Exclamation mark in yellow triangle shows when charging if switch off, and takes long to charge my phone for more than 6 hours even when fast charging is on not like before when it took less than 2 hours.

Hi there. I have a S10E and have a similar problem. When i plug my phone tobthe wall socket the triangle sign appears whilst charging. When i plug it into a Usb port like Laptop/PS4  it doesn't show the Truangle. What is the problem here?
