IT168 evaluation Since 2015, ZTE has gradually taken the road of high-quality products. Launched the high-end flagship Tianji series, and established the ZTE young fashion boutique series and the Blade national popular high-quality product series. The three product lines form ZTE's new product pyramid, and the product focus gradually moves upward, focusing more on the mid-to-high-end market. When it comes to the Tianji series, it has always been the high-end flagship product of the family, so today ZTE Tianji 7 assumes the important role of the family flagship.

"Tianji 7" is the seventh generation product of ZTE's Tianji series. Starting from the GRAND S released in January 2013, which is the first generation of Tianji, the Tianji series has continued to iterate and evolve, with independent design language and High-quality experience has accumulated a good reputation among users. In 2015, Tianji adopted the name "Tianji", marking the beginning of a milestone for ZTE to officially enter the high-end market. "Tianji 7", the return of the naming sequence can also be regarded as an insistence on the quality of the Tianji series.

Since ZTE Terminal announced its strategy of creating high-quality products in 2015, products have been named after the parent brand ZTE series. All Tianji series products are also the second batch of named products. The financial report for the first quarter of 2016 showed that ZTE achieved revenue of 21.859 billion yuan in the first quarter, a year-on-year increase of 4.09%; net profit was 950 million yuan, a year-on-year increase of 15.97%; basic earnings per share was 0.23 yuan. At the beginning of the year, Yu Yifang, Vice President of ZTE and Executive Vice President of Terminal China, said that 2016 was full of expectations and expectations, and he hoped that the overall sales volume could double in 2016. So how can we double sales? The most conventional and direct method we see now is to improve the overall configuration and highlight the buying points of the product.

Tianji 7 is equipped with a 5.5-inch AMOLED 2K Super Retina Magic Screen and AK4961+AK4490 dual flagship independent audio processing chips. The ultimate configuration brings A cinema-like audio-visual feast; the system-level voice control solution allows you to follow the "sound" and enjoy an efficient and convenient mobile life. Its ID design language combines the characteristics of "high quality", "uniqueness" and "experience". The performance is very direct. In addition, ZTE signed Lang Lang as the image spokesperson of the Tianji series, which completely replicates the successful case in the United States. It can be said to accelerate the brand promotion strategy in the transformation and upgrading.

In terms of appearance, Compared with the previous generation, the overall design style of ZTE Tianji 7 has not changed much. It still has a design of 2.5D glass on the front and a three-section metal body on the back. It has a calm and restrained business style. However, in the details of the fuselage, ZTE Tianji actually has a unique design. 7 has added some interesting small changes to improve the practicality and grip of the whole phone. Let’s take a closer look at the appearance design of this phone.

On the front of the phone, ZTE Tianji 7 is practical. It has a dual-speaker design, which is rare among mainstream mobile phones today. The design of 2.5D glass is not only a major plus point for the appearance of the whole machine, but also improves the gripping feel on the edge of the fuselage. The larger front part of the fuselage is the speaker openings at the upper and lower ends. This time ZTE Tianji 7 has canceled the previous diamond mesh design and adopted the current round punching hole. It looks much more restrained and low-key under the wooden decoration of the high-end version. , showy but not ostentatious. In human terms, ZTE Tianji 7 is like a mature and stable business man.

In 2015, the USB Type-C interface standard was tested on mobile phones, and it has become very popular in 2016. Currently, even many thousand-dollar models are equipped with Type-C interfaces. The speaker of ZTE Tianji 7 is located on the front of the fuselage, so the bottom of the fuselage only has data and microphone openings, so the bottom is very simple and integrated.

On the back of the fuselage, ZTE Tianji 7 adopts a three-section metal body design. Although the design of metal body + injection molding strip is not new, in fact this design requires relatively high process difficulty. The seams and tolerances between plastic and metal are all direct factors that affect the yield, so the cost is also relatively high. Higher, often used on flagship models. After hands-on experience, there is no obvious friction between the injection molded strip and the metal body of the machine, and the overall workmanship is satisfactory.

It is worth mentioning on the back of the fuselage that ZTE Tianji 7 has added groove processing to the fingerprint recognition button. The official explanation of this design is that this makes it easier for fingers to identify the location of the fingerprint button and operate it. More convenient. In addition, ZTE Tianji 7 uses a 20-megapixel camera on the back. There is a metal ring around the lens for protection, reducing the risk of the lens being scratched.

