Troubleshooting a Non-Charging Samsung Galaxy A21 Phone

Are you having issues with your Samsung Galaxy A21 phone not charging? You’re not alone. Every day, plenty of Samsung users experience this common issue affecting their device’s battery life, and it can be frustrating to try and troubleshoot. To give you some help in fixing this issue, we’ve compiled a comprehensive guide to troubleshooting your non-charging Samsung Galaxy A21 phone.

One of the most important steps in troubleshooting non-charging Samsung Galaxy A21 phones is to check the power source. Make sure that the charger is in good condition and that it’s the right type for your device. If it isn’t, it may be the reason why your phone won’t charge. You’ll also want to check any additional cables or USB ports you might use, as they may be faulty or not compatible.

Checking the Battery

The next step in troubleshooting a non-charging Samsung Galaxy A21 phone is to check the battery. Check your device’s battery charge level to ensure that the battery is not completely drained. If it is, you’ll need to plug the device into a power source to charge it.

Clean the Charging Port

If the battery is not completely drained, it’s time to check the charging port. Over time, debris and dust can get jammed in the port, preventing the charger from making contact with the device. To clean out the port, use a dry cloth or cotton swab and carefully wipe out the port. Make sure to be careful when doing so and avoid digging into the port too deeply.

Replace the Battery

In some cases, the issue may not be with the charging port, but with the battery itself. If the battery is damaged, it won’t be able to receive a charge. If this is the case, you’ll need to replace it with a new one. Make sure to get an authentic battery, as knockoff ones often don’t work properly.

Check for Software Updates

Another possible cause for your device’s charging issues could be due to a software issue. To fix this, check for any available software updates for your device. If there are any available, install them and restart your device to see if the charging issue has been resolved.

Factory Reset

If all else fails, a factory reset may be necessary to fix the issue. Keep in mind that doing this means you’ll lose all your data and apps, so make sure to back them up first. Once you’ve finished the reset, your phone should now charge properly.

Perform Hardware Tests

If none of the above solutions worked, then you may have a hardware issue with your Samsung Galaxy A21 phone. To diagnose the problem, you’ll need to perform hardware tests. You can do this by using a competent third-party repair shop or a service center.


Troubleshooting a non-charging Samsung Galaxy A21 phone can be a difficult and time-consuming process, but it’s important to take the steps necessary to ensure your device is working properly.

Remember to back up your data before doing either of these. With this guide, you should now have a better idea of how to troubleshoot your non-charging Samsung Galaxy A21 phone.
