Have seen a very interesting point: traditional enterprises, as long as you live unremitting efforts to survive, there is always a summit day; Internet companies are different, you can only wait for the so-called "flood." Whenever a tuyere arrives, there will always be people flying high, especially for the mobile phone industry. A few years ago, the transition from 3G to 4G brought about the "Internet phone" outlet, creating the emergence and brilliance of a large number of smart phone brands in the next few years. Under the big winds, with the small tune brought by technology upgrades, it is the evolution of smart phones once and for all that makes people "perfect." This time, it is a "full screen."
One, millet MIX2 configuration analysis
In terms of configuration, Xiaomi MIX2 did not disappoint this time. It is Xiaomi's first 8GB memory phone and is one of the few 8GB memory phones in the world.
If you have to grab a first, it is the world's first 8GB memory full screen mobile phone, or the first 8GB memory ceramic mobile phone.
Millet MIX2 configuration parameters introduced screen specifications 5.99 inches 18:9 full screen CPU model Qualcomm Snapdragon 835 (64-bit eight-core) RAM Memory Standard Edition / High Edition / Enjoy Edition: 6GB Full Ceramic Enjoyed Edition: 8GB ROM Storage Standard Edition : 64GB High Edition: 128GB Exclusive Version: 256GB Full Ceramic Premium Version: 128GB Camera Specifications 5M Front and Rear 12M Pixel (Sony IMX386, supports 4-axis optical image stabilization and PDAF phase focus) Battery capacity 3400mAh (support 9V/2A fast charging) Network standard full Netcom 4.0 6 mode 43 frequency (dual card dual standby) operating system MIUI 9 (based on Android 7.1) body size 151.8x75.5x7.7mm (185g) body color standard version / high version / Privilege Edition Black All-ceramic Privilege Edition with black and white moon reference price 3299 yuan / 3599 yuan / 3999 yuan full ceramic exclusive version 4699 yuan mobile phone features full screen, fingerprint identification, full-featured NFC, four-surface ceramic mobile phone evaluation Zealer Video: Wang Xiaomi MIX2 self-test videoFirst of all, in terms of size, Xiaomi MIX2 is divided into two versions of the standard version and the exclusive version, in which the standard version is a metal frame + ceramic body, exclusive version uses a more complex Unibody ceramic technology, size compared to the standard version Slightly smaller, but more weight 2g, the impact of such a difference in the sense of the opponent should be minimal.
Compared to the millet MIX, because the screen size is reduced by 0.4 inches, so the Xiaomi MIX2's body is a small circle, while the body is also thinner, the weight is also lighter than 20 g, one-handed holding no pressure. At the same time, thanks to the more rounded frame, the rear shell uses a four-curved design and feels better.
Configuration, the millet MIX2 uses a 5.99-inch 18:9 display, equipped with Snapdragon 835 processor, built-in 6/8GB RAM and 64/128/256GB body storage space, providing a front 500 million pixel camera and rear 12 million pixels Camera (Millet 6 main camera with the same IMX386), supports dual card dual standby full Netcom 4.0 and 18W fast charge.
It is worth mentioning that this millet is equipped with a 6-mode, 43-band full Netcom to millet MIX2. This is probably the mobile phone that supports the largest number of bands at present. It is good news for users who often go overseas. Xiaomi claims that it can support any one. Carrier's 4G network.
This means that the millet MIX2 will target high-end business users, this part of the user is not bad money, but also has outstanding appeal. If Xiaomi can open gaps in this group of users through Xiaomi MIX2, the future is bound to have a lot to do in the high-end market.
In addition, it should be noted that the millet MIX2 Standard Edition has 6+64, 6+128, and 6+256 types of capacity, while the exclusive version only offers 8+128GB versions.
Second, millet MIX2 appearance evaluation
Millet MIX as a millet's first full-screen concept mobile phone is a typical design-driven product. The aggressive design on the outside brings some compromises in user experience, such as the handset, grip, and front camera. And millet MIX2 is a full-screen mobile phone that is truly for the average user, and has made some beneficial improvements in some aspects related to the user's actual experience.
earpiece
Because of the cancellation of the forehead, the top of the millet MIX fuselage can not accommodate the traditional shape of the diaphragm sound receiver, so the piezoelectric ceramic vibration solution is adopted, the electrical signal is converted into mechanical vibration, the body border sound, but the actual experience Not good, widely criticized.
