How To Fix Samsung Galaxy Note 9 Only Works When Connected To Charger

Problem: Hi, I have a Samsung Galaxy Note 9 and I have a problem and I’m not sure if it’s with the battery. It started when my phone froze midway between changing screens and wouldn’t shut down or even sleep. I didn’t know how to force shut down the phone so I left it to die. It was getting warm only because it stayed on ’til it died. Since then, I have only been able to use my phone when it’s connected to the charger. It will boot up when off the charge but it will turn off before it gets to the lock screen. If I take the charger out when it’s on, it will turn off shortly after. Sometimes when I try to boot it up off the charge, the LED light will turn on and stay on even when it shuts down. I have reboot a few times or turn it on while charging to turn the LED light off. Any help would be much appreciated.

Solution: Before performing any troubleshooting steps on this phone it’s best to make sure that it is running on the latest software version. If an update is available then I suggest that you download and install it first.

The best way to proceed in this case is to eliminate the possibility of the problem being caused by a software glitch. Follow the troubleshooting steps listed below which are recommended for this particular problem.

Do a soft reset

A soft reset is usually performed to refresh the phone software. This action usually fixes minor software glitches which could cause issues on the phone.

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

Once the phone boots up check if the issue still occurs.

Check if the issue occurs in Safe Mode

There are cases when an app you downloaded will cause issues on the phone when they are installed. To check if an app you downloaded is causing the problem you will have to start the phone in Safe Mode as only the pre-installed apps are allowed to run in this mode.

  • Turn the device off.
  • Press and hold the Power key past the model name screen appearing on the 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.
  • When Safe mode appears in the bottom left corner of the screen, release the Volume down key.

In case the issue does not occur in this mode then it is most likely caused by an app you installed. Find out what app this is and uninstall it.

Wipe the cache partition of the phone

There are cases when the cached data stored in the dedicated partition of the phone can become corrupted. When this happens this this will usually cause certain issues to occur on the phone. To eliminate the possibility that this is what’s causing the problem you will have to wipe the cache partition of the phone from the recovery mode.

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

Check if the issue still occurs.

Perform a factory reset

In case the above steps fails to fix the problem then the best way to deal with this right now is to perform a factory reset. Make sure to backup your phone data before doing the reset.

  • Turn off the phone.
  • Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  • 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).
  • 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.

Check if the issue still occurs. In case it does then this is most likely caused by a faulty hardware component already, possibly a battery that needs to be replaced. The best thing to do right now is to bring the phone to a service center and have it checked.
