After APEX and NEX, vivo began to emphasize the sense of design very clearly, and then we saw the X23 of the water drop screen+hidden infrared fill light+aurora rear cover. Although vivo rarely emphasizes configuration, software and hardware of X23, including SoC, CMOS and wide-angle sub photography, face pinching and body beautification, endurance, and charging, have been enhanced to varying degrees from the Jovi button inherited from the entity on the flagship NEX, the 10V 2.25A half voltage flash charging scheme, to the Super HDR on the full screen concept machine APEX.

X23 uses Samsung's AMOLED screen in cmd mode. The specific model is dsi_pd1809_sofeg04_1080p_cmd_display. This one is Huiding's screen fingerprint and Xinsi's touch IC. Vivo is still used to calling the new DAC AK4377A in HiFi mode. Usually, Qualcomm's WCD series processing is used.
appearance
X23 is replaced with the same 10V 2.25A semi voltage flash charger as vivo NEX, model V2323A. Other accessories include XE710 earphone, silicone shell and factory film. The ex factory silicone shell has been replaced with a full soft shell material, and the corner protection has been significantly strengthened, which will make it feel thicker.
The biggest change on the front of the X23 is that it becomes a water drop screen/beauty tip, and the arc on the screen edge is larger. The chin is slightly narrower than that of the X21, and the overall effect is a bit close to NEX. The biggest advantage of the water drop screen is that, in addition to being more comfortable in appearance, it finally has a normal notification bar, and the possibility of notification being blocked by a missing window in the middle is very low.
The X23 infrared fill light is hidden on the top, and the infrared point on the left is the distance sensor
Infrared face recognition: Vivo X23 is the first and only water drop screen mobile phone with infrared face recognition 。 There are two key points here, and they are all very hidden innovations:
First, the narrow forehead should not only have a receiver, but also an infrared fill light for dim face recognition;
Secondly, normal cameras and infrared cameras cannot replace each other because of different filters, so infrared face recognition normally requires two cameras. The X23 solution uses the industry's first RGB compatible front camera capable of infrared face recognition.
Fourth generation screen fingerprint: The screen fingerprint that has become the standard configuration of vivo is the fourth generation on vivo X23. It adopts the same wide-angle camera scheme as NEX, with image recognition accuracy of 750 DPI, f/1.5 aperture, and the recognition rate of the declared limit case is increased by 40%.
If nothing unexpected, the X23 is the most beautiful vivo mobile phone now, and its maximum bonus comes from the back cover. The official "ultra strength coating technology" has printed countless texture lines 70 microns wide and 10 microns deep on the color sticker layer below the glass, so as to achieve the curved surface streamer effect in a specific direction.
We got this Phantom Purple color matching, which is a typical "Ming Sao" style, with an oblique gradient effect from purple in the lower left corner to red in the upper right corner. Because a layer of 100 nm silver coating is superimposed, this gradient texture can show water rippling aurora texture without strong light source.
The vivo X23 publicity uses the industry's thinnest metal middle frame, which is only 2.68mm thick, and the volume and power keys are also quite slender. But the most important improvement is actually the screen washer, which is the first time we have seen such a complex screen washer. The shape and contour of the gasket are directly connected with the radian of the screen and the middle frame, which is the number one contributor to the improvement of hand feel.
Another thing that is very similar to NEX is that the X series has also added the physical keys of Jovi intelligent voice assistant on the left, and has retained the headphone interface. Because of changes in screen and border controls, vivo X23 is taller and narrower than X21. With the curved back cover and the screen gasket treatment, the X23 has an unparalleled touch in this screen size mobile phone.
The appearance, if you want to say anything, is that this mirco USB interface appeared in 8102.
screen
6.41 inch 1080 * 2340 19.5:9 water drop screen. The specific model is Samsung dsi_pd1809_sofeg04_1080p_cmd_display. In the standard pentile arrangement, the converted PPI is 328. The actual appearance and objective parameters of this screen are very close to vivo X21, both of which are high saturation types of eyeballs. The advantages are high contrast, visual angle, color gamut, and typical appearance flow.
Full white maximum brightness is 397 nits, and local maximum brightness is 509 nits. There is no strong light excitation mode. The test is carried out at a brightness close to 100 nits in daily use. The default color temperature is 7705K, and the cold screen. It can cover 94.6% of P3 color gamut and 128.5% of sRGB color gamut.
P3 color standard of 104 colors of the machine, the average deltaE is 5.9, and the maximum is 11.4; SRGB color standard, the average deltaE is 7.2, and the maximum is 13.3. The color accuracy performance is average, and it still follows the rich and colorful high saturation style, but it is obviously adjusted according to the P3 color gamut. After all, the default rendering of the system is P3 color gamut.
performance
From the choice of vivo and OPPO, it is not 710 but 670 AIE that succeeded 660 dragon gods. The latter can be understood as the "youth version" of Snapdragon 710 in CPU/GPU/baseband. Focus on the core upgrade features:
It is also the most advanced 10nm LPP process, which is one level higher than the old flagship Snapdragon 835;
CPU and ISP are the same generation architectures of Snapdragon 845, respectively Kryo 360 and Spectra 250;
The DSP is directly the same type of Hexagon 685 DSP as Xiaolong 845;
The memory has also been upgraded to dual channel LPDDR4x, and even supports QC 4+fast charging.
