“Best things come in small packages” is what the elders used to say, but ask Samsung or HTC about the proverb and they’ll cut you off with a “bigger is better” retort. Not Sony though, as the Japanese have just brought to light the highly anticipated Xperia Z1 mini.

Officially, because on the down low, the small yet uncompromising high-ender has been as transparent as glass for what feels like an eternity.

Technically, the miniaturized Z1 is called Z1 f SO-02F over in the Land of the Rising Sun, where it’s expected to debut on NTT DoCoMo in “late December”, but you can bet your asses Sony will follow this formal announcement with another one for an international flavor called simply Z1 mini. Fingers crossed for that to go down before CES 2014.

Like on their latest “full-sized” flagship, Sony’s designers haven’t really focused on the aesthetics part, so the Z1 f is not particularly fashionable, being actually quite chunky, as it tips the scales at 140 grams and measures 9.4 mm (ew) thick.

But it’s all for the greater good, as the 4.3-incher reportedly feels great in the hand while rocking the already customary water and dust protection options. And get this, the battery is a massive 2,300 mAh cell, or exactly the same size as the ticker inside the 4.7-inch HTC One. Chunkiness? Who cares about that?

Beneath the hood, the Z1 mini is really the textbook definition of cutting-edge technology, going all guns blazing against any and every high-end Android out and about, including its own big brother. Quad-core Snapdragon 800 CPU? Check. 2 gigs of RAM? Double check. 16 GB of storage with microSD support? You got it.

And what can I say about the 20.7 MP rear-facing camera with autofocus and LED flash to do it justice? That it’s outstanding both for photos and videos? That’s the understatement of the century.

As for the display, that’s probably the only department Sony has downsized compared with the Z1, lowering the resolution bar to “just” 1,280 x 720 pixels. But come on, you do realize Full HD would have been a complete waste on a screen that small, don’t you?
