In July 2016, Xiaomi released its first notebook, Xiaomi Air, and a few months later, it added 4G Internet access function and upgraded it to launch the Xiaomi Air 4G. As the second notebook product of Xiaomi, is it worth starting with this Xiaomi Air 4G 12.5 '' laptop launched in cooperation with mobile?

Appearance&Packaging

There is no change in the appearance design of the Xiaomi laptop Air 4G 12.5 ''. The only change is that the antenna part necessary for the 4G Internet access function has been added. The hardware has not been upgraded like the 13.3 '' version. It still uses the 6th generation Core M3. The A-side, AKG and Dolby sound effects that are very "distinctive" have also been completely preserved.

Screen quality

The Xiaomi laptop Air 4G 12.5 '' has no change on the screen. The 12.5 inch FHD (1920x1080) IPS screen, with the official parameters of 300 nits of brightness and 600:1 of contrast, is tested with software. The actual measured data shows that the maximum brightness is about 360 nits and the contrast is 1062:1, which can be said to exceed the official parameters; The color gamut is average, covering only 66.6% of sRGB.

The color temperature of the Xiaomi laptop screen is about 7000K, slightly cold. The average DeltaE in the color level test is 4.3, and the maximum DeltaE is 23.3. As a laptop screen, it is standard. The actual appearance is not satisfactory, and the experience is satisfactory.

Performance&System

As mentioned earlier in the article, the Xiaomi laptop Air 4G 12.5 '' does not have any hardware upgrades. It is also a combination of the 6th generation Core M3 6Y30+4GB LPDDR3, without the 13.3 '' version of Core i7-6500U and DDR4 memory. According to the official parameters, the CPU of this 6Y30 can reach 2.2GHz, but it is displayed as 0.9Ghz-1.5GHz in the system information; The GPU part is the integrated Intel HD Graphics 515, which is completely consistent with the previous non 4G version.

Using Cinebench R15 to test, OpenGL is 35.7fps, CPU score is 191cb, which is almost the same as the performance of Samsung TabPro S with the same processor. However, in practice, the Xiaomi laptop is not as smooth as the Samsung TabPro S. It always has a dull feeling and has a slightly slow response speed. It may be the reason that Xiaomi pre installed the system. 3D Mark and other test software could not run normally, so there was no relevant test results. As a reference, we can go to our love computer before Evaluation of Samsung TabPro S View the test data of 6Y30. The Xiaomi notebook Air 4G 12.5 '' has not been upgraded in terms of performance. Its positioning is still mobile office. In daily use, it focuses more on document editing and video entertainment, but not too much on games.

As an upgraded 4G function, the system is pre installed with an app for data free row, which can quickly check the relevant situation of mobile traffic, and also control whether the 4G Internet access function is enabled. At the same time, the network part of the system has also been integrated. It can be seen that compared with ordinary laptops, there is more "mobile network" part, and you can freely choose to use CMCC 4G Internet access and office or home Wi Fi.

What I have to say is that the function of this free data row is too weak. In addition to seeing how much traffic is left, there is only such an introduction to the public account. Traffic gas stations are useless because Xiaomi and Mobile are not open now. Only 4GB of traffic can be used every month, which is basically enough for pure web browsing. However, once you watch some videos or photo websites like Pinterest, it is very urgent and will automatically shut down 4G Internet access after running out of traffic, It will be awkward if you just run out of traffic when using it outside.

Endurance&Others

In our regular laptop endurance test, the Xiaomi laptop Air 4G 12.5 '' has a good endurance performance, ranking first in the comparison model, and also slightly better than the Samsung TabPro S with the same processor. The difference between the two is only 5% in online video, and the power consumption in games and web browsing is the same. Although the official website says that online video can be played for 9.5 hours is unrealistic, 5 hours is still no problem.

As an upgrade part of the 4G Internet access, the same 30 minute microblogging test was conducted. Without opening the video, it used about 80M of traffic and consumed 9% of power. Compared with Wi Fi, the power consumption is 2% more, which is acceptable. The measured speed is good. In addition to occasionally being affected by the unstable network speed, for people with mobile office needs, the direct built-in 4G Internet access is much more convenient than connecting to mobile phone hotspots. What Xiaomi needs to solve is that the currently bound package cannot meet the diverse needs of users.

tail

Unlike the 13.3 '' version, which provides more powerful processor options, the 12.5 '' version really only adds the 4G Internet access function, but the price of the non 4G version is 3499, while the 4G version is 4699. The difference of 1200 yuan for users is only the monthly 4GB traffic of a year. This alone makes users less persuasive. Admittedly, the built-in 4G Internet connection is attractive to users who need mobile office, but the flexibility and diversity of the Xiaomi and mobile packages are a little poor, which is a chicken bone at this stage. If you can add traffic gas stations and provide more Internet packages in the future, the 4G version of the Xiaomi laptop is worth considering.
