IT168 Review Sony CEO Kazuo Hirai said in an interview some time ago that Sony will not withdraw from the smartphone market and hopes to become a future leader. This response positively dispelled the crisis remarks about Sony Mobile from the outside world. Judging from Sony's recent financial reports, after some adjustments in 2015, Sony's overall business finally turned a profit for the year. In the first quarter of 2016, Sony's mobile business also achieved profitability. Although the net profit was only US$40 million, it was not easy. Achieving profitability is closely related to Sony Mobile's active adjustment of its market strategy, instead of blindly expanding its scale and seeking overall profit margins.

At the product level, Sony used the Xperia Z5 to bring an end to the Xperia Z series of mobile phones that have been iterating for 3 years. Although many people feel sorry for the Z series products, what Sony Mobile must face is demand breakthroughs and changes in a fiercely competitive environment. At MWC at the beginning of this year, the launch of Xperia X, Xperia The Xperia XZ released at this year's IFA is a landmark transformation, and it also has high hopes from Sony. So can this product open up a new market situation for Sony Mobile? We might as well analyze it in detail.

Friends who know Sony must know that industrial design and hardware black technology are what Sony is good at, and these two specialties happen to be displayed vividly and exquisitely on Xperia XZ. Compared with the fully balanced design of the previous Xperia Z series, Xperia XZ adopts a new design language "UNIFIED DESIGN". The body material has been changed from the previous double-sided glass to an all-metal body (the back cover is made of magnesium-aluminum-lithium alloy). In addition, 2.5D glass and ultra-narrow frames have been added to design elements that are more easily accepted by the public, thereby changing the previous problem of the middle frame being awkward. In other words, from the Xperia XZ, we can see the design innovations Sony has brought to the industry, and we can also find the design trade-offs made by Sony.

Needless to mention the hardware, Sony Xperia XZ uses a 5.2-inch 1080P display, Qualcomm Snapdragon 820 processor platform, 3GB running memory, 64GB body storage space, 23-megapixel main camera and 2900mAh capacity Battery. Putting 3GB of running memory on a flagship phone like Sony's Xperia Will pay attention to these hardware parameters. After all, the real charm of Sony mobile phones is not in terms of hardware parameters. In addition, it is also a pity that the Bank of China does not support full Netcom.

The main selling point of Sony Xperia XZ this time is triple image sensing technology and five-axis anti-shake ( Electronic anti-shake). The so-called triple image sensing technology simply means that in addition to the built-in image sensor and laser focus sensor, the Sony Xperia XZ is also equipped with an additional RGBC-IR sensor to obtain more accurate white balance and exposure. Value. Regarding the specific imaging of its camera, we will elaborate on it in the camera section later.

Appearance and industrial design In terms of performance, Sony has always had its own unique persistence. From Sony's products, you can clearly see the strong Japanese flavor: fresh, simple, and square. These iconic design elements are also fully reflected on Sony Xperia XZ. In the next part, we will briefly explain the appearance design of Sony Xperia XZ.

On the front of the fuselage, the overall shape of Sony Xperia XZ is square and tough, with dual stereo speakers designed at the upper and lower ends. The machine uses a 2.5D glass design on the side, which, combined with the rounded arc design on the side of the fuselage, ensures a good grip on the side of the fuselage.

Different from the common 2.5D glass design, Sony Xperia XZ only uses 2.5D transition on the left and right sides of the screen glass. The top and bottom of the front of the fuselage use special processing at the connection between the frame and the glass.

As you can see, the upper and lower borders of this phone are slightly higher than the screen protection glass, and the screen protection glass looks like it is embedded in the metal body. The design with the frame higher than the screen glass is very common on Sony's previous mobile phones. The advantage of this is to prevent the glass from directly touching the ground when the phone is dropped, reducing the risk of screen breakage, but it also sacrifices the grip. This time, Sony Xperia XZ has optimized the hand feel while ensuring safety, achieving both aspects without losing its beauty.

In addition to the integrated speaker earpiece, sensor, and front-facing camera, the top front of the fuselage also has a breathing light and NFC chip (located between the breathing light and the front-facing camera). In other words, when using NFC-related functions, the part should be as close to the sensing area as possible. But another point is that Sony Xperia XZ currently only supports Google Wallet and cannot be used for payment purposes yet. The only uses I can think of are to recharge bus cards and read specific NFC chip information.

