Lenovo presents its Yoga Slim laptops as elegant, ultra-thin and lightweight products, allowing you to work from anywhere and give free rein to your creativity. This range of ultraportables takes its place in the manufacturer's catalog between the Yoga Pro, more powerful and a little more high-end, and the Yoga 2-in-1 with a much more specific convertible design.
In addition to versions equipped with an AMD Ryzen AI processor or an Intel Core Ultra (such as the Yoga Slim 7i Aura Edition that we also tested), Lenovo offers a version with a Qualcomm chip: the Yoga Slim 7x Gen9. Several variants are of course available, with a Snapdragon X Plus or X Elite processor depending on the case. The version of the Yoga Slim 7x that passed through the hands of 01lab is equipped with this second chip. Design, performance, and battery life: what can you expect from this Copilot+ PC, priced at 1,500 euros?
Find the Lenovo Yoga Slim 7x at the best price
An elegant design that exudes solidity
The ultraportable design of the Yoga Slim 7x, both modern and understated, catches the eye at first glance. Its smooth aluminum body gives it a solid and rigid feel, with precise assembly of the various elements, while the rounded edges contribute to a comfortable grip and emphasize the device's slimness. Compact and lightweight, the Yoga Slim 7x is only 12.9 mm thick and weighs 1.28 kg. This makes it easy to carry in a bag or briefcase, a feature that will delight mobile users, creators on the go, and students.
Upon opening the computer, the interior design is revealed, with particular attention paid to ergonomics and aesthetics. The 14.5-inch OLED display fits seamlessly, with slim bezels that maximize screen real estate while adding to the device's modern look. The webcam and infrared module are housed in a raised bezel at the top of the display, further reducing bezel thickness and making it easier to open the laptop with one hand. The plethora of stickers positioned next to the touchpad by the manufacturer, however, clashes crudely with the general elegance of the Yoga Slim 7x…
A bright OLED screen but which remains subject to glare
The Yoga Slim 7x's touchscreen has a diagonal of 14.5 inches, a size that strikes a balance between a comfortable work surface and easy portability. Its 2944 x 1840 pixel resolution and 16:10 aspect ratio provide additional vertical space compared to the traditional 16:9, particularly beneficial for productivity by facilitating the reading of long documents, web browsing, and multitasking with multiple windows open. Lenovo has clearly designed this Yoga Slim 7x for a variety of uses, ranging from daily productivity to multimedia content consumption.
Thanks to OLED technology, the screen offers absolute blacks, vivid colors – the color coverage reaches 100% of sRGB and DCI-P3 spaces – and virtually infinite contrast. The panel also benefits from a 90Hz refresh rate, offering a noticeable improvement over standard 60Hz displays and making animations and scrolling smoother and more enjoyable.
In SDR (Standard Dynamic Range) mode, the maximum measured brightness reaches 473 cd/m², ensuring good visibility even in bright environments or outdoors; this is necessary to partially compensate for the slightly high reflectance of the glossy panel measured at 114 GU despite the anti-reflective treatment, whereas a good matte screen does not exceed 50 GU. In HDR (High Dynamic Range) mode, brightness can increase to approximately 930 cd/m², allowing you to fully enjoy HDR content with an extended dynamic range. The screen is also compatible with Dolby Vision, further optimizing the viewing experience for compatible films and series.
For a device intended for creators, it is regrettable that the panel is not perfectly calibrated from the factory with an average delta E measured at 4.62; above 3, the difference between a source color and that displayed by the screen usually becomes perceptible.
Keyboard and touchpad: comfort and efficiency on the menu
The Lenovo Yoga Slim 7x's backlit keyboard adopts a chiclet layout, with Generously sized keys with small gaps between them to help reduce typing errors. The keys themselves have a 1.5 mm travel, providing noticeable tactile feedback and avoiding a shallow typing sensation. Typing is pleasant and responsive, with a satisfactory resistance when pressed. The keyboard base does not flex, even during vigorous use, ensuring appreciable stability and confirming the robustness of the whole.
