  Twitter @wifixit_iphone
  
• Theoretically this mod works for any phone which support USB charging and has extra 1.5mm gap between back cover and battery.
  
• But this mod will not work on the phone which comes with a metal cover (IE: I897 , iPhone 4-4s),
  Because metal is kind of electromagnetic shielding material, it will block magnetic energy.
  
  
• If you have a plan put this on iPhone 4 or 4S , You will have to separate the metal sheet from the glass back cover, then trim a hole then bind these back.(Twitter me about the details [MENTION=268591]wifi[/MENTION]xit_iphone)
  
• Alert: DO Not Trying to connect this mod directory to the battery connector.

Ok Let's get started !!!!!!!!:highfive:

(1) At first I'm going to introduce what's in this mod kit.


-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

As I know most of people will buy a pixi or pre back cover then peel the coil and sticker from it.
But u should be very careful when peeling off the silver sticker,
Any bend or damage will increase the risk of disturbing energy transfer.


(1) Test before installing or soldering the coil to your phone.



Once you put the coil and sticker above the touchstone you will hear some buzzing .

5.60v Non loaded voltage is normal..



(2) Find the Negative and Positive Terminal on your phone. MARK DOWN
This is ATT SAMSUNG GALAXY S4.

(This is just for reference cause some carrier has their own version )
( Some version of S4 will not come with this connector,if you know circuit board you can solder wire directory to the component which controls USB CHARGING )

(3) Now we can work on the coil part.

Desolder two square copper
The red big square area is positive u set ur positive terminal in anywhere within this area.

(4) Trim the Nickle stick or copper tape
On S4 I just cut two thick nickel stick and solder these two connectors (in the first pic) to the stick.

Align the connector before you bonding the coil to your back cover.
