Xiaomi MIX Fold usage experience：Expand it, it’s the tablet, it’s the phone
——Inner screen panel source exploration
Xiaomi has not clearly announced the internal panel supplier of Xiaomi MIX Fold，We can observe under a microscope that its pixel points show a "pearl" arrangement of drill-like rows，This feature is obviously directed at Huaxing Optoelectronics。This is not the first time Xiaomi has adopted a non-Samsung screen，Previous Xiaomi 10、Xiaomi 11 Youth Edition is available。
Whether it is the close connection between Huawei flagship and BOE before，It is also a combination of Xiaomi's large number of models and Huaxing Optoelectronics，Long-term market feedback and practice have proved that domestic screen panels are useful，This time is no exception。Even add 2K resolution and primary color screens.，In fact, the screen quality is not inferior to that of overseas suppliers' panels。
——Why does Xiaomi choose the internal discount plan?
Let's talk about our common mobile phones first，Even if the model with a high curvature flexible screen appears, it will not affect the normal display effect after scratches.，Because the scratches are actually on the outer glass cover，It does not affect continued use。The folding screen of the folding screen mobile phone is very thin，If there are scratches and many bendings, the marks may become larger and larger.。
to this end，Usually, the inner screen of the foldable screen will be covered with a protective film-like cover.，This cover is very immature in the early days，If you bending too many times, you will most likely fall off。So later there was a cover made of PI material or even CPI material.，Samsung has even developed UTG ultra-thin glass，But it can't stop aging、Low hardness、Old problems that are easy to scratch。
Existing extrusion schemes mean more scratches and creases，The inward folding scheme means relatively fewer scratches and creases，It is obvious that the internal folding solution is more advantageous，This may be the reason why Xiaomi MIX FOLD determines the internal folding scheme as its basic form。
Whether it is past or present，Whether it is folded inside or outside，All folding screen models that are mass-produced and on-market have folding marks。This is related to the number of folds，The longer a machine is used, the more obvious the creases will be.。
From actual experience，Xiaomi MIX FOLD also cannot completely eliminate the creases，However, it basically does not affect daily usage experience，In addition, its hinge does not support hovering。
——Giant screen gameplay
Compared to Galaxy Z Flip、"Flip phones" like Moto Razr，The shape of Xiaomi MIX FOLD is more like a foldable flat plate，Therefore, the gameplay based on this giant screen is also a highlight of Xiaomi MIX FOLD。
First of all, the excellent audio and video game experience brought by the giant screen，This is undoubtedly the most distinctive Xiaomi MIX FOLD as a folding screen、The most prominent feature - an 8.01-inch true full screen，Its sensory impact is most obvious when the screen lights up。
And the mobile phone screen is not like a TV，Big is the first element，Screen quality is also very important。This 8-inch giant screen has a 2K resolution at the same time、AMOLED primary color screen in P3 color gamut，387The ppi also reaches retinal level fine，Based on such a screen，With Harman Katon four speakers，Whether you watch TV series or play games，All can bring excellent experience。
The way to play the office scene is another battlefield outside of audio and video entertainment，After all, it is very difficult to read files on traditional mobile phones，The giant screen shape of the folding screen can bring about subversive changes，After all, this inner screen is more than 8 inches，Comparable to some tablets，A very good reading experience。
have to be aware of is，If a lot of file editing is required，Then Windows devices are definitely more efficient，No need to consider folding screen devices at all。Xiaomi MIX FOLD's office gameplay is aimed at managers or bosses whose main office content is "reviewing"，On the one hand, it is more portable than tablets，On the other hand, after being expanded, you can provide a flat view。
