The HTC One mini is a downsized version version of the HTC One in both size and specifications.
The One mini looks almost identical to the One. It has the same aluminium design, the same dual, front-facing speakers, and the same UltraPixel camera on the back.
The One mini measures 9.4mm thick but is smaller in both width and height than the original One.
The One mini has a smaller 4.3in LCD3 screen with 720p resolution which is expected given the cut down size.
However, it also has downgraded specifications. It runs a dual-core 1.4GHz Snapdragon 400 processor compared to the One's quad-core 1.7GHz Snapdragon 600 CPU, has 1GB of RAM compared to 2GB, and comes with 16GB of internal memory instead of the One's 32GB.
The One Mini also misses out on NFC connectivity, an Infrared port, and optical image stabilisation (OIS).
The One Mini runs the same Android software (4.2 Jelly Bean) as the One. It also comes with HTC's Sense 5 user interface, which includes the BlinkFeed home screen.
BlinkFeed looks like a cross between Windows Phone 8 and the Flipboard media aggregation app. The alternative home screen pulls in content from a variety of pre-selected sources including your social media accounts.
Although it lacks optical image stabilisation, the HTC One mini's rear camera is identical to the original One otherwise.
The 4-megapixel sensor uses enlarged pixels that the company says can absorb up to three times more light than those inside "most leading 13-megapixel phone cameras."
The HTC One mini has a non-removable 1800mAh battery and will be 4G compatible in Australia on the 1800MHz network band.
There's no word yet on an official Australian release date or pricing, but the HTC One mini will launch in "selected markets" from August and will be rolled out globally from September.
