Using design to promote product transformation Sony Xperia XZ evaluation

IT 168 Evaluation Some time ago, Sony CEO Kazuo Hirai said in an interview that Sony would not quit the smartphone market and hoped to become a leader in the future. This response positively dispelled the outside world's crisis remarks about Sony Mobile. Judging from Sony's recent financial report, after some adjustments of 20 15, Sony's overall business finally turned a profit. In the first quarter of 20 16, Sony's mobile business also achieved profitability. Although the net profit is only $04 million, it is not easy. Achieving profitability is closely related to Sony Mobile actively adjusting its market strategy, not blindly expanding its scale, and seeking profit space as a whole.

At the product level, Sony ended the Xperia Z series mobile phone that has been iterated for three years with the Xperia Z5. Although many people feel sorry for the Z series products, Sony Mobile has to face the breakthrough and change of demand in the fierce competition environment. At the MWC at the beginning of this year, the launch of Xperia X, Xperia X Performance and Xperia XA was a good start, which played a connecting role in the transition from Xperia Z to Xperia X. The Xperia XZ released at this year's IFA was a milestone. The transformation has also been highly anticipated by 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 Sony is good at industrial design and hardware black technology, and these two specialties are just displayed on Xperia XZ. Compared with the fully balanced design of the previous Xperia Z series, Xperia XZ adopts a brand-new design language "unified design". The fuselage material is changed from double-sided glass to all-metal fuselage (the back cover is made of Mg-Al-Li alloy). In addition, 2.5D glass, ultra-narrow frame and other design elements are added, which is more easily accepted by the public, thus changing the previous problem of middle frame. In other words, from Xperia XZ, we can see the design innovation brought by Sony to the industry, and we can also find the design choices made by Sony under the trade-off.

Needless to say, the Sony Xperia XZ uses a 5.2-inch 1080P display, a Qualcomm Snapdragon 820 processor platform, 3GB of running memory, 64GB of body storage space, a 23-megapixel main camera and a 2900mAh battery. Sony puts 3GB of running memory.

The flagship mobile phone such as Xperia XZ is a bit of an eyesore, which is what most consumers vomit, but if you really want to buy this mobile phone, you probably won't pay attention to these hardware parameters. After all, the real charm of Sony mobile phone is not in the hardware parameters. In addition, it is a great pity that the Bank of China does not support Netcom.

Sony Xperia XZ's main selling points this time are triple image sensing technology and five-axis image stabilization (electronic image stabilization). The so-called triple image sensing technology is simply that Sony Xperia XZ is equipped with RGBC-IR sensor in addition to the built-in image sensor and laser focus sensor, so as to obtain more accurate white balance and exposure value. Regarding the specific imaging of its camera, we put it behind the camera part to elaborate in detail.

In terms of appearance and industrial design, Sony has always had its own unique insistence. From Sony's products, we can clearly see the strong Japanese flavor: fresh, simple and square. These iconic design elements are also fully reflected on Sony Xperia XZ. Next, let's briefly interpret the design of Sony Xperia XZ.

On the front of the fuselage, the overall shape of Sony Xperia XZ is square and tough, with stereo dual speakers at both ends. The machine adopts the design of 2.5D glass on the side, and with the rounded radian design of the fuselage side, it ensures a good grip on the fuselage side. Different from the common 2.5D glass design, Sony Xperia XZ only made a 2.5D transition on the left and right sides of the screen glass, and the top and bottom of the front of the fuselage were specially treated at the junction of the frame and the glass.

As you can see, the top and bottom borders of this phone are slightly higher than the screen glass, just like being embedded in a metal body. The design that the frame is higher than the screen glass is very common in Sony's previous mobile phones. The advantage of this is that the glass can be prevented from directly touching the ground when the mobile phone falls, which reduces the risk of broken screen, but it also sacrifices the sense of grip. This time, under the premise of ensuring safety, Sony Xperia XZ optimized the grip and achieved both aesthetic feelings.

