Yes. Also, heat is another way of consuming power...

Lol @ stackexchange.com:

   Inside virtually every phone charger is a transformer. 
   Transformers have a finite resistance, and hence there
   will always be current flowing through them if they are
   plugged in, even if there is no load (i.e. nothing
   charging). That's basic physics.

Basic Physics. LOL. And how that charger works with both 110AC and 230AC ;) ?
