1. Foreword: The S series has passed the last hurdle of the all-around flagship
S series is the newest member of the Blue Factory family that was conceived by vivo in 2019. However, in the two years since its birth, as many as six have been launched. Each of these models has a distinctive personality-the S1, which focuses on "light-sensing selfie", sets the basic style; the "32 million lifting light-sensing selfie" S1 Pro seeks a breakthrough in appearance; "five super-textured beauty" The S5 has begun to penetrate into the subdivision field; the S6 and S7 have made thin and beautiful selfies to a height that is difficult to reach by conventional flagship models.
However, these five-generation models have always left room in terms of performance, and it is also the last hurdle that the vivo S series needs to overcome in order to become an all-around flagship.
Looking at the latest generation of vivo S9, it still continues to strengthen the lightness and beauty of the selfie, using ultra-night soft light dual-camera, of which the ultra-wide-angle lens is still 8 million pixels, supporting distortion correction, and the main camera is 44 million pixel AF The focus lens supports auto focus, and the amount of light has been increased by 12%.
In addition to improving the sensor of the front selfie lens, vivo also created the polar night micro-slit fill light for this machine. Two LED soft lights are added to the gap at the top of the screen to provide users in the polar night environment. The face provides uniform, three-dimensional light, and combined with the screen fill-in function since S6, it maximizes the brightness of low-light selfies, which is the reason for "illuminating my beauty".
Somewhat unexpectedly, the emergence of the new 6nm U-Dimensity 1100, allows the vivo S9 to make up for the previous trade-offs.
The following is our detailed evaluation experience of vivo S9 and Dimensity 1100.
2. Appearance: angular 173 grams of perfect figure
Compared with the previous generation, the screen size of the vivo S9 has not changed, and it also adopts a 6.44-inch 2400×1080 pixel resolution AMOLED full screen,Only the screen refresh rate and touch sampling rate have been upgraded to 90Hz and 180Hz respectively, and they have passed the TÜV Rheinland low blue light certification.
Because the “stacking” of the front main camera area is too dense, a 44-megapixel AF autofocus camera and an 8-megapixel 105° ultra-wide-angle lens can occupy a lot of space. In addition, to avoid The face is obviously deformed when taking selfies. Only when placed in the center can a better selfie effect be achieved. Therefore, the vivo S9 has the same design as the previous generation.
Chin details
The middle frame of the previous generation is still made of plastic, this generation is upgraded to use aluminum alloy metal, still adopting a straight-edge design, only in the middle frame and front and rear panels A circle of chamfering is added at the point of convergence. Since both the middle frame and the back panel adopt a flat design, they look sharp and angular.
The back design language of vivo S9 is closer to that of the previous generation, and it also uses cloud-level image modules. There has been a big change in color, multi-color gradation, and completely different light and color transformations appearing under different angles.
This phone is also vivo's thinnest 5G mobile phone so far-it adopts vivo's thinnest motherboard, the thinnest SIM card holder, the thinnest motherboard holder, the smallest shape photoelectric fingerprint, ultra-thin NFC coil , The highest cell system, the thinnest shielding cover, etc., can achieve the size of 158.39×73.87×7.35mm (Chaolubai, impression pickup is 158.39×73.87×7.43mm), and the weight is only 173g.

3. Selfie: main camera + ultra-wide-angle in place In addition, two soft lights are installed
Selfie has always been the highlight of the blue factory.The introduction and precipitation of “soft selfies” and “clear backlighting” to “AI” and “ultra-wide-angle” seem to be consciously and systematically promoting every project and technology related to selfies. Solve pain points for users.
The predecessor, the vivo S7, is already equipped with vivo’s highest-pixel selfie camera-the front 44MP ultra-high-definition PDAF autofocus main camera and 105° ultra-wide-angle sub-camera.
Vivo S9 not only increased the light input of the main camera by 12% compared to S7, but also pioneered the "front micro-slit fill light", making the concept of "extreme night soft light dual-camera" a reality.
It can be seen that the vivo S9 has added two soft lights in the gap at the top of the screen to fill in the self-portrait under low light. The hardware with the built-in light and the polar night selfie algorithm can let users Break through the shackles of night and maximize the brightness of night selfies.
It is worth mentioning that the emergence of this group of front micro-slit soft lights gives the vivo S9 more fresh ways to take selfies-the machine has launched a new "light and shadow" style, which contains " "Flash" (a bit like the flash effect of old-fashioned cameras), "Party", etc., which means that it introduces soft light into the filter to achieve a special light effect that can be regarded as an exclusive selfie.
The polar night portrait selfie algorithm of vivo S9 already has a background intelligent recognition function, which can partition the face and the background, which means that it will not affect the background noise and optimization. To the beauty effect on the human face.
IV. Rear image: 64 million pixel main camera leading the three-camera combination
For rear image, 64 million pixel main camera + 8 million pixel 120˚ super wide angle + 2 million pixel Macro three-shot solution,Can meet most shooting needs.

