HTC announced a smaller version of its latest flagship smartphone, HTC One (M8), giving it the somewhat unwieldy moniker of One Mini 2.

While HTC is obviously keen to keep ‘One’ as its premium smartphone brand, this has led to some rather strange naming conventions. This year’s flagship One has picked up the seemingly inexplicable (M8) tag to differentiate it from last year’s device, while last year’s has gained a new model name (M7) – which was never used during its first twelve months on sale.

With its ‘Mini’ devices, HTC is following a similar path to Samsung and LG, in that it actually features a significantly different specification than its parent device. Contrastingly, Sony’s Xperia Z1 Compact shares much of its innards with the Xperia Z1, excluding obviously the screen.

With the HTC devices, the obvious difference comes in screen size: 4.5-inch 720p HD rather than 5-inch 1080p HD for the bigger sibling.

But One Mini 2 features a number of other changes: it has a 1.2GHz quadcore processor and 1GB of RAM, compared with 2.3GHz and 2GB of RAM for the bigger device, meaning in this regard it is less ‘premium’ than its sibling.

It has 16GB of storage but also includes a MicroSD slot, to provide additional capacity.

In terms of appearance, it is said to feature “the same breakthrough design” as last year’s HTC One (M7), alongside “the smoothly curved back and brushed gunmetal grey finish” of the current HTC One (M8).

It will also be available in silver and gold versions.

HTC also highlighted its 5MP front-facing camera, meaning that “high-quality selfies are guaranteed.” It has a traditional 13MP main camera rather than using the “ultrapixel”-style camera used in One (M8), and lacks some of the imaging features of the bigger smartphone.

Other features include BoomSound audio – it features the same amplifier as One (M8) – and BlinkFeed content aggregating home screen.

The device will be available in EMEA and Asia from June 2014.
