Less than eight months after the previous generation X6 was released, vivo released the vivo X7 on June 30. This is the very few products in vivo that use the number "7" as the code name. The new aircraft is equipped with this year's U-Long 652, the battery was upgraded to 3000mAh, equipped with a 16-megapixel front camera, switch to a pre-fingerprint identification program and redesigned the entire front. What will be the performance of X7 after the big change? Let's take a look now.
The evaluation mainly focused on the appearance of workmanship, performance, system and frontal fingerprint identification programs, photographing and battery life.
parameter
Vivo X6/X6 Plus and X7/X7 Plus parameter comparison table
Vivo X7 uses pure white carton packaging, the first layer of the packaging is the machine, the lower layer is a very rich accessories, including in addition to flash charge head, data lines, card pin and headset, there are two different colors of water jacket, film . In addition, the machine has been attached to a film when it leaves the factory. Buying back basically eliminates the need to buy other accessories.
The charger supports 5V2A and 9V2A output, the nominal maximum power is 18W, and the size and weight of the charger are larger than conventional manufacturers such as Xiaomi/Meizu.
The front of the new machine is a very popular rounded rectangle + ellipse Home button design this year, although there are certain black edges, but the overall frame is relatively narrow, looking very pleasing to the eye, but it is also very easy to hit the face.
At the top are a 16-megapixel front camera, an earpiece, a light/distance sensor, and a moonlight front soft light highlighted in this event.
At the bottom is the Home button that supports fingerprint recognition, with the backlit menu key and back button on both sides.
The back is a vivo-style design, all-metal one fuselage, there are two antenna partition bars up and down, there is a circle of polished chamfer around.
The top is the camera and flash, and the bottom is simple body information.
The right side is the volume and power button, the left is the sim card slot, supports two nano-SIM cards but does not support TF card expansion. The side can see the machine edge is more rounded, and the front 2.5D glass curvature extends to the screen, the screen edge has a relatively high circle of plastic washers.
The bottom of the fuselage are the headphone jack, microphone, mirco-USB interface and speakers. The number of openings is more, but at least they are on a horizontal line.
Work & Touch & Fingerprint Identification
The machine's workmanship is still familiar with the taste of vivo: button virtual small, press the springback simply; all-metal integrated sim Cato slightly lower than the fuselage, combined compact no virtual position; positive Home key slightly lower than the screen, The cover plate and other parts of the zirconium zirconia material are even more white, and the press feels solid, with no squeaking noises, and the bright side of the back is even curved, and the workmanship is impeccable.
Throughout the entire new machine appearance of the keyword is "round", more curvature of the border, the back of the more obvious corner, a lot more than the metal frame of the washer and 2.5D glass, so that the machine can be very close to the palm of the tiger's mouth. The 5.2-inch screen and the narrow frame bring a very good one-handed operation.
The previous-generation vivo X6 had a record-breaking back-fingerprint recognition speed, and this year's X7 was changed to a frontal fingerprinting program, but the unlocking speed was still exaggerated. In the case of lighting the screen, the moment of contact can be completed to unlock; in the state of the information screen, the speed is “slightly slower†than that of the bright screen, but it is less than half a second, and after the touch, it can quickly close the hand, and the machine can still finish. Unlock.
The unlocking speed is far more shocking than the nominal 0.15/0.2 seconds. It is almost impossible to feel the fingerprint lock for daily use. The only one that can match the speed is OPPO R9. In addition, touch the home button or press directly to unlock, everyday use without pressing the power button, it is more convenient to use.
The Vivo X7 uses a 5.2-inch Super AMOLED screen, but there is no mechanism for increased brightness in bright light. We obtained the highest central brightness of 343 nits in this test, and the reduced display area can increase the local brightness to 400 nits.
The upper screen brightness is about 380 nits, the lower part is about 330 nits, and the backlight uniformity is normal. On the naked eye, the color temperature of this AMOLED screen is cool, and the hair color is thick and bright. It is relatively flattering to the eyeball, but the color standard is quite satisfactory.
Vivo X7 is equipped with Funtouch OS 2.5.1 based on Android 5.1. The new system has not changed much. The unique features of the Funtouch OS include a single-layer desktop, iconic flat wind icons, a multi-tasking manager's pull-up bar, a simple setup menu, and rich somatosensory operations and advanced features. Detailed design and function settings can be viewed before the system evaluation, not repeat them here.
Funtouch OS's optimization has been good, and many low-performance machines can run quite smoothly before. The X7 equipped with Xiaolong 652 has no reason to get stuck. Whether the machine is swiping or responding quickly, the GPU rendering curve is far more than 60 frames of smooth lines, and the actual experience is very smooth.
The main changes in 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. The direct effect is that the entire screen is yellow. The latter allows the home button to add double-click shortcuts to activate the camera, flashlight or WeChat, QQ features.
The previous multi-tasking split-screen function has also been enhanced. In some applications, the three-finger slide can trigger split screens. But the main limitation is in reading and video applications. The screen ratio can be dragged on its own to support Hengping. After dragging and dropping one side of the screen, the other app will appear as a hover icon.
In addition, what is more special is that X7's touch keys are triggered by loosening the hand. To respond quickly, you have to let go quickly. This is not the same as many machines. The home button touch or press is the trigger to return to the homepage, users who used the traditional Andrews machine or the iPhone can adapt quickly, but if you have used Meizu or ZUK mobile phone users may take some time to adapt.

