TAIWANESE PHONE MAKER HTC's One X was one of our favourite Android smartphones when HTC released it midway through 2012.
However since then the company has launched its upgraded One X+ smartphone.
Living up to its name, the One X+ features an improved quad-core processor that promises to make it one of the fastest smartphones presently available.
For this reason, when the device fell into our hands we couldn't resist the opportunity to see how the One X+ matches up against the leaders in the smartphone market, the Samsung Galaxy S3 and Apple iPhone 5.
Design and build
The HTC One X, Galaxy S3 and iPhone 5 each represent the design philosophies of their makers, which means it's fairly easy to tell them apart.
For example, the One X+ has a more utilitarian design than the Galaxy S3 and iPhone 5, reflecting HTC's ongoing focus on functionality over visual allure.
The One X+ has a minimalist design, featuring a unibody monotone case. Its only noticeable external features are the rear facing camera and three capacitive buttons on the front, which are highlighted with red outlines.
By comparison, the iPhone 5 and Samsung Galaxy S3 boast far flashier designs, revealing the desires of these two companies to each market their device as the world's number one luxury smartphone.
Despite this, the devices look very different, with the Galaxy S3 being far more curvy than the angular iPhone 5. The only design similarity between the Galaxy S3 and the iPhone is that both have metal sides.
The iPhone 5 is the smallest and lightest, measuring 124x59x7.6mm and weighing 112g.
The larger Galaxy S3 and One X+ by comparison measure 134x70x8.9mm and 137x71x8.6mm and weigh 135g and 133g, respectively.
Users accustomed to smaller handsets will likely find the iPhone 5 more comfortable to hold in the hand, while people used to larger phones will likely prefer the One X+ or Galaxy S3.
However, the One X+ seems to be the most solidly built, with its chassis feeling like it could take significantly more punishment than the iPhone 5 and Galaxy S3, which both have cases that are susceptible to scratching and cracking.
We found that the iPhone 5 was slightly sturdier than the Galaxy S3. This is because the Samsung model's removable back plate feels flimsy, so much so that we winced whenever we removed it, fearing it would snap.
Winner: The sturdy build of the One X+ trumps the flashy iPhone and Galaxy S3.
All three smartphones boast brilliantly bright and crisp displays, though in our opinion, the iPhone 5 has the best display.
Apple has given the iPhone 5 an impressive 4in 1136x640 resolution 326ppi screen that features the firm's Retina display technology.
We found that while smaller than the Galaxy S3's and One X+'s 4.7in and 4.8in displays and actually boasting a slightly lower pixels per inch (ppi) count than the impressive 720x1280 330ppi Super AMOLED display of the Samsung device, the iPhone 5 display just looked better.
