For ordinary consumers，I guess not many people know，The world's first mass-produced foldable phone actually uses an external folding design。However, due to the technology of the time、immaturity in design，It was quickly replaced by a more durable fold-in design。Huawei, the representative brand of folding design, launched the Mate X、After two generations of Mate Xs，Also start changing routes，Inward fold design on Huawei Mate X2。Just when everyone thought that the in-folding design would unify the folding screen market，HuaweiBut last week brought us the latest product of its outer folding series - Huawei Mate Xs 2 。
In this era when in-fold design has become mainstream，Why Huawei is bucking the trend，Choose to launch an external folding flagship? through a week of experience，Below is my feeling。
design：A large-screen experience that takes into account thinness and flatness
For folding screen phones，There are three points of concern in appearance：weight、Crease and Texture。Then let's take a look Huawei Mate Xs 2 What are the advantages and disadvantages of the performance in these three aspects compared with a number of in-fold flagships?。
In Huawei's promotion，One of the main advantages of the fold-out design is that it is thin and light。This is true in my actual experience，Although the weight of 255g and the thickness of 11.1mm after folding are still thicker than ordinary candy bar phones，But the Mate Xs 2 is definitely the thinnest and lightest among the current horizontal folding screen phones.。
when you expand the screen，Due to the change in the center of gravity，The lightness in the hand will become more obvious。At the same time, the thickness of the screen side is 5.4mm after unfolding，Makes people feel as if they are holding a screen，rather than a full-featured phone。

can achieve such a thin effect，It is inseparable from the outward folded form it adopts。in folded form，Mobile phone can save a screen，Naturally thinner。
besides，To further reduce the weight of the fuselage， Huawei Mate Xs 2 Many innovations have also been made in the material，For example, the back cover is made of ultra-light glass fiber commonly used in the aviation field.，Aerospace-grade titanium is used in the screen support structure，The hinge also uses ultra-light and super-strength steel with Huawei's self-developed formula。With these ultra-light innovative materials，While achieving the overall weight reduction of the fuselage，Has the characteristics of high strength and high toughness，lighter and more reliable。
For folding screen phones，Another important point we are concerned about is the crease problem of the screen。 Huawei Mate Xs 2 採用了升級的雙旋鷹翼鉸鏈設計，Make the screen flatter，Officials say its flatness is 70% higher than the previous generation Huawei Mate X s。in my actual experience，Whether folded or unfolded，It is difficult to see the existence of screen creases，And in the process of folding the screen，There will be no raised creases。At the same time, the sealing of the outside of the hinge is also very good.，Avoid the possibility of debris intrusion。
Huawei Mate Xs unfolded 2，Has a 7.8-inch ultra-clear foldable screen，Display scale is 8:7.1；in folded state，華為Mate Xs 2擁有6. 5英寸屏幕，Display scale is 19:9，normal screen ratio，Make the Mate Xs 2 feel comfortable even in the folded state。
And 424 ppi ultra-high pixel density，It also allows users to obtain a more refined visual experience。With 1.07 billion colors and P3 wide color gamut color management，Huawei Mate Xs 2 can provide users with a more immersive visual experience and a more shocking visual experience。This screen supports a refresh rate of up to 120Hz and an ultra-high touch sampling rate of 300Hz，Provide users with a smoother visual and touch experience。besides，This screen also uses 1440Hz high frequency PWM dimming，More eye protection than ordinary OLED screens。
For a fold-out design that exposes the screen，The durability of the screen itself is very important。To solve this problem，Huawei Mate Xs 2 adopts the industry's first composite reinforced structure screen，and high-performance materials，Effectively absorb and buffer external forces，The design is similar to the car crash structure，2.5 times anti-drop、2.8 times more impact resistant and 1.4 times more crush resistant than the previous generation。However, since the screen itself is not made of glass，Still need to be careful in daily use。Mate Xs 2 also comes with a protective case，It is recommended to bring it with you in daily use。
As a million-dollar flagship，The use texture of folding screen mobile phones is naturally also worthy of attention，And the most representative of them is the opening and closing feel of the screen.。Different from the same opening and closing feel of the inner folded mobile phone。The screen of Huawei Mate Xs 2 is significantly more damped when unfolded than when closed。At the same time, it adopts a buckle design to ensure that the screen is closed.，Expand the screen if needed，You have to press the button on the back of the fuselage to do it，Slightly inconvenient to operate。
