The image of Xperia Z series has gradually entered the hearts of people with Sony's iconic double-sided glass, elegant power key design and elegant color matching. The Xperia Z series, launched under the slogan of One Sony, also bears the ambition of Sony's revival. And how does Xperia Z2, which has more functions and is more powerful in heart, manifest itself?

The Xperia Z series flagship model is now the third generation. In terms of configuration, it basically follows the market trend, with stronger, lighter and thinner performance. Frankly speaking, Sony Xperia Z series flagship is not the most exciting model with the strongest configuration on the market, and the configuration is not the focus in the evolution of each generation. The evolution of Sony Xperia Z's three flagship models, I prefer to think, is the carving and release of details.

The appearance design of the customized Xperia Z2 for operators has changed greatly, and there are slight differences in the system UI and related software. In this paper, the model D6503 is used as the standard for corresponding evaluation, that is to say, the international version.

Appearance design:

In the general direction, Xperia Z2 still continues Sony's OmniBalance full balance design. With the help of double-sided glass and metal frame, it still has a strong Japanese simple style. Compared with Xperia Z1, Xperia Z2 has little difference in three dimensions and shape, so it is urgent to identify.

Of course, the biggest improvement of Xperia Z2 is the screen. After using the IPS screen, we can all say goodbye to the much criticized visual angle and whitening problem. In addition, the screen of Xperia Z2 also adds a technology called Live Color, which makes the color more vivid and pleasing to the eye. Of course, it should be mentioned that Xperia Z2 cancels the previous explosion-proof membrane. First, it avoids the impact on the screen display, and second, it has no annoying friction scratches.

Xperia Z2 is Sony's first smartphone that uses dual speakers. The two speakers are on the top and bottom of the front of the screen. The top speaker is integrated with the indicator light, which is larger than Xperia Z1.

Compared with HTC's BoomSound, the dual speakers used by Xperia Z2 are much more reserved in terms of volume decibels. Of course, the basic stereo effect can be restored. Compared with Xperia Z1, the dual speakers of Xperia Z2 are also completely new, not only with higher volume, but also with better effect.

Microphone with three point openings at the bottom. The rope hole remains as a Japanese style.

Xperia Z2 continues the three proofing features of Sony, and still designs a corresponding waterproof cover, of course, the magnetic charging interface is also retained. The physical keys are still the iconic power key, volume key and shutter key. Compared with Xperia Z1, the physical keys of Xperia Z2 are more robust and have a stronger sense of confirmation.

Xperia Z2 adopts an integrated aluminum middle frame, which has antenna function at the same time, and has made corresponding signal optimization. Xperia Z2 uses the insert molding technology. In fact, it injects the carbon brazing dimension into the metal frame, and then carries out the corresponding cutting and polishing. It has a more solid feel. Compared with the clear layers and gaps on the Xperia Z1 frame, the Xperia Z2 frame has a more integrated feel. Of course, the gaps are no longer there, and the visual effect is better.

The back of Xperia Z2 is still a familiar mirror glass, and the explosion-proof membrane is cancelled to make the texture more obvious. In terms of color, Xperia Z1 is blue with purple, and Xperia Z2 is purple with blue, and there are quite small glitter particles. In contrast, Xperia Z2 is more colorful.

The screen size of Xperia Z2 is 5.2 inches, and the three dimensions are 146.8 * 73.3 * 8.2mm. Compared with the 5-inch 144 * 74 * 8.5mm screen size of Xperia Z1, it is thinner and thinner. The new border technology, larger screen size and more slender three circumference make Xperia Z2 slightly increase the proportion of border and screen, and improve the appearance compared with Xperia Z1.

In terms of single hand operation, due to the same reason of being thin and long, Xperia Z2 has a little room for improvement compared with Xperia Z1. It is also lighter and thinner, making it easier to hold it for a long time than Xperia Z1.

Screen effect:

In fact, the most important improvement of Xperia Z2 lies in the screen. When Xperia Z and Xperia Z1 are used, the visual angle and whitening situation are swept away on Xperia Z2. Xperia Z2 not only uses the IPS screen, but also adds a variety of technologies. For example, the OptiContrast Panel on the hardware actually removes the air layer of the panel and reduces light reflection. There are TRILUMINOS Display and X-Reality for mobile display processors, as well as Any Pencil technology.

Of course, the more important thing is that the Live Color LED technology, which was first used in Xperia Z2, actually uses red and green phosphors to replace the original yellow phosphors to obtain a wider color gamut. In the actual test, the color saturation of Xperia Z2 is also slightly saturated compared with the previous one. The red color is brighter, but there is no obvious feeling.

(In a non full dark environment, all ambient light is reflected through the Xperia Z2 glass panel, and there is no actual visual effect.)

