It's like a Z3, but smaller
Alongside the Xperia Z3, today at IFA 2014, Sony also unveiled a new, smaller 'flagship' phone. The Xperia Z3 Compact is part of Sony's flagship Z3 mobile lineup and in pretty much every way possible it's like the bigger Z3. It looks like the Z3, runs the exact same software as the Z3 and has a lot of the same hardware as the Z3. It's a smaller Z3.
It has the same 2.5GHz Qualcomm Snapdragon 801 as its bigger brother but is down on the RAM with 2GB here. It shares the 20.7MP rear camera, the same overall design with tempered glass panels, the same software, the same new camera features and PS4 remote play capability. It's also IP65 and IP68 rated for dust and water resistance like the Z3.
It differs in the display specs with a 4.6-inch 720p panel, though at that size it's still pretty sharp and it's plenty bright and vibrant enough. The aluminum frame of the Z3 has been lost in favor of what Sony calls a "liquid reflection frame." It also comes in some different colors with an orange and green version to accompany the more regular black and white.
But you know what? It's a Sony Xperia Z3 in a smaller form factor. And that's just fine. Because once again Sony has proved that making a mini version of its high-end devices doesn't mean you need to cheap out and cut back on the hardware.
