On December 29th, Xiaomi Mi 11 made the world’s first Qualcomm flagship processor Snapdragon 888, with top 2K screen, stronger WiFi performance, full-efficiency LPDDR5 memory, 100 million points ultra-clear main camera, 55W wired+ The fast charging combination of 50W wireless +10W reverse charging, and more importantly, the Xiaomi Mi 11 is thinner and lighter, which greatly improves the happiness index of users using mobile phones. In addition, Xiaomi Mi 11 is also Xiaomi’s first model with a plain leather version.
The size of the Xiaomi Mi 11 screen has been increased to 6.81 inches, but it is not a big circle, but it is more slender and brings a smaller body width. So Xiaomi 11 will not be more supportive than Xiaomi 10, but because the weight of the whole machine is lighter, the measured 195g including the SIM card and the screen protection film will be more handy when used with one hand.
This screen also uses a brand-new E4 luminescent material, which brings a 1500nit peak brightness, a 10-bit color depth display of more than 1 billion colors, and a resolution of 3200*1400 WQHD+, which is what we often call 2K resolution. With the front and rear ambient light sensors and Xiaomi’s self-developed screen calibration algorithm, Xiaomi Mi 11 has outstanding performance in automatic brightness adjustment and color management.
The Xiaomi Mi 11 with four-curved surface design can be described as exquisite and unusual, in which the curvature of the upper and lower sides is not obvious, which has little effect on actual use, mainly because it can reduce the visual thickness of the whole machine. The curved surface area at the border is very narrow and the curvature is small, which minimizes the distortion of the edge picture.
In addition, Xiaomi Mi 11 also supports a high refresh rate of 120Hz and a touch sampling rate of up to 480Hz, which is 4 times the refresh rate. The screen display is smoother and the touch is more precise. This improvement is very friendly to mobile game players.
It is worth mentioning that 2K resolution, high refresh rate, and DC dimming can be activated at the same time on Xiaomi Mi 11, without any reduction! In addition, the higher refresh rate and touch sampling rate can make the system’s response more timely. Even if you don’t turn on the high frame rate option, it supports four levels of refresh rate self-adjustment under the 120Hz refresh rate option.
In terms of color, every screen of Xiaomi Mi 11 has been calibrated before leaving the factory, supporting ultra-high color quasi-primary color screen and 1 billion color display, JNDC≈0.38, ΔE≈0.41. The outstanding performance of the Xiaomi Mi 11 screen has earned it a DispalyMate A+ rating.
In terms of image quality, Xiaomi Mi 11 is more than that. The newly added AI master image quality engine brings the display effect of Xiaomi Mi 11 one step closer. The AI master image quality engine can provide a variety of image and video processors, including super resolution enhancement (image and video enhancement, up to 1440P), AI smart scene optimization, video quality enhancement (HDR enhancement, more beautiful pictures, Vivid) and dynamic picture compensation (dynamic pin). Among them, the super-resolution enhancement and dynamic picture compensation cannot be turned on at the same time, because the two functions partially overlap.
It is worth mentioning that during the use process, we found that Xiaomi Mi 11 has built-in grip sensors on the top and bottom, which can cooperate with the gyroscope to determine the anti-mistouch area, and you can judge the hand control without using the point mask. In the non-grip area, turn off the anti-mistouch function and perform normal touch interaction.
The front of the Xiaomi Mi 11 uses a hidden earpiece, and the edge of the mask uses a micro-slit sound hole to ensure a full screen look and feel.
I think the picture and the audio have always been complementary, so with a better screen, the sound quality has to be improved together. Xiaomi Mi 11 uses stereo dual speakers, the sound quality has been professionally adjusted by Harman Kardon, the bottom uses 1216 super linear speaker unit, and the top earpiece two-in-one speaker constitutes the experience sound.
