With the rapid development in recent years, the smart phone market, especially the domestic smart phone market, has become saturated, and the competition among manufacturers has become more intense, but at the same time, more problems have been exposed. With the rapid development, there is a serious homogenization of mobile phone products. Xiaomi mobile phone, which makes a lot of money with high cost performance, also faces the same problem. In the competition in recent years, it has gradually been overtaken by rivals, showing a slight decline, and the original market share has gradually been carved up and eroded. In this autumn new product launch conference, Xiaomi 5s and Xiaomi 5s Plus, two mobile phones brought by Xiaomi, are equipped with Snapdragon 82 1 processor. If divided by hardware performance, both are among the flagship. The starting price of Xiaomi 5s Plus is higher than Xiaomi 5s by 300 yuan, so it can be considered that its positioning is higher than Xiaomi 5s. However, at the press conference, Lei Jun spent a long time explaining and promoting Xiaomi 5s, while Xiaomi 5s Plus appeared less at the press conference and was taken away by Xiaomi 5s. Although it is also equipped with the latest Snapdragon 82 1 processor, Xiaomi 5s Plus is not equipped with the ultrasonic fingerprint recognition and 3D Touch that Xiaomi 5s has. In the naming relationship, they belong to the same generation of products in the same series, but it is difficult to see the corresponding relationship between the two mobile phones from the appearance. In terms of appearance, Xiaomi 5s Plus is more like a combination of Xiaomi Note and Red Rice Pro. In addition, the biggest difference between Xiaomi 5s Plus and Xiaomi 5s is that the former is equipped with color+black and white dual lenses, and the official publicity focus is on large-screen dual cameras. So what is the positioning of Xiaomi 5s Plus? For which user groups? We solve these problems through evaluation. At the beginning of the evaluation, let's first understand the hardware parameters of Xiaomi 5s Plus. Xiaomi 5s Plus uses a 5.7-inch 1080P screen, is equipped with Snapdragon 82 1 processor, and is equipped with 4+64GB/6+ 128GB of memory (our version is 6+ 128GB). Its biggest feature is the use of 6.5438+0.3 million pixel color+black and white dual lens. From the hardware configuration point of view, Xiaomi 5s Plus continues Xiaomi's consistent fever tradition, and the overall hardware performance is undoubtedly the top in the industry. Xiaomi 5s Plus is equipped with Qualcomm Snapdragon 82 1 processor, and Snapdragon 82 1 still uses Kryo, a self-developed architecture of 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 technological progress without power consumption problems. It can bring users shorter 10% startup time and faster application startup speed, and get smoother screen sliding operation and faster corresponding speed when the application starts, and get better practical experience. First, the appearance evaluation Xiaomi 5s Plus appeared at the press conference as the last product, and it didn't take too much time, which would make many users mistakenly think that this is an enlarged version of Xiaomi 5s, but it is not, whether in design or in specific functional configuration, Xiaomi 5s Plus still has many differences compared with Xiaomi 5s. Look at the appearance first. Xiaomi 5s no longer uses the slender Home button design at the bottom of Xiaomi 5 fuselage, and the new oval Home button is visually harmonious. At this point, Xiaomi 5s Plus is different from Xiaomi 5s. Xiaomi 5s Plus still adopts Xiaomi's consistent Android three-button design, which is less fresh. On the front of the fuselage, Xiaomi 5s Plius also uses 2.5D protective glass, which enhances the front impression and the grip on the edge of the fuselage. Large-screen mobile phones have always given people the impression that they are stupid, big, stupid and difficult to hold. The use of 2.5D glass can be said to be an essential design element of this mobile phone. Since the beginning of this year, all mobile phone manufacturers have taken symmetrical design as a major selling point of their products, making the whole machine look more concise. However, it is a pity that the layout of the top components of Xiaomi 5Plus fuselage did not follow the symmetrical design. In addition, Xiaomi 5s Plus does not place Xiaomi logo on the top of the front of the fuselage, which is also a major trend of Xiaomi mobile phone. Xiaomi 5s Plus offers three choices: gold, dark gray, silvery white and rose gold. The difference is that the first three are made of metal wire drawing process and finely polished, showing high-gloss texture (the same as red rice Pro), while rose gold is matte texture. It should be pointed out that Xiaomi 5s Plus does not adopt CNC machining commonly used in flagship mobile phones, but a three-stage design. Due to different materials, there is a certain color difference between the upper and lower ends and the middle metal part. Xiaomi 5s Plus put the fingerprint identification button on the back of the fuselage. Whether to put the fingerprint identification button in the front or in the back has always been controversial, but there is no question of who is more advanced. The reason why Xiaomi 5s Plus does this is because it is more convenient to use the fingerprint identification button on the back when holding a large-screen mobile phone. If it is designed at the bottom of the front of the fuselage, it will also increase the risk of falling. Xiaomi's Xiaomi Max, a large-screen mobile phone, also designed the fingerprint recognition button on the back of the fuselage. Headphone holes, noise-reducing Mic and infrared emitters are distributed on the top of the fuselage. In recent years, among the new mobile phones released by Xiaomi, infrared transmitters have increasingly become the standard of Xiaomi mobile phones. Built-in Xiaomi universal remote controller is very convenient to control household appliances such as air conditioner and TV, which is especially important for the layout of Xiaomi smart home products. At the bottom of the fuselage, Xiaomi 5s Plus adopts USB Type C interface. Compared with the traditional Micro USB interface, it can support greater data transmission speed and greater charging current. 