In addition to better reading files，If you want to use your mobile phone to achieve light office gameplay，In fact, a lot of adaptations are required at the software layer.。And this，Xiaomi MIX FOLD is doing quite well：Split Screen、Parallel windows、Double screen drag、Multi-picture transmission and other gameplays are all added，Let this large screen of MIX FOLD be used for the best。
Since the Xiaomi MIX FOLD we have experienced uses early firmware，Still stuck in MIUI12 version (it will be updated to MIUI later 12.5，That's the complete body)，So many functions are not yet adaptable，For example, PC mode on hand。This mode，We have the opportunity to experience it in detail later。
performance："Genshin Impact" runs for a long time and full frame! This heat dissipation has been a long experience
As Xiaomi's most expensive mobile phone，Xiaomi MIX FOLD performance materials are full of materials - Snapdragon 888 5G mobile platform + 12GB/16GB LPDDR5 high-speed memory + 256GB/512GB UFS 3.1 high-speed storage，Even the "entrepreneurial model" uses super large memory directly，It can be seen that the material is so powerful。
——Practical test of game cooling
It is worth mentioning that，The folding screen phone itself has a huge cooling area due to the larger body space.，Benefits in cooling，Xiaomi MIX FOLD has also made further heat dissipation and stacking materials based on this。
Xiaomi uses parallel dual stereoscopic cooling system and "micro-airbag" cooling mechanism for MIX FOLD。Simply put, a cooling system is designed on both the left and right parts of the mobile phone.，At the same time, it also connects both，A complete heat dissipation system。
Specifically，Xiaomi MIX Fold has almost all the passive cooling solutions you can see so far，Including VC liquid cooling + thermal gel + multi-layer graphite sheet + material-grade bending-resistant graphite sheet，There is also a whole piece of copper foil under the screen to dissipate heat，The total heat dissipation area reached 22583.7mm²， Almost twice as high as Xiaomi 11，The cooling capacity can be imagined。
Since the component stacking on the left and right sides of the Xiaomi MIX FOLD with a folding screen shape is not completely balanced and consistent，The motherboard and the SoC are located on the side of the body.。
In order to solve the problem of unbalanced heat dissipation，In case of limited stacking space，Xiaomi MIX FOLD adds heat transfer tunnel，Then connect the parallel heat dissipation systems on both sides of the shaft。In this way, the heat on one side of the SoC can be transmitted to the other side with a lower heat dissipation pressure through this channel，This achieves more balanced and stronger heat dissipation capabilities。
The specific solution is a heat dissipation structure that has the "micro-airbag" bionic knuckle skin through graphite sintering technology and coating technology improvement.，The bending-resistant graphite sheet created thus has undergone 180-degree bends of 200,000 times，Thermal performance will only drop by 3%-5%。
In order to "squeeze" the performance release and heat dissipation capabilities of Xiaomi MIX FOLD，Let's choose one to connect to Android、iOS and PC's open world game "Genshin Impact" to test the phone，As for how "destroying" this game is, you can check out our previous four flagship platforms of "Genshin Impact" to understand.。
Among the following tests，We lowered the Xiaomi MIX FOLD to 50% brightness、Use silently、The picture quality is "extremely high quality"，Turn off motion blur，The room temperature was around 25℃ during the test。
From the actual game test，10Minutes of game，Xiaomi MIX FOLD average frame rate can reach about 59.6 frames，Basically close to 60 frames full frame，The CPU core temperature reaches up to 52℃，The maximum temperature position on the surface of the fuselage is near the SoC，40.8 ℃，This is the best Snapdragon 888 model for "Genshin Impact" game experience that I have seen。
——Run points
Results included in Driver Home List，Snapdragon 865 model can reach a single core 918、Multi-core 3386。The Snapdragon 888 equipped with Xiaomi MIX FOLD is about 22% higher than that of each、1.6％，Comply with the performance of normal Snapdragon 888 models。
GFXbench testing，The Snapdragon 888 equipped with Xiaomi MIX FOLD reached 158FPS in Manhattan 3.0 1080p off-screen score；Aztec Ruins Vulkan 1080p/regular off-screen score is 78FPS，Compared with the scores of the above two test sub-items, the scores of Snapdragon 865 are about 33% respectively.、50％，Normal performance of Snapdragon 888 model。
