Solving the Charging Problem on the Galaxy S20: What To Do When Your Device Won’t Charge

The last thing anyone wants to worry about is their smartphone not charging—especially if they’ve invested in the latest flagship model. Samsung’s Galaxy S20 series has been taking the world by storm, but sometimes the devices can fall prey to charging issues. In this blog post, we’ll cover some of the common reasons for why your Galaxy S20 won’t charge, and provide a few solutions for how to fix it.

Power Supply

The most common reason why your Galaxy S20 won’t charge is because you’re using the wrong power supply. The S20 series supports fast charging, so you’ll need to use a power adaptor that is capable of providing up to 25W of power. If you’re using an older power adaptor with a lower wattage, it won’t be able to charge your device as quickly.


Another possible reason why your device won’t charge is because you’re using the wrong cable. Samsung recommends using the USB Type-C cable that comes with the device, as this is specifically designed for the fast charging capabilities of the S20. Some people might try to use an older cable instead, but this can lead to charging issues. It’s also important to check that there are no kinks in the cable or any signs of wear and tear, as this can also affect how quickly your device charges.

It’s also possible that the battery inside your Galaxy S20 has gone bad. This can happen for a variety of reasons, such as overcharging or long periods of inactivity. To check if this is the case, take a look at the battery indicator in the status bar. If it’s indicating that the battery is low, even when it’s plugged in, then it’s likely that the battery has gone bad and needs to be replaced.

Charging Port

If the battery indicator is showing that the battery is charging, then the issue could be with the charging port. This is usually due to dirt, lint, or other debris that can build up in the port and prevent the cable from making a secure connection. To check for this, use a flashlight to take a look inside the port and see if there is any blockage. If so, you can use a cotton swab and some rubbing alcohol to clean it out.

Software Glitch

In some cases, the issue could be due to a software glitch. This can happen when a phone’s software is out of date, or if there are any corrupted files or settings. To check for this, you can try restarting the device or performing a factory reset. This will reset the device back to its factory settings, which could solve any software-related issues.

Third-Party Accessories

It’s also possible that the issue is due to using third-party accessories. If you’re using a power adaptor, cable, or battery that isn’t specifically designed for the Galaxy S20, it could be interfering with the charging process. It’s best to only use officially licensed accessories to ensure that your device is able to charge properly.

In conclusion, there are a few possible reasons why your Galaxy S20 won’t charge. The most common cause is either using the wrong power adapter, cable, or battery, or a software glitch. It’s also possible that the issue is due to a hardware failure, in which case you’ll need to have the device checked out by a repair shop. With these tips, you should be able to get your device charging again in no time.