On the top of the front of the fuselage, besides the receiver, sensor and front camera of the speaker, there are breathing light and NFC chip (located between breathing light and front camera). In other words, when using NFC-related functions, try to make this part close to the sensing area. On the other hand, Sony Xperia XZ currently only supports Google Wallet, and it can't be used for payment for the time being. The purpose I can think of is only to recharge the bus card and read the information of a specific NFC chip.

Regarding the top area of mobile phone fuselage, we can see that many domestic mobile phone manufacturers have adopted symmetrical design, and arranged these components at the top reasonably to make them look more concise. The top layout of Sony Xperia XZ is a bit messy and unsightly. In particular, printing the "Sony" logo in this area will lose some sense of design.

On the back of the fuselage, the body material used by Sony Xperia XZ is different from ordinary mobile phones, and it is magnesium-aluminum-lithium alloy. This material is not only light and thin, but also has better stability and thermal conductivity. After sandblasting polishing, its surface has high metallic luster and is not easy to be contaminated with fingerprints. Because it is an all-metal body design, there is an antenna overflow at the bottom of Sony Xperia, and the surface is covered with a plastic cover. This treatment is not common in high-end mobile phones, mainly because it is difficult for metal and plastic materials to be exactly the same in color. However, we can see that Sony handled it very properly on the mobile phone Xperia XZ, and the color difference between the two materials is not obvious, which still has a high degree of integration.

In the camera part, the Sony Xperia XZ uses a 23-megapixel main camera, and the official said that it only takes 0.6 seconds for the camera to wake up. And it has supported the high ISO of 12800 for a long time, but the lack of optical image stabilization is still regrettable, but video recording supports 5-axis electronic image stabilization. However, the highlight of Sony Xperia XZ in camera is the use of triple image sensing technology, namely: image sensor, laser autofocus sensor and RGBC- infrared sensor. Among them, RGBC infrared sensor is mainly used to improve white balance and exposure accuracy. In the simple process of getting started, the white balance performance of Sony Xperia XZ main camera really makes people shine, and even the iPhone, which is known for its "scary" white balance, has to admit failure.

Sony is one of the few mobile phone brands that insist on using the side fingerprint identification buttons, and the reason why Sony does not adopt the front or back fingerprint identification scheme is largely due to the consideration of the beauty and integrity of the fuselage. Because the inside space is small and the outside fingerprint identification area is small, the side fingerprint identification scheme actually has no advantage. However, after continuous optimization, the fingerprint identification experience of Sony Xperia XZ has been very good in speed and accuracy, which can be said to be "secondary unlocking".

However, it is still a pity that the software support of fingerprint identification is not very good. In the system, it can only be used to unlock the screen at present. Sony Xperia XZ does not have the functions of album encryption and folder encryption that are common in domestic mobile phones. At present, only the fingerprint login that can be used in the handheld banking client of China Merchants Bank is found, and the fingerprint payment of Alipay and WeChat is not supported.

Finally, let's look at the bottom of the fuselage. Sony Xperia XZ adopts an integrated middle frame design, and a groove (same top) is machined by CNC at the bottom of the fuselage. The texture of the bottom is actually different from the middle frame of the fuselage, smoother and brighter. There is no official explanation for this part, but in terms of perception, this part should be embedded with a glass. Exquisite details. Compared with the traditional Micro USB interface, the USB Type C interface used by Sony Xperia XZ has obvious advantages, supporting larger charging current and faster data transmission speed. It's very popular now.

The above is an interpretation of the appearance of Sony Xperia XZ. Continues Sony's consistent Japanese style, simple and square. These improvements, such as the 2.5D curved glass on the front of the fuselage and the rounded middle frame of the fuselage, did not make it lose the inheritance of family design, but made some fruitful optimizations in the grip, which is really hard to get. The excellent workmanship of Sony Xperia XZ can make a large number of domestic mobile phones far behind. Some domestic brands that have always claimed to be "artisan spirit" are really embarrassed in front of Sony Xperia XZ?

For most international manufacturers, the localization optimization of China market has always been a headache. Because Google service can't be used in China, foreign mobile phone manufacturers need to customize a set of services for domestic users to meet the needs of domestic users. Apple and Samsung are top international brands in this localization, but there are still some unaccustomed places in details. Sony Mobile's strategy on the mobile phone system has always been to adhere to the principle of simplicity, conciseness and fluency, and to follow the operating logic of native Android, which leads to the optimization of Sony's mobile phone software far from the domestic customization system.

