Samsung Galaxy S4 bill of materials estimated at $236

Samsung's new Galaxy S4 flagship smartphone carries a $236 (£156) bill of materials, which is 15 per cent higher than the company's previous device, the Galaxy S3.

If you include the $8.50 (£6) manufacturing cost, the 16GB HSPA+ version of the Galaxy S4 costs $244 (£161) to make. That's $30.40 (£20) more than the equivalent version of the Galaxy S3, according to a report from IHS iSuppli. The LTE version of the S4 is actually slightly cheaper, at $241 (£159).

IHS noted, however, that since the Galaxy S4 has not yet been released, the company is relying on specs released by Samsung and said its estimates could change once it completes a full teardown.

The most expensive part of the Galaxy S4 is the $75 (£50) 5in display, which comes in at a resolution of 1,920 x 1,080 pixels. The Galaxy S3 boasts a 4.8in, 1,280 x 720 pixel display, which costs $65 (£43). "This represents the single largest area of cost increase for the S4 compared to the S3," IHS found.

"While many brands have released smartphone models using full-HD LCD displays, the S4 represents the first with an AMOLED display at this resolution," Vinita Jakhanwal, director for small and medium displays at IHS, said in a statement. "Reaching a true pixel density greater than 300 ppi has been a challenge for AMOLED display makers. However, Samsung was able to enhance AMOLED display performance by implementing new technologies that also drove up the cost of the display."

IHS estimated that the HSPA Galaxy S4 is sporting an Exynos 5 Octa, which costs $30 (£20) to the $17.50 (£12) chip in the Galaxy Ss.

Last week, Qualcomm confirmed that the LTE Galaxy S4 will launch with a 1.9GHz Qualcomm Snapdragon 600 processor. This is especially important for US users because, while Qualcomm and Samsung aren't saying, US models of the phone are likely to run on Qualcomm's chip rather than Samsung's Exynos 5 Octa because of Qualcomm's strong relationships with US carriers.

IHS said the Qualcomm solution is cheaper at $20 (£13) rather than $30 (£20) for the Exynos 5 Octa, helping to make the LTE version less expensive. The LTE version also uses a lower-cost wireless LAN/Bluetooth/FM/GPS subsystem running $5.75 to $9 (£4 to £6).

The Galaxy S4's 13-megapixel camera, meanwhile, costs $20 (£13), while the sensors come in at $16 (£10). That's slightly higher than the $12.70 (£8) for the sensors in the Galaxy S4, but the S4 includes humidity, temperature, and IR gesture sensors not found in the S3 .

Samsung will start shipping the Galaxy S4 in April; pricing has not yet been announced.
