In 2013, when Xiaomi released the first red rice phone at a price that was 799 yuan, which seemed to be low at the time, perhaps no one could think that in just three years, the red rice series could bring over 100 million sales. Almost every ten people have a red rice mobile phone user, so the red rice series is also proudly called "national mobile phone" by Xiaomi. From the beginning of the year, Xiaomi has launched four red rice products, further subdividing the red rice series, forming the layout of red rice, red rice Note, and red rice pro. In the face of more and more product lines of red rice, Xiaomi timely combing the red rice series, can have a clearer understanding of the brand definition of red rice.
According to IDC data, the global smartphone market grew by only 0.5% in the first half of 2016. In the era of explosive growth of smart devices during the 2G to 4G process, as the mobile phone market gradually shifted from the incremental market to the stock market, For users, simply relying on “price/performance ratio†can no longer meet their higher demand for smart devices. For manufacturers, the mode of selling only by e-commerce channel is also under increasing pressure. It can be seen that the appointment of spokespersons and continued deep cooperation with China Mobile to expand channels, has been the "extremely cost-effective" red rice mobile phone has been clearly on the road to transformation. On such a node, Xiaomi and China Mobile launched the red rice Note4, its significance is self-evident. As a pioneer in the development of the red rice series to develop offline channels, what is the performance of Redmi Note4, we continue to look at the evaluation.
Hardware parameter list
Hardware part, Redmi Note4 uses MediaTek Helio X20 processor, with 3GB+64GB of memory, 5 million +13 million pixel camera, 4100mAh high density battery, support Alipay fingerprint payment after upgrading MIUI 8, and adopts integrated all-metal back Shell (non-three-stage design), nano-injected antenna, can support dual card dual standby, full Netcom 2.0. From the first point of view, it is still familiar with the red rice, or the standard thousand yuan high. And in appearance, Redmi Note4 made some changes, and the non-three-section true-integrated all-metal back shell also left a good impression on the author. It can be seen that after the comprehensive upgrade of Redmi Note3 (Standard Edition), Redmi Note4 is still a very cost-effective product in the thousand yuan machine.
Analysis of industrial design of appearance
A month ago, Red Rice Pro was released as the flagship model of the red rice series. For the first time, the integrated metal body, combined with the brushed texture, raised the appearance of the red rice mobile phone to a higher level. The red rice Note4 is mainly called "National All-Metal", which naturally retains the craft level of Red Rice Pro. It has certain highlights, and the following is an in-depth interpretation.
Overall, Redmi Note4 adopts the regular design style of rounded rectangles, and the front design of the fuselage is simple and has no decorative elements. Equipped with a 5.5-inch full HD screen, covered with a layer of 2.5D arc-rimmed glass, the black-edge control is quite satisfactory, and there is no obvious abrupt sensation on the white model, which is an acceptable range. At the junction of the screen and the metal body, Red Rice Note4 is wrapped with a layer of white polycarbonate cushioning material to give the screen full protection.
Red Rice Note4 uses the same CNC integrated metal body as Red Rice Pro, which has a qualitative leap compared to the red rice Note3 stamped metal body. Specifically, the body of the Red Rice Note4 is cut, drilled, and polished by a single piece of metal through a CNC (CNC machine tool), and then the antenna signal overflow band is completed by the nano-injection process, and finally the integrated metal casing is obtained, and the cost is obtained. Not cheap. The body of Red Rice Note3 is made of metal plate punched with punches. The upper and lower ends are usually spliced ​​with plastic material to form our common three-section metal body. Compared with the two, the metal fuselage structure of Redmi Note4 is stronger and more integrated, and can achieve a very high proportion of metal, which directly echoes the theme of “national all-metalâ€.
In addition, in order to preserve the metal texture, Red Rice Note4 also uses sand blasting technology, using 205 ceramic blasting, which not only retains a certain metallic luster, but also makes the matte touch on the back of the machine more delicate, and moderates it to some extent. The 5.5-inch size and 175-gram weight give the discomfort.
Redmi Note4 uses a more popular symmetrical design, including the earpiece on the front side, the camera, the light distance sensor, the micro USB port on the bottom and the speaker. Most of the elements are symmetrical and visually more balanced. The only asymmetry appeared on the top of the phone. The headphone hole, infrared sensor, and noise reduction MIC could not coordinate the symmetrical layout.
