The perfect Xiaomi 8 transparent exploration version that can't be bought - 上海419贵族宝贝-上海后花园1314-上海品茶网-阿拉爱上海

Xiaomi 8 Transparent Discovery is not a pragmatic mobile phone. This mobile phone was destined to be a futures product at the beginning of its release. Its price is only 699 yuan more expensive than Xiaomi 8 (6+128GB version), but it has bought fingerprint under the pressure sensitive screen, 3D structured light, decorative motherboard+perspective back cover, and 2 GB of memory. If this phone can be launched immediately at the beginning of the launch, and there is no limit to the supply, Lei Jun is really a good person.

However, the fact is that the transparent exploration version of Xiaomi 8 was released on May 30, and it was not until July 30 that it was opened for the first time. Until now (August 8), most of the users who participated in the rush purchase did not use the "phone that made Xiaomi lose money". From the results of our evaluation this time, the two key points of Xiaomi 8 transparent exploration version this time: fingerprint under the pressure sensing screen and 3D structured light are all well done. Its use effect (unlocking speed and unlocking posture) is better than vivo (fingerprint under the screen) and iPhone X (3D structured light). But is it the same as Xiaomi 8 in other aspects?

Parameter configuration

appearance

Regardless of the transparent back cover of the transparent exploration version of Xiaomi 8, the design of this machine in other places is basically the same as that of Xiaomi 8, including the layout of body keys, interface openings, etc.

Through the transparent back cover, users can clearly see the decorative motherboard, batteries, screws and other parts inside the fuselage.

When many users learned that the main board of Xiaomi 8 transparent exploration version was not the real main board, they felt cheated at the first time. But in fact, Xiaomi does it for a reason. First of all, if the real motherboard is placed in such an external position and its ornamental value is taken into consideration, its cooling design will be sacrificed. For a flagship machine, defects in the cooling system will directly affect the user experience; Secondly, this motherboard perspective design, in fact, has no practical value. To put it plainly, it is beautiful and compelling. No one will care whether your naked "Snapdragon 845" is a real SoC in operation. Whether it is a real object or a model, it lies there quietly.

This perspective motherboard uses all copper as the base plate, with steel plate reinforcement, and is configured with 11 sensors, 32 resistors, 6 switch ICs, 7 model control ICs, and 101 capacitors.

Unlike Xiaomi 8, the power button of the transparent exploration version uses a red color scheme.

The metal middle frame of the transparent exploration version adopts a process similar to "bright black", which is very shiny.

Since the transparent Discovery version is equipped with 3D structured light technology, users can see that its bangs are densely covered with various sensors.

The biggest difference between the front design of the transparent exploration version and the Xiaomi 8 is that the row of sensors in the middle of Liu Haizhong is densely packed. The chin and frame at the bottom of the sensor are the same as those of the Xiaomi 8.

Xiaomi 8 transparent exploration version has the same overall use experience as vivo NEX and other models. Its fingerprint identification position is also located at the bottom of the screen. No matter whether the fingerprint identification area is currently displayed on the screen or not, the phone will unlock when the user presses the area when the screen is turned off. This time, Xiaomi uses pressure sensitive fingerprint recognition. Unlike Vivo, users need to press the area when unlocking. If they touch the area lightly, they will not unlock the phone. In addition, when the user presses the button to unlock under the screen, this area will give the user a vibration feedback every time the unlocking is completed.

In fact, the transparent exploration version of Xiaomi 8 has no requirements on the angle of your fingers. Basically, as long as your fingers are free of water and dirt, they can be unlocked successfully. In the case of soft film (non tempered film), the fingerprint unlocking under the screen will not be affected. In terms of speed, compared with vivo NEX, the fingerprint speed of the exploratory version is faster.

3D structured light

Since the iPhone X adopts 3D structured light technology for high-precision face recognition, the industry has set off a wave of 3D Sensing. The so-called "3D Sensing" is actually to achieve high-precision 3D perceptual photography through more sensors. Face recognition is just a small direction of its many applications, and behind it is a larger image recognition market, which can be applied to augmented reality, unmanned driving, intelligent security and other fields.