V. Performance test: 6nm new U! Dimensity 1100 debut show
vivo S9 is the first model of MediaTek's new 5G U-Dimensity 1100.
Dimensity 1100 uses TSMC's 6nm process technology, which follows the design rules of the 7nm process. TSMC's current 7nm process has two versions. The first generation 7nm (N7) uses traditional DUV lithography technology, and the second generation 7nm+ (N7+) is the first to join EUV extreme ultraviolet lithography.
6nm process also has EUV extreme ultraviolet lithography technology. Compared with 7nm+ (N7+), an extreme ultraviolet lithography layer is added. At the same time, compared with 7nm (N7), the transistor density can be increased by 18%, and the design rules are fully compatible with 7nm (N7) ), which is easy to upgrade and migrate and reduce costs. In contrast, 7nm+ (N7+) is another set of design rules.
CPU, Dimensity 1100 adopts 4+4 architecture, including 4 Cortex-A78 with main frequency of 2.6GHz and 4 Cortex-A55 with 2.0GHz.
GPU part, the Dimensity 1100 equipped in the vivo S9 integrates 9 Mali-G77 cores, compared with Dimensity 1000 Plus, there is no change.
We use PerfDog and Geekbench to collect the mobile phone's CPU and GPU power consumption data and calculate the CPU and GPU energy efficiency ratio. The specific method is as follows: the test model is set to the lowest brightness, and the same version of Geekbench is used.
First use Prefdog to test the power consumption, first turn off all backgrounds of the phone, with the lowest brightness, only turn on WiFi, and test the no-load power consumption of the phone at this time. The specific method is to select the phone desktop as the test software, and leave the phone to stand still. For any operation, obtain a power consumption curve and average power consumption value, and record the value.
then use Geekbench and GFXbench to run the scores, collect average power consumption data and subtract the no-load data during the running time to get the power consumption of the mobile phone processor. Combined with the test results, the frame rate, power consumption, and energy consumption ratio data calculated from this are finally obtained.
In order to feel the difference between the two more intuitively, our direct test results and energy efficiency ratio calculation results are summarized in the following table for reference.
VI. A series of tests for body temperature, storage, Antutu, and 5G
-body temperature
in the future , We will begin to introduce the temperature measurement link, specifically, the Antutu running test in a constant temperature indoor environment, using a temperature measuring gun to measure the highest temperature of the fuselage before and after the running.
The test was carried out in an environment with a room temperature of about 21°C.
The maximum temperature of the vivo S9 body was 28.4℃ before the running points, and it rose to 34℃ after the running points.
-store
before that,Whether it is the popular Dimensity 720 or the flagship Dimensity 1000+, the storage support can only reach UFS 2.2, which seems embarrassing among the flagship U at the time.
This generation of Dimensity 1100 has been upgraded in this respect, and has been able to support UFS 3.1 dual-channel flash memory, and the upper limit has been increased.

Considering that operators’ progress in 5G construction is much faster than expected. For example, some areas have begun to cover millimeter waves, and even NSA base stations have been shut down. It is conceivable that users’ demand for VoNR and dual carrier aggregation may not be satisfactory. distant.
As far as the backward compatibility of 5G networks is concerned, Dimensity 1100 has considerable advantages.
7. Charging life: 4000 mAh battery with 33W fast charge
vivo S9 is equipped with a 4000 mAh battery, supports 33W wired fast charge, and comes with the original charger.
Next, we will conduct a simple test of its battery life through online videos and mobile games.
I use the Bilibili client to play online barrage video with 30% volume and 75% brightness. According to the monitored current information, it can be estimated that the online video battery life of the vivo S9 under test conditions can reach about 12.6 hours.
The author is at 30% volume,Enter the "Peace Elite" training field at 75% brightness, turn on the limit frame rate, and according to the monitored current information, it can be estimated that the game life of the vivo S9 under test conditions can reach about 6 hours.
vivo S9 comes with a 33W charger. It takes 55 minutes to charge from 4% to 100%.
8. Summary: There is no problem in recreating explosive models
The perfect figure has always been a distinguishing feature of the vivo S series. Today, 5G mobile phones are "increasing weight and weight". The machine's body width is only 73.9mm, which is 0.3mm shorter than the S7; the body length is 158.39mm, which is 0.43mm less than the S7. Among them, the midnight blue version of the vivo S9 has a body thickness of only 7.35mm and a body weight of only 173g, making it the thinnest and lightest 5G mobile phone of vivo.
Each generation of S series mobile phones also emphasizes the innovation and challenges of mobile selfie solutions. The previous generation of vivo S7 already has the highest pixel selfie camera in the industry and the field of view reaches 105° super wide-angle sub-camera, to vivo The S9 generation has further emphasized the "extreme night soft light selfie." The specific implementation of
is not difficult to understand. It is the first "front micro-slit fill light" without taking up too much body space, which fully fills up portraits in low light in extreme environments. A filter with light effects was also introduced simultaneously to create a more atmospheric self-portrait gameplay for users.
In fact, when reviewing the two recent S series models-vivo S6 and vivo S7, we can find that this series of models has always had room for performance, whether it is the original Exynos 980 or the very polished The mature Snapdragon 765G is still some distance away from the performance flagship.
This time, the vivo S9, which debuted the Dimensity 1100, was obviously given by the Blue Factory to make up the last piece of wood in the bucket, and its performance far exceeds the previous generations of products.On the whole, the vivo S9 has crossed the last barrier to become an all-around flagship, becoming the strongest performance in the history of the S series, while also continuing to extend the S series's consistent advantages in appearance design and selfies.
Clarify user needs and build itself into a product that best meets the needs in the target price range. Together with comprehensive service capabilities, this is the feature of vivo S9. On this basis, the starting price of 2,999 yuan is more reasonable, combined with Lanchang's consistent strong position in the offline market, there is no problem in recreating explosive models.
