In recent years, the popularity of domestic smart phones is rapid, the market is gradually saturated, and user consumption is upgrading. For most users, high matching and low price is not the most important factor to promote users' purchase. Consumers' attention has shifted more to the technology, performance and materials of mobile phones. The red rice Pro released this time is a new series of red rice mobile phones, which is positioned on the red rice Note. Lei Jun also sent Weibo to say that "Red Rice Pro is the flagship of Redmi", so what are the real skills of this mobile phone and whether it can live up to the word "flagship"? Let's analyze them one by one through evaluation.
First, let's take a look at the main selling points of Red Rice Pro: CNC metal integrated body, dual cameras, and MediaTek's top Helio X25 ten-core processor (the same as Meizu Pro 6). It doesn't seem strange to install MediaTek's flagship processor of the year on Red Rice mobile phone, but it is the first time to use CNC metal integrated body and dual cameras on Red Rice mobile phone. In addition, the Red Rice Pro is equipped with a fingerprint identification button, which is front-pressed and uses a 5.5-inch OLED screen. From these points alone, Red Rice Pro does have the confidence to call itself the "flagship".
The following are the main hardware parameters of Red Rice Pro.

Red rice Pro has three versions: standard version, high-end version and top version. Except that the running memory is different from the body storage, the standard version uses MediaTek Helio X20 processor. The difference between Helio X25 and Helio X20 is that the CPU frequency is increased from 2.3GHz to 2.5GHz, and the GPU frequency is increased from 780MHz to 850MHz. It can be considered that X25 is an overclocked version of X20, with better performance. MediaTek X20/X25 processor supports depth of field and dual camera technology for the first time, which provides hardware support for Red Rice Pro equipped with dual cameras.
Last year, MediaTek released the high-end Helio X 10 processor, but the red rice Note3 released shortly afterwards was equipped with this processor, which made MediaTek's flagship strategy go up in smoke. When MediaTek, who made a comeback this year, released its flagship chip X20/X25, it also said that Meizu enjoyed the exclusive period of Helio X25 for several months, and its flagship Pro 6 was equipped with this processor. Meizu Pro 6 still maintains the price of 2499 yuan. If we don't discuss the design, process and technology, the high-grade red rice Pro with a price of 1499 yuan but similar overall hardware performance is enough to make it feel ashamed. This higher positioning red rice mobile phone still has a cost-effective gene.

"1, Brief Analysis of Appearance Design
On the front of the fuselage, the design of Red Rice Pro is simple, and there is no logo on the front of the fuselage (which also keeps the tradition of Redmi series mobile phones) and no other decorative elements. The front screen also adopts the currently popular 2.5D glass design. The control of the black edge of the screen is quite satisfactory, which belongs to the general level. It is worth noting that Red Rice Pro uses a 5.5-inch organic light-emitting diode FHD screen, which is the first time in Xiaomi mobile phone products. Compared with traditional liquid crystal, organic light-emitting diode screen has many advantages, such as low energy consumption, wide color gamut, bright colors and better impression.
About a year ago, a thousand yuan machine could blow a lot if it used a metal body, but now the metal body has been rapidly popularized, and even some hundred yuan machines have used metal materials. As the flagship product of Redmi series, Red Rice Pro has made a new attempt in technology compared with previous Red Rice Note3 and Redmi 3, adopting CNC integrated body design.
This technology is mostly used in flagship models (which will be introduced in detail later), and it is rare in models with the same price as Red Rice Pro. Similarly, injection molding strips are added at the upper and lower ends to solve the signal shielding problem of metal. The shape of the back of the fuselage is a bit similar to Xiaomi Note, which is designed for the radians on both sides and takes care of the grip. It is worth mentioning that Red Rice Pro also uses a brushed surface treatment on the fuselage, which visually brings a strong metallic feeling.
Symmetric design is a popular design on mobile phones recently. Order produces beauty, and the symmetry element on the fuselage looks more concise and visually more balanced. The data interface is USB Type-C, which has been rapidly popularized in 20 16. Compared with ordinary Micro USB, it has obvious advantages and can provide higher charging current and faster data transmission speed. It is the quasi-successor of Micro USB.
At the bottom of the front of the fuselage, Red Rice Pro is equipped with a pre-pressing fingerprint identification key, which is the first time that Redmi series mobile phones adopt a pre-pressing fingerprint key design. Whether the fingerprint button is good on the front or the back has been debated. Which way is more convenient varies from person to person, so we won't discuss it. However, it is undeniable that the bottom of the mobile phone is usually integrated with 2/3/4G RF antenna, and the space at the bottom is very limited, which is more difficult to achieve than fingerprint identification on the back. The fingerprint of Red Rice Pro finally supported Alipay's fingerprint payment, which brought great convenience to payment. It is reported that red rice mobile phones with fingerprint recognition function such as Xiaomi and Xiaomi 5 will also support Alipay fingerprint payment in the third quarter.
