I began with a whole but broken iPhone 6. I used a suction cup to pull of the screen, a plastic prying lever, and several small screw drivers: a flat head, a Phillips head and a small torx head for the first two bolts on next to the lightening port. 
I proceeded to slowing peal away the layers.
There are so many parts in the iPhone it is hard to say it is made from one primary material. Clearly, when holding on I phone we can readily identify the CNC’ed aluminum receiver and the LCD touch screen. Once inside there is the battery which takes up a 50% of the real estate inside the receiver. Surrounding it is a complicated network of connections between chips, plugs and buttons.
There were several chips with numbers on them:

- 1AA1C7H44872 02AG16QAY
- QUALCOMM MDM9625M OBA B4Y882.0 H244403: this is a mobile data modem
- AVAGO A8020 KA1444 JR172 OB00M: power amplifier
- AVAGO A8010 KA1444 JP157 OT00M: power amplifier
- 77356-8 08161.1 1446MX:power amplifier
- 77802-23 6411573.1 1446 MX: power amplifier
- 77803-20 6415705P 1447 MX: power amplifier
- APPLE A8: processor
Two design design elements I found interesting were the polished logo on the back of the receiver and the shock absorbing corners. The log was interesting because it was a separate piece from the receiver that fit into holes cut into it. I tried to pry it out but I was unable to The corners showed how the receiver cleverly hid shock absorption into the phone.
