Power saving chargers

Nokia are making a phone that emits annoying beeping when the battery is full. Apparently this will save a huge amount of energy.

What would save even more energy, and not be annoying, would be for the phone to send a message to the charger to tell it to power down when the battery gets full. A properly designed switching supply should, in any case, draw very little current from the mains when the mobile device isn't taking any current.