On the back of the fuselage, Red Rice Pro adopts dual camera design for the first time, which is also a big selling point of this phone. The above is Sony's13 megapixel IMX258 camera sensor, which is responsible for recording pictures; Below is a 5 megapixel camera sensor from Samsung to assist in depth of field recording. Because Helio X25 processor supports hybrid autofocus and real-time background blur, it extends the playability of camera imaging of Red Rice Pro.
The Red Rice Pro designed with CNC metal integrated body is a breakthrough in appearance for Redmi series. The surface treatment of metal wire drawing makes it full of metal feeling and has high recognition.

"2, talk about mobile phone metal body technology.
At present, three processes are widely used in mobile phones with metal body in the industry: die casting, stamping and CNC.
The production process of die casting is that the liquid metal of molten clothing is filled into the mold through pressure and cooled to form. The main problem faced by this technology in the application of mobile phone fuselage is that there will be more or less air holes in the die casting process, and the surface is difficult to handle, so a thick layer of paint is generally needed. The representative model of die casting is charm blue metal. At that time, Charm Blue metal mainly focused on the metal body. However, due to the die casting process, the back of the fuselage had to be treated with thick paint, which felt plastic.
Stamping is to press the metal plate out of the metal plate with a punch, but the metal plate that can be used for stamping is relatively thin, which is not convenient for reprocessing, so the final result is often a deformed metal plate. Generally, the upper and lower ends are spliced with plastic materials, and then surface treatment is carried out to keep the colors of the two materials consistent. However, due to the natural properties of different materials, the two colors can never be completely consistent, and there is natural color difference, which destroys the integrity of the fuselage. The representative model is Red Rice Note3.
The above two technologies are simple and the manufacturing cost is relatively cheap, so they are mostly used in low-end mobile phones. The remaining one is CNC (Numerical Control Machine Tool) machining. It cuts, drills and polishes a whole piece of metal through a numerical control machine tool to obtain a complete metal shell. NC machining has many processes, high precision and low cost, so most mobile phone manufacturers generally only use this technology on flagship models. In order to solve the signal shielding problem of metal, it is necessary to open a window on the fuselage or carry out nano-injection molding, but the integration degree is the highest among the three processes.
This red rice Pro body is designed with an integrated metal body processed by CNC, and the surface is brushed with metal. CNC and metal wire drawing, Red Rice Pro really put more thought into the fuselage technology than the previous Redmi models, especially the metal wire drawing on the back. At first glance, it's all metal. In terms of perception, Red Rice Pro has a strong metallic feeling, but it is not the case in touch. The back of HTC One M9 fuselage is also brushed with metal. Compared with HTC One M9, Red Rice Pro adds a polishing treatment on the basis of wire drawing, which increases the surface gloss. However, this treatment weakens the level of drawing texture and has a glass-like touch.

3. What are the improvements of MediaTek Helio X25 compared with Helio X 10?
The red rice Pro we got is a high-end version, equipped with MediaTek Helio X25 processor. In the first half of this year, several models have been equipped with MediaTek Helio X20(360 mobile phone N4, Meizu MX6) and Helio X25 processor (Meizu Pro 6, Le 2 Pro). As mentioned above, the difference between these two processors is that the main frequency of CPU and GPU is different (the main frequency of CPU is increased from 2.3GHz to 2.5GHz and the main frequency of GPU is increased from 780MHz to 850MHz). Red Rice Note3 is equipped with MediaTek's flagship processor Helio X 10, and the positioning of Red Rice Pro is higher than that of Red Rice Note series. So in terms of processors, as MediaTek's flagship chip this year, what improvements does Helio X25 have compared with Helio X20?
The improvement of Helio X25 compared with Helio X20 is mainly reflected in five aspects:
1, 10 core, 3 cluster architecture. Helio X20 adopts 20nm technology and has two A72, four high-frequency A53 and four low-frequency A53 cores *** 10. In MediaTek's official introduction, we saw that engineers divided the operating mode of this processor into three grades: high performance, balance and low power consumption, which is what the government called "three-cluster architecture". The advantage of this is that it can adapt to more application scenarios and optimize the performance of power consumption during use. A relatively appropriate metaphor, this is somewhat similar to the gear of a car. Different gears are used to deal with different road sections and improve efficiency.