The sound quality and hiding effect of the top two-in-one speakers are good, but they still haven’t escaped the problem of different sound on the two sides. Xiaomi Mi 11 has also adjusted the position of the speaker, so it will not need to hold the camera to play games like Mi 10 does.
There is another reason why Xiaomi Mi 11 has attracted much attention, and that is performance. This time Xiaomi released the Qualcomm Snapdragon 888 processor for the first time in the world. Snapdragon 888 is manufactured using the brand-new Samsung 5nm process, which belongs to the most advanced process today with TSMC’s 5nm process. Qualcomm has emphasized that Samsung’s process can meet its requirements in terms of technology, cost, and functionality.
There are still eight cores in the CPU, but a new architecture layout is upgraded, especially the world’s first ARM’s first super core architecture, Cortex-X1, which claims to be 20% higher in theoretical performance than A78, and even more powerful in machine learning. 100% higher.
In the Snapdragon 888, the X1 core frequency is the traditional 2.84GHz, with 1MB secondary cache. At the same time, there are three A78-based performance-level cores, both clocked at 2.40GHz, each with 512KB secondary cache, and four A55-based energy-efficient cores, both clocked at 1.80GHz, each with 128KB secondary cache. These cores have a total of 4MB L3 cache and 3MB system cache. The total cache capacity of the entire chip reaches 8MB.
Snapdragon 888 integrates the latest generation of Adreno 660 GPU, which improves graphics rendering performance by 35% and energy efficiency by 20%. In terms of AI computing power, Qualcomm Snapdragon 865 has 15 trillion times, while Snapdragon 888 has reached 26 trillion times, almost double the performance.
In terms of network, Snapdragon 888 integrates Snapdragon X60 baseband, supports millimeter wave and 5G Sub-6GHz carrier aggregation and 5G+5G dual card dual standby; other connections can support Wi-Fi 6, Wi-Fi 6E, 4K QAM, Bluetooth 5.2 etc.
In the Antutu running points, Xiaomi Mi 11 scored more than 700,000 points and 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 Mi 11 uses a brand-new “full blood version” of LPDDR5 memory, the main frequency is increased to 3200MHz, we tested it with AndroBench, we can see that the data of Xiaomi Mi 11 is still very good, and the continuous read and write speeds are different. Reached 1836MB/s and 756MB/s, random read and write speeds were 271MB/s and 309MB/s.
This result is a qualitative improvement compared to the Mi 10 equipped with UFS3.0, and higher than the Mi 10 Extreme Edition equipped with UFS3.1.
This is the current highest-speed mobile phone memory specification. The higher frequency LPDDR5 flash memory combined with UFS 3.1 high-speed flash memory is indeed a perfect match for the Snapdragon 888 platform.
In terms of game performance, in addition to a few actual game tests (all based on 2K resolution), I also used Xiaomi Mi 11 to run 3DMark’s recently launched cross-platform project Wild Life. The result is as follows, which belongs to Android’s current unique high score.
The actual test part of the game, first of all, is the recently more topical mobile version of “League of Legends”. With all special effects turned on, Xiaomi Mi 11 ran out of 60.2 frames per second.
Next, I tested “Peace Elite” and we can see from the frame rate data captured by PerfDog that it can maintain 60 frames under high image quality, which is very stable.
In terms of high frame rate games, this time I still chose “Ace Warrior”, but because its frame rate will drop to about 60fps per second due to the death of the character, it is still intercepted for a period of survival.
During the period, the average number of frames of Xiaomi Mi 11 was 118 frames per second, and the other segments were between 115 and 119, so it can basically be regarded as running at full frame.
After running “Ace Warrior” for one hour, the highest temperature on the front of Xiaomi Mi 11 was 37.3°C and the highest temperature on the back was 36.4°C.
Although the highest temperature is located at the lower left corner of the screen, because the temperature distribution in the 2/3 area of the entire fuselage is relatively uniform, it can be seen that Xiaomi’s heat dissipation system still played a significant role.