The system of Sony Xperia XZ is modified and designed based on Android version 6.0.1,and it is expected to be upgraded to Android version 7.0 in the next month or two. The advantage of following the native system light customization is that the basic functions can be stable and smooth, and the iteration speed of the version can keep up with the pace of Android in time. The problem is that localization services with convenient details are difficult to satisfy users, and users need to download third-party software to supplement their functions. However, there are problems in the domestic environment. First, the phenomenon of domestic application background chain startup is serious, which will increase power consumption; Second, there are many advertisements for domestic tool software, and the experience is unfriendly. Therefore, Gensonnie's mobile phone system has fallen into a very embarrassing situation in the domestic market.

Having said that, from the author's current experience, installing green daemon software can improve the problem of application background startup, and it will be better if combined with ROOT (ROOT is not recommended by ordinary users, and the warranty service may be lost after ROOT). However, this undoubtedly increases the learning cost of ordinary users. I hope this problem can be taken seriously by Sony Mobile and improved in the future Android 7.0 upgrade.

Sony Xperia XZ

Basic frame interface

When I first started using Sony Xperia XZ, I found its user interface very pleasing. The design is concise and exquisite, and the color is changeable, which conforms to the aesthetics of young people. It has a positive role in promoting brand tonality, and also conforms to the consistent style of Dafa. After a period of use, Sony's interface design also makes me feel that it is not easy to cause aesthetic fatigue. Especially the music playing interface, it is difficult to find out who can design a more beautiful Bisogni.

Sony Xperia XZ comes with its own software interface.

Sony slightly optimized the calendar for domestic regions. You can display the lunar calendar and mark holidays, but the subscription function is not supported. If your TV supports video &; The TV side view function can load the latest TV program information and program preview on the mobile phone. At the same time, you can mark the programs you want to watch or set reminders. In addition, the mobile phone can also be used as the remote control of TV, which is very convenient.

Software technical support of Sony Xperia XZ

Sony Xperia XZ's accomplishments in audio and display are still commendable. Compressed audio or color ordinary pictures are placed in Sony.

In Xperia XZ, you can get better performance, so it is good to add a Dafa here. In addition, if you have other Sony products, such as cameras, televisions, PS devices, etc. You can also contact them through your mobile phone to get a better experience.

"In general, Sony

The system upgrade of Xperia XZ mainly stays at the user interface level. In terms of user experience, it still continues Sony's consistent fluency. But old-fashioned functions and local optimization are still Sony's weakness.

"Analysis of triple image sensing technology.

The so-called triple image sensing technology is simply that Sony Xperia XZ has built-in image sensor, laser focus sensor and RGBC infrared sensor. Among them, the image sensor is more advanced in technology than the previous model, the laser focusing sensor is used for fast close-range focusing, and the RGBC- infrared sensor first appeared in the Xperia series of mobile phones, mainly improving the accuracy of white balance and exposure.

1, "image sensor

The full name of the image sensor used on Sony Xperia XZ is Exmor RS sensor, which is often called stacked sensor. Different from the past, the image sensor equipped with Sony Xperia XZ supports predictive focusing technology, which is an upgraded version of PDAF phase focusing, and can predict the next move of the subject on the original basis, thus improving the shooting speed.

2. "Laser focusing sensor"

As for laser focusing, we are already very familiar with it. Common in flagship phones. The main principle is that a laser device emits multiple laser beams to the subject, and the distance between the camera and the subject is calculated by receiving the reflected laser beams, thus realizing fast focusing. The advantage of laser focusing is that it can not only achieve fast focusing in sufficient light, but also won't "pull the bellows" like traditional contrast focusing in dark environment. However, laser focusing also has limitations. Sony officially said that it can only achieve fast focusing of 15cm- 100cm, so laser focusing is useless when shooting outdoor scenes.

