How to fix Galaxy S10 slow charging issue

If you have a Galaxy S10 slow charging issue, there’s a number of troubleshooting steps that you have to do in order to know where the problem lies. Follow our suggestions below.

Galaxy S10 slow charging issue fix #1: Use official charging accessories

The very first thing that you would check if you encounter slow charging issue on your S10 is confirm you are using the Samsung provided cable and adapter. This is an important consideration since third party Type-C USB cable may not be compatible or defective. Try to stick to accessories that came with the device. Cheap cables may not be able to provide the right parameters needed by your S10 to charge faster. If you are already using the official cable and adapter at this time, then simply skip this suggestion.

If you’re using the Samsung provided accessories but the cable appears torn or broken, consider replacing it with a new one to fix the problem. UBS cables is composed of a number of tiny wires inside and if there’s not enough working wires, there may not be enough power to allow fast charging on your S10.

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

5. Tap Settings.
6. Look for fast cable charging and toggle the switch. Make sure that it’s moved to the right to turn it on.

Galaxy S10 slow charging issue fix #3: Restart the device

1. Press and hold the Power + Volume Down buttons for approximately 12 seconds or until the device power cycles. Note: Allow several seconds for the Maintenance Boot Mode screen to appear.
2. From the Maintenance Boot Mode screen, select Normal Boot. Note: Utilize the volume buttons to cycle through the available options and the lower left button (below the volume buttons) to select. Allow up to 90 seconds for the reset to complete.
3. If Maintenance Boot Mode screen won’t show, then your device does not have it. Simply wait for the device to power down completely.

Galaxy S10 slow charging issue fix #4: Turn off device while charging

If your Galaxy S10 is still slow charging at this time, try to check if it charges slowly. If it does, it’s possible that there are a number of apps running actively or in the background that consumes power. Try to see if your phone resumes to fast charge when it’s powered off. If fast charging works when your S10 is shut down, that’s means there may be apps you need to close. In some cases, malware or a number of them may also run in the background doing tasks that requires a lot of energy. If this happens, it may appear that your phone may not be fast charging. Even if fast charging is enabled, it may take several hours to fully charge the battery. Try to check Battery usage tool and see if there are apps that are unusually high up in the list. If these apps are not relatively unknown, or if you did not know them at all, consider removing them from the system.

Galaxy S10 slow charging issuefix #5: Clear cache partition

In order to load apps quickly, Android uses a set of temporary files called system cache. Sometimes, this cache may become corrupted or outdated resulting to performance problems or bugs. To see if you have a bad cache problem, try to delete the system cache with these steps:

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.

Clearing the cache partition can be done safely and it won’t result to loss of your personal data. There’s no need to worry about losing your important data at this time.

Galaxy S10 slow charging issue fix #6: Calibrate Android 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.

Galaxy S10 slow charging issue fix #7: Charge on Safe Mode

In case there’s a rogue app causing Galaxy S10 slow charging issue, the next troubleshooting step for you is to see if fast charging works on safe mode. If it does, that means that one of the apps is the reason.

To restart 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.

When running on safe mode, all third party apps will be suspended and won’t load at all. So, if your Galaxy S10 charges normally and fast charge starts working again, it means that an app is to blame. 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 is still problematic, repeat steps 1-4.

Galaxy S10 slow charging issue fix #8: Keep the system up-to-date

Keeping Android and apps updated may not mean much for a lot of users but it’s just as important as any other solutions we mention so far. Some Android problems are only fixable by changing some codes and since the fix happens without a user knowing it, not many are enthusiastic about doing it. Some even prevent their device to not download updates on purpose. If you are one of them, we recommend that you stop doing it and install whatever updates are pending right now.

Galaxy S10 slow charging issue fix #9: Restore software settings to defaults

The last device troubleshooting to do is factory reset. This wipes all software settings and return them to their factory state. Factory reset will delete all your apps and personal data so be sure to create a backup ahead of time.

2. Also, you want to make sure that you remove your Google account. If your problem prevents you from doing that, then simply skip this step.
3. Turn off the device. This is important. If you can’t turn it off, you’ll never be able to boot to Recovery Mode. If you are not able to shut the device off regularly via the Power button, wait until the phone’s battery is drained. Then, charge the phone for 30 minutes before booting to Recovery Mode.
4. Press and hold the Volume Up button and the Bixby button at the same time.
5. While still holding the Volume Up and Bixby keys, press and hold the Power button.
