Hardware and Design Samsung Galaxy S6 – The Galaxy S6 line retains similarities in design to previous models, but now uses a unibody frame made of aluminium alloy 6013 with a glass backing, a curved bezel with chamfered sides to improve grip, and the speaker grille was moved to the bottom. The devices are available in “White Pearl”, “Black Sapphire”, and “Gold Platinum” color finishes; additional ” Blue Topaz” and “Emerald Green” finishes are exclusive to the S6 and S6 Edge respectively. The S6 carries some regressions in its design over the S5; it is no longer waterproof, does not contain a MicroSD card slot, reverts to a USB 2.0 port from USB 3, and has a non-removable battery.
The Galaxy S6 line is powered by a 64-bit Exynos 7 Octa 7420 system-on-chip, consisting of four 2.1 GHz Cortex-A57 cores, and four 1.5 GHz Cortex-A53 cores, and 3 GB of LPDDR4 RAM. The processor is Samsung’s first to use a 14 nm FinFET manufacturing process, which the company stated would improve its energy efficiency. It will be available with 32, 64, or 128 GB of non-expandable storage, implementing Universal Flash Storage 2.0 standards. Both devices feature a 5.1-inch 1440p Super AMOLED display; similarly to theGalaxy Note Edge, the S6 Edge’s display is slightly curved around the horizontal sides of the device, although not as aggressively as the Note Edge.
For its rear-facing camera, Galaxy S6 uses the same image sensor with optical image stabilization as the Galaxy Note 4, albeit with a f/1.9 aperture, object tracking autofocus, real-time HDR, and using the infrared of the heart rate sensor for calibrating white balance. Samsung claimed that the camera upgrades would allow it to have better low-light performance. The front-facing camera was also upgraded to 5 megapixels with a similar aperture. The fingerprint scanner in the home button now uses a touch-based scanning mechanism rather than swipe-based; double-tapping the Home button activates the camera app. Galaxy S6 includes a 2550 MAh battery, while the S6 Edge includes a 2600 MAh battery. The Galaxy S6 line supports both the Qi and Power Matters Alliance wireless charging standards.
