Red rice Redmi 9 was released on June 24 and sold for the first time on June 30. The minimum entry version is 799 yuan. Features? The price must be the same as that of MediaTek G80. There are also 1080P+LCD screens and 5020mAh batteries. Now let's take a look at the level of the G80 of MediaTek and see how the 799 bike is doing.

appearance
The packaging is even more colorful than Redmi 10X, including silicone clear water cover, 5V2A environmental friendly quick charger (18W quick charger must be purchased additionally, and Shenghui on the official website costs 29.9 yuan) and data cable.
The Redmi 9 has a factory film and does not print. Redmi 9 is available in four colors: lotus root powder (upper pink and lower blue), neon blue (upper blue and lower pink), indigo (bright green), and carbon black (gray black).
The left is visual perception, and the right is "camera perception"
The Redmi 9, which is matched with dark indigo, looks like bright green and dark green to the naked eye. If the angle and light change, it will even look like blue. Although our cameras are basically blue, the real machine is actually green
Redmi 9 does not claim that "it is not as beautiful as the portal computer", but it is really pleasing to the eye. In addition, its design idea is very special. The camera is slightly protruding, and the concentric circular road is beyond the camera. Many seniors' lessons tell us that this kind of grain is easy to hide dirt, and is not easy to take care of. The actual experience is also relatively easy to be contaminated with fingerprint oil.
Although the bottom shape is a little special, the Redmi 9 has an extremely advanced and practical 3.5mm headphone hole and infrared transmitter. One thing to say, this is really good.
The full blood card slot has a waterproof and dust-proof rubber ring. You can insert two nano SIM cards and TF expansion cards at the same time. It's really good if you don't blow it or black it. You can safely choose the version with the lowest capacity, but it's a pity that the top configuration of 1299 is available for 6G memory.
Workmanship hand feeling&fingerprint identification&volume&vibration&WiFi
Workmanship: In addition to the slightly obvious mold opening lines at the two top corners, the plastic process is very mature, and the buttons/card slots are small and tight.
feel: The radian of the back of the body is natural, and it can not be felt that this is a 5020mAh battery phone. The screen is a bit higher than the middle frame. It is a bit like the "floating screen" that was used by Early Generation OnePlus in 2014 and OPPO and Vivo in 2017. The advantage is that the grip can be very thin, but the screen is too high, and the edge is not natural to draw in.
Fingerprint: To tell the truth, I prefer the back fingerprint to the side. However, the fingerprint position is really high. Instead of worrying about accidentally contaminating the lens, we should worry about the inconvenience of touching it at ordinary times.
The feeling of vibrating motor is suitable for directly turning off. In the automotive industry, the phrase is "this car is a little loose when driving, and the vibration is not enough, and the feedback to the steering wheel is not clear enough". Undoubtedly, we have been spoiled by linear motors. The previous generation of motors are only suitable for alarm clocks and incoming calls.
The official logo is "high-power super linear speaker", the volume is standard, not as high as expected. WiFi connection speed: 2.4G WiFi is 86Mbps, 5G WiFi is 433Mbps, and it should be a 1 * 1 WiFi antenna. It meets the positioning of this price, so there is no problem.
screen
6.53 inch 2340 x 1080 resolution water drop LCD screen, official logo 400nit typical brightness, Rhine low blue light certification. Pull LOG to display the incell Tianma screen, nt36672A。 The advantage is LCD. The PPI without discount is really high and exquisite, and it can kill a large number of OLED quasi flagship.
Manual operation can reach a maximum of 380 nits, but the uniformity is OK. The four corners are all around 360 nits. There is excitation brightness, which can reach about 470 nits. But under the sun, it is not enough.
Adaptive mode sRGB color standard
But the color gamut and color accuracy are worse. No matter which mode, it can only cover about 90% of sRGB color gamut. The color accuracy of the standard mode is not even as bright and adaptive, and the color temperature around 6300K is too yellow, so this mode can be ignored directly. For daily use, it is recommended to adjust to the bright mode, and the color will be relatively good.