2.GPU performance and power consumption performance upgrade. MediaTek's previous generation flagship processor Helio X 10 uses Power VR G6200, and its performance is not the same as that of Snapdragon 8 10 in the same period, even worse than that of Qualcomm 80 1 Adreno 330. This time, Helio X20 uses ARM's Mali-T880. According to official data, compared with Mali-T760 unit, the performance is 180%, and the energy efficiency is improved by 40%. At the same time, it supports the latest OpenGL ES 3.1/DirectX11.2 standard.
3. Multimedia function upgrade. Helio X20 supports a main camera with a maximum of 32 megapixels, a built-in 3D depth engine, and a new generation of noise reduction and demosaicing hardware functions. I believe that the ability to shoot at night will be further improved. In addition, it also supports13 megapixel dual cameras, and the hardware supports 4Kx2K video playback with 30 frames per second. The improvement of these functions makes it one of the main reference chips of dual-camera mobile phones in the future.
4. Built-in ARM Cortex-M4 processor. Mainly used to deal with some applications that don't need too much computation, such as background MP3 playback or Samsung's always-on function. The sensor hub has an independent energy management system, which can work in a low-power environment.
5. Global full-mode modem. In 20 13, MediaTek acquired the CDMA patent license of Wei Rui Dentsu, but it was not until last year that it began to actively lay out the whole netcom chip. Helio X20, which is positioned at the high end, has the property of full netcom, and will naturally become the standard of MediaTek's flagship chip in the future. In addition, Helio X20 supports high-definition voice calls between Cat.6 carrier aggregation and VoLTE.

"4, red rice Pro performance running test
Let's take a look at Ann Bunny's running score first.
Red rice Pro equipped with MediaTek Helio X25 and 4GB running memory achieved 8352 1 in Antu's running test, and the single performance score of CPU was 235 16. (Environmental factors have a great influence on the test results. This data is for reference only and is not typical). Most models of Helio X25 can reach more than 90,000 in most cases, which is roughly equivalent to Huawei P9 (equipped with Kirin 955 processor) and Samsung Galaxy Note5 (equipped with Samsung Exynos 7420 processor). At present, the test scores of Ann Bunny equipped with Xiaolong 820 processor are mostly above 12000. There is a gap in computing performance between Helio X25 and Xiaolong 820, but the gap is not very big.
▲ Red Rice Pro 1080P Tyrannosaurus Rex Screen Test
▲ Red Rice Pro 1080P Manhattan Screen Test
GPU performance test with GFXBench shows that Red Rice Pro achieved 1393.7 and 8 19. 15 in the off-screen test of Tyrannosaurus Rex and the off-screen appearance test of Manhattan respectively. This kind of achievement can only be said to be quite satisfactory. GPU is still the weak link of MediaTek chip, and the performance of GPU mainly determines the fluency of playing games. Helio X25 is no problem for most mainstream applications, but it is not enough for a large single-player mobile game like NBA 2K 16. Compared with Adreno 530( 1080P Manhattan off-screen test score 1 182.5) used by Qualcomm Xiaolong 820, Mali T880MP4 chip used by Helio X25 is still not in the same grade. However, after this upgrade, its performance has been at the same level as Samsung's previous generation Exynos 7420 (representative model Samsung Galaxy S6), which is almost double that of its previous generation chip.
Compared with this year's flagship chip Xiaolong 820, MediaTek Helio X25 processor is in the first echelon in CPU performance, and overall power consumption control is a big advantage of MediaTek. However, compared with the flagship chips of Samsung and Qualcomm, the performance of GPU is obviously inferior. It is also a pity that DDR4 memory is not supported. In terms of comprehensive performance, MediaTek Helio X25 is still difficult to carry the high-end banner.
"5. Dual-camera imaging analysis+real sample.
As the flagship model of Redmi series, Red Rice Pro not only lags behind the existing Redmi products in configuration, but also seeks some differentiated breakthroughs in some functional points. Red rice Pro adopts the design of dual cameras, which is also the first Xiaomi mobile phone with this design. What are the characteristics of Red Rice Pro's photography today when dual-camera products are relatively mature? Let's explain it in detail.
In terms of parameters, Red Rice Pro is equipped with a13 megapixel main camera, using Sony IMX 258 sensor, and another 5 megapixel camera, using Samsung sensor. Different from the black-and-white+color dual-camera imaging scheme currently adopted by Huawei, Red Rice Pro's13 million main camera is responsible for imaging, and 5 million auxiliary cameras are responsible for recording the depth of field information of the picture to help the post-processing and presentation of photos.
