On May 10, Xiaomi released Xiaomi Max, the largest mobile phone in the Xiaomi family, with a starting price of 6.44 inch giant screen+Snapdragon 650/652+485mAh battery+1499, making its positioning very delicate.
The focus of this evaluation is the influence of machine shape, the system difference brought by the giant screen, the performance control and endurance of Snapdragon 652. Without much nonsense, we will start the film now.
Xiaomi Max is divided into three versions: Snapdragon 650+3G memory+32G storage version 1499 yuan, Snapdragon 652+3G memory+64G storage version 1699 yuan, Snapdragon 652+4G memory+128G storage version 1999 yuan. This time, we got the intermediate version.
Appearance and workmanship
Detailed pictures of articles before the welcome stamp "True · Big Screen Xiaomi Max Xiaomi 5-Hongmi Note3 Mixed Picture Appreciation" 。
There is only one slogan on the package of Xiaomi Max, and the accessories include instructions, pins, data cables and charging heads. The output of charging head is only 5V2A is a bit thick in front of the large 4850mAh battery.
The front of the fuselage is a regular rounded rectangle, and the sensor on the forehead is symmetrical with the front camera. The edge of the screen is a specially designed black edge, which is Xiaomi's landmark design language this year
The three diamond keys of Android have backlight. The front panel of Xiaomi Max uses 2.5D glass. The glass is higher than the surrounding plastic washer, and the washer is higher than the metal body. The edge sliding feels good, but the horizontal risk will be higher when falling.
The back is a three section design of "plastic aluminum plastic". The combination of plastic and metal is of average workmanship, with a slight height difference. It is worth noting that the fuselage is too large, and the index finger cannot reach the fingerprint recognition module in the normal holding posture.
Machine is All Netcom 4G+, The card slot supports nano+mirco SIM card (medium card+small card), or mirco SIM card (medium card)+TF card. The card holder cover plate is relatively loose. When our testing machine shakes, we can hear the sound of metal collision. The workmanship is average. However, the volume key and power key are of good workmanship, compact and less empty. The press feedback is crisp and slightly hard.
On the top of the fuselage is a noise reduction microphone, an infrared remote control and a headphone interface. On the left side of the bottom is a microphone, and on the right side is a speaker.

The forehead and chin of the three machines are almost the same length. The black border of Xiaomi Max is very obvious, but the actual border thickness is only slightly wider than that of Hongmi Note3. In terms of thickness, Xiaomi Max is the thinnest (7.5mm thickness).

Workmanship&feel&fingerprint identification
Weight and feel: The weight of Xiaomi Max is 203g, which is not different from the 192g of iPhone 6s Plus. The weight is acceptable. The 2.5D glass has a good touch and feel. The grain size of the back cover frosting is appropriate, so you won't feel uneasy when holding it.
Holding: The 6.44 "16:9 screen is still very wide horizontally. Even male users can hold their hands, not to mention female users. In addition, the problem of false touch caused by one handed operation of the machine has become very serious, especially when playing mobile phones in bed
Carry: The machine is longer than the back pocket of most jeans, and a small section will be exposed when it is placed in the back pocket, but as long as the pants are not too tight, the foreign body feeling will not be too heavy. However, it is unlikely to put it in the front pants pocket. When walking, you will knock yourself. When going up and down stairs or sitting down, you will risk bending your phone. It should be carried in a bag or directly in the hand.
Fingerprint identification: Like Hongmi Note3 and Hongmi 3 high configuration versions, it is post fingerprint recognition with medium speed. There is no need to light up the screen. It will vibrate when touched, and then light up the screen and unlock it. However, the fingerprint identification module is at a high position, and it can only be touched by changing the hand posture. The machine wakes up by double clicking. No matter whether the fingerprint is turned on or not, the screen does not need the power button to light up. The convenience is worth praising.
screen
Brightness extremes and uniformity: Our tester has the highest brightness of 480 nits in the center and below, and the lowest brightness of 463 nits on the top, Fairly good performance. The minimum brightness can be pressed to 1 nit, which will not be dazzling even when the light is turned off at night;
Screen quality: The Xiaomi Max uses a 6.44 inch 1080P IPS screen instead of the A-screen P-row, so there is no problem with the fineness. The color temperature in the standard mode is 8300K, and the color is cooler under the commonly used 100 nit brightness. At the highest brightness, the contrast is 1027:1, the color temperature is 9500K, and the cooling is more obvious.
