Xiaomi Mix 2 has a bigger screen than Sharp S2, and did not imitate the Sharp S2’s special-shaped full-screen design, the SIM ejector position is not noticeable but daring enough to challenge the design of “the father of LCD”.
On the other hand, in order to fully portray the Xiaomi Mi Mix2 full-screen technology compared to Samsung, Apple’s flagship products, Lei in the conference cited a friend’s hand drawing, which portrayed Xiaomi Mix 2 with chin beard, Samsung Galaxy S8 with hairy forehead and chin, and the iPhone 8 with hairy face edge. Lei Jun citation of this more or less hinted that its flagship design more in line with the full-screen definition.

Xiaomi Mix was a significance move and was a forerunner, after all, at its launch it was the only concept device. However, there are shortcomings like size large body weight, poor fingerprint unlock experience, poor quality of the call, and average photo quality (as seen on 1000 Yuan phones).
Xiaomi Mix 2 is a key breakthrough overcoming these shortcomings, but has a strong performance, ultra-narrow frame and ultra-high screen resolution and other improvements. Similar to the three-stage metal and one-piece metal body, ceramic body phones can also be categorized as full ceramic, four-surface ceramic and Unibody full-ceramic body accordingly to the manufacturing process.
Xiaomi Mix and Xiaomi Mix 2 full-ceramic version has ceramic frames and back, but Xiaomi Mix 2 full-frame has both the frame and back integrated as single mold.

The 18:9 screen is more suitable for MOBA games

Xiaomi MIX 2 can get a wider range of combat horizons

Overall, Xiaomi MIX 2 in appearance is more convergent and suitable for mass production, when compared to its predecessor. It does not modify the overall visual experience at the same time, it is more in line with market demand, that an 18: 9 screen compared to competing products that 16: 9 screen to get a broader field of vision.

3. Camera: The premium level are thoroughly reduced with the full screen

With Xiaomi Mix 2, some of the camera parameters were adjusted when compared to Xiaomi Mix, the poor 16 MP CMOS camera of its predecessor is replaced with higher quality IMX386, and at the same time the introduction of optical image stabilization technology.
Also, PDAF technology, F2.0 aperture, dual-color temperature flash and recording 4K video were incorporated into Xiaomi Mix 2.
The Xiaomi Mix 2 can generate three different aspect ratio of pictures, which are more than compared with other models even with its predecessor Xiaomi Mix.

This landscape pictures at low light seems to match both the models equally, and depth of the field is very good. But as the light further declines into the night, Xiaomi Mix 2 looks better due to good white light balance. Both models shows some strange phenomenon, with Xiaomi Mix 2 shows a slight tint of yellow, and Xiaomi Mix shows a slight tint of red in these low light shots at night.

Xiaomi MIX (left) vs Xiaomi MIX 2 (right)

I took the night photos with EXIF parameters, found that almost the same for both the model. So exposure is very similar. Even with optical image stabilization of Xiaomi Mix 2 did not level with Xiaomi MIX brightness or purity in nighttime photo shots.

HDR Off: Xiaomi MIX (left) vs Xiaomi MIX 2 (right)

HDR On: Xiaomi MIX (left) vs Xiaomi MIX 2 (right)

The Xiaomi Mix low light HDR effect is higher than that of Xiaomi MIX 2, though it sacrifices brightness detail for rich details in dark. The image composition speed is similar to the day, the Xiaomi Mix composed it in 1seconds, while Xiaomi Mix 2 took about 2 seconds.

Xiaomi MIX (left) vs Xiaomi MIX 2 (right)

Under extreme low light, the Xiaomi Mix 2 with optical stabilization has a higher brightness, but the resolution is similar to the Xiaomi Mix.
The brightness, purity and resolution of the Xiaomi Mix 2 in the nightscape are not close to the Xiaomi MIX. Xiaomi Mix 2’s Sanpdragon 835 gives better HDR synthetic speed, but image quality seems to be less than Snapdragon 831 powered Xiaomi MIX.

4 Selfies

Intelligent Beauty Mode: Xiaomi Mix (left) vs Xiaomi MIX 2 (right)

Advanced Beauty Mode: Xiaomi Mix (left) vs Xiaomi MIX 2 (right)

