Lenovo Yoga Slim 7i Carbon 13ITL5 laptop review: Tiger Lake combined with ultralight materials

White featherweight. Take a ThinkPad X1 Nano, remove some features, and paint it white. Lenovo didn't do that, obviously, but the result would probably look very similar to the Lenovo Yoga Slim 7i Carbon. Lenovo's cheaper ultralight laptop can convince in our test - but with some weaknesses.
Benjamin Herzig, 👁 Andreas Osthoff (translated by Stephanie Chamberlain), 🇩🇪 🇮🇹 ...

For some time now, the Lenovo Yoga brand has no longer only represented Lenovo's convertible series but also high-end laptops in the consumer sector in general. Until now, Lenovo's lineup in this field was often rather conventional - compact aluminum laptops with good displays such as the Lenovo Yoga Slim 7i 14, for example.

With the new Lenovo Yoga Slim 7i Carbon 13ITL5, Lenovo takes a slightly different path. It ventures into the ultralight segment with this compact 13.3-inch model that uses particularly light materials like carbon and magnesium. Mobility is clearly in the foreground here - in this respect, Lenovo likely also wants to attack the Dell XPS 13 9310, which is probably the best-known representative of the compact 13-inch class. Another interesting comparison device is the Lenovo ThinkPad X1 Nano, an in-house business counterpart that also focuses on reducing weight as much as possible. The picture is similar with the HP Elite Dragonfly.

Our test device includes an Intel Tiger Lake i7 processor, 16 GB of RAM, a 512 GB SSD, and a WQXGA LCD. This configuration costs around 1,100 Euros (~$1,289).

Case: The Lenovo Yoga meets carbon fiber

Lenovo Yoga Slim 7i Carbon 13ITL5
Lenovo Yoga Slim 7i Carbon 13ITL5

White laptops aren't common; black, silver, and gray tones tend to dominate. The Lenovo Yoga Slim 7i Carbon is among the white specimens. Except for the black B-Cover (display bezel), it is completely white. This even applies to the keyboard. Other visual elements are the glossy silver Yoga and Lenovo logos on the A-Cover (display lid). There's also a Lenovo logo on the C-Cover (palm rest).

As already mentioned in the introduction, the Lenovo Yoga Slim Carbon 7 uses a different material mix than most Lenovo Yoga laptops. Carbon fiber in the A-Cover and magnesium/aluminum in the C-Cover and D-Cover (underside); but these aren't recognizable as such on the outside. In the end, the surfaces are covered with a white layer of paint. Lenovo also uses similar materials in the ThinkPad X1 Nano. The Yoga Slim Carbon even feels almost like a ThinkPad in terms of haptics - the matte surface is pleasantly soft and isn't metallic.

Workmanship is absolutely clean. The Lenovo laptop is also stable: The C-cover can't be pressed in, and it also provides the keyboard with the necessary stability. The bottom and the display lid are a bit more flexible, but even with the very thin carbon A-cover, you have to use a lot of force to see a pressure spot on the display. The display is held securely and with little wobbling by the hinges. You can open it with one finger, and the maximum aperture angle is 180 degrees.

The weight of 975 grams is only slightly higher than that of the Lenovo ThinkPad X1 Nano. Compared with the HP Elite Dragonfly, the Yoga laptop is lighter (but the Dragonfly is also a convertible), and the comparison with the Dell XPS 13 9310 is even more clearly in favor of the Lenovo Yoga Slim 7i Carbon. The differences in case thickness are minor, and the same applies to the remaining dimensions. However, the Dell XPS 13 9310 in particular is slightly ahead in this area.

