There are many cost-effective thin and light notebooks on the market (even some first-tier brands) that use 45% NTSC color gamut screens, which is what we often call “blind screens. Redmi Book currently on the market all use 100% sRGB or even higher color gamut screens, and the Redmi Book 16 launched today may be the best screen in the 4,000 yuan price range. Let’s first take a look at the brightness of the Redmi Book 16 screen!
1. 400nit brightness
The actual screen brightness of most 4,000 yuan thin and light notebooks is around 250nit, while the screen of Redmi Book 16 has a nominal brightness of 400nit, but its actual brightness is higher than the official data. The brightness data we measured is 420nit, even under direct sunlight outdoors. down, you can also see the screen content clearly.
2. 120Hz high refresh rate
The benefits of high-refresh screens are obvious. Previously, only mid-to-high-end thin and light notebooks would use 120Hz high-refresh screens. This time, Redmi Book 16 also uses 120Hz high-refresh screens at a price of 4,000 yuan.
Just like mobile phones, after you get used to a high refresh rate of 120Hz, it is difficult to go back to 60Hz. You always feel that the screen is flickering and swiping is not so smooth.
3. Factory color calibration
Each Redmi Book 16 undergoes screen color calibration before leaving the factory, which can control the color accuracy Delta E value to around 0.5, which far exceeds the color accuracy requirements of professional monitors.
In addition, this screen also has 100% sRGB color gamut, supports global DC dimming, and has passed TÜV Rheinland hardware low blue light certification and SGS low visual fatigue certification, making it suitable for long-term use.
In addition to the screen, Redmi Book 16 has many highlights!
It is equipped with the 13th generation Core i5-13500H processor, with 4 P-Core + 8 E-Core, a total of 12 cores and 16 threads, with a base frequency of 2.5GHz, an acceleration frequency of 4.7GHz, and the P-Core full-core frequency can reach 4.6GHz.
Redmi Book 16 has 4 performance modes, namely quiet, smart, extreme speed, and violent. The violent mode can stabilize the performance release of 47W, which is an upper-middle level among current thin and light notebooks.
In terms of expansion performance, Redmi Book 16 comes standard with Yangtze Storage PC300 512GB/1TB SSD, and also provides a PCIe 4.0 M.2 2242 interface for expanding large-capacity hard drives.
Design and Display
Redmi Book 16 is built using advanced CNC integrated carving technology, and the rotating shaft structure adopts a stronger and more durable CNC diamond rotating shaft, which can be opened and closed 30,000 times and remains stable. The thickness of the notebook is only 15.9mm and the net weight is 1.68kg.
The D surface is also formed in one piece, and the edges and corners are smoothed, making it look very rounded. There is a certification label in the middle, and there is a row of large-area heat dissipation grilles on it.
There is a Thunderbolt 4 port on the left side of the phone, which is also the charging port of the notebook. Next to it are USB 3.2 Gen1, HDMI 2.1 and a 3.5mm headset integrated port. There is a USB 3.2 Gen1 and a USB 2.0 interface on the right side of the fuselage. Strangely, they are not distinguished by color.
The 16-inch IPS screen with a ratio of 16:10 can display more content vertically and improve office efficiency. The screen has a resolution of 2560*1600, a refresh rate of 120Hz, a brightness of 400nit, and a contrast ratio of 1150:1. It also has a 100% sRGB color gamut and a color accuracy of Delta E≈0.48. It’s hard to find a better screen than this in a notebook priced at 4,000 yuan.
In addition, this screen also supports a 180-degree opening and closing angle, which is convenient for displaying the content on the screen during meetings and work. Full-size three-position backlit adjustable keyboard, 1.5mm comfortable rebound and high key travel.
In addition, in order to provide a very comfortable input experience, each keycap is designed with a hyperboloid surface and a 0.2mm concave key belly curve, which can fit the fingers very comfortably, allowing long-term typing to always remain precise and comfortable. 100W gallium nitride fast charging supports 5V3A, 9V3A, 12V3A, 15V3A, 20V5A output standards, the maximum output power can reach 100W, and it also supports 100-240V wide voltage input.
In addition to charging laptops, this charging head can also provide fast charging function for mobile phones. The charging power of 15V3A is far stronger than most current mobile phone chargers. If your phone supports 40W fast charging, you can just use this. You don’t need to spend more than 100 yuan to buy an extra fast charging head for your phone, especially when you go out, you don’t need to carry two charging heads.
After removing the heat sink, you can see the cooling system with dual fans and dual 8mm heat pipes, with a cooling efficiency of 47W.
Below is a 72Wh lithium polymer battery. Official data is that it can support 12 hours of local video battery life. There is an M.2 interface on the right side of the battery, and a Yangtze Storage PC300 1TB PCIe 4.0 SSD is plugged into it. There is also an M.2 2242 interface under the right fan for expanding the hard drive. It would be better if it was made into M.2280.

Screen and disk performance test
1. Screen test
Redmi Book 16 uses a 16-inch IPS screen with a resolution of 2560*1600 and a refresh rate of 120Hz. We used Starscream x to test the screen’s color gamut and brightness contrast.
Measured 97% of the sRGB color gamut, 72% of the Adobe RGB color gamut, 72% of the P3 color gamut and 67% of the NTSC color gamut.