As for the top area of ??the mobile phone body, we have seen that many domestic mobile phone manufacturers use symmetrical designs to reasonably lay out these components on the top to make them look simpler. The top layout of Sony Xperia XZ is a bit messy and not beautiful in comparison. Especially when the "SONY" logo is also printed in this area, some sense of design is missing.

On the back of the fuselage, the body material used by Sony Xperia XZ is different from that of ordinary mobile phones, it is magnesium aluminum lithium alloy. This material is not only thin but also has better stability and thermal conductivity. After sandblasting and polishing, its surface has a very high metallic gloss and is not easily stained by fingerprints. Because of its all-metal body design, Sony Xperia is designed with an antenna overflow opening at the bottom and a plastic cover on the surface. This method of processing is actually not common on high-end mobile phones, mainly because it is difficult to completely match the colors of metal and plastic materials. But we can see that on the Xperia XZ mobile phone, Sony has handled it very well. The color difference between the two materials is not obvious and there is still a high degree of integration.

As for the camera, Sony Xperia XZ uses a 23-megapixel main camera. Officially, it only takes 0.6 seconds for the camera to wake up. And it has long supported the high ISO of 12800. The lack of optical image stabilization is still a pity, but video recording supports 5-axis electronic image stabilization. But the highlight of Sony Xperia XZ's camera is its use of triple image sensing technology. The "triple" refers to: image sensor, laser autofocus sensor and RGBC-IR sensor. The addition of the RGBC-IR sensor is mainly used to improve the accuracy of white balance and exposure. In the simple process of getting started, the white balance performance of the Sony Xperia XZ main camera is indeed eye-catching. Even the white balance is "scary". "The iPhone, which is known as the iPhone, has to be defeated.

Sony is one of the few mobile phone brands that insists on using side fingerprint recognition buttons. The reason why Sony does not use front or back fingerprint recognition solutions is largely due to the lack of fingerprint recognition on the fuselage. Aesthetics and integrity considerations. Due to the small internal space and the small external fingerprint recognition area, the side fingerprint recognition solution actually has no inherent advantages. However, after continuous optimization, the fingerprint recognition experience of Sony Xperia XZ has been very good in terms of speed and accuracy. It can be said to be "unlocked in seconds".

But it is still a pity that the software support for the fingerprint recognition function of this machine is not very good. In the system, it can currently only be used to unlock the screen. Sony Xperia XZ does not have functions such as album encryption and folder encryption that are common in domestic mobile phones. At present, it is only found that fingerprint login can be used for the China Merchants Bank mobile banking client, but fingerprint payment by Alipay and WeChat is not supported.

Finally, let’s take a look at the bottom of the fuselage.

Sony Xperia XZ uses a one-piece mid-frame design, with a CNC-processed groove on the bottom of the fuselage (the same on the top). The texture of this part of the bottom is actually different from that of the middle frame of the fuselage, it is smoother and more translucent. There is no official description of this part, but in terms of look and feel, it should be a piece of glass embedded in this part. Attractive to details. The USB Type C interface used by Sony Xperia XZ has obvious advantages over the traditional Micro USB interface. It supports larger charging current and faster data transmission speed. It is now very popular.

The above is an interpretation of the appearance of the Sony Xperia XZ mobile phone. It continues Sony's consistent Japanese style, simple and square. The 2.5D curved glass on the front and side of the fuselage, the rounded middle frame of the fuselage, and other improvements have not made it lose the heritage of the family design, but it has made some effective optimizations in terms of grip, which is really rare. . The excellent workmanship of the Sony Xperia XZ can leave a large number of domestic mobile phones far behind. Some domestic brands that have always regarded themselves as "craftsman spirit" are really embarrassed in front of the Sony Xperia XZ?