Flash read and write performance
The vivo X7 is equipped with Qualcomm Snapdragon 652+4G LPDDR3 memory +64GB storage. The CPU of the Nine Dragons 652 consists of four 1.8G A72+4 1.4G A53s, and the GPU is Adreno 510@624MHz. Xiaolong 652 is one of the biggest dark horses in the SoC market this year. It has appeared on the X6S Plus voyage version, Xplay5 standard version, and millet Max models. I believe everyone is familiar with its performance. The Xiaolong 652's CPU computing performance surpassed that of the previous generation flagship Xiaolong 810. The GPU graphics performance was similar to that of the previous generation Xiaolong 808. Used to bring a 1080P screen, performance is not a problem at all.
The core tuning of the X7 is similar to that of the Samsung A9. Generally, the A72 core will only open two, but they will maintain the mid-high frequency online for a long time and the performance will be stable. The CPU and GPU can be roasted at the same time. In the first 30 seconds, four large cores of 1.6G+4 small cores can be used for 1.4G. After that, the large cores oscillate between 1.3-1.6G, and the 180s finally settle on two large cores of 1.6G+4. The core 1.3G level has been running. When the power level is lower than 10%, it will be limited to the frequency of four small cores 1.2G. After 450 seconds of full press, the maximum temperature is 87 degrees, and the temperature control is milder than that of the platform.
Taking pictures
Vivo X7 equipped with a 13 million pixel rear camera, f2.0 aperture. Its camera interface is relatively simple, setting items and camera functions together, next to the shutter is a filter, the right side of the focus frame can quickly adjust the exposure. The focus speed is slow and the shutter response is very fast, but the HDR and night scene algorithms are generally fast.
The HDR algorithm is lighter and has a natural effect. No ghosting problem has been found, and white balance has not drifted. It performs well.
The rear camera has a slightly higher image saturation , richer colors, slightly cooler white balance, and accurate metering. Specimen magnification has a slight sharpening effect, and the power of discrimination is middle and upper, and the noise at fine details is well controlled, but the edge has a certain problem of deterioration.
Vivo claimed that this time with the United States Arcsoft company, X7 uses the second generation of compound eye anti-shake and night scene enhancement algorithm. Because there is no optical image stabilization, the machine can only use ISO under light and low light. However, even if the night view mode is turned on, the machine's filming rate is higher than that of the ordinary model.
The resolution in the lighting scene remains intact, and even in the case of ultra-low light, it will not be very noticeable noise. Although there is still a certain distance from the flagship, and there is a chance of defocusing under very low light, the performance is much better than expected.
Self-timer, vivo X7 equipped with a higher than the rear camera pixel 16 million pixels front camera, f2.0 aperture, and equipped with a Moonlight soft light, dark light can significantly increase the screen brightness and skin redness, of course The conventional role is to allow users to ignore the adverse environment of the backlight.

In the actual photo proofs, the performance of the X7 was stunning, and white balance and skin color performance all crushed the iPhone's native camera. In the test, Sister Paper also stated that "Who else will use the iPhone to take pictures with the camera, so ugly"...

Even the use of Mito iPhone 6s Plus, details on adjusting the white balance and skin tones are completely outside on a dimension. 16 million pixels + soft light combination, the effect is even better than expected.
Vivo X7 is equipped with a 3000mAh battery, after 30 minutes of large-scale game (NBA 2K15), each 30 minutes of wifi and 4G Internet access, 1 hour of music playback and 30 minutes of local video playback, after a full 3 hours of battery life test, the remaining power of 64% . Performance is better than the previous generation, but worse than Xplay5 and this generation of models.
From top to bottom, left to right are charging heads for vivo X7, music 2, Meizu PRO 6, and millet 5.
Vivo X7 supports dual engine flash charge, the actual charging power is about 14.2W. The use of music 2, Meizu PRO 6, the charging head of millet 5 can also be about 14W high voltage fast charge, good compatibility.
Charging is from 5% to 100%, 48% to half an hour, 70% to 45 minutes, 90% to 1 hour, and it takes 1 hour and 30 minutes to complete.
In terms of heat, 20 minutes after the NBA2K15, the body's maximum temperature was 43.6 degrees, and the back was about 39.7 degrees. The performance was normal.
to sum up
Products often reflect vivo's "practical first" design philosophy. For good features and settings, vivo will almost completely integrate into its own system. Therefore, whether it is the system UI or the hardware design, it is the result of adopting each family's long-term results. Maturity rarely encounters problems.
To the vivo X7 this generation, equipped with a number of files stronger than the previous generation of processors, as well as the specifications of the violent front camera, with the front flash, so that it became one of the strongest self-timer phone. In addition to battery life, rear-facing cameras, and standard performance, the fluency and workmanship performance is really not that critical. And our evaluation of the vivo X7 is also quite special - it is now the best of the best self-timer machines, and the best self-timer in the best machine.
