HTC Desire HD vs iPhone 4

HTC's Desire HD and Apple's seminal iPhone 4 as contenders to fill the void in your pocket or handbag. Between them they represent the very pinnacle of smartphone development. With that in mind we've decided to let the two of them duke it out for the title of king of the heap.



Screen
HTC's Desire HD comes bristling with tech but the one thing that stands out is its amazing 4.3-inch LCD screen, capable of vivid colour rendition that will allow you to immerse yourself in your media on the hoof. At 3.2-inches the iPhone 4's screen is a little more stingy with the space, but the quality offered by the LED-backlit IPS 'retina display' is unparalleled. The detail on offer from the 640 x 960 pixel resolution screen is mind blowing and even though the Desire HD's display is something special it's bested here by something spectacular.

Optics
Apple heeded its critics when it was developing the iPhone 4 and included a top-quality 5-megapixel camera with autofocus and LED flash which is also capable of capturing 720P video. Similarly, the Desire HD offers 720P video capture and autofocus but behind this the device boasts a dual-LED flash and an 8-megapixel camera


Processing power
Apple's iPhone is a cutting edge piece of equipment and this is reflected in its specification. The device is powered by a 1GHz Apple A4 processor and 512MB RAM, allowing it to operate without the faintest suggestion of lag.  Again, HTC's Desire HD takes what the iPhone 4 offers and ups the ante, boasting  a 1GHz Qualcomm Snapdragon CPU and 768MB RAM! Both devices use their muscles wisely too, with seamless transitions between apps and menus and smooth gaming .

Operating System
Google's Android OS is enjoying huge success at present and with good reason. It's powerful, efficient and damned easy to use and the fact that it's based on good, wholesome open source ideals makes it a very palatable offering for those with a conscience. Apple's software, iOS, is the one to beat though, and it's easy to see why when you pick up an iPhone 4. iOS is simplicity personified.

App Support
Apple's App Store recently saw its 1 billionth download, and its huge catalogue of over 300,000 apps has something to offer anyone, no matter how discerning. A good deal of the content available is free and you can also download TV shows and movies to your device through the service.

We were hoping for a definitive conclusion to this battle for smartphone superiority but both devices are brimming with virtues, leading us to a draw, albeit a stirring one.  At this stage, if you are looking for the very best device available you won't go far wrong with either of these amazing pieces of technology.

iPhone 4 vs Samsung Galaxy S

We thought it might be fun to see just how competitive high-end Android devices have become by pitting one of the best, the Samsung Galaxy S, against Apple's perennial favourite.

Display
We thought we'd launch out of the blocks with the hardest criteria to judge, that of screen quality. Apple's iPhone 4 boasts a hugely impressive 3.5-inch screen dubbed the Retina Display, which features a groundbreaking 326ppi (pixels per inch), making what you see on the screen as near to true life as you're going to get.

The Galaxy S may not be able to rival the iPhone for pixel density but it can certainly hold its own, with a sharp 4-inch Super-AMOLED screen capable of the deepest blacks and the most vivid colours .

Drive Train
Internally both of these devices are cutting edge. Samsung's Galaxy S is driven by a powerful 1GHz Hummingbird chipset which includes a PowerVR GPU as well as 512MB RAM, allowing the device to run multiple apps without any discernible lag. The iPhone is similarly spec'd, with a 1GHz Apple A4 CPU and 512MB RAM taking care of the donkey work, allowing the iPhone's slick UI and apps to run unhindered.

With similar hardware it's tough to separate the two devices, though they both use what they're given very differently.

Optics
Samsung Galaxy S  5-megapixel camera is capable of producing impressive shots and the support for 720P video capture only adds to the Galaxy's charm. As charming as the Galaxy S is, it can't measure up against the iPhone's 5-megapixel snapper though, which features LED flash, autofocus and also captures 720P movies. While both devices offer cameras that are similar on paper, the iPhone's faster shutter speed and slicker user interface shine through, giving Apple's baby its first win of the contest.





Operating System
Apple's iOS has been the benchmark that other operating systems measure themselves by for some time and it's so easy to see why. With sharp, good-looking graphics and intuitive controls, iOS is everything you want from a mobile OS. It allows you to get things done with minimum of fuss, supports tons of apps and doesn't scrimp on the eye-candy.

The Samsung Galaxy S runs version 2.2 (Froyo) of Google's Android OS and it's a masterpiece of complexity distilled into something amazingly usable. Android affords you all the usability of Apple's masterful iOS but with the added bonus of being based on open source ideals, meaning that you are able to examine and change the very core tenets of the operating system to your own specification, if you're so inclined


Future Proofing
Apple has the future covered. The iPhone 4 receives updates from the boffins at Cupertino fairly regularly, patching flaws and adding features, and you can expect to receive the newest version of iOS as and when it rolls off the production line.

Samsung's Galaxy S runs a custom UI over the top of Google's Android platform and although this augment's the user experience for the better it somewhat hinders the device receiving updates. The device shipped with version 2.1 of Android, that was recently upgraded to version 2.2 and users can expect to receive version 2.3 but the job of tailoring the custom TouchWiz UI means that it won't be as brisk as the iPhone 4, or indeed some of its purer competitors.

Samsung's contender has really taken it to Apple, but the iPhone 4 just snagged it with its Retina Display – something the Galaxy S simply cannot compete with.
