Problem: Galaxy S9 Plus charging not working properly (charging level won’t move)

Before, I can use my phone while charging for a few minutes such as music and videos and it would still charge. Right now it charges but it would stay on certain percentage. Let’s say, I used it around 48 percentage and then begin charging. For more than 20 to 30 minutes it didn’t budge. Another example is I just used my phone for internet to read all of your advices. That’s like 30 minutes long and nothing happened still. Is this my charger? Or my battery?

Solution: We don’t think this is a charging accessory issue. The most likely cause must be with the phone itself. To fix the problem, follow our suggestions below.

Forced reboot

Refreshing the system is usually effective in fixing simple or temporary bugs. This should be the first troubleshooting step that you must do. To forced reboot your device, follow the steps below:

  • Press and hold the volume down and power keys together for 10 seconds or more.

If successful, your phone may reboot normally. However, if your phone still won’t respond, do it a couple more times or you may try this.

  • Press and hold the volume down button and don’t release it.
  • Then, press and hold the power key while holding down the volume button.
  • Keep both keys held down for 10 seconds or more.

The second procedure is basically the same as with the first only that we’re making sure that you’re pressing the Power key after the Volume Down because doing otherwise won’t give you similar results.

Calibrate the battery

Sometimes, Android may lose track of the actual battery levels. To recalibrate the operating system so that it gets accurate battery level readings, do the following:

  1. Drain the battery completely. This means using your device until it powers down by its own and the battery level reads 0%.
  2. Charge the phone until it reaches 100%. Be sure to use original charging equipment for your device and let it charge up completely. Do not unplug your device for at least two more hours and also don’t use it while charging.
  3. After the elapsed time, unplug your device.
  4. Restart the device.
  5. Use your phone until it completely runs out of power again.
  6. Repeat steps 1-5.

Wipe the cache partition

Sometimes, installing apps or Android updates may corrupt the system cache. To ensure that the device’s system cache is in top shape, be sure clear the cache partition with these steps:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the Android logo displays, release all three keys.
  4. An ‘Installing system update’ message will show for 30 – 60 seconds before the Android system recovery menu options appear.
  5. Press the Volume down key several times to highlight wipe cache partition.
  6. Press Power key to select.
  7. Press the Volume down key to highlight yes, them and press the Power key to select.
  8. When the wipe cache partition is complete, Reboot system now is highlighted.
  9. Press the Power key to restart the device.

Reset all settings

If you’ve changed some settings in your phone and you don’t know how to revert them back to default, then this procedure will come in handy. It also has similar effects as with a reset but none of your files and data will be deleted when it’s done. So, basically, it’s effective in dealing with almost all settings and/or configuration and here’s how it’s done…

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap Settings > General Management > Reset > Reset settings.
  4. If you have set up a PIN, enter it.
  6. The device will restart to perform the reset of settings.

Factory reset

Should none of the troubleshooting steps above won’t work, wipe the phone with factory reset. Here’s how:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. 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).
  4. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  5. Press Power button to select.
  6. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  7. Press Power button to select and start the master reset.
  8. When the master reset is complete, ‘Reboot system now’ is highlighted.
  9. Press the Power key to restart the device.

Get Samsung help

We believe one of the solutions above will help. However, if the problem remains and no software solution works, the cause of the problem must be due to something deeper. We suggest that you contact Samsung so their technician can examine the device and repair it if necessary.
