To check:

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.

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:
- Open Settings app.
- Tap Device care.
- Tap Battery.

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 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:
- Boot to safe mode.
- Check for the problem.
- 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.
