Method #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.

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. 

Method #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.

When the phone comes in contact with water, you’ll see a moisture detected warning on the screen.
