What to do if fast charge won’t work on Galaxy S10 5G | fast charging has stopped

If your Galaxy S10 5G fast charge won’t work, there’s a number of troubleshooting steps that you can do to fix it.

Fast charge won’t work fix #1: Verify fast charging feature is ON

Fast charging is enabled by default so if you did not make any changes to it before, then it must still be on at the moment. However, we still highly recommend that you double check it before doing other troubleshooting steps. It’s simple and easy. Some may turn this feature off intentionally and then forget about it. To check:

  1. Open Settings app.
  2. Tap Device care.
  3. Tap Battery.
  4. Tap Settings (three dots on upper right).
  5. Tap Settings.
  6. Scroll down and find Fast cable charging. Move the slider to the right to turn it on.

Fast charge won’t work fix #2: Check charging accessories

When it comes to any charging issue on Samsung Galaxy devices, one of the important basic things to do is to ensure that you use official Samsung accessories. If you are not using the charging cable and adapter that came with your device, make sure that you find the original set and use them at this time. If you can’t readily find the original cable and adapter, try to borrow them from someone. Or, you can visit your local Samsung store and charge your S10 using their original cable and charger.

Sometimes, third party cables and adapter may not be compatible with a Samsung Galaxy device. Get rid of them and switch to the original ones that came with your box.

Fast charge won’t work fix #3: Perform soft reset

If fast charge still won’t work on your Galaxy S10 5G at this time, the next good thing that you want to do is to restart the device. This is one of the basic troubleshooting steps for any app issue. It’s simple and often effective in dealing with minor bugs and fixes. Charging issue may sometimes develop for many reasons, most of them due to minor bugs. Make sure to perform this troubleshooting step in this case. Here’s how: press and hold the Volume Down button and the Power key at the same time for 10 seconds or until the device’s screen turns on.

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.
  4. 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. Hopefully, your wifi troubles will get fixed by this procedure. If nothing changed though, proceed to the next suggestions.

Fast charge won’t work fix #4: Clear cache partition

If you encountered problems after updating the software, it’s possible that the problem might have something to do with a bad system cache. This cache is used by your device in order to load apps quickly. Updates may sometimes corrupt it, leading to all sorts of issues. To check if your fast charge problem has a root in the system cache, you can clear the cache partition to refresh it. Here’s how:

  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 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 to highlight “wipe cache partition.”
  5. Press the Power key to select.
  6. Press the Volume down key to highlight “yes” and press the Power key to select.
  7. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  8. Press the Power key to restart the device.

Fast charge won’t work fix #5: Turn off device when charging

If you’ve already turned on fast charge feature but the device still won’t work, the next good thing to do is try to see if charging speed improves when the phone is powered off. If fast charging works only when you powered down the device, that can mean that there may be some apps working in the background and hogging resources. This apps can be malware or viruses doing tasks that Android don’t usually allows. To check if that’s the case, you can use the built-in Battery Usage to see if there’s any particular app that’s high in the list. If an app that you don’t recognize or use that often seems to be the top user of power, it may be a poorly coded app or malware. Remove it from the system and try charging the device afterwards. 

To access Battery Usage:

  1. Open Settings app.
  2. Tap Device care.
  3. Tap Battery.
  4. Tap Battery usage.

Fast charge won’t work fix #6: Calibrate OS and battery

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.

Fast charge won’t work fix #7: Keep software updated

Keeping the software environment of your Galaxy S10 5G up-to-date is important. Not only do updates bring cosmetic changes but they also fix known bugs. Although not generally known by many Android users, installing updates sometimes also bring needed fixes for known bugs. Make sure that you don’t delay the installation of any system or app updates. By default, your tablet should notify you of any available updates but in case you turn this mechanism off, it’s high time that you manually check for them.

To check for Android or system update:

  1. Open Settings app.
  2. Tap Software update.
  3. Tap Download and install.
  4. Wait for the device to check for updates.
  5. Install the update. If there’s no new update, your phone should tell you so.

For carrier-branded Galaxy devices, or those that were provided by your carrier, there may not be an option to manually check for updates. All you have to do is to simply confirm if there’s a notification for an update and allow update installation.

To check for app updates:

  1. Open Play Store app.
  2. Tap More settings icon (at the upper left).
  3. Tap My apps & games.
  4. Tap Update all button.

Fast charge won’t work fix #8: Check for rogue apps

If you noticed that your S10 5G fast charge won’t work issue started when a new app was installed, that app might be poorly coded. Try to delete it and see if fast charge starts working normally again. 

Alternatively, you can also try to restart the device to safe mode. In this mode, no third party apps can run. If you’ve installed an app or malware that may have interfered with Android and is now causing the problem, this troubleshooting step might help. If your S10 5G charges normally and fast on safe mode only, that means that you have a bad app problem.

To restart 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.
  8. Charge the device and check if fast charge is working.

If fast charge only works on safe mode, try to uninstall an app that you think might the cause of the problem. Then, restart the phone to normal mode and check how fast charge is working. If the issue returns, you must narrow down the suspect apps. To identify which of your apps is the source of trouble, you must use elimination method. Here’s what you can do:

  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 S10 5G is still problematic, repeat steps 1-4.
