Xiaomi Mi Mix 3 5G Version Review: 2019 Best Value 5G Smartphone

0

as early as the MWC 2019 conference, Xiaomi released its first 5G mobile phone – Xiaomi Mi MIX 3 5G, which is also one of the first 5G mobile phones in the world. We all know that Xiaomi Mi MIX 3 is a mature commercial product, and Xiaomi Mi  MIX 3 5G is also a real 5G commercial product.

Since the Xiaomi Mi MIX 3 5G has not been sold in China for a long time after the release, it is basically placed in the European market, so we got this mobile phone after a long time after the release, followed by the Xiaomi Mi MIX 3 5G. Some experiences are shared with you.

Design & Buy

Xiaomi Mi MIX 3 5G maintains the overall design and specifications of Xiaomi Mi MIX 3, such as slide full-screen design, 6.39-inch FHD+ AMOLED screen, 93.4% screen ratio and other iconic elements without any changes. Of course, the post-installation method that prevailed in the millet MIX3 era is also preserved.

Photographing, consistent with the previous 4G version of the Xiaomi Mi MIX 3, front 24MP + 2MP double camera, rear 12MP wide-angle (Sony IMX363) + 12MP telephotos double camera, support four-axis optical image stabilization.

However, in fact, the two are basically the same as the shape, the photo, etc., in fact, two different models, especially the Xiaomi Mi MIX 3 5G of the processor upgraded from Snapdragon 845 to Snapdragon 855, and joined The Snapdragon X50 independent baseband realizes support for 5G, and naturally there are a lot of reconstructions and changes to the inside of the fuselage, especially the motherboard.

Due to the high power consumption of 5G and the use of the mainstream external baseband solution, the battery capacity of Xiaomi Mi MIX 3 5G has also increased from 3300mAh to 3800mAh to ensure the endurance.

5G experience

As before when testing other 5G models, we went to the Unicom Road Business Office in Unicom, Zhengzhou.

Before the start of the 5G related function experience, the author will briefly introduce the millet MIX3 5G version that we have obtained the same single card single-mode design as a large number of 5G verification machines. The card slot can only be loaded with one SIM card, and only Support NSA networking.

At present, we still do not know whether Xiaomi Mi MIX 3 5G is still possible to be officially launched in the domestic market, and it is not certain that if it is launched, will the National Bank version of Xiaomi Mi MIX 3 5G join the dual-card design.

However, considering the future development trend of the three domestic 5G models that have been sold in China, the dual-card design is still necessary for China.

1, 5G network speed measurement

UI. The speed of the network is the most obvious point that most people can perceive the 5G network, which is the most intuitive upgrade compared to the 4G network. According to public data, in theory, the 5G experience rate is 100 times that of 4G, the peak rate is increased by 20 times, and the delay is reduced to 1/5. In a 4G network, it may take a lot of time to download large files, and in a 5G network environment, the number of seconds is reduced.

This needs to be attributed to the use of millimeter-wave spectrum in 5G networks, and no longer takes the 300 MHz to 3 GHz spectrum used in the first to fourth generation wireless communication technologies. Of course, the latter has properties such as wide coverage and strong penetrability, but the problem of too narrow bandwidth and depletion of resource allocation is very difficult.

By the way, some off-topic, 5G network millimeter-wave antenna beam is narrow, the antenna length is short, it requires a longer period of layout construction for operators, not only large macro base stations, small millimeter wave transmitters also need to follow up and A large number of additions, so in the 5G year, we may have a hard time experiencing the perfect 5G network, and it needs to be fully mature.

Go back to the topic and see how the speed measurement of the Xiaomi Mi MIX 3 5G is under the 5G network. As shown in the figure above, the left is the speed measurement results in the 5G network environment, and the right is the speed measurement results in the 4G network environment. The 5G network of the operator’s business hall used in our test was in the debugging stage for a long time (the author even complained many times), which is extremely unstable and cannot reach the theoretical peak under the 5G network.