System UI:

Compared with the flat UI style of other international manufacturers, Sony did not follow, but continued its Japanese style. At present, most Sony Xperia machines have upgraded the Xperia UI based on Android 4.4.2, while Xperia Z2 still does, only adding a few hardware functions and temporarily exclusive functions. Therefore, this article only explains this part, and others can be referred to《 The strongest small size Sony Xperia Z1 Compact experience evaluation 》System part.

The task manager adds the "Close All" button, but cannot lock the program separately. Compared with the domestic ROM/OS, it is not flexible enough to use it.

Sony injects some technologies from various departments into Xperia Z2, such as relevant accessory support and software support. In terms of hardware, the Xperia Z2 headphone jack is changed from 3 pin to 5 pin compared with the common one. It supports your own noise reduction headphones and stereo microphones. With hardware support, Sony Xperia Z2 is also the first mobile phone in the world to support digital sound effect noise reduction function.

And Xperia Z2 can use the DAC function of Sony PHA-2 through the mirco USB interface, and enjoy Sony's Hi Res sound effect, making the sound effect better.

In the display, Xperia Z2 has many exclusive functions, such as intelligent backlight control, click wake-up and glove mode. It is worth noting that these three functions are supported by hardware, so even through software updates, Xperia Z1 and other machines cannot achieve them.

Of course, these three functions have been widely used in other brands of machines, so there is not much to show off. The success rate of click wake-up of Xperia Z2 is relatively good. There are corresponding prompts when opening the glove mode, and the overall experience is relatively good.

Sony Xperia Z2 uses the IPS screen, while the acclaimed white balance adjustment still exists. Of course, what makes people complain is that from the use of several Xperia Z1, Xperia Z Ultra and Xperia Z1 Compact machines, the original factory screen tuning is more accurate. But because of the system update, the screen becomes very warm after adding white balance adjustment. For ordinary consumers, such a change is really a bit of a turnabout, and the effect of the white balance adjustment is also very worrying.

If I say that the most surprising thing about Xperia Z2 is not the IPS screen effect or the detailed frame, but its pretty good endurance. The STAMINA mode must be mentioned to maintain the endurance. Compared with other models, Xperia Z2's STAMINI mode divides extended standby into two types. In fact, it reduces hardware performance and power consumption when you open the screen, and pauses operation when you close the screen. The specific use effect and the endurance of Xperia Z2 are described below.

Shooting ability:

Xperia Z2 is the same as Xperia Z1, using the same 1/2.3 inch sensor and 20.7 million pixel G lens, and the camera module is the same. But Xperia Z2 uses a new BIONZ image processor, and with the update and optimization of the system software, the image quality is also improved compared with Xperia Z1. On the shooting interface, Xperia Z2 has certainly not changed much. The only thing that is noticeable is 4K video support.

Both Xperia Z2 and Xperia Z1 use digital anti shake technology, that is, Sony's own SteadyShot, which supports three-way correction and reduces hand-held vibration. In actual use, you can obviously feel the changes in focal length and wide-angle. In fact, SteadyShot relies on high pixel sensors to have more correction space. Generally speaking, StesadyShot achieves shockproof effect through tailoring, and it is really easy to use in practice.

(It is still the standard step of showering girls) Sony Xperia Z2 still uses a 2.2 million pixel camera, which is far from the 5 million pixel take-off of Yishui, a domestic mobile phone. However, from the perspective of girls' comparative use, front camera pixels are not their main concern. For girls, the most important thing is to shoot well and not fake. Of course, Xperia Z2 has skin beautifying effect, and it also converges in beautification degree, which is highly praised.

In terms of macro resolution, Xperia Z2 performs very well, recently focusing at about 8cm.

100% size screenshot, you can feel it a little.

In daily light, Xperia Z2 performs very well in color reproduction and white balance. The background illusion effect brought by F/2.0 large aperture is also very impressive. It should be noted that due to the wide angle of Xperia Z2, there will be some deformation at the edge.

There are some noises in the indoor environment. Fortunately, the noise of Xperia Z2 is small, which does not affect the appearance.

At night, Xperia Z2 has improved a lot compared with Xperia Z1, which was barely clear at the beginning and had a lot of noise. Of course, it is inevitable that the sense of smearing is more obvious, and the edge analysis is quite good.

In general, Xperia Z2 has been improved from powerless to slightly surprising compared with the initial use of 20.7 million pixel G lens by Xperia Z1. Of course, Xperia Z2 can also expand the shooting mode of different functions by installing different applications. For example, the commonly used 120fps video, that is, the slow motion video function, will be expanded more and more in the future.

