The thinnest vivo X3 evaluation in the world? Appearance article

The engineering prototype of vivo X3 obtained this time is black before and blue after. Compared with Fang Zhengzhi's design, and the fuselage thickness of 5.75 mm, it gives people a strong industrial atmosphere. This is different from the round Korean design of vivo X 1.

▲ The screen border is actually black, and the flash reflects light, resulting in color difference. If the official version can be replaced with matte material, the overall feeling will be better. Vivo X3 continues to adopt a three-stage back cover design, and the middle part is made of stainless steel, and the matte paint improves a lot of overall feeling.

▲vivo X3 adopts a three-stage back cover design. From this point of view, the vivo X3 is still equipped with a 3.5mm headphone jack, which is quite close to the edge of the fuselage. In use, pay attention to protection.

▲ The auxiliary microphone of vivo X3 is set at the top of the fuselage, and the buttons of vivo X3 are still silk-printed, without LED button lights. Compared with the hidden button design mode, vivo X3 does not require the user to find the button. But it's a little inconvenient to use at night.

▲ The volume button and power button of ▲vivo X3vivo X3 are located on the left side of the fuselage. These two sets of buttons are made of metal, and the corners are polished, which will be particularly eye-catching under the light. Because the key is narrow, the elasticity of the key is soft and easy to press.

▲vivo X3 supports dual card dual standby, in which the left micro SIM card slot supports TD-SCDMA 3G and the right nano SIM card slot supports GSM 2G.

▲vivo X3 According to the official introduction, in order to achieve an unprecedented ultra-thin body, it is not only because vivo X3 uses thinner parts. The internal structure of L-shaped single-sided cloth board design is also the key to breaking the record thickness. We will further study this point in the next disassembly.

▲ Comparison of parts thickness between vivo X3 and vivo X 1S: 5.75mm fuselage, and the technological innovation of vivo X3 proves once again:? All records are used to break?

System article 1: innovative intelligent awakening somatosensory technology

In terms of system, vivo X3 adopts its own Fun-Touch dual UI system based on Android 4.2. 1 deep optimization. Because vivo has always been aiming at the improvement of intelligent somatosensory and audio playback, its system is relatively closed and does not meet the needs of user customization.

▲ When the screen is closed, you don't need to unlock it. You can open the state shown on the right by sliding your palm on it. The black-and-white interface saves electricity, but it also gives vivo models an advantage in system matching and upgrading. The new features upgraded in the flagship model can be popularized to mainstream and entry-level models to the maximum extent. In sharp contrast, HTC and MOTO are two established giants. Many experienced players remember that the non-flagship models of these two companies rarely get official updates. Users have to look everywhere for third-party systems to optimize their machines.

▲ In the screen lock interface, drag the screen to the right to open the camera, and drag it to the left to see the weather. The system adopted by vivo X3 is quite consistent with the flagship model vivo Xplay. The relatively closed system development environment ensures compatibility and stability. The popular features in the flagship model are almost completely accepted by vivo X3.

▲ I like the small screen mode very much. Vivo X3, with menu, home page and back key, configured with 1GB RAM. However, from the actual use, the fluency of the system is still ideal, even when the animation transition effect is fully open.

▲ The new picture/movie preview arrangement also supports desktop video playback, and the icons in the vivo X3 setup menu are flattened. If only desktop icons could be designed in this way.

▲ The setting menu is more concise. Vivo X3 provides two new desktop themes, but I think there are still too many designs. Heavy taste? Now, I expect the official version to have a fresher and more attractive theme style.

▲ The rich theme element vivo X3 loads a brand-new scene theme named? Different dimensions? With background music, he is very suitable for being a handsome boy.

▲ Holographic projection effect However, if you think that the system of vivo X3 is just a simple improvement, it is wrong. Next, let's take a look at the innovative and practical intelligent wake-up somatosensory technology of vivo X3.

▲ Innovative somatosensory technology? Intelligent wake-up ▲ Intelligent wake-up operation demonstration

Through intelligent wake-up, users can directly open commonly used functions without unlocking the screen. These gestures are easy to remember. If users can be provided with customized options in future upgrades, the practicability will be further improved. For example,? W? Is to wake up wechat, and then what? x？ Is Sina Weibo.

System 2: XT Studio, a mobile recording studio system.

Compared with vivo X 1/X 1S, vivo X3 has a further understanding of mobile music. Because it provides users with a mobile recording studio system? Xtudio. This system includes four parts: music radar (search), ES90 18 DAC chip (listening), iMIC (recording) and singing (sharing).

▲ Correctly recognized the Moon River sung by the author.

For users, the latter two functions make mobile music no longer limited to? Listen. You can also make your own music and find a platform to relax your voice.

Vivo x3 adopts a microphone with a signal-to-noise ratio of 65dB (57dB for ordinary microphones) and a bandwidth of 20~20000Hz. The human voice frequency is about 100~8000Hz, which can realize high-fidelity recording. Of course, using a better external microphone can also achieve better results.

▲ Monorail recording, you can also choose reverberation effect ▲ The author directly uses the microphone on the standard XE600 earphone to record.

You can't sing without accompaniment, but not all songs will have accompaniment versions. With vivo X3, users only need to click on their favorite songs, and the vocals of the songs can be eliminated, leaving only the music accompaniment. Of course, the quality of these accompaniment will vary according to different songs.

▲ It takes some time to change the accompaniment. IMIC can also support multi-track recording and edit each track. For users who like chorus, they can record music with richer levels.

▲ Suitable for multi-person chorus mixing. It can be seen that iMIC is not a simple recording function, and the author also tried it.

