Design and display
Huawei has hopped on the glass phone bandwagon, but it's not a functional change a la Apple—this phone does not support wireless charging. The back panel is glass just for aesthetic reasons. I'm not necessarily a fan of glass phones, but this one does look pretty nice (except for the fingerprints it picks up as soon as you touch it). The back is a single piece of glass that's curved on all four sides. There's also a strip of reflective foil under the glass in a strip that surrounds the cameras.
The regular Mate 10 has a 1440p LCD, but this phone uses an entirely different display; it's a different shape and resolution. The front of the Mate 10 Pro has slim bezels on all sides of the new 6-inch 18:9 OLED panel. The corners aren't rounded off like a lot of other phones, but that doesn't affect usability. The display still dominates the front of the phone. There's barely enough space on the bottom bezel to squeeze in the Huawei logo. They found a way, though.
The OLED has a resolution of 2160x1080. So, it's a slightly taller 1080p. The resolution is lower than the regular Mate 10, but it is OLED. As we've all come to know, OLED quality varies quite a bit. This is a good overall panel with only minor color shifting at angles, and the colors are calibrated to be vibrant out of the box. There's a more natural "normal" mode in settings. I'm not sure if it's sRGB, but it looks close.
Huawei is again using a dual camera array on this year's phone. The Mate 10 Pro has a 20MP monochrome sensor and a 12MP RGB sensor. There's optical stabilization only on the 12MP sensor, but both have a respectable f/1.6 aperture. By default, the camera takes 12MP images. However, the camera app blends data from the RGB and monochrome sensors when you snap a photo. That means you can take 20MP shots with color. The drawback is that some of the camera's special features don't work in that mode. In 12MP mode, you have the option of 2x zoom "lossless" zoom. It uses the higher-resolution 20MP sensor to essentially zoom and crop to 12MP.
I'm extremely impressed with the quality of photos from the Mate 10 Pro. It excels at taking quick snapshots in moderate light, which is what most people are doing with their phone cameras. In most situations, I'd place it up there with Samsung and Google as one of the best smartphone cameras I've ever used. It pulls in a lot of light to make photos in dim settings usable, and captures are fast enough that you don't get too much blurriness. The OIS on the 12MP sensor helps there. White balance looks very accurate, and focusing is almost Samsung-fast, too.
Battery and performance
Most phones are shipping with a chip from Qualcomm or MediaTek, but Huawei uses its own Kirin SoCs in many phones. The Mate 10 and Mate 10 Pro debut the new Kirin 970, which consists of four ARM Cortex A73 cores at 2.36GHz and four ARM Cortex A53 cores at 1.8GHz. There's also a Mali G72 GPU with 12 cores. These are all reference designs, but the neural processing unit (NPU) is a completely custom core intended for machine learning and neural network applications. Since this is a new chip, I've got a few benchmarks below.
