If you are here, you are probably in the search of an affordable everyday notebook. This means your expectations won’t be high, but you can definitely make use of some power, decent battery life, and a good display. Right?
Well, surely, you can rely on the first of the aforementioned features. Indeed, this notebook can be purchased with up to the Core i7-1165G7 and a GeForce MX450 graphics card. Of course, this will bring the price to a not-really-affordable state. Therefore, the Core i5-1135G7 with an integrated GPU can be a good middle ground.
Something you definitely should not make compromises on, however, is the display. Since this unit is sold with either IPS and TN panels, we strongly suggest going for the former, due to its superior contrast ratio and viewing angles. If this is indeed what you look for, then, you will be happy to hear that the unit we have with us has exactly these specifications.

Lenovo IdeaPad 3i (15″, 2021) - Spécifications
What’s in the box?
Inside the package, you have some paper manuals and a 65W power brick.
Design and construction
To get some insight into just how portable this laptop is, we have to take a peek at its measurements. Here, we see a weight of 1.65 kg, and a profile of 19.9mm. Indeed that makes it super comfortable to carry, even at 15-inches in diameter. Unfortunately, the build quality is not great. As the laptop is made entirely out of plastic, we see that the base is super bendy. Definitely refrain from flexing it.
Expectedly, the lid cannot be opened with a single hand. Moreover, the hinges are pretty poor, and make the screen wobble, as soon as you touch the notebook. At least on the bright side, you get slim bezels, an HD Web camera, and a privacy shutter.
When we look at the base, we see a power button, which features an optional embedded fingerprint reader. Quite a rare feature at this price point. Then, there is the keyboard. First and foremost – it has a NumberPad, and an optional backlight, which is great. Also, the keystrokes are decently long, while the feedback is clicky. However, it is a bit inconsistent, plus, we noticed a nasty deck flex.
In fact, the flex is so severe, that the entire base bends when you even click the top portion of the touchpad. Other than that, the touchpad is fine, as it has a Mylar surface, which offers a smooth gliding experience.
Now, let’s take a quick look at the bottom panel. First, you can see that it is made from easily scratchable rough plastic material. Also, there are the speaker cutouts, which hide both 1.5W speakers. In addition to that, you can find the ventilation grill. Hot air, respectively, is being blown away from a vent in between the base and the lid.
The majority of the I/O is located on the left side. There, you will find the power plug, a USB Type-A 3.2 (Gen. 1) port, an HDMI 1.4b connector, a USB Type-C 3.2 (Gen. 1) port, and an audio jack. Then, on the right, there’s a USB Type-A 2.0 port, and an SD card slot.
Disassembly, upgrade options and maintenance
To take this laptop apart, you need to undo 10 Phillips-head screws. After that, pry the bottom panel with a plastic tool, and remove it from the chassis.
The battery here is a bit underwhelming with a capacity of the only 38Wh.
First, let’s talk about the soldered memory. There is either 4GB or 8GB of RAM that is nonremovable. Additionally, you get one SODIMM slot, that works together with the soldered memory in dual-channel mode. Storage-wise, you get one M.2 PCIe x4 slot, as well as a 2.5-inch SATA drive bay.
Looking at the cooling solution, we see a rather thin heat pipe and a fan that looks quite big.
Lenovo IdeaPad 3i Gen 6 (15″) comes with a Full HD IPS panel, model number LG LP156WFH-SPP1 (LGD069A). Its diagonal is 15.6″ (39.62 cm), and the resolution – 1920 х 1080p. Additionally, the screen ratio is 16:9, the pixel density – 142 ppi, their pitch – 0.18 x 0.18 mm. The screen can be considered Retina when viewed from at least 60 cm (from this distance, the average human eye can’t see the individual pixels).
The viewing angles are good. We offer images at different angles to evaluate the quality.
The maximum measured brightness is 312 nits (cd/m2) in the middle of the screen and 288 nits (cd/m2) average across the surface with a maximum deviation of 15%. The Correlated Color Temperature on a white screen and at maximum brightness is 6200K (average) – slightly colder than the 6500K optimum 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 82% Brightness (White level = 140 cd/m2, Black level = 0.14 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 decent – 1000:1.
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 IdeaPad 3i Gen 6 (15″)’s color gamut coverage.
Its display is limited just to 51% of the sRGB/ITU-R BT.709 (web/HDTV standard) in CIE1976.
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 IdeaPad 3i Gen 6 (15″) 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 = 26 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 IdeaPad 3i Gen 6 (15″)’s backlight does not use PWM at any brightness level. This ensures comfort to the eyes in this aspect.
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.
Lenovo IdeaPad 3i Gen 6 (15″)’s IPS panel has a Full HD resolution, comfortable viewing angles, and a good contrast ratio. Thankfully, it doesn’t utilize PWM for brightness adjustment, which makes it safe. Of course, since this is a budget panel, it covers only half of the sRGB color gamut. Moreover, the color representation is not accurate, whatsoever.
Buy our profiles
Since our profiles are tailored for each individual display model, this article and its respective profile package are meant for Lenovo IdeaPad 3i Gen 6 (15″) configurations with 15.6″ LG LP156WFH-SPP1 (LGD069A) (FHD, 1920 × 1080) IPS.

We have to say that despite the budget nature of this notebook, Lenovo didn’t spare any resources and efforts in designing its cooling solution. As you can see, even under extreme workloads, the device can maintain a frequency higher than the 2.40 GHz base one for this processor.
Comfort during full load
The laptop is not too warm on the keyboard, neither it is too loud, which is good.
As we said at the beginning of the review, your expectations should have been low. Unfortunately, the IdeaPad 3i Gen 6 (15″) kind of proved this with its poor build quality. Interestingly, Lenovo has shown with a lot of ThinkPads that it can make good-quality plastic devices. However, this particular laptop falls short of that, as its chassis is super bendy, and the hinges are unstable. Given the fact that the build is what provides the first impression, we feel that they could have done a better job.
On the other hand, we were pleased with the performance it provides. Its cooling solution is capable of handling the ULV CPUs without a hassle, and the upgrade options are on point. Thankfully, its soldered memory can work in dual-channel mode, when paired with a SODIMM RAM module. Also, there is an M.2 PCIe x4 slot, and a 2.5-inch SATA slot for storage upgrades.
Lenovo IdeaPad 3i Gen 6 (15″)’s IPS panel (LG LP156WFH-SPP1 (LGD069A)) has a Full HD resolution, comfortable viewing angles, and a good contrast ratio. Thankfully, it doesn’t utilize PWM for brightness adjustment, which makes it safe. Of course, since this is a budget panel, it covers only half of the sRGB color gamut. Moreover, the color representation is not accurate, whatsoever.
We were really impressed by the battery life here. And not because it was anything spectacular. At first, we were really disappointed to see a 38Wh unit powering the laptop when it’s not plugged in. However, it lasted for 7 hours and 44 minutes of Web browsing, and 7 hours of video playback, which is quite a respectable result. This indicates great optimizations by Lenovo on the software front.
We should also not forget to mention that the I/O includes a USB Type-C port, and an SD card reader among the rest of the ports, which can be quite useful. And there are additional features, that include a privacy shutter, an optional keyboard backlight, and a fingerprint reader.
At the end of the day, we can’t really recommend this device because of the poor quality of the build. At the same time, we don’t feel that advising against a purchase is also very reasonable. So, the ball is in your court. What do you think? Do the perks outweigh the quirks?
