In less than just two months after introducing the Xperia XZ2 at the Mobile World Congress, Sony is again back with the Xperia XZ2 Premium. It retains the overall similar design just like the XZ2, a departure from the past phones of Sony, but upgrades the display, battery, camera, and other specifications. The XZ2 Premium would be available starting this summer. The pricing is yet to be announced, but certainly, it would be expensive. The XZ2 runs 800 dollars unlocked, so the users are probably looking at a 900 dollars or 1,000 dollars phone here.

The company is putting a 5.8-inch 4K display in the XZ2 Premium, an enhancement over the 5.7-inch Full HD+ (1080 x 2160) screen on the regular XZ2. The HDR video is supported by both of them. When the users would be watching videos, playing games, or listening to music, they would experience the new vibration system that debuted in the XZ2; it is meant to extend rumble feedback to match whatever is happening on the screen.

According to Sony, the biggest upgrade here is the camera. The XZ2 Premium possesses two of them around back. Rather than adding a telephoto/zoom lens such as Samsung, Apple, and OnePlus, Sony is splitting the image capture in between a 12-megapixel monochrome and one 19-megapixel color sensor.

It is an approach that several other Android makers including Huawei have taken up. The point where Sony is trying to best everyone and stand out is, in the ISO performance. When shooting stills, the XZ2 Premium could reach a maximum ISO of 51,200. The videos go as high as 12,800. Normally anything one would get at those numbers on a smartphone would appear like grainy garbage, but Sony claims that its “AUBE fusion image signal processor” could combine the data from both the sensors, reduce noise, and optimize for low light so that the users get usable results. As to how it actually pans out in the real world use is to be seen but the company says this lets for ultra-low-light capture that earlier was only seen in the interchangeable lens cameras.

The dual camera system would even have a portrait feature and would allow users shoot using only the monochrome sensor for detailed black, crisp, and white shots. These two features would not be on the XZ2 Premium at the launch and would arrive in a Q3 software update. The Premium, like the XZ2, could record 960fps slow-mo video at 1080p resolution, an enhancement over the 720p limitation on Samsung’s Galaxy S9.

The other improvements on the XZ2 Premium involve battery capacity, RAM, and a sharper front-facing camera. Sony is putting 6GB of RAM in the XZ2 Premium versus the 4GB in the standard XZ2. Unlike the 5MP front camera of the XZ2, the XZ2 Premium has a 13-megapixel selfie camera. The battery inside the XZ2 Premium is 3540mAh versus the 3180mAh battery in the standard model. That may not necessarily imply a superior battery life, however, as the XZ2 Premium has to power a much higher-resolution display. The other key specifications remain the same as that on the XZ2. Both the phones have a Snapdragon 845 processor inside and ship with Android 8.0 Oreo.