For the vast majority of international manufacturers, local optimization for the Chinese market has always been a headache. Since Google services are not available in China, foreign mobile phone manufacturers need to customize a set of services specifically for domestic users in order to meet the needs of domestic users. Apple and Samsung are relatively top-notch among many international brands in terms of localization, but there are still some differences in the details. Sony Mobile's mobile phone system strategy has always been to adhere to the principles of simplicity, simplicity, and smoothness, and follow the operating logic of native Android. This has resulted in the optimization of Sony mobile phone software being far from comparable to domestic customized systems.

The system of Sony Xperia XZ is modified and designed based on Android 6.0.1 version, and is expected to be upgraded to Android 7.0 version in the next one to two months. The advantage of following the light customization of the native system is that the basic functions can be guaranteed to be stable and smooth, and the version iteration speed can keep up with Android in a timely manner. The problem is that localized services with convenient details are difficult to satisfy users, and users are required to download third-party software to supplement functions. However, problems have arisen in the domestic environment. First, there is a serious phenomenon of background chain startup of applications in China, which will cause increased power consumption. Second, domestic tool software has many advertisements and an unfriendly experience. This puts the Sony mobile phone system into a very embarrassing situation in the domestic market.

Having said that, judging from the author’s current experience, installing green guardian software can improve the problem of application background startup. If combined with ROOT, better results can be obtained (ROOT is not recommended for general users. Warranty service may be lost after ROOT). However, this undoubtedly increases the learning cost for ordinary users. I hope this issue can be taken seriously by Sony Mobile and improved in the future Android 7.0 upgrade.

Sony Xperia XZ

Basic framework interface

When I first got my hands on Sony Xperia XZ, I felt that its user interface was very pleasing. like. The design is simple and exquisite, and the colors are varied and in line with the aesthetics of young people. It has positively improved the brand tone and is in line with Dafa's consistent style. After using it for a period of time, Sony's interface design also makes me feel that it is not easy to cause aesthetic fatigue. Especially for the music playback interface, it's hard to find anyone who can design it more beautifully than Sony.

Software technical support for Sony Xperia XZ

Sony Xperia XZ’s audio and display achievements are worthy of praise. Compressed audio or pictures with average color performance can achieve better performance when placed in Sony

Xperia XZ. I have to add a big rule here. In addition, if you own other Sony products, such as cameras, TVs, PS devices, etc., you can also connect them through your mobile phone to get a better experience.

"Generally speaking, Sony

Xperia XZ's system upgrades mainly stay at the user interface level. In terms of user experience, it still continues Sony's usual smoothness. But it's a cliché. Functionality and local optimization are still Sony's weaknesses.

"A brief analysis of triple image sensing technology

The so-called triple image sensing technology is simply the same as Sony Xperia XZ. Built-in image sensor, laser focus sensor and RGBC-IR sensor. Among them, the image sensor is more technically advanced than the previous generation model. The laser focus sensor is used for fast close-range focusing, and the RGBC-IR sensor is the first to appear in the Xperia series of mobile phones, which mainly improves the accuracy of white balance and exposure.

1. "Image sensor

: The full name of the image sensor used on Sony Xperia XZ is the Exmor RS sensor, which is what we often call a stacked sensor. What is different from the past is that The image sensor equipped on Sony Xperia XZ supports predictive focusing technology, which is an upgraded version of PDAF phase focusing and can predict the next movement of the subject on a basic basis to improve the shooting rate.

2 , "Laser focus sensor

: As for laser focus, everyone is already very familiar with it. It is common in flagship mobile phones. The main principle is to emit multiple laser beams to the subject through a laser device and receive the reflected light. The laser calculates the distance between the camera and the subject, allowing for fast focusing. The advantage of laser focusing is not only that it can achieve fast focusing under sufficient light conditions, but also that it can achieve fast focusing in dark light environments, without the constant "bellows" like traditional contrast focusing. However, laser focus also has limitations. Sony officials say that it can only achieve fast focus from 15cm to 100cm, so laser focus is of no use when shooting large outdoor scenes.

3. "RGBC-IR sensor

▲RGB-IR sensor implementation principle

The RGBC-IR sensor is the focus of the Sony Xperia XZ camera upgrade, which is different from the traditional Different from the RGB sensor, the RGBC-IR sensor can additionally record infrared images and colorless pixels, and then adjust the white balance and exposure through algorithms. In other words, through this technology, Sony Xperia XZ can still operate in complex scenes. Restore the color of the subject to the greatest extent.

