Where is the down frequency of Xiaomi note?

It is the simplest and most effective way to measure the development trend of a mobile phone brand and observe its sales volume. According to the statistical report of the research company Sino, the total sales volume of millet in the first half of 20 16 was about 23.66 million units, which was only one third of the total sales volume of 7 15. This makes it impossible for Xiaomi to re-examine the current mobile phone market and change its product strategy with the times. To this end, Xiaomi began to pay attention to the laying of offline channels, invited celebrities to speak for themselves, redefined the brand image, and launched a series of flagship products such as Xiaomi 5s/ Xiaomi 5sPlus/ Red Rice Pro. However, although these products have their own selling points, it is difficult to make an explosive image because of outdated design. Then the important task of promoting the brand and driving sales growth naturally falls on Xiaomi Note2, the protagonist of this evaluation. From the time node and product cycle of product release, Xiaomi Note2 Standard Edition can be defined as the flagship mobile phone of the year. During this period, the capacity of upstream suppliers tends to be stable, and mobile phone manufacturers can choose a wider range of customization. So we saw many exciting upgrade points on Xiaomi Note2. In addition to the top hardware parameters, the most amazing are the hyperboloid display and the double-sided 3D glass body. It is no exaggeration to call it the most beautiful Xiaomi mobile phone in history. Appearance: In addition to the high configuration of Xiaomi gene, Xiaomi Note2 uses a 5.7-inch organic light-emitting diode flexible screen for the first time, and the addition of dual curved surface screen makes Xiaomi Note2 the most valuable Xiaomi mobile phone in history. Compared with international big-name models such as Samsung GalaxyS7edge and Note7, which also adopt hyperbolic screen design, it does not fall into the wind. In this part, we will analyze the design of Xiaomi Note2 in detail. On the front of the fuselage, the screen size of Xiaomi Note2 is 5.7 inches, and the resolution is 1920* 1080. The design of hyperbolic screen makes Xiaomi Note2 present an excellent look and feel, with unlimited vision. Although this design is not the first time, the first time it is used on Xiaomi mobile phone, it will still make people sincerely sigh that Xiaomi has made rapid progress in design, and it is no longer the Xiaomi mobile phone that takes "no design is the best design" as its creed. There are light distance sensors, headphones and front camera at the top of the front of the fuselage. The front panel of the fuselage and the back of the fuselage are the same in color and technology, and will be slightly blue under indoor light, showing a beautiful shiny metallic texture. On the other hand, the joint of the two materials will often become the hardest hit area for workmanship. The joint of Xiaomi Note2 screen protection glass and metal middle frame is very close, with neat edges, which reflects the standard as a flagship product. At the bottom of the front of the fuselage, Xiaomi Note2 uses a push-type fingerprint recognition button. Different from the long and narrow Home button used by Xiaomi 5, this Home button of Xiaomi Note2 has been adjusted, with a larger area and a more harmonious visual appearance. It can be seen that the Home button of Xiaomi Note2 is not consistent with the color of the fuselage. The reason is that the fingerprint identification key surface of Xiaomi Note2 is made of ceramic material with high dielectric constant, which is the most ideal covering material at present. However, the physical properties of ceramic materials are stable and it is not easy to do coloring treatment, which is the most direct reason why the color of ceramic materials is inconsistent with the fuselage. On both sides of the Home button, there are still two small white multi-task keys and return keys, which will light up after touching, and users can turn them off by themselves in the system settings. On the back of the fuselage, Xiaomi Note2 uses a large area of glass and is also a hyperboloid design. Xiaomi calls it 3D glass. On the one hand, it optimizes the grip of the edge, on the other hand, it also brings a more shiny translucent texture. In addition, everyone has noticed that the glass cover of Xiaomi Note2 is not a simple monochrome treatment. In different lighting environments, it will show different colors and have a strong metallic texture. The official has not introduced the process in detail yet, but it is very similar to the film pasting process used by Samsung GalaxyS6 for the first time in terms of perception. Simply put, there is a special layer of color reflective material under the glass cover, which will show different colors under different light. Everyone should know that the USBTypeC interface has been rapidly popularized in the past. Compared with the traditional MicroUSB interface, it can provide greater charging current and faster data transmission speed, with obvious advantages. Xiaomi Note2 uses USBTypeC interface. The speakers and microphones distributed at both ends of the bottom of the fuselage are symmetrically designed and look simple and unified. 