If you don't already know all about the Samsung Galaxy S II, where have you been the past two months? The successor to one of the most popular Android handsets to date carries a burden of expectation almost as sizable as its 4.3-inch Super AMOLED Plus screen. It promises to be thinner, lighter, and faster than the Galaxy S that preceded it, while garnishing Android 2.3.3 with a set of TouchWiz customizations that might actually enhance, rather than hinder, the user experience. As such, the Galaxy S II earns Samsung full marks for ambition, but does this slinky new smartphone live up to its interstellar hype? The answer, as always, can be found after the break.
Hardware
The Samsung Galaxy S II is 8.49mm (0.33 inches) thick. We whipped out a ruler and checked, it's true. Admittedly, that measurement expands a little at the handset's bottom, where a curvy bump houses its loudspeaker, and around the camera compartment, which protrudes ever so slightly from the rest of the body, but even at its thickest point, this phone doesn't allow itself to go beyond the 1cm mark. Given the veritable spec sheet overload that Samsung has included within the Galaxy S II, we consider its thin profile a stunning feat of engineering. In terms of the pursuit of the absolute slimmest device, NEC's MEDIAS N-04C is still the champ at 7.7mm, but global audiences should feel comfortable in replacing the Sony Ericsson Xperia Arc, which measures 8.7mm at its thinnest point, with the Galaxy S II for their benchmark slim device.
Display
The Galaxy S II's screen is nothing short of spectacular. Blacks are impenetrable, colors pop out at you, and viewing angles are supreme. This would usually be the part where we'd point out that qHD (960 x 540) resolution is fast becoming the norm among top-tier smartphones and that the GSII's 800 x 480 is therefore a bit behind the curve, but frankly, we don't care. With a screen as beautiful as this, such things pale into insignificance. And we use that verb advisedly -- whereas the majority of LCDs quickly lose their luster when you tilt them away from center, color saturation and vibrancy on the Galaxy S II remain undiminished. It is only at extreme angles that you'll notice some discoloration, but that's only if you're looking for it and takes nothing away from the awe-inspiring experience of simply using this device.
Battery life
The story of the Galaxy S II's battery life cannot be told without returning to its luscious screen. Being an OLED panel, the 4.3-inch display here doesn't use one single backlight as LCD screens do, and instead only illuminates the pixels that are needed to actively display content. This is the reason why it can generate truer blacks than any backlit panel, but it also permits the user to optimize battery life by doing such things as switching to a darker wallpaper or reading ebooks against a black background. We didn't actually bother with such tweaks, we were too busy exploring every one of the myriad features on this phone, but the option's there as an extra dimension of obsessive control if you care for it. As to the Galaxy S II's actual endurance, we found it highly competitive with the latest batch of Android phones. After 20 hours, half of which were filled with the above tinkering and exploration, we managed to drag the Galaxy S II down to 15 percent of its original charge. This was with our usual push notification suppliers, Gmail and Twitter, running in the background and while constantly connected to our WiFi network.
