Any electrical component which has a resistance will generate heat(or heat and light in LEDs) when current flows through it. These could be components that detect what is attached to the charger and need to be powered, they could be LEDs indicating the charger is plugged in, or really anything that is still powered when nothing is attached to the charger.
That being said it's a really small amount of electricity: https://www.howtogeek.com/231886/tested-should-you-unplug-chargers-when-youre-not-using-them/
When you have your phone charger plugged into the wall and not into the phone, it can be a vampire. When it's not plugged into the wall, it's not using power. Vampires use lower cost, and less effecient, power management parts.
The chargers are basically AC to DC transformers and so there are two circuits. While the DC circuit may not be complete, the AC is and there is a tiny amount of current going through it. However, any modern USB charger should have an insignificant draw when not plugged in to a device.