3.5mm headphone jack, noise reduction Mic and infrared transmitter are distributed on the top of the fuselage. MIUI has built-in universal remote control APP, which can easily control traditional household appliances such as air conditioners and televisions. At present, the layout of Mijia smart home has been very extensive, which is basically a basic function of Xiaomi mobile phone. As for the camera, Xiaomi Note2 adopts Sony's IMX3 18 camera sensor with 22.56 million pixels, F/2.0 aperture and 80 wide angle, which can present more picture details. Other parameters, the camera supports hardware-level 4K video anti-shake, and the built-in three-axis gyroscope can detect jitter at high speed and make real-time compensation. A metal protective ring is designed around the camera to reduce the risk of lens wear. The camera is equipped with a dual color temperature flash. Summarizing the appearance, the overall design and workmanship of Xiaomi Note2 have reached a high level. The design of the front hyperbolic screen and the rear 3D glass really adds a lot of color to this phone. In terms of appearance, Xiaomi Note2 even subverts our usual inherent impression of Xiaomi mobile phone and is a strong successor of Xiaomi Note. "The most beautiful Xiaomi mobile phone" is well deserved. Interpretation of hardware performance: Still born for fever With more and more functions that smart phones can carry, people pay more and more attention to the experience of using mobile phones. There is a saying that the hardware performance of the mobile phone has surpassed the function itself at this stage, so the hardware performance has become no longer important. But in my opinion, excellent hardware configuration is always the basis of pursuing user experience. The so-called "soldiers and horses have not moved food and grass first" and "don't collect running points" can only be the most intuitive display of mobile phone performance for manufacturers to consumers. With the guarantee of hardware performance, the product can have a better user experience. Room for improvement. Then in this part of the article, let's take a look at the performance of Xiaomi Note2, which once again hit the high-end market. Xiaomi Note2 is equipped with standard Snapdragon 82 1 processor and 14nmFinFET process. The standard version uses 4GB+64GB of memory. Regarding Snapdragon 82 1, I believe everyone is familiar with it. Almost every manufacturer's flagship machine has used this processor. From the naming point of view, Snapdragon 82 1 can be regarded as a comprehensive upgrade of Xiaolong 820. Snapdragon 82 1 still adopts Kryo, a 64-bit micro-architecture developed by Qualcomm. The main frequency of the two large cores is increased from 2.2GHz to 2.4GHz, and the main frequency of the two small cores is increased from 1.6GHz to 2.0GHz, which means that the CPU can steadily improve its running speed through the evolution of technology. And the performance is improved by 10%, so that faster application startup speed and smoother use experience can be obtained. Of course, compared with other high-end processors on the market, Snapdragon 82 1 can provide comprehensive solutions in other aspects of the processor. Snapdragon 82 1 is still composed of CPU, GPU, VPU, Hexagon680DSP, DPU, X 12LTE baseband, SpectraISP and LPDDR4 memory. Snapdragon 82 1 has built-in Adreno530. Compared with the previous generation Adreno430, the graphics processing performance, computing power and power consumption are improved by 40%, and the running speed is increased by 5%. It supports OpenGLES3. 1+AEP and Vulkan. In the future, with the change of game programming framework, the previous products will also get a good experience. With the help of SpectraISP, the dual-image signal processing ability has also been improved, bringing faster focusing speed, stronger low-light photography performance and higher pixel support. On the network side, Snapdragon 82 1 is equipped with X 12LTE baseband, supporting Cat 12/ 13, with downlink rate of 600Mbps and uplink rate of 150Mbps, and the native baseband supports six-mode full frequency. It is worth mentioning that Xiaomi Note2 is also divided into two versions: the National Bank version and the international version. In detail, the Bank of China version still supports the network support of mobile, China Unicom and telecommunications from 2G/3G/4G, but it does not fully support the international version in specific frequency bands. The global version supports all the current 6-mode 37-frequency. During the whole charging process, 80% of the electricity starts to adjust the current, and 85% enters trickle charging. Xiaomi Note2 is equipped with 4070mAh battery, which supports Qualcomm QC3.0 fast charging. QC3.0 adopts the intelligent negotiation of optimal voltage developed by Qualcomm, and takes 200mV as the step, which supports the dynamic adjustment of the voltage from 3.6V to 12V on the mobile phone, so that the charging voltage can be dynamically adjusted when the mobile phone is charging, so as to achieve the expected charging current and improve the charging efficiency. We also tested the charging of Xiaomi Note2: the total charging time 1 hour is 54 minutes, the average charging voltage is 6.26V, the total power is adjusted between 15W- 16W, and the mobile phone drops to10w-/kloc-0 when it is charged to 80%. After testing, the charging time of Xiaomi from 0-50% is 37 minutes in total. In general, the charging speed of Xiaomi Note2 in the sprint stage is still excellent. In terms of performance score, Xiaomi Note2 scored 14 1250 in Ann Bunny, 1804 in Geekbench4 single core and 434 1 in