20 16 has been fully popularized and is the quasi-successor of Micro USB interface. There are also two injection molding strips at the bottom of the fuselage, and the stacking of too many elements makes the bottom of the fuselage slightly messy. The above is the appearance analysis of Xiaomi 5s Plus. Xiaomi 5Plus, Xiaomi 5 and Xiaomi 5s did not show any inheritance in id design, but borrowed some design elements from Xiaomi Note and Red Rice Pro, which seemed to be a combination of the two. Compared with competing products, the three-stage fuselage of Xiaomi 5s Plus is also slightly lacking in sincerity, just like the simple stacking of existing technologies and processes. It's enough to say so. Second, the system evaluation system software part, Xiaomi 5s Plus factory pre-installed MIUI 8 system. As a representative of the old Android UI in China, MIUI 8 has been further optimized in terms of function and performance. At the time of this conference, MIUI 8 did not usher in a major update. In the part of system software, we mainly introduce the characteristics and highlights of the system. Compared with the previous version, MIUI 8 redesigned the UI interface of the system. For example, the notice bar can automatically change color according to the weather. The setup menu is changed to the original card style, the multi-task menu is embedded in the music player plug-in, and the Xiaomi notes, tape recorders, calculators and other applications are redone. In addition, MIUI 8 has added a screen-locked pictorial function, which can automatically change the screen-locked wallpaper according to the user's preferences, and every time the screen is lit, it is a different mood. In the details of UI, MIUI 8 has added many dynamic effects, which are used in calendars, tape recorders, weather and other software. At the same time, MIUI 8 also adopted Xiaomi Lanting font, and optimized the details of the standard Lanting font, which enhanced the unity between words and improved the reading experience. Featured functions. Various rich and practical functions have always been a major feature of MIUI. MIUI 8 has added functions such as mobile phone avatar, application avatar, long screen capture and floating ball. , and deeply optimized the calculator, scanning and gallery. Basically, there are many popular new features, MIUI 8. Let's introduce several major features below. In essence, a mobile phone can have two systems at the same time, so that the two systems can be used separately as private spaces. When this function is enabled, a system with two avatars will generate three new functions on the desktop, namely data migration, avatar setting and avatar switching. In other words, you can migrate applications, photos, files, total records and other materials of the original system, without repeatedly installing applications or copying files, and without occupying additional storage space. In addition, users can also set different screen lock passwords and choose to enter the original system or avatar system. Business people often use two mobile phones to separate their life and work, but it is really inconvenient to carry two mobile phones with them. MIUI 8' s mobile phone avatar function is a good solution for this kind of business people. In MIUI 8, the ordinary calculator was upgraded to a full-function calculator, and only Xiaomi mobile phone can calmly deal with the complicated calculation problems in life. The initial calculation interface of the calculator is the same as before, but click the button in the upper left corner of the page and you will find that the calculator integrates practical tools such as calculating mortgage, individual tax, provident fund and unit conversion, and is suitable for various calculation scenarios. For example, the girls' market in Aihaitao will pay attention to Japanese and Korean cosmetics. In the face of unfamiliar currency units, the price of goods can not be reflected in time, and how much money is saved is also at a loss. With Xiaomi's calculator, the exchange rate conversion is fast and supports multiple currencies. The exchange rate is also updated in time, so that Haitao will never be 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. As the most basic application of MIUI, photo album directly affects the user experience, so it has also been carefully built on MIUI 8. In the presentation of photos, panorama, continuous shooting map and GIF animation all have personality icons. When selecting pictures, the brand-new photo album supports sliding selection, and the number of selected photos will be displayed with the selection, which is convenient for users to further manage. It is worth mentioning that the new photo album has added