[* black] Let's play "Is it Magnetic?". The rules are pretty much self-explanatory.
[* black] Would you look at that, it's magnetic. We suspect that the charging coil's sticker backing works like a [http://en.wikipedia.org/wiki/Transformer#Cores|transformer core|new_window=true], made of up ferrous material that "serves to greatly reduce the magnetizing current and confine the flux to a path which closely couples the windings."
[* black] Tl;DR: we're thinking this sticker improves the inductive charging efficiency.
[* icon_note] [https://www.ifixit.com/User/309817/David+Wei|David] clears things up for us:
[* black] "It is most likely a shielding for the main circuit board. When you are focusing a lot of energy through space, you cannot guarantee it will all end up on the receiver coil. Therefore you will need a shield to absorb any staystray energy. Just think, if anya wire just happenhappens to be the perfect shape to receive energy, it will likely cook the circuit."