Color accuracy: the best color accuracy is tested in the standard mode. The average deltaE of 104 colors is 4.6, and the maximum is 11.3. The performance is not very good. For comparison, Note 5 is 1.8, S6 edge+is 2.6, S7 edge is 2.9, Xiaomi 4S is 4.5, and Xiaomi 5 is 4.1.
Visual perception: the screen has a slightly reddish primary color, which is more pleasing to the eye than the yellow or green primary color. The overall color temperature uniformity is normal, and there is no Yin Yang screen due to the screen size. The visual angle is average. The upper left corner and the lower right corner will be white. Other directions From a large angle, the brightness attenuation is obvious, which is obvious when taking photos.
On the whole, the performance of this screen is standard, the highest and lowest brightness and uniformity are good, and the color accuracy and visual angle are weak points.
system
Xiaomi Max did not pre install MIUI 8, which was released at the same time. When we tested, the system version was MIUI 7.6.5.4 development version, based on Android 6.0.1 kernel.
The system settings are exactly the same as those of other Xiaomi mobile phones, but they are adapted to the large screen and the screen content density is higher.
When Xiaomi Max first came out, he enjoyed the function of levitation ball. Sliding on the levitation ball in different directions can trigger customized functions or apps, which is highly practical. Now the latest MIUI development version has also followed this function.
In addition, we also found that MIUI has added the function of mutual wake-up and disconnection, but it is hidden in the application sub item of "auto start control", which is very deep, and the mutual wake-up of third-party applications has been disabled by default (right figure).

Setting menu (left millet 5, right millet Max)
Theme store (Xiaomi 5 on the left, Xiaomi Max on the right)
Particularity of large screen:
MIUI does not optimize the large screen much. The machine has single hand mode, double click wake-up and levitation ball functions. Its particularity is mainly due to the larger DPI (the number of content per unit area). More content can be displayed on the same interface: there is an additional column of shortcut buttons, and half a line of content can be displayed in settings, music, calendar, home page of clock browser, yellow page, multi view, file manager, Xiaomi Finance and Tianqi. However, the content of other applications, such as app stores, photo albums, theme stores, millet wallets, millet videos, millet games, millet remote controls, is almost the same as that of the small screen of millet mobile phones.
Fortunately, third-party applications can reflect the difference of screen DPI, and have more obvious advantages in news, WeChat, microblog and other third-party applications. Some things that other machines have to slide up and down to see may be seen by Xiaomi Max in one page, which is quite pleasant to use. What is more enjoyable is the input experience. The Jiugongs keyboard is basically at the level of being able to click at random, and even the standard keyboard typing is no longer painful (laugh).
System differences:
Compared with Xiaomi 5 and Hongmi note3, which are both 3GB memory versions, Xiaomi Max will use less memory when it is powered on, leaving 1.4G after opening 8 more built-in applications, which is better than 1.2G of Xiaomi 5. The Xiaomi Max is also Android 6.0 core, perhaps due to the optimization difference of Xiaomi 5;
Xiaomi Max, Xiaomi 5 and Xiaomi 4S/4C are equipped with double click wake-up as standard, but Hongmi note3 of Hongmi series does not have double click wake-up;
However, the automatic night view enhancement function is only available in Xiaomi 5 for the time being
The MIUI advertising problem remains:
The search box will be forcibly placed in the notice bar, and advertisements will appear in the built-in file manager The search bar displayed on the desktop includes advertisements Even advertisements pop up after garbage cleaning, which is still the first in the industry
The system's own Xiaomi Finance has already set foot in the financial field, which is probably the first in the industry
Facts have proved that MIUI seems to push different advertising content for different models of devices
In the latest version of MIUI, MIUI music, video and other applications will have their own independent upgrades, which are much faster than the system itself. Some netizens even joked that this might be to block netizens' anti advertising plug-ins and advertise more timely
In addition, the boot speed and memory usage of current MIUI devices are much worse than before
The impression of MIUI in the minds of many users can almost be summarized as "ease of use, rich functions, and advertising", and we are familiar with it, so we will not introduce it here.
