SAN FRANCISCO—The 16-Gbyte version of Apple Inc.'s iPhone 4 carries a bill of
materials (BOM) cost of $187.51, keeping with Apple's strategy of maintaining
hefty profit margins on the popular smartphone, according to a teardown analysis
conducted by market research firm iSuppli Corp.
A number of firms, including UBM TechInsights (owned by the same parent
company as EE Times) have conducted teardown analyses of the iPhone since
its release on June 24. The teardowns have revealed that Apple is using many of the
same parts in iPhone 4 that it uses in its iPad tablet.
ISuppli (El Segundo, Calif.) estimated the BOM of the 3GS in 2009 at $170.80;
the 3G in 2008 at $166.31 and the first iPhone in 2007 at $217.73. ISuppli noted
that the BOM accounts only for hardware costs and does not include other
expenses such as manufacturing, software, marketing, distribution and royalties
and licensing fees. Kevin Keller, a principal analyst for iSuppli's teardown
services, said the BOM of the iPhone 4 closely aligns with those of previous
iPhones. "With the iPhone maintaining its existing pricing, Apple will be able
to maintain the prodigious margins that have allowed it to build up a colossal
cash reserve—one whose size is exceeded only by Microsoft Corp," Keller said.
The 16-Gbyte iPhone 4 sells for $199 plus shipping on Apple's website.
In its teardown analysis, iSuppli noted that the body of the iPhone 4
incorporates the phone's antenna. ISuppli praised the re-designed housing as
innovative, but some analysts have speculated that the integrated antenna could
be the cause of reception
issues that some users have experienced.
The wireless subsection of the iPhone 4 is smaller than in previous iPhones
because of increased integration of the RF functionality into the core chipset
components, despite the presence of an additional air standard: High-Speed
Uplink Packet Access, iSuppli said.
"Out of the nearly 300 cell phones torn down by iSuppli, the iPhone comes the
closest to integrating the entire wireless interface—including all the
supporting radio frequency modules—on a single chip," Keller said.
The LCD display represents the single most expensive component in the iPhone
4, costing $28.50 and accounting for 15.2 percent of the product’s total BOM,
iSuppli said. The 3.5-inch display uses advanced low-temperature polysilicon and
in-plane switching technology and features a 960 by 630 resolution—four times
that of the iPhone 3GS.
While the display is not labeled, iSuppli believes the most likely supplier
is LG Display, the firm said, but added that Toshiba Mobile Display is also a
The next most expensive single component of the iPhone 4 is the NAND flash
memory, iSuppli said. In the 16-Gbyte version of the iPhone 4, the NAND costs
$27 and accounts for 14.4 percent of the BOM, according to iSuppli. In the
iPhone 4 torn down by iSuppli, the NAND flash was supplied by Samsung
Electronics Co. Ltd., although Apple could be employing other sources as well,
Samsung also supplies the next costliest part, the 4 Gbits of mobile double
data rate SDRAM, priced at $13.80, or 7.4 percent of the BOM, iSuppli said.

I'm still amazed at how the parts counts to cost ratio seem to fall so precipitously every generation these days. The size and cost of such capability just 35 yrs ago would have been enormous - would have taken 100k dollars or more and a Suburban Truck to carry it.
