Lenovo Yoga Slim 7i (13″) review – a thin and light banger
Lenovo is now offering most of its notebooks in both Intel and AMD iterations. However, they seem to be really proud of the involvement of Intel in “co-engineering” the Yoga Slim 7i (13″). Ultimately, this means that the device is part of the Evo platform. What it aims to deliver are performance, responsiveness, and stability. If we have to be honest, there is no Evo-dubbed laptop that we haven’t found impressive.
And we have a feeling that today we won’t be disappointed. The device in question has a WQXGA IPS panel with a 16:10 aspect ratio and 2560 x 1600p resolution. It supposedly covers 100% of the sRGB gamut, which would be great. Of course, we are going to check that later on.
Ultimately, the 13-inch iteration of the Yoga Slim 7i is the first 13-incher from the series. And we are really looking forward to exploring its extremely small form factor.

全部 Lenovo Yoga Slim 7i (13″) 配置
What’s in the box?
This notebook’s packaging includes a 65W USB Type-C power brick, some paper manuals, and a USB Type-C dongle.
Design and construction
As we said, the Yoga Slim 7i (13″) has an extremely portable body. It weighs 1.21 kg and has a profile of just 13.8-14.9mm. Interestingly, these are the measurements of the all-aluminum device. Lenovo also offers a “Carbon” version, which has a carbon fiber lid, and a magnesium-aluminum alloy base. The latter is a bit thicker at 14.25-15mm, but is significantly lighter – 966 grams. Since we have the aluminum device, we can only evaluate its built quality. With that said, it is incredibly good and sturdy. And realistically, it feels extremely thin.
Also, we were impressed by the fact that its lid can be opened with a single hand. If you look closely, you will see that the bezels around the glossy display are extremely thin – all around. The top one has a slight notch, which houses the HD camera, the IR face recognition sensor, and helps to grip the lid when you open it.
Unsurprisingly, the keyboard is not your typical unit, as it has to comply with the super-slim chassis. This results in short key travel but rather tactile and quiet feedback. Ultimately, the experience we got was great. Additionally, there is a glass-covered touchpad. It boasts an excellent gliding and tracking experience. As one would expect, its clicking mechanism also has short travel.
Lastly, the bottom panel has two speaker cutouts, and one ventilation grill, with the hot air escaping from two vents on the back.
Ports
In terms of I/O, you get two Thunderbolt 4 connectors to the left, as well as one USB Type-C 3.2 (Gen. 2) port, and an audio jack on the right. Thankfully, Lenovo includes a dongle inside the package, that offers HDMI, VGA, and USB Type-A outputs.
Display quality
Lenovo Yoga Slim 7i (13) is equipped with a WQXGA IPS panel, B133QAN02.0 (LEN8198). Its diagonal is 13.3-inch (33.8 cm), and the resolution – 2560 x 1440p. Additionally, the screen ratio is 16:10, the pixel density – 227 ppi, their pitch – 0.11 х 0.11 mm. The screen can be considered Retina when viewed from at least 38 cm (from this distance, the average human eye can’t see the individual pixels).
Viewing angles are comfortable. We offer images at different angles to evaluate the quality.
The maximum measured brightness is 340 nits (cd/m2) in the middle of the screen and 325 nits (cd/m2) average across the surface with a maximum deviation of 7%. The Correlated Color Temperature on a white screen and at maximum brightness is 6200K – slightly warmer than the 6500K temperature standard for sRGB.
In the illustration below you can see how the display performs from a uniformity perspective. The illustration below shows how matters are for operational brightness levels (approximately 140 nits) – in this particular case at 81% Brightness (White level = 141 cd/m2, Black level = 0.08 cd/m2).
Values of dE2000 over 4.0 should not occur, and this parameter is one of the first you should check if you intend to use the laptop for color-sensitive work (a maximum tolerance of 2.0 ). The contrast ratio is very good – 1800:1.
To make sure we are on the same page, we would like to give you a little introduction to the sRGB color gamut and the Adobe RGB. To start, there’s the CIE 1976 Uniform Chromaticity Diagram that represents the visible specter of colors by the human eye, giving you a better perception of the color gamut coverage and the color accuracy.
Inside the black triangle, you will see the standard color gamut (sRGB) that is being used by millions of people on HDTV and on the web. As for the Adobe RGB, this is used in professional cameras, monitors, etc for printing. Basically, colors inside the black triangle are used by everyone and this is the essential part of the color quality and color accuracy of a mainstream notebook.