The 2017 models of Xiaomi phone’s selfie are getting better and better. Though Xiaomi Mix 2 has a 5 MP front camera, but the imaging performance is relatively more natural and eye-pleasing, adding more the benefits that comes with AI enabled beauty modes.
Xiaomi Mix 2’s camera performance is way better compared Xiaomi Mix, moreover Xiaomi Mix 2 has IMX386 that provides good quality photos, and camera UI is easier adjustment features.
First, though Xiaomi Mix has come down in terms of pixel to 12 MP, the resolution power is better than 16 MP camera of Xiaomi Mix.
Secondly, the white balance and color saturation, hair color tendency seems to be more realistic on Xiaomi Mix 2, with added better performance, it is way better than Xiaomi Mix.
Moreover with the optical stabilization technology of the Xiaomi Mix 2 outwits Xiaomi Mix in low light / night photo performance. In addition, Xiaomi Mix 2 provides better brightness even for a very poor lighted subject.
However, there isn’t much gap between Xiaomi Mix 2 and Xiaomi Mix when it comes to day time /night time HDR effects, and the Snapdragon 835 in Xiaomi Mix 2 seems to be slower than the Snapdragon 815 in Xiaomi Mix, which seems to be bit odd.
Finally, to Selfies. Xiaomi seems to have put the experience of Xiaomi 5x and Xiaomi 6 into Xiaomi Mix 2 selfie algorithm, thus produces better selfies, even though it has the same 5 MP camera that of the Xiaomi Mix.

Four: performance: Sanpdragon 835 plus 8GB memory, Xiaomi Mix 2 is the flagship of the year for Xiaomi without any doubt.

In the first half of this year, Xiaomi 6 did not beat the expectations of many supporters, in addition to the dual-camera, other configuration were not top notch to make it as Xiaomi’s flagship product of 2017.
In the second of this year, the new new Snapdragon 835 powered Xiaomi Mix 2 was launched. Thought, it does not have dual-camera design of Xiaomi 6, Xiaomi Mix is the flagship for this year and is the first 8GB RAM mobile phone.
Next, I am writing about the performance the phone when tested with AnTuTu, Geekbench, Gfxbench, Androbench and “Glory of the King”. I used the Xiaomi Mix 2 (6GB RAM Edition) for these tests.

AnTuTu Test

Last year, Snapdragon 821 was the talk of the mobile world finding its place in almost all top notch models. Now, with Snapgradon 835, Xiaomi Mix 2 scores better points than its predecessor.
The performance score clearly establishes the winner without any doubt.
Note: The Xiaomi Mi MIX 2’s 8GB variant can be compared only with the Nubia Z17 and OnePlus 5, as only they come with identical features.

2, Geekbench test

Geekbench is a cross-platform CPU performance testing tools that can accurately reflect the CPU single core performance or multiple core performance. Test Load simulation Real-life application design, the result is more meaningful, also can measure GPU graphics card computing performance.
Single core performance can reflect the design of the CPU architecture, the operating frequency of the high-low. Multi-core performance can reflect the efficiency of multiple CPU cores at the same time at work.

Though XiaomiMix 2 and Xiaomi Mix flat has similar scores for random reads and random writes, Xiaomi Mix 2 outwits Xiaomi Mix in sequential workloads.

Five – Battery life: Xiaomi Mix 2 – Stronger battery, less power

If the camera and performance is Xiaomi Mix 2, compared to Xiaomi Mix in technical terms, then the predecessor seems to be advantageous, as Xiaomi Mix 2 sees a reduction of 1000mAh. But these numbers don’t always mean everything.
To fully test the battery life and performance of Xiaomi Mix 2, we have three test items, “King glory” game, online video playback, and PCMARK battery life.

1 Game Test

We used Xiaomi 2 off power mode, and run the game in performance priority mode, insert headphones, in automatic brightness, played the “King glory” for half an hour, and observe the power consumption.

Xiaomi Mix 2 with 98% battery at the beginning of the test

Xiaomi Mix 2 with 91% battery at the end of the test

Xiaomi Mix with 62% battery at the beginning of the test

Xiaomi Mix with 53% battery at the beginning of the test

Xiaomi Mix 2 uses 10 nm Snapdragon 835 which improves power consumption control, when compared to compared with 14 nm Snapdragon 820/821 used in Xiaomi Mix. We we played the game more for 30 minutes after the battery charge fell by only 7%, and the frame rate performance is still outstanding, in other words, has an high energy efficiency ratio.
Xiaomi Mix battery is also down 9%, though it has a higher capacity batter, produces the same power drain has Xiaomi Mix 2, thus proving that the Snapdragon 835 is a great success.
It is worth mentioning that Xiaomi Mix 2 that this result is same when tested with Samsung Note 6 which has a 4000 mah batter. Xiaomi Mix 2 performance is outstanding, perhaps the small battery seems to be helping it.

2. Video Test

We used Bilibili App to watch an hour online video to observe the change in battery power.