From the perspective of the triple image sensor principle, the main advantages of the Sony Xperia XZ camera are focusing ability, color performance and white balance control.

"Sony Xperia XZ Camera User Experience

Today's mobile phone manufacturers are imitating Apple in the design of the camera interface, trying to provide users with a faster and simpler camera experience. The Sony Xperia XZ remains unchanged for thousands of years, continuing the operation interface similar to its own SLR camera. Even in the advanced automatic mode, you can still see various complex options in the settings menu in the lower right corner, such as automatically browsing photos and grid lines. , touch to take pictures, etc. Sony still does not provide the filters we often use, and we can only adjust the color temperature or brightness by calling out the menu.

▲Sony Xperia XZ camera interface

Sony’s design is too niche, and it is more pleasing to geek users and influencers.

However, as mobile phones are mass consumer products, the author still hopes that Sony can conduct more research on consumers’ common usage habits, simplify complicated operating steps, and make taking pictures easier. It is also worthy of praise that Sony Xperia XZ calls out the camera very quickly. The actual experience is basically equivalent to the official 0.6 seconds. When the screen is locked, just press the camera button again to open the camera, which can be used in daily life very conveniently. of snap shots.

Another major advantage of Sony cameras is that they have a very rich set of camera applications, with which users can take a variety of creative photos. However, these camera applications are often power-hungry, and they are fine if used occasionally. However, they are prone to serious problems such as heating and power loss when used for a long time.

The comparison pictures did not undergo any post-processing except cropping. Both phones were shot in automatic mode.

Two things need to be explained before comparing.

1. Sony Xperia. The XZ samples were all shot in 23-megapixel mode, while the iPhone 6s Plus has 12 million pixels, so the former has an absolute advantage in resolution, while the latter has faster and more stable image processing and algorithms due to its lower pixels.

2. Judging from the author’s own experience, the Sony Xperia XZ has a clear advantage over the iPhone6s Plus in terms of focusing. In dark light environments or macro shooting, the iPhone6s Plus often suffers from "bellows". Phenomenon, so that a slight shake when taking pictures will cause misfocus or blurred images. Thanks to the application of triple image sensors, this phenomenon almost never occurs on Sony Xperia XZ.

" Sample photos. Comparison:

Outdoor sample comparison (3)

From the above two comparison pictures, we can see that the white balance of Sony Xperia XZ is cooler when shooting outdoor scenes. This is most obvious in the second picture. Compared with the real scene, the iPhone6s Plus sample is closer to the original color at that time. However, the photos taken by Xperia XZ have richer colors and high saturation, which are more pleasing to the user's eyeballs. However, when there is sufficient light outdoors, the iPhone6s Plus is overexposed and the entire picture becomes very pale.

Macro

Comparison of proofs (4)

In terms of macro, the sample performance of Xperia XZ and iPhone6s Plus is comparable. The strengths of the Xperia XZ are that the lens can capture a wider range of scenes, has stronger background blur capabilities, and has better resolution. The advantage of iPhone6s Plus is that the light metering is very stable. After comparing multiple photos, we can find that Apple is more unique and sophisticated in adjusting and controlling various camera parameters.

▲

Backlight sample comparison

Under backlight conditions, iPhone6s Plus performed very calmly. The HDR mode is automatically turned on when taking pictures. Not only can the clouds in the sky be clearly captured, but the colors of the pavilion's eaves can also be well displayed. On the other hand, the Xperia XZ is significantly inferior to the iPhone 6s Plus. Although the camera automatically recognizes that it is under backlight conditions when taking pictures, the imaging effect is still unsatisfactory.

▲Indoor dark light sample comparison

Under indoor dark light, Xperia XZ has the problem we mentioned at the beginning again. Its color performance is a bit too rich. Obviously, Sony is in an artistic style and can pay more attention to the color expression of things. Without comparison, you would think that the photos taken by Sony Xperia are excellent. However, whether it is better to restore the original color of things or try to please the user's eyeballs, the author cannot judge which is better, it still varies from person to person.