multi-core, which can only be said to be normal for Snapdragon 82 1. In the graphical test platform GFXBench, Xiaomi Note2 scored 44Fps in the off-screen test of Manhattan 1080P, which is obviously ahead of PowerVRGT7600 equipped with A9, and still has a certain gap with this year's powerful A 10Fusion. For the current processors, the high performance brings challenges to the temperature of mobile phones, especially Android phones. The frequency reduction caused by the fever of the mobile phone also makes the mobile phone with high initial frequency unable to run stably for a long time, which is one of the reasons why users complain that there are too many cards in normal use. We also tested the fever of Xiaomi Note2, and simulated two modes of daily use and high performance. In the high-performance link, after several rounds of running the software, the highest temperature of Xiaomi Note2 appears in the middle of the top of the fuselage screen, and the highest temperature is 36.8℃, which is only warm in the hand and completely acceptable. In the simulation of the usual scene, Xiaomi Note2 has almost no fever, and the highest temperature is still in the middle of the screen, and the highest temperature is 33.6℃. Overall, this result is very good for a Snapdragon 82 1. In addition, Xiaomi Note2 uses a 5.7-inch OLED screen with a resolution of 1080P. Because of the well-known pixel arrangement problem in Pentail, Pentile reduces the number of sub-pixels by sharing sub-pixels with adjacent pixels, so as to achieve the effect of simulating high resolution with low resolution. In this way, when fine content needs to be displayed, the clarity of screen content will be greatly reduced, resulting in small fonts not being clearly displayed. In order to make up for the color problem, when the color division area is displayed under Pentile technology, the division line will produce jagged lines twice the actual pixel spacing, that is, jagged edges will be produced. We also show the difference between the two through a simple screen remake. Xiaomi Note2 screen PPi 387. Because OLED screens share pixels, the actual PPI should be close to 2/3 of the theory. Therefore, in actual perception, the image edge will still slightly affect the display effect. MIUI8 system experience: still the core part of Xiaomi. Xiaomi Note2 is pre-installed with the latest MIUI8 system. As the core competitiveness of Xiaomi, MIUI has always enjoyed a good reputation. The cumulative number of users worldwide exceeds 200 million, which shows the recognition of consumers. As a mobile phone focusing on business applications, Xiaomi Note2 is Xiaomi's first hyperbolic screen mobile phone. Has MIUI8 been adjusted accordingly? In this part of the article, we made a detailed interpretation. The theme of luxury echoes the business style. MIUI8 has done a lot of redrawing on the interface of the system, and the design inspiration comes from the ever-changing kaleidoscope. On the one hand, it pursues the brightness and vitality of color, on the other hand, it pursues the natural change of color to reflect agility. For example, the notice bar can automatically change color according to the weather, and the software such as calendar, tape recorder and weather can also change color according to the situation. MIUI8 has added the function of lock screen pictorial, which can automatically change the lock screen wallpaper according to users' preferences, bringing freshness and embodying taste. In addition to the default theme, MIUI8 also provides four sets of customized themes, such as luxury, boys, girls and goddesses. Among them, the luxury theme is mature and complements the positioning of Xiaomi Note2. System+application doppelganger MIUI8 supports the dual doppelganger of system layer and application layer. At the system level, MIUI8 can log in to different desktop spaces by setting different passwords/fingerprints, so as to carry out different operation management. Of course, data in different spaces are also isolated and encrypted. Business people pay special attention to personal privacy, so this function will be more meaningful. On the one hand, users can hide their personal property and work-related applications in one space to create a relatively safe and isolated operating environment. On the other hand, when someone borrows a mobile phone temporarily, they quietly enter the preset "guest" desktop space, hide relatively private applications, and protect their privacy. In terms of application busyness, MIUI8 can realize the busyness of most applications, that is, there are two WeChat, two QQ, two Weibo and any software related to account login in the mobile phone at the same time, and the data between the two open applications does not affect each other and can run at the same time. This design solves the embarrassment of multiple accounts of one person, and can better switch identities in work and life scenes. Long screen capture improves efficiency MIUI8 adds a long screen capture function, which is not only a regular scrolling screen capture, but also allows users to adjust the speed and position of long screen capture by manual sliding, so as to find the area that needs screen capture and realize accurate screen capture. In addition, MIUI8 also adds graffiti and mosaic functions, which facilitates the next processing and editing of screenshots. It should be said that the appearance of long screen capture function has many practical significance. Imagine