HTC One mini review: Meet Junior

Unboxing the One mini

The HTC One mini came with the exact same accessories as the HTC One - a compact charger with a detachable microUSB cable, a SIM ejector tool and a one-piece headset with spare tips. The headset is an in-ear design and has cool red accents and flat, tangle-resistant cables.

What's in the HTC One mini box

HTC One mini 360-degree spin

The HTC One mini measures 132 x 63.2 x 9.3 mm compared to 137.4 x 68.2 x 9.3 mm for the big HTC One. It doesn't sound like much of a difference, but you can really feel it when you hold the One mini in your hand, especially the width. It has also shed some weight and now weighs 122g (the One is 143g).

Design and build quality

The HTC One mini is little else, but a downscaled One on the outside - premium aluminum, with the solid feel of a unibody phone all whipped into an attractive design. While the 5" Butterfly S went with polycarbonate (perhaps due to weight considerations), the HTC One mini should earn as much praise for its design as the regular One did.

The mini also differs from the One in the polycarbonate strip that runs along the sides of the phone. The regular One has it too, but the one on the mini is thicker, covering the entire sides. We think this is an advantage - plastic can take a knock, while aluminum is more brittle (it dents and its paint peels off more easily when hit). We wish HTC had used the same matte plastic as on the One, this one is glossy and doesn't look quite as good.

Polycarbonate lines the sides of the One mini

Cutting down "only" 5mm from the height and width of the HTC One to make the mini might not sound like much, but that's because it's difficult to picture. In reality, the One mini feels noticeably more compact than its bigger siblings. It's roughly the size of last year's HTC One S, which is impressive as you are getting a pair of stereo speakers at the front.

Display

The screen is gorgeous - with 720p resolution it's not quite as sharp as the 1080p screen on the One, but at this size, spotting the difference takes some effort. It has great viewing angles and great colors too. Speaking of colors, the screen on our One mini has a warmer white balance than the screen on our HTC One.

The 4.3" 720p screen is great

Here are the two screens under a microscope:

HTC One mini • HTC One

The HTC One mini screen is very similar to that of the regular HTC One. The brightness is very high, higher than even the big One, let alone AMOLED screens. The contrast is amazing, making for one of the better viewing experiences on a smartphone.

The screen is fairly reflective though, which hurts its sunlight legibility. It's this reflectivity that brings down the sunlight lebibility noticably below the level set by the HTC One. It's not by much, but it's enough.

The Galaxy S4 mini screen brightness is not that high, but the lower reflectivity makes its display much easier to read out in the sun.

We find the One mini screen to be worthy of the One name, unlike the uninspiring qHD unit of the Samsung Galaxy S4 mini.
