THE APPLE IPHONE 4S and Samsung Galaxy S II are two of the best smartphones around so we've decided to put them head to head to see which one comes out on top.
In the beauty stakes the handsets are very similar, with both available in black or white. The most noticeable difference is the display, with the Galaxy S II having a screen that is almost an inch bigger the Iphone 4S at 4.3in compared to 3.5in.
Despite being the bigger device, the Samsung is extremely slender with a thickness of just 8.49mm and weight of 116g. The downside is the cheap, plastic cover on the back, which slightly lets down the overall finish. Apple's device is thicker and heavier at 9.3mm and 140g respectively.
Even though the Iphone 4S has a lovely glass finish, the Galaxy S II is thinner, lighter and more a tad more comfortable to hold. The Iphone 4S also appears to be much more fragile. In drop tests, we've seen the Iphone screen has shattered whilst the Galaxy S II survived the same punishment relatively unscathed.
We could run all kinds of benchmarks to gain figures on both phones to see which is better, but it's the real life day to day performance that really matters. Both phones are quick when it comes to handling everyday tasks. The Galaxy S II has a 1.2GHz dual-core ARM Cortex-A9 chip and the Iphone 4S has the A5 dual-core processor found in the Ipad 2. However, the exact speed of the chip in the Iphone is not known, but is believed to around 800MHz.
From these numbers Samsung looks to have one up on its bitter rival. This is far from the truth in reality, though. Navigating the interface and loading apps is smooth on both devices, but if we had to pick a winner we would choose the Iphone because we saw slightly less lag.
When playing games the phones are again capable of rendering demanding 3D content smoothly. We tested games that are available for both phones such as Heavy Gunner and could see no difference in performance.
However, in the future there could be games that only the Iphone 4S will be able to run as developers begin to use the graphical capabilities of the A5 chip.
