Once upon a time, China Cool Union dominated the whole domestic mobile phone market. However, with the substantial reduction of operator subsidies and the rise of Xiaomi, Meizu, 360 and other Internet mobile phones, China Cool Union has been disintegrated. Huawei, relying on its strong R&D capabilities, worked together online and offline to maintain its first position, while ZTE Coolpad is gradually out of our sight, but actually they are not far away, just consumers are unwilling to pay for it. ZTE also launched its flagship model ZTE Tianji 7 with Qualcomm 820 this year, with a price of 3099, and the top version is up to 4099. Although Coolpad has not yet launched the flagship mobile phone of Qualcomm 820, its Coolpad Platon with Qualcomm 800 is priced at 3699. Lenovo, however, has felt that the times are different. In the domestic market, where price performance is paramount, if it still makes its mobile phone price firm, it is doomed to fail to retain users.

So last year, Lenovo's Miracle Factory launched a new mobile phone brand zuk, and released the Zuk Z1. This beautiful, high-end configuration, but affordable mobile phone instantly dazzled many people. This year, the Zuk brand, once independent, officially returned to Lenovo, and this year released the second generation product of the Zuk brand, the Zuk Z2, It not only has a powerful hardware configuration of Qualcomm 820+4G+64G, but also has a 1080P full HD LTPS screen, fast charging and better use U-Touch 2.0, and has also lowered the price to 1799 yuan, which undoubtedly makes it the lowest price Qualcomm 820 mobile phone on the market at present. Lenovo's move is just hoping to return to people's attention with its cost-effective ZUK, As the Qualcomm 820 mobile phone with the highest cost performance ratio at present, how about its actual experience.

Packaging: simple design, less accessories.

ZUK Z2 is packed in white cardboard box, with the product picture printed on the front. At present, ZUK Z2 has two kinds of color matching: white version and black version. The one I experienced is white version. The ZUK Z2 has the mainstream flagship configuration of the current Android machine, but the price has been cut to 1799 yuan, so there is no need to require more parts for the ZUK Z2.

Appearance: Minimal design, smooth feel

The front of the ZUK Z2 uses a 5-inch 1080P screen. The overall size is 141.65 * 68.88 * 8.45mm, and the weight is 149g. As a 5-inch model, I feel that the size can be smaller and the weight can be lighter. In terms of appearance, ZUK Z2 achieves the most concise mobile phone design at present. There is no distance sensor, light sensor, left and right virtual touch keys at the bottom, or even the product logo. In fact, as an Android machine, the ZUK Z2 really eliminates the left and right virtual keys, and can complete all the functions of the three virtual keys of an ordinary Android machine only by relying on one fingerprint identification key. It is believed that in the new machines launched in the second half of the year, there will be more handsets imitating the fingerprint function key of ZUK.

Careful people will find that the original distance sensor and light sensor are hidden in the receiver. In fact, this design was first done by the hammer in order to get a more concise front face. The front camera adopts an 800w pixel camera with f/2.0 aperture, which supports the current mainstream intelligent beauty function.

The back of the fuselage is still simple. The front and back of the ZUK Z2 are designed with 2.5D glass. For a year when the all metal fuselage flies everywhere, a mobile phone with double glass will look particularly fresh. In addition, because of the glass material, it is finally unnecessary to tolerate the uneven three-stage back design. This not only looks more beautiful, but also feels smoother.

The rear camera adopts Samsung's new generation 1300W pixel camera with f/2.2 aperture. It supports the dual mode focusing of PDAF+CAF. The EIS cooperates with the sensor to assist anti shake. The focusing process can be completed as soon as 0.1 seconds. It also supports the recording of 4K video. From the camera's parameters, it is still the main stream. The actual use effect will be tested in detail later.

The middle frame of the mobile phone is made of high-strength glass fiber. The advantage of using this material is that it can not only be integrated with the upper and lower glass, but also not need to design the upper and lower white belt breakpoints like the metal body. The overall design is more unified and complete. The whole fiberglass middle frame has been sanded to prevent slipping. In order to keep the simplicity of the phone, there is no keyhole on the top and left of the ZUK Z2.

All the holes and slots are designed at the bottom of the phone. From left to right, there are 3.5mm headphone holes, noise reduction microphone, Type-C interface and loudspeaker holes. The Type-C interface that can be inserted in the front and back has always been the standard configuration of high-end mobile phones. Although the price of the ZUK Z2 with Qualcomm 820 is only 1799 yuan, it has not been castrated, which is commendable. In addition, the author has always believed that the design of the earphone hole at the bottom of the mobile phone is more suitable for our usual use habits.

On the left side of the ZUK Z2, from top to bottom, there are volume up, volume down, power key, and SIM card slot.

The current mainstream dual card dual standby All Netcom 3.0, dual Naon SIM card slot design, does not need to distinguish between the primary and secondary cards. Some mobile phones will support memory card expansion in the card slot, while the ZUK Z2 has 64GB built-in storage, so there is no need for expansion.