Connectivity: The Lenovo laptop focuses completely on USB

You will probably have to get used to adapters when working with the Lenovo Yoga Slim 7i Carbon, since it exclusively relies on USB-C ports (besides the 3.5 mm audio jack). All three USB-C ports can be used for charging, so that the user can choose whether to charge on the right or left side. Thunderbolt, in this case version 4, is supported by the two ports on the left. The port on the right can also handle DisplayPort in addition to USB-C Power Delivery. In total, there are three video outputs. However, Lenovo doesn't include a microSD card reader, which Dell, for example, has integrated into the XPS 13 9310.

Communication

The only communication module is the Intel Wireless AX201 chip, a modern 2x2 Wi-Fi 6 solution that does its job excellently in the Lenovo Yoga Carbon 7 Slim. With this WLAN module, the Lenovo laptop also supports Bluetooth 5.1.

There is no optional WWAN, despite the fact that this could be quite attractive for such a light and compact laptop. This is a concrete difference to the Lenovo ThinkPad X1 Nano that offers this option.

Accessories

The Lenovo Yoga Slim 7i Carbon comes with a compact 65-watt power adapter with a USB-C plug. Apart from that, there are no other accessories.

Maintenance

To access the innards of the Lenovo Yoga laptop, you have to loosen and remove six TX5 screws. For such a compact laptop, the Lenovo Yoga Carbon is still surprisingly modular: Neither the SSD nor the Wi-Fi module are soldered, and the SSD is even in the longer M.2-2280 format. On the other hand, RAM is soldered onto the motherboard. An interesting fact: The Lenovo Yoga Slim 7 Carbon has room for a second fan. However, Lenovo omits this for reasons that are unknown to us. Instead of a fan, there's a sort of dummy.

Warranty

The Lenovo PC comes with a 24-month warranty by default. Included in the package is a bring-in or pickup-and-return service. The laptop is picked up when service is needed; onsite service is not offered as an option. The warranty can be doubled to a maximum of 48 months. Lenovo also offers accidental damage protection.

Input devices: The keyboard of the Lenovo PC has a short travel

Keyboard

The white keyboard of the Lenovo Yoga Slim 7i Carbon doesn't have quite the full standard width, which is often the case in compact laptops, though. Most keys are normal size, but the Enter key, for example, is smaller. Overall, the layout corresponds to that of other recent consumer laptops from Lenovo, which also includes the small vertical arrow keys.

In terms of typing experience, the Lenovo Yoga Slim 7i Carbon struggles with the short key travel of the minimally convex keys. The pressure point is crisp. If you're used to keyboards with a longer travel, you'll make a lot of typos at first. Luckily, the keyboard frame doesn't flex. All in all, the Lenovo laptop's keyboard is easy to work with after getting used to it, but there are naturally much better keyboards.

Touchpad

The touch surface of the trackpad below the keyboard measures 10.5 x 7 cm. It's made of frosted glass, which has a high-quality feel and is ideal for gliding. In terms of hardware, it's a ClickPad that can be pressed in at the bottom to simulate the click function of dedicated buttons. The mechanism has a short travel and a clearly defined click. In addition, the touchpad is absolutely firm and does not wobble, which can happen with some cheap ClickPads. The software implementation matches the excellent design of the touchpad, which also recognizes multitouch gestures cleanly.

The WQXGA display in the Lenovo Yoga Slim 7i Carbon could be brighter

Lenovo uses a 13.3-inch LCD IPS display in the 16:10 format. The resolution is 2560x1600 (WQXGA), and the panel's surface is matte. Lenovo specifies a brightness of 300 cd/m², and there are two variants with exactly the same key specs - a low-power panel and a normal one. The normal display is installed in our test device.

The comparison clearly shows that Lenovo has cut corners in this area: The measured average brightness is 297 cd/m², which is clearly less than in the comparison laptops. The leader in this respect is the Dell XPS 13 9310, and the Lenovo ThinkPad X1 Nano also has a much brighter monitor.

