Very little, but yes.
Most laptop chargers are switching regulator type. Because of this, there are always small current flowing from the plug to keep the circuit alive. They never switch completely off.
Most "wall warts" type chargers contain transformer and rectifier, then the filter. They will consume very little currnent. The filter capacitor has what is called a "leakage current" where it consumes very small amount of current on constant basis.
The reality is, the small amount of current consumed by either of the type is not enough for you to be concerned about as far as their effect to the monthly electric bill is concerned. A month long usage won't even equal to a penny. The bigger concern is the safety. You might trip over the cored and *IF* something should fail in those chargers, you have a chance of having it overheat and cause fire.
My usual coure of action is, if I will be using it every day, I keep them plugged in. If I know I won't be using it for a while, I unplug them.

i will say yes and no.
from what i know electricity is the flow of electrons
therefore when the charger is in the mains surely electrons will flow through it. the flow of electrons here is what we call the electric current or electricity
the fact that it flow through doesnt mean is been used therefore elactric chargers without any indicator lights when left in the mains will conduct electricity but the current won't be used.
not withstanding chargers with indicator bulbs on it will use the electric current pass through, since the bulb will transfer the electrons into light energy.
this is why i started by saying yes and no

They do but they do not use very much if they are not charging. This applies to both mains transformer types and switched mode types.
They do not use very much power even when charging.It would probably be less than US$0.01 to charge the average phone in most parts of the world.

yes they do even if there is no phone or laptop in them the electricity still runs through them and charges you turn them off by the plug socket