▲ Build your own album. I feel that no one has discovered your musical talent. You can try it here. Vivo X3 has customized the most popular mobile phone KTV, where you can post your own recorded music to share with you. You can also sing with your favorite netizens, and maybe it will become popular soon.

▲vivo X3 Customized Edition Sing it.

▲ Basically, you have all the songs you should have.

▲ After singing, the system will give you a score. Users can edit or sing again before uploading. Because of the dead of night, the author couldn't open his throat and sing. He didn't experience the effect of iMAC and singing. Judging from the author's trial for a period of time, the accompaniment made by iMIC needs more optimization, because the vocal part of the accompaniment is still obvious. Secondly, we should choose better recording equipment.

In contrast, the author prefers to sing with a lot of accompaniment music, which is simpler and easier to use (the author is really not the material for music production).

Performance: Better power consumption and heating control.

Vivo X3 uses a MT6589T quad-core processor with a clock frequency of 1.5GHz, and is equipped with 1GB RAM and 16GB ROM. This combination has been used by other manufacturers on the 1080P model with higher performance requirements more than once, so I am not worried about the performance of vivo X3.

▲ Is the 1GB RAM of Ann Bunny 4.0vivo X3 enough? The author noticed that the available memory of vivo X3 is about 380MB when it is in standby. When running Escape Hall 2, Despicable Me, Player and Weibo in the background, the available RAM is about 2 10MB, and the system fluency has no obvious influence. In contrast, the resources occupied by the 720P platform are far less than those of the 1080P platform.

▲ 1GB RAM is still an MTK platform that can meet the needs of vivo X3. It has always performed well in terms of power consumption, even the vivo X3 with a 5.75mm body is no exception. In a room at 26 degrees Celsius, after baking the machine at full load, the core temperature stabilized at 40 degrees Celsius.

▲ The heating of ▲vivo X3 is relatively balanced, and the receiver position is slightly higher than the button area. Let's run two parkour games: Escape from the Temple 2 and Despicable Me to see the game performance of vivo X3.

▲vivo X3: The highest quality demo of Escape from the Temple 2.

▲vivo X3: despicable me to demonstrate.

Screen article: 5.0 inches to catch up with the big screen trend

Vivo X3 uses a 5.0-inch IPS screen with a resolution of 1280? 720, 293PPI per inch of pixels, belonging to the retina screen level. Limited by the thickness of the fuselage, will the display effect be discounted?

From a visual point of view, vivo X3 is quite satisfactory, and it is ok for three users to get together and gossip about Weibo WeChat.

▲ Click to enlarge. In the following comparison, as vivo X3, on the right is a brand's 5.0-inch 1080P model (440PPI per inch pixel).

When browsing pictures, the difference between 293PPI and 440PPI is not obvious. In addition to the text in the picture, you need to compare it carefully to feel the advantages brought by high PPI.

However, when browsing the web, the higher PPI brings a lot of exquisiteness.

▲ Click to enlarge. Although vivo X3 is a smart phone focusing on mobile music, its screen display effect can still meet the current demand. At least when watching pictures and movies, you can kill the iPhone 5 that stays at the level of 4.0 inches (320PPI).

Photo: Independent Focus and Photometric Point

Compared with previous models, vivo X3 is well prepared. Arm? . First of all, the photo modes that can be selected are more abundant, and practical functions such as night scene and beauty are added.

▲ When using the main camera in vivo X3 camera interface, long press the screen to bring up the independent focus point (square) and metering point (circle). You can lock the focus before taking a picture, and then get the ideal exposure by moving the metering point, which is suitable for people.

▲vivo X3 camera interface According to the official introduction, the camera of vivo X3 uses a closed-loop motor, and the focusing speed is nearly twice as fast as that of ordinary models. The author compares it with Meizu MX2 and finds that the focusing speed of vivo X3 is really fast.

In fact, focusing speed is also a key factor in taking pictures. It can determine whether users can capture more moments, so we will conduct in-depth tests in this area in the future. Let's take a look at the sample of vivo X3 first.

DAC chip ES90 18 was imported from ESS company of America, and vivo X3 used low-voltage version ES90 18MK2. This is a top-level high-fidelity 8-channel digital-to-analog converter, which supports 192kHz/32bit sampling, with a signal-to-noise ratio as high as 127dB and a distortion lower than-120dB.

▲ES90 18 However, because it is an engineering prototype, I feel that the machine is still being debugged when listening to the audition with vivo X3 in my hand. When upgrading to 1.7. 1, I tried a variety of headphones but couldn't find a suitable match.

After upgrading to 1.7.2, this situation began to improve. At this time, the overall performance began to stabilize, but through the vocal audition, I feel that the engineers of vivo are still persistently pursuing better debugging results.

It takes time to debug the sound quality of vivo X3. At present, the feeling is that ES90 18 can bring better vocal performance. In addition, the sound field becomes wider and it is worth looking forward to.

Editorial comments

It's not easy to pursue the ultimate, but vivo X3 did it. Record-breaking ultra-thin body, the first mobile recording system, and the somatosensory technology in the locked screen state. Vivo X3' s courage to abandon the mature Hi-Fi audio chip combination and seek better performance is really commendable.

▲vivo X3 However, vivo X3 still needs to be improved, and the response speed of intelligent wake-up should be more sensitive; It's time to make a breakthrough in the theme style; Debugging for ES90 18 has a long way to go.

The price of Vivo X3 is 2498 yuan, and its competitive advantage is quite obvious. After all, in the same price model, no one can compare it with industrial design, system function, sound quality and earphone accessories. Of course, running separately is another matter.

Therefore, the author thinks that vivo X3 is a product with comprehensive performance and suitable for comprehensive recommendation.
