How to fix Galaxy Note10 won’t charge | cable charging not working

Charging problems are some of the perennial issues on smartphones. In this troubleshooting episode, we’ll show you the solutions to fix a Galaxy Note10 that won’t charge. We’re trying to address a cable charging issue here so if you have a wireless charging problem on your device, we’ll address that on a separate article.

Why Galaxy Note10 won’t charge and how to fix it

There can be many reasons why your Galaxy Note10 won’t charge. Below are some of the common causes for most charging issues on Samsung Galaxy devices:

  • Defective USB cable or adapter
  • Charging port malfunction
  • Moisture detected error or water in the port
  • Bad app 
  • Unknown software glitch
  • Unknown motherboard issue

In this troubleshooting guide, we’ll show you how to fix charging problems on the Note10.

Galaxy Note10 won’t charge fix #1: Check charging accessories

One of the most common reasons why charging issues occur is bad charging accessories. Just like the phone itself, the charging cable and adapter can break as well. Be sure to check the accessories for visible signs of damage. If the cable is broken or bent, there may not be enough power being transferred to the battery during charging. The same is true if the adapter, the thing that you connect the other end of your cable to, is malfunctioning. To know if the reason why your Galaxy Note10 won’t charge is caused by the cable or adapter is by using another set of accessories. If you have another family member who has a Galaxy Note10 adapter and cable, use them to charge. If your Note10 charges normally, replace the ones you have. Be sure to get original Samsung charging accessories to avoid damaging your Note10. 

As much as possible, try to use official Galaxy Note10 charging accessories. Other Samsung chargers may not be compatible with your Note10, or may not be able to provide the fast charging capability that the Note10 charger has.

Galaxy Note10 won’t charge fix #2: Charge the device

If you’ve confirmed that you now have a good working cable and adapter, begin charging your Note10 again. This time, be sure let your phone charge for at least 30 minutes before you do something with it. We suggest that you turn off the phone for 30 minutes while charging. This should be enough time to fully charge the battery from 0-100%. 

Sometimes, Android may lose track of the actual battery levels. 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.

Galaxy Note10 won’t charge fix #3: Inspect charging port

If your Galaxy Note10 still won’t charge, the next good thing to do is to do a visual check on the charging port. You want to make sure that the port is clean and there’s no debris, dirt, or foreign object that blocks the tip of the cable. If you see dirt or debris inside, use a can of compressed air to take it out. Avoid sticking anything into the port as that might damage the system. 

Galaxy Note10 won’t charge fix #4: Forced reboot

Charging issues can sometimes be caused by minor glitch in the software. Such a situation may be fixed by restarting the device. If you haven’t tried this yet, be sure that you do it this time. Try restarting it normally first by pressing the Power button to access the boot menu. Then, select Restart option and see if that works.

Another way to restart the device is by pressing and holding the Volume Down button and the Power key at the same time for 10 seconds or until the device’s screen turns on. This simulates the effect of having disconnected the battery from the device. If this works, this may unlock the device.

If doing the regular restart won’t help, then try this:

  1. Press and hold the Volume Down button first and don’t release it.
  2. While holding it down, press and hold the Power key.
  3. Keep both keys held down for 10 seconds or more. 

The second restart procedure tries to simulate the effects of removing the battery pack. On older devices, disconnecting the battery is often an effective way in fixing unresponsive devices. If nothing changed though, proceed to the next suggestions.

Rebooting your device regularly at least once every week can be beneficial. If you tend to forget things, we suggest that you configure your phone to reboot on its own. You can schedule it to do this task by doing these steps:

  1. Open Settings app.
  2. Tap Device Care.
  3. Tap the 3-dot at the top.
  4. Select Auto restart.

Galaxy Note10 won’t charge fix #5: Charge on Safe Mode

If your Galaxy Note10 started having charging issues after installing a new app, you may have a third party issue. The best thing that you can do in this case is to try to restart your phone to safe mode. On SAfe Mode, all third party apps are suspended and can’t run. If you can’t remember the app, try to restart the device to safe mode and see what happens. So, if the problem goes away on safe mode only, that’s a clear indication that the cause is a bad third party app. To boot the device to safe mode:

  1. Press and hold the Power button until the Power off window appears then release.
  2. Touch and hold Power off until the Safe mode prompt appears then release.
  3. To confirm, tap Safe mode.
  4. The process may take up to 30 seconds to complete.
  5. Upon reboot, “Safe mode” appears in the lower-left of the home screen.
  6. Charge the phone while on Safe Mode.

Remember that third-party applications are disabled in this mode so what you can use are pre-installed apps. If Galaxy Note10 charges normally to safe mode successfully, that means that the problem is due to a bad app. Uninstall the app you recently installed and see if that will fix it. If the problem remains, use the process of elimination to identify the rogue app. Here’s how:

  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 Galaxy Note10 still won’t charge normally (but works on safe mode), repeat steps 1-4.

Galaxy Note10 won’t charge fix #6: Check for moisture detected error or water damage

Are you getting moisture detected error every time you try to charge? If yes, then the charging port is wet or has traces of moisture in it. Wipe the phone and let it dry for a few hours before charging again.

The Galaxy Note10 has IP68 rating, which means that it’s water- and dust-resistant. However, this resistance is not absolute and can be compromised if you don’t take care of the device. While the phone can take water splashes, it’s not recommended that you swim or dive with it. You don’t want to intentionally drop it in a pool or ocean just to check the effectiveness of IP68 rating. Sometimes, this protection may not work as advertised. 

In the event that you accidentally exposed the device to water, one of the things that you want to do is to immediately wipe with clean, soft cloth to dry it externally. Then, you want to let the water drip from the exposed charging port. If there’s moisture or water in the port, the device won’t charge at all. This is to prevent itself from shorting, which can fatally damage its electronics. What you want to do in this case is to thoroughly dry the phone by wiping it and allowing water to clear out. Water naturally evaporates in room temperature after a few hours so just leave the device. DO NOT try to hasten the drying process by blowing into the port. That can potentially push moisture inside and cause a problem.

If your Galaxy Note10 still refuses to charge at this stage, you must consider returning its software to defaults. This is the final solution that you can do to check if the cause of the problem is software-related. Be sure to create a backup of your personal data before wiping the phone.

The other side of a charging issue can be caused by bad hardware. If you’re not careful when plugging or unplugging the charging cable, you may accidentally damage the charging port system. This can lead to charging problems. Other reasons may include unknown hardware errors and malfunction that may only be known after a thorough diagnostics. If factory reset won’t help at all, we suggest that you visit your local Samsung store or Service Center so you can set up an appointment for repair or replacement.

Perhaps you want to create a backup of your files first before visiting your local Samsung store but the phone is already low on power. In this situation, you can try to use wireless charging to top up the battery. Wireless charging is really helpful especially if the problem is caused by a bad charging port.
