shouldn’t plug in the charger until it’s completely dry. 

7. Check for software updates

In most cases, S21 charging problems are related to faulty hardware like chargers or dirty ports, but sometimes third-party apps can also do some real damage.
