One screen is not enough to see ZTE Axon M/YOTA3/Meizu PRO7 satisfy you

As the saying goes, good things come in pairs. If you want to buy things in pairs, especially the second half price dessert at McDonald's, and the two package mail treasures on Tmall Then you may not miss two screens mobile phone 。 Although full screen is popular, the experience brought by two screens in one mobile phone is unique.

In this issue of Sharp Phone Duel, we chose three phones with two screens for comparison: ZTE Axon M, YOTA3 and Meizu PRO7 Plus 。

Sharp Phone Duel

In this issue of Sharp Phone Duel, I will compare these three dual screen phones horizontally from the aspects of appearance, system, performance, photography, and endurance. If you only see one of these functions, you can directly jump to the page you want to see. Next, let's start with the appearance of these three dual screen computers.

YOTA3、 ZTE Axon M Meizu PRO7  Plus

※ [Extraneous remarks: we hope to make some changes in the new year in the weekly change column of Sharp Phone Duel to make it more suitable for users, so readers, if you have any comments or suggestions on this column, please put forward in the comments, and we will seriously consider your suggestions]

Appearance: three types mobile phone Six screens

The second screen of these three mobile phones shows different forms. Let's first look at the materials of these three mobile phones.

Positive comparison of mobile phones

These three mobile phones all use metal+glass body, especially ZTE's Axon M, which has a very strong design, It can be said that it is "the folding heterogeneous in the era of full screen". and Meizu PRO7 Plus As for YOTA3 and YOTA3, they are generally round, and you can feel the perfect connection between metal and glass when you start.

Phone back contrast

The back of the phone here refers to the back of the ZTE Axon M without unfolded folding screen, which is still one piece 2.5D fifth generation Corning gorilla glass covered screen. and Meizu PRO7 Plus is a small picture screen and YOTA3 is an electronic ink screen.

Comparison of mobile phone details

After unfolding ZTE Axon M, you can see the back, The shaft of ZTE Axon M has just the right damping, which will not cause the shaft to wear easily due to excessive resistance, and will not cause looseness due to too small resistance. When it is opened or closed, the shaft will make a mechanical running sound of "click".

         Meizu PRO7 Plus's screen also has The 1.9 inch color AMOLED screen, with a resolution of 240 * 536 and a brightness of 350nits, has a good visual appearance. YOTA3 The electronic ink screen on the back has a resolution of 1280 * 720 and a pixel density of 282. Because it is a black and white screen, the display effect is completely beyond imagination. There is no jagged screen. It can even replace the Kindle to some extent after being used for a long time.

Comparison of mobile phone details

The chin comparison of the three mobile phones, because these three mobile phones all use the design of two screens, they also do not focus on the full screen. On the chin, ZTE Axon M uses the virtual key inside the screen, YOTA3 is a home key that cannot be pressed and navigation keys on both sides, Meizu PRO7 Plus is a classic mTouch design, and its home key can be pressed.

Comparison of mobile phone details

In the bottom comparison, the three mobile phones all use USB Type-C interface. YOTA3 gives up the 3.5mm headphone jack, while ZTE Axon M's headphone jack is located at the bottom of the body.

Comparison of mobile phone details

From the top, we can see that there is a noise reduction microphone opening on the top of the three mobile phones. From this perspective, we can clearly see the design of ZTE Axon M's rotating shaft.

Comparison of mobile phone details

At the back of the body, YOTA3 mobile phone and Meizu PRO7 Plus are volume keys and power keys, and ZTE Axon M is a semi cylindrical shaft design. From this perspective, we can also see that the overall design style of ZTE Axon M is more robust.

Comparison of mobile phone details

The forehead of the three mobile phones is also quite interesting. ZTE Axon M has a camera and a dual color temperature flash on the forehead of one of the screens. The other two mobile phones are earphones and front facing cameras. Since no full screen is added, the forehead of the three mobile phones is wide.

Comparison of mobile phone details

On the design of the left side of the phone, ZTE Axon M will The physical keys are concentrated on the side that can be opened and closed, including the volume key, the power key that can be pressed by integrated fingerprint identification, and the camera key. YOTA3 and Meizu PRO7 Plus are a dual card dual waiting slot, and there are no other modules.

These three dual screen mobile phones are different in design, especially ZTE's Axon M, but with these three phones in hand, the turnaround rate should not be low on the road.

