Xiaomi Mi 6X Review: Perfect Mid-Ranger Supporting AI

Xiaomi has also managed to launch a Mi-series smartphone in face of the Mi MIX 2S. As you know, it comes with top-notch features including a Snapdragon 845 chip, 8GB of RAM, and tri-bezel-less screen. But this is a high-end model priced at 3299 yuan that isn’t affordable for many customers. To fill this gap and come in with a mid-range smartphone, the manufacturer held a conference at the Wuhan University Gymnasium and officially released its next-gen mid-ranger in face of the Xaiomi Mi 6X.

Last year, when the Xiaomi Mi 5X was out it grabbed the title of the best mid-range smartphone. That’s why the first Android One program smartphone of the Chinese Apple was based on it. The Xiaomi Mi 6X follows the current fashion and comes with a 5.99-inch Full HD 18:9 full-screen. It also sports a slim body at a 7.3mm thickness. At the same time, the Mi 6X uses an all-metal body with ‘invisible’ antenna ribbons and symmetrical design.

The Xiaomi Mi 6X is available in five color options including the Cherry Pink, Flame Red, Sand Gold, Glacier Blue, Black. So we can state the manufacturer has prepared color options for both men and women.

As for the configuration, the Xiaomi Mi 6X is the next bucket machine, which means there are no obvious shortcomings. The phone is packed with a Snapdragon 660 AIE chip, which is coupled with a 4/6GB of RAM and 64/128GB of internal storage. On the front, it carries a 20MP camera, while a 12+20MP dual-shooter is placed on the back. The phone runs on MIUI9 based on Android 8.1.

Finally, before we start getting acquainted with the key features of our protagonist, let’s take a quick look at the price tags:

  • 4+64GB – 1599 yuan
  • 6+64GB – 1799 yuan
  • 6+128GB – 1999 yuan

The SIM card slot is placed on the right side. It supports a dual-nano-SIM. As you guess, the slot doesn’t support a micro SD card expansion.

The back camera is prominent. So it’s better to use a protective cover to prevent the lens glass from being scratched.

Fortunately, the manufacturer has placed a soft transparent protective cover in the box.

The manufacturer has canceled the headphone jack. So there is only a USB Type-C interface on the bottom.

Inside the box, the Xiaomi Mi 6X has a 3.5mm audio jack to USB Type-C adapter.

However, the original charging head supports only 5V/2A power and there is no 18W fast charging head coming in the box. But the Xiaomi Mi 6X still supports fast charging.

Xiaomi Mi 6X Performance

When we say there is a handset powered by a Snapdragon 660 AIE, many people don’t understand what the difference is between the regular SND660 and the AI variant. But it’s obvious there are real differences between SoCs that use an independent AI unit and those that don’t.

After joining the artificial intelligence engine (AIE), the Snapdragon 660 AIE will perform better in terms of camera, gaming, and battery life. Of course, the hardware that includes CPU, GPU, baseband, process technology and other aspects remain the same. This simply means the Snapdragon 660 AIE uses a 14nm FinFET process node, 4×2.2GHz Kryo 260 large core + 4×1.8GHz Kryo small core design, built-in Adreno 512 GPU, and supports LPDDR4 memory as well as UFS2.1 flash memory. The baseband version is Cat.13. Not accidentally, it supports QC4.0 fast charging technology and comes with a dual 14-bit Spectra 160 ISP.

Second, it supports the full-screen gesture mode. It cancels the screen virtual keys and almost all the operations are performed by sliding, pushing up, and pulling down.

Another interesting option is the AI voice assistant called the ‘Little Love Student’. It covers over 100 voice operations. So most likely you won’t there won’t be an operation that you can’t implement via ‘words’. You can also use the AI intelligent translation function of the Xiaomi Mi 6X to translate menus, product descriptions, etc.

Xiaomi Mi 6X Camera

Unlike its predecessor that came with an OV12A10 + OV13880 sensors combination, it uses two Sony sensors. One of them is the Sony IMX486 sensor with a 12MP resolution, 1.25um unit pixel area, and f/1.75 large aperture. The second is the Sony IMX376 sensor with a 20MP resolution, 1.0um unit pixel area, and f/1.75 large aperture.