3. "RGBC-infrared sensor

▲ Realization principle of ▲RGB-IR sensor

RGBC infrared sensor is the key to upgrade Sony Xperia XZ camera. Different from the traditional RGB sensors, RGB infrared sensors can record extra 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 restore the color of the subject itself to the greatest extent even in scenes with complex environment.

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

"Sony Xperia XZ camera experience

Nowadays, mobile phone manufacturers are imitating Apple in the design of camera interface, trying to provide users with a faster and simpler camera experience. Sony Xperia XZ remains unchanged for ten thousand years, continuing the operation interface similar to its own SLR camera. Even in the advanced automatic mode, you can still see various complicated options in the settings menu in the lower right corner, such as automatically browsing photos, gridlines, touching photos and so on. The filter we often use is still not provided by Sony, so we can only bring up the menu to adjust the color temperature or brightness.

▲ Sony Xperia XZ camera interface

Sony's design is too biased towards the minority, which is more pleasing to geek users and affects enthusiasts. However, as a mass consumer product, I still hope that Sony can investigate consumers' general usage habits, simplify complicated operation steps and make taking photos easier. In addition, it is commendable that Sony Xperia XZ can transfer the camera very quickly, and the actual experience is basically equivalent to the official 0.6 seconds. When the screen is locked, you can directly press the camera button again to turn on the camera, which is very convenient for capturing pictures in life.

Another advantage of Sony camera is that it has a very rich camera application, and users can take all kinds of creative photos with it. However, these camera applications are often large power consumers, and it is ok to use them occasionally. Long-term use is prone to serious problems such as fever and power failure.

"Comparative analysis of photo proof.

In the process of taking photos, in order to more intuitively reflect the image of Sony Xperia XZ, I compared it with my iPhone 6s Plus. In addition to the post-processing of the released contrast image, both phones were shot in automatic mode.

There are two things to explain before comparing.

1 and the proofs of Sony Xperia XZ are all shot in the mode of 23 million pixels, and the pixels of iPhone6s Plus are12 million, so the former has an absolute advantage in resolution, while the latter is faster and more stable in image processing and algorithm because of its low pixels.

2. From the author's own experience, Sony Xperia XZ has obvious advantages over iPhone6s Plus in focusing. In the dark environment or macro shooting, iPhone6s Plus often appears the phenomenon of "bellows pulling", so that a slight jitter when taking pictures will lead to inaccurate focusing or blurred imaging. Thanks to the application of triple image sensor, Sony Xperia XZ has hardly seen this phenomenon.

"Proof comparison:

Comparison of outdoor proofs (3)

As can be seen from the above two comparison pictures, the white balance of Sony Xperia XZ is cold when shooting outdoor scenes. This is most obvious in the second picture. Compared with the real scene, the proof of iPhone6s Plus is closer to the original color at that time. However, the photos taken by Xperia XZ are richer in color, more saturated and more user-friendly. However, in the case of sufficient outdoor light, the iPhone6s Plus was overexposed and the whole picture became very pale.

microspur

Comparison of evidence (4)

In terms of macro, both Xperia XZ and iPhone6s Plus have similar proofs. The advantage of Xperia XZ is that the lens can shoot a wider range of scenes, and the background blur ability is stronger and the resolution is better. The advantage of iPhone6s Plus is that metering is very stable. By comparing several photos, we can find that Apple is more original and meticulous in adjusting camera parameters.

▲

Contrast of backlight proofs

Under the backlight condition, the iPhone6s Plus is very calm. When taking pictures, HDR mode will be automatically turned on, which can not only clearly capture the clouds in the sky, but also display the color of the pavilion eaves well. On the other hand, Xperia XZ is obviously worse than iPhone6s Plus. Although the camera will automatically recognize that it is in the backlight state when taking pictures, the imaging effect is still not satisfactory.

▲ Comparison of indoor dark proofs

Under the darkroom, Xperia XZ has the problem we mentioned at the beginning again, and the color performance is a bit too strong. Obviously Sony is following the artistic style, and can pay more attention to the color expression of things. If you don't compare, you will feel that the photos taken by Sony Xperia are excellent. But whether to restore the original color of things or try to please users' eyes is good, I can't evaluate which is better or worse, or it varies from person to person.

