How to fix Galaxy Note9 wireless charging not working issue

Are you having wireless charging trouble with your Galaxy Note9? Learn how to deal with it below.

Galaxy Note9 wireless charging stopped working

Not many Galaxy users use wireless charging a lot but if you are the one who finds it indispensable, then you should consider finding solutions if your device won’t charge wirelessly. Below are the troubleshooting steps that you can follow in this situation.

Forced reboot

To check if the problem is due to a temporary bug, you can try to simulate the effects of a “battery pull.” Doing this solution is often effective in fixing minor bugs that developed after letting a device run for some time. If you haven’t tried it yet, follow the steps below on how to do it:

  1. Press and hold the Power + Volume Down buttons for approximately 10 seconds or until the device power cycles. Allow several seconds for the Maintenance Boot Mode screen to appear.
  2. From the Maintenance Boot Mode screen, select Normal Boot. You can use the volume buttons to cycle through the available options and the lower left button (below the volume buttons) to select. Wait for up to 90 seconds for the reset to complete.

Verify charging accessories are working

If nothing happens after rebooting the device, the next step is to ensure that it’s not an accessory issue. You can do that by using another known working wireless charger. If possible, use an official Samsung charger, or a third party one that’s certified by Samsung for a Note9. Not all wireless chargers are compatible with your Note9. If you can’t buy a new wireless charger or find one to use, try to visit your local retail store or Samsung store. Once in there, try to see if you can “borrow” their wireless charging dock. If your Note9 charges fine, that means you have an accessory issue. Otherwise, continue with the rest of the troubleshooting below.

Wipe cache partition

Android uses a set of temporary files called cache to load apps quickly. In some situations, this cache may get outdated, corrupted, or buggy. To ensure that there’s no issues from the system cache whatsoever, you can try to clear the cache partition. This will erase the current system cache to force the device to create a new one. Here’s how it’s done:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. 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).
  4. Press the Volume down key several times to highlight ‘wipe cache partition’.
  5. Press Power button to select.
  6. Press the Volume down key until ‘yes’ is highlighted and press the Power button.
  7. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  8. Press the Power key to restart the device.

Install updates

Some Android problems can only be fixed by rewriting codes associated with them. To ensure that you lessen the chance of problems from developing, or to fix known problems, you want to install system updates as they become available.

Check for bad app

Some apps may become problematic and lead to bugs. To check if you’ve installed a buggy app, you can restart your Note9 to safe mode and observe. Here are the steps to run your device to safe mode:

  1. Turn the device off.
  2. Press and hold the Power key past the model name screen.
  3. When “SAMSUNG” appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see Safe Mode.

While on safe mode, all third party or downloaded applications are suspended. You won’t be able to use them as they can’t run. So, if your Galaxy Note9 charges fine using your charging dock, that means one of the apps is the culprit. To identify which of your apps is causing the trouble, you should boot the phone back to safe mode and follow these steps:

  1. Boot to safe mode.
  2. Check for the problem.
  3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
  4. After you uninstall an app, restart the phone to normal mode and check for the problem.
  5. If your Note9 is still problematic, repeat steps 1-4.

Reset app preferences

Resetting app preferences is oftentimes overlooked in many Android troubleshooting articles but when it comes to an issue like yours, it might help a lot. It’s possible that one or some of your default apps may not be set correctly, causing this glitch to occur. Because there’s no way to know if this guess is true, what you need to do is to simply ensure that all default apps are turned on. Here’s how to do that:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap on More settings at the upper right (three-dot icon).
  4. Select Reset app preferences.
  5. Restart your Note9 and check for the problem.

Reset all settings

This procedure is separate from the previous one as it covers all settings of your Android device and not just the apps. To do this, follow the steps below:

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap General Management > Reset settings.
  3. Tap Reset settings.
  4. If you have set up a PIN, enter it.
  5. Tap Reset settings. Once complete a confirmation window will appear.

Calibrate the battery

Sometimes, Android may lose track of the actual battery levels. If this happens, the device may shut down prematurely or may have some charging problems. To recalibrate the operating system so that it gets accurate battery level readings, do the following:

  1. Drain the battery completely. This means using your device until it powers down by its own and the battery level reads 0%.
  2. Charge the phone until it reaches 100%. Be sure to use original charging equipment for your device and let it charge up completely. Do not unplug your device for at least two more hours and also don’t use it while charging.
  3. After the elapsed time, unplug your device.
  4. Restart the device.
  5. Use your phone until it completely runs out of power again.
  6. Repeat steps 1-5.

Factory reset

Wiping your phone’s software information and returning all settings to their defaults is an important troubleshooting in this situation. If the cause of the problem is software-related, factory reset will most likely help. Make sure to back your phone’s data up first before doing the reset.

To factory reset your Note9:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. 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).
  4. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  5. Press Power button to select.
  6. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  7. Press Power button to select and start the master reset.
  8. When the master reset is complete, ‘Reboot system now’ is highlighted.
  9. Press the Power key to restart the device.
  10. Let the phone run for 24 hours without adding any apps.

Contact Samsung

Should nothing change after doing everything, bad hardware must be to blame. There may be an issue with the phone’s power management system, or with the motherboard in general. A thorough physical check is needed to identify the problem. Make sure to let Samsung do the repair to ensure that you have a guaranteed fix.

Workaround: Charge by cable

In the meantime, continue using wired charging to top up the battery. Or you can even just simply ignore the non-functional wireless capability of your device. This is hardly ideal if you rely on wireless charging most of the time. But if you are the type who’s fine with wired charging, then ignoring it is a less ideal option. If you want a permanent fix though, you must let Samsung repair or replace the phone for you.
