Design and construction

Let’s get hands-on with the Lenovo Yoga 9i 2-in-1 Aura Edition (14ILL10). First impressions matter, and this machine certainly makes one. Living up to its “Aura Edition” name, it strikes a lovely balance – it avoids the sternness of some business laptops like the ThinkPads, yet steers clear of being overly flashy or unprofessional. Lenovo’s found a sweet spot here, crafting a device that feels undeniably premium and sophisticated, but also approachable and aesthetically pleasing. Our unit comes in what Lenovo calls “Cosmic Blue,” a deep, attractive shade. The design incorporates smoothly rounded edges and tasteful mirror-finished accents that catch the light just so, adding a touch of elegance.

Picking it up, the Yoga 9i feels reassuringly solid, constructed primarily from aluminium – CNC machined for the top cover and stamped for the bottom. There’s virtually no flex or creak, even when applying deliberate pressure. It genuinely feels robust, like a small, stylish tank, an impression backed up by its MIL-STD-810H certification covering 21 military-grade durability tests. Despite this toughness, it remains impressively svelte and relatively light, measuring just 15.9mm thick (0.63 inches) and starting at 1.32 kg (2.91 lbs). It’s definitely a portable companion. One practical point, however: while the finish is matte, it does tend to pick up fingerprints. They aren’t overwhelmingly obvious, but under certain lighting, you’ll see where you’ve handled it, so keeping a microfiber cloth nearby is advisable.

Opening the lid reveals hinges that are quite firm. You won’t be flipping this open with a single finger; the resistance is too high. But honestly, for a 2-in-1 device designed to be flipped and folded into various modes, strong, stable hinges are exactly what you want. And flip it does – this is a true Yoga, capable of rotating a full 360 degrees into tablet mode, tent mode, or anything in between, holding its position reliably.

Once open, your eyes are drawn to the display, framed by pleasingly thin bezels on three sides. The top bezel is slightly thicker, but for good reason – it houses a welcome, higher-resolution 5.0MP webcam equipped with IR for Windows Hello facial recognition. Crucially, Lenovo has included a physical privacy shutter here; it’s tiny and subtle, but provides that essential peace of mind.

Moving down to the input devices, the keyboard immediately feels comfortable. Lenovo opted not to squeeze in a NumPad, and the benefit is clear: the main keys are generously sized, making for a pleasant typing experience. It features a clean white backlight with two brightness levels, and thanks to an ambient light sensor, it can intelligently turn itself on or off based on your surroundings. Like many modern thin laptops, the Up and Down arrow keys are half-height, which always takes a little getting used to, but it’s a common compromise. Tucked neatly into the bottom-right corner of the keyboard deck, replacing a traditional key, is the fingerprint sensor, offering another quick biometric login option.

Below the keyboard sits the trackpad, and it is simply enormous, taking up nearly half the available palm rest area. Its large surface area and smooth tracking make navigation a breeze.

Ports and Connectivity

Ports and connectivity on the Lenovo Yoga 9i 2-in-1 Aura Edition (14ILL10) lean heavily towards modern standards, particularly USB-C.

On the left flank, you’ll find two highly capable USB-C ports featuring Thunderbolt 4 and USB4 40Gbps specifications. These versatile ports support Power Delivery 3.0 for charging the laptop or other devices, and crucially, DisplayPort 2.1 Alt Mode for connecting high-resolution, high-refresh-rate external displays. Accompanying them is a single USB-A port running at 10Gbps (USB 3.2 Gen 2) speeds, which also features an ‘Always On’ capability for charging peripherals even when the laptop is sleeping or off.

Moving to the right side, there’s an additional USB-C port. This one operates at USB4 20Gbps speeds (often referred to as USB4 Gen 2×2) and also supports Power Delivery 3.0 and DisplayPort Alt Mode, though limited to the still-capable DisplayPort 1.4 standard for video output. A standard 3.5mm headphone/microphone combo jack rounds out the physical ports on this side, alongside the power button. Notably absent are dedicated HDMI output and an onboard Ethernet port, meaning users requiring a wired network connection will need to utilize a USB-C dock or adapter.

Wireless connectivity is top-notch, featuring the latest Wi-Fi 7 (802.11be) standard with a 2×2 antenna configuration for potentially faster speeds and more reliable connections on compatible networks. Bluetooth 5.4 is also included for connecting wireless peripherals. This model does not come equipped with WWAN capabilities for cellular data connectivity on the go.

The maximum brightness in HDR mode is 989 cd/m² at 8% white fill and 623 cd/m² on a full white screen.

The maximum brightness in SDR mode is 480 cd/m² in the center of the screen and 481 cd/m² averaged across the surface with a maximum deviation of 1%.

The Correlated Color Temperature (CCT) on a white screen at maximum brightness is 6160K.

The contrast ratio of OLED panels is excellent because the pixels turn off completely when displaying black.

Uniformity: Luminance, Contrast, and Color Deviation

The figure below shows the results from our uniformity test across different sections of the screen. It’s measured at 185 nits (Windows slider = 67%) — a brightness level we consider typical for standard working conditions.

DeltaE values below 4.0 are acceptable for regular users. For those working with colors, screens with DeltaE values no higher than 2.0 are recommended.

Color Accuracy

Let’s check the difference between real colors and those you’ll see on the Lenovo Yoga 9i 2-in-1 Aura Edition (14ILL10). We measure that distance in DeltaE – the higher the number, the more different they look.

Values below 4.0 are acceptable for regular users, while values below 2.0 are suitable for color-sensitive work. A value below 1.0 means the difference is indistinguishable to the naked eye.

