With the launch of the new Snapdragon 8，Major manufacturers have configured this new SoC into their flagship machines，Hope that their products can become "training dragon masters"，Standing proudly at the top of Android。But for a "big piece" that's not cheap like a mobile phone，I believe that most people will face the problem of choice。

而小米12 Pro和iQOO 9 Pro作為兩大廠商最新的頂配旗艦，It is even more confusing because of the similar price.。as a flagship product，They are adjusted by their respective manufacturers，Outstanding in every way，But if you look closely at the picture below，You will find that there are still some differences，And these differences may influence your buying decision。so today，This article will explain the difference between the two mobile phones，Let you pick the phone that really suits you。

overall design：two styles，Diverse audience

Mi 12 Pro and iQOO 9 Pro are all products with mature design，in perception、In terms of touch and grip, it has achieved the high level of flagship mobile phones。so，able to distinguish between the two overall designs，All that's left is the look and feel and the actual user experience。

overall style，Xiaomi Mi 12 Pro will appear relatively traditional，For example, the overall rounded lines of the fuselage and the blue without special texture、black、Three regular colors of purple。The only distinctive feature is the "wild green" color scheme made of plain leather.。In general，The appearance of Xiaomi Mi 12 Pro is still conservative，This look is for everyone，Nothing can go wrong，But there is also a lack of "new ideas"。

iQOO 9 The overall style of the Pro，It will be more in line with young people's "taste" for the appearance of mobile phones。 The rear shell of the "burning engine" color adopts a special embossing treatment，The Legendary Edition colorway adds racing stripes。 iQOO 9 The overall style of the Pro is not ostentatious，without any superfluous design，Rather, it presents its users with the "beauty of order between square inches"。

When we compare the weight of the plain leather version of the two phones，It can be found，iQOO 9 Pro is not only the body size、The screen size is larger than the Mi 12 Pro，It also has a larger battery than the Mi 12 Pro，And its weight is lighter than Mi 12 Pro's 204g，It can really make us feel that iQOO designers pay attention to user experience。

Performance and Cooling：Multi-dimensional approach is king

The reason why the two phones are compared，Because their core hardware has a certain degree of similarity。 They are all equipped with a new generation of Snapdragon 8 mobile platform、8GB/12GB+LPDDR5 RAM and 256GB+UFS 3.1 ROM。And then to widen the gap，It depends on the manufacturer's individual adjustment and optimization of their respective products.。

on additional performance configuration，iQOO 9 Pro is equipped with an independent display chip Pro，It has two modes: boost frame rate and high frame low power consumption。 The boost frame rate mode can increase the native low frame rate game screen to 120 frames，Let you get a smooth experience beyond the native frame rate;The high frame low power mode can increase the native low frame rate game screen to 90 frames，Let the phone get lower power consumption than the native frame rate。

So how do the two phones perform in the game? Let us tell you the answer with actual testing。 The author selected "Glory of the King"、"Genshin Impact" two popular games are tested。

Through the author's 10-minute "Honor of Kings" test on both mobile phones，we can see iQOO 9 The frame rate of the Pro is up to 118.3，The Xiaomi Mi 12 Pro dropped frames due to down-conversion.，Cause it's frame rate is only 106.4FPS。

When the full picture quality of "Yuan Shen" is turned on，In a 10-minute game test，iQOO 9 Neither the Pro experienced particularly large framerate fluctuations，Its average frame rate can also be as high as 57.3；The Xiaomi Mi 12 Pro not only has a large frame rate fluctuation range，48.8The frame rate is also much lower than iQOO 9 Pro's 57.3FPS。

when i put iQOO 9 After the Pro turns on the frame rate boost mode (frame insertion)，Although the number of frames recorded by PerfDog has dropped，But the actual frame rate has been increased to 90FPS (when switching pages，due to frame insertion，frame rate fluctuations)，Not only does the experience make me feel smoother，At the same time in the fierce battle scene，It will also be compared to when frame insertion is not turned on，provide me with more stability、game state without lag。

want to play games，Good heat dissipation is also indispensable。 According to official data，iQOO 9 The area of ​​the VC vaporizing plate on the Pro is as high as 3923 square millimeters，Far more than the 2900 square mm VC vapor chamber equipped with Mi 12 Pro。

As the saying goes，"One inch，One inch strong"，then iQOO 9 Pro should have an advantage in cooling，Next let's test。 at the same room temperature，The author conducted a 30-minute "Genshin Impact" test on both mobile phones at the same time，The result is as follows：