In response to this problem, Xiaomi MIX2 has returned to the traditional diaphragm sound program. The mobile phone with the membrane-based handset program will retain a relatively large "forehead" at the top of the screen to make room for the handset, but Xiaomi MIX2 obviously will not do so. It innovatively places the handset at the bottom of the screen and transmits the sound through the sound tube to the sound hole at the top of the screen to complete the sound transmission of the call.
From the above figure, we can see that this sound hole is extremely small, and it does not affect the frontal view of the whole machine. I think this is a most commendable and ingenious one for the Xiaomi MIX2.
Holding touch
For Xiaomi MIX, appearance is also a point of complaint. Because the use of a large 6.44-inch screen, body size is not small, plus straight up and down the rigid line design, millet MIX grip is not comfortable. Of course, there are also users who like this halo-style look, but it looks nice and not practical. For the grip feel, Xiaomi MIX2 improved from the following aspects.
(1) Screen size: 6.44 to 5.99 inches.
Although, millet MIX fuselage borders are very narrow, reaching a screen share of 91.3. But on the 6.44-inch screen, the size of the machine is not friendly to most people. Millet MIX2 uses a 5.99-inch screen with a resolution of 2160*1080. Standard version of the millet MIX2 body length and width control in the 151.8 * 75.5mm, than the iPhone7Plus (158.2 * 77.9mm) with a 5.5-inch screen even smaller. Further narrowing the body size makes the MIX2 MIX2 more suitable for most people holding in one hand.
And more rare is that millet MIX2 exclusive version uses Unibody four-surface full ceramic body. The body size is further narrowed, with a length and width of 150.5*74.6 mm, respectively. In addition to higher integrity, ceramic materials have superior specular gloss to glass. The key is higher hardness, Mohs hardness of 8.5, second only to sapphires and diamonds, more scratch resistant.
However, because of the hard and brittle nature of the ceramic material, it is difficult to process and costly. From the February 2016 edition of the 5th edition of the millet, the ceramic material has become the identity label of Xiaomi’s flagship mobile phone. With millet's continuous exploration of the ceramic body technology, the ceramic material has really entered the mass consumer market.
(2) Screen ratio: 17:9 to 18:9
The millet MIX2 uses an 18:9 aspect ratio screen with a higher aspect ratio, which means that with the same display area, the millet MIX2 has a narrower body and improves one-handed comfort.
The 18:9 aspect of the screen is far more than that. Some users may have noticed that the two American dramas, "House of Cards" and "Strange Stories" produced by Netlyix, a well-known streaming media site, have taken the lead in adopting an 18:9 ratio. Samsung’s flagship phones, the S8 and Note8, all use 18:9 screen ratios this year. According to the latest flagship mobile phones, the entire industry may transition to the 18:9 screen in the future. The reason is that it can balance the ratio of modern television content 16:9 and widescreen standard 2.35:1/2.39:1. The future of mobile will be the explosion of content in the "image integration" format, which means that after the format is popular, there will be no annoying black borders when watching videos.
Therefore, Xiaomi MIX2 is still a very forward-looking work.
(3) Four curved ceramic design, the machine is more rounded corners.
In appearance design, Xiaomi MIX2 completely broke the tough style of Xiaomi MIX straight up and down. It uses a four-curved ceramic body design that fits perfectly with the palm of your hand when held normally. In addition, the frame of the body of the millet MIX is also designed in a radian shape so that it does not have a noticeable grip.
Of course, some people like the tough style, and some people like the mellow style. This change in the appearance style of the millet MIX2 is to take care of the actual needs of most users for holding the hand. A product cannot be made to be enjoyed by all, but if more people can enjoy it, it will be a great improvement.
It can be seen that in terms of grip and handset, Xiaomi MIX2 has made some effective improvements without affecting the overall screen share. It has abandoned some of the "conceptual" designs that are not practical and has evolved to version 2.0. The millet MIX2 has a mass property and is a full-screen mobile phone that can really be used for all-round use.
