As the “first year” of 5G, in 2020, major manufacturers had originally sent good hopes for upgrades and sales to soar. However, due to the impact of the epidemic, the sales of many brands have declined, and Xiaomi has made a big splash this year, rising against the trend.
Moreover, Redmi has also made a lot of contributions. Both the Redmi K30 launched at the beginning of this year or the Redmi K30U and K30S launched at the end of the year have received unanimous praise from consumers.
It also made Xiaomi return to the third place in sales in the third quarter of this year.
At the end of the year, Redmi has brought us the Three Musketeers—Note 9 series. Let’s see if the 2020’s final product can bring us another surprise.
This time, the Redmi Note 9 series is divided into 3 models, namely the Redmi Note 9 4G, the Redmi Note 9 5G, and the Redmi Note 9 Pro.
Redmi Note 9 4G Design
Although the starting price is only three digits, the Redmi Note 9 4G still maintains a consistently high standard in terms of appearance and feel.
It has four color options, namely Dawn Orange, Haze Blue, Smoke Wave Blue, and Feather Black. So every user can find a color variant meeting his/her preferences. This time we got the fog light blue color.
The front of the Redmi Note 9 4G uses a 6.53-inch LCD waterdrop screen with eye protection. The screen resolution has reached 2340X1080 pixels, which is more delicate than other products of the same level.
It supports Xiaomi’s usual display adjustments such as sun screen, night light screen, eye protection mode, etc. This screen can provide a good look and feel, whether it is day or night, and has passed the Rhine Eye Protection certification.
The Redmi Note 9 4G uses a center-mounted water droplet full-screen design. The three-sided borders of the screen are relatively narrow. But the chin is slightly wider.
Perhaps in order to take into account the weight and durability of the body, the Redmi Note 9 4G uses a plastic backplane, supplemented by a radial texture.
The big “Redmi” logo below conforms to the current fashion trend. Although it has a large battery capacity of 6000mAh, the weight of the whole machine is still controlled below 200g.
The three-camera module is placed in the upper left corner of the back of the fuselage. It consist of a 48-megapixel Samsung GM1 main camera. The rounded edge of the module echoes the rounded corners of the fuselage.
The right side of the fuselage carries the power button and volume button. It is worth mentioning that Redmi Note 9 4G uses a side fingerprint recognition design, which combines the power button and the fingerprint recognition module into one. When the screen is lit, the phone is unlocked in one step.
The bottom of the fuselage hosts the Type-C interface, speakers and noise reduction microphone. There are no other buttons on the left side of the fuselage except the SIM card slot.
By the way, the Redmi Note 9 4G card slot is not a common “three out of two” card slot, but a standard card slot for TF+ dual SIM cards. In this regard.
The top of the fuselage retains an extremely advanced 3.5mm headphone jack, which is convenient for users to connect wired headphones.
At the same time, the Redmi Note 9 4G also supports infrared remote control function. The top speaker and bottom speaker form a dual speaker array, which has passed the HI-Res small gold standard certification.
The Redmi Note 9 4G has a clear positioning, as a “MIUI functional machine”, it guarantees the ease of use to the greatest extent and gives users the most convenient experience.
Redmi Note 9 4G Camera
Although this Samsung GM1 main camera has been used in various Redmi models for many years, long-term optimization and adjustment and polishing have given it a new life.
The 48MP ultra-definition mode brings better filming effects. The combination of 8MP ultra-wide-angle lens + 2MP depth-of-field lens makes the Redmi Note 9 4G more versatile.
Let’s take a look at the samples first.
We can see that in the case of sufficient daylight, the Redmi Note 9 4G performs stably, with more accurate color reproduction, while retaining a lot of picture details. The imaging effect is quite stable even indoors.
The image quality is slightly worse in the night environment with poor light, but it is still at a sufficient level.
After the night scene mode is turned on, the highlight suppression is better, and the overexposure condition is also improved.
Although the Redmi Note 9 4G photos did not bring much surprise, it can meet the daily record of life needs.
Redmi Note 9 4G Performance
The Redmi Note 9 4G version is equipped with the Snapdragon 662 processor, which is very close to the Snapdragon 665 specifications. Both adopt 8-core design and 11nm process. The GPU also uses Adreno 610. But DSP differs from ISP.
In AnTuTu, it scored 183,098, a slight improvement in running points compared to the Snapdragon 665.
The Redmi Note 9 also has a killer feature: the first UFS2.2 storage protocol. The WriteBooster technology is introduced on the basis of UFS2.1, which greatly improves the performance of flash memory and improves the speed of reading and writing. For models that need to control the cost of the entire machine, a significant increase in read and write speed can be achieved without a significant increase in cost.
From AnTuTu’s storage performance benchmark test, UFS2.2 has a significant performance improvement over UFS2.1.
First, we tested two popular mobile games: Honor of Kings and Peace Elite.
In Honor of Kings, all special effects are turned on and the high frame rate mode is turned on. The frame rate is stable at about 38 frames. Although it can run smoothly, the graphics card sometimes freezes.
After adjusting the special effects to mid-range, the number of frames can run stably around 60 frames.
Peace Elite has higher requirements for hardware. So the performance is affected. Peace Elite can only open smooth high frame rate or balanced medium frame rate mode at the highest picture quality, but the number of frames is quite stable.
In the actual game test, the results of the Redmi Note 9 4A are in line with the performance of this price, and can meet the daily basic entertainment needs.
The Redmi Note 9 4G has a large battery capacity of 6000mAh. With all the special effects turned on and the screen brightness is about 70%, the power consumption of Honor of Kings + Peace Elite for half an hour is only 5%.
And the screen brightness is set to half (turn off the automatic brightness), connected to WiFi to play the 1080P video, the power consumption is only 4% after half an hour. This battery life performance can fully meet the daily needs of a day.
At the same time, Redmi Note 9 4G supports 18W fast charging. But the included charger supports up to 22.5W charging.
We don’t need to worry about the ease of use of MIUI12. The GAME TURBO game accelerator box can freely adjust many parameters.
MIUI12 not only has a user-friendly update in its look and feel and user experience, but MIUI 12’s privacy protection is also more comprehensive.
The flares function makes all apps’ small actions nowhere to hide, and when the app calls the recording, positioning, and photographing permissions, it will give obvious reminders to further protect the privacy and security.
The MIUI12 on the Redmi Note 9 4G also supports the interception network function. The app can only obtain the corresponding permissions when necessary, and can be opened and closed freely.
It is directly prohibited to start recording and video recording in the background. The hidden mask can generate a virtual identity ID, allowing users to use the app with a one-time virtual identity to implement privacy protection to the end.
After experiencing the Redmi Note 9 4G, the first thing we sigh is the advancement of technology. In just a few years, it only costs a thousand yuan to get such a well-balanced smartphone with many bright spots.
The Redmi Note 9 4G not only continues Redmi’s spirit of ‘extreme cost-effectiveness’, but also implements the fun of making everyone enjoy technology.
Regardless of performance, photography, experience, appearance or workmanship, the Redmi Note 9 4G has almost no shortcomings at the same price. With a limited budget, it is a good choice to buy for parents or keep it as a spare. The Redmi Note 9 4G is a good choice.