that without this function, we would intercept web pages, emails, social software chat records and so on. And we have to piece it together through a few screenshots, which undoubtedly adds a lot of trouble and the final rendering effect is not ideal. The long screen capture function provided by MIUI8 solves the above embarrassment well, and it is more efficient in the operation process and the rendering effect is satisfactory. Multi-function calculator practical MIUI8 integrates a full-function calculator, integrates practical tools such as calculating mortgage, individual tax, provident fund and unit conversion, and is suitable for various calculation scenarios. For example, business people often face exchange rate calculation between currencies. In the face of unfamiliar currency units, some prices cannot be reflected in time. With Xiaomi's calculator, the exchange rate can be quickly converted to support multiple currencies. The exchange rate is also updated in time, so they are no longer confused. For the majority of office workers, the calculation of salary tax, bonus and welfare, mortgage payment, etc. It has also become clear and practical. Other targeted adjustments are worth mentioning. MIUI8 also pre-installed Microsoft office suite, including Word, Excel, PowerPoint and Outlook, covering the most commonly used office software. In addition, MIUI8 is also optimized for the problem that the curved screen touches the edge by mistake. In actual operation, it can well shield the wrong touch of the author's palm without affecting the normal operation. Support Xiaomi Payment Xiaomi Note2 supports Xiaomi Payment, and adopts NFC scheme to realize card reading, card writing, analog card and P2P mode. It not only supports simulated bank card payment, but also supports simulated bus card payment. This means that you don't even have to bring your wallet when you go out with Xiaomi Note2. Bank cards and bus cards have been handled. At present, there are as many as 20 Xiaomi payment cooperative banks, and there are 6 cities and regions supported by bus cards, including big cities such as Beishangguangshen and Shenzhen, and more cities will be opened through software upgrades. Overall, MIUI8 equipped with Xiaomi Note2 is still a good system. The only regret is that there is no self-luminous characteristic for hyperbolic screen and organic light-emitting diode screen. I also look forward to bringing more surprises through subsequent system upgrades. Photo test: What is the strength of 23 million pixels? Xiaomi Note2 is not equipped with the currently popular dual cameras. Its main camera adopts Sony IMX3 18 sensor, which can support up to 22.56 million pixel photos. The CMOS area is 1/2.6 inches, the unit pixel size is 1μm, and the maximum aperture is F2.0 The biggest highlight of this CMOS is its support for phase and contrast compound autofocus, which can shorten the focusing speed to 0.03 seconds at the earliest. The main camera is slightly convex. In addition, Xiaomi Note2 does not support OIS optical image stabilization, and instead uses three-axis electronic image stabilization. Electronic anti-shake can be compensated and corrected by algorithm, thus achieving the purpose of image stabilizer. Its advantage is that it can reduce the thickness of CMOS, which is more in line with the customization requirements of thin and light mobile phones. It is worth integrating that Sony IMX3 18 integrates the autofocus system and the anti-shake system into the DSP of the processor, which can greatly reduce power consumption and save electricity. As for the specific performance, we analyze it by comparing it with the sample of iPhone7Plus. In the outdoor environment, resolution contrast Because Xiaomi Note2 is equipped with a higher pixel camera, it has an inherent advantage in the resolution of photos, and the pixel size of the final photos is also larger. So when two proofs are enlarged at the same time by 100%, Xiaomi Note2 can get more details. In the outdoor environment, the adjustment of white balance contrast white balance has always been Apple's traditional strength, and it is also the reason why major evaluation agencies are willing to choose it as the comparison benchmark. In contrast, Apple's white balance adjustment style is more inclined to restore the original appearance of the real thing, while Xiaomi Note2 is not much different from iPhone7Plus as a whole, but it is slightly blue when carefully observed. However, from the perspective of pure visual perception, because Xiaomi Note2 makes the sky bluer, the proofs are indeed more pleasing to users. In the outdoor environment, the macro contrast of the proof mainly tests the background blur ability of the camera when shooting close-range. Since the aperture of iPhone7Plus is F 1.7, which is larger than Xiaomi Note2, the blur ability will be slightly stronger. From the comparison of actual proofs, the same is true. However, it is worth noting that Xiaomi Note2 is relatively excellent in detail performance. After enlarging the sample, you can still see the residual spider silk on the petals. In the outdoor environment, close-up comparison of proofs Through the author's actual experience, although the proofs taken by Xiaomi Note2 in the outdoor environment are not much different from those of iPhone7Plus, there is still much room for improvement in software optimization. Its photometric accuracy needs to be improved, and the samples taken are slightly dim. In the