At present, there are three mainstream schemes in the market that can realize 3D Sensing, namely binocular stereo imaging scheme, ToF scheme and 3D structured light scheme. At present, the mobile phone market is dominated by 3D structured light and ToF, iPhone X、OPPO Find X、 The transparent exploration version of Xiaomi 8 adopts the 3D structured light scheme, while vivo is the ToF scheme camp (corresponding models have not been launched yet).

The transparent exploration version of Xiaomi 8 adopts the 3D structured light scheme of Qualcomm+Himax, which is expected to become the mainstream 3D structured light implementation scheme for Android machines in the future. At present, this scheme has achieved mass production in the first half of 2018.

The transparent exploration version of Xiaomi 8 uses 3D structured light technology, but I believe that many users have noticed the ToF sensor on the official website of Xiaomi as well as the author. In fact, ToF sensor does not mean ToF scheme. In the scheme of 3D structured light, its ToF sensor is only used for auxiliary ranging, which is simply a more advanced distance sensor, different from the complete solution of ToF. Of course, there is also this ToF sensor in the ToF scheme.

The 3D structured light system composition of Xiaomi 8 transparent exploration version is basically the same as that of iPhone X, which uses five sensor modules, namely, infrared camera, ToF ranging sensor+infrared floodlighting element, camera, dot matrix projection, and ambient light sensor.

During the test, we Love to play computer games Found that, Find X、 The three models, Xiaomi 8 transparent exploration version and iPhone X, which use 3D structured light, project different lattice shapes, quantities and ranges. Xiaomi 8 transparent exploration version projects regular maze lattice, while iPhone X has the largest density and range of irregular lattice

Although the dot matrix range of Xiaomi 8 transparent exploration version is smaller than that of iPhone X, its unlocking distance is dozens of centimeters farther than that of iPhone X, and its unlocking posture is more casual. In terms of face unlocking speed, the speed of Xiaomi 8 transparent exploration version is very close to that of Find X, while iPhone X is a little slower.

At present, Alipay and WeChat do not support Xiaomi8 transparent exploratory face recognition payment.

Xiaomi 8 transparent exploration version uses a 6.21-inch AMOLED screen with a resolution of 2248x1080 and a ratio of 18.7:9.

Like Xiaomi 8, it provides users with three screen color modes, namely adaptive, enhanced and standard.

In the standard mode, the color temperature of Xiaomi 8 transparent exploration version is 6600K, the sRGB color gamut is 93.5%, and the sRGB average color standard is 3.2;
In enhancement mode, the color temperature of Xiaomi 8 transparent exploration version is 7100K, the range of DCI-P3 color gamut is 100%, and the average color standard of DCI-P3 color gamut is 2.9;
In the adaptive mode, the color temperature of Xiaomi 8 transparent exploration version is 7100K, the range of DCI-P3 gamut is 82.4%, and the average color standard of DCI-P3 gamut is 3.9;

The maximum brightness of this screen of Xiaomi 8 transparent exploration version is 390~415 nits in manual mode, while the global maximum brightness can reach 550 nits in automatic brightness mode with strong light.

The Xiaomi8 and Xiaomi8 transparent exploration version on our hands use Samsung's AMOLED screens, and both models are ea8074. From the test results, although the two mobile phones are basically the same in terms of the maximum brightness and brightness uniformity of the screen, this Xiaomi 8 transparent exploration version has better screen tuning and color accuracy performance than the previous Xiaomi 8.

Performance

In terms of running score, the running score of the transparent exploration version of Xiaomi 8 is basically the same as that of Xiaomi 8, which falls within the normal range of 845 points of Snapdragon. However, it is worth noting that the random write of the flash memory of the transparent exploration version of Xiaomi 8 is much lower than that of Xiaomi 8, but after comparing the file systems of the two mobile phones, it is found that there is no difference between them.

In terms of GPU pressure test, the performance of Xiaomi 8's GPU is more stable and durable.

In the CPU pressure test of Gunshen, the high frequency state of Xiaomi 8 is more lasting than that of the exploration version, and the curve is more stable. The overall performance is better than that of the exploration version.

In the actual test, the size and size of the transparent exploration version of Xiaomi 8 are more actively regulated than the ordinary version of Xiaomi 8, and the frequency of the CPU cores of the exploration version is generally higher than that of Xiaomi 8.

