What to do if your Samsung Galaxy S9 takes too long to charge

There are times when your Samsung Galaxy S9 won’t charge but there are also situations wherein it charges but takes too long to reach 100%. There are several reasons why this problem happens but we don’t have to tackle all of them. Instead, we just have to find out how to make your phone charge normally.

In this article, I will guide you on how to troubleshoot your Galaxy S9 that takes too long to charge. We will try to rule out the most common possibilities why the problem occured. I already encountered this problem in the past so I know a thing or two that could help you fix it and I will share that with you. So, continue reading as this guide may be able to help you one way or another.

But before anything else, if you are looking for a solution to a different problem, then visit our Galaxy S9 Help Guides page for we have already solved the most common problems with this device. Odds are that we’ve already published articles that could help you with your concern. So, take time to browse that page and find issues that are similar with yours.

Now, here are the things you need to do if your Galaxy S9 takes a long time to fully-charge its battery…

  1. Force reboot your Galaxy S9 first.
  2. Charge your phone while it’s powered down.
  3. Make sure there are no signs of physical and liquid damage.
  4. Verify that your phone isn’t overheating while plugged in.
  5. Factory reset your Galaxy S9 and try charging it.

First of all, if it’s the first time you encountered this kind of problem, then you should try doing the forced reboot first as it might be just a result of a minor firmware issue. Minor problems can easily be fixed by a normal reboot or forced restart. Press and hold the volume down button and the power key at the same time for 10 seconds or more. Your device will reboot like it normally does but its memory will be refreshed. After that, try to charge your phone and observe if the pace is still slow.

The next thing you should do to know more about the problem is to turn your phone off and then connect it to the charger. If it charges normally or even quick-charging, then it means that the problem is either caused by a firmware issue or some of the apps are causing the problem. There are times when you have bunch of applications running in the background that the phone uses up too much power. In this case, all you gotta do is close all apps running in the background and your phone should charge normally after that. However, if it’s still slow-charging even if it’s powered down, then move on to the next procedure.

Try to check your phone to see if there are signs of physical and/or liquid damage. As the owner, you should be the first one to know if the the phone got dropped on a hard surface or left submerged in water for an hour or more. Physical and liquid damage can cause slow charging especially if the circuits have been messed up but if there are no clear indications, then move on to the next procedure.

Another thing you have to verify is if the phone heats up so bad while it’s plugged in or placed on a wireless charger because if it does, it’s more likely a hardware problem. Smartphones do heat up while charging but not to the point that it would be uncomfortable to touch. Overheating will always result to hardware damage so the moment you notice the phone is heating up so fast, disconnect it from the charger immediately and bring it to the shop.

Assuming that the phone isn’t overheating while being charged, the next thing you should do if you still have enough battery left is to factory reset your device. This will rule out the possibility that the problem is only with the firmware. So, if the problem continues after the reset, then it means you need to visit a technician for it to be fixed. Make sure to backup important files and data before the reset as they will be deleted especially ones that are saved in your phone’s internal storage. Here’s how to reset your Galaxy S9:

  1. Back up data on the internal memory. If you have signed into a Samsung account on the device, you have activated Anti-theft and will need your Samsung credentials to finish the master reset.
  2. Turn off the device.
  3. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  4. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.
