Samsung Galaxy S9 and S9 Plus

The new Samsung Galaxy S9 has a very good battery for the most part, but some users have complained that it does not charge fast enough, and that can be very annoying. If you’re in a hurry or rely on your phone a lot, you don’t want to be tethered to your power adapter.

Samsung Galaxy S9 is packed with a lot of features and apps, and it allows you to download as many more apps as you want. However, this also has a direct effect on the battery, making it drain far more quickly than most users expect. It then becomes an issue after using these apps, and you have to wait for hours to charge again.

Because of this issue, I’m sure there are owners of the Samsung Galaxy S9 that would like to know how they can get their Samsung Galaxy S9 battery to charge faster. In this article, I will explain how you can solve the charging issue on your Samsung Galaxy S9.

Reasons for Samsung Galaxy S9 Slow Charging Issue

You could be experiencing a slow charging issue on your Samsung Galaxy S9 because of three hardware reasons, and I will list and explain them below.

  1. The power adapter is damaged or faulty.
  2. The USB cable is no longer working properly.
  3. There is dirt, dust, or debris lodged in the charging port.

Damaged Power Adapter

If the issue is a result of a broken power adapter, you can be certain by checking your device screen. Whenever you plug in your charger, there is always a message that says ‘fast charging is enabled.’ This message notifies you that your power adapter is working properly to quickly charge your Samsung Galaxy S9. If you can’t see the message anytime you plug in your charger, then you should consider replacing the power adapter. If nothing else, replacing the power adapter isn’t going to hurt anything.

Faulty USB cable

To be sure that the issue is with the USB cable, you can use another USB cable from a colleague or friend (so that you will be certain the problem is with the cable) to test if the issue persists. If a different cable solves the issue, then that will let you know know that its time to get a new USB cable. Luckily, they aren’t expensive and can be found on Amazon or in basically every department store or dollar store.

Dirt in the Charging Port

After using your charger for a while, it’s possible that dirt or debris is stuck inside the charging port, blocking the connectors, which is making it difficult for your Samsung Galaxy S9 to charge quickly. You can use a toothpick to clean up the dust. But be careful not to cause permanent damage to the charging port. Inspect it with a flashlight first, be gentle, and work slowly. You don’t want to break anything and you don’t want the toothpick to break off in the charging port.

Slow Charging Software Troubleshooting Method for Galaxy S9

If the charging issue does not stop after checking out all the reasons explained above, then you should consider troubleshooting your Samsung Galaxy S9. There are also three software issues that might be causing the slow charging issue on your Samsung Galaxy S9. I’ll list them and then get into a bit more detail.

  1. Exit all the background apps.
  2. Uninstall all apps, except for pre-loaded apps.
  3. Launch a system dump.

Clearing the Background Apps

There are times when some apps will be running in the background of your Samsung Galaxy S9, and you won’t even know they’re. These apps can, obviously, drain the battery, and they can make your battery charge slowly and also consume your Samsung Galaxy S9’s internal memory. If you think this might be the case, then you should try to exit all apps, including the ones that you are not actively using. Or, you can even restart your phone to start afresh and see if that solves the slow charging issue on your Samsung Galaxy S9.

To Clear the Background apps

  1. Click and hold a space on your Home screen.
  2. Release your finger as soon as the list of recently used apps appears.
  3. Click on the Task Manager.
  4. Click on the option to End All Applications.
  5. Tap on the RAM option.
  6. Delete the RAM. 

Uninstalling the Third Party Apps

It’s possible that the slow charging issue is as a result of a new app that you just downloaded, especially if you aren’t having issues until shortly after you install a new app or an app updates. If that’s the case, then you are lucky, because you won’t need to uninstall all the third party apps on your Samsung Galaxy S9. Instead, you can just uninstall the new app and see if that solves the issue. If the problem persists after uninstalling the new app, however, then you will have to uninstall the rest of the third party apps on your Samsung Galaxy S9.

How to Enter Safe Mode on Samsung Galaxy S9

  1. Restart your Samsung Galaxy S9.
  2. Wait for a few seconds until the Samsung logo appears on the screen.
  3. You can then press and hold the Volume Down key of your Samsung Galaxy S9.
  4. A Safe Mode text will show up, and then you can release the Volume Down key.
  5. Move through the menu to locate Settings, select More, and enter the App menu.
  6. Click on the Downloaded category.
  7. Choose the third party app that you think is causing the issue.
  8. Click on Uninstall.
  9. Click on OK to confirm the process.
  10. After the app has been uninstalled, click and hold the Power key to restart your Galaxy S9.

The last method you can try is the System Dump. The System Dump method will give you a ROM image and allow you to fully restore your Samsung Galaxy S9 back to its initial factory settings. I will explain how you can carry out the System Dump process below to fix the slow charging issue on your Samsung Galaxy S9.

  1. Launch your Dial Pad.
  2. Press the code *#9900# on the pad
  3. Once a new page comes up, move down and click on the Low Battery Dump option.
  4. Click on the Turn On option.
  5. You will need to wait for a few minutes for the process to finish.

If the charging issue persists after you have tried all the tips and methods above, it’s highly possible that your Samsung Galaxy S9 needs a battery replacement.
