2025 Lenovo Yoga 9i laptops (gen 10): Yoga 9i 2-in-1, Yoga Slim 9i, Yoga Book 9i

Lenovo are updating their premium lineups of Yoga thin-and-light ultrabooks for 2025, and in this article we’re discussing their top-tier Yoga 9i 10th-generation refreshes.

These are all 14-inch Copilot+ laptops, and are available as a clamshell Yoga Slim 9i, a 2-in-1 convertible Yoga 9i 2-in-1 Aura Edition, and a revamped iteration of the dual-display convertible Yoga Book 9i.

These are all built on Intel’s Lunar Lake hardware platform, with LPPDDR5x memory and large batteries, so they’re not designed for sustained performance, but rather promise solid daily use experience and excellent runtimes on battery power. You’re also getting modern-generation OLED touch displays on all these Yoga 9is, as well as premium metal builds, comfortable inputs, and minimalist IO mostly built around UBS-C Thunderbolt 4 ports.

We’ll review these over the next few months, but for now, let’s discuss the specs sheets and briefly go over what has changed on these 2025 Yoga 9i models compared to their predecessors.

2025 Lenovo Yoga Slim 9i gen 10, Yoga 9i 2-in-1 gen 10 (vs. 2024 Yoga 9i 2-in-1 gen9)

Yoga Slim 9i

The Slim 9i is a clamshell chassis with what looks like a 180-hinge (or close to). It’s the most compact and lightweight variant of these Yogas, at 2.62 lbs and 12.3 x 8 inches in footprint. For comparison, a MacBook Air 13 is 2.7 lbs and 12 x 8.5 footprint, while offering a smaller display and battery.

The design and build quality are premium on this Slim 9i, much as I’d expect from a premium-tier Yoga, with solid metal pieces all around and shiny rounded edges.

In fact, this Slim feels quite similar to the previous Yoga Slim 9i from a few years ago and the latest Yoga 9i convertible variants. The branding and markups have been slightly retouched and cleaned up for this model year, though, and the series is available in a single color called Tidal Teal, which is a sort of marine green to my eyes.

Despite its compact size, there’s plenty of space on this chassis for a full-keyboard with 1.5 mm travel depth and a .3 mm dash in the keys, as well as for a fairly spacious glass touchpad. You’re also getting 4x speakers on this model, even if this chassis lacks the hinge-speaker implemented in the Yoga 9i 2-in-1 and the Yoga Book 9i, so the audio quality isn’t quite as good.

The IO is somewhat sacrificed on the entire Yoga 9i lineup, with USB-C Thunderbolt 4 ports, a single USB-A and an audio jack. It should be fine, as at least you’re getting that USB-A and don’t have to constantly rely on adapter or an external dock.

The display on this series is OLED, 14-inch and 16:10 format, with touch and with a 4K 120Hz PureSight Pro OLED panel. The specs mention up to 750-nits of peak brightness, but I’m not sure what exactly to take out of that, since the sustained OLED brightness isn’t nearly as high. Sustained brightness should be around 400-nits, as on most OLED laptop screens. Other than that, this is amazing display, with crystal sharp resolution and beautiful image quality.

What’s particularly interesting about this series is the lack of any sort of notch above the display that would normally house the cameras and mics on most other Yogas. Instead, the camera is somehow integrated behind the display, with the camera cut put into the display in its top middle part, in order to minimize that top bezel and the laptop’s overall size. Not sure exactly how that works in real use, but I’d reckon it should be less distracting than the larger camera notch on MacBooks.

And speaking of bezels, the side and bottom ones are tiny as well, giving this series a 98% screen-to-body ratio, the highest of any laptops that I know of.

 Yoga 9i 2-in-1 Aura Edition

The Yoga 9i 2-in-1 is a convertible format with a 360-degree display and that well known hinge that includes speakers in it. The chassis is a little larger than on the Slim 9i, and a little heavier as well, but still plenty portable at around 3 lbs and 12.4 x 8.65 in footprint.

The design language is otherwise similar between the clamshell and the 2-in-a variants, with an all metal construction and shiny rounded edges (which should be treated well, as otherwise tend to show scratches fairly easily). The inputs and the IO are just the same as well.

However, Lenovo offers the 2-in-1 Yoga 9i in two different color options, Luna Grey and Cosmic Blue. We’ve reviewed the Blue variant of the previous generation in this article, but both are beautiful and rather unique colors.

The display on the Yoga 2-in-1 is a different panel as well, still OLED at 120Hz, but 2.8K resolution and brighter at 500-nits sustained and 1100-nits peak. I’d argue this makes even more sense on this sort of laptop, as it’s sharp enough, potentially brighter, and slightly less taxing on battery.