Xiaomi Mix 2 with 85% battery power at the beginning of the video test

Xiaomi Mix 2 with 76% battery power at the end of the video test

Xiaomi Mix with 81% battery power at the beginning of the video test

Xiaomi Mix with 74% battery power at the end of the video test

After watching the video for an hour, Xiaomi Mix 2 power slipped 9%, and its predecessor Xiaomi Mix by 7%, so Xiaomi Mix consumed 2% more power compared to its predecessor, not a bad one considering it has 1000mAh battery capacity.

3. PCMark Battery life test

Xiaomi Mix 2’s PCMark batter life test results

Overall, Xiaomi Mix 2 of the life performance in the PCMark database is commendable. When compared to other Snapdragon 835 models, Xiaomi 6 seems to have better score, but this one is still better than Samsung’s Galaxy S8 series.

4. Battery Charging test

Xiaomi Mix 2 is allowed to charge from 0% to 100% after a reboot, with no SIM, Wi-Fi On, using the standard 18W fast charger.

Xiaomi Mix 2 battery charge performance

18W quick charge took about 40 minutes to get Xiaomi Mix 2 charged 70% and about 85 minutes to get fully charged, which seems to be a standard numbers for flagship models.

Six, Summary: Reborn this year, the most worthy of the flagship millet flagship

As the flagship of the second half of the year, the Xiaomi Mix 2 has most powerful configuration of Xiaomi for 2017. Although it does not feature a dual camera, it has 8GB of RAM and a full screen and Unibody frame.
Compared to the Xiaomi Mix, the photo quality and camera performance are the biggest improvement. The Xiaomi Mix 2 is clearly positing itself as an all-balanced flagship, especially for those who hate to optimized dual cameras and like are the “conscience” single camera consumers. Appearance, Xiaomi Mix 2 undoubtedly represents the highest level of technology design among the Xiaomi mobile phone. Compared to Xiaomi Mix, it has a smaller screen, better resolution, lighter, thinner, and has visually appealing experience, whether it is four curved ceramic body or Unibody all-ceramic body. The friendly street metallic mode is obviously little different.
In addition, 18:9 of the screen of Xiaomi Mix 2 is more refreshing when compared to the ordinary 16:9-screen mobile phone. The extra space gives a wider version of “Glory of the King”, and seize the opportunity to torture enemy.
Camera of Xiaomi Mix 2 is a big plus when compared to predecessor except for the night or low light pictures. Specifically, Xiaomi Mix 2 has rich experience with IMX386 technology, making white balance more accurate and color saturationmorepleasing.
Compared to the 16 MP CMOS of the Xiaomi Mix, the 12 MP IMX386 has an better resolution, whether it’s day or indoor, both center details and edge details.
Although the 5 MP front camera seems to beconventional, the Xiaomi Mix 2 has various Selfie modes to fine-tune the portrait giving a better Selfie experience, and pictures quality is better than before.
In terms of system, the Xiaomi Mix 2 with Sanpdragon 835 is better than Xiaomi Mix and Xiaomi 6. In addition, a stable frame rate performance with 18:9 screens makes the gaming experience even better, though a high frame rate would have made the phone closer to perfection.
Compared to 20nm Snapdragon 810, the 14 nm Snapdragon 820/821 made improvements in processor life, better energy efficiently and has undergone a quantitative change. The Snapdragon 835 has taken these even further.
This is why Xiaomi Mix 2gives outstanding performance even with reduced batter capacity, and it is worth mentioning is Xiaomi Mix 2 power consumption even with playing games are pretty low. The 18W fast charging technology for Xiaomi Mix 2, although not add any brownie points, has an impressive 40 minutes time to charge the battery from 0% to 70%. In summary, Xiaomi Mix 2 is currently the most comprehensive model of Xiaomi at present, with excellent single camera and budget friendly, it is an awesome recommendation to someone who is getting started with Unibody version.
Xiaomi 6 has no full screen or 8GB RAM, Xiaomi Note 3 has Snapdragon 660 instead of latest Snapdragon 835, and Xiaomi Max 2, Xiaomi 5X and Xiaomi 5C are fairly subservient to Xiaomi Mix 2.
Due to these, it seems Xiaomi have elevated Xiaomi Mix 2 as its flagship product of this year. Last year saw Xiaomi 5/5s/5s Plus, Xiaomi Note 2 and Xiaomi Mix presented uneasy situation, but this year with Xiaomi Mix 2, things are looking different.
Now, with Xiaomi Mix 2 is in right track, one can see the clear line of Xiaomi mobile phone in offering for consumers or manufacturers, which seems to be a good thing.
Xiaomi MIX 2 has shouldered the mission of making the idea into reality, a year ago the idea of concept phone started with Xiaomi Mix, but it is Xiaomi Mix 2 which turned it into reality, and now offering large shipments, hence for the customer, the mobile phone industry and for Xiaomi, this Xiaomi Mix 2 is a milestone.
