Less than 8 months after the release of the previous generation of X6, vivo released vivo X7 on June 30. This is one of the few products that Vivo uses the number "7" as its code name=[=[[product. The new machine is equipped with this year's famous U Snapdragon 652, which has upgraded its battery to 3000mAh. It is equipped with a 16 million pixel front camera, has switched to the front fingerprint identification scheme and redesigned the entire front. What will happen to the X7 after the major change? Let's take a look now.
This evaluation mainly focuses on its appearance, performance, system and front fingerprint identification scheme, photography and endurance.

Vivo X6/X6 Plus and X7/X7 Plus Parameter Comparison Table
Appearance and workmanship
The vivo X7 is packed in a pure white paper box. The first layer of the package is the machine, and the lower layer is very rich in accessories, including two water jackets and films of different colors in addition to the flash charger, data cable, card pick-up pin and headset. In addition, when the machine leaves the factory, it has already been pasted with a film, so you don't need to buy other parts after you buy it.
The charger supports 5V2A and 9V2A output, with a nominal maximum power of 18W. The size and weight of the charger are larger than those of conventional manufacturers such as Xiaomi/Meizu.
The front of the new machine is a very popular rounded rectangle+oval Home key design this year. Although it has some black edges, the overall frame is relatively narrow, which is very pleasing to the eye, but it is also true It's easy to bump into your face.
On the top are 16 million pixel front camera, earpiece, light/distance sensor, and Moonlight front soft light, which is the focus of this promotion.
At the bottom is the Home key that supports fingerprint recognition, and on both sides are the menu key with backlight and the return key.
The back is a vivo family style design, with an all metal integrated body, two antenna separation strips at the top and bottom, and a circle of polished chamfers around.
The top is the camera and flash, and the bottom is a simple body information.
The volume and power keys are on the right, and the sim card slot is on the left. It supports two nano SIM cards but does not support TF card expansion. It can be seen from the side that the edge of the machine is more rounded, and the 2.5D glass arc on the front extends all the way to the screen, with a ring of high plastic washer on the screen edge.
At the bottom of the body are earphone interface, microphone, mirco USB interface and speaker. There are many openings, but at least they are on a horizontal line.
Workmanship&feel&fingerprint identification
The workmanship of the machine is still familiar to Vivo: the keys are small and spring back easily when pressed; The all metal integrated sim card is slightly lower than the fuselage, and the combination is compact without any vacancy; The front Home button is slightly lower than the screen, and the zirconium gem cover plate and other parts are more white. The press feel feedback is solid, there is no snap sound, and the back bright edge even has its own radian. The workmanship is perfect.
The key word that runs through the appearance of the whole new machine is "round". The frame with a larger radian, a more obvious corner on the back, many gaskets and 2.5D glass that are higher than the metal frame, make the machine very close to the palm of the hand. The 5.2 inch screen and narrow frame bring excellent one hand operability, and the feeling is summarized as "cool".
The previous generation of vivo X6 has a record breaking speed of back fingerprint recognition, while this year's X7 has changed to a front fingerprint recognition scheme, but the unlocking speed is still very fast. When the screen is lit, the unlocking can be completed at the moment of contact; Under the status of resting screen, the speed is "slightly slower" than that when the screen is lit, but the whole process is less than half a second, and the machine can still complete the unlocking when it is quickly stopped after touching.
The unlocking speed is far more shocking than the nominal 0.15/0.2 seconds. It is almost impossible for daily users to feel the existence of fingerprint locks. Now only OPPO R9 can match its speed. In addition, it can be unlocked by tapping the home key or pressing it directly. It is more convenient to use without pressing the power key for daily use.
screen
The vivo X7 has a 5.2 inch Super AMOLED display, but There is no mechanism for brightness explosion under strong light. The highest brightness in the center of the test we got is 343 nits. Reducing the display area can increase the local brightness to 400 nits.
The brightness of the upper part of the screen is about 380 nits, and that of the lower part is about 330 nits. The backlight uniformity is average. Visually, the color temperature of this AMOLED screen is cold, and the hair color is rich and colorful, which is more pleasing to the eye, but the color is accurate and standard.
system
The vivo X7 is equipped with Android 5.1 based Funtouch OS 2.5.1, and the new system has not changed much. The typical features of Fontouch OS are a single-layer desktop, an icon that mimics the flat wind of objects, a pull-up bar that integrates the multi task manager, a simple setting menu, and rich body feel operations and advanced functions. The detailed design and function settings can be viewed from the previous system evaluation, which will not be repeated here.
The optimization of Funtouch OS has always been good. Many low performance machines can run smoothly before. The X7 equipped with Snapdragon 652 has no reason to get stuck. Whether the machine moves or responds quickly, the GPU curve is far more than the smooth line of 60 frames, and the actual experience is very smooth.
The main changes of the new system on X7 are the global eye protection function and the optimization of the entity home key. The former will filter the blue light after it is turned on, and the direct effect is that the whole screen is yellow. The latter can add the function of double clicking the home key to quickly start the camera, flashlight, WeChat and QQ.
The previous multi task split screen function has also been strengthened. In some applications, the three finger slide can trigger split screen. But it is mainly limited to reading and video applications. The picture scale can be dragged by yourself, and horizontal evaluation is supported. Drag and drop one side of the full screen, and the other app will be displayed as a hover icon.
In addition, the touch button of X7 is triggered only when the hand is released. To achieve high response, the hand must be released quickly, which is different from many machines. The home key is triggered to return to the home page by tapping or pressing. Users who have used traditional Android phones or iPhones can quickly adapt, but it may take some time for users who have used Meizu or Zuk phones before to adapt.
performance
CPU computing performance
GPU graphics performance
Flash memory read/write performance
The vivo X7 is equipped with Qualcomm Snapdragon 652+4G LPDDR3 memory+64GB storage. The CPU of Snapdragon 652 consists of four 1.8G A72 and four 1.4G A53. The GPU is Adreno 510@624MHz 。 Snapdragon 652 It is one of the biggest dark horses in the SoC market this year. It has appeared on X6S Plus, Xplay5 standard version, Xiaomi Max and other models. I believe everyone is familiar with its performance. The CPU computing performance of Snapdragon 652 surpasses that of the previous generation flagship Snapdragon 810, while the GPU graphics performance is close to that of the previous generation Snapdragon 808 during this period. It is used for screens with 1080P, and the performance is not a problem at all.
The core tuning of the X7 is similar to that of the Samsung A9. Generally, only two A72 cores can be opened, but they remain on the medium and high frequency line for a long time, with stable performance. The CPU and GPU can bake the machine at the same time. In the first 30 seconds, there can be four big cores 1.6G+four small cores 1.4G. Since then, the big core fluctuates between 1.3-1.6G. In the last 180 seconds, it has stabilized at the level of two big cores 1.6G+four small cores 1.3G and kept running. When the power is less than 10%, it will be limited to the frequency of 1.2G of four small cores. After 450 seconds of full force copying, the maximum temperature is 87 degrees, and the temperature control is milder than that of the same platform.
photograph
The vivo X7 is equipped with a 13 megapixel rear camera with an aperture of f2.0. Its photographing interface is relatively simple. The setting items and photographing functions are put together. Next to the shutter is a filter. The right side of the focusing frame can quickly adjust the exposure. The focusing speed is medium to slow, and the shutter response is very fast, but the processing speed of HDR and night scene algorithm is average.
The HDR algorithm uses less force and has a natural effect. No ghost problem is found, and the white balance does not drift. It performs well.
Rear camera imaging saturation The degree is slightly high, the color is rich, the white balance is slightly cold and green, and the metering is accurate. There is a slight sharpening effect in the amplification of the sample sheet, and the analytical power is medium to high. The noise at the fine points is well controlled, but the edges have some deterioration problems.
Vivo claims that this time it cooperates with Arcsoft of the United States, and X7 adopts the second generation compound eye anti shake and night view enhancement algorithm. Because there is no optical anti shake, the machine can only play ISO under light and weak light. However, even if the night view mode is turned on, the film rate of the machine is higher than that of ordinary models.
The discrimination in the light scene remains intact, and even in ultra weak light, there will be no obvious noise. Although there is still a certain distance from the flagship, and there is a certain probability of defocusing under extremely weak light, the performance is much better than expected.
In terms of selfie, the vivo X7 is equipped with a 16 million pixel front camera with an aperture of 2.0, which is higher than the rear camera. It is also equipped with a Moonlight soft light, which can significantly increase the brightness of the image and skin redness when turned on in dark light. Of course, the conventional function is to allow users to ignore the bad environment of backlight.