The visual perception is also the color of frigidity. It is white and the visual angle is small. The brightness drops obviously when the angle is slightly larger. It has a good anti peeping effect.
system
The Redmi 9 ships with MIUI 11 based on Android 10. It is expected that the stable version of MIUI 12 will be launched on July 30. Fortunately, the MIUI 12 is not delivered from the factory, otherwise the performance may be exhausted.
MIUI functions will not be repeated. China has the most complete MIUI functions, but there are many advertisements. It takes a little effort to turn off most of them. Of course, except for Yijia, Samsung HTC、 Apart from Sony and a few other manufacturers, most mobile phones have strong advertising and push.
In addition, the "minimalist desktop" suitable for the previous generation of users is, after all, the work of the Xiaomi team. It works most normally on the Xiaomi/Redmi series of machines. Users who are considering buying a smartphone can try this, which is easier to use than the simple mode.
performance
MediaTek G80, 12nm FFC process, 2* [email protected] +6* [email protected] ， GPU is Mali G52 MC2@950MHz . Dual channel LPDDR4x@1800MHz In AIDA and other software, the displayed model and P65 are MT6768. However, P65 has a higher frequency of small cores (all 8 cores are 2.0GHz, 2 * A75+6 * A55), and the GPU frequency is 820MHz.
Comparison objects: old MediaTek P60 (R15), MediaTek G90T (Redmi Note 8 Pro), Snapdragon 730G Redmi K30, old flagship Snapdragon 835 (Xiaomi 6) and classic Snapdragon 660 (Xiaomi 8 Youth Edition). If you are interested, you can go to Aiganji branch library Take your time.
CPU operation performance test
GPU graphics performance test
Storage performance test
CPU single core: Because of the advantages of the architecture, the G80 single core has overtaken the P60 and is close to the Snapdragon 835, but there is a huge gap of more than 30% between the G90T and 730G of the A76/class A76 architecture;
CPU multi-core: Fortunately, G90T and 730G have only two large cores. The gap here will be slightly smaller, about 15% - 20%. G80 basically loses 660 points to Xiaolong;
GPU ： Compared with the old P60, it is slightly improved, similar to the Snapdragon 660. However, it is far from G90T and 730G. When the pressure is low, it can reach the level of about 60% of the latter two; In the high pressure test, even less than half of them;
Flash memory: After all, it's eMMC 5.1, so we can't expect too much. Continuous and random reads are only about 60% and 75% of UFS models, and the gap between continuous writes is slightly small; While random writing benefited from the age gap of file systems, and its performance was nearly four times that of Xiaomi 6.
The core scheduling of Redmi 9 is very active, and even the screen can be full frequently. I don't know whether to say that its performance is weak, or whether to say that MIUI has greatly squeezed its performance... The daily smoothness will not be too bad, but the frame drop will definitely be.
Although the SoC performance has improved, our appetite for cancer applications has also increased, so there is no qualitative difference in the daily fluency of the entry machine every year. Of course, the hundred yuan machine in those days can't afford to push the current APP. Users with the ability to toss and turn can choose applet/web version or old version APP to improve the quality of life of these phones.

LOG file camera part
Redmi 9 camera part full set of Opfi optical module:
OV13B10 with 13 million pixels, 1/3.06 inch, 1.12 μ m
The ultra wide angle and front of 8 megapixel are S5K4H7YX, 1/4 inch, 1.12 micron
5 megapixel macro, GC5035， 1/5 inch, 1.12 micron
2 million pixel depth of field, the LOG is pulled out to show OV2180, but there is no reliable data
In fact, the depth of field of 200W can be completely omitted, so as to save labor and materials. For 500W macro, it will be more practical to change a telephoto lens. Even more simply, move the macro switch from the secondary list to the outermost (most people don't even know it exists), and the practicability of this macro head will be much better.