Specifically, the dual camera principle of Red Rice Pro is similar to that of human eyes. The reason why human eyes perceive the three-dimensional properties of space is that human eyes observe the same object from different angles, resulting in visual differences, which are reflected in the three-dimensional space we see after being processed by the brain. The dual cameras of Red Rice Pro are like people's eyes, and the ISP built in Helio X25 is the brain. ISP processes the information captured by two cameras through a certain algorithm, thus giving the photos corresponding depth of field information. With this information, we can realize the interesting functions of blurring the large aperture background and focusing after taking pictures.
Here are some examples to help you understand the interesting functions brought by dual cameras.
In the camera's photo interface, there will be an obvious aperture mark, which will enter the dual-camera opening mode after opening. In this comparison, we chose different focus points before and after the same picture, which can easily realize the function of taking pictures first and then focusing.
Red rice Pro also provides the function of blurring the background with large aperture, ranging from F0.95 to F5.6 If the shot object has a layered feeling, the blurring effect of each gear will be very obvious. In addition, pictures with depth of field information usually have a large capacity, at least about 8MB.
It should be noted that this Helio X20/X25 chip adopted by Red Rice Pro integrates Imagiq image signal processor, which natively provides more support for dual cameras. Through real-time depth of field, real-time background blur can be realized, and what you see is what you get. In addition, the IMX 258 sensor used in the main camera natively supports phase focusing and contrast focusing, and the triangular focusing brought by the dual cameras makes the focusing options of Red Rice Pro more diverse. Imagiq image processor will also coordinate three focusing methods according to different scenes to realize hybrid autofocus and improve focusing performance.
Of course, how to speak with real proof? We choose Red Rice Note 3 (full netcom version) as the comparison object to see what improvements have been made in Redmi's flagship work Red Rice Pro.
In this contrast, we can clearly perceive the white balance tendency of the two. Red rice Pro is colder and blue is more flavorful. As for orange, it is not satisfactory, not as bright as red rice Note3. The red rice Pro on the left side of the screen has a slight overexposure tendency, which makes people feel uncomfortable, so in my opinion, red rice Note 3 is more pleasing.
This group can still perceive the difference in white balance between the two. By comparing the colors of the sky and turf, the green and blue of red rice Note 3 are more vivid and pleasing to the eye.
In the environment of large light contrast, both mobile phones have turned on HDR mode, and this part of Red Rice Pro obviously has certain advantages, especially at the junction of buildings and the sky. The exposure of red rice Pro is handled properly, and the railing on the roof can still be distinguished. In terms of hair color, Red Rice Pro is more natural, and Red Rice Note 3 is obviously purple. In the resolution of details, the two are actually indistinguishable, and both can meet daily use. Let's look at some samples of red rice Pro.
In terms of night scene, the brightness of Red Rice Pro is relatively high, and the colors of trees and building walls behind it are also recorded. Of course, it also sacrifices a certain picture purity, but it is still within the acceptable range.
In this set of details, the presentation of Red Rice Pro is more exquisite, recording the color of headlights and the text of number plates. However, Red Rice Note 3 is obviously insufficient, and the color of headlights is gone.
On the whole, Red Rice Pro has sufficient imaging during the day, and night imaging has certain advantages over Red Rice Note 3. With the help of dual cameras, you can take photos first and then focus, blur the background with large aperture and other functions, which increases the interest and playability. Unfortunately, the dual cameras did not play a decisive role in the image quality, and there is still room for optimization in the later stage, but it is undeniable that this is a good attempt of the Redmi series.
"6. A big advantage of Red Rice Pro: MIUI 8.
After iteration, MIUI has long been a leader in customizing ROM for smart phones, and it is a plus item for every generation of Xiaomi mobile phones. The newly released MIUI 8 further improved the interface, function and performance of MIUI, and was well received in the public beta stage. With the help of this red rice Pro, I also sorted out MIUI 8 to explain the author's impression of it. It should be noted that MIUI 8 pre-installed in the evaluation machine is a development version, and the mass production machine will also be pre-installed with MIUI 7.5 stable version for transition, which is expected to be upgraded in mid-August.
"The interface is lively and the dynamic effect is natural.
MIUI 8' s interface to the system is more vivid and bright in color selection, and large color blocks are used repeatedly, reflecting youthful vitality. The animation effect of the system has also been redesigned, which not only pursues the coolness of animation transformation, but also pursues the natural logic behind dynamic effects, such as the number that pops up from the keyboard when dialing, the interface shrinks and removes when hanging up, and the dynamic effect of the shredder that deletes notes.
