This is as big as it can get, at least as of today. After Apple’s recent announcement of the latest iPhone 5, the tech world is abuzz with comparisons and analysis of how this new iPhone would compare with two of the other heavyweight mobile phones launched a while back – the Samsung Galaxy S3 and the HTC One X. We bring you an in-depth look into what’s on the inside of these phones so that you can pick the phone that’s right for you.

Operating System: The very first in the list of comparison would of course be the operating system – while the Samsung Galaxy S3 and HTC One X both come with Android 4.0, the iPhone 5 would have the latest iOS 6 installed in it. Samsung has already announced an upgrade to Android 4.1 or Jelly Bean in the near future, while we are yet to hear from HTC on this one.

Dimensions: This is where it starts to get more interesting. In this category, Samsung Galaxy S3 is the definite winner, boasting of a 4.8 inch large AMOLED screen, while the HTC One X comes a close second with a 4.7 inch screen. What’s disappointing about the iPhone 5 is that it will feature only a 4 inch screen, even though its resolution is much better than the other two contenders and also has Retina technology.

Tech Specs: All these phones spew a ton of power for sure. Samsung has put in a 1.4 GHz quad core processor in the S3, the One X has a 1.5 GHz Nvidia Tegra 3 quad core processor, and the iPhone 5 will have a brand new A6 processor based on dual core ARM Cortex A-15 architecture and is expected to be at least twice as better as the A5.

Camera: With better technology, we are getting increasingly dependent on our smartphones for our camera needs. And this is one area where all these 3 models have common ground – an 8MP rear camera. While the iPhone 5 features a smaller iSight camera in the front, the S3 is equipped with a 1.9MP front-facing camera, and the One X has a corresponding 1.3MP camera that can be used while making video calls or clicking self shots.

The Galaxy S3 and One X have been around in the market for some time now, and so have already got a jumpstart over the iPhone 5, which is expected to start shipping by September 21st. Let’s see if Apple can change the balance and sway more customers towards itself like the previous models have managed to do in the past.