▲ Outdoor night view proofs (1)

▲

Outdoor night scene proofs (2)

Thanks to inheriting the excellent genes of SLR cameras, the ISO of Sony Xperia XZ's rear camera can soar to 12800 at the highest, but from the proofs, the ISO of 2500 is already terrible, and the whole picture is much brighter than that of iPhone6s Plus. However, too high ISO will also cause the noise of proofs to soar. In addition, the sky is red in the proofs of Xperia XZ, and I hope Sony will improve it 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 jitter of horizontal, vertical, rotation, horizontal rotation and vertical deflection by algorithm, thus making the recorded picture more stable.

The following video shows Apple iPhone6s Plus on the left and Sony Xperia XZ on the right (both phones are shot in 1080P and 30fps modes).

It is not difficult to see that the realization of Sony Xperia XZ five-axis anti-shake is amazing. At the beginning, the gap between the two was not obvious, but the picture of Sony Xperia XZ was relatively stable when running, while iPhone6s Plus kept shaking badly. But unfortunately, this five-axis technology can only be used on Sony's own camera. After testing, five-axis anti-shake is not supported when using live broadcast software. Of course, Sony's later adaptation is not ruled out. But judging from the consistent practice of Suodafa, it is almost impossible.

"Photo comparison summary:

"Advantages of Sony Xperia XZ:

1, the camera exhales quickly and focuses quickly.

2. Clear imaging and high resolution.

3. The proofs have high color saturation, especially red, green and blue.

4. The proofs are bright at night.

5, five-axis anti-shake performance is bright.

"Disadvantages of Sony Xperia XZ (only 23 megapixels):

1, the camera interface options are complex and easy to get stuck.

2. The metering is not accurate enough and the brightness is erratic.

The sky turns red at night.

4. The backlight performance is average.

After this experience, the camera keys retained by Sony Xperia series won my heart, and there is a feeling of taking pictures with a card camera. The photos of Sony mobile phone still give me a feeling that the technology is leading and the optimization is lagging behind. In automatic mode, the imaging performance is good or bad. If you know something about cameras and know how to adjust parameters, it is easy to take good-looking photos with Sony Xperia XZ.

"hardware performance test

In terms of hardware performance, Sony Xperia XZ is equipped with Qualcomm Xiaolong 820 processor, 3GB of running memory, 64 GB of EMMC flash memory, and supports 256GB of body storage capacity expansion. Everyone should be quite familiar with the Xiaolong 820 processor, which was the flagship processor of Qualcomm in 20 16, and was widely used in flagship mobile phones of major brands this year.

Xiaolong 820 chip adopts 64-bit Kryo architecture independently developed by Qualcomm and adopts 14nm FinFET process. The CPU is partially quad-core, up to 2. 15GHz. GPU adopts Adreno 530 designed by ourselves. The comprehensive performance has been significantly improved compared with the previous generation.

In addition to CPU/GPU, Xiaolong 820 also has built-in Hexagon680 DSP, which adopts a brand-new Hexagon architecture and integrates HVX (Vector Expansion) and low power island. Based on the low power island, the sensor information can be processed, and other chips that don't need to work can be completely turned off to avoid wasting power. On the other hand, based on this DSP, photos (videos) can be dynamically adjusted in real time, such as improving the brightness in the dark, while the overall brightness of the picture remains unchanged, which is the so-called LTM technology.

In addition, regarding the cell phone signal, the Xiaolong 820 also adopts TruSignal technology. When the posture of the hand-held mobile phone affects the antenna signal, TruSignal can intelligently turn the auxiliary antenna in other parts of the mobile phone into the main antenna, thus maintaining the call quality and reducing the dropped call rate. At the same time, according to the fluctuation of the edge signal of the base station, the environmental changes are dynamically found, and the deterioration results are quickly adjusted and compensated, so that the call quality is greatly improved and the dropped call rate is effectively reduced.