After testing, we can see that，iQOO 9 The maximum temperature of the Pro's body has increased from 31.0°C at the beginning to 37.8°C，Whether it's a mere 6.8°C increase or a 37.8°C maximum temperature performance is excellent，throughout the game，I only feel iQOO 9 The body of the Pro is a little hot，It won't affect my operation too much;The maximum temperature of the Xiaomi Mi 12 Pro has increased from 32.7°C at the beginning to 42.0°C， Whether it's an increase of 9.3°C or a maximum temperature of 42.0°C，For my actual operation，already have some impact.。

03Charging and battery life：120W fast charge，different speed?

for flagship，Extremely fast charging and strong battery life are definitely essential，Mi 12 Pro and iQOO 9 Pros are equipped with 120W fast charging，And iQOO 9 The charger equipped with the Pro is only about 135g，Dimensions are 61×52.5×29mm，Both the weight and the volume are smaller than the standard charger of the Xiaomi Mi 12 Pro。

According to official data from the two，Mi 12 Pro in fast mode，Use original charger，Fully charged in as little as 18 minutes;iQOO 9 Pro using the original charger (iQOO's first 120W GaN charger)，Fully charged in as little as 19 minutes。 (The Mi 12 Pro battery capacity is 4600mAh，iQOO 9 The battery capacity of the Pro is 4700mAh)

This is official data，So are they actually charging that fast? Next, let's talk with measured data：

From the above figure we can see that，Xiaomi Mi 12 Pro with the original charger，Charge with Fast Mode，It actually takes 25 minutes to fully charge，Such a charging speed is for 120W fast charging，It's not really enough;And iQOO 9 It only takes 17 minutes for the Pro to fully charge the large 4700mAh battery，The speed also exceeds the official data，This result can be said to be quite good。

With fast charge，Naturally, it has to be equipped with a powerful battery，Next let's see how the actual battery life of these two large batteries is。 In order to fully reflect the battery life of the two mobile phones，I tested them for five hours with the ZOL battery life model。

Before the test starts，First charge your phone to 100%，Adjust screen brightness to adaptive，Phone volume set to 50%，Full use of WiFi network，turn off bluetooth、position，Enable Smart Resolution Switching，Enable 120Hz high refresh rate mode。

The test time is 5 hours，The purpose of the test is to compare the battery life of heavy mobile phone users.，as follows：

The following are the test results：

From the above figure we can see that，Mi 12 Pro and iQOO 9 The Pro's performance in terms of battery life can be said to be indistinguishable，Both after 5 hours of heavy use，Still about half of the battery left，It can fully meet our normal daily use needs，It is not difficult to do one charge a day。

imaging system：Almighty Warrior vs Diverse Play

in imaging，We can see from the parameters，Xiaomi Mi 12 Pro is indeed an "all-round warrior"，Not only does it achieve a 50-megapixel triple main camera in the rear imaging system，The front is also equipped with a 3200-pixel high-definition camera。

But if we take a closer look at the hardware they are equipped with, we can see that，iQOO 9 Pro not only debuted with a new generation of sensor GN5，It also brings a 150° fisheye ultra-wide-angle main lens mainly used in sports cameras，make iQOO 9 Pro has more creative gameplay。

So let's take a look at the official proofs of the two：

From the proofs we can see that，Both phones perform very well，Whether it is a galloping horse or a brightly lit "Night Shanghai", Xiaomi Mi 12 Pro can easily hold it；And iQOO 9 The fisheye mode owned by Pro also provides us with a new characteristic gameplay。

If you want to photograph fast moving objects，Then the Xiaomi Mi 12 Pro under the blessing of CyberFocus all things tracking technology，is a good choice;If you want to create more diverse photos、video，Then have a "BUFF filter"、Constant Horizon 2.0、iQOO in fisheye mode 9 Pro is your best choice。

final choice：Mi 12 Pro is fine，iQOO 9 Pro more yuan

generally，The comparison and recommendation of similar models will be concluded with "different from person to person"。Because the models involved in the comparison have their own strengths，Where you need someone to perform well，who is your choice，Xiaomi 12 Pro and iQOO today 9 Pro's matchup is the same。But this "different from person to person" is not because the two phones have their own strengths，But because the functions are very comprehensive，Which type of user group is the two mobile phones more suitable for?。

Xiaomi Mi 12 Pro is very balanced in all aspects，It belongs to the model of "no one can go wrong when buying it"；And if you're after a trendy look、"One step ahead" charging speed、Further game performance and more diverse photography gameplay，then iQOO 9 Pro is a good choice。So these two new flagships，Which one is more in line with your "taste"?