Image quality seems good out of the box, but measurements with CalMan and the X-Rite i1 Pro 2 colorimeter reveal some deviations from the target. After calibration, the display can be considered to be of high quality, even though the contrast of 1,250:1 is only "good" and not "very good". This has more to do with the rather low brightness and less with the black level.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
20.8 ms ... rise ↗ and fall ↘ combined↗ 10.8 ms rise
↘ 10 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 29 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (24 ms).
       Response Time 50% Grey to 80% Grey
38.4 ms ... rise ↗ and fall ↘ combined↗ 20.4 ms rise
↘ 18 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 636 (maximum) ms. » 42 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (38.1 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM not detected

In comparison: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 14825 (minimum: 5 - maximum: 2500000) Hz was measured.

As is typical for IPS panels, viewing-angle stability is good.

Performance: Tiger Lake with solid performance in the Yoga Carbon

Two Intel Tiger Lake CPUs are available in the Lenovo Yoga Slim 7i Carbon: The Intel Core i5-1135G7 and the i7-1165G7. These are each supported by their integrated graphics unit; a dGPU isn't offered. In terms of RAM, Lenovo offers 8 to 16 GB of LPDDR4X-4266 memory that comes soldered to the motherboard.

This means that this CPU with four cores (eight threads with Hyper-Threading) has a typical maximum consumption in the range between 12 and 28 watts. The clock rates range between 2.8 and 4.7 GHz. Our CPU Benchmarks article can be used for comparisons with other processors.

40 watts, that's how much Lenovo allows the processor. However, only for a very short time. A limitation to 14 to 17 watts (15 watts on average) quickly kicks in during the Cinebench loop. Performance is roughly on par with the ThinkPad X1 Nano; the Dell XPS 13 9310 with the same chip is about 10% faster under prolonged load.

CPU throttling on battery power was not detected in this Lenovo laptop.

Storage

The Samsung PM981a is an extremely fast NVMe PCIe 3.0 SSD in the M.2-2280 format; it has a capacity of 512 GB in our review sample and hardly shows any weaknesses in the benchmarks. The 4K read rate could be better, but that's just nitpicking.

Graphics card

The Intel Iris Xe Graphics G7 (96 EU) is the strongest version of the integrated Intel graphics in the Tiger Lake chips. Compared to the G7 GPUs of the i5 CPUs, such as the i5-1135G7, this GPU has 16 execution units more. In addition, it's clocked higher in a UP3 CPU like the Intel Core i7-1165G7 installed here than in the i7-1160G7 UP4 chip found in the ThinkPad X1 Nano.

Because this is an integrated graphics chip without its own memory, the GPU has to resort to the main memory. With the very fast LPDDR4X-4266 RAM in dual-channel mode, the GPU can exploit its potential relatively fully. In the 3DMark benchmarks, the Lenovo Yoga Slim 7i Carbon achieves good results that are slightly above the comparison laptops.

A performance limitation on battery power was not observed.

Gaming performance

The GPU performance is significantly better with Intel Tiger Lake than with older Intel iGPUs. Nevertheless, the gaming capability is very limited - modern titles can only be played at heavily reduced settings.

Noise emissions

The fan is mostly off during web browsing and other tasks involving a light load. In the idle test, it only kicks in sometimes in performance mode, but it remains almost silent at 30.6 dB(a). Under load, the fan runs at 37.7 dB(a) - audible, but still not annoying.

Unfortunately, the Lenovo Yoga Slim 7i Carbon produces an annoying noise in the form of a quiet hiss. However, it's only audible when you place your ear close to the keyboard.

3DMark 11 after the stress test

With a maximum of 49.7 °C (~121 °F), the Lenovo laptop remains just below the 50 °C (~122 °F) mark. We only measured this temperature at a hotspot on the bottom. Overall, the Lenovo Yoga 7 Carbon stays much cooler. Another positive aspect is that the area around the touchpad remains completely cool.

In the stress test with combined CPU and GPU load, the processor is limited to 15 watts as in the Cinebench loop. However, this results in low clock rates of only about 1 GHz because the GPU is also running. Throttling under load can also occur in everyday use because running 3DMark 11 after the stress test results in a worse score (-23%).

