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

If your charger has lights on, or other indicators, then it indeed wastes a tiny amount of electricity (one AA battery worth over years).
Otherwise, not. This is because without the battery/device attached for charging, the circuit is not complete and electricity is not flowing, energy is not being consumed and not being expended into light/heat.
