iPhone 4S vs LG Optimus 2X P990: Price & Specifications

Why are we comparing the superior iPhone 4S to the LG Optimus 2X P990? Because the latter is the cheapest dual core smartphone currently on the market with its unlocked version available from Expansys (opens in new tab) for only £260, nearly half the price of the cheapest iPhone 4S.

How do they compare? Sizewise, the iPhone 4S is the smaller of the two by far (123.9x63.2x10.9mm vs 115.2mmx58.6x9.3mm) but oddly enough, it is heavier than the Optimus 2X (140g vs 139g) which makes the former feel reassuringly heavy.

Both have dual core ARM Cortex-A9 based SoC. Apple hasn't confirmed the clocked speed on the A5 in the iPhone 4S while the Optimus 2X, Nvidia Tegra 2, is clocked at 1GHz.

We still don't know how much RAM the iPhone 4S - which is powered by iOS 5 - has, while the Optimus 2X - which runs on Android 2.2 Froyo - comes with 512MB RAM.

The iPhone 4S comes either in 16GB, 32GB or 64GB versions while the Optimus 2X only comes with 8GB. That said, you can purchase an 8GB microSD card for around £8 and and a 32GB one for well under £30 to boost internal storage to around 40GB.

The Optimus 2X has a bigger screen (4.0-inch vs 3.5-inch) but a much lower screen resolution (800x480 pixels vs 960x640 pixels) compared to the iPhone 4S. Unsurprisingly, the iPhone 4S wins hands down when it comes to pixel density.

Both handsets are equipped with an eight-megapixel camera with full HD recording capabilities. But we believe that the one on the iPhone 4S is the superior one both in terms of quality and shooting speed.

Both also offer video content mirroring although you'd need an additional connector for the iPhone 4S while the Optimus 2X already comes with HDMI out.

When it comes to connectivity though, the iPhone 4S is the hands-down winner; Bluetooth 4.0 (vs 2.1), a true World Phone (with CDMA) and improved 3G speeds (with HSDPA).

The battery life in 3G (talktime for the iPhone 4S currently stands at eight hours) while the Optimus 2X is almost up there with 7h50m.