The Yoga’s screen also comes with a digitizer, which adds that extra graininess noticeable on light background on OLEDs. It also comes with a pen included in the box, which can be stowed magnetically on the back of the display, near the camera notch. And yes, there’s a camera notch on this series, as the camera in the display integration is only offered on the Slim model.

Now, as far as the specs go, both these laptops are built on Intel Lunar Lake hardware with up to a Core Ultra 7 258V processor and 32 GB of on-chip memory, alongside SSD gen4 storage and a 75 Wh battery.

As we know by now from our reviews, Lunar Lake is not a performer in sustained CPU loads by any means, as it’s a hybrid design with only 8 Cores and 8 Threads, so is in fact a step-back in CPU performance over the Meteor Lake Core Ultra hardware implemented in the previous 2024 Yogas. Instead, Lunar Lake is meant for daily use and multitasking, and comes with competent Intel Arc graphics.

Of course, its overall performance is dependent on the power settings and implemented cooling. The Yoga 9i 2-in-1 bundles a fairly advanced cooling module for this segment, with two fans and hefty heatpipes, allowing for 38W of sustained power in taxing loads on the past generation. That would be plenty to run the Lunar Lake hardware and full load, although the settings are most likely touched down a little bit on this generation, in order to keep temperatures and noise levels at bay. That’s backed up by the fact that this 2025 Yoga generation comes with a 65Wh charger, while the previous model came with a 100W charger instead.

For what is worth, the existing Yoga Slim 7i Aura Edition runs the same Core Ultra 7 258V hardware at 30W, with similar dual-fan cooling, allowing for sub 40 dBA fan noise in sustained loads. I’d expect about the same for the Yoga 9i 2-in-1 as well.

Not sure whether the Yoga Slim 9i implements the same kind of cooling as the Yoga model, since that’s a more compact chassis; it’s something we’ll need to look into for our reviews.

Battery life should be excellent on these laptops, at 8-12 hours of daily use and 15+ hours of video streaming. With some advantage for the convertible model, as the clamshell gets that 4K panel that takes a small tall on battery runtimes.

Now, as far as pricing and availability go, both the Slim 9i and the 9i 2-in-1 Aura Edition will be available in stores around February 2025, starting at $1849 for the clamshell version and $1599 for the convertible. Not sure if that’s for the 258V configuration with 32 GB of RAM or not, but overall rather high MSRP price tags, considering the prices of other premium Lunar Lake laptops such as the Zenbook S 14 and even the Dell XPS 13 nowadays. I’d reckon discounts will follow quickly.

2025 Lenovo Yoga Book 9i 14 gen 10 (vs. 2023 Yoga Book 9i 13)

This 2025 Yoga Book 9i is a refinement of the original Book 9i launched two years ago.

It now implements slightly larger 14-inchy displays, Intel Lunar Lake hardware and a bigger battery, so its footprint has gone up in size a little bit, but the weight is actually notably lower somehow.

The laptops is still a dual-display design with an all metal build and a convertible hinge with speakers in it, similar to the one implemented in the regular Yoga 9i 2-in-1. In fact, the two variants are a lot more alike in these generations as they were in the past.

The dual-display chassis allows for a multitude of use cases, with or without the attachable keyboard accessory. That’s a Bluetooth keyboard that works independently from the laptop. A pen is included as well, as both screens support touch and implement a digitizer. The panels are 14-inch 2.8K OLEDs on both sides.

The keyboard folio lacks a touchpad, which is perhaps why Lenovo bundle a mouse with this Book 9i, alongside that pen.

A folio with a touchpad makes more sense for this format as far as I can tell based on past experience with other dual-screen notebooks such as the Zenbook Duo. I also prefer Asus’s design that allows to stow the keyboard in-between the screens for transport – on the Yoga the screens fold up one over the other, and the keyboard packs up separately. That means you’ll have to be extra careful not to fold this close while having the keyboard on the laptop, as it might put unwanted pressure on the panels. The displays are protected by a layer of glass, but there’s only so much that can prevent.

The hardware on the Yoga Book 9i is the same Intel Lunar Lake platform with up to 32 GB of RAM and 1 TB of SSD storage, alongside an 88 Wh battery.

The power settings are lower on this model compared to the other Yoga 9is, since the cooling is miniaturize as well, but the overall performance should improve across the board from the Core i7-1355U initial configuration. Nonetheless, this is merely a laptop for casual use and  general multitasking, so make sure you come at it with the right expectations.

Runtimes are not going to be as impressive as on the regular Yogas either, since the battery needs to sustain two displays, despite the hefty size of the two combined batteries at 88 Wh. You can switch one off, though, when looking to maximize efficiency, and that should easily get you 10+ hours of mixed use on a charge.

As far as pricing and availability go, the Yoga Book 9i gen10 is expected in stores around March 2025, starting at $1999. That’s about what I’d expect from this sort of device that demands a premium over more traditional designs.
