As far as I know, Fairphone uses “conflict free” materials. This is more expensive and harder to get than just searching for the cheapest seller of any material (e.g. lithium) and just going with them. In theory this should help against child or prison labor.

Additionally, they aim to pay everyone in the chain a living wage. Which is also more expensive than just using foxxcon to produce as cheap as possible and telling them to “just add more suicide prevention nets”.

This is a good thing, but makes cost go up quite a bit I would assume. Additionally, the SoC is probably more expensive than the Snapdragon equivalent, as it is build “for industrial uses”, which normally commands a premium.