slimming function, that is, the mobile phone keeps and displays thumbnails with a certain resolution to ensure daily browsing and social sharing, while high-quality original pictures are saved in the cloud and can be downloaded online when necessary. After verification, this mode can save 90% storage space, which is of great practical significance for friends with tight memory. In addition, the function of long screen capture is believed to be familiar to everyone, and MIUI 8 also supports long screen capture. Different from the screen capture function of other UIs, the long screen capture of MIUI 8 can be adjusted by sliding by hand during the screen capture process, which is more convenient and practical. Although MIUI is not the first system UI to take long screen shots, it is basically the best to use. There are also many application scenarios of this function, such as intercepting web pages and intercepting chat records of social software (WeChat, QQ, etc.). ) is used to share chat content. Basically, all pages that can slide down can use the long screen capture function, and there is no need to piece together a few screenshots. Performance and security optimization. In MIUI 8' s power saving mode, the system will control background activities, stop synchronization and weaken some visual effects. Officials say it can be used for 2 hours longer than the normal mode. In terms of security, MIUI 8 has joined the chain startup management, which can effectively limit the problem of chain wake-up in the background of a single application. In addition, it is worth mentioning that MIUI 8 system has added the chip-level pseudo base station short message identification function, and through the combination of pseudo base station short message identification, short message phishing website risk warning and browser URL detection, users are completely prevented from being deceived by pseudo base station short messages. Nowadays, the concealment of pseudo base station SMS fraud is getting higher and higher, especially for the elderly. MIUI 8' s pseudo base station SMS identification function reduces the risk of user property loss through various reminders. Another most noteworthy function is Xiaomi's payment. Earlier this month, Xiaomi and China UnionPay officially released Xiaomi Pay, becoming the first mobile phone manufacturer in China to reach a cooperation with UnionPay after Apple and Samsung. Xiaomi Payment supports both bank cards and bus cards. You don't even have to bring your wallet when you go out in the future. Bank cards and bus cards are fixed. Xiaomi paid the first batch of cooperative banks as many as 20, covering major domestic banks. Xiaomi 5Plus has a full-featured NFC chip, which supports card reading, card writing, analog card and P2P mode. As one of the earliest customized Android UIs in China, MIUI's rich and practical functions have always been a major advantage of MIUI. MIUI 8 can be said to be a milestone upgrade. Whether it is the optimization of system-level applications such as photo albums and calculators, or new functions such as system avatars and long screenshots, the experience is very good. In the case that the UIs of major mobile phone manufacturers are slowly catching up, MIUI still has the strength and advantages that cannot be underestimated, and it is still the leader of domestic Android UIs. Third, photo evaluation Obviously, there are more and more mobile phones equipped with dual cameras this year. At present, there are two widely used schemes, one is represented by HTC One M8, the other is responsible for recording image information, and the other is responsible for recording depth of field information, with the main purpose of highlighting the depth of field effect; One, represented by Huawei P9, adopts color+black and white cameras, one is responsible for shooting the color of the object and the other is responsible for recording the black and white information. The main purpose is to improve the image quality. The scheme chosen by Xiaomi 5s Plus is the latter. The reason why this can improve the imaging performance is that in the imaging process of traditional sensors, when light passes through the filter, no pixel produces a color value, and the information of missing color must be calculated by using the difference between adjacent pixels. Because there is no filter, the black-and-white lens takes more light when taking pictures than the traditional camera, so it can improve the dynamic range of the picture and reduce the noise when imaging. When taking a photo, two photos are combined into one, which can keep more details and have no influence on the color. At the same time, it is also helpful to improve the imaging performance in dark environment. After a brief analysis of the imaging principle of Xiaomi 5s Plus, we will look at the imaging performance of this mobile phone through the actual proofs. (The comparison model is iPhone 7 Plus). ▲ Xiaomi 5s Plus indoor lighting sample ▲iPhone 7 Plus indoor lighting sample In the indoor lighting environment, we can find that the ISO value of Xiaomi 5s Plus is only 40, which is much lower than that of iPhone 7 Plus. Under such conditions, the screen brightness of Xiaomi 5s Plus is significantly higher than that of iPhone 7 Plus, and the dual cameras have obvious advantages in large light input. Due to the smaller ISO, Xiaomi 5s Plus is slightly better than iPhone 7 Plus in picture purity. ▲ Xiaomi 5s Plus indoor lighting environment sample ▲iPhone 7 Plus indoor lighting