performance
Performance comparison between Snapdragon 652
CPU operation performance test
GPU graphics performance test
The midrange Xiaomi Max we got is equipped with Qualcomm Snapdragon 652+3G LPDDR3@933MHz +64GB eMMC flash memory. Snapdragon 650/652 is the god U widely praised by computer users this year. The CPU part of Snapdragon 652 uses 4* [email protected] +4* [email protected] The GPU is Adreno 510. Compared with the vivo X6S Plus, Xplay5 and Samsung Galaxy A9, which are also Snapdragon 652, the CPU performance of Xiaomi Max is slightly higher, and the GPU part cannot open the gap.
Comparison with cross generation flagship SoC
CPU operation performance test
GPU graphics performance test
Flash memory read/write performance test
And the previous generation of Snapdragon 808 (LG V10), Snapdragon 810 (the flagship version of Xiaomi Note) Exynos7420（Note5）， This year's Snapdragon 820 (Xiaomi 5), MediaTek MT6797T (PRO 6), Kirin 955 (Glory V8), and Snapdragon 650 (Hongmi Note3 All Netcom) are compared.
The CPU computing performance of Snapdragon 652 is even close to the 7420, the strongest of the previous generation, and it also beats Snapdragon 808/810. The 4-core 1.8GHz A72 is quite strong. However, the GPU is still a little inferior to Snapdragon 808, which is largely abandoned by the flagship SoC of these two generations. The continuous write performance of the flash memory of Xiaomi Max is even better than that of today's flagship, but the read performance can only win the honor that the read performance has always been weak and the all network communication of Hongmi Note3.
CPU copying performance/power record, temperature record, CPU and GPU baking together
Core scheduling: The Snapdragon 652 is a 28nm process, and the power consumption of 8-core fully open is not small, so the vivo X6S Plus, Xplay5 and Samsung Galaxy A9 all adopt very conservative frequency and core control. Basically, the dual core A72 is running, and the actual use experience is not far from the Snapdragon 650. However, Xiaomi Max's Snapdragon 652 is very active in regulation. A word of disagreement can open all 8 cores, and A72 can often run to the highest frequency. This full blooded 652 makes Xiaomi Max's opening and loading speed in daily applications very close to that of Xiaomi 5, the top of its own.
Stability: High power consumption means that Snapdragon 652 cannot work hard for a long time. Its thermal stability is better than that of its peers, but it is still much worse than the SoC of Snapdragon 820 and other 16nm processes. When the CPU and GPU are baked together, the four large cores can only run at 1.7G Single baking CPU:
In the first 25 seconds, 8 cores are fully open at the highest frequency, Then the frequency of the four large cores was reduced to between 1.6G-1.7G. At this time Floating point operation performance is up to 119GFLOPS, which is very close to Snapdragon 820 (120GFLOPS), and the performance is amazing;
After 40 seconds, four large nuclei hovered at 1.3-1.6G;
In about 55 seconds, two of the A72 are offline, but the other two can return to the 1.8G maximum frequency;
After 95 seconds, the dual core A72 frequency is reduced to 1.6G.
Temperature control: The price of high-performance tuning is that the power consumption is indeed higher. During the game, the machine will heat up faster. If several more applications are hung in the background, the machine will also heat up more obviously than this generation of machines. After the GPU and CPU were baked together for 5 minutes, the maximum temperature reached 95 degrees, and the temperature control mechanism was "active" to shame.
