On December 23, Xiaomi, together with China Mobile, released a new series of products of Xiaomi notebooks, which have their own 4G network, of which the 13.3-inch version has also been upgraded to the i7 processor.

This press conference brought two products, one is the Xiaomi laptop Air 4G 12.5, and the other is the Xiaomi laptop Air 4G 13.3. In terms of product appearance and size, it is consistent with the previous WiFi version of the Xiaomi laptop Air. As the name implies, this new series of products has added support for the built-in 4G network. How does it work?  

First, let's take a look Xiaomi Notebook Air 4G 13.3 It corresponds to the previous Xiaomi laptop Air 13.3. Although it looks no different, it has a relatively large upgrade range, which can be seen from the WiFi version of Intel Core i5-6200U (2.3GHz main frequency, Remax 2.7GHz ）Upgrade to Intel Core i7-6500U (2.5GHz main frequency, accessible by Remax 3.0GHz ）Although it is still a dual core four thread processor, the performance will be significantly improved when the maximum frequency is upgraded to 3.0GHz.

In addition to the CPU upgrade, other aspects are the same as the WiFi version, with GeForce 940MX Independent graphics card, 8G DDR4 Memory and 256G NVMe hard disk . Windows 10 Home Edition is preinstalled.

In some running states of the system, the i7-6500U is a dual core four thread processor with 512KB L2 cache and 4MB L3 cache.

The C-side keyboard, like the body shell, adopts a silver design, which is more uniform in style.

The thickness and weight of the Xiaomi notebook Air 4G are well controlled, and the 13.3-inch version only 1.37kg (WiFi version is 1.28kg), thickness is 14.8mm 。

The D side is also a metal body. Because of the unique display and fan, there are multiple heat dissipation openings at the bottom.

The biggest difference from the WiFi version is that there is a China Mobile 4G module on the side of the notebook, which uses e-SIM to connect to the private network. The 4G module itself cannot be disassembled, nor can it use its own SIM card.

At the place where the system is connected to the network, we can see that we have connected to the CMCC (China Mobile) network. The signal bar is consistent with the mobile phone, and is obviously different from the WiFi signal icon.

In the network connection properties, you can see the information of the 4G network adapter we are connected to.

Field speed measurement: due to poor indoor signal, the downlink is only 33.49Mbps.

The Xiaomi notebook Air 4G will have 4G free traffic every month, that is, 48G a year. If the traffic exceeds the limit, the network will stop. China Mobile has not yet provided a corresponding solution for the future billing of the excess. The system itself will also have traffic reminder software.

Obviously one size smaller Xiaomi Notebook Air 4G 12.5 , relatively speaking, the configuration will be lower, and of course its price is more affordable. It is still used Intel Core m3-6Y30 Processor, highest Rui frequency 2.2.GHz , is a Dual core four thread The processor for. In addition 4G memory and 128G SSD hard disk Configuration of. Xiaomi laptop Air 4G 12.5 weight is 1.08kg ， The weight of WiFi version is 1.07kg, which is close to each other, and the thickness is only 12.9mm 。

The Xiaomi notebook Air 4G 12.5 also has the 4G module of China Mobile, but it is located slightly close to the center of the fuselage.

Compared with the A-side of the two sizes of the Xiaomi notebook Air 4G, Xiaomi uses a logo free design, and provides a variety of official stickers for users to choose from.

Both notebooks adopt a narrow border design, and the B side uses a full glass panel, which is more visual impact than ordinary notebooks.

By comparing the two sizes, it can be seen that 13.3 inches is a circle larger.

The side comparison of the two sizes shows that the positions of their 4G modules are obviously different.

At the press conference, China Mobile promised to underwrite 500000 Xiaomi notebooks Air 4G version, which will be launched in January 2017, and users can go to relevant channels of China Mobile to buy them. Xiaomi laptop Air 4G 12.5 sells for 4699 yuan, and Xiaomi laptop Air 4G 13.3 sells for 6999 yuan. It can be seen that the biggest highlight of the two is the mobile 4G module. Compared with the traditional super notebook, which only has WiFi network, the Xiaomi laptop Air 4G version has an additional choice in the way of connecting to the Internet, so that users do not need to receive too slow WiFi network impact when using in hotels, airports and other places. However, according to the feedback from netizens, it seems that the free 4G traffic every month is a bit lame. I hope China Mobile can launch a more reasonable traffic discount package for users. And the sales of these two notebooks will also be directly responsible by China Mobile, which may also involve various preferential packages. We will wait and see.