Compared with the flagship Snapdragon 710, the CPU and GPU main frequencies are lower, and the baseband is X12, just like the Snapdragon 660 AIE. The GPU frequency is 750MHz to 650MHz in the previous news, but 500MHz to 430MHz is actually measured.
The core upgrade of this SoC is not performance, but power control. Daily use fluency is not a problem. "Survival of the Jedi: Stimulating the Battlefield" is still set at 30 frames of high-definition picture quality consistent with the Snapdragon 660 AIE because it has yet to be optimized by the developer. While the performance slightly surpasses that of the previous generation, this is really a cool SoC. The CPU toaster does not have frequency reduction for 6 minutes
The CPU performance of X23 is better than that of other Snapdragon 670 AIEs. The GPU performs normally, and its flash memory is also upgraded to UFS. The flash memory performance is significantly improved compared with the previous generation.

system
The vivo X23 is equipped with Funtouch OS 4.5 based on Android 8.1. The security patch is very new until August 1.
First of all, the new UI theme color matching is faster, and the various ground glass effects under the colored background are quite OK. It has been one of the official themes of Vivo in all ages, and Jige likes it best. But I really don't know whether to be happy or sad
Second, Jovi Voice Assistant can now automatically filter modal particles such as "Hmm, ah, that, and then", and also supports scheduled reservation operations. The reservation operation can be used for the dream of sending WeChat messages regularly. However, it may be for security reasons that Jovi needs to vibrate to remind the user when the task is to be executed, and only after manual confirmation can the operation be executed.
The third is unlocking. The fourth generation screen fingerprint of vivo X23 has a certain improvement in absolute speed compared with NEX. Personally, the main improvement is more about recognition accuracy, and now it can be unlocked without additional pressure. However, the recognition rate still needs to be further improved. Screen fingerprints do not have the tactile feedback of traditional fingerprints, and the requirements for recognition rate are even higher than before.
Face recognition, which used to be a second solution, is one gear faster in X23. If it weren't for the unlocking "light effect" at the edge of the screen, you would mistakenly think that you forgot to open the face recognition
There is also a "fingerprint face combination unlocking" function, which is basically equivalent to using the sensing area of the screen fingerprint to trigger the face unlocking. Because the fingerprint area on the screen is bright, it will be a new choice for users who are not accustomed to clicking the power button, and it is faster than simple screen fingerprints.
Primary and secondary photography
X23 This time, the main camera is the Sony IMX363 (full pixel dual core focusing, 1.4 μ m) , F1.8 aperture. Compared with the flagship, the main difference is optical anti shake.
Super backlight mode
The Super HDR super backlight of the X23 is a mass production technology of the Super HDR on the APEX of the concept machine. It claims to be able to achieve 12.3EV dynamic range. In the ordinary sunset scene, its dynamic range effect is close to what the naked eye can see, but it is obviously different from many violent HDRs that exert too much force.
Automatic super backlight
Face light scene
The super backlight mode will determine the intensity according to the scene. In the scene with small light difference, only slight dark differences will be seen.
Light backlight scene 1
Light backlight scene 2
Strong backlight scene, very obvious dark part brightness and detail improvement
Light scene 1, pay attention to the edges and color saturation at highlights
Light Scene 2
The X23's super backlight mode is one of the strongest HDRs among domestic mobile phones. If the requirements for imaging speed are not high (HDR will prolong the imaging time), it can even be normally turned on. In the backlight scene, the most obvious improvement is the dark part detail. The backlight dark part seems to have additional light, and there is no obvious edge transition problem. Even if the object moves slightly, there is no ghost. In the night scene with complex light, the super backlight can also play a significant role in such scenes as high brightness neon lights and signs. In addition to the dark details, the highlight suppression and overall color saturation in the highlight mode are far better than those in the normal mode.
In the normal imaging part, the white balance of X23 is very stable, the contrast and saturation are slightly higher than that seen by the naked eye, obviously pleasing the eye. The ancestral noise reduction of vivo is unlikely to see large noise spots in details, but the ultimate discrimination will be affected.
There is no doubt that the main camera of the X23 is the best performance of the X series in the past, and it is also one of the best performance among the products of the same scheme. Of course, it would be better if optical anti shake blessing could be available next year. Even though most users rarely take photos in extremely low light, optical anti shake is still an important function to save countless "stars who shake their hands when taking photos", which can save many photos.
Wide-angle subphoto
Speaking of wide-angle sub photography, we have to mention LG. Its sub camera was used earlier than the iPhone 7 Plus, and it is the only manufacturer that has always adhered to the wide-angle end. However, LG mobile phones have withdrawn from the domestic market.
