I'd read that cell phone chargers are generally not 'phantom load', that is
they don't consume any power when the phone is not connected. Not sure if
that is the case for all of them but one way to tell is if the transformer
is warm to touch even when the phone is not connected.

If you are really concerned there is a device you can buy known as the
Kill-A-Watt. It will measure how much power any plug-in device is
actually drawing, and also tell you the accumulated KWh over a period of
time.
