Xiaomi 11 launches Qualcomm flagship processor Snapdragon 888 in the world，Have a top 2K screen、Stronger WiFi performance、Full blood version of LPDDR5 memory、1Ultra-definition main camera with 100 million points、55Fast charging combination of W wired + 50W wireless + 10W reverse charging，More importantly, Xiaomi 11 is thinner，This greatly improves the happiness index of users using their mobile phones。also，Xiaomi 11 is also the first model with a linseed version。
Xiaomi 11 screen size has increased to 6.81 inches，But it's not a big circle，But it's more slender，Brings a smaller body width。So Xiaomi 11 is not more supportive than Xiaomi 10，On the contrary, because the whole machine is lighter，The actual test includes SIM card and screen protective film is 195g，It will be more handy when using one hand。
This screen also uses the new E4 luminous material，Brings 1500nit peak brightness、10-bit color depth display in over 1 billion colors，Resolution rate reached 3200*1400 WQHD+，That is what we often call 2K resolution。Combined with front and rear ambient light sensors and Xiaomi's self-developed screen calibration calculation，Xiaomi 11 has outstanding performance in automatic brightness adjustment and color management。
Xiaomi 11 with four curved surface design is exquisite and extraordinary，The arcs on both sides are not obvious，Not much impact on actual use，It can mainly reduce the visual thickness of the whole machine。The surface area at the border is very narrow，Very small curvature，Maximize and reduce edge picture distortion。
also，Xiaomi 11 also supports 120Hz high refresh rate and touch sampling rate up to 480Hz，It's 4 times the refresh rate，The screen display is smoother、More accurate touch，This improvement is very friendly to mobile game players。It is worth mentioning that，2K resolution、High brush、DC dimming can be started simultaneously on Xiaomi 11，No castration! also，Higher refresh rate and touch sampling rate can make the system echo more timely，Even if you don't enable the high frame rate option，All support four-speed refresh rate self-adjustment adjustment under the 120Hz refresh rate option。
in terms of color，Every screen of Xiaomi 11 has been calibrated before leaving the factory，Supports ultra-high color quasi-primary color screen and 1 billion color display，JNDC≈0.38、ΔE≈0.41。Xiaomi 11 has performed well in all aspects of the screen，Give it a DispalyMate A+ rating。
In terms of image quality，Xiaomi 11 is more than that，A newly added AI master image quality engine，Let Xiaomi 11 display effect be one step closer。AI Master Image Quality Engine can provide a variety of image and video processors，Mainly including super-resolution enhancement (image、Video enhancement，Maximum increase to 1440P)、AI smart scene optimization、Video quality enhancement (HDR enhancement，The picture is more beautiful、Vivid) and dynamic picture compensation (dynamic pins)。in，Super Resolution Enhancement and Dynamic Screen Compensation cannot be turned on at the same time，Because there are some overlaps between the two functions。
It is worth mentioning that，During the use process, we found，Xiaomi 11 has built-in grip sensor on top and bottom，Able to use gyroscope to determine the anti-incorrect touch area，You can judge the holding area without using a point mask，Turn off anti-touch function in non-gravitation area，Normal touch interaction。At the same time, the front of Xiaomi 11 uses a hidden earpiece，Micro-slit sound output holes are used at the edge of the mask，Ensure full screen viewing。
I think the picture and the audio have always been complementary.，So I used a better screen，The sound quality must be improved together。Xiaomi 11 uses stereo dual speakers，The sound quality has been professionally adjusted by Harman Katon，The bottom uses a 1216 ultra-linear speaker unit，The two-in-one speaker on the top form the body sound。
The sound quality and hidden effect of the two-in-one speaker at the top are good，But I still haven't escaped the problem of different voices on both sides。Xiaomi 11 also adjusted the speaker position，So I don't need to hold the camera and play games like Xiaomi 10。
If you want to say that Xiaomi 11 has attracted much attention，There is another reason，That's the effectiveness，This time Xiaomi launched the world's first Qualcomm Snapdragon 888 processor。Snapdragon 888 is made using the new Samsung 5nm process，It is the most advanced process today as well as TSMC 5nm，Qualcomm once emphasized，From technology、cost、Three aspects of functionality，Samsung technology can meet its requirements。
There are still eight cores in terms of CPU，But upgraded the new architecture，Especially the world premiere of ARM's first super large core architecture Cortex-X1，It is claimed that the theoretical efficiency is 20% higher than that of A78，Machine learning is 100% more efficient。
In Snapdragon 888，The main frequency of the X1 core is the traditional 2.84GHz，With 1MB L2 cache。There are also three A78 architecture performance-level cores，The main frequency is 2.40GHz，Each has 512KB L2 cache，And the energy efficiency core of four A55 architectures，The main frequency is 1.80GHz，Each has 128KB L2 cache。These cores have a total of 4MB Level 3 cache、3MB system cache，The total cache capacity of the entire chip reaches 8MB。
Snapdragon 888 integrates the latest generation of Adreno 660 GPU，Graphic rendering performance increased by 35%，Energy efficiency improvement by 20%。In terms of AI computing capabilities，Qualcomm Snapdragon 865 is 15 trillion times，Snapdragon 888 has reached 26 trillion times，Almost doubled in performance。
