For many Samsung S8 phone users, charging their devices can be a challenge. It is always a frustration when your device stops charging, and it’s even worse when you’re out and about and have no way to complete the essential task of keeping your phone battery alive. If your S8 phone won’t charge, there are a few things you can try that may help you in solving the problem.

Check the USB Cable

The first thing to check is the USB cable that you’re using to charge your Samsung S8 phone. This is likely to be the issue if the cable is damaged in any way. One of the most common problems is a bent or broken tip, as this will stop the connection between the phone and the charger. You may also need to check for any visible damage to the cable itself, as this could prevent it carrying the current necessary for your phone to charge. If you find that the cable is the problem, you can purchase a replacement easily, either from your carrier or from a third-party vendor.

Check the Charger

It’s also important to check that your charger is working correctly. If you have access to a second charger, you can use this to test whether or not the issue lies with the charger itself. If the second charger works, it’s likely that your original charger is at fault. If you are unable to get hold of a second charger, you can also try pressing the power button on the charger to see if it’s working or not. If it is working, the light on the charger should turn on.

Check Another Device

If neither the USB cable nor the charger are to blame, you can check to see if the port on your phone is the cause of the issue. Try to plug the USB cable into another device, such as a laptop or another phone, and see if the charger works. Doing this will also help to identify whether or not the port is the cause of the problem. If you find that the charger is working on another device, you can assume that your phone’s port is the issue.

Check for Any Obstructions

It’s possible that the port itself could be the issue. Over time, lint and dirt can build up in the port, which can cause problems with charging. To check for this, use a cotton bud dipped in alcohol to clean the port. This should clear away any obstructions and allow for a proper connection to be made between the charger and the phone.

Try Software Fixes

If none of the above steps have worked, there could be an issue with the software on your phone. You can attempt to fix the problem by restarting your S8 device, or by using the ‘Safe Mode’ feature. This will run your phone in a stripped-down version of the operating system, allowing you to identify any software issues that may be causing the charging problem.

Reboot the Phone

If the Safe Mode option doesn’t work, a quick reboot of your phone may resolve the issue. To do this, press and hold the Power and Volume Down buttons together until you see the Samsung logo displayed on the screen. This should then restart your device, which should result in the charging problem being resolved.

Reset Your Phone

If none of the above methods have worked, you can try resetting your phone. This will restore the device back to its factory settings, which should resolve any software issues. To do this, go to your phone’s ‘Settings’ menu, select ‘Backup and reset’ and then select ‘Factory data reset’. Be aware that this will erase all the personal data from your phone, so make sure you have backed up any important information before doing this.


If your Samsung S8 phone won’t charge, there are a few steps you can take to try and resolve the issue. The most common causes are a damaged USB cable, a faulty charger and a blocked port. If you have access to a second charger, try using this to check if the original charger is at fault. You can also try cleaning the port with a cotton bud dipped in alcohol, or you can attempt to fix any software issues by restarting or using the ‘Safe Mode’ feature. If none of these methods work, you may need to reset your phone back to its factory settings.

However, if your problem is still unresolved, it may be the sign of a more serious issue with your device. In this case, it is best to contact your manufacturer for advice and support. If you are still within your warranty period, they may be able to replace your device, or repair it for free. In all cases, it’s best to use genuine Samsung accessories to ensure compatibility and performance.