Summary: It should be said that the appearance of Redmi Note4 is quite bright, and the more advanced metal body technology has been chosen. The look and feel are significantly improved, and the advantages are obvious in the same price mobile phone. More valuable is that the author finally saw the inheritance of Xiaomi's design elements in this product, such as the curved design of the sides of the back of the fuselage, since the appearance of Xiaomi Note, appearing in Xiaomi 5, millet Max, Red Rice Pro and Red Rice Note4. Obviously, Xiaomi is not only in the process of finishing the product, but also in designing his own direction, and has already begun to take shape.
Hardware performance analysis:
Since the birth of Red Rice, it has been positioned in the name of the most "cost-effective" thousand-yuan mobile phone. "Price" refers to low price, and "sex" is undoubtedly representative of performance. Therefore, the hardware performance of each red rice phone has become a part of many manufacturers and users, because this is likely to represent the hardware standard of the thousand yuan machine for a period of time. In terms of hardware, Redmi Note4 uses MediaTek MT6797 (Helio X20) SoC. Based on TSMC's 20nm HPM process technology, the chip integrates the Mali-T880MP4 graphics processor and is equipped with a seven-mode full-band network modem, positioning it as a cost-effective civilian flagship processor.
As the processor with the most core core, the X20 introduces a three-series ten-core architecture. Simply put, the X20 divides 10 cores into three clusters (2xA72 4xA53 4xA53). The two sets of A53 architectures have a dominant frequency of 2.0GHz and 1.4GHz, and the A72 architecture has a clock speed of 2.5GHz. The three clusters pass through the MCSI interconnect bus. The connection between the two is performed, and the CorePilot 3.0 heterogeneous operation is used to perform real-time transfer between the cores. To put it simply, different clusters correspond to different working states. For the full power of the mobile phone, you can call the large core processing. When you use it lightly, you can use a small core. For medium load, you can use four 2GHz cores. Upon completion, each core can also adjust the clock frequency.
In addition, the size can be adjusted arbitrarily, and the processor can adapt the application according to the actual use condition to achieve the most suitable state for the application. In short, the three-set ten-core architecture makes the mobile phone more intelligent in the usual use, the use of the processor is more detailed, and the power consumption ratio is improved. In the actual running test, the single-core performance of the X20 is 1653 points, and the multi-core performance is 5126 points. From the perspective of CPU performance, the single-core performance is roughly equivalent to that of the Snapdragon 652, and with the advantage of quantity, the multi-core running score is even better than the Snapdragon 652.
In addition, in terms of graphics processing, the Helio X20 uses the Mali-T880, which has almost no change in architecture, specifications and T760. It supports up to 16 shader cores, and the L2 L2 cache size is up to 2MB. The difference is that the T760 is developed for the 28nm HPM process, while the T880 is based on the 16nm FinFET process. From a process perspective, the T880 leads the T760 generation. Due to the improvement of the process, the T880 will increase the maximum frequency from 650MHz to 850MHz; the triangle fill rate will be increased from 1300Mtri/s to 1700Mtri/s; the pixel output rate can reach 13.6Gpix/s, although it is improved compared to the T760 frequency, but Thanks to the upgrade of the architecture, power consumption has been reduced by 40%.
In the GFXbench test, 1080P Manhattan scored 16Fps off screen, 1080P Tyrannosaurus off screen is 17Fps, and Adreno's GPU is slightly different, but compared to the T760 has made good progress.
Summary: On the whole, horizontally compared to the current price of the same product, Red Rice Note4 can still become the performance flagship product in the thousand yuan machine. From the actual performance, X20 is the flagship product of MediaTek's current generation processor, and even slightly exceeds the data processing of Qualcomm Xiaolong 652. However, in terms of graphics, there are still some gaps between Mali and Adreno. Among them, the X20 may be slightly lacking in heavy games. The balance between performance and power consumption of the X20 is more in line with the user's need for practical use.
MIUI 8 system interpretation
Since the release of MIUI in 2010, it has undergone iterations, and the global activation volume has exceeded 200 million, which has become the core competitiveness of Xiaomi. Just two days before the release of Redmi Note4, MIUI ushered in a leap-forward upgrade that combines all aspects of design, functionality and performance enhancements to iteratively to MIUI 8. And this red rice Note4 is also the first mobile phone pre-installed MIUI 8. In this part of the article, we use Redmi Note4 to interpret some of the new features of MIUI 8.
