Apple makes most of the profits in the mobile industry, and one reason is that it keeps its manufacturing costs relatively low. The iPhone 5, for example, costs less to make than its chief rival, the Samsung Galaxy S 4. But the big surprise is that the cost of making the new iPhone 5s is just $2 more than making the iPhone 5, though the iPhone 5s packs a 64-bit processor, a fingerprint scanner, and a new type of very fast memory module called LPDDR3, all of which Apple is the first to use.

IHS Suppli, which analyzes the bill-of-materials costs for a wide range of devices, estimates that the 16GB model of the iPhone 5s costs $199 to make ($191 in parts and $8 to assemble) versus $197 ($189 in parts and $8 to assemble) for the iPhone 5. To compare, a Galaxy S 4 costs $233 in parts alone.

IHS iSuppli's iPhone 5s teardown reveals that the new tech raised Apple's costs by $14.50 -- $6 more for the processor, $1.50 more for the RAM, and $7 more for the fingerprint sensor -- but Apple was able to save $12.50 on other parts, resulting in the net materials increase of just $2.
