I vaguely remember that last August, ZUK released a new mobile phone, ZUK Z1, which gave us the definition of ZUK, and also let us know what a free guest is. ZUK Z1 is simple, honest and plain. The hardware configuration is very mainstream, and the system UI is also very clean. ZUK Z1 is also complex. All details are carefully crafted. Even a small icon gives it strong vitality. In this way, simple and complex are combined to form a unique ZUK Z1. Most of the friends who have experienced Z1 will be impressed by its U-Touch fingerprint recognition. Returning, switching tasks, returning to the home page, and multi task viewing are not easy. What's more, the speed and recognition rate of U-Touch integrated press fingerprint recognition are good.

Less than a year later, following the high-profile release of the ZUK Z2 Pro in April, a small screen product, the ZUK Z2, was released again at the end of May. In this age of big screens, iPhone The release of SE has set off a "small era", which is more suitable for single handed mobile phones. Can you catch up with the small screen super flagship Z2 of iPhone SE and gain your heart? Today, let's walk into ZUK Z2， What are the new highlights?

Without too much decoration, the packaging of Z2 is simple and clear. The top of the box is the front of Z2, and the bottom is the parameter information. Z2 is also a great work of ZUK after its return to Lenovo family. Lenovo and ZUK are marked on the side of the package Identification of Z2. The whole package is in the form of a heaven and earth box, and the outside is wrapped with film.

In the packaging box, below the Z2 are accessories: power adapter and data cable, 5.3V/2.5mAh power adapter, round and flat, small, white paint is more beautiful and refreshing. The data cable is thicker than ordinary wires. It still uses Type-C interface, and it is convenient to plug the front and back casually. The standard configuration of Z2 does not include earphones. Hi Fi earphones can be purchased separately. After all, at the price of 1799, you can use Snapdragon 820. What else do you want?

ZUK Z2 adopts double-sided 2.5D suspension glass, which is transparent and bright. No matter at which angle, you can see the light and shadow left by the reflection of light. The front of Z2 is very simple, and there is no excessive opening on the top. The general position of the top speaker is given to the light sensor, and it is slightly concave. The front camera is located on the left. There is only one entity HOME key at the bottom, which has fingerprint identification function.

Tired of the three-stage design of the back of the phone, the integrated design of the back of the Z2 is more complete and beautiful. It looks like a mirror, smooth and flat, and can slide gently even on a book with a small angle bevel. The rear camera is located in the upper left corner, slightly concave, with the flash on its right side, and the middle position below the back is marked with ZUK logo。 If you don't look at the logo and only look at the parts, you may think it is a new product of Smartisan series.

ZUK Z2: 141.65mm x 68.88mm x The 8.45mm fuselage is slightly smaller. Unlike other mobile phones, the Z2 does not use a composite metal middle frame. Instead, it uses high-strength glass fiber material, with a layer of metal particle coating on the surface, which gives it a slightly frosty feel.

It keeps the left side flat and smooth. The volume key, power key and SIM card slot are placed on the right side. The headphone connector, MIC, Type-c connector and speakers are arranged in order at the bottom, compact and practical.

ZUK Holding Z2 in hand, it looks like the resin frame put on the iPhone 5S anodized aluminum frame a few years ago to stop cutting hands. In addition, the small angle chamfer of the fiberglass middle frame gives me back the original 5S like feel. The body weight is 149g, and it will not be burdensome to hold in the hand. It is suitable for single hand operation, that is, single hand operation by girls, and it will not be too difficult.

Speaking of ZUK Z2， The first reaction of many friends was the cost-effective Qualcomm Snapdragon 820 configuration, the top high-end Snapdragon 820 processor, which ensured the hardware level of the Z2 machine and strengthened the position of the Z2 in the flagship Android machine.

Hardware alone is no good. ZUI can be said to be the software strength of ZUK Z2. ZUI is based on Android 6.0.1 Deeply optimized system, flat icon design, simple and fresh, natural, clean and refreshing. In details, the weather, time and calendar will change with the parameters. The small moving eyes of information icons make the whole interface more lively.

U Health is ZUK The built-in functions of Z2 are also the pioneers of the ZUI system. After entering the system, the first thing to enter is the U health interface, which can automatically identify the movement mode according to your personal information, and record the time, steps and distance in real time, thanks to the six sensors on the Z2 body: 3-axis acceleration, 3-axis gyroscope, 3-axis electronic compass, distance sensor, light sensor and Hall sensor, It can accurately calculate the user's motion track. U health is not only displayed as an application icon, but also as an interface in the ZUI system. You can see it on the left page of the home page by sliding it to the right. Zuk began to focus on user health, which is also a reminder that we should not forget to exercise more when building computers.

▲ U-Touch settings

Used ZUK Z1 users all know that U-Touch is a highlight of Zuk. It is the most powerful button in the smart phones I have used. This HOME key can realize seven operation functions: press it to return to the main page; Double click for task management; Tap to return; Slide left and right to switch applications; There are also two customized function keys, long touch and long press, which can define other functions or directly open an APP. I define long touch to turn off the screen. Long press to turn on the camera is also very convenient for capturing. Of course, the fingerprint recognition function is indispensable. The unlocking is basically completed in 1 second, and the success rate is quite high. It can skillfully superimpose several common user operating habits on the HOME key and count them. Only Zuk can do the best and completely squeeze HOME's mobile phone operations.