New interface design, beautiful colors
MIUI 8 has a lot of redrawing on the interface of the system. Its design is inspired by the kaleidoscope of change. On the one hand, it pursues the bright and vivid vitality of color, on the other hand, it pursues the natural change of color and reflects the agility. For example, the notification bar can be automatically changed according to the weather. Change the color tone, calendar, tape recorder, weather and other software that comes with the scene.
Perfect function and better use
MIUI is well-known for its comprehensive feature update. As a leaping upgrade, MIUI 8 brings a lot of fresh and practical functions, covering a variety of usage scenarios in life, mainly focusing on the following functional points.
1, application, mobile phone avatar
MIUI 8's unique "divided" function is divided into two levels. The first level of the avatar is the application avatar, which is to achieve the dual opening of most applications. There are two WeChat, two QQ, two Weibo and any other in the mobile phone. A software that involves account login, and the data between the dual-open applications does not affect each other and can run at the same time. This design resolves the embarrassment of one person and multiple accounts, enabling better switching of identities in work and life scenarios. For mobile game enthusiasts, you can also switch between large and small.
MIUI 8's second-level avatar is the mobile phone avatar, that is, by setting different passwords/fingerprints to log in to different desktops, and the data between the avatars is also isolated and encrypted. Today, when mobile phones hide our many privacys, this feature will have more meaning in some scenarios. For example, when someone borrows a mobile phone, they will quietly enter the “visitor†account and hide some of the more intimate applications, which will not be noticed. It also protects its privacy.
2, a powerful sweep
The sweep of MIUI 8 is also a highlight. It is not limited to daily barcodes and QR codes. It also supports sweeping, translating, sweeping search questions, scanning business cards, and scanning documents. In terms of the author's usage habits, the function of sweeping Amoy is very powerful. When you see the favorite items, you can scan the price of the item in Taobao merchants and help us make the most suitable consumption choices.
For student friends, the sweep function may be more practical. The problems encountered in the homework will be swept away immediately, and the mobile phone will be able to give detailed troubleshooting steps, support the answers to the full-question questions of the first to the third year, and generate learning reports after use to further help to consolidate the knowledge points.
3, multi-function calculator
In MIUI 8, the calculator is upgraded to a full-featured calculator that combines utilities such as calculating mortgages, taxes, provident funds, units, and exchange rates for a variety of computing scenarios. For example, when we travel abroad, Haitao needs foreign currency exchange rate conversion, the calculator supports conversion of multiple currencies, the exchange rate is also updated in time, and the conversion is intuitive and fast. For the majority of office workers, it is also very practical to calculate the salary tax, bonus benefits, and mortgage payments.
In addition to the powerful integration of functions, MIUI 8's calculator has also been greatly improved in the experience. Each number entered is clearly presented in every operation performed. In order to cope with the input errors of individual numbers and operands, the calculator supports the modification of the calculation steps at any time, which makes the calculation process safe. In addition, the calculator also supports digital Chinese uppercase conversion, which resolves the problem of forgetting words when reimbursing the replenishment.
4, long screen shot
MIUI 8 has added a long screen capture function. It is not only a regular scrolling screen. The user can adjust the speed and position of the long screen by hand sliding, find the area that needs to be screened, and achieve accurate screen capture. In addition, MIUI 8 also added graffiti and mosaic functions to facilitate the next step of editing and editing the screenshot.
It should be said that the appearance of the long screen capture function has many practical meanings. Imagine, if there is no such function, we intercept webpages, emails, social software (WeChat, QQ, etc.) chat records, etc., but also through a few screenshots to piece together, no doubt added a lot of trouble, and the final rendering effect is not ideal . The long screen function provided by MIUI 8 solves the above problems well and is satisfactory in terms of operation and rendering effects.
Advertising improvement, continuous optimization
The advertisements of MIUI 7 have been repeatedly spit out. After the actual measurement, the advertising problem has been improved in MIUI 8. Weather, security center, calendar information flow can be manually selected to close, but still retain some "hidden and stubborn ads", such as album page ads on music play pages, ads on the lunar pages below the calendar, does not affect the overall use. MIUI official Hong Feng also said that the current advertising is a business model exploration, the user's complaints about advertising are largely due to the operational problems of the MIUI back office, the future will continue to optimize, the information flow and user needs will be more Good combination.