environment sample Let's look at a set of comparative samples of indoor lighting environment. At the beginning of this section, we mentioned that the imaging principle of Xiaomi 5Plus is to synthesize the information of two cameras, which should be able to keep more details in theory. However, by enlarging the unified details to 100%, it is found that the details of Xiaomi 5s Plus are not as good as those of iPhone 7 Plus, and the edges are blurred. I guess this should be the problem of synthesis algorithm, and Xiaomi's control of this dual-lens scheme is not mature. ▲ Xiaomi 5s Plus outdoor night defense ▲iPhone 7 Plus outdoor night defense outdoor night defense, focusing on several luminous fonts of "Beijing Bayi Middle School". The picture brightness of Xiaomi 5s Plus is slightly brighter, but through the comparison of details, it is found that the font edge of Xiaomi 5s Plus is blurred and the smear feeling is serious. The exposure control performance of the light source (light box) appearing in the contrast screen is not as good as that of the iPhone 7 Plus. Due to time, this comparison only selects the imaging performance of two mobile phones at night and in dark environment for comparison (the daytime proofs will be compared later). Xiaomi 5s Plus takes advantage of dual cameras, and the picture brightness is higher in most environments. However, it is also obvious that the control ability of dual lens is insufficient, and the algorithm optimization is still not completed. In terms of detail expression and exposure control, Xiaomi 5s Plus was completely defeated compared with iPhone 7 Plus. On the other hand, considering that mobile phone photos are mostly used in social channels, the overall impression of photos is more important. The imaging performance of Xiaomi 5s Plus can cope with the spread of social applications such as Weibo and WeChat, and it still shows certain advantages compared with iPhone 7 Plus in image perception. Fourth, in terms of performance evaluation hardware, Xiaomi 5s Plus adopts 5.7-inch 1080P full HD screen, equipped with Qualcomm Snapdragon 82 1 quad-core processor, and 4GB/6GB and 64GB/ 128GB storage space. If we look at the configuration of Xiaomi 5s Plus in this way, we can see that the performance is much more conscience than Xiaomi 5, but this price is more conscience. For Qualcomm Snapdragon 82 1 and 4GB memory, it can basically meet the needs of most users. It is worth mentioning that the Qualcomm Snapdragon 82 1 processor used in Xiaomi 5s Plus is a high-frequency version with a main frequency of 2.35GHz, and the low-frequency version is 2. 15GHz. Snapdragon 82 1 still adopts the Kryo architecture independently 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 increase its running speed without power consumption problems through technological progress. It can bring users shorter 10% startup time and faster application startup speed, and get smoother screen sliding operation and faster corresponding speed when the application starts, and get better practical experience. Compared with the leap from 8 10 to 820, Snapdragon 82 1 mainly focuses on releasing new functions, optimizing performance and improving existing functions. So the main performance is not much different from the Xiaolong 820 that we are familiar with this year. So in the hardware performance part, we won't analyze the processor in detail. Mainly through running score data, let everyone have an intuitive impression on the performance of this mobile phone. In Ann Bunny's running test, Xiaomi 5Plus finally scored 137895. Before the press conference, it was reported that the highest score of the aircraft could reach 160000 or above. Running will fluctuate due to ambient temperature and system usage, so you don't need to care too much about running. Understandably, Snapdragon 82 1 processor is the best mobile processor in the Android camp at present. Evaluation summary: On the whole, Xiaomi 5s Plus equipped with Snapdragon 82 1 processor has the top hardware performance at present, with a high cost performance at the price of 2299 yuan, and it is still a Xiaomi mobile phone that is close to the people. The black-and-white+color dual lens used by Xiaomi for the first time also adds a certain playability to the photo experience, and the picture quality is remarkable. The rich and easy-to-use MIUI 8 system still dominates the Android camp, which is really a big plus for this machine. However, in terms of appearance, although Xiaomi 5s Plus adopts metal wire drawing process and has been polished by multiple processes, the overall texture of the three-stage fuselage design is far less intense than that of the CNC integrated fuselage, which is a simple superposition of existing technologies and processes. Not only the fuselage technology, but also the overall ID design of Xiaomi 5s Plus draws on Xiaomi Note and Red Rice Pro, which lacks bright spots and innovation in appearance. In addition, the black-and-white+color dual lens equipped with Xiaomi 5s Plus improves the imaging performance of the camera to a certain extent, but in the actual experience, it also reveals that Xiaomi's ability to control the dual lens is insufficient, and there is still a lack of software algorithm optimization. There is a certain gap between the overall imaging level and the top camera phones. If you are going to buy this phone for dual lens, you really need to think carefully. But as far as the cost performance of the whole machine is concerned, Xiaomi 5s Plus is still worth buying.