▲Outdoor night scene sample (1)

▲

Outdoor night scene sample (2)

Thanks to the excellent inheritance of SLR cameras Gene, the ISO of Sony Xperia XZ's rear camera can soar up to 12800, but judging from the sample, the ISO of 2500 is already incredible, and the entire picture is much brighter than that of iPhone6s Plus. However, an ISO that is too high will also cause the sample noise to soar. In addition, the sky is red in the Xperia XZ sample. I hope Sony will improve this in future software updates.

" Five-axis anti-shake comparison test:

In fact, in addition to the triple image sensor for taking pictures, Sony's five-axis anti-shake is also a major feature. It can adjust the level through algorithms , vertical, rotation, horizontal rotation, and vertical deflection jitter, thus making the recorded picture more stable.

The following video shows the Apple iPhone 6s Plus on the left and the Sony Xperia XZ on the right (both phones are 1080P, shot in 30fps mode)

It is not difficult to see that the performance of the Sony Xperia XZ five-axis anti-shake is amazing when I first started walking, but the difference between the two was not obvious when running. When moving, the picture of Sony Xperia XZ is still quite stable, while the iPhone6s Plus has already shaken very badly. But unfortunately, this five-axis technology can only be used in Sony's own camera. After testing, it does not work when using the live broadcast software. It supports five-axis anti-shake, and of course Sony does not rule out adaptation in the future, but judging from Suo Dafa’s usual practice, this is almost impossible.

"Photo comparison summary:

"Advantages of Sony Xperia XZ:

1. The camera exhales quickly and focuses quickly.

2. The image is sharp and the resolution is high.

3. The color saturation of the sample is high, especially the three colors of red, green and blue.

4. The picture is bright at night.

5. The five-axis anti-shake performance is outstanding. p>

"Disadvantages of Sony Xperia XZ (only for 23 million pixels):

1. The camera interface options are complex and prone to lag.

2. The light metering is not accurate enough, and the brightness and darkness are erratic.

3. The sky turns red at night.

4. The backlight performance is average.

After this experience, the photo button that has always been retained in the Sony Xperia series has won my heart. It feels like taking photos with a compact camera. The photography of Sony mobile phones still gives me a feeling of being technologically advanced but lagging in optimization. The imaging performance in automatic mode is good and bad. If you know something about the camera and know how to adjust the parameters, you can easily take good-looking photos with Sony Xperia XZ.

" Hardware performance test

In terms of hardware performance, Sony Xperia XZ is equipped with Qualcomm Snapdragon 820 processor, equipped with 3GB running memory, 64GB eMMC flash memory, and supports 256GB body storage capacity Extension. Everyone should be quite familiar with the Snapdragon 820 processor. This is Qualcomm’s flagship processor at the beginning of 2016, and it has been widely used in flagship mobile phones of major brands this year.

The Snapdragon 820 chip uses the 64-bit Kryo architecture independently developed by Qualcomm and uses the 14nm FinFET process. The CPU part has four cores with a maximum frequency of 2.15GHz. The GPU uses the independently designed Adreno 530. The overall performance has been significantly improved compared with the previous generation.

In addition to the CPU/GPU, Snapdragon 820 also uses the built-in Hexagon680 DSP. This DSP uses the new Hexagon architecture and integrates HVX (vector extension) and low-power island. Based on the low-power island, sensor information can be processed, and other chips that do not need to work can be completely turned off to avoid wasting power consumption. On the other hand, based on this DSP, photos (videos) can also be dynamically adjusted in real time, such as increasing the brightness in darker parts while keeping the entire brightness of the picture unchanged, which is the so-called LTM technology.

In addition, for mobile phone signals, Snapdragon 820 also uses TruSignal technology. When the posture of holding the phone affects the antenna signal, TruSignal can intelligently turn the secondary antenna in other parts of the phone into the main antenna for use. , maintain call quality and reduce call drop rates; at the same time, dynamically find environmental changes based on signal fluctuations at the edge of the base station, quickly adjust and make up for the deterioration, thereby achieving a significant increase in call quality and effectively reducing the call disconnect rate.

