How To Fix Samsung Galaxy A9 Overheats When Charging

Problem: Phone will overheat while charging and halt the charging process then shut down applications and processes such as data and tethering. It will sometimes give very inaccurate battery charge level readings when it sometimes powers off during this as well and it will say the battery is at 0% then jump up to 30%, or higher when it wasn’t even close to dead when this issue occurred. The screen flashes almost always when you are using the phone. This all started at the same timeframe. I’ll do the troubleshooting steps you most awesome kickass people have provided later today. Thank you.

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 an update is available then I suggest that you download and install it first.

The first step you will need to do in this case is to isolate the charger. Clean the charging port of the phone using a can of compressed air then use a different charging cord and wall charger to charge the device. Does the phone still overheat? If it does then this appears to be a hardware related problem already however there’s a possibility that this could be caused by a software glitch. Follow the troubleshooting steps listed below to verify if this is a software related problem.

Perform a soft reset

A soft reset is usually performed when the phone is unresponsive but is also recommended in this case as it will refresh the phone software.

  • Hold the Power button for 3-5 seconds.
  • Tap Power off.
  • When the device has shut down completely, wait approximately one minute. This will help make sure that the cache and temporary files are wiped from the device.

Once the phone has started try to check if the issue still occurs.

Start the phone in Safe Mode

It’s very likely that an app you downloaded is causing this particular problem. The best way to check if this is the case is 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 “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 phone does not overheat while charging in this mode then it could be caused by an app you downloaded. Find out what app this is and uninstall it.

Wipe the cache partition of the phone

The phone will usually store cached data of apps in a special partition of its internal storage. This cached data allows the phone to open apps quickly making for a better mobile experience however there are instances when the saved data can become corrupted which can cause issues on the device. To eliminate this factor you will need 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.

Once the reset is complete do not install any apps in your phone yet. Try to check first if the issue still occurs. In case is does then this is most likely caused by a faulty hardware component. You will have to bring the phone to a service center and have it checked,
