You should use (1), 'made of', although many people will not notice if you use (2). A cell phone is made of 40 percent metals, 40 percent plastics and 20 percent ceramics and trace materials.

Strictly, we use 'made of' to talk about the materials of which a finished article is made, so my desk is made of wood, and my sister's wedding ring is made of gold. Consider 'made of' to mean 'composed of'.

We use 'made from' to talk about something that has been transformed from one form to another: I have a candle holder made from an old wine bottle, and my kids are playing in a tent made from bed sheets.
