How To Fix Samsung Galaxy Note 9 Shuts Down On Its Own When Battery Level Decreases

Problem: Hi there i have a samsung galaxy note 9 in mint condition the only issue i have is the battery life. For a long time now the battery seems to charge up really fast maybe 1 hour and its full but it never drops past 48% it just shuts off at that point which is really annoying when there is more than half the battery life left and i can’t use the phone. How do i fix this issue i believe Samsung has done something to sabotage this in their updates so it makes you just go out and buy a new phone but im not going to be that fool lol, so let me know if i need to do a factory reset or is there another way to fix this issue thx.

Solution: Before performing any troubleshooting steps on the 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 troubleshooting steps listed below are recommended for this particular problem.

Perform a Soft Reset

One of the first troubleshooting step that you will need to do is a soft reset. This will refresh the phone software and usually fixes minor software glitches.

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

Once the phone starts try to check if the issue still occurs.

Check if the problem occurs in Safe Mode

There are instances when an app you downloaded on your phone can cause issues. To check if a third party app is causing this 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 screen with the device name.
  • 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.
  • Safe mode will display in the bottom left corner of the screen.
  • Release the Volume down key when you see ‘Safe Mode’.

If the issue does not occur in this mode then the problem could be caused by one of the apps you downloaded. Find out what app this is and uninstall it.

Wipe the cache partition of the phone

Your phone will store cached data of apps in a dedicated partition in its internal storage. This data helps apps open faster making for a better mobile experience. There are however instances when this cached data can become corrupted and can cause issues with the device. To check if this is what’s causing the problem you should wipe the cache partition of the phone.

  • Turn off the phone.
  • Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  • When the device logo screen displays, release only 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 several times 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 to consider if the above steps fails to fix the problem is a factory reset. This will revert the phone back to its original factory condition. Make sure to backup your phone data before doing this step.

  • Make sure that the phone is off.
  • Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  • When the device logo screen displays, release only 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 several times key 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 phone has fully started do not install any apps in your phone yet. Try to check first if the battery drains quickly.

In case the issue still occurs after performing the steps listed above then this could already be caused by a faulty hardware component, possibly the battery. The best thing to do right now is to bring the phone to a service center and have it checked.