To summarize the performance, the extremely rare full blood version of Snapdragon 652 on Xiaomi Max is absolutely performance frenzy. The 4-core A72 can increase the speed when the daily application is on, but it will return to the Snapdragon 650 after continuous use. The basic summary is "It feels like a Snapdragon 820 when used slightly, but it will return to 650 when working for a long time" 。
photograph
We have taken photos of four new Xiaomi machines before. If you are interested, you can poke the link "Comparison of peers! Xiaomi Max - Xiaomi 5 - Hongmi Note 3 - Xiaomi 4S Photo Review" 。
Guess the camera model of Xiaomi Max: According to the actual wide-angle and exif information of the film, the focal length is the same as that of the red rice Note3 All Netcom, and the sensor size should also be 1/3.06 inch. For the 16 million pixel sensor of this size, the most common ones are the Samsung interpolation version of S5K3L2 and the Hongmi Note3 All Netcom version of S5K3P3. The former does not support phase focusing, so Xiaomi Max is likely to use the sensor of the Hongmi Note3 All Netcom version.
However, there is doubt that the limit state of Xiaomi Max is 3153 ISO and 1/14 second shutter, while Hongmi Note3 All Netcom is 6400 ISO (the device with the highest ISO extreme value in Xiaomi's history) and 1/10 second shutter. Possible reasons include different sensors, algorithm changes, and EXIF information errors, which cannot be confirmed temporarily.
Effect speculation: The hardware parameters of Xiaomi Max and Hongmi Note3 All Netcom are very similar, and the performance is not far different. The 1.0 micron ultra small unit pixel size of the CMOS S5K3P3, even with ISOCELL technology, is estimated to be weaker in daytime and weak light imaging than the Xiaomi 4S, and the gap between them and the IMX298+optical anti shake Xiaomi 5 is estimated to be further.
Photo experience
Intelligence: The HDR and night view modes of Hongmi Note3 and Xiaomi Max can only be opened manually, which is less intelligent;
Shutter response and imaging speed: The shutter response and imaging speed of MIUI are always fast, from Hongmi Note3 to Xiaomi 5 The sample processing speed of Xiaomi Max's HDR and night view mode is average;
Focus: The machine supports phase focusing. The focusing speed is good under daylight and normal light. Although the speed decreases under dark light, the focusing success rate is relatively high;
Film rate: No problem during the day, but there will be a greater chance to shake the film under the brightness level of the lighting scene, which is average.
HDR and night view mode effects
The availability of the HDR algorithm of MIUI camera has always been low, and there is no sign of improvement on the latest Xiaomi Max. HDR sample The effect is very unnatural. In addition to the dark details will be excessively brightened, the color saturation will be too high, and the white balance will be significantly shifted, its excessive traces will be stiff, and algorithm smearing and sharpening will be intensified. In the same sentence, let the HDR function of MIUI remain closed
In addition, the white balance of Xiaomi Max is not very stable. If the focus is slightly shifted, the white balance of the flakes will change significantly
Xiaomi Max dual mode, extremely weak light scene contrast
Xiaomi Max dual mode, light scene contrast
Xiaomi Max adopts a night scene mode algorithm similar to Xiaomi 5, which reduces noise smearing (even no smearing trace can be seen) in order to retain the discrimination. The discrimination and color saturation remain intact, but color noise with large granularity does affect the appearance.
Lens quality&wide angle
Actual sample size comparison: all samples are 4:3 samples. Hongmi Note3 All Netcom and Xiaomi Max with the same focal length have a slightly larger wide-angle/imaging field of view than Xiaomi 5 (the common 28mm equivalent focal length), and Xiaomi 4S is the smallest (30mm equivalent focal length).
The sample sheet is magnified proportionally to compare the same object
Analytic prediction: The same object has more pixels in the proof, and its discrimination will be more advantageous. Although the Xiaomi 4S has only 13 million pixels, its wide-angle range is smaller than that of other machines. To a large extent, it "sacrifices" the viewfinder range to alleviate the weakness in the number of pixels In the proof, the object is larger than 16 million pixels in wide angle Hongmi Note3 All Netcom and Xiaomi Max are larger.
The left is the sample after repeatedly wiping the lens, and the right is the sample in normal use
Lens glare: Xiaomi Max's lens quality is relatively ordinary, with obvious radioactive light, fog and flare, and purple light spots appear beside the strong light, which is far behind Xiaomi 4S and Xiaomi 5. In addition, the lens glass of Xiaomi Max is very easy to absorb oil and cause serious glare, which can be avoided by wiping the lens with lens wiping cloth for many times. Its maintenance is too difficult, and it is difficult for ordinary users to avoid the problem of "oil spill" of the lens during normal use. It is necessary to avoid the strong front light source as far as possible.
