After Mr. Lei's microblog conference, Xiaomi 9 arrived as promised, and maintained its consistent price performance characteristics: no 3999, no 3299, just 2999! After reading the price, I believe many engine oils will say that they are really delicious. But before we decide to buy them, we might as well look at some details of Xiaomi 9 that Lei didn't disclose at the press conference.

screen

The screen of Xiaomi 9 is naturally a Samsung AMOLED screen at the FHD+level. It is basically the same screen as Xiaomi MIX 3. The sun screen, night light screen and other technologies will certainly not be absent. Although it supports HDR, Xiaomi does not focus on publicity. The entire parameter table only indicates that HDR can be supported when playing HDR10 videos. It is uncertain whether HDR display can be achieved when using apps such as Netflix and YouTube.

In addition, what was mentioned in the press conference passed the VDE low blue light eye protection certification of the German Institute of Electrical Engineers. This is because the Samsung AMOLED screen used has passed the certification, just like the one plus 6T Samsung AMOLED screen used next door. From this point of view, it is not sure whether the Xiaomi 9 AMOLED uses DC dimming. It may still be the original PWM dimming, which needs to be confirmed by the real machine.

SoC characteristics

Xiaomi 9 is known as the world's first Snapdragon 855, but in fact, Lenovo's Z5 Pro GT has been used for mass production models before (It's just that you can't buy it) In fact, the earlier released machines also include the Ruoyu folding screen machine, which has been involved in a war of words recently. In any case, Xiaomi 9 is the first model of Snapdragon 855, but we need to remind you that Xiaomi 9 does not realize all the features of Snapdragon 855.

First, in the network frequency band, Xiaomi 9 is still the same as Xiaomi MIX 3 and Xiaomi 8 in all Netcom 5.0, that is, it does not use Snapdragon 855 to achieve 5G support. In fact, this is understandable. After all, Snapdragon 855 supports 5G and requires an external X50 chip, which will increase the size of the mobile phone. Moreover, domestic and foreign operators have no available trial 5G networks so far, and even if they support 5G, mobile phones cannot use 5G networks. Even the S10 series released by Samsung next door is supplemented by an additional 5G version. The actual main sales force is 4G, just like the Xiaomi9.

However, WiFi only supports 2x2 MIMO, which has not been improved by switching to Snapdragon 855. You should know that Snapdragon 855 is WiFi 6 Ready. It can support up to 8x8 MIMO, and its peak speed is 10Gbps. It is a world away from Snapdragon 845's extreme speed of 867Mbps. (Samsung S10 next door is equipped with WiFi 6 as standard)

camera

In terms of camera, everyone should be familiar with Xiaomi 9, a three camera camera. Although the official parameters are not given, the top transparent and exclusive version is upgraded to a 7P lens, and the aperture is increased to f/1.47, which is slightly different. In addition, it is worth mentioning that Xiaomi 9 has added 4K/60fps in video shooting. Even though Snapdragon 845 has already supported it, only Xiaomi MIX 3 can achieve 4K/60fps.

The front camera only provides one configuration. Unlike Xiaomi 8, which is equipped with 3D structured light on the top configuration version for differentiation, this time all Xiaomi 9 systems are no longer equipped with 3D structured light. However, the full range of offline fingerprint recognition is additionally provided as an alternative, and ordinary face recognition unlocking is not absent.

Battery

In terms of batteries, the premium version of the top configuration is finally different from the Xiaomi 8, without shrinking, and maintains the same 3300mAh battery as the ordinary version. It's a good thing to upgrade the wireless fast charge, but Xiaomi 9 doesn't have the standard wireless charger like MIX 3, but needs to purchase another one. The standard 27W fast charge is commendable compared with the "five blessings and one security" of Apple next door.

MIUI 10

There is no surprise in the system part. It is MIUI 10, of course. But unlike in the past, this time Xiaomi clearly pointed out in the parameters that it supports "MI Turbo" and "Game Turbo". From the adjective, it is obviously benchmarking Huawei/Glory, and even the usage is simulated for 18 months (laugh).

But compared with these XX Turbo, what is more surprising for Xiaomi this time is that on the day of the press conference, the stable version of the kernel of Xiaomi 9 was opened on Github, which is very fast. This speed is not even better than that of Xiaomi 9, which is famous for being friendly to developers. The open source of Xiaomi 9 is very sincere. With the official unlocking, we believe that the playability of Xiaomi 9 is worth looking forward to.
