Add wireless charging to your Samsung Galaxy S3 (photos)

Grab a small knife and carefully remove the circuit board and the copper coil. These are the parts that allow your phone's battery to receive a wireless charge. Finally, remove the metal discs and set them aside.

Then, before you remove anything else, grab a small piece of paper (translucent wax paper works here), lay it on top of the circuitry, and carefully plot where each component is. Be sure to include the coil and the four metal discs. Set the template aside -- you'll refer to it again in a bit.
