Samsung's latest Galaxy smartphone brings a better camera and other improvements, but no ground breakers. According to an estimate by IHS, the device costs about $255 to build. The U.S. version of the Galaxy S7 with 32 gigabytes (GB) of NAND memory carries a bill of materials (BOM) of $249.55, which rises to $255.05 when the manufacturing cost is added, according to results from the IHS teardown of a phone purchased from Verizon. The retail price of the Galaxy S7 at Verizon is $672. As another point of reference, Apple’s 16GB iPhone 6s has a BOM of $187.91 and retails for $649.

"The Galaxy S7 is the upgrade Samsung had to do, but there’s not a lot of trailblazing happening on the device," said Andrew Rassweiler, senior director of cost benchmarking services at IHS. "It’s more a case of small refinements. Samsung is spending more and more on its bill of materials, but they’re selling something that doesn’t hold its price as well as an Apple product. Samsung’s S7 BOM is almost $60 more than a comparable iPhone."

The IHS teardown revealed that not much has changed on the display front from the prior generation phone. The S7’s Samsung-manufactured 5.1-inch Quad HD Super AMOLED touchscreen display is the same size and resolution (2560x1440 pixels, 577 PPI) as the S6 and costs $55.

Found in the Verizon S7 sample torn down by IHS is Qualcomm’s latest silicon, the Snapdragon 820, which offers generational improvements over the S6’s Snapdragon 810. The new chipset affords better power efficiency, faster battery charging and includes a speedier data bus that supports LPDDR4 memory with a capacity up to 4GB—the highest density to date in a smartphone. The Snapdragon 820 is capable of supporting LTE CAT-12, which provides 33 percent faster theoretical data throughput than the CAT-9 capabilities of the Snapdragon 810 (600 Mbps versus 450 Mbps). IHS puts the entire cost of the Qualcomm chipset solution (Snapdragon 820 and other Qualcomm supporting components) at $62, giving Qualcomm one of the largest component supplier footprints on the S7 BOM from a dollar perspective.

The Samsung NAND flash memory found on the S7 is 32GB and comes in at a cost of $7.25.

DRAM, or dynamic random access memory, on the S7 is from SK Hynix and is of the LPDDR4 4GB package-on-package (PoP) flavor. IHS estimates its price tag at $25. Samsung and other Qualcomm apps processor-based designs typically feature more memory than Apple designs. The iPhone 6s has only 2GB of LPDDR4 DRAM.

For the S7 camera, the IHS teardown found that Samsung backtracked on camera pixel inflation in favor of technology improvements. The S7 features a 12 megapixel (MP) primary camera module, whereas the S6 had a 16MP module. The camera module features a 1.4μm-pixel-based image sensor equipped with dual pixel technology for faster autofocus capability, improved image quality in low-light situations and deep trench isolation for less pixel crosstalk. The front-facing camera is 5MP.

"Going backwards from 16 megapixels to 12 megapixels buys Samsung larger pixel sizes for better low-light performance," said Wayne Lam, principal analyst for mobile devices and networks at IHS.

While Samsung is offering only a 32GB version of the Galaxy S7 in the US—25GB of which is user accessible—it has brought back microSD expandable storage that accepts cards of up to 200GB.

A step up from the S6’s IP67 rating, the S7 has a water resistance rating of IP68, indicating it is water resistant in up to five feet of water for up to 30 minutes. The IHS teardown revealed silicone seals and sealed components throughout the phone design to inhibit water ingress.

The S7 features a beefier 3000mAh Li-Polymer battery than the 2600mAh found in the S6, likely to handle the phone’s higher processor performance and provide improved battery life. The battery is a fast-charge type and supports wireless charging.

The teardown revealed a copper heat exchanger for thermal management. A design feature typically only found in notebook and desktop PCs, heat exchangers have only been seen in one other smartphone, the Nokia Lumia.

On the sensor front, the S7 includes the usual accelerometer, gyroscope, compass, fingerprint sensor, pressure (barometer) sensor and optical pulse sensor. The sensors add $4.65 to the cost of the phone.