Third, millet MIX2 system experience
Before the beginning of this section, it should be noted that the tester I got was running the MIUI9 development system. The future retail version is pre-installed MIUI8 stable version, but after the conference, MIUI will provide MIUI9 development version on the official website to download, users can unlock their own brush.
In addition, after the release of the stable version of MIUI9 in the future, I believe that Xiaomi will also carry the MIUI9 stable system directly in the future sales version.
As millet's highest positioning and most powerful model, all the functions of MIUI9 will not be missed in the millet MIX2. Due to time constraints, we will not be introduced one by one. Interested ones can refer to our previous MIUI9 detailed experience.
Personal Assistant 2.0, including monthly payouts, memos, sports pedometers, stock information, favorites, and courier information, can all be displayed on a negative screen.
Fourth, millet MIX2 performance test
Hardware performance: Snapdragon 835+8GB memory and what do you mean?
Millet MIX2 equipped with Snapdragon 835 processor, built-in 6/8GB memory and 64/128/256GB body storage space, and the entire system comes standard with UFS2.1 flash memory, this is probably the most current flagship mobile phone should do.
Ann Bunny's total score is easily over 180,000, which is still 6GB version, 8GB Premium Edition theoretically will have a better performance.
UFS flash memory test, continuous reading up to 740MB/s or more, continuous writing up to 240MB/s or more, 4KB random read/write speeds of 130MB/s and 21MB/s, respectively, the overall performance is lower than the author's hand 6 ceramic exclusive version slightly better.
In my opinion, any flagship mobile phone equipped with the Snapdragon 835 will almost certainly not have any problems with performance, whether it is the fluency of daily use or the performance of large-scale 3D games.
Five, millet MIX2 photo test
From the point of view of product positioning, millet MIX is a product that raises Xiaomi's brand, and industrial design ranks first. Therefore, inviting Philippe Starck as a designer, a series of breakthrough conventional designs such as a full-screen, full-featured ceramic body were adopted. It is precisely because this is a design-driven product that leads it to perform less well in some aspects than its competitors.
Perhaps in order to ensure that the rear camera of the Xiaomi MIX did not protrude, Xiaomi did not use the industry-leading CMOS on the phone, which also made its camera performance unsatisfactory. However, with the improvement of the overall screen production capacity and the upgrade of the ceramics process, the millet MIX2 will not only be a concept mobile phone, but it will need to carry the mass production mission. To this end, millet MIX2 must at least reach the flagship level in the camera to be satisfactory.
The millet MIX2 uses the same CMOS as the Xiaomi 6 main camera, the Sony IMX386. The sensor supports up to 12 million pixels, has F2.0 aperture, a single pixel area of ​​1.25μm, supports PDAF phase focus, four-axis optical image stabilization. In terms of functionality, Xiaomi MIX2 supports axis-shifting cameras, night scene enhancements, beauty modes, and more.
The recent weather in Beijing is not very good. It's a shame that you can't take photos of the blue skies to please the eye. It's a pity that we'll take a look at Xiaomi MIX2's proofs.
The three outdoor photos from the above highlight the adjustment style of the millet MIX2 camera. When the colors of red, green and blue appear in the environment, the millet MIX2 will adjust it more vividly. Such as the sky in Figure 1, the green trees in Figure 2, and the trains and green spaces in Figure 3, this method of adjustment is obviously more user-friendly.
In addition, the tolerance of the millet MIX2 camera is relatively general, and it is recommended to open the HDR mode and take pictures in most cases. This often results in better pictures.
It is worth mentioning that the millet MIX2's continuous shooting function is very good, long press the shutter can basically reach the shooting speed of 10 per second. This function is usually used to photograph your girlfriend when it is most practical, because you can make your girlfriend do any coherent action she wants to do. You can save multiple photos of the entire action through continuous shooting, and then filter. One of the best. Through the continuous shooting function, the expression of his girlfriend when posing is not natural.
In addition, night scene enhancements in the Xiaomi MIX2 camera are also very own. After it was turned on, the camera speed was not delayed due to multiple compositing, and the camera still maintained almost the same speed as the normal mode. However, photos taken in this way will greatly increase the fineness of the picture and reduce noise. However, the night view enhancement function cannot be turned on at the same time as HDR. Therefore, it is recommended that you use the HDR mode when there is plenty of light during the day, and turn on the night view enhancement by default when there is insufficient light in the night.