The screen size of ZTE Tianji 7 is 5.5 inches, which belongs to the category of large-screen mobile phones. However, thanks to the higher screen-to-body ratio, the body size of ZTE Tianji 7 is relatively well controlled. Coupled with the smooth transition of the edges of the fuselage, these give ZTE Tianji 7 a better grip feel. In some cases (such as replying to text messages), one-handed operation does not seem very cramped.

"Summary

: In terms of appearance, ZTE Tianji 7 continues the design style of the previous generation, and the overall appearance has not changed significantly. But it also follows the current mainstream design of high screen-to-body ratio Trend, combined with 2.5D glass, has a good front look. Especially the walnut decoration used in the top version has become the finishing touch of this phone, which is a major differentiation highlight and a manifestation of identity. Simple summary, full of personality and calm and restrained.

In terms of system UI, ZTE Tianji 7 runs MiFavor UI 4.0 version based on Android 6.0.1, compared with the more mature domestic MIUI and Flyme. , MiFavor UI does not seem to be particularly famous, but in fact, when comparing the system UIs of various companies, it is difficult to find some obvious deficiencies and shortcomings, whether in terms of performance, interaction or functionality. The gap is very small. Let’s give a brief explanation of MiFavor UI 4.0, mainly to look at its performance in terms of interface aesthetics and functional practicality.

In terms of the overall style of the interface, MiFavor UI 4.0 is an iOS-like style that is more common in domestic Android systems. The icons are also rounded rectangles, which is relatively traditional. It is not as bold and radical as Smartisan OS and Hydrogen OS. The color scheme of the interface is low-key and restrained, which is different from ZTE Tianji 7's toughness and stability. It echoes the business style and achieves both internal and external improvements.

Although Mifavor UI 4.0 takes an iOS-like route as a whole, and the system interface has been deeply optimized, there are still some problems in the drop-down menu and volume adjustment window. It has a strong flavor of native Android. Both the arrangement and style of the icons are almost the same as the native Android interface.

MiFavor UI 4.0 introduces the new Smart Voice 3.0, which is a major feature of ZTE mobile phones. , the previous Star series mobile phones focused on the voice function. Smart Voice 3.0 has been fully upgraded. The voice secretary supports online voice-to-text and offline voice-to-text, which is simply amazing for handling usage scenarios such as meeting records and memos. After a simple test, the recognition success rate of Voice Secretary is very high. Surprisingly, its recognition speed is even faster. This should be because of the use of offline voice packages. Similarly, the voice translation function supports conversation and text. Converted into 9 foreign languages ??including English, Cantonese, Japanese, Spanish, and Korean, it is an out-and-out travel companion.

In the phone application, MiFavor UI 4.0 also integrates the daily yellow pages function. All kinds of information about food, hotels, banks, leisure and entertainment are all available, which is very convenient. At the same time, the dial also supports pinyin search. If you need to find the SF express phone number, just press the pinyin and type "shunfeng" to quickly find the SF Express phone number. Service phone number. At present, more and more domestic Android UIs are also improving and enriching localization functions. This is also a major advantage of domestic UIs compared with international manufacturers such as Samsung and Sony in terms of system UI.

"Summary

: After several major version changes, MiFavor UI has become increasingly mature and perfect, and its functionality has basically caught up with excellent domestic UIs such as MIUI and Flyme. Especially in terms of voice functions, the newly upgraded Smart Voice 3.0 has reached a new level in terms of recognition speed and accuracy, and has very high practicality. However, in terms of interface interaction and system aesthetics, MiFavor has reached a new level. It seems that it has not fully formed its own unique style and lacks characteristics.

"Dual independent operational amplifier chips

It is worth mentioning that this time ZTE Tianji 7 is equipped with the AK4961 chip used in Sony's professional recording pens, and is used with iRiver's AK380 professional HiFi player The AK4490 chip and dual flagship independent audio processing chips ensure this phone's high-fidelity recording and playback and full-range pure sound experience. Three-way echo cancellation allows Tianji 7 to achieve high-definition recording within a distance of 8 meters, 360-degree automatic sound source identification and ultimate noise reduction. , allowing users to maximize the experience of a professional portable recording studio.

ZTE Tianji 7 is also equipped with dual speakers + dual Smart Pa. This is also the first mobile phone to use a dual speaker design. Dolby panoramic sound effects, coupled with professional "golden ear" tuning, allow users to have the most surround-sound high-definition sound experience on current smartphones. In the actual listening experience, ZTE Tianji 7's music playback effect is amazing. I was impressed by the deep speakers. When the environment is quiet, the sense of immersive presence can even be compared to the iMax theater.