on the network，Snapdragon 888 integrated Snapdragon X60 baseband，Support millimeter wave and 5G Sub-6GHz carrier aggregation and 5G+5G dual-stop；Wi-Fi can be supported in other connections 6、Wi-Fi 6e、4K qam、Bluetooth 5.2, etc.。
In Antutu running score，Xiaomi 11 achieved more than 700,000 points，Successfully achieved the top spot。However, considering that some models using Qualcomm Snapdragon 865 and 865 Plus platforms have reached about 660,000，Xiaomi 11 should not fully realize the performance potential of Qualcomm Snapdragon 888。
In terms of storage performance，Xiaomi 11 adopts a new "full blood version" LPDDR5 memory，The main frequency is increased to 3200MHz，We tested it using AndroBench，You can see that Xiaomi 11's data is still very good，Continuous reading and writing speeds reached 1836MB/s and 756MB/s respectively，Random read and write speeds are 271 MB/s and 309 MB/s。This result has a qualitative improvement compared to Xiaomi 10 equipped with UFS3.0，Compared with the Xiaomi 10 Supreme Edition equipped with UFS3.1, it is also higher。This is the current highest-speed mobile phone memory specification，LPDDR5 flash combination with higher main frequency UFS 3.1 high-speed flash，It is indeed a perfect match for the Snapdragon 888 platform。
Game performance，In addition to several actual game tests (all based on 2K resolution)，I also used Xiaomi 11 to run 3DMark's recently launched cross-platform project Wild Life。The result is as follows，The only high score for Android now。
Game test part，First of all, the more topical version of "League of Legends" mobile game recently。With all special effects enabled，Xiaomi 11 has a score of 60.2 frames per second。
Next is "Peace Elite"，The frame rate data captured by PerfDog can be seen，It can maintain 60 frames under high image quality，Very stable。
High frame rate gaming，This time I still chose "Ace Warrior"，However, because its frame rate will drop directly to about 60fps per second due to the character's death, it will drop directly to about 60fps per second due to the death of the character.，So it still intercepted the situation in a state of survival。
During this period, the average number of frames of Xiaomi 11 was 118 frames per second.，The other segments are about 115 to 119，So it can basically be regarded as running full frame。
After running "Ace Warrior" for one hour，The maximum temperature on the front of Xiaomi 11 is 37.3℃，The maximum back temperature is 36.4℃。Although the maximum temperature is located at the lower left corner of the screen，However, because the temperature distribution in 2/3 of the entire body is relatively uniform，It can be seen that Xiaomi's cooling system has played a significant role。
But it is important to note that，The temperature at the top of the fuselage has reached 39℃，Moreover, the part where the hand contacts it will be more sensitive to temperature。If you want to play for a long time，It is recommended to wear the protective case。
Considering the above test using 2K resolution，I think the above results are satisfactory。So I also hope that in the future, "Peace Elite" can turn on the 120fps switch better，And after the high-frame rate games become rich，How does Xiaomi 11 perform?。
Next is Xiaomi 11 charging、battery life、Photographing and system performance。Xiaomi 11 has built-in 4600 mAh battery with ultra-large capacity，Supports 55W wired fast charging，45Can charge to 100% in minutes。Supports 50W wireless fast charging，Just 53 minutes to fill，Whether it's wired or wireless，The charging speed is very fast。When your other devices are out of power，When wireless charging is required，Xiaomi 11 also supports 10W reverse wireless charging，It is a very practical function。
It is worth mentioning that，In order to respond to the call for technological and environmental protection this time, Xiaomi 11，Two versions of the standard version and the set version are launched，The standard version does not include charger and data cable in the packaging，The set version includes a charger and a data cable。If the user needs a charger，Then you can choose a set version with a charger when purchasing。If no charger is needed，You can choose the standard version。
Whether it is the standard version or the set version，The price is the same，Xiaomi 11 has a 55W GaN charger，Valued at 99 yuan。Xiaomi does not cancel the charger with one size fits all，Instead, give the option to the user，Let users choose according to their needs。
It is battery life that enables 5G and Wi-Fi networks，And the brightness of the screen is 50%，Xiaomi 11 in three games and watching videos、The power consumption when browsing information is as follows。
After five hours of continuous testing，Xiaomi 11's power has increased from 99% to 22%。Among them, "Ace Warrior" can achieve 120 frames per second，This will consume more power。At the same time, the screen refresh rate is higher when browsing Weibo than watching videos，So it consumes more power。Including the pressure of 2K@120Hz screen and 5G network，Xiaomi 11 has a good battery life。But if you are a heavy user，Or if the battery life is high，Why not turn on the smart resolution power saving mode。
Of course, you can also choose to recharge your blood，Xiaomi 11 supports 55W wired second charging and 50W wireless second charging。tested，Paired with a 55W GaN charger，Can be fully filled in 47 minutes，42% can be recharged in 10 minutes，85% can be recharged in half an hour。
wireless charging，With Xiaomi 55W wireless charger，1545% can be charged in minutes，3073% can be charged in minutes，52full in minutes。But if the power is gone, it will shut down，It is recommended to re-replace it after booting，Otherwise, the fast charging agreement may not be triggered。It is necessary to note that Xiaomi 55W wireless charger needs to be used with a charger above 65W that supports Xiaomi's fast flash charging.，Therefore, the 55W charger paired with Xiaomi 11 cannot achieve full-speed charging。