White balance&metering&saturation
PS： This part of the sample is used to compare the white balance, photometry and color saturation, and the discriminant force sample is concentrated in the last part
Sun Scene 1
Daylight scene 2 (both are biased. Relatively speaking, red rice note3 metering is more accurate, but the white balance is slightly green)
Daylight scene 3 (all different green)
Daylight scene 4 (all different red)
Light Scene 1
Light Scene 2
Weak light scene 1
Weak light scene 2
metering: Xiaomi Max will be slightly darker, and the dimming range will be more obvious under weak light.
White balance: Xiaomi's photography algorithm still needs to be improved. In the daytime with lower difficulty in white balance, once encountering a scene with slightly larger object contrast (the sky in Scene 3 and the bushes in Scene 4), the white balance and color saturation of the four Xiaomi devices (the flowers in Scene 5) are different. In general, Xiaomi Max tends to be yellow.

In daytime and lighting scene, Xiaomi Max's high pixel advantage has been flattened by the wide-angle lens, and its analytical performance is average, even the noise control in the daytime scene is average.
In the low light scene, As expected, Xiaomi 5 has left other machines by a large margin, followed by Xiaomi 4S. Hongmi Note3 is the bottom of all Netcom. Xiaomi Max is much better than Hongmi Note3. If they are really the same sensor, it is the victory of Xiaomi's new algorithm, but there will be obvious losses in the purity and first impression of the image.
Endurance&Heating&Charging
Xiaomi Max is equipped with a 4850mAh battery. After 30 minutes of large-scale games (NBA 2K15), 30 minutes of wifi and 4G Internet access, one hour of music playing and 30 minutes of local video playing, the remaining power is 82% after a full three hour endurance test.
Its performance is quite amazing. Its performance is close to that of the Hongmi 3 with a 5-inch screen+410mAh battery, leaving the Hongmi Note3 and almost all conventional models behind. Turn on 4G and wifi standby for 8 hours, and the power failure is between 1-2%. Daily heavy use can last for 2 days, and it is not a big problem to charge every 3-4 days for light use. The measured automatic brightness of the whole process, the live broadcast of wifi fighting, the machine can last for 8 hours, and the endurance performance is quite violent
The original charger 5V2A, the actual charging power is about 10.7W.
The charging head on Xiaomi 5 supports Qualcomm QC3.0 fast charging, and can go to 12.5W when the screen is off. The bright screen can reach 15.3W, but the difference is estimated to be occupied by the machine operation. The input power is estimated to be about 12W, which is far less different from the original charger.
The original charger and the fast charger are used for charging respectively. The fast charger is not fast enough for the original charger to start. The advantage of the fast charger is that the speed remains more firm. In the end, the fast charger takes 167 minutes (2 hours and 47 minutes) to fully charge from 5%, while the original charger takes 183 minutes (3 hours and 3 minutes). The speed is also not as high as expected, Maybe there is a certain charging speed limit in the body. But it is certain that, This is bad news for users who use chargers to significantly increase their charging speed.
The room temperature is about 28 degrees. After running NBA 2K15 for 30 minutes, the highest temperature on the front of the machine appears below the front camera, which is 44 degrees; The highest temperature on the back appears near the fingerprint identification module, which is about 40 degrees. Although the heating performance is better than that of the Snapdragon 810, it is really average in this generation of machines.
Summary
The "Max" of Xiaomi Max refers to the size of the screen and the body. Its price and positioning are actually lower than that of Xiaomi 4C/4S. In addition to the price, the 6.44-inch giant screen and photo performance of Xiaomi Max are just in line with its own price, The training and endurance performance of Snapdragon 652 is a surprise.
The target audience of Xiaomi Max is very clear, that is, heavy entertainment users supported by the giant screen and endurance. The portability and operation convenience are obviously ranked behind the screen size. It is doomed that Xiaomi Max is a machine that people who like giant screen can't put it down, but those who don't need giant screen feel weak. But what we can tell you is that for the former, Xiaomi Max has made a good choice; But for non heavy users, it is not recommended to try.