The maximum brightness of this screen is 413nit, and the contrast ratio is only 670:1 at 0% brightness. At other brightnesses, the contrast ratio is above 1150:1.
In terms of color accuracy, the highest Delta E value is 4.17, the lowest is 0.17, and the average Delta E value is only 0.50.
Each screen of the Redmi Book 16 has been color calibrated before leaving the factory. Using Delta-E related technical standards as a reference, the color accuracy of this screen has exceeded the standards of professional graphics monitors.
2. Disk test
Redmi Book 16 uses the PC300 1TB SSD from Yangtze Storage, which is an entry-level PCIe 4.0 SSD product developed by Yangtze Storage specifically for the commercial market (OEM).
In the AS SSD Benchmark, this 1TB PCIe 4.0 SSD has a total score of 3206, sequential read and write of more than 3100MB/s, 2200MB/s, 4K random read of 47MB/s, and random write of 197MB/s.
In the CrystalDiskMark test, the sequential read and write speeds reached 3878MB/s and 2986MB/s respectively, and the 4K random read and write speeds were 44MB/s and 49MB/s respectively. The overall performance is very balanced and is stronger than the high-end PCIe 3.0 SSD.
3. Memory cache test
Redmi Book 16 integrates LPDDR5 6400MHz 16GB memory with timings of 60-48-48-112 CR1.
The measured memory read 67853MB/s, wrote 94820MB/s, copied 73516MB/s, and the delay was 98.3ns.
Temperature and battery life test
1. Endurance test
Redmi Book 16 has a built-in large-capacity lithium battery with a capacity of 72Wh. We used PCMark 10 to actually test the notebook’s battery life.
The scene selected for the test is a modern office in PCMark 10, the power mode is “energy saving mode”, all other processes are closed during the test, the network connection is closed, and the screen brightness is adjusted to 50%.
One thing to note here is that many thin and light notebooks have less than 100nit at 50% brightness when not plugged in, while the Redmi Book 16 has an ultra-high brightness of 210nit at 50% brightness.
The results are surprising. The Redmi Book 16’s battery life test score in the PCMark 10 modern office scenario is 11 hours and 35 minutes, which is enough to support a day’s mobile office battery life.
2. Baking machine test
We conducted a 3-hour oven test. During the entire process, the performance of the Redmi Book 16 was very stable. The i5-13500H always maintained a performance release of 47W, and the temperature was only about 82 degrees.
Many students may complain that Redmi Book 15 is only equipped with i5-13500H, while other brands of 16-inch thin and light notebooks are equipped with i7-13700H or even i9-13900H models.
It must be explained here that the Core 13th generation i7/i9 processors are extremely demanding in terms of power consumption. If you want to use their full performance, the notebook must have at least 150W of performance release, which is obviously impossible for thin and light notebooks.
Thin and light notebooks with better heat dissipation can only stabilize 45W performance output. Under this power consumption, the performance of i5-13500H is not much different from i7/i9, but the price can be hundreds or even thousands of yuan cheaper. Therefore, when pursuing cost-effectiveness, when purchasing a Core thin and light notebook, we would recommend that you choose the version equipped with the Core 13th generation i5 processor.
The following is a summary of this review:
1. The oven operates at a stable 47W for 3 hours without any frequency reduction.
This time we conducted a 3-hour baking test. The Redmi Book 16 can bake the machine as steadily as a straight line. The i5-13500H can maintain a power consumption of 47W for baking without any frequency reduction or power consumption reduction. , and the CPU temperature is only 82~85 degrees when baking.
Here we need to test again to clarify for everyone. We have indeed tested many thin and light notebooks that claim to have 60W performance release, but the price they paid is also quite tragic!
First of all, the temperature of the oven is usually above 96 degrees. Such a high temperature will greatly accelerate the aging of electronic components and is not suitable for long-term use. Another point is that the fan noise is also very loud, which greatly affects the user experience.
The heat dissipation configuration of Redmi Book 16 dual fans and dual 8mm heat pipes, the stable output power consumption of 47W is actually a very reasonable number, and there is no need to pursue the so-called 60W performance release.
2. 11 hours and 30 minutes of battery life
Media battery life tests are usually conducted at 50% brightness, so many manufacturers will play some tricks. For example, for a 300nit brightness screen, the actual brightness is even less than 100nit at 50% brightness.
The measured maximum screen brightness of Redmi Book 16 is 400nit, and it is also 220nit at 50% brightness. At this brightness, it can run 11 hours of battery life, which is more realistic than those notebooks that run 12 or 13 hours of battery life at low brightness.
The best 4K screen at the price! Redmi Book 16 review: 11 hours of battery life at 200nit brightness, three hours of baking time without clocking down
Finally, there’s the screen!
2560*1600 resolution, 120Hz refresh rate, 420nit brightness, 100% sRGB color gamut, and color accuracy of Delta E≈0.5. These parameters do not seem to be very outstanding, but a thin and light notebook with a price of 4,000 yuan can achieve these 5 at the same time. It can be said to be rare.
Redmi Book 16 is available in two storage configurations: 512GB/1TB. The initial price is 4,399 yuan and 4,699 yuan respectively. At the same price, it is difficult to find a more value-for-money thin and light book.