The touchpad stands out for its large size, occupying a significant area under the keyboard and providing ample space for navigation and multi-touch gestures. Its smooth surface allows for smooth and precise finger gliding, while its central position under the space bar minimizes unnecessary hand movement. Modern but minimalist connectivity data-start-index="3483">The Lenovo Yoga Slim 7x's connectivity is fully based on three versatile USB 4.0 Type-C ports, offering extensive capabilities for data transfer with their 40 Gbps data rate, charging with Power Delivery 3.1 compatibility, and connecting displays with support for the DisplayPort 1.4 standard. Don't look for an audio jack, a USB Type-A port for older-generation peripherals, a memory card reader, or an HDMI output: by trying at all costs to reduce the thickness of its Yoga Slim 7x, Lenovo has inevitably had to make concessions...
No surprises, good or bad, in terms of connectivity: Lenovo's ultraportable benefits from the latest wireless connection standards with WiFi 7 and Bluetooth 5.4.
A decent audio set and webcam
Four speakers – two 2-watt tweeters and two 2-watt woofers – make up the Yoga Slim 7x's Dolby Atmos certified audio system. Facing upwards and located on either side of the keyboard, they offer sufficient sound quality for consuming multimedia content, with a satisfactory volume and good clarity for this category of ultraportable device.
Assisted by an infrared sensor mainly used for facial recognition and authentication via Windows Hello, the Yoga Slim 7x's Full HD webcam (2 Mpx) is capable of captures details accurately, but sometimes mutes colors a bit too much. It still provides decent image clarity for video calls and conferences. We will also appreciate the presence of a physical switch located on the right side of the device that allows you to electronically cut off access to the webcam, thus offering an additional guarantee in terms of confidentiality.
Scalability sacrificed on the altar of compactness
The internal design of this Yoga Slim 7x demonstrates its orientation towards compactness and efficiency, to the – logical – detriment of scalability; Lenovo has clearly sought to optimize the layout of the components here to achieve the thinnest and lightest machine possible while integrating processing power powerful enough to suit content creators.
Removing the bottom plate is easy, a good point for maintaining this ultraportable. Once removed, we discover the Qualcomm platform with a Snapdragon X Elite SoC in its X1E-78-100 version; this brings together 12 Oryon CPU cores with a maximum frequency of 3.4 GHz, an Adreno X1-85 graphics circuit with a power of 3.8 TFLOPS as well as 16 GB of LPDDR5x memory, a fixed quantity that unfortunately will not be possible to increase if necessary. Storage is entrusted to a Samsung PM9C1a SSD – replaceable, it – of 512 GB in M.2 NVMe format benefiting from a PCIe 4.0 x4 interface.
Yoga Slim 7x: our performance tests
While the Snapdragon X Elite processor in this Yoga Slim 7x appears particularly fast in multi-tasking benchmarks using only the CPU, the platform shows its limits when the Adreno graphics chipset is used, resulting in a productivity score in the PCMark 10 test that is lower than that of models equipped with a Core Ultra 200 Series. In practice, Lenovo's ultraportable still proves capable of handling office or multimedia tasks in good conditions, as long as you don't get too close to the world of 3D.
The Yoga Slim 7x is a bit slower than its competitors in terms of storage according to our measurements; in fact, the Samsung SSD is still fast enough to offer a comfortable user experience, even with several applications open.
An interesting battery life
Equipped with a 70 Wh Lithium-Polymer battery, the Yoga Slim 7x displays a battery life of 13 hours and 10 minutes according to our new test protocol. That's slightly better than competing Intel Core Ultra 200 Series platforms, but significantly behind the 17 hours of a Zenbook A14 with a less powerful Snapdragon X, admittedly. In any case, Lenovo's ultraportable allows you to work a full day away from any electrical outlet, and that's exactly what we ask of it.
Noise-nuisance, temperature and consumption
The Yoga Slim 7x's consumption is equivalent to that of competing systems based on the Core Ultra 200 series, whether at rest or under load. The Yoga Slim 7x's asymmetrical dual-fan cooling system is able to efficiently dissipate heat from the platform, keeping the palm rests cool in particular.
At the rear, the hottest point still peaks at almost 48°C at full load, a value that remains largely acceptable and will not jeopardize the lifespan of the components. It is a shame, however, that the fans are a little noisy in the same working conditions, with noise pollution measured just above 40 dB(A)…