In general, compared with the previous generation, the millet MIX2 has greatly improved the level of photographing, but with it comes the camera will also be slightly protruding. For now, the Sony IMX386 adopted by the Xiaomi MIX2 has been tuned to a very mature level by Xiaomi. Both the camera experience and the imaging effect can be satisfactory, but the lack of dual camera makes the Xiaomi MIX2 no portrait mode. Somewhat sorry. In addition, Xiaomi also began to pay attention to this part of the photo editing, MIUI9 built a variety of filters and a wealth of adjustment features, it will be more convenient to use.
VI. Millet MIX2 battery life and charging test
Charging and battery life: No problem in one day
Milli 6's battery life is a surprise. It has no problem with the 3350mAh battery.
Millet MIX2's battery capacity of 3400mAh, with the Snapdragon 835 mobile platform, it theoretically has no loss in millet 6's battery life. Unfortunately, due to limited evaluation time, detailed battery life tests will be added later.
Charging part of the author to simply experience, using the original 18W fast charge head and data line, in 20 minutes to increase the power from 44% to 79%, the system prompts about 15 minutes to fill.
According to this speed to speculate, millet MIX2 from 0 to fully charged time will probably be about 1 and a half hours (millet last trickle charging speed is slower), an hour or so should be able to rush into more than 80% of electricity, although the performance Not amazing, but it's enough.
In addition, from the late MIUI8, Xiaomi has quietly joined the fast charge icon. If the mobile phone is in a fast-charged state, there will be corresponding prompts on the screen, and at the same time, an estimated charging time will be given. This aspect is very user-friendly.
Millet MIX has been criticized for call problems. Has it improved?
The comprehensive screen design adopted by Xiaomi MIX has broken through the traditional hardware design of mobile phones, which has caused Xiaomi to recreate a new solution for this, and the cantilever piezoelectric ceramic sound guide is one of them. We will understand this by splitting the technology into two words, "cantilever" and "piezoelectric ceramic."
Piezoelectric ceramics: Piezoelectric ceramics are a type of piezoelectric material that is a material that converts electrical and mechanical energy. The biggest feature is its piezoelectric properties. When a voltage is applied to the piezoelectric ceramic, the ceramic will deform to generate vibrations. The vibration will drive the movement of the surrounding air, and different frequencies will produce different amplitudes to produce different sounds.
Cantilever: From the internal dismantling picture of the millet MIX, you can see that the millet MIX will place the piezoelectric ceramics in a hollow position by a screw in the mobile phone. When the phone is connected, the drive unit converts the electrical signal directly into mechanical energy, and drives the mid-box resonance through the click of the micro-vibration. Different frequencies bring different amplitudes, and different amplitudes translate into different daily sounds. Finally through the upper frame of the fuselage to the human ear.
Although this technology seems to be “tallâ€, it seems to be somewhat unsatisfying when it comes to daily use. Due to the use of a cantilevered piezo-ceramic sound conduction scheme, Xiaomi MIX actually does not have a handset. During the call, the sound is the piezoelectric ceramic inside the fuselage transduced to the cantilever by vibration, the cantilever is connected with the middle frame, and the human ear is attached to the middle frame of the mobile phone to hear the sound.
This millet MIX2 returned to the traditional capsule headset design, and to meet the full screen hardware design requirements. Millet MIX2 uses a screen design, the handset unit is placed on the back of the screen, through a sound tube to the sound to the top of the screen a very small sound hole to complete the call sound conduction. Through the author's test, Xiaomi MIX2 really solved the call problem on Xiaomi MIX. However, the tiny cracks in the receiver make it difficult to clean the dust after it is accumulated. Covering the handset with dust after prolonged use leads to a reduction in call quality.
How to achieve high screen ratio? These two technologies are perfect
In the above, we have already mentioned that the Xiaomi MIX2 enjoyment version uses a brand new Unibody ceramic. This is not traditionally the Jingdezhen's geotechnical ceramics. It is a reinforced ceramics process. Its composition is a nano-zirconia powder. The particle size is only 50nm.
