On February 27, Barcelona time, Sony held a new product launch conference at MWC2017, and it released a number of new products.

The most eye-catching one is the Xperia XZ Premium with Snapdragon 835, which is also the first model with Snapdragon 835 in mass production.

Xperia XZ Premium uses the 5.5 inch LCD screen with 4K resolution that Sony is proud of, and the surface is made of Corning Gorilla 5th generation glass.

As early as Xperia Z5 Premium has adopted a 4K resolution screen. Today, the mainstream resolutions used by smart phones are still 2K and 1080P. After more than a year's accumulation, I believe Sony should have more understanding and optimization on the 4K screen.

Compared with the 4K screen, what makes users more excited is that Xperia XZ Premium has become the first model to use Snapdragon 835 processor. Snapdragon 835 is the latest flagship processor of Qualcomm. It has a combination of 4 x 2.45GHz large core+4 x 1.9GHz small core, 2MB L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2 L2. It integrates the world's first "gigabit level combination chip" X16 LTE, 2 x 2 802.11ac Wave 2 WiFi and Bluetooth 5, with a download speed of 1Gbps. In terms of image performance, the 835 is equipped with Adreno 540 GPU. In terms of 4K Ultra HD video, it supports HDR10, H.264 (AVC) and H.265 (HEVC) encoding, and supports 10 bit color and 3D audio.

In terms of operating memory, the machine finally stopped using the ancestral 3GB RAM and made a small upgrade, finally ushering in the 4GB era... In terms of built-in storage, it started at 64GB, supporting TF card expansion. However, Sony officials have not disclosed the ROM type for the time being. X Performance and XZ all use eMMC5.1 memory chips. It is unknown whether UFS 2.1 will be used on Xperia XZ Premium.

In terms of the rear camera, the machine uses a new 19 million pixel sensor, which is officially generated by Sony and can increase the processing speed by five times, and can support video recording at up to 960fps.

In terms of battery, it is equipped with 3230mAh built-in lithium-ion battery, supports QC3.0 charging standard, and uses USB Type-C interface.

In terms of "three prevention", as the ancestor of waterproof mobile phones in smart phones, it naturally supports the IP68 waterproof standard.

The three dimensions are 156 * 77 * 7.9mm, and the weight is 195g.

In addition to Xperia XZ Premium, Sony also released XZs, XA1 and XA1 Ultra. Among them, XZs continue to use Snapdragon 820 processor, with 4GB running memory and 32GB eMMC5.1 built-in storage. Yes, it still uses eMMC5.1. In terms of camera, it uses a new 19 million pixel sensor and also has 960fps of video recording. The battery is 2900mAh, supporting QC3.0.

The XA1 and XA1 Ultra use MediaTek P20 MT6757 processors. The XA1 uses a 720P 5-inch screen, 3GB+32GB configuration, and a battery capacity of 2300mAh. XA1 Ultra uses a 1080P 6-inch screen, 4GB+64GB configuration, and 2700mAh battery capacity. The rear camera uses the previous 23 million pixel camera, while the front camera is slightly different. The XA1 is 8 million pixels, and the XA1 Ultra uses 16 million pixels.