Still, we’ve included other color spaces like the famous DCI-P3 standard used by movie studios, as well as the digital UHD Rec.2020 standard. Rec.2020, however, is still a thing of the future and it’s difficult for today’s displays to cover that well. We’ve also included the so-called Michael Pointer gamut, or Pointer’s gamut, which represents the colors that naturally occur around us every day.
The yellow dotted line shows Lenovo Yoga Slim 7i (13)’s color gamut coverage.
Its display covers 96% of the sRGB/ITU-R BT.709 (web/HDTV standard) in CIE1976, providing a punchy and vibrant image.
Our “Design and Gaming” profile delivers optimal color temperature (6500K) at 140 cd/m2 luminance and sRGB gamma mode.
We tested the accuracy of the display with 24 commonly used colors like light and dark human skin, blue sky, green grass, orange, etc. You can check out the results at factory condition and also, with the “Design and Gaming” profile.
Below you can compare the scores of Lenovo Yoga Slim 7i (13) with the default settings (left), and with the “Gaming and Web design” profile (right).
The next figure shows how well the display is able to reproduce really dark parts of an image, which is essential when watching movies or playing games in low ambient light.
The left side of the image represents the display with stock settings, while the right one is with the “Gaming and Web Design” profile activated. On the horizontal axis, you will find the grayscale, and on the vertical axis – the luminance of the display. On the two graphs below you can easily check for yourself how your display handles the darkest nuances but keep in mind that this also depends on the settings of your current display, the calibration, the viewing angle, and the surrounding light conditions.
Response time (Gaming capabilities)
We test the reaction time of the pixels with the usual “black-to-white” and “white-to-black” method from 10% to 90% and vice versa.
We recorded Fall Time + Rise Time = 27 ms
After that, we test the reaction time of the pixels with the usual “Gray-to-Gray” method from 50% White to 80% White and vice versa between 10% and 90% of the amplitude.
Health impact – PWM / Blue Light
PWM (Screen flickering)
Pulse-width modulation (PWM) is an easy way to control monitor brightness. When you lower the brightness, the light intensity of the backlight is not lowered, but instead turned off and on by the electronics with a frequency indistinguishable to the human eye. In these light impulses, the light/no-light time ratio varies, while brightness remains unchanged, which is harmful to your eyes. You can read more about that in our dedicated article on PWM
Lenovo Yoga Slim 7i (13)’s backlight doesn’t utilize PWM at any brightness level. This makes it comfortable and safe for work across long periods of time.
Blue light emissions
Installing our Health-Guard profile not only eliminates PWM but also reduces the harmful Blue Light emissions while keeping the colors of the screen perceptually accurate. If you’re not familiar with the Blue light, the TL;DR version is – emissions that negatively affect your eyes, skin, and your whole body. You can find more information about that in our dedicated article on Blue Light.

The cooling solution of this notebook is really impressive. It was working way above its base clock and maintained its high frequency throughout the entire test.
Comfort during full load
For this test we used the Extreme performance preset. This results in a pretty high noise level, and relatively warm keyboard temperature. On the other hand, you can choose an alternative preset, which will drive both temperatures, and noise down.
Verdict
Lenovo promised a hassle-less, snappy experience with great performance. We are glad to say that they have managed to achieve it. Whether it is thanks to the Evo platform of Intel or not, we don’t care. What we do care about is that you get what you are promised and that this little machine can deliver exceptional performance both on the computational, and on the graphics side.
It is such a bummer that you can’t make use of a populated I/O. Although the port selection doesn’t seem too bad with two Thunderbolt 4 connectors, and one additional USB Type-C port, this is pretty much all you get. Nevertheless, you get a dongle inside the box, which extends one of the Type-C ports to VGA, HDMI, and USB Type-A ports – not too shabby.
Lenovo Yoga Slim 7i (13)’s IPS panel (B133QAN02.0) has a WQXGA resolution, comfortable viewing angles, and a very good contrast ratio. It boasts 96% sRGB coverage, and thankfully – it doesn’t use PWM. Moreover, with the help of our Gaming and Web design profile, it manages to deliver a very high color accuracy. This means you can use it for e-commerce, and Web design work.
By the way, this laptop is offered with two 1600p displays, one of which is dubbed as a “low power” one. We are not sure if our unit was equipped with such, but we got a pretty decent battery score. It manages 12 hours and 43 minutes of Web browsing, and almost 9 hours of video playback. This results in a full day worth of battery power.
Yes, the memory of this model is soldered to the motherboard, and the options are limited to 8 and 16GB of LPDDR4x RAM in dual-channel mode. However, you have one storage expansion slot in the form of an M.2, which supports PCIe x4 drives.
At the end of the day, the great build quality, and the extremely portable body just compliment what this laptop really is – a thin and light banger.