Of course, if the fingerprint identification function is only used as the unlocking function, it would also be a waste of the Sense of Snapdragon 820 ID ultrasonic identification technology, WeChat payment and Alipay payment are all swiped. As long as you click fingerprint payment and set association, you can use the fingerprint payment function immediately, and you are no longer afraid of password disclosure.

▲ Synchronize iClound on ZUK Z2

For the first time, I found the function that can synchronize iCloud on Android smart phones, which is very convenient for Android and iPhone to change phones. With this function, I can also retrieve the 5S data I lost before, and it feels like I can use the original 5S again. Currently, only calendar and address book data can be synchronized, and more data should be released later. If you have a lot of anniversaries or a large number of address book data, this function is convenient for users to change phones. Many Android smartphones I have played do not have this function. My first contact will give me a feeling of being tall.

▲ ZUK Z2 charging test (it takes about 2 hours to fully charge)

ZUK The battery capacity of the Z2 body is up to 3500mAh, which is really large, more than double that of the iPhone 5S. Z2 supports dual core parallel fast charging, OTG reverse charging, and 5.3V/2.5A charging head. However, after a few days of trial use, I feel that the charging is still a little slow. Compare the OPPO of charging for five minutes and talking for two hours For R9, it takes a few minutes more than an hour to fully fill, while for Z2, it takes about two hours to fully fill. The clue is that R9 uses Helio of MediaTek The P10 eight core processor focuses on low power consumption. The Z2 uses the Snapdragon 820 processor that has never been castrated, and the power of the Z2 is a quarter more than that of the R9. Maybe this is the price of using the flagship processor. If you have a high demand for charging time, you still need to weigh again and again.

Overfrequency is originally exclusive to the PC platform, which increases the working frequency of hardware such as CPU, so that the machine can work efficiently and stably at a fixed frequency, thus improving the working speed of the computer. Later, in order to pursue higher performance of mobile phones, it was also derived into the mobile phone industry. ZUK The Z2 is equipped with the standard version of Qualcomm Snapdragon 820, that is, the main frequency is 2.15GHz, which is different from other castrated 820s that have undergone frequency reduction processing. After updating to the ZUI2.0 version, the one button overclocking function can be realized, which can reach 2.3GHz. The 2.15GHz standard version of Qualcomm Snapdragon 820 is enough to run most mobile applications smoothly. Although the overall performance improvement is not obvious after the one click overclocking is mentioned to 2.3GHz, it is also a highlight to attract many mobile phone enthusiasts to take precautions for applications with higher demand in the future.

In addition to the Bloody Snapdragon 820, Zuk has also made great efforts in GPU. It is equipped with the current powerful Adreno series graphics chip Adreno 530 and Adreno Compared with 430, the graphics computing performance of Adreno 530 is improved by 40%, while the power consumption is reduced by 40%. Plus 4GB LPDDR4 RAM and 64GB storage (eMMC 5.1) Combination is absolutely the hardware configuration standard of the flagship machine.

The 7-mode 22 frequency has truly realized global roaming, fully covering the 4G, 3G and 2G network systems of the three major operators, and supporting the 4G+network services of China Telecom, China Unicom and China Mobile. At the same time, it supports the latest 4G voice technology VoLTE. Voice calls do not need to fall back to the 2G/3G network. All services are carried on the 4G network, which can realize the unification of data and voice services under the same network, and also provide high-quality audio and video calls. In addition, ZUI has also improved a lot in functions, including support for chip level identification and anti-counterfeiting base station SMS algorithm, support for SMS harassment interception and anti fraud prompt, etc. Mom no longer has to worry that I will be cheated.

Taking photos is also an important indicator for our users to purchase mobile phones, Lenovo ZUK Z2 is equipped with 8 million pixel front camera, 13 million pixel main camera, 5P mirror set, aperture of F2.2, Samsung new generation sensor, and 1.34 μ m large pixel customized CMOS design, true restoration of image color. In addition, ZUK Z2 also supports the PDAF+CAF dual focusing mode, which can achieve 0.1 second extreme focusing. In terms of actual photographing experience, the mobile phone has fast focusing and imaging speed, which can reflect the advantages of dual focusing mode. The white balance performance of most scenes is relatively accurate, but there are still some deficiencies in image details. In a weak light environment, there will be obvious out of focus and slow response. Small screen super flagship ZUK The Z2 failed to use the optical anti shake component, which is a little pity for users who often shoot on their mobile phones. The actual shooting ability of Z2 is shown in the picture.

The camera software is simple and convenient. There are not too many parameters in professional terms. The overall operation is simpler. Slide the camera frame from right to left to call out bright, delicious LOMO、 Evening, soft, black and white and other rich filters. Only scale HDR、 Fast action, slow action, panorama, flash selection. Other settings need to be modified in the camera settings. It is worth mentioning that the Z2 rear camera provides slow motion video up to 960fps, which is also one of the best in the mobile phone industry, basically catching up with the Sony RX100 MK4's professional level.

As a small screen super flagship phone priced at 1799 yuan, Lenovo's ZUK Z2 has a strong hardware configuration and ZUI Supported by the 2.0 system, it has a smooth performance like flying. The simple, clean and self-contained appearance style, powerful functions and various operation patterns of U-Touch make the experience of the ZUK Z2 much better. of course, ZUK There is still room for improvement in some details of Z2, but considering the current competition and cost in the domestic mobile phone market, the price of 1799 yuan is already very cabbage. In other words, Lenovo ZUK The Z2 is not necessarily the best choice for the flagship, but its configuration is very attractive relative to its price. It is well deserved that Lenovo's ZUK Z2 will definitely be a dark horse for this year's small flagship aircraft.