Finally, let's take a look at some details on the appearance， Huawei Mate Xs 2 With side fingerprint design，The recognition speed is good。Stereo dual speakers are arranged on the upper and lower sides，It has a double airtight large sound cavity，Create a three-dimensional surround sound field，And equipped with a new AI sound engine，Achieving a more balanced effect in audio width and loudness。
Fold-out design and hinges、Under the optimization of materials and other aspects，Huawei Mate Xs 2 makes the horizontal folding screen mobile phone achieve a lightweight and unburdened experience for the first time。However, it is slightly inferior to the current inward folding flagship in terms of opening and closing operation and feel.，It will also take time to verify how the exposed screen performs in terms of durability。
experience：Sex can be used，Better optimization
With a big screen，How to use the experience has naturally become the focus of everyone's attention，After all, if you want to take full advantage of the big screen，System-level optimization is essential。As one of the manufacturers of folding screen mobile phones，Huawei's performance in this regard is naturally not bad，Let's take a look。
The first is the system itself，Due to the folded design，Huawei Mate Xs 2 itself has only one screen，Therefore, whether the system can achieve a smooth transition between the folded and unfolded states has become an important issue.。
In order to provide a more integrated user experience，Huawei Mate Xs 2 adopts new folding visual and dynamic effects at the system level，At the same time built-in smart folding live wallpaper，The picture can be changed as the screen opens and closes，Make the mobile desktop more flexible。Let the mobile phone truly be opened and closed，The screen content flows flexibly。
Split-screen function is standard for folding screen phones，It can indeed greatly improve work efficiency。But deep entry and cumbersome operation，It is difficult for many users to remember to use these functions。Huawei Mate Xs 2 has made a lot of efforts in this regard，Split screen with one swipe、small window、full screen、Collapse and other multiple operations，Make it easier for users to operate，Further leverage the efficiency advantages of large screens。
For folding screen phones，Another major pain point in use is application adaptation，Many Android apps are simply stretched under the big screen，Displays even less content than a traditional candy bar phone，This is undoubtedly a serious waste of the big screen。To solve this problem，Huawei unveils adaptive UI engine，Obtain original layout information through self-learning，Re-optimized layout for large screen display，finer layout，More suitable for reading habits of large screen users。
According to the actual test, it can be seen that，With the help of an adaptive UI engine，App can display more content on the big screen，Improve the reading efficiency of users。According to official data provided by Huawei，At present, Huawei Mate Xs 2 has achieved 100% large-screen adaptation in Top 300 applications，Top 2000 applications have achieved 90% large-screen adaptation，On Huawei Mate Xs 2，Users can get a better large-screen experience。
Finally, let's talk about performance，Due to supply constraints，Huawei Mate Xs 2 still uses the 4G version of the Snapdragon 888 processor，However, its performance is sufficient for daily use.。To actually test its performance，We tested it directly with Genshin Impact，Under the setting of very high quality + 60 frames，The average frame rate of Huawei Mate Xs 2 is 46.6 fps。The frame rate curve is relatively flat，The actual game experience has no obvious lag，Reached the average level of the Snapdragon 888 processor。
Overall，Huawei Mate Xs 2 provides better performance while，Focus on optimizing the user experience。By further simplifying the operation logic of small windows and split screens，Make it easier for users to use。The innovative adaptive UI engine solves the big problem of App optimization, which plagues folding screen phones，Helping the big screen take productivity to the next level。

on an ultra-wide-angle lens，Color adjustment maintains the same style as the main camera，After turning on AI enhancements，relatively bright colors。In the face of some relatively large scenery environment and tall buildings，The Mate Xs 2's ultra-wide-angle lens produces spectacular proofs，very practical。
in telephoto proofs，Thanks to its telephoto lens，The sample of Mate Xs 2 still guarantees good resolution at 3.5X zoom，The description of the exterior details of the building is in place，Architectural details in dark areas under the eaves are still accurately rendered。
