How To Fix Samsung Galaxy A9 Does Not Charge When On

Problem: My Samsung galaxy A9 will not charge AT ALL when it is on. I’ve done every process (except for the backing up and factory resetting) and then when its off it will show the bolt with the battery for about 5 seconds and then stop. then it will appear again and this will continuously happen. during the times of when it is showing that bolt icon it is charging. but not good. it takes approximately a full 24 hours for it to charge to full. I have cleaned out my charging port with a plastic corner (it was said not to use anything metal as for a potential to screw up the charging) and I even had it sprayed out with a air canister. but nothing has worked to make it charge normally. note: i do have the original charger that came with it, my google home charger that has worked with it, and one of my friends basic charger that they had. I am clueless as to what to do next, but am waiting to do the factory reset.

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

Clean the charging port of the phone

The first thing you should do in this case is to remove any presence of dirt in the charging port of the phone. Use a can of compressed air to clean the port making sure that any foreign matter is removed.

Try using a different charging cord

The charging cord that comes with your phone can get damaged easily especially if it is constantly coiled or bent. To eliminate the possibility of the problem being caused by a faulty charging cord you should try using a new one.

Try using a different wall charger

Another factor that can cause this problem is a faulty charger. Try  using a new wall charger then check if the issue still occurs.

Try charging the phone from a computer USB port

There are cases when one of the pins of the charging port is not functioning properly. When the pin responsible for fast charging using a wall charger gets damaged you will only be able to charge the phone from a USB port. To check if this is what’s causing the problem check if you can charge the phone from a computer USB port. If the phone charges then you will need to have the charging port of the phone checked and possibly replaced at  service center.

Check if the problem occurs in Safe Mode

One factor that can cause this problem is a third party app which you downloaded to the phone. If you have downloaded an app before experiencing this problem then that app could be the culprit. To check if the problem is caused by an app 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 phone Off
  • Press and hold “Power”
  • At the “Samsung” logo, release “Power” and immediately press and hold “Volume down”
  • After the phone finishes rebooting, release the keys. A “Safe Mode” watermark should be visible in the lower area of the home screen.

If the issue does not occur in this mode then you should find the app that is causing the problem and uninstall it.

Wipe the cache partition of the phone

Sometimes the phone’s cached data can get corrupted and when this happens certain issues can occur on the device. To eliminate this possibility you will have to wipe the cache partition of the phone.

  • Turn the phone Off if necessary
  • Press and hold “Power” “Volume down” and “Home”/”Bixby” at the same time
  • At the Android screen, release the buttons and wait for access to Android Recovery
  • Press “Volume down” to navigate the menu to highlight “Wipe cache partition”
  • Press “Power” to select the highlight
  • Finally, highlight “Reboot system now” and press “Power”

Check if the issue still occurs.

Perform a factory reset

One last troubleshooting step that you should consider doing is a factory reset. This reverts your phone to its original factory condition. Make sure to backup your phone data before doing this step as it will be deleted in the process.

  • 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.

In case the above steps fails to fix the problem then this is most likely caused by a faulty hardware component already. The best thing that you can do right now is to bring the phone to a service center and have it repaired.