In the actual photo sample, the X7's performance is amazing, and the white balance and skin color performance greatly crush the iPhone native camera. In the test, Sister Paper also said, "Who else can take photos with the camera of iPhone? It's so ugly"

Even with Meitu's iPhone 6s Plus, its details, white balance and skin The color adjustment is totally different from the same dimension. The combination of 16 million pixels and soft light is better than expected.
Endurance&Heating&Charging
The vivo X7 is equipped with 3000mAh batteries. After 30 minutes of large-scale games (NBA 2K15), 30 minutes of wifi and 4G Internet access, 1 hour of music playing and 30 minutes of local video playing, the remaining power is 64% after a full three hour endurance test. The performance is better than that of the previous generation, but worse than that of the Xplay5 and this generation.
Top to bottom, left to right are the charging heads of vivo X7, Le 2, Meizu PRO 6 and Xiaomi 5
The vivo X7 supports dual engine flash charging, and the actual charging power is about 14.2W. The charging heads of Le 2, Meizu PRO 6 and Xiaomi 5 can also be charged quickly at a high voltage of about 14W, with good compatibility.
From 5% to 100% charging, it takes half an hour to 48%, 45 minutes to 70%, and 1 hour to 90%. It takes 1 hour and 30 minutes to fully charge, and the performance is excellent.
In terms of heating, after 20 minutes of NBA2K15, the maximum temperature at the front of the fuselage is about 43.6 degrees, and at the back is about 39.7 degrees, which is normal.
summary
Vivo's "practicality first" design philosophy is often reflected in products. For easy to use functions and settings, Vivo almost always incorporates them into its own system. Therefore, both the system UI and the hardware design are the result of taking the advantages of each other, and there are few problems in the maturity.
In the Vivo X7 generation, it is equipped with a processor that is several files better than the previous generation, and a front camera with violent specifications, combined with a front flash, making it one of the most powerful mobile phones for self filming. In addition to the endurance, rear camera and color accuracy, there is really nothing to be picky about in terms of fluency and workmanship. Our assessment of vivo X7 is also special - it is now "the best self timer among the best machines, and the best self timer among the best machines".
