Xiaomi is at it again, and this time it they came with a big bang. I am talking about the new Xiaomi Mi 6X. This smartphone is a real value for money. With its unique features coupled with its irresistible cheap price, this phone is the talk of town.
The Xiaomi Mi 6X retains the design language of its predecessor, but there have been a few additions on top. Like the Redmi Note 5 Pro and new Mi Mix 2S, the Xiaomi Mi 6X also has a vertical iPhone X-like dual-camera design.
At 7.3mm the Mi 6X looks sleek and shares its resemblance with the Mi A1 from the back. But the front has seen major changes, the 5.5-inch 16:9 display has been upgraded to a new 18:9 FHD+ display measuring 5.99-inches. It results in minimal bezels and more screen space.
Announced: 2018, July
Status : Available. Released 2018, July
The Xiaomi Mi 6X (Mi A2) is powered by the Qualcomm’s Snapdragon 660. It has a 3010-mAh battery and features support for Quick Charge 3.0. Furthermore, the mid-range smartphone comes with a 5.99-inch Full HD+ display, a dual-camera with 12 and 20 MP sensors, a fast lens with an f/1.75 aperture as well as a USB Type-C port. The device can be unlocked via FaceUnlock or through a fingerprint scanner. We have already described the differences between the Mi 6X (Mi A2) and its predecessor in a separate article.
The top-end model of the Mi 6X (Mi A2) features 128 GB of internal storage and 6 GB of RAM. It costs about 260 Euros ($305) without shipping from China. Our review device comes with 64 of storage space and 6 GB of RAM and costs about 235 Euros ($276). The base model of the Mi 6X (Mi A2) costs 210 Euros ($246).
Body – the Mi 6X offers a great build quality
The metal case of the Xiaomi Mi 6X (Mi A2) comes in the following color schemes: Black, Gold, Blue, Red and Pink. There is a special edition of the Mi 6X (Hatsune Miku) for manga fans, which has a “turquoise” color scheme.
The entire front of the Mi 6X (Mi A2) is covered with scratch-resistant 2.5-D glass. The glass is slightly rounded at the point where it meets with the metal frame. The IPS display has small bezels. However, the bottom bezel and the top bezel are really big when compared to the current high-end smartphones. This is why the Mi 6X has a screen-to-body ratio of only 78%.
The “Picture Perfect Dual Camera” on the back of the Mi 6X protrudes considerably from the case. Both the look and the feel of the matte aluminum finish are great. The smartphone is also very “grippy”. The case is very rigid as well. The Mi 6X is comfortable to hold in the hand, thanks to its thickness of 7 mm (~0.3 in).
The hardware buttons such as the power button and the volume rocker impress with their quality. The buttons are firmly set and do not wobble. The actuation point is also very clear.
With 64 GB of internal eMMC memory, the Xiaomi Mi 6X offers a sufficient amount of storage space. Straight out of the box, only 50 GB of storage is available to the user. Those who need more storage space should get the 128 GB version. The storage capacity of the Xiaomi Mi 6X cannot be expanded with the help of an SD card.
As usual, Xiaomi uses its own proprietary launcher MiUI (ROM version 9.5.11 Stable). The smartphone runs Android 8.1. The security patches were last updated in May 2018.
The intergraded Wi-Fi module supports the IEEE-802.11 standards a/b/g/n/ac. In combination with our reference-grade router, the Linksys EA8500, the Xiaomi Mi 6X achieves good transfer rates of 307 MBit/s for upload and 247 MBit/s for download. In close proximity to the router (Telekom Speedport, W921V), we measured a signal attenuation of -38 dBm, which is rather high.
The Mi 6X can use two nano-SIM cards at the same time. The Mi 6X’s LTE modem operates at LTE Category 12 speeds of up to 600 MB/s. This applies to both SIM card slots. However, the Mi 6X is not going to operate at such speeds in rural areas of Germany, because it does not support LTE band 20. The international version of the Mi 6X, the Mi A2, is going to support LTE band 20, which means that it is going to cover the 800 MHz frequency range.
For short-distance communication, the Mi 6X features Bluetooth 5.0. However, it does not support NFC.
The call quality is on a good level. We did not observe any call drops or reception problems with the Xiaomi Mi 6X. The voice on the other end of the line is very clear and easy to understand. Our call partner also had no trouble understanding what was said during the call. During video calls, the built-in microphones help ensure a decent call quality.
Cameras: dual-camera is very good
The Mi 6X features a 12 MP and 20 MP dual-camera module on the back. The 12 MP camera comes from Sony (IMX486) and has an f/1.75 aperture and a pixel size of 1.25 µm. For night shots, there is a 20 MP sensor (Sony IMX376) with a pixel size of 2 µm, which takes in more light thanks to its bigger pixels. It has an identical aperture of f/1.75. Dual-camera systems offer the ability to dynamically adjust the depth of field to produce images with a Bokeh effect.
The Xiaomi Mi 6X (Mi A2) follows the trend of building AI capabilities into smartphones. The Xiaomi Mi 6X’s camera boasts support for object and scene recognition, both when recording video and when taking photos. It also uses AI for creating the Bokeh effect.
The Xiaomi Mi 6X relies on software image stabilization. It does not feature support for optical image stabilization.
The 20 MP front-facing camera also offers a good picture quality. However, it does not feature autofocus, which means that the sharpness of the photos is not always optimal. It can shoot video in Full HD (1920×1080) at 30 FPS.
Accessories and Warranty
The box contains the quick start guide, a 10-watt charger (5V, 2 A), a USB cable, a protective case and a USB Type-C to 3.5-mm audio jack adapter.
There are no headphones in the box. TradingShenzhen also put an EU-compliant power plug in the box. The smartphone does not ship with this plug included.The smartphone comes with a 12-month warranty.
Performance – Qualcomm Snapdragon 660 offers more than enough power
The Xiaomi Mi 6X relies on a Qualcomm chip from the 600 series. The Snapdragon 660 has eight Kryo 260 cores. Four of these cores run at 2.2 GHz (high-performance cores) and the other four (energy-efficient cores) at 1.8 GHz. The Adreno 512 does a great job. In our benchmark suite, the Mi 6X dominates the rest of the mid-range competition when it comes to the SoC performance.
In day-to-day use, the Xiaomi Mi 6X is very responsive. Animations are smooth and stuttering or lags are imperceivable.
