How To Fix Samsung Galaxy S9+ Overheating Error When Connected To Charger

Problem: Hi, As soon as a plug the charger to my Samsung S9+, I get a warning to remove the charger as the device is overheating (The device does NOT feel warm or hot). I tried different cables, wall charger and computer as well as turning it off and charging. I still get the warning and it won’t charge. Now it won’t turn on anymore. Any ideas what might cause it and if it can be fixed? I’m not sure about the android version as I can’t check anymore. Many thanks!

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.

Since this overheating error occurs when you connect the phone to its charger let’s try to isolate the wall charger that you are using first by following the steps listed below.

  • Clean the charging port of the phone using a can of compressed air. Make sure to remove any dirt or debris that might be trapped in this port as this could be one factor that is causing the problem.
  • Try using a different charging cord to charge the phone. If the problem no longer occurs then it could be caused by a faulty cord,
  • Try using a different wall charger to eliminate the possibility of the charger causing the problem.
  • Try charging the phone from a computer USB port. If the problem does not occur then it could be caused by a damaged charging port pin.
  • Try charging the phone using a wireless charger. If the problem does not occur then it could be caused by a damaged charging port assembly.

In case the issue still persists even after performing the steps listed above then proceed with the additional steps listed below.

Perform a soft reset

What you will want to do in this case is to refresh the phone software. You can do this by doing a soft reset which is usually performed when a phone is unresponsive but is also recommended in this case.

  • Press and hold the Power and Volume down key for up to 45 seconds.
  • Wait as the device restarts.

Once the phone restarts check if the issue still occurs

Check if the issue occurs in Safe Mode

An app you downloaded in your phone could be causing this problem. To check if this is the case you will need to start the phone in Safe Mode since only the pre-installed apps are allowed to run in this mode.

  • Turn the phone 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’s likely that the problem is caused by an app you downloaded. Find out what app this is and uninstall it.

Wipe the cache partition of the phone

The phone system cached data is used to speed up the access to your phone apps. Sometimes this data can get corrupted which results in issues occurring on the device. To check if a corrupted cached data is causing the problem you will need 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 keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  • Press the Volume down key to highlight “wipe cache partition.”
  • Press the Power key to select.
  • Press the Volume down key to highlight “yes” 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.

Perform a factory reset

One last troubleshooting step you should consider is a factory reset. This will revert your phone back to its original factory condition. Make sure to backup your phone data before doing the reset 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 issue persists even after performing the troubleshooting steps listed above then this is most likely caused by a faulty hardware component. The best thing to do right now is to have the phone repaired at a service center.