"Perfect function, convenient and practical.
MIUI is famous for its timely and complete function updates. As a leap-forward upgrade, MIUI 8 has brought many fresh and practical functions, covering a variety of usage scenarios in life, and several functional points have impressed the author.
1, scan
The sweeping of MIUI 8 is, to a certain extent, an expansion of common text search, which integrates many functions of fate. Scanning is not only limited to daily bar codes and QR codes, but also supports scanning, translation, scanning search, scanning business cards, scanning documents and so on. According to the author's usage habits, Sweeping Litao has a very powerful function. When you see a favorite item, you can immediately sweep it, and the mobile phone can search out the price of the item in Taobao merchants, helping us make the most suitable consumption choice. For students and friends, the function of scanning questions may be more practical, supporting the answers of all subject questions from Grade One to Grade Three, and generating learning reports after use, further helping to consolidate knowledge points.
2, application, mobile phone in two places at once
MIUI 8 has a unique "separation" function, and this separation is not limited to the double opening of some social applications, but also allows the mobile phone to complete the "separation" in one step, that is, by setting different passwords/fingerprints to log in to different desktops, while the data between the two parts is also isolated and encrypted. Today, mobile phones hide a lot of our privacy, and this function will have more significance in some scenarios. For example, someone temporarily borrows a mobile phone, quietly enters a "visitor" account, and hides some relatively private applications, so as to protect privacy.
3. Other small features: long screen shots and calculators
The calculator has also been upgraded, and the calculation steps can be modified at any time. It also supports Chinese case conversion, exchange rate, individual tax, mortgage calculation, unit conversion and other calculations, which is very practical. It also adds a long screenshot function, which is not only a regular scrolling screenshot, but also can drag the area that needs screenshot up and down. It supports accurate cutting, marking and mosaic daubing, which is convenient for sharing and editing daily long emails and web pages.
"Advertising has been reduced and constantly optimized.
MIUI 7' s advertisement was repeatedly vomited. After actual measurement, the advertising problem in MIUI 8 has been improved. The weather, security center and information flow push in the calendar can be turned off manually, but some "stubborn advertisements" are still retained, which will not affect the overall use. Hongfeng, head of MIUI, also said that the current advertising is an exploration of business model, and users' complaints about advertising are largely due to the operational problems in the background of MIUI, which will continue to be optimized in the future to better integrate information flow with users' needs.
In addition, in this era of online celebrities and live broadcasts, MIUI 8 also keeps pace with the times, integrating Xiaomi Live, and will better combine the camera function of Xiaomi mobile phone in the future to bring more live effects. In terms of payment, MIUI 8 has also made great progress. At present, it has been confirmed that Alipay and WeChat will adapt to fingerprint payment one after another at the end of September, and MI Pay will also start internal testing in August. Because Red Rice Pro has no NFC function, there is no chance with MI Pay, which is a pity.
On the whole, MIUI 8 has many highlights and few advertisements, and there will be more perfect functions in the future, which is worth upgrading for Xiaomi users and a plus item for Red Rice Pro.
"7, evaluation summary
Red Rice Pro, as the flagship of Redmi, which is positioned higher than Red Rice Note, continues the consistent cost performance gene of Redmi series in hardware performance and pricing. CNC metal integrated body design and surface metal wire drawing treatment make Red Rice Pro gain high value, which can be regarded as a breakthrough for Redmi series mobile phones wearing the "thousand yuan benchmark" hat, and even refresh the customary impression of the outside world on Red Rice mobile phones. CNC metal integrated fuselage, this is the first time in Xiaomi mobile phone products.
Red rice Pro is Xiaomi's first mobile phone equipped with dual cameras, the first mobile phone in Redmi series with front-press fingerprint recognition, and the first mobile phone with organic light-emitting diode screen. Full Netcom 2.0, dual card dual standby, complete functional configuration, no obvious shortcomings. Especially, the dual cameras greatly improve the playability of the cameras on the premise of ensuring high imaging quality, which is the icing on the cake.
Finally, as the top chip in MediaTek this year, Helio X25 has made great progress and promotion in overall performance and function compared with the previous generation Helio X 10. Especially in CPU computing, thanks to the 10 core architecture, the computing power of Red Rice Pro is not far from that of Xiaolong 820. However, GPU performance is still a big shortcoming in MediaTek, and it is still difficult to cope with some large single-player games.
For most moderate users of mobile phones, the red rice Pro of 1499 yuan has outstanding technology and high cost performance, which is worth buying. However, for heavy users of mobile phones, especially heavy users of games, Red Rice Pro is not suitable.