The combination of the front and rear glass of the ZUK Z2 and the fiberglass middle frame makes it look more simple and beautiful. However, it may be because of the white version, which makes it slightly more plastic. If it is a black version, I believe it will have a better visual effect.

Screen: delicate display, not colorful

The ZUK Z2 is equipped with a 5.0 inch 1080P LTPS screen. The PPI reaches 441, and the maximum brightness of the screen is 400nit. In terms of parameters, this ZUK Z2 screen is fairly standard. After all, from the naked eye, there is no difference between the 1080P screen and the 2K screen. The real meaning of the 2K screen is that VR may be more practical. In addition, the 2K screen will only bring more power consumption, but also reduce the performance of the phone. What's more, the ZUK Z2 is only a small screen phone with a screen of 5.0, and the 2K screen is meaningless. In order to restore the display effect of ZUK Z2 to the greatest extent, the camera mode of the following photos is manual: white balance 5500k, aperture f/9, shutter time 1/4s, ISO100， All photos are processed in size. From the actual display effect, the color restoration is also more accurate. In addition, the ZUK Z2 does not make the color more bright because it wants to please the eye. Its not bright color display can also make you feel less tired after watching for a long time. Moreover, the 1080P display effect is relatively delicate.

Photo: The function is still lacking, and the quality needs to be improved.

ZUK Z2 is relatively simple in terms of camera functions. At present, the camera app only supports flash, panorama, fast action, slow action In addition to HDR and 4:3 or 1:1 ratio adjustment, as well as several filters and other functions, many domestic mobile phones have no camera functions, such as professional night view mode, watermark mode, taking pictures before focusing, countdown shutter, voice controlled shutter, etc., especially the most basic manual mode. Therefore, This camera of ZUK Z2 is not very playable. It is only suitable for girls who take photos in automatic mode.

The ZUK Z2 is equipped with a 1300w pixel rear camera with f/2.2 aperture. Because it uses the dual mode focusing of PDAF+CAF, it is very fast in focusing speed. Then it uses EIS with sensor assisted anti shake technology, which will make it easier to take higher quality photos in capturing use. What is the actual photo taking effect? Now let's take a look at the photo samples of ZUK Z2. All samples are only processed in size.

From the actual photo samples, In the case of sufficient light, the picture taking effect and color restoration of the ZUK Z2 are good. However, if the light is not good, the analytical power will be lacking, and there will be a bit more noise. This kind of picture taking quality is still slightly inadequate in the price of the ZUK Z2. However, considering that this is a Qualcomm 820+4G All Netcom mobile phone, this kind of photo taking ability is reasonable.

System: based on Android 6.0, simple and smooth.

In terms of system, ZUK Z2 It is equipped with the ZUI 2.0 system based on Android 6.0.1. The system still adopts a flat and fresh style, and there are not too many services implanted in the system like other domestic manufacturers. There are still not too many miscellaneous settings in the system settings. The whole system looks very simple, and all applications in the system can be deleted according to user needs, And the system's last rabbit and thumb play is the author's own installation.

Pull down anywhere on the screen to open the notice bar of ZUK Z2. This notice bar is not embedded with a shortcut switch like other domestic systems, but must be pulled up at the bottom of the screen to open the shortcut switch. If pulled up elsewhere on the screen, a search bar will pop up. In addition, the background of the system of ZUK Z2 still uses the popular card design today. After experiencing too many domestic system UIs with basically the same interaction, this interaction mode brings people a new system experience and is still easy to use.

Although the system is relatively simple, it has basically all the functions that should be used, and it also adds a health management platform, which can not only record the steps, active duration, activity consumption and other data in real time, but also support the binding of health devices such as the ZUK physique analyzer and Jabra PULSE sports earphones to make sports more data oriented.

In addition, ZUK Z2 does not add an application theme, but you can have different theme styles according to the way you modify the wallpaper. When you select a wallpaper as your lock screen, the system will automatically process the wallpaper with ground glass, and then apply the processed wallpaper to the system. Of course, you can also set it as a clear desktop wallpaper, This also allows you to have your own personalized theme effect.

Fingerprint: U-Touch 2.0 integrates multiple functions to bring the ultimate experience.

ZUK Z2 has designed a fingerprint key on the front, which is defined by ZUK as: U-Touch 2.0， The new interactive mode directly integrates all the functions of the three virtual keys of an ordinary Android machine, and allows you to customize other shortcut functions. This innovative design has led to the most user-friendly fingerprint HOME key at present. When you become familiar with the U-Touch 2.0 interaction mode, you will find that the operation of the ZUK Z2 is very easy. Once you get used to it, you will never go back. In addition, because the left and right virtual keys are removed from the front of the screen, the overall appearance of the ZUK Z2 is more beautiful.

In terms of fingerprint identification entry, after several tests, each fingerprint entry requires 7+12 fingerprint entries to complete, which is slow. But once entered, this HOME key with multiple functions will bring you all kinds of happiness.