Comprehensive above，I don't think I'll use my phone completely until it's out of power before charging，And it doesn't need to be fully filled，Therefore, the charging time should be controlled within about half an hour。
Image aspect，Xiaomi 11 adopts a more mainstream matrix rear camera module this year。Samsung HMX with 100 million points、1300Thousand-point ultra-wide-angle camera and telephoto macro lens。
This 100 million-point main camera has 1/1.33-inch ultra-large photosensitive components，Have a 7P lens，Support OIS optical image stabilization，Ultra HD pictures that can directly output 100 million points。When using Xiaomi 11 to take 100 million points photos，Imaging speed increased by 30%。When shooting at night，You can use the four-in-one point technology，Synthesize 1.6μm large points for taking photos，Improve the effect of taking photos at night。
1300The ultra-wide-angle lens with tens of thousands of points can provide a large field of view of 123°，And supports AI ultra-wide-angle distortion correction，Improve distortion at the edge of the picture，Take a group photo、The scenery will be better。500Ten thousand-point telephoto lens equivalent 50mm focal length，Supports 3-175px autofocus，You can get further away when shooting macros，A better experience。
also，Xiaomi 11 is also equipped with an AI master image quality engine。With the help of calculation，This top-level audio and video experience has been improved leapfrog。HDR video quality enhancement，It can also allow ordinary videos to have the same color as HDR videos；Powerful video dynamic compensation，Get rid of the limits of original frames，Make the movement of objects in the video smoother and clearer。
After turning on night view mode，Xiaomi 11 can be exposed for a long time，Effectively improve the brightness of the picture，There is much less noise。But now there will be a problem with the white sky，The background looks a little too bright。Overall，Xiaomi 11's current photography performance is average，However, the official said that it will be optimized in subsequent system updates。But it's certainly，Xiaomi 11's camera application is very useful。
For example, when shooting videos，In addition to the shortcut options at the top，You can also open the menu as shown in the left picture，Among them the resolution、Frame rate and various modes are clear at a glance。This time Xiaomi 11 also supports 8K video recording，However, it is still limited to 30 frames per second。
Xiaomi 11 also provides preset templates for VLOG creators，Simple selection and recording can generate short videos with good results。Preset duration is very suitable as the opening credits、TikTok and Moments、Weibo material。
The camera's "More" page provides two designs，The former has larger images，More suitable for placing common functions，Can be easily transferred when there is a need。Another more comprehensive，And both support custom arrangements。
In addition to hardware upgrades，Xiaomi 11 has also added a lot of creative video gameplay in terms of camera software，It can make the videos you shoot more interesting。Meet the needs of users for night shooting，Xiaomi 11 also applies the super night scene calculation of taking photos in video shooting，This way, shooting videos at night will give the picture higher brightness and purity，Significantly reduce the noise on the screen。
also，Xiaomi 11 has added Master Movie Camera Filter，The videos you shoot can have movie-like effects，You can take pictures of the master's color tuning style at will。With the function of movie lens，Able to shoot with one click, including sliding zoom、Complex video effects such as time static，Make every video you share on social networking sites more exciting。
Xiaomi 11 has also upgraded its previously well-received magic sky-changing function，More weather effects have been added，At the same time, it can also randomly generate cloud elements in the sky，Make every magic change unique。
Back to the system experience，The MIUI equipped with Xiaomi 11 itself is a representative of domestic customized OS。Whether it is localized functions、Small screen application、Both game assistance and overall optimization are very good，This time, Xiaomi 11 has made some improvements in fingerprint recognition.。
first，Xiaomi 11 still uses ultra-thin under-screen optical fingerprint module，More space can be reserved for the battery，At the same time, the brightness is lower，Not dazzling at night。And if the shortcut icon appears after unlocking。
Xiaomi 11 continues to unlock optical screen fingerprints，Added heart rate detection function，The current heart rate can be detected in just 15 seconds。
Open Xiaomi Health，Gently press your finger on the fingerprint module，The current heart rate can be recognized in just 15 seconds，According to the test results of SGS，The average error of Xiaomi 11 heart rate detection function is 2.11bpm，A little better than some wearable devices。
certainly，The implementation principle is not complicated：Blood absorbs light，So every time your heart beats，Increased blood flowing to your fingers，More light absorbed；And in the gap between heartbeat，Absorb less light。High-bright light source through the under-screen fingerprint area，You can obtain the frequency of changes in the blood of your fingers。Convert this frequency to a pulse signal，This will calculate the accurate heart rate。
have to be aware of is，During use, you need to completely cover the fingerprint area with your fingers，And just press，Excessive pressure will reduce blood flow in your fingers，Causes inaccurate results。