Speakers

The downward-firing stereo speakers in the Lenovo Yoga Slim 7i Carbon reach a reasonable volume and even have a bit of bass - but the speakers in the Dell XPS 13 9310 and ThinkPad X1 Nano are simply a notch better.

The 3.5 mm audio output serves as an alternative, and it delivers sound flawlessly.

Energy management: The Lenovo laptop's battery life is worse than that of competitors

Energy consumption

Power consumption is higher than in the other ultralight laptops. The higher WQXGA resolution probably contributes to this, and the low-power LCD is not installed in our configuration. This is standard in the Lenovo ThinkPad X1 Nano, which clearly has the edge in terms of power consumption.

The 65-watt power adapter is of sufficient capacity for the Lenovo Yoga Slim 7 Carbon.

Battery life

Charging time: 134 minutes
Charging time: 134 minutes

Although the internal lithium-polymer battery of 50 Wh is slightly larger than the 48 Wh battery of the Lenovo X1 Nano, the battery life in our real-world Wi-Fi test at 150 cd/m² brightness is about 25% better in the X1 Nano. The higher power consumption clearly comes into play here. The difference to the Dell XPS 13, which has a slightly larger battery, is even more striking. Overall, we can conclude that the battery life of the Lenovo Yoga Slim 7i Carbon is below average.

In Lenovo's Yoga lineup, the Yoga Slim 7i Carbon 13ITL5 stands out positively with its ultralight and compact case.

Lenovo doesn't sacrifice stability and robustness for this by using carbon fiber, and it's very pleasant to work with the matte 13.3-inch display in the 16:10 format - especially since Lenovo also uses a panel with an appropriate WQXGA resolution. A very good glass touchpad is available for mouse control in the all-white Lenovo laptop. And in terms of ports, the Lenovo laptop is rather limited, but at least Lenovo thought of including a USB-C port for charging on the right as well.

On the other hand, Lenovo's omission of a card reader is a point of criticism. The same applies to the lack of a WWAN option, which we would have liked to see in this extremely portable Lenovo PC. The display brightness and battery life are also below average - Lenovo probably decided against an energy-saving, brighter low-power display for cost reasons. As for performance, it's at the expected level for Tiger Lake, and Lenovo also manages to keep the Yoga Carbon cool and relatively quiet. However, potential remains unused, since there's space for a second fan.

Compact, light, good: The Lenovo Yoga Slim 7i Carbon is an attractive small laptop for consumers looking for a mobile companion.

Overall, we have the feeling that Lenovo deliberately cut corners in some areas in order not to jeopardize sales of the more expensive Lenovo ThinkPad X1 Nano. However, this doesn't mean that the Lenovo Yoga Slim 7i Carbon is bad; on the contrary: Its much lower price compared to the ThinkPad makes it a very attractive, ultralight laptop with which Lenovo hasn't made any major mistakes.

I was an ardent reader of Notebookcheck’s laptop reviews even back in school. After writing reviews as a hobby, I then joined Notebookcheck in 2016 and have worked on device reviews and news articles ever since then. My personal interest lies more with laptops than smartphones, with business laptops being the most interesting category for me. Technology should make our lives and work easier and good laptops are an essential tool for that to happen. This is why laptop reviews are not just my work but are also my passion.

I've been fascinated with technology ever since I got my very first Android smartphone, which was quite a while ago. The power packed into such a small footprint still amazes me. Learning to program made my understanding of technology deeper, and at the same time, it expanded my interest to the area of desktop computers and laptops. All this led me to enjoy reading and watching reviews of new devices, and that's how I stumbled upon Notebookcheck. I immediately found their reviews to be very comprehensive, and luckily, I've even had the chance of translating them since 2019. When it comes to the huge field of technology, I'm currently also interested in specializing in Java programming.