In the actual Ann Bunny running test, Sony Xperia XZ scored 12075 1, and there will be no delay in the face of large-scale 3D mobile games and other applications that consume hardware performance. At present, the main improvement of the latest Snapdragon 82 1 processor in Qualcomm lies in the main frequency of CPU and GPU, and the overall performance has been improved, but there will be no obvious difference in actual use. When choosing a mobile phone, users need not worry too much about Xiaolong 820 and Snapdragon 82 1.

About running memory and flash memory. Sony Xperia XZ, the flagship mobile phone, still insists on using 3GB of running memory, when the major flagships have jumped out of 4GB of running memory. Many users may have questions, is 3GB enough? In fact, 3GB of running memory is enough to run the Android system smoothly, which is higher than the minimum requirements for hardware performance of Android 6.0. 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 to stay awake as much as possible. Coupled with the domestic application of mutual wake-up mechanism (common in Baidu software, Ali software, Tencent software), further leading to insufficient runnable memory.

So whether 3GB of running memory is enough depends mainly on the user's usage habits. If you know how to effectively control the wake-up and stay of background applications, 3GB of running memory is enough. However, if these softwares are left to their own devices, they will always occupy resources in the background, not to mention that 4GB or 6GB of memory may not be enough. To sum up, the overall hardware performance of Sony Xperia XZ seems to be top-notch and in the first echelon.

"A fever test.

▲ Sony Xperia XZ heat test under high load.

We have tested the fever of Sony Xperia XZ when the mobile phone performance is fully open. From the results, the hot spots on the front of the fuselage are mainly concentrated at the bottom of the screen. Although the highest temperature can reach 42. 1 degree, because the hot spot is not on the screen, you will not feel obvious heat when using it. The heating on the back of the fuselage is very uniform, and the temperature of the whole metal plate is not much different. This is mainly because the magnesium-aluminum-lithium alloy used in Sony Xperia XZ has good thermal conductivity, which can average the heat and dissipate heat faster.

"Personal experience and summary.

It's perfect to describe the design of Sony Xperia XZ in detail. Whether it is the control of the black edge, the protection of the screen glass, or the principle that the camera is not prominent, it has won my heart. Stereo speaker, triple image sensor, IP68 waterproof and other functions are its advantages. The only thing that makes me regret is its system. Although the UI design of the system is exquisite and attractive, it can't be compared with deep customization systems such as MIUI and Flyme in terms of functionality and localization. In addition, due to the background chain wake-up phenomenon of domestic applications, mobile phones often consume abnormal power. For people like me who often use my mobile phone to brush Weibo to watch news, Sony Xperia XZ is hard to guarantee.

One-day use. Although starting the stamina mode can obviously increase the battery life, it will seriously limit the performance of the mobile phone, causing the operation to be stuck and affecting the mood of use.

At present, Sony Mobile in China basically relies on hardware to make profits, so it can't squeeze the price to the level of domestic mobile phones. Again, most people who really want to buy Sony mobile phones will not focus on the lack of software and hardware. Because although it is the flagship, it is neither the strongest hardware performance nor the best software experience. However, exquisite industrial design and distinctive selling points are often the most attractive and lacking in the current mobile phone market. Many features of Sony Xperia XZ, such as triple image sensor, five-axis anti-shake, IP68 dustproof and waterproof, are also not available in many mobile phones.

It is commendable that the fever of Sony Xperia XZ is obviously improved compared with the exclusive version of Xperia Z3+/Z5/Z5. The built-in software of the system has also been streamlined, leaving only Baidu Map, mobile phone Baidu and Sina Weibo, most of which can be directly disabled.

For the domestic mobile phone market, Sony mobile phone is still full of great challenges. Apple and Samsung firmly control the high-end mobile phone market, and the flagship products of manufacturers such as LeTV, Xiaomi and Yijia keep lowering the price floor. Sony

The price positioning of Xperia XZ is as high as 4999 yuan, which really makes mass consumers daunting. Under the huge cost of R&D, promotion and operation, the market test of how Sony can win the hearts of more users with its products and realize the brand premium continuously is even more severe. But in any case, we can't deny that Sony Xperia XZ is indeed a flagship mobile phone with very strong comprehensive quality.