In terms of the hardware parameters of the rear dual camera, the transparent exploration version of Xiaomi 8 is completely the same as that of Xiaomi 8. Both are four axis optical anti shake, IMX363 of F1.8 and S5K3M3 of F2.4, and the focal length is also the same. In theory, the photographic experience of the two should be very similar. At the same time, we add Xiaomi MIX 2S here. Its camera parameters are also four axis optical anti shake, IMX363 of F1.8 and S5K3M3 of F2.4, which are consistent with Xiaomi 8 series.

In terms of daytime performance, there is no obvious gap between the three. Although the hardware parameters of the three mobile phones are consistent, the performance of the MIX 2S is rarely different from the other two, but the gap is very small in general.

In particular, the performance of Xiaomi 8 and Explorer is very similar, and the effect of white balance is almost the same. In terms of analytical force, their smearing algorithm and sharpening degree are almost the same. Although they are not able to take identical photos, they are both within the error range, which can be considered as the same level. Among the three machines, the algorithm of MIX 2S is obviously different, especially in the performance of analytical force. Its choice between sharpening and smearing is obviously different from the other two.

In terms of secondary photography, the Discovery version has some abnormal performance, and its sharpness is higher than the other two, but its overall picture, especially the solid background picture, has a lot of noise, which may be related to our MIUI 10.8.8.3 development version system of the Discovery version.

at night

In the aspect of night scene, in the scene with complex lights, the white balance of MIX 2S will show some deviation, while the performance of Xiaomi 8 and the exploration version is very close, and more close to the white balance of the real scene. In terms of glare, there is no problem with the three machines. In the case of complex point light sources and ambient light, there is no obvious omni light or glare on the three machines. The three mobile phones are basically equal in terms of night scene resolution, especially the performance of Mi8 and Discovery.

In general, the photography gap between the three is small, especially for Xiaomi 8 and Explorer. The sample effect of the two is within the allowable error range, which can be considered as the same level. The MIX 2S is one of the three sets with relatively large differences. The white balance is slightly poor, and daytime analysis pays more attention to smearing.

Fast charging&endurance

The Xiaomi 8 transparent exploration version is the same as the Xiaomi 8. The machine itself supports QC4+fast charging, but the official accessories only provide a QC3.0 fast charging head. The measured charging power of Xiaomi 8 transparent exploration version is about 15W under the condition of low power (5%~30%).

Although the charging power is not high, the charging speed of Xiaomi 8 transparent exploration version is very fast. It takes about 75 minutes to charge from 5% to 100%, which is nearly 30 minutes faster than Xiaomi 8. For this test result, first of all, the battery capacity of the transparent exploration version of Xiaomi 8 is 400mAh less than that of Xiaomi 8. In addition, the trickle charging time is also very short (the last 10% trickle charging of the ordinary version takes half an hour to be fully charged), resulting in a shorter final charging time.

Since the hardware parameter configuration is basically the same as that of Xiaomi 8, and the battery capacity of the transparent exploration version of Xiaomi 8 is 400mAh less, Xiaomi 8 is better than Xiaomi 8 in terms of endurance. In our 2-hour endurance test, Xiaomi 8 opened a 3% gap with the Discovery version, and the endurance level of the Discovery version was close to that of the Xiaomi 8 SE.

summary

Just like our initial impression of Xiaomi 8, the transparent exploration version of Xiaomi 8 is a Xiaomi 8 with under screen fingerprint+3D structured light, and its experience of these two "unlocking black technologies" is also very good. We have to admit that, as the future technology trend of the market, offline fingerprint and 3D structured light have no substantive function changes or additional use scenarios for users, but as the flagship standard configuration technology recognized by the market, they will certainly be the mainstream of future flagship computers.

As the flagship work of Xiaomi this year, the Xiaomi 8 series should indeed be equipped with offline fingerprint/3D structured light, but Xiaomi's products always pay attention to cost performance and are very strict in cost control. Therefore, Xiaomi has launched the pragmatic version of Xiaomi 8 and the cool version of Discovery, giving users the choice.

The official price of the transparent exploration version of Xiaomi 8 is only 700 higher than that of Xiaomi 8, which also maintains the traditional cost performance style of Xiaomi, but it is still a futures product. From the market quotation, this product is extremely out of stock, and the market recovery price is nearly 500 yuan higher than the official price. It can be predicted that in the future, it will be difficult for users to buy the transparent exploration version of Xiaomi 8 at the original price, which is the problem.
