In 2018, Xiaomi and Redmi have many models with very similar prices, resulting in a situation of "outside must first be inside", before competing with friends, it is necessary to stand out from its own products, and the product line is chaotic and increases internal friction. At the beginning of 2019, Redmi officially became an independent brand, focusing on cost performance, and this Note 7 does interpret the word "cost performance" very specifically.
 
Redmi Note 7 has three configurations, the minimum configuration is 3GB memory 32GB storage, the price is 999 yuan, the 4 64 version is priced at 1199 yuan, and the 6 64 version is 1399 yuan. Since Redmi Note 7 is equipped with MIUI10 system, 3GB memory will often kill the background, it is not recommended, it is recommended to start with 4GB, if the replacement cycle is longer, you can consider the 6GB version.
 
The thousand-yuan machine often compromises to the cost in terms of appearance, and there will be certain trade-offs in terms of material and design, Redmi Note 7 is not too obvious, and Corning fifth-generation Gorilla Glass is used on both the front and back. Although the plastic back cover can also make the look of glass, but in terms of feel, the feel of the glass back cover is indeed better. The back is still Xiaomi's traditional vertical dual camera plus rear fingerprint unlocking, and there are no highlights at all. The middle frame is made of plastic, which doesn't have a problem, but it's a little cheap to get started. The screen protrudes more from the fuselage, and the transition to the middle frame is not smooth, and there will be a rough feel when using full-screen gestures. The top retains the 3.5mm headphone jack and IR, and the bottom connector is Type-C, which is rare at this price point, and it is well received.
 
The front is a 6.3-inch 1080P LCD waterdrop screen, the waterdrop screen will be slightly improved in terms of screen-to-body ratio compared to the notch screen, but from the perspective of appearance, the transition between this waterdrop and the edge of the screen is not smooth, slightly abrupt. LCDspecial-shaped screen will have a darkening phenomenon at the cutting position at the edge of the screen,This is not unique to Redmi Note 7,It is a common problem in the industry,The cost of raising will be improved,But it is not too demanding for a thousand-yuan machine。
 
The quality of the screen is quite good, with 99.03% coverage of the sRGB color gamut, 84.3% coverage of the P3 color gamut, 6400k in standard mode, 2.44 average Delta E, 5.82 maximum Delta E, 8000k color temperature in vivid mode, 3.5 average Delta E, and 7 in maximum Delta E. The screen has a sunlight screen function, and the maximum brightness can reach 550 nits, which is enough in strong outdoor light.
 
The processor is 2.2GHzSnapdragon 660,No frequency reduction,It's already a top Soc in a thousand-yuan machine,It's not a big problem to run mainstream mobile games smoothly,But after the overhaul, the picture has been greatly optimized,The requirements for GPU are more stringent,660It can only run at 40 frames。 If you don't usually have game needs, then let alone 660, even 636 can meet daily use.
 
The biggest controversy for the Redmi Note 7 comes from the camera. It uses a Samsung S5KGM1 sensor, although it is claimed to be 48 million pixels, but in fact, Snapdragon 660 supports up to 25 million pixels, theoretically speaking, it can also be supported by frame reduction, but S5KGM1's frame rate is 30FPS, so the hardware can't directly produce 48 million pixels, and the official claim of AI synthesis 48 million is not rigorous, four 12 million pixels can not be synthesized into one 48 million pixels. In ultra-HD mode, the photo file size will become larger, but this is not due to the increase in pixels, mainly due to interpolation, the actual imaging is improved, but it is not at the same level as the IMX586.
 
Removing the gimmick of 48 million pixels and returning to the photo performance itself, the Redmi Note 7 is excellent in its class. S5KGM1There is a 1/2 inch (1 inch = 16mm standard) outsole,This is the biggest advantage,The ability to suppress the highlights in high-contrast scenes、The ability to retain dark details is very good,Compared with the glory10Youth Edition, it has a great advantage,It also has obvious advantages over its own previously released thousand-yuan machine,But compared with IMX 363There is a significant gap。 Redmi Note 7 will launch a super night mode in the future, and its competitiveness will be further enhanced among thousand-yuan machines.
 
In terms of charging battery life, the Redmi Note 7 is equipped with a 4000mAh large battery, which is more common in thousand-yuan machines, and with Snapdragon 660, there is no need to worry about battery life. The Redmi Note 7 also supports QC 4.0 fast charging, but the 18w charging head requires an additional 10 yuan. Due to the large battery capacity, it takes 2 hours and 10 minutes to fully charge the 10W charging head, and about 20 minutes faster for the 18W fast charging head. In addition, it is worth mentioning that the Redmi Note 7 supports an 18-month warranty, which basically covers the life cycle of the mobile phone, and the after-sales guarantee is very sincere.