indoor environment, the color comparison of the proofs In the indoor environment, the color performance of Xiaomi Note2 is obviously not as good as that of iPhone7Plus. However, thanks to the far-ahead number of pixels, Xiaomi Note2 can get a wider shooting field and more delicate performance than iPhone7Plus at the same shooting angle. The proofs obtained in this way are clear and convenient for later cutting and composition adjustment. In the outdoor environment, the color contrast of the proofs is very limited at night, and if the purity of the picture is guaranteed, the brightness of the picture will be reduced; If the brightness is raised blindly, the noise will increase. Therefore, according to the hardware parameters of CMOS, choosing a suitable balance point has become the key to algorithm optimization. In contrast, the picture brightness of Xiaomi Note2 is higher, while the iPhone7Plus is slightly darker, and the color performance is slightly dimmer than that of Note2. This round of Xiaomi Note2 can be said to have pulled back a city. In the outdoor environment, self-luminous object sample comparison From the close-up shooting scene at night, we can see that the white balance adjustment of Xiaomi Note2 is obviously different from that of iPhone7Plus, and the overall picture is obviously cold. When the focus is selected on the self-luminous object, the background brightness of the object is darker than that of the iPhone7Plus. The main reason for this problem lies in HDR algorithm, which can be effectively improved by algorithm debugging in the later stage. During the experience, I was deeply impressed by the focusing speed of Xiaomi Note2, because the iPhone7Plus is prone to a long-term "bellows pulling" phenomenon during the focusing process. For Xiaomi Note2, when your finger just clicks on the screen, focusing can be completed immediately, very quickly. Although from the final test results, there is still a certain gap between the overall camera level of Xiaomi Note2 and iPhone7Plus. However, the main reason is that the optimization of Sony IMX3 18 COMS is not mature enough. I believe that in the future, with the update of software version, the camera level of Xiaomi Note2 will be by going up one flight of stairs. Evaluation summary: Re-seize the high-end market This year, the mobile phone market has changed from an incremental market to a stock market, and the purchase method of users has gradually changed from online to offline. No matter which channel is online or offline, it is difficult for a brand to survive vigorously. Xiaomi has gradually returned to rationality from the barbaric growth of the previous two years. The cities covered by Xiaomi House are gradually increasing, and the software content realizes resource integration. The perfection of ecosystem and after-sales service can provide a set of perfect and humanized solutions for users who buy Xiaomi mobile phones, thus comprehensively improving the user experience. Under the background of the arrival of capital winter and the slowdown of domestic economy. OPPO and vivo gained the upper hand of Xiaomi in the first half of the year with their advanced brand marketing and strong penetration of the offline market. Letv relies on rich content ecology and strong capital operation ability to achieve the ultimate cost performance of mobile phones, and is also assigned to the "cake" in Xiaomi's hands. Compared with the above, Xiaomi has been somewhat weak due to the rapid growth in the previous period. However, due to the accumulation of a large number of user bases, the software system has almost reached the point where it is difficult to meet chess players. For users, this has subtly increased their use of Xiaomi mobile phones. Xiaomi Note2 has greatly stimulated Xiaomi's loyal users and will become their first choice when changing machines. But as far as products are concerned, Xiaomi Note2 is indeed a rare masterpiece in domestic mobile phones. Needless to say, the hardware configuration is naturally the top level in the industry. HIFI, NFC and infrared sensor are all available, and the battery capacity of 4070mAh also ensures its endurance. The experience of MIUI is also an advantage that Xiaomi has always been proud of. So no matter from the inside out, or even from the price, it is difficult for you to find problems. This is a well-balanced mobile phone, and it is also a mobile phone that is biased towards public aesthetics, and these two points are the sufficient conditions for creating an explosive product. From our experience, the biggest advantage of Xiaomi Note2 lies in its exquisite and glass-like industrial design. In addition, whether it is fever, battery life or user experience, it is gratifying. The slight disadvantage is that the screen will appear blue when it is tilted. Moreover, the camera performance is moderate, and it is slightly short-board when the hardware surface is generally excellent. For Xiaomi Note2, compared with the product, perhaps the stocking quantity is also the focus of everyone's concern. It is worth noting that the AMOLED flexible screen used in Xiaomi Note2 is manufactured by LG, which is the first time that LG has provided dual curved surface screen. It can be expected that there will be a shortage of supply in the early stage due to the climbing of screen production capacity. However, considering the product positioning, Xiaomi will try to increase production capacity throughout the product cycle.