For the next graph, we’ve selected 24 common colors, including dark/light skin, blue sky, green grass, etc.

Before our calibration of the Lenovo Yoga 9i 2-in-1 Aura Edition (14ILL10), the Average color accuracy was 1.8 dE (Fig. 2), and with our Design and Gaming profile, it lowered to 1.1 dE (Fig. 3), making it almost perfect!

Comparison in the Display P3 color space.

Health Impact: PWM (Screen flickering)

Some use PWM to regulate their brightness, which means that instead of reducing the light intensity, they pulse or flicker. Our brain merges the image, so it appears darker, but this strains both it and our vision, especially when the frequency of the pulses is low. You can read more about that in our dedicated article on PWM.

In the graph below, you see the intensity of light at different brightness levels—on the vertical axis is the brightness of the emitted light, and on the horizontal axis—time.

The luminance of the Lenovo Yoga 9i 2-in-1 Aura Edition (14ILL10) display is not pulse-width modulated, providing visual comfort in the discussed aspect.

Health Impact: Blue light emissions

Installing our Health-Guard profile reduces 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.

Health Impact: Screen Reflectance

Glossy-coated displays can cause eye fatigue in high ambient light conditions due to reflections. We measure the level of screen reflection with the display turned off, at a 60° angle.

The reflectance of the Lenovo Yoga 9i’s screen is 123 GU. This is not good for outdoor use but it’s still better than most OLED models.

High Gloss: >70 GU
Medium Gloss: 30 – 70 GU
Low Gloss: <30 GU

Disassembly, Upgrade options, and Maintenance

To begin disassembling the Lenovo Yoga 9i 2-in-1 Aura Edition (14ILL10), remove the four visible screws located on the bottom panel using a Philips PH0 screwdriver.

Next, carefully lift and remove the long rubber strip situated between the hinges. This strip conceals two additional screws that also need to be removed. In total, the bottom cover is secured with six screws.

Once all screws are removed, use a plastic pry tool to detach the clips that secure the bottom panel to the chassis. Start near the hinge area and proceed gently along the edges until the panel can be lifted off.

The battery connector can then be disconnected from the motherboard using a pointed plastic tool. After that, unscrew the four screws securing the battery and remove it.

The included battery is a lithium-ion unit, model L24N4PH2, rated at 75 watt-hours with a nominal voltage of 7.7 V.

The 2242 M.2 SSD is held by a single screw. Once removed, the SSD can be pulled out from its slot. Our review unit featured a 1TB SK Hynix PCIe Gen 4 NVMe drive.

For wireless connectivity, the Yoga 9i Aura Edition is equipped with an Intel Wi-Fi 7 BE201 module. It supports 2×2 antenna configuration and operates on the 2.4 GHz, 5 GHz, and 6 GHz bands, with a maximum speed of up to 5.8 Gbps.

The cooling system includes two fans and two thin, flat heat pipes.

As for memory, the laptop uses soldered LPDDR5x RAM running at 8533 MHz in dual-channel mode. There are no available slots for memory upgrades.

Verdict

Wrapping up our time with the Lenovo Yoga 9i 2-in-1 Aura Edition (14ILL10), it’s clear this is a meticulously crafted convertible laptop aiming for the premium end of the market. From the sophisticated unboxing experience, often including genuinely useful extras like a pen and hub, to the device itself, Lenovo delivers a high-quality feel. The CNC-machined aluminum chassis feels robust, backed by MIL-STD-810H certification, yet remains impressively thin and relatively light. Its “Cosmic Blue” finish and rounded edges offer a design that’s professional without being stern, although the matte surface does tend to show fingerprints.

The user experience is largely defined by its standout features. The 14-inch 2.8K OLED display is simply gorgeous – vibrant, sharp, incredibly color-accurate (especially with calibration), PWM-free for comfort, and smooth with its 120Hz refresh rate. While its high glossiness means reflections can be an issue in bright environments, the visual quality indoors is superb. Complementing the display are comfortable input devices: a well-sized keyboard with intelligent backlighting and an enormous, responsive trackpad. The inclusion of a high-resolution 5MP webcam with a physical shutter and IR login, alongside a fingerprint reader, adds convenience and security.

Performance-wise, the Core Ultra 7 processor paired with Intel Arc graphics delivers snappy responsiveness for everyday computing, office tasks, and surprisingly decent performance for light-to-moderate gaming or creative work on the integrated GPU. The SSD is blazing fast, contributing to the overall swift feel. Connectivity is modern, relying heavily on versatile Thunderbolt 4/USB4 ports, though users needing built-in HDMI or Ethernet will require adapters or the included hub. Where the Yoga 9i truly astounds is battery life – achieving nearly 22 hours in our video playback test puts it among the absolute best, making it an exceptional choice for users prioritizing longevity away from the plug.

However, no device is perfect. The reliance on USB-C ports might inconvenience some users, and the glossy screen limits outdoor usability. The biggest consideration for future-proofing is the soldered RAM, eliminating any possibility of memory upgrades down the line. While the CPU excels in single-core tasks, it doesn’t lead the pack in demanding multi-core workloads compared to some rivals, reinforcing its position as a premium ultraportable rather than a mobile workstation. Ultimately, the Lenovo Yoga 9i 2-in-1 Aura Edition is a highly polished, feature-rich convertible that excels in display quality, build, battery life, and overall user experience. Whether it’s the ideal choice depends on prioritizing these strengths against the limitations of soldered RAM, port selection, and screen gloss.
