by Jerry D on February 28, 2011

How does the ageing Apple iPhone 4 fare against the new breed of dual-core super-phones? We put it into the ring with the LG Optimus 2X, oil them both up and cause a little techno-wrestlemania…

In terms of wireless roaming, the smoothie Optimus 2X includes 3G/HSDPA (10.2Mbps), 802.11b/g/n Wi-Fi And Bluetooth 2.1 with A2DP. The iPhone 4 packs 3G/HSDPA (7.2Mbps), Bluetooth 2.1 with EDR and 802.11b/g/n Wi-Fi. This first round is a tie. (1-1)

Size & Weight:

Get the spec sheets out and the Optimus 2X and the high-resolution iPhone 4 measure 123.9 x 63.2 x 10.9mm and 115.2 x 58.6 x 9.3mm respectively. The iPhone 4 is the thinner of the two – Apple made a BIG deal about it being the “world’s thinnest smartphone”. In terms of weight, the LG Optimus 2X weighs 139g, while the iPhone 4 is 137g. (1-2)



The Optimus 2X’s camera boasts an impressive 8.0 Megapixel resolution. Frills include autofocus, an LED flash, geo-tagging and 1080p video recording. The highest resolution it supports is 3264 x 2448 pixels. There’s also a front-facing camera for video chat/Skype.

Even with tap to focus functionality, an LED flash, geo-tagging and HD video recording (720p), the iPhone 4′s 5.0 MP camera can’t match the Optimus 2X for raw Megapixels. That’s not to say it’s a bad camera. You can take some awesome snaps with it. Like the 2X, the iPhone has an extra camera on the front for Skype video calling and FaceTime. (2-2)


A next-gen phone with last-gen screen technology? Rub your eyes as much as you want, the Optimus 2X only boasts a touch-sensitive TFT LCD display, measuring 4.0 inches and delivering a resolution of 480 x 800 pixels. Ho, and as they say, hum. In terms of pixel density, the pixels per inch (PPI) measurement here is 233.25.

The 3.5-inch touch-sensitive Retina display on the iPhone 4 might be smaller by half-an-inch, but it still rocks the highest resolution in town at 640 x 960 pixels. With a whopping 614400 pixels onscreen, the pixel density is an amazing 329.714 pixels per inch. (2-3)


These days, speed is crucial and while the iPhone 4 was speedy last year, it’s been overtaken by a new breed of dual-core processors. Case in point: the LG Optimus 2X has been constructed around an NVIDIA Tegra 2, featuring a 1GHz dual-core ARM Cortex A9 chip and powerful GeForce graphics. The 1GHz A4 CPU inside the iPhone 4 is still potent and zips the UI along. But it lacks the future-proofing of a dual-core chip. (3-3)


The LG Optimus 2X is built around Android 2.2 (Froyo), upgradeable to 2.3 (Gingerbread) later in the year. The iPhone 4 runs iOS4, which needs very little introduction and has access to the largest library of games, utilities and time-wasting fart applications on the planet. (3-3)


The 32GB of memory in the iPhone 4 beats the 8GB capacity of the Optimus 2X. The Optimus 2X also features a microSD slot to boost the storage to a roomier 40GB. The 32GB on the iPhone 4 can’t be extended as the handset lacks a memory card slot. (4-3)

Battery life:

Calculating battery life is tricky. But LG claims 8.0 hours of talktime for the Optimus 2X, compared to 7.0 hours for the iPhone 4. Standby times are 400 hours and 300 hours respectively. A first place result for the Optimus 2X pushes it further into the lead. (5-3)


Note: The Standby time specification is an industry standard that is only intended to allow comparison of different mobile phones under the same circumstances. Power consumption in a standby state is strongly dependent on factors including: network, settings, location, movement, signal strength and cell traffic.


All of which brings us to the final round and the keen-eyed fight-watchers amongst you will have noticed that the result has already been decided. The Optimus 2X grabs yet another point thanks to GPS/A-GPS, DLNA content sharing, HD (720p) TV-out via HDMI, digital compass and a gyro-sensor.

In comparison, the iPhone 4 features GPS/A-GPS, a digital compass and a built-in 3-axis gyroscope. Game over for Apple’s smartphone. At least until the iPhone 5 comes along… (6-3)

The LG Optimus 2X wins!