Tianji 7 uses a front-facing 8-megapixel camera and a rear 20-megapixel camera. The pixel camera is equipped with "ball bearing optical anti-shake + electronic anti-shake + image compensation" super hybrid anti-shake, which greatly improves shooting stability. In addition, it also has multiple exposures, time-lapse photography, time slowdown, slow motion, 360-degree panorama, etc. and a series of functions. Thanks to user big data research, automatic recognition of professional scenes, automatic optimization and adaptation of parameters, professional photography teaching, etc., Tianji 7 can achieve a photography experience of taking high-quality photos easily in automatic mode.

Since it is a flagship phone, we also need to compare it with the current camera benchmark iPhone 6s Plus in terms of photography. Although Apple is the camera benchmark, with the development of Android phones, it has also made rapid progress in photography. When evaluating whether a mobile phone takes good photos, our first reaction is whether the color is closer to what we see with the naked eye. In the first set of comparison samples, we can see that the white balance of the Apple iPhone 6s Plus is already comparable to that of the Android flagship Tianji 7. There is a certain gap. The white balance of Tianji 7 is more accurate, and the overall picture is brighter, while Apple's Tianji 7 uses a 2-megapixel camera. In the test, we can also see that there is a certain gap between the two 100% samples. The Tianji 7 can still see most of the crystal cutting angle, while the Apple iPhone 6s Plus is mostly in a heavily smeared state. This is due to the Tianji. 7's 20-megapixel camera.

The Tianji 7's rear 20-megapixel camera is equipped with "ball bearing optical image stabilization + electronic image stabilization" super hybrid image stabilization, which greatly improves shooting stability. I also deliberately took photos of night scenes on the move, and the overall performance was quite satisfactory. We can see that the coffee shop logo, graphics, and text are all quite clear in the snapshot list, especially the large logo with sharp corners. In addition, we can also see that the black part of the screen is very pure throughout the day, and there will be no screen blur.

▲Multiple Exposure (1)

Multiple Exposure (2)

Tongtianji 7 also continues to have fun cameras The fine tradition of the ZTE family has a series of functions such as multiple exposure, time-lapse photography, time shutter, slow motion, 360-degree panorama, etc. We can take more interesting photos through the combination of these. For example, in the first group, we used the simplest multiple exposure, shooting the tabletop first and then the drink bottle, so that we can see the virtual drink bottle placed on the tabletop. The second photo uses a more difficult multiple exposure, and the combination of the two photos can spoof the drink bottle.

Through the experience of the camera, we can definitely think that Tianji 7 has maintained the family's consistent high level in taking pictures, and also added multi-functional photography on the original basis. Mode allows us to customize more intentional photos. Indeed, when mobile phone photography is generally good, the speed, accuracy, stability and playability of the camera itself are very important.

"Interpretation of Snapdragon 820 Processor

"

This time ZTE Tianji 7 is equipped with Qualcomm Snapdragon 820 platform. This is also the year of 2016. Standard configuration for flagship phones. When it comes to the performance of the Snapdragon 820, we must first mention the Samsung 14nm FinFET process selected for the Snapdragon 820. Simply put, more advanced processes can increase the number of transistors per unit area, improve transistor performance, and improve overall chip performance. At the same time, more advanced manufacturing processes can also achieve the effect of reducing leakage rate, reducing power consumption and reducing heat generation. Generally speaking, more advanced processes can achieve higher performance under the same power consumption, and have better power consumption performance under the same performance.

In the author’s impression, Qualcomm has several influential SoC products: QSD8250, QSD8260, APQ8064, Snapdragon 800, Snapdragon 801, Snapdragon 820, etc.

Among them, QSD8250/8260 uses the self-developed Scorpion architecture, Snapdragon 800/801 uses the self-developed Krait architecture, and this time the Snapdragon 820 uses the latest Kryo self-developed architecture.

The Snapdragon 820, which uses the Kryo architecture this time, adopts a quad-core design with a clock frequency of 2.15GHz. However, there is one thing worthy of our attention. Compared with APQ8064, Snapdragon 800, and Snapdragon 801, this time Snapdragon 820 uses a four-core design of 2*2.2GHz+2*1.5GHz with different clock frequencies. At the same time, the previous Snapdragon 800 used 4aSMP, which is four asynchronous symmetrical cores. Each core can be controlled independently, and there is no difference in the frequency of each core. This time, the Snapdragon 820 uses two clusters of core management and control 2aSMP, which is a 2+2 asynchronous symmetrical core. In other words, the two 1.5GHz cores are synchronous and the same frequency, and the two 2.15GHz cores are also synchronous and the same frequency, but An asynchronous symmetrical design is adopted between these two clusters of core groups. At this point, you may think that the Snapdragon 820 also adopts a design similar to big.LITTLE, but according to Qualcomm’s official explanation, this is not the case. The two cluster core groups only differ in clock frequency, but still use the same Kryo architecture. .