In addition, MIUI 8 equipped with Redmi Note4 has made progress in fingerprint payment and has already supported Alipay's fingerprint payment. It is expected that WeChat's fingerprint payment will be completed in September. MIUI will continue to improve. It is reported that screen recording, split screen and other functions are already in progress, and the future is worth looking forward to. Overall, MIUI 8 features a lot of highlights, advertising problems have improved, there are still some stubborn ads. Simply, the MIUI 8 is still a plus item for Redmi Note4.
Photo analysis:
For some users who purchase a thousand yuan machine, there may not be too high requirements in terms of performance, but with the popularity of social mobility, no matter what kind of users have a certain degree of expectation for taking pictures. Red rice Note4 uses 13 million pixel camera (Samsung or OV), F2.0 aperture, equivalent focal length 3.5mm, supports PDAF phase focusing function, this part of the article, let's take a look at the photo level of Redmi Note4.
â–²Outdoor proofs
In the day when the light is sufficient, the outdoor rice sample, the image quality of the red rice Note4 is acceptable, inheriting the characteristics of Xiaomi's consistent white balance and warmth, especially for the red adjustment of the teaching, the color of the photo is rich and vivid. For the difficult to grasp the green restore is also in place, but the entire picture is not transparent enough. This is also the characteristic that some thousand yuan machines are used to, and the picture quality is acceptable but has no special features.
â–² indoor proofs
Indoor proofs, due to lack of light, red rice Note4 by pulling ISO to 683, using 1/30S shutter speed, so that the picture purity is reduced, the whole picture is somewhat white, but this adjustment ensures the brightness of the photo under low illumination . Generally speaking, in low light, the priority of the picture is greater than the picture quality, so it is not difficult to understand that the red rice Note4 adopts such adjustment.
â–²Macro proofs
In terms of macro, the performance of Redmi Note4 is quite satisfactory. The whole picture can clearly explain the part being photographed, and the background blur is more natural, but the stereoscopic effect of the picture is slightly lacking.
â–² night scene proofs
In terms of night scenes, Redmi Note4 is relatively flat. Although the brightness of the picture is not bad, the ISO is too high, so that the sky part of the whole picture is more noisy, and there is almost no dark detail on the high floor.

Summary: The photographing level of Redmi Note4 is acceptable in the thousand yuan machine. When the light illumination is sufficient, the white balance is more accurate, and the red and green which are more difficult to express have a good restoration. The whole picture is warmer. This is also the consistent style of Xiaomi's photos. In the case of light, there may be insufficient brightness of the picture or loss of part of the picture quality in order to maintain the brightness of the picture. In terms of night scenes, the performance of Redmi Note4 made us somewhat disappointed, and the filming rate was not high enough.
Evaluation summary:
In the era of stocks, it is difficult to continue the brilliant sales just by relying on the price-performance ratio. Even the red rice series, which has always relied on products, has begun to hire spokespersons to establish a brand image. On Redmi Note4, Xiaomi announced that it will conduct a unified agent with China Mobile and use China Mobile's more than 3,000 offline stores to sell. This is an important step for Xiaomi to re-precipitate offline when facing the bottleneck of online channels. When we look back at the development process of the red rice mobile phone, we can see such data. The first red rice released in 13 years, with China Mobile, the total sales reached 22.07 million units; the first generation of Red Rice Note, cooperated with China Mobile , 27.53 million units. As a popular mobile phone with low price and high distribution, the attributes of red rice are almost perfectly matched with the offline channels that are mobile all over the country.
Back to the product, this product of Redmi Note4 has chosen the CNC integrated metal body which is rare in the thousand yuan machine. The fuselage process has been significantly improved compared with the past products; the configuration also continues the strong style of Xiaomi, equipped with the flagship of MediaTek The Helio X20 processor, 3GB+64G storage combination, uses a 5.5-inch large screen to configure fingerprint recognition, and the advantages of the same price segment are obvious. With the release of MIUI 8, Redmi Note4 has become the first model pre-installed with MIUI 8, which is easier to use. Although the performance in the imaging part of the camera is somewhat unsatisfactory, it does not hide, and the overall price is still the most worth buying.
