I cannot stress enough how important charging is to keep the phone going when the battery drains out. Your new Samsung Galaxy S8 is a powerful smartphone but without power, it’s nothing. We’ve started receiving messages from our readers who bought this new device but are already plagued with a not charging issue.
It’s actually very alarming if the phone refuses to charge because it’s a sign of a serious hardware problem that includes the battery. However, we just cannot make hasty generalization because we’ve seen cases wherein a phone refused to charge after experiencing app- and firmware-related issues. We need to troubleshoot to, at least, have an idea what the problem with the phone really is.
In this post, I will walk you through in troubleshooting your new Galaxy S8 that won’t charge. As we all know, there are two ways to charge the phone; wireless and wired charging. I will, however, guide you on how to troubleshoot the wired charging issue since not every owner has a wireless charger, besides if the wireless charging fails, there’s nothing much you can do about it except send the phone to be checked by a technician. So, read on to learn how to troubleshoot your phone.
But before anything else, if you’re currently experiencing different issues with your phone, then I suggest you visit our Samsung Galaxy S8 troubleshooting page for we’ve already started providing support to our readers who own this device. We understand your phone is still brand new and it should work perfectly without a hitch but not even Samsung can guarantee there won’t be any problems. What we do here is provide help to our readers the best we can so if we haven’t published posts about your concern, feel free to contact us by filling up our Android issues questionnaire.
Troubleshooting Samsung Galaxy S8 that’s not charging
As the owner, you should take some time to troubleshoot your phone to know if the problem is just a minor glitch in the system or hardware or if it really needs to be replaced. Don’t worry, we don’t suggest things that can potentially mess up your phone even more and considering the fact that you may have just gotten the device, time is of the essence because usually stores only give a 7-day replacement period for defective phones. So, here’s what you need to do…
Step 1: Make sure you’re using the original charger and USB cable
Your Galaxy S8’s charger has an adaptive fast charging capability and is designed specifically for the model. It is imperative that you charge your phone using its original charger and data cable. At least, it immediately rules out the possibility that the problem is due to a charger problem, although we also need to check the charger for some issues. Don’t worry though, you only need to do physical check.
Try to look into the port of the charger to see if there is some sort of debris, lint or even corrosion that hinders proper contact of the connectors. If there’s none, then check the cable. You have to physically check both ends for things that also block the connectors. If you can’t find any and if the phone still has enough battery left, try to connect your phone to a computer to find out if the computer detects it because if so, the cable is fine and if the phone is charging, then it’s a charger problem. In this case, the only thing that needs to be replaced is the charger and not the phone.
If the phone is not detected by the phone and not charging when connected to it, then move on to the next step.
Step 2: Rule out the possibility that the problem is caused by a glitch or system crash
This step is very important especially if the phone already has a black screen and won’t respond when the power key is hit. When the system crashes, the phone becomes unresponsive and no matter what you do, it won’t respond not even to the charger. However, there’s one method you can do that will bring the phone back to life:
Press and hold the Volume Down and Power buttons together for 7 seconds. Assuming the firmware crashed and there’s enough battery to power everything up, your device should reboot normally and when it does, it may also charge. If, however, the phone is still not charging and won’t power up, the battery may have already been drained. In which case, try to plug the phone in and do then press and hold the Volume Down and power keys again for 7 seconds to see if the phone boots up.
After doing this and the phone is still powered off and won’t charge, then you can do nothing about it anymore. You have to bring it back to the store and have it replaced. If the phone is still powered on, then continue troubleshooting.
Step 3: Boot in safe mode and try charging
You only have to do this step if the phone is still powered on and is able to reboot in safe mode. What this step does is rule out the possibility that the cause of the problem is one or some of the third-party apps you installed. When in safe mode, all of installed apps are temporarily disabled, so if the not charging issue is caused by them, the device should charge properly while in safe mode. This is how you start your phone up in diagnostic state:
- Turn the device off.
- Press and hold the Power key past the model name screen.
- When “SAMSUNG” appears on the screen, release the Power key.
- Immediately after releasing the Power key, press and hold the Volume down key.
- Continue to hold the Volume down key until the device finishes restarting.
- Safe mode will display in the bottom left corner of the screen.
- Release the Volume down key when you see Safe Mode.
Assuming the Galaxy S8 charges while in this mode, then it’s confirmed that the problem is caused by one or some of the third-party apps. Find the culprit and uninstall it but I know it’s easier said than done. It’s just a few days since you started using the phone, you may not have accumulated that much data, so I suggest you backup your important files and data and then reset your phone.
- From the Home screen, swipe up on an empty spot to open the Apps tray.
- Tap Settings > Cloud and accounts.
- Tap Backup and restore.
- If desired, tap Back up my data to move the slider to ON or OFF.
- If desired, tap Restore to move the slider to ON or OFF.
- Tap the back button to the Settings menu and tap General Management > Reset > Factory data reset.
- Tap Reset device.
- If you have screen lock turned on, enter your credentials.
- Tap Continue.
- Tap Delete all.
If, however, the phone isn’t charging even in this mode, then move on to the next step.
Step 3: Power down your device and charge
Let’s assume the phone still has enough battery to power up its components but won’t charge, the next thing you have to do is turn it off and see if it charges that way because if so, you really have to reset it to fix the problem.
However, if the charging icon doesn’t show on the screen and the LED indicator isn’t lighting up, then it’s not charging even if it’s turned off. At this point, it’s confirmed the phone is suffering from a hardware problem and for a brand new phone, there’s no point in continuing your troubleshooting because it shouldn’t be doing this in the first place.
Send or bring the phone back to the store and request a replacement. If you’re still within the grace period, you may receive a brand new unit as replacement.
Step 4: Reset your phone before returning it if possible
This should be done if the phone still has enough power to perform the reset. It’s a necessary procedure to protect your privacy. So, backup your file and data, disable anti-theft feature and go with the reset.
This is how you disable anti-theft…
- From the Home screen, swipe up on an empty spot to open the Apps tray.
- Tap Settings.
- Tap Cloud and accounts.
- Tap Accounts.
- Tap Google.
- Tap on your Google ID email address if multiple accounts are setup. If you have multiple accounts setup, you will need to repeat these steps for each account.
- Tap 3 dot icon.
- Tap Remove account.
- Tap REMOVE ACCOUNT.
And this is how you reset your phone…
- Turn off the device.
- Press and hold the Volume Up key and the Home key, then press and hold the Power key.
- When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
- Press the Volume down key several times to highlight “wipe data / factory reset.
- Press Power button to select.
- Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
- Press Power button to select and start the master reset.
- When the master reset is complete, “Reboot system now” is highlighted.
- Press the Power key to restart the device.
Good luck with your new device.