Note: The data in the above picture comes from AnTuTu official website. The running scores in the data come from Samsung Galaxy S7 China version (Qualcomm Snapdragon 820),

), Samsung Galaxy S7 Korean version (Exynos 8890), Meizu Pro 6 (MediaTek Helio X25), Huawei P9 Plus (Hisilicon Kirin 955).

▲ZTE AXON 7 AnTuTu score

Through the above comparison, we can see that the overall performance of Qualcomm Snapdragon 820 is beyond doubt, and it is worthy of being the flagship SOC in 2016. Compared with the Samsung S7 China version in the above data, the top-end version of ZTE AXON 7 is equipped with a larger 6GB memory. We are also looking forward to the running scores of this machine. After receiving the machine, we couldn’t wait to test it with AnTuTu. It lived up to expectations. ZTE AXON 7 scored a high score of 133791, ranking among the top in the current AnTuTu benchmark library, which is a pretty good result.

Qualcomm (Qualcomm)

Official website

Qualcomm official data shows that compared to the previous generation Adreno, the Adreno 530 The performance of the 430 is increased by 40%, and the power consumption is reduced by 40%, all thanks to the new architecture design of the Adreno 530. Qualcomm engineers also specifically mentioned that there is an ultra-low-power processor embedded inside the Adreno 530, which is used to detect GPU power consumption and dynamically adjust the GPU to keep it in optimal condition. The highest frequency of the Adreno 530 is 650MHz. And on Adreno 530, Qualcomm took the lead in supporting the latest OpenCL 2.0 and Renderscript. This is also the first smartphone SoC to support OpenCL 2.0. Previously, only high-end desktop graphics cards such as Nvidia Titan supported this specification, which also helps game design manufacturers to more easily port their PC masterpieces to smartphones/tablets.

As for performance, we also conducted a GPU display performance test through GFXbench. Through comparison, we can see that compared with 15-year-old flagship GPUs such as Adreno 430 and Mali-T760, there is still a big improvement, and it is basically on the same level as the PowerVR 7XT series GPUs on iPhone6s/6s Plus. Generally speaking, the GPU we understand only handles UI sliding, rendering game scenes, and assisting the CPU in calculations. But in the future, aspects including 4K video, virtual reality display, augmented reality display, etc. will also play a decisive role.

As the flagship product of ZTE Mobile in 2016, Tianji 7 has been fully upgraded from the inside out. Zeng Xuezhong, executive vice president and terminal CEO of ZTE, said, “In addition to the compatibility with international temperament, the core features of the product are also important considerations. , when Tianji 7, which has undergone rigorous polishing of sound effects, meets Lang Lang, a piano master who is dedicated to music, the ultimate high-definition audio-visual experience becomes a common pursuit. Tianji 7 will become the new favorite and favorite of new business people, providing both The three-dimensional immersive sound field enjoyment can also meet the needs of listening to high-quality music. "Indeed, in the era of serious homogenization of domestic mobile phones, Tianji 7 focuses on music and debugs it from the software and hardware, which is indeed very attractive. Simply put, if you want to buy a high-end HiFi mobile phone, Tianji 7 is a good choice.

Since 2015, ZTE has made significant efforts in brand building, adhering to localized sports marketing strategies, and through cooperation with basketball, football and other fields, which has greatly enhanced ZTE’s global visibility and brand. The image is on the upward track.

This time in China, ZTE launched its first spokesperson program during the high-end transformation period, signing Lang Lang as the spokesperson for the Tianji flagship series, which can be said to accelerate the brand promotion strategy during the transformation and upgrading.

Tianji 7 provides three versions: standard version (4+64GB), high-end version (4+128GB), and top-end version (6+128GB), priced at 2899, 3299 and 4099 yuan respectively. . The body color is available in two colors: Walkin and Stan Gray. Both versions can be reserved on JD.com starting from May 26, and will be officially launched on June 2. The high-end version will also be sold simultaneously through offline channels in major cities in various provinces.