In terms of fingerprint function, it not only supports mobile phone unlocking and application unlocking, but also supports WeChat payment and Alipay payment functions. The only thing worth mentioning is that the current fingerprint payment design is not perfect. Because Taobao, JD, Didi, etc. basically support WeChat or Alipay payment, but when you make mobile payment in these third-party applications, you will find that these third-party applications still prompt you to enter a password. Only when you directly enter WeChat or Alipay will fingerprint recognition payment pop up. Now it is only expected that these third-party applications can also support fingerprint payment after the system upgrade.

Performance: performance monster, and support overclocking

In terms of hardware, ZUK Z2 adopts the current flagship configuration of Android, Qualcomm 820, Adreno 530 GPU, 4G storage, and 64GB emmc 5.1 memory chip. Just looking at this hardware configuration, there is no need to worry about its hardware performance. It can be said that both software and games can run smoothly as long as there is no software compatibility problem. Before the game, I'd better run one randomly. Maybe it's because many apps have been installed on the mobile phone, or maybe it's because the author has upgraded the ZUI 2.0. The score of my ZUK Z2 does not meet the expectations, but the performance score of more than 12w is fully qualified for all Android software and games. The score of 120042 divided into the score of ZUK Z2 for direct test, and the score of 125801 divided into the score of ZUK Z2 after overclocking to 2.3 of the main frequency. After overclocking, the score increased by more than 5000 points. In fact, all large games can still be played without overclocking. Therefore, the author believes that the overclocking function is more gimmicky than the actual application.

In order to test the real strength of ZUK Z2, the author tried to download several games. However, due to the compatibility problem of Android 6.0, many games were not installed successfully, including Speed Racing 8. After downloading Speed Racing 8 for many times, the author finally achieved his wish. After all, if you do not install large games, you will not be able to test their hardware capabilities. In addition, the author also downloaded a fearless Cheshen: Las Vegas, and finally found that the two games ran very smoothly, and there was no jam in the game, which shows that the performance of the ZUK Z2 is very powerful.

As for the game, if you can't install it, you are also welcome to leave a message to ask and answer one by one.

Fever:

The author played the game of Lonely Cheshen: Las Vegas for half an hour, and then conducted a temperature test on the ZUK Z2. The test found that the highest temperature of the ZUK Z2 came from the front camera part, the highest temperature was 38.2 degrees, while the highest temperature in other locations exceeded this value. From the test results, the heating problem of the Qualcomm 810 did not appear in the Qualcomm 820, Maybe it's because the 3D game doesn't take configuration. No matter how and how long the author plays, even if he finally turns on Speed Racing 8 and plays it for several times, the temperature of the ZUK Z2 still can't exceed 40 degrees. The author is very satisfied with such a fever.

Endurance charge:

A 3500mAh super capacity battery is built into the ZUK Z2, which makes the ZUK Z2 have good endurance. The author fully charged the ZUK Z2, and then adjusted the brightness and sound of the phone to 50%. After 2 hours of QQ and microblogging, the actual power consumption is 15%. Then I played the 3D online game Kung Fu Panda for an hour, and the actual power consumption was 22%. Then I used iQIYI to watch two hours of online video, and the actual power consumption was 21%. That is to say, after the author played the mobile phone for 5 hours continuously and intensively, There is still 42% power left in the ZUK Z2. From the perspective of the battery life, if the ZUK Z2 is used heavily, it will not have any problems during the whole day. It can be said that the battery life of the ZUK Z2 is very good. In addition, the author also tried the standby capacity of the ZUK Z2. After a night of standby, about 9 hours, the ZUK Z2 only consumes 2% of power.
As for charging, the power of the charger of the ZUK Z2 is 5.3V 2.5A, which is larger than the ordinary charging power. However, there is still a certain gap between the charger and the 9V Qualcomm Fast Charge. According to the actual test, the mobile phone can charge from 1% of the power for 10 minutes, and the power can reach 12%. After the charging time reaches 30 minutes, the power can reach 30%, and the ZUK Z2 can be fully charged. The author uses it for 2 hours and 3 minutes. For a mobile phone with 3500mAh large capacity battery, this kind of charging capacity is good.

Who is suitable for ZUK Z2:

1. Users who want to have the ultimate performance and price performance
2. Users who are tired of metal and plastic mobile phones should try the full glass ZUK Z2, which will have a more refreshing feeling.
3. Users who like a HOME key and can have all Android virtual key functions may not quit after using it.
4. Users who like small screen phones.

Who is not suitable for:
1. Users who like taking photos and have higher requirements for mobile cameras.
2. Users who like large screen phones.
3. Users who want their mobile phones to be recognizable, please go out and turn right to choose Apple and Samsung.

Summary:

As the most cost-effective Qualcomm 820 mobile phone at present, the ZUK Z2 is bound to attract many users just because of its high configuration and low price. In addition to its super performance, it also has an exquisite appearance, stable system, and U-Touch 2.0 that can not be returned. If you want to have a high cost performance mobile phone with extreme performance, the ZUK Z2 will be the best choice.