Sony's enhanced automatic shooting mode, also known as the golden camera. Its original intention was to automatically identify the most suitable shooting mode for the current, but the initial effect was generally or even bad, mainly because the motion mode was quite easy to identify. Under Xperia Z2, this problem has been corrected a lot. The gold camera has really played its actual function.

Thanks to the large size sensor and large aperture, Xperia Z2 is very cool in the high sensitivity night scene. As shown in the figure above, if the M file is used, both the viewfinder and the actual sample sheet are black. If the golden camera is used to automatically identify them as candlelight mode, the viewfinder is black, and the actual sample sheet can display the corresponding objects. Although the iso of the sample has gone to 6400, the picture quality is also very tragic, but it is much better than the black.

Performance and endurance:

Xperia Z2 is equipped with a 2.2GHz MSM8974AB processor and 3G RAM, which is still the flagship model in terms of hardware configuration. But in the actual performance, it did not perform very well. In the theoretical run, the performance is basically the same as that of Xperia Z1, and there is a certain gap compared with the flagship model in the same period.

In the actual game test, Xperia Z2 is also a little sad. When running Wild Speed Racing 8, the frame number is kept at 30fps for most of the time, but the occasional frame drop still makes me feel uncomfortable, although it does not affect the smoothness of the game.

In terms of heat dissipation, Xperia Z2 is thinner than Xperia Z1, and the temperature rises faster under the three proofing seal, but the overall temperature is only about 42 ° C, which is very obvious compared with the 47 ° C of Xperai Z1. The metal frame is only slightly hot when it heats up, which will not affect the holding feeling.

As the main machine, Xperia Z2 enables Bluetooth and Unicom 3G networks from 8:00 a.m. to 8:00 p.m., and keeps wifi on for more than 12 hours. The most surprising thing about Xperia Z2 is its endurance. With 3200nAh battery and STAMINA mode, Xperia Z2 can be used heavily without charging in one day according to my usage habits.

Of course, STAMINA mode is mainly aimed at power saving when the screen is turned off. If the screen is always turned on, the endurance will not be too impressive. Of course, if you enable extended use, you can save power, but the specific choice depends on your personal use.

Other matters:

Continuing the fine tradition of Sony, Xperia Z2 is still the IP58 three prevention level. The waterproof cover is further reduced to 3, and the magnetic charging interface is still reserved to improve the durability. Of course, we need to complain that in different regions and versions of Xperia Z2, the magnetic charging base is not standard. In addition, there are slight changes in the border and overall design of the customized version of domestic operators, and there are some compatibility problems in some protective accessories.

Xperia Z2 uses a new integrated molding technology on the border, so there is no border gap on Xperia Z1, and the visual effect is better. But the same as or more serious than Xperia Z1, the scratch marks on the frame are very obvious. After more than a week of use, there have been relatively small wear marks.

Xperia Z2 eliminates the explosion-proof membrane that is easy to scratch, which not only improves the screen display effect, but also improves the texture of double-sided glass. After more than a week's use of streaking, there is no need to worry about scratches on the double-sided glass.

This may be due to the removal of the explosion-proof membrane. The height difference between the back of Xperia Z2 and the frame is obvious, and there may be an obvious scratch feeling when holding it. Of course, with this design, placing Xpeia Z2 on the desktop also avoids the direct friction of the glass panel and reduces the possibility of scratches.

Summary:

In terms of appearance design, Sony Xperia Z2 still continues the award-winning OmniBalance full balance design, provocative color matching and Japanese simple design. Xperia Z2 can be said to be quite popular with people who are pursuing design. Of course, several flagship models of the entire Xperia series have the same design, which really makes people tired of watching.

In terms of hardware configuration, Xperia Z2 is of course the standard flagship level, but both the theoretical score and the actual game test reflect that efforts still need to be made in optimization. Of course, as an international manufacturer, the system UI is also very careful about adding new functions, so the overall Xperia UI is becoming more and more perfect. Of course, it is not suitable for people who like the flat style.

Of course, I prefer to regard Xperia Z2 as the final embodiment of a design concept, such as IPS screen, larger screen, lighter body, stronger performance and endurance, integrated frame and the removal of explosion-proof membrane. With so many details, I prefer to call Xperia Z2 the complete final upgrade of Xperia Z. It can even be said that Xperia Z1 is actually Xperia Z Plus, while Xperia Z2 is actually Xperia Z Ultimate.

In fact, Xperia Z2 represents Sony's more ambitious and resource integration. For example, the 5pin interface enables the support of noise reduction headphones and stereo microphones, as well as the update of programs such as walkman, photo albums and movies, and more places where themes can be set. Xperia Z2 is more like a rally number, integrating the resources of many departments under Sony, which is also more desirable.