night view，The Mate Xs 2 takes an overall good photo, even in low light。The overall picture does not blindly increase the brightness，Instead, it takes care of the overall look and feel of the picture.，Details in highlights and shadows are preserved，The amount of noise is also well controlled，looks clean，Compared with other folding screen mobile phones, the advantages are obvious。
In addition to excellent image quality，Huawei Mate Xs 2 also supports more interesting gameplay。For example, the mirroring smart shooting function allows the subject to preview the shooting picture.。Open the camera in the folded state，Click the function button to turn on the mirroring smart shooting function。At this time, the main screen and the secondary screen can display the viewfinder screen at the same time，Both the photographer and the subject can preview the shooting effect，No longer have to worry about your girlfriend rejecting you and taking pictures is not good。
Passers-by that you don't want to see mixed in in the photos you took? Huawei Mate Xs 2 integrates a new generation of AI elimination function in the Gallery App，when editing pictures，After selecting the "Erase" function，Just click to intelligently identify the selected object and eliminate it。AI image processing technology will intelligently identify the background and color、Fusion of contours，no need for deepPSskill，Simple and easy。

Battery life and fast charging：4600mAh battery + 66W fast charge，Greatly relieves battery life anxiety
Due to the design of a large screen，The battery life of Huawei Mate Xs 2 has also attracted the attention of many friends，To solve the battery life problem，Mate Xs 2 is equipped with 4600mAh battery and 66W super fast charge。Next, let's take a look at its strength in terms of battery life and charging.。
battery life，We tested the phone using ZOL's 5-hour heavy battery life model of a foldable phone，When testing，Phone system volume and screen brightness are both set to 50%，Wi-Fi and Bluetooth on，Enable Smart Refresh Rate。The test content includes 30 minutes of 30fps 1080P video recording、451080P video playback at station B in minutes、50Minute Douyin Video Play、60Minute high frame mode "King of Glory"、45Minutes to brush the information flow on Weibo、30Minutes Taobao homepage browsing and 50 minutes QQ voice chat。
From the results，Mate Xs 2 has 37% battery remaining after 5 hours of testing，Battery life is mediocre。If you are a heavy mobile phone user，Mate Xs 2 may need you to increase the frequency of charging。
And speaking of charging，Huawei equipped Mate Xs 2 with 66W super fast charge，It belongs to the first echelon of current folding screen mobile phones in terms of power，So how about the actual charging speed of the Mate Xs 2? Let's see by testing。
Before the test, I first completely drained the battery，Connect Huawei 66W Charger，Start timing when the phone is turned on。According to the measured data，at the current room temperature，Huawei Mate Xs 2 charges 31% in 10 minutes，30Charged to 85% in minutes，This result can be regarded as an excellent level in the current folding screen mobile phone。It is worth noting that，If you want faster charging speed，Need to keep phone unfolded，This helps the phone cool down。
Overall， Huawei Mate Xs 2 The overall performance in terms of battery life and fast charging is acceptable，Daily light use can basically guarantee one charge a day，In the case of heavy use, it can also quickly recover blood through 66W super fast charge。I believe that under the blessing of 4600mAh battery and 66W super fast charge，The user's battery life anxiety can be alleviated。
Finished reading Huawei Mate Xs 2 After using performance in various aspects，I think I can come and try to answer the question in the title。Inward fold design has become mainstream today，Huawei's Mate Xs 2 isn't just different for the sake of being different，quite the opposite，Huawei uses such a "non-mainstream" design with external folding，Solved one of the biggest pain points of current folding screen mobile phones-heavy。Its weight of 255g is very close to the flagship candy bar phone，So that users do not need to choose between large screen and thin and light。
besides，The dual-rotor eagle-wing hinge design and composite reinforcement structure make the screen crease lighter and more durable，Adaptive UI engine allows large screens to display more information，It can be said that Huawei is in the Mate Xs 2 It is indeed optimized for the pain points of current folding screen mobile phones，Bring a better user experience to users。under the constraints of supply，Huawei has not given up on the mobile phone market，Instead, dig deeper into user pain points with limited resources。Believe that with the help of this spirit，Huawei's mobile phone business must be able to persist，Continue to bring better products to users。