System: private customization for dual screen

In terms of systems, these three companies are equipped with their own deeply customized systems based on Android, and all have good adaptation to dual screens. ZTE Axon M is equipped with the Axon M CN 1.1 system, which is deeply optimized based on Android 7.1.2. It performs well in terms of smoothness and basic functions, but there are some bugs in the interaction of photography. I believe that later updates will solve this problem.

ZTE system interface

Axon M CN 1.1 can be said to be a relatively pure soul. The overall style of the internal interface settings is close to the native Android system. Icon drawing creates a three-dimensional card like effect through shadows. Single screen mode and common mode mobile phone The difference is not big. It should be noted that the camera is on the main screen and there is only one camera. The default photographing mode when the camera is turned on is self portrait. For regular photographing, the picture needs to be moved to the secondary screen. In other words, ordinary mobile phone self taking and regular taking are camera switching, while ZTE Axon M is screen switching.

In addition, ZTE Axon M also provides options such as image mode and expansion mode. stay Software In terms of common software, ZTE's dual screen system has been well adapted.

YOTA3 system interface

YOTA3 is equipped with a system based on Android 7.1.1. The whole system looks relatively simple. Many of the functions in the system are customized exclusively for the back ink screen. For example, one click at the bottom right corner of the home page can switch between the front and rear screens. Long press the power key to select the single ink screen, etc.

In general, the YOTA3 system is relatively easy to use. The overall style is also flat, and small functions such as time lock screen and call reading can be set. In a small system like dual screen system, it is difficult to achieve strong functionality and smooth use.

Meizu PRO7 Plus System interface

         Meizu PRO 7 Plus It is equipped with Flyme 6 system based on Android 7.0, and the default theme of boot is Dream Edition. From the perspective of system functionality, Flyme has always been a representative of complete functions. Flyme has everything from control of system applications to cloud services and local backup. Meizu has established a more comprehensive ecosystem service, with music, video, news information, life services, application center and other resources.

The three mobile phone systems have also done a good job in the dual screen adaptation of their own, but there are some bugs. After all, it will take some time for the niche mobile phones equipped with dual screens to become more mature.

Shed shooting: three types mobile phone Excellent test data

Shed photography is a standard for us to judge mobile phone photography, and it is also a link for us to evaluate mobile phones. The essence of photos can not be separated from several dimensions, such as resolution, color orientation, white balance, tolerance, etc., so our evaluation standard starts the standard photography environment, builds a datable photography template, and uses Imatest Software Quantify the test data, and finally obtain authentic and reliable evaluation results.

Analytic power refers to the ability to distinguish the details of the original object. The better the analytical power is, the better the control over the details will be, and the transition of the details of the picture will be more natural. There are many ways to test the analytical power. Here we choose the linear test method. Its advantage is that it is very intuitive and can be observed with the naked eye. We cut some positions of the test samples as the test area to test the analytical power of three mobile phones.

Analytical force comparison

It can be seen that ZTE Axon M, equipped with 20 million pixels, has excellent performance and higher image sharpness in terms of resolution. YOTA3 and Meizu PRO7 Plus Similar performance.

Shoot the 24 Color Check test card in the studio environment, and obtain the color deviation value Δ E and white HSV saturation through Imatest analysis. The color difference Δ E is actually the difference between the measured color and the real color. The greater the difference, the more serious the color deviation.

Color restoration contrast

In terms of color restoration, YOTA3 and Meizu PRO7 Plus has reached the full score level of Zhongguancun online mobile phone evaluation standard. ZTE Axon M is also close to full score. The performance of the three mobile phones in color is close to reality, and the color is not too bright.

White balance is an indicator to describe the accuracy of white produced by mixing red, green and blue primary colors. Many people will encounter such problems when they use digital cameras to shoot: the images taken in the fluorescent room will appear green, the scenes taken under the indoor tungsten light will turn yellow, and the photos taken in the sunlight shadow will somehow turn blue, because of the "white balance".

White balance contrast

In terms of the performance of white balance, YOTA3 performs best, and the white balance is restored accurately. ZTE Axon M and Meizu PRO7 Plus's performance is similar.

Dynamic range refers to the brightness range of the subject - the brightness span from the darkest point to the brightest point in the subject. Take the gray scale color card in the studio shooting environment, and calculate and analyze the dynamic range level of the camera through Imatest. The larger the value, the better. If the total value exceeds 6, the full score will be given.

