It has been about half a month since the release of the Mi 12 series，At present, the whole network is about the Mi 12 series large cup (Mi 12) and super large cup (Xiaomi 12 Pro) has a lot of content to get started，But it seems difficult to find relevant content about Mi 12 X，And at the press conference，It seems that Xiaomi 12 X is not mentioned much either。Is it really like what netizens said，Is this a product for Xiaomi to clear inventory? Xiaomi 12 Is X really not worth buying? Let me introduce Xiaomi to you 12 X in two weeks of experience，What are the advantages and disadvantages?
Curved frame plus hyperbolic glass plus the weight of the whole machine is 176g，Mi 12 X brought me a lot of surprises when I first got it。The curved frame does not have the sharp feel of the right-angled frame，Fits the palm better，The overall feel is quite round。
The back glass adopts the recently very popular AG glass process，This time I chose the purple color scheme，There will be a color gradient effect under the light；And although there is no "fine flash" starlight on Mi 12，But relatively more stable、Atmospheric。for me personally，I'm still quite disgusted with the small decorations in the bells and whistles.。
And to the screen，Mi 12 X is equipped with the same model as Mi 12 6.28 inch 12bit super visual screen，Supplemented by 120Hz high brush，The experience during use is quite good。What impresses me about this screen is the degree of color reproduction，However, it cannot be reflected in the evaluation，Interested friends suggest going to a nearby store for offline experience。
In fact, when I first saw the appearance of the Mi 12 series,，i can't accept。 Because it really looks like the design of Xiaomi civi，Missing the previous maturity of the Xiaomi digital series、Steady temperament。But after two weeks of experience，Personally, I am quite sure about the design of Mi 12 X。 and it's worth noting that，On such a small-screen flagship，Large-capacity battery and fast charging are not absent，At the same time, the iconic infrared remote control and X-axis linear motor of the Xiaomi digital series have also been retained.，The only regret should be Xiaomi 12 X does not support wireless charging。
star camera sensor，Darkness still shines
Although Mi 12 X cannot use the same IMX707 sensor of Mi 12 Pro in the imaging system，But IMX766 is still a flagship sensor，After more than a year of polishing，supplemented by”Xiaomi Imaging Brain”and”Night Owl Algorithm 2.0″blessing，Makes the image performance of Mi 12 X quite good。
Let's analyze directly with sample comparison，The first is the performance of the main camera in the daylight environment。 Although it is cloudy outside，But the overall picture in the proofs is relatively transparent。And the color saturation of the picture is also relatively high，but not too flamboyant，It's a more pleasant type，Our second proof can be well reflected。certainly，There are also deficiencies in the proofs of Mi 12 X，For example, there will be more obvious traces of smearing on the details of the dark part。
The following is a set of proofs of the main camera and ultra-wide-angle in a dark light environment。It can be seen in the two proofs，The color of the sky is blue，This should be due to the adjustment of the algorithm to generate blue，And whether users like it or not is a matter of opinion。
main camera sample，The picture is still pure，The turret part has clear edges and corners under the illumination of the light，Just the right amount of sharpening。In the ultra-wide-angle proofs, although the definition is not as good as the main camera proofs，But there are also remarkable places。For example, in the super wide-angle proofs，There is no obvious distortion problem，There is no obvious noise problem in the picture。
The following is a sample of the night scene of Mi 12 X，Here we take a look at the adjustment of the Xiaomi camera department for this IMX766。First, let's look at these three，It can be seen that the highlights are well suppressed，The screen is not overexposed。Simultaneously，The suppression of noise in the proofs is also excellent，angular parts of the building，part of the sky is transparent。
But in the night scene proofs，There are also works of "rollover"，For example, the following two sets of proofs。
first”General's Mansion”This set of proofs，The performance of Mi 12 X is somewhat unsatisfactory，The writing on the pillar is almost hard to see，And use the iPhone 13 to shoot，The brightness of the photo has been significantly improved。Of course, we are not comparing the 3,000 yuan Mi 12 X with the 5,000 yuan iPhone 13，I just want to explain that there is still room for improvement in the performance of Mi 12 X in night scenes。
The same is also the sample of the following group of Shenwumen in the Forbidden City，Also the iPhone 13 performed slightly better。
Overall，The performance of Mi 12 X in the image part is satisfactory，Especially in the image part of the dark environment，still brilliant，However, if you want to break the wrist with the iPhone 13 series, it may take the efforts of the post-production imaging department。In addition, in terms of operating experience，Mi 12 X compared to the previous generation Mi 11 series，Significant improvement in film forming speed，But until the current MIUI13.0.10.0 stable firmware，Mi 12 X's camera start-up speed will be stuck，And similar problems occur on all Mi 12 series，This may need to be fixed with the upgrade of the MIUI version。