The imaging speed of Redmi 9 is very fast, the automatic HDR judgment is positive and average, HDR can be completed in the background (the shutter cannot be pressed for about half a second during synthesis, but it does not affect the view taking), and AI scene recognition is also accurate and fast, which is a plus for this entry-level camera.

In terms of imaging, it is a 100 yuan machine after all. Except for the wide angle range, there is not much special.
Redmi 9 There is no night view mode (ISP performance is not allowed?), The film rate of the lighting scene will decrease significantly, and it is easy to focus on the bellows. The quality of photos is to record the life level. When the light is sufficient, the white balance and discrimination are not a big problem, but the indoor or night scenes cannot be too much. Let's take a look at the sample, and we won't comment here.
Endurance&Charging&Heating
The Redmi 9 is equipped with a 5020mAh battery. After 30 minutes of "big game" (NBA 2K15), 30 minutes of wifi and 4G Internet access, 30 minutes of local video playback, and a total of 2 hours of endurance testing, the remaining power is 83%.
The large battery and entry-level SoC did not bring strong endurance, but only maintained the level of the mainstream. In addition to the backward process of 12nm, the screen RF and other parts also have to carry a part of the pot.
The Redmi 9 random charging head only has 10W head, but the machine supports 18W QC 3.0 fast charging. The measured fast charging head of Xiaomi 10 Pro has a peak power of 16W, but most of the time it maintains 15W, so the power is low. It is difficult to deal with the 5020mAh battery.
5% - 100% charging, charging from 15 minutes to 13%, 30 minutes to 29%, 45 minutes to 41%, one hour to 52%, and it takes one hour and 53 minutes to charge to 90%. It takes a total of 2 hours and 40 minutes to fully charge. The battery is too big, and it can't be much stronger with extra money. With 5V1A head, it is suitable for charging at night (specially for charging when sleeping).
In terms of heating, the room temperature is 30.2 degrees, and the humidity is 57%. It simulates the environment of a pit in summer, which is about 4 degrees higher than the normal test temperature. After 20 minutes of NBA 2K15, the highest temperature on the front of the machine appears on the right side of the top, about 44.3 degrees; The highest temperature on the back appears on the left side of the camera, which is about 44.5 degrees. Because it's a plastic fuselage, it just feels warm and performs fairly well.
summary
Unexpectedly, the performance of the entry machine in 2020 is close to that of the old mid tier god U Snapdragon 660. Unfortunately, in recent years, the demand for performance of APP has far exceeded the speed of mobile SoC toothpaste extrusion. Even though the performance is better than that of previous entry-level computers, the smoothness is just enough to maintain life.
For Redmi 9, there is no competitor in the same price range unless it is foreign garbage:
It is 100 more expensive than the Redmi 8A with the Snapdragon 439 equipped with a 6.22-inch 720 water drop screen, and the previous generation Redmi 8 (Snapdragon 439) with the same price can be delisted with honor;
If the budget goes to 999, it will step into the field of matching Redmi 10X 4G (4+128) (although the GPU of MediaTek G85 is only 50MHz higher than that of G80);
Plus 100, you can bring home the Vivo Z5x of Snapdragon 712 and 6+128, and what else can you buy;
Further up, we will meet the K30 family.
Users targeted by Redmi 9 are low budget or very light budget users. But after all, the 198g and 6.53 inch screens are not suitable for use as portable standby computers. The foothold of Redmi is also very accurate. After all, Redmi 9 supports dual card+memory card, so you can buy the most popular version of Beggar 4+64.
In the evaluation, its screen, performance, photographing, battery life, and charging are all not very good, but after all, the target positioning is higher than it. If it is put in the current hundred yuan machine, it will be commendable, and it will be better to eat with the price. If 799 yuan can be made like this, it's already a super bike.