Through powder preparation, mold forming, high-temperature sintering and post-processing processes, the rear shell of millet MIX2 can finally be created. The process lasts for about 10 days.
Compared to glass, ceramics have inherent advantages in hardness and feel, Mohs hardness up to 8.5, second only to sapphire and diamond and other materials, and electromagnetic shielding is minimal. This also provides the foundation for the Mimi MIX2 to implement a 6-mode, 43-band global communicator, which can support any operator's 4G network in the world.
Guided receiver
The millet MIX2 returned to the traditional design of a film-type handset, but Xiaomi effectively avoided the appearance of a big forehead by placing the handset unit on the back of the screen. The sound was transmitted through a sound tube to the top of the screen. The sound hole completes the voice transmission and guarantees a full screen design.
The author specifically compared the conversation with Xiaomi 6, and the two did not have any difference in experience. It was an earth-shaking change compared to the Xiaomi MIX (Millet MIX used a ceramic box to conduct sound and the sound quality was poor).
Ultrasonic distance sensor
The ultrasonic distance sensor on the MIX MIX was retained on the Xiaomi MIX2, abandoning the traditional infrared sensor, which is the basis for achieving a high screen share.
Specifically, the Xiaomi MIX2 is equipped with an ultrasonic transmitter inside the fuselage and emits a 40-kHz drive signal. It spreads out through the gap between the screen and the top border of the phone. The signal senses the position and status of the external obstacles and reflects back to complete a specific detection. .
In simple terms, it is similar to the technology of reversing radar, but it will be more advanced on mobile phones.
It is the combination of a sound-guided earpiece and an ultrasonic distance sensor that makes the Xiaomi MIX2 have no forehead, laying the foundation for the high-screen share. But it is worth mentioning that because of the sound hole added to the top of the screen, the screen top border of the millet MIX2 is slightly wider than the Xiaomi MIX.
Evaluation summary:
Although the millet MIX last year was amazing to the author, but the actual use of the experience is not very good, the author insisted on using it for two weeks or so can only be used as a backup machine. This millet MIX2 can be said to be a change in the "illness" of Xiaomi MIX. After a simple experience, the author has plans to use it as a main machine.
In terms of appearance, it continues the design of Xiaomi MIX. The reduction of the screen size makes the whole size close to perfect. The curved frame and the thinner body also bring a better feeling. There is no pressure in one-handed operation. Although the weight of more than 180g is still not light, but for the writer who is accustomed to the weight of millet 6 is not a problem.
In terms of the most important voice quality, Xiaomi MIX2 has returned to the traditional handset design. Although this makes the top border look a bit wider than Xiaomi MIX, this sacrifice is worthwhile. The call experience is no different from ordinary mobile phones. .
Configuration does not need to mention, Xiaolong 835 plus 6GB of memory and the entire system comes standard with UFS2.1 flash memory, there are not many mobile phones can have such a configuration, absolutely worthy of the title of the flagship.
In addition, the addition of the four-axis anti-shake IMX386 has improved the photographs of the millet MIX2. Although the performance is not as good as that of the Xiaomi 6, they are generally sufficient for use and have no obvious shortcomings.
Millet MIX was dubbed the concept machine because it couldn't achieve mass production. The millet MIX2 should throw away this hat.
In theory, with the upgrading of the supply chain, Xiaomi MIX2 currently has no barriers to large-scale mass production. It is believed that the initial production capacity will have a particularly noticeable improvement when compared to the launch of Xiaomi MIX.
There is no doubt that the Xiaomi MIX2 is a well-deserved Android flagship. When the top hardware is coupled with the easy-to-use MIUI9, the actual experience on Xiaomi 6 makes it unnecessary to say much about the practical experience of Xiaomi MIX2. And interestingly, last year, Xiaomi also positioned MIX as a full-screen concept mobile phone. This year, MIX will gradually “conceptualize†it. By using more traditional handsets and filling in flaws that were criticized last year, MIX2 will be built into a The regular flagship product. When the concept shines into reality, this is Xiaomi MIX2 that Xiaomi brought us.