Under such unfavorable test conditions, we have seen that the download rate of Xiaomi Mi MIX 3 5G reaches 810Mbps, which is 14 times that of the 4G network, and the upload rate is 5 times that of the latter. According to Xiaomi’s official data, Xiaomi Mi MIX 3 5G has reached the highest download speed of 2Gbps and can download 15 minutes of 1080p full HD video or 26 MP3 music in one second.

According to Xiaomi, Xiaomi set up a 5G pre-research team as early as 2016. In early 2017, it officially launched the 5G mobile phone design. In the same year, it opened the 5G signaling and data link connection under the 6GHz band, and also opened the mmWave millimeter band connection.

2, the actual application experience

speed test (mainstream speed measuring tool) measures the theoretical transmission rate under 5G network, so what is the feeling of actually using the 5G network? We take the experience test of some practical applications.

Downloading applications in a 5G network environment, applications that used to take tens of seconds or more to download can be completed in just a few seconds. In the future, with the further development of mobile storage technology, an App second download can be foreseen. Second install, second open future.

Feel free to pull the progress bar of the online video, almost no buffer in the 5G network environment, the basic instant buffer is completed, almost no card appears.

3, 5G network delay

Compared with 5G and 4G, one of the most remarkable features of the technology is the transmission of ultra-low latency. What is the delay? In our daily life, in daily life, two people talk to each other and the sound information is transmitted to each other. The time of transmission is 140 milliseconds.

The author’s expectation for 5G, in addition to the network transmission rate, is more than its claimed low network delay. Even before, the expected delay for 5G was even a time of 1 millisecond, which was a somewhat imaginative speed. From the actual experience, even with a lower speed of response, our network environment and supporting technologies can’t be done.

Compared to 4G networks, there is no obvious delay reduction. In fact, this level has nothing to do with the terminal manufacturers. At the current NSA networking stage, the user plane transmits through 5G, and the control plane signaling still passes 4G transmission. That is to say, the total delay in the non-independent networking mode is that the 4G control plane signaling delay superimposes the 5G user plane delay, and then superimposes the Internet delay.

Therefore, at the current stage, subject to the operator, the network delay of all 5G mobile phones cannot be significantly improved. We are infinitely expecting that in a somewhat distant future, the SA network will kick off the 4G control plane signaling delay, and the ideal delay of 1 millisecond is possible.

Verdict

2019 is the first year of 5G, and nationwide deployment requires a lot of time. As we said in the text, the biggest problem with 5G popularity is the terminal and the network. There is also the question of whether there is a chicken or an egg first. The terminal may say that there is no network to use, and the network may say that there is no terminal to provide services.

Based on our many and multi-faceted experience records, there is still room for development in both the terminal and the carrier network. At the terminal level, the types and models of existing models launched by Huawei, ZTE, and vivo are still very small, and the range of people covered by the three brands is also very limited. This is a time when we really need one as millet giant companies come in as soon as the volume is cut, it is necessary millet 5G mobile phone brand leveraging more people to join the wave of replacement.

We still don’t know if Xiaomi Mi MIX 3 5G plans to return to the domestic market. If it is willing to return, as long as the National Bank version can solve the single card single-waiting design that is not suitable for the actual situation in China, then the Xiaomi Mi MIX 3 5G is a mature 5G commercial mobile phone.

Aside from the 5G attribute, Xiaomi Mi MIX 3 5G is also an excellent new machine that is different from Xiaomi Mi MIX 3 4G version. As we said before, its SoC was changed from Xiaolong 845 to Xiaolong 855 platform, and the battery was increased from 3300mAh to 3800mAh. The slider design is also unique among all current 5G phones.

In February of this year, Xiaomi Mi MIX 3 5G sold for 599 euros in Europe, about 4560 yuan (at that time, the cost of 5G chips and components was still very high, Lin Bin admitted that millet MIX3 5G version 599 euros basically no profit).

Now, after half a year, although the existence of the national version, the release time, and the price have not been announced, but with the multiple factors such as the decline in component costs, and the rumored millet 9S 5G version on the road, Xiaomi Mi MIX 3 5G does not return Then, once the return is bound to give a surprising price.