In the actual AnTuTu benchmark test, the Sony Xperia XZ scored 120,751, showing no lag in the face of large-scale 3D mobile games and other applications that consume hardware performance. At present, the main improvement of Qualcomm's latest Snapdragon 821 processor is in the main frequency of the CPU and GPU. The overall performance has been improved, but there will be no obvious difference in actual use. When users choose a mobile phone, they don’t have to worry too much about Snapdragon 820 and Snapdragon 821.

About running memory and flash memory. While major flagships are starting to use 4GB of running memory, the flagship phone Sony Xperia XZ still insists on using 3GB of running memory. Many users may have questions, is 3GB of storage enough? In fact, 3GB of running memory is enough to run the Android system smoothly. Among the minimum requirements for hardware performance of Android 6.0, 3GB is higher than the minimum requirements. However, in China, due to the lack of Google GCM (Google Cloud Messaging) push, major applications (mainly domestic applications) will make their own message notifiers in the background and try their best to keep them awake in the background. Coupled with the mutual wake-up mechanism of domestic applications (common in Baidu, Alibaba, and Tencent software), this has further led to a shortage of executable memory.

So, whether 3GB of running memory is enough depends mainly on the user's usage habits. If you know how to effectively control background application wake-up and persistence, 3GB of running memory is enough. But if you let these software flow and occupy resources in the background, 6GB of memory may not be enough, let alone 4GB. To sum up, the overall hardware performance of Sony Xperia XZ currently seems to be top-notch, ranking in the first echelon.

" Fever test

▲Sony We tested the heating conditions of Sony Xperia XZ. From the results, the heating spots on the front of the fuselage are mainly concentrated under the screen. Although the temperature can reach up to 42.1 degrees, since the heating spots are not on the screen, they will not be affected during use. It feels obviously hot. The heating on the back of the fuselage is very even, and the temperature of the entire metal plate is not much different. This is mainly due to the fact that the magnesium aluminum lithium alloy used in Sony Xperia XZ has good thermal conductivity and can evenly distribute the heat. Faster heat dissipation.

" Personal experience and summary

Meticulousness is the perfect way to describe the design of Sony Xperia XZ.

Whether it is the control of black edges, the protection of the screen glass or the principle of not protruding the camera, I am deeply impressed. Stereo speakers, triple image sensors, IP68 waterproof, and other features are its plus points. The only thing I regret is the system. Although the UI design of the system is very exquisite and attractive, it cannot be compared with deeply customized systems such as MIUI and Flyme in terms of functionality and localization. In addition, due to the phenomenon of background chain wake-up in domestic applications, mobile phones often consume abnormal power. For people like me who often use mobile phones to browse Weibo and read news, it is difficult to guarantee the Sony Xperia XZ

One day of use. Although turning on STAMINA mode can significantly increase battery life, it will seriously limit the performance of the phone, cause operation lags, and affect the mood of use.

At present, domestic Sony Mobile basically only relies on hardware to make profits, so it cannot squeeze the price to the level of domestic mobile phones. Again, most people who are really willing to buy Sony mobile phones will not focus on the shortcomings of software and hardware. Because although it is a flagship, it neither has the strongest hardware performance nor the best software experience. But exquisite industrial design and distinctive selling points are often the most attractive, and they are also what is currently lacking in the mobile phone market. Many features on Sony Xperia XZ, such as triple image sensors, five-axis anti-shake, IP68 dustproof and waterproof, etc., are also not available in many mobile phones.

It is commendable that the heat generation of Sony Xperia XZ has been significantly improved compared to the Xperia Z3/Z5/Z5 Premium Edition. The system's built-in software has also been streamlined, leaving only Baidu Maps, mobile Baidu and Sina Weibo, and most of them can be disabled directly.

For the domestic mobile phone market where a hundred flowers are blooming, Sony mobile phones are still full of huge challenges. Apple and Samsung firmly control the high-end mobile phone market, and the flagship products of LeTV, Xiaomi, OnePlus and other manufacturers continue to lower the price limit. Sony

Xperia XZ’s price positioning of up to 4,999 yuan really scares away mass consumers. Under the huge cost of R&D, promotion, operation, etc., Sony has to use its products to win the hearts of more users and continue to achieve brand premiums. The market test has become more severe. But no matter what, we cannot deny that Sony Xperia XZ is indeed a flagship phone with very strong overall quality.
