ELI5: If i leave my charger plugged in and the switch is on without any device charging, does it 'waste' electricity? Why/why not?

Generally, yes, there will be a small amount of electricity flowing. However, it is so small that it amounts to pennies per year in cost. If you unplugged everything you weren’t using and only plugged it in to use it, there would be no notable reduction in your electricity bill. Most of your bill is major appliances and heating/air conditioning.