But it should be noted that the temperature on the top of the fuselage has reached 39°C, and the part where the hand touches it will be more sensitive to temperature. If you want to play for a long time, it is recommended to wear a protective shell.
Considering that the 2K resolution is used for the test throughout the above process, I think the above results are still satisfactory. So I also hope that in the future “Peace Elite” can better turn on the 120fps switch, and after high frame rate games are enriched, how will Xiaomi mi 11 perform.
Next is the performance of Xiaomi Mi 11 in terms of charging, battery life, camera and system. Xiaomi Mi 11 has a built-in 4600 mAh super-capacity battery and supports 55W wired fast charging, which can be charged to 100% in 45 minutes. Supports 50W wireless fast charging, it only takes 53 minutes to fully charge, whether it is wired or wireless, the charging speed is very fast. When your other devices are out of power and need wireless charging, Xiaomi Mi 11 also supports 10W reverse wireless charging, which is a very practical function.
It is worth mentioning that, in response to the call for environmental protection of science and technology, Xiaomi Mi 11 has launched two versions, the standard version and the package version. The standard version does not include the charger and data cable in the package, and the package version includes the charger and data cable. If the user needs a charger, they can choose the packaged version with the charger at the time of purchase. If you don’t need a charger, you can choose the standard version.
Whether it is the standard version or the set version, the price is the same. The set version of Xiaomi Mi 11 has a 55W GaN charger, which is worth 99 yuan. Xiaomi did not cancel the charger across the board, but gave the user the right to choose, allowing users to choose according to their needs.
Battery life test. With 5G and Wi-Fi networks turned on, and the screen brightness is 50%, Xiaomi Mi 11 has a battery power of 22% after playing three games, watching videos, and browsing information content for 5 hours.
After five hours of continuous testing, the power of Xiaomi Mi 11 went from 99% to 22%. Among them, because “Ace Warrior” can achieve 120 frames per second, this power consumption will be higher. At the same time, the screen refresh rate when browsing Weibo is higher than when watching videos, so the power consumption will be more. Considering the pressure of the [email protected] screen and 5G network, the battery life of Mi 11 is still good. However, if you are a heavy user or have high battery life requirements, you may wish to turn on the smart resolution power saving mode.
Xiaomi Mi 11 supports 55W wired second charging and 50W wireless second charging. After actual measurement, with a 55W GaN charger, it can be fully charged in 47 minutes, of which 42% can be charged in 10 minutes, and 85% can be charged in half an hour.
In terms of wireless charging, with the Xiaomi 55W wireless charger, it can charge 45% in 15 minutes, 73% in 30 minutes, and full in 52 minutes. However, if it has been powered off and turned off, it is recommended to put it back again after turning it on, otherwise the fast charge agreement may not be triggered.
It should be noted that the Xiaomi 55W wireless charger needs to be used with a charger above 65W that supports Xiaomi’s ultra-fast charging, so the 55W charger with Xiaomi mi 11 cannot achieve full-speed charging.
Based on the above, I think that the phone should not be charged after it is completely used up and does not need to be fully charged, so the charging time should be controlled at about half an hour each time.
In terms of images, Xiaomi Mi 11 uses this year’s more mainstream matrix rear camera module. It includes a 100 million-point Samsung HMX, a 13 million-point ultra-wide-angle camera and a telephoto macro lens.
This 100 million-point main camera has a 1/1.33 inch large photosensitive element, a 7P lens, supports OIS optical image stabilization, and can directly output 100 million-point ultra-high-definition pictures. When using Mi 11 to take 100 million point photos, the imaging speed is increased by 30%. When shooting at night, you can use the point four-in-one technology to synthesize 1.6μm large points to take pictures to improve the night photographing effect.