The X23 sub camera lens has a 125 degree wide angle, which is about 11mm equivalent focal length. By default, wide-angle distortion correction is enabled in the factory. After correction, the wide-angle is 109 degrees, which is about 15mm equivalent focal length. In contrast, the widest range of normal mobile phones is 24mm, while the iPhone is generally 28mm. The difference can be seen at a glance.
Wide angle correction is enabled by default, and wide angle distortion can "straighten" most lines

Close shot 2, comparison of main camera and auxiliary camera fields
Users who first contact the wide-angle sub camera will surely be shocked by this vision. Although the X23 narrows the wide angle for practicality, not reaching the level of LG's 135 degree fisheye lens, the actual effect is still immediate. In addition to the building and natural scenery scenes that are the territory of wide-angle lens, large wide-angle lens is very suitable for group photos in narrow K rooms or small shops.
However, wide-angle sub photography is not invincible, because the number of pixels is fixed. The wider the field of view, the smaller the number of pixels that can be divided into units of scenery, and thus the discrimination will be reduced. Also, because of the difference in the scene within the field of vision, there will be some differences between white balance, metering and photography. But Gangzhen, in front of the playability of Jiaoduan, these are the second.
Pre selfie
X23 is 12 million pixels in front, and F2.0 aperture. In theory, the lens module that can recognize infrared images will affect the photometry and white balance because of the infrared light. However, no abnormality was found in the front live shot sample of X23, and the performance was normal.
"Radiance camera" and "body beauty" function
Face pinching routine of "face brightening camera"
The beauty and body camera should be the upgrade that female users are more concerned about. Officially, the former is known as the "face brightening camera", which is commonly used to cut faces, thin faces, thin noses, long noses, big eyes, eye distance, mouth shape and chin. This is more than just pinching the face. Plastic surgery is no problem.
The thin waist, thin legs, long legs, shoulder adjustment and hip beautification in body beauty are exaggerated. The main principle should be that AI recognizes the human skeleton structure, and then compresses or stretches it at a specific position. In the actual test, even if the target is deliberately moving slightly, there is no problem in recognition. In addition to body beauty, if you don't have a strong desire for survival and want to revenge your girlfriend, this function can also be adjusted in the opposite direction (manual funny).
There must be a lot of people who want to buy those phones that focus on beauty, but when they see the appearance, they will sincerely say "Excuse me". The X23 is the most beautiful, or the most mainstream aesthetic, mobile phone with such beauty features.
It is said that the proportion of female users of the vivo X series has exceeded 70%. This time, the target users of the vivo X23 are very obvious for its selfie, beauty and body enhancement. In the X23 camera, there are really many things that we can never understand
Endurance&Charging
The X23 is equipped with 3400mAh battery. After 30 minutes of large-scale games (NBA 2K15), 30 minutes of wifi and 4G Internet access, and 30 minutes of local video playback, a total of 2 hours of endurance testing, the remaining power is 83%. Although the battery capacity is smaller than that of the NEX with 4000mAh, the final endurance is still equal to that of the NEX, which is significantly improved than that of the X21. The endurance of Snapdragon 670 can really do whatever you want.
X23 is equipped with the same 10V 2.25A semi voltage flash charge scheme as NEX. The feature of this scheme is that it does not need to pick up wires, and ordinary data lines can also be used, but it needs its own fast charging head (only NEX and X23 can be used for the time being), and it is not compatible with QC fast charging. Other fast charging heads can only be 5V2A. But the advantage is that the speed is really fast and the heat is not too high. Even if the power is 65%, it can still be about 20.5W, and the output is very positive.
From 5% to 100% charge, it takes 15 minutes to charge to 37%, 30 minutes to charge to 63%, 45 minutes to charge to 85%, and 1 hour to charge to 96%. It takes 1 hour and 16 minutes to fully charge.
The new semi voltage flash charge should make the X23 3400mAh battery look like a bag of tea. The time of key nodes is shortened by half compared with the previous 5V2A "fast charging". If calculated by the number of mAh charged, NEX and X23 are the fastest among the new fast charging schemes that can use ordinary data lines, and probably none of them is available.
In terms of heating, the room temperature is 26 degrees. After 20 minutes of NBA 2K15, the highest temperature on the front of the machine appears on the left side of the top, about 41.0 degrees; The highest temperature at the back appears in the camera area, about 38.5 degrees. The overall temperature is not high, and there is no local high temperature. The heating and heat dissipation performance is good.
Summary
If NEX is the most handsome mobile phone in vivo, X23 is the most beautiful mobile phone in vivo. If the NEX is the most powerful mobile phone for taking pictures behind vivo, the X23 is the most powerful mobile phone for taking selfies and beautifying the body.
The slots that can be captured by the X23 are mainly micro USB interface, screen color accuracy and Snapdragon 670 AIE, which have little absolute performance improvement. The starting is the setting of 8+128, which can also improve the threshold of starting. However, the X23's unlocking experience and power consumption control are at the level of free will, plus the half pressure flash charge and Jovi. Hong Kong Zhen, in addition to rear camera and games, X23 is even easier to use than NEX. Even if the machine guy is like me, I have to admit that X23 is really deep in my heart this time.
