How to troubleshoot Galaxy S9 Plus that won’t charge

First off, if you’re the owner of the phone, you should be the first one to know if the problem occurred after the phone has been exposed to water for a long time. I understand that it has the IP68 certification which makes it dust and water resistant but then again, the phone isn’t totally waterproof. Given the right circumstances, water can still enter your device and mess up the circuits. Likewise, if the device has been dropped on a hard surface and then this problem started, then it might be due to physical damage. Either it’s water or physical damage, you should bring the phone immediately to the shop or back to the stored so that a technician can check it up for you. But assuming the problem started without apparent reason or cause, then you should try troubleshooting it as there’s always a chance that you can fix it on  your own and with all that being said, here’s what I suggest you do about this problem.

  • Perform the Forced Restart procedure – if you’ve been an owner of a phone with a removable battery, you may have tried pulling the battery out when your device froze or stopped working. But since your Galaxy S9 Plus doesn’t have a removable battery, you can’t do that anymore. But the thing is Samsung didn’t take that away, it hard-wired its devices with non-removable batteries to respond to the forced restart when a combination of keys are pressed and held correctly. So, in this case, you just have to press and hold the Volume Down and Power buttons together for 10 seconds or more. If your phone reboots normally after this, then there’s a chance that it would charge again so connect it to its charger.
  • Perform Forced Restart while charging – assuming the first procedure failed to fix the problem, you should connect the phone to its charger regardless whether it responds or not and leave it connected to it for 10 minutes or so. After which, perform the forced restart procedure again but this time while the device is connected to its charger. This procedure is effective when the phone has a black screen or not responding because it could be that the device crashed and ran out of juice. Most of the time, this method will fix the problem but then there’s no guarantee.


So, after this and your phone is still not responding to its charger, you should try the following procedures depending on the situation you’re in.

  • If your phone has a black screen and not responding, try connecting it to a computer using its original cable because maybe the charger itself is busted. If it still won’t charge or even respond to a computer, then it’s a perfect time to bring it to the service center so that a technician can diagnose properly what the problem really is and hopefully fix it.
  • If your phone is still powered on and everything is working properly except charging, then make sure that the charger is working properly and that there’s no break in the cable. You may try to connect your phone to a computer to know how it responds. If it does respond normally to the computer, then the problem could be with the charger.
  • If you badly need to charge your device, you should try using the wireless charger. It doesn’t just replenish the battery, it would also tell you if the problem is with the phone’s wired charging capability or if the wireless charging has also been affected. But regardless whether the phone charges wirelessly or not, you should see a technician so that the issue will be rectified.
  • On the other hand, if the problem started after an update, you must try wiping the cache partition or even doing the master reset before you bring the phone to a technician because if the problem is with the firmware, it should be fixed by one or both of those procedures.