The 13 million-point ultra-wide-angle lens can provide a large field of view of 123°, and supports AI ultra-wide-angle distortion correction to improve the distortion of the edge of the picture, and the effect of shooting group photos and scenery will be better. The 5 million-point telephoto lens is equivalent to a 50mm focal length and supports 3-175px autofocus. It can be farther away when shooting macro, and the experience is better.
In addition, Xiaomi Mi 11 is also equipped with an AI master image quality engine. With the help of calculation, the audio-visual experience on this top-level screen has been greatly improved. HDR video quality is enhanced, so that ordinary video can also have the same color as HDR video; powerful video dynamic compensation, get rid of the limitation of the original frame number, make the motion of objects in the video smoother and clearer.
Take a look at the actual shooting effect.
After turning on the night scene mode, Xiaomi Mi 11 can effectively improve the brightness of the picture through long exposure, and the noise is much less. But now there will be a problem of white sky, the background is too bright. Overall, Xiaomi Mi 11’s current camera performance is average, but the official said that it will be optimized in the future system update. But what is certain is that the camera application of Mi 11 is very easy to use.
For example, when shooting a video, in addition to the shortcut options at the top, you can also open the menu as shown on the left, where the resolution, frame rate and various modes are clear at a glance. This time Xiaomi 11 also supports 8K video recording, but it is still limited to 30 frames per second.
Xiaomi Mi 11 also provides preset templates for VLOG creators, and short videos with good effects can be generated by simple selection and recording. The preset duration is very suitable as a film title, Douyin, Moments, Weibo material.
The “More” page of the camera provides two designs. The former has a larger image and is more suitable for placing frequently used functions, which can be easily called up when needed. The other is more comprehensive, and both support custom arrangements.
In addition to hardware upgrades,Xiaomi Mi 11 also adds a lot of creative video gameplay to the camera software, which can make the videos you shoot more interesting.
In response to the user’s needs for night shooting, Xiaomi Mi 11 also applies the super night view of the camera to the video shooting, so that shooting video at night will make the picture have higher brightness and purity, and greatly reduce the noise of the picture.
In addition, Xiaomi Mi 11 has added a master movie camera filter, which allows you to take a movie with a movie-like effect, and you can shoot the master’s grading style at hand. With the movie lens function, you can shoot complex video effects including sliding zoom, time stilling, etc. with one click, making every video you share on social networking sites more exciting.
Xiaomi Mi 11 has also upgraded the previously acclaimed magic sky change function, adding more weather effects, and can also randomly generate cloud elements in the sky, making every magic sky change unique.
Back to the system experience, the MIUI on Xiaomi Mi 11 itself is a representative of the domestic customized OS. Whether it is localized functions, small screen applications, game assistance, or overall optimization, all are in place. This time, Xiaomi Mi 11 has made some improvements in fingerprint recognition.
First of all, Xiaomi Mi 11 still uses an ultra-thin optical fingerprint module under the screen, which can reserve more space for the battery, while the brightness is lower, and it is not glaring at night. And after unlocking, if you continue to press and hold it, a shortcut icon appears.
On the basis of the optical screen fingerprint unlocking solution, Xiaomi Mi 11 has added a heart rate detection function, which can detect the current heart rate in only 15 seconds.
Turn on Xiaomi Health and gently press your finger on the fingerprint module. The current heart rate can be recognized in only 15 seconds. According to the test results of SGS, the average error of the Xiaomi mi 11 heart rate detection function is 2.11bpm, which is slightly better than some wearable devices.
Of course, its implementation principle is not complicated: blood can absorb light, so every time a heartbeat, the blood flowing to the finger increases, and the absorbed light increases; and in the gap between the heartbeats, the absorbed light is less, passing through the fingerprint area under the screen The high-brightness light source can obtain the changing frequency of finger blood, convert this frequency into pulse signal, and calculate accurate heart rate.
It should be noted that in the process of use, you need to make your finger completely cover the fingerprint area, and you can press it lightly. Too much pressure will reduce the blood flow in the finger, resulting in inaccurate results.