Snapdragon 870 SoC，Still a good flagship core
Snapdragon 870 as processor to be released in early 2021，It is really not enough to put it in the 3000 price range in this time period，So is the performance of Mi 12 X really that bad? Is Xiaomi really dealing with inventory? Obviously not，Snapdragon 870 + LPDDR5 + The performance combination of UFS 3.1 can still stand at the head of the second gradient of performance。
Let's take a look at Mi 12 X on AnTuTu、Geekbench 5、3The running scores of the three DMark test software。You can see whether it is single-core or multi-core results，Mi 12 X's performance is not bad，But in subsequent experience，Mi 12 X performance seems to have some glitches。
In subsequent performance tests，We selected two games, "Glory of the King" and "Yuan Shen"，The first is the part of "Glory of the King"，What we choose is the image setting that is directly stretched to high-definition quality + ultra-high resolution + extremely high frame rate，The result is as follows。
It should be noted，The part of the first 60 frames is in the hero selection and the loading interface of the game，MIUI is locked at 60 fps by default。But later, after entering the game，120The frame of the game screen only persisted for about 2 minutes，The frame rate is locked at around 90-100 frames。Although it does not affect the fluency of the game，But there are still some uncomfortable，As expected, the same situation appeared in the subsequent "Original God" test。
Due to the strict requirements of "Yuan Shen" itself on the performance of mobile phones，So in the test, just set the screen configuration to the preset”middle”quality，And increase the frame rate cap to 60 frames，As a result, the game is almost in a state of around 45 frames throughout the game。
Then we adjusted the frame rate to the preset 30 frames，Finally, there is no longer the dilemma of lock screen frame drop。But when you get used to the smooth game experience，30The frame rate of the game screen is really lagging。But if the pursuit of game stability，Or honestly choose the default configuration。
overall experience，The performance of Mi 12 X is completely sufficient to cope with the mainstream games and daily use experience on the market today.，However, the game's down-frequency lock frame may be a part of MIUI that needs to be optimized in the future.。If you are not a heavy gamer，Mi 12 X can fully meet your needs in terms of performance。
4500mAh+67W，Small body but big energy
battery life，A massive 4500mAh battery is crammed into the Mi 12 X's compact body，Even if it is placed in a flagship product with a large screen，That's a pretty big battery.。So is this 4500mAh battery resistant to manufacturing? Let's take a look at a set of 5-hour battery life tests。
We selected the 7 most common scenarios：
- Watch iQIYI video：Play 45 minutes of 1080P resolution video in full screen;
- Douyin short video：Swipe the video stream in the video interface，50 minutes in total。
- QQ chat：20minute text chat;1510 minutes voice chat and 15 minutes video chat，50 minutes in total。
- Brush Weibo：Enter the list page and slide for 45 minutes。
- camera recording：Record 1080P 30fps video，Record 15 minutes;The default main camera takes pictures for 15 minutes，30 minutes in total。
- Play King of Glory：Combat Mode "Actual Combat Confrontation"、Map of Kings Canyon 5V5，Test 60 minutes。
- swipe mobile phone taobao：Enter Taobao homepage and slide，20 minutes in total。
The result is as follows：
can be seen，The 4500mAh battery of Mi 12 X is sure to be durable，After 5 hours of simulated battery life test，really good。 And in my last two weeks of using，Basically a daily charge，And based on 67W wired fast charging，also very fast，Wired fast charging based on Mi 12 X 67W，After testing, it takes about 35 minutes from 0-100%，Basically, you can quickly return blood by charging at any time。
Overall，The small body of Mi 12 X is equipped with a large 4500mAh battery and 67W wired flash charging，The experience in battery life and fast charging is quite good，The only regret is that Mi 12 X does not support unlimited charging，For users who like to keep their mobile phones on the wireless charger at hand，not very friendly。
I personally think the Mi 12 X 3199 The starting price of CNY is for ordinary users，Consider other Snapdragon 888 flagships in the price range of one or two thousand currently on the market，But if you are the current user group of small-screen mobile phones or Xiaomi fans，Then Mi 12 X is worth starting。
Although the two-week experience cannot fully understand the advantages and disadvantages of Mi 12 X，But it can be a simple reference for everyone before purchasing。I have also experienced other products in the Mi 12 series，What I have to admit is that compared to the Mi 11 series this time, Xiaomi，a lot more cautious，One is the design language，The second is MIUI 13 experience，Although there are still bugs，But compared to last year, there is a significant improvement。