Dynamic range performance

It can be seen that both ZTE Axon M and YOTA3 are at the full score level, and Meizu PRO7 Plus is also close to the full score.

In general, these three mobile phones performed very well in the laboratory studio shooting. Let's take a look at the actual sample performance.

Real shot: single and double shot mixed fight with various playing methods

After watching the data comparison of the studio shooting, let's take a look at these three models mobile phone How about the performance of the live shot samples of.

Judging from the live photos, YOTA3 and Meizu PRO7 Plus The overall tone is similar. ZTE Axon M selects low noise points in terms of exposure and noise, which also causes some pictures to be dark. But in terms of analytical power, as in the studio shooting test, it is very sharp. However, these three dual screen phones that do not focus on photography all perform well in terms of photography, which is sufficient for daily use.

Performance: leading performance of the flagship of the previous generation Snapdragon

ZTE Axon M does not use the current normalized Qualcomm flagship processing platform Snapdragon 835, but the previous generation flagship Snapdragon 821 mobile platform. It is said that because the product project was established earlier, it is natural that the new product design requires longer R&D time.

The Snapdragon 821 adopts the 14nm FiFET Samsung second generation LPP process technology, four core 64 bit Kryo CPU and Adreno 530 GPU. The main frequency of the two large cores is increased from 2.2GHz of the previous Snapdragon 820 processor to 2.4GHz, the main frequency of the two small cores is increased from 1.6GHz to 2.0GHz, and the main frequency of the GPU is increased to 650MHz.

        YOTA3 mobile phone It is equipped with Qualcomm Snapdragon 625 mobile platform. Snapdragon 625 is Qualcomm's first eight core processor built with a 14nm process, which is in the same process node as Snapdragon 820 and also supports Quick Charge 3.0 fast charging technology.

         Meizu PRO7 Plus It is equipped with the flagship processor Helio X30 of MediaTek. Helio X30 uses two 2.6GHz A73, four 2.2GHz A53 and four 1.9GHz A35 Compared with Helio X20, the computing performance is improved by 35% and the power consumption is reduced by 50%. MediaTek boldly adopts the most advanced 10 nm process of TSMC, which improves the performance by 22% compared with the 16 nm process and saves 40% of electricity. With PowerVR Series7XTPlus GPU, the main frequency reaches 800MHz. Compared with Helio X20, the graphics performance is improved by 2.4 times and the power consumption is reduced by 60%.

Angora rabbit 6.3.3 Running score test

3D Mark run test

We uniformly used version 6.3.3 of Anthare to test the running points of these three mobile phones. It can be seen that ZTE Axon M equipped with Snapdragon 821 and China MediaTek Helio X30 Meizu PRO7 The run points of Plus are similar, which is also confirmed by the run points of 3D Mark. The YOTA3 equipped with Snapdragon 625 is weaker.

However, based on the respective positioning of these three mobile phones, it is not a problem for such performance to meet daily use. Especially for users who like to use their mobile phones to read e-books, the importance of battery life must be greater than that of game performance.

Charging and summary: how to play with two screens

We are interested in these three mobile phone Carry out charging test for 30 minutes respectively. First, consume the power of these three mobile phones to 0%, and then charge the mobile phones with the original charging head to get the charging curve within 30 minutes.

30 minute charging curve

It can be seen that after 30 minutes of charging test, Meizu PRO7 Plus The Super mCharge used performs well, charging 70% of the power in 30 minutes; The Qualcomm fast charging technology adopted by ZTE Axon M and YOTA3 also charged nearly 50% of the electricity in 30 minutes, both of which performed well.

In terms of battery life, because the three mobile phones are used in different ways, it is impossible to unify a battery life test model. According to the use of the author in recent days, ZTE's Axon M has a good endurance in the use of a single screen, but when the two screens are fully open, the power consumption of two 1080P full HD screens will be amazing, and the endurance will be affected.

When YOTA3 uses the ink screen alone, the electrode consumption is low. When the color screen is turned off, it only operates the e-book, and only consumes 3% of the power in two hours. This is very difficult for users who like to read e-books. Meizu PRO7 The front of the Plus is equipped with a 2K screen, and the 3500mAh battery still has 27% power left after a 5-hour heavy endurance test. The performance is satisfactory.
