Lenovo Yoga Book 9i: Two-minute review
The Lenovo Yoga Book 9i solves a problem for that small subset of users always frustrated with the limited amount of screen most laptops offer. And while using an external monitor is the easiest and most mainstream way to solve that problem, you’re either dealing with one that stays at home, or is an extra item to carry with you as is the case with the best portable monitors.
The Lenovo Yoga Book 9i then is probably among the best laptops for those who want to be able to compose an email or article without having to switch over to a different window to look something up. It’s also great for anyone looking to do some light photo editing that feels restricted on a regular notebook.
Though it’s among the best Ultrabooks, in my estimation at least, it’s not the most powerful. Since it utilizes integrated graphics, it’s not quite there for those hoping to also edit videos on the road. And that’s a pity considering the price tag that this comes with, but that’s also the price you pay for having two gorgeous screens, a chic aesthetic, and a bunch of accessories that can turn this laptop into a pseudo-desktop experience.
Basically, this laptop is a fantastic computer experience that some will absolutely love and most will find to be too much computer. For me, it’s just about perfect.
Lenovo Yoga Book 9i: Price and availability
- How much does it cost? Starting at $1,980 / £1,965 / AU$4,499
- When is it available? Available now
- Where can you get it? Available in the US, UK and Australia
In short, the Lenovo Yoga Book 9i is expensive. Yes, you’re paying for not one, but two OLED touchscreens with high resolutions, as well as the unique form factor. There’s also been plenty of care put into its design and aesthetics, not to mention that it comes with a Bluetooth keyboard, mouse, and stylus along with a keyboard carrying case that turns into a stand.
But, its under-the-hood specs are not that of a $2,000 / £2,000 computer, so it does feel overpriced, even if OLED panels are going to increase the price of any computer that they come with. At least, the upgrades are fairly benign as going from 16GB of RAM to 32GB is $57 difference and going from a 512GB to a 1TB SSD is just $30.
Of course, if you’re in the UK, you have to accept both upgrades in tandem, but it’s only a £55 difference. If you’re in Australia, you’re unfortunately limited to the most basic model.
Currently, there’s really only one laptop to compare the Lenovo Yoga Book 9i to (discounting its previous iteration that’s basically the same thing with a slightly weaker processor and different port selection). That laptop is the ASUS Zenbook Pro 14 Duo OLED. It starts at basically the same price point – $1,999.99 / £1,999.99 (about AU$3,134.28) – but has a slightly different approach to the whole two-screen setup, where one is smaller than the other and you can’t switch between a landscape and portrait mode like you can with the Yoga Book 9i. If you want to a deeper dive between the two models, we did put the Asus Zenbook Pro Duo and the Yoga Book 9i’s previous version in a head-to-head comparison.

Lenovo Yoga Book 9i: Specs
The Lenovo Yoga Book 9i is fairly limited in upgrades. There’s just one CPU, the Intel Core Ultra 7 155U, as well as its integrated graphics on offer. The only real customizations or upgrades available are with the RAM and SSD, where you can choose between 16 or 32GB and 512GB or 1TB, respectively.
Lenovo Yoga Book 9i: Design
- Gorgeous inside and out
- Comes with bluetooth keyboard, mouse, and stylus
- Limited amount of ports
Whether opened or closed, the Lenovo Yoga Book 9i is gorgeous. Its metallic Tidal Teal colorway covers not only the outer shell of the laptop itself, but the Bluetooth keyboard, mouse, and stylus that come with. The whole setup is almost as pretty as its two bright, vibrant OLED screens, connected by a thin panel housing the dual two-watt speakers.
Speaking of, those panels are touch-sensitive. This allows you to interact with it digitally (as in your fingers), with the stylus, or to place it in “laptop mode” so that the lower screen sits where a keyboard would typically sit. This way, you don’t have to carry all the extras with you if you don’t. You would just use a particular eight-finger tap gesture to pull up a virtual keyboard.
To go along with the touchscreens, this is essentially a 2-in-1 notebook, so you can flip into tablet mode, which disengages one of the screens, or place it in tent mode, etc. However, I prefer using the stand, which doubles as the keyboard cover and carrying case to prop up the two screens. You can use the Lenovo Yoga Book 9i in either landscape mode, where one screen sits atop the other, or in portrait mode, where they’re side-by-side. I prefer the former, though I can see the latter being very useful to programmers or anyone needing to see two different windows next to each other.
It’s a unique experience, really only hampered by its price. And while I’ve heard of some having issues with the previous generation when in laptop mode, because programs would pop up in front of the virtual keyboard, I have not had that happen to me.
Laptop mode really only falls short insofar that using a virtual keyboard kind of stinks. There’s no tactile feedback and you’re probably going to have to look at it to know where all the keys are. At least it pulls up a virtual trackpad as well.
The Bluetooth accessories, however, are a pleasure to use. The keyboard is compact and clips on to the stand magnetically to stay stable. And though it’s tiny, its keys are not, so I never felt cramped typing on it. It’s not going to match up with the best mechanical keyboards, but it’s good enough to type up this article.
The mouse is fairly minimalist, but works as needed, not to mention feels fairly accurate. It also has the added benefit of being able to wirelessly connect to two devices, so you can use it with other laptops or computers if you like.
While I’m not a big stylus user, it was nice to the touch – they all have that textured aluminum feel - and seemed responsive during use.
The port selection here is a little bit of a letdown, especially considering that the previous iteration had a decent amount of variety. This version of the Lenovo Yoga Book 9i falls squarely into the MacBook Air-style less is more camp with its three Thunderbolt 4 ports. There’s not even a headphone jack.
As far as physical controls go, there are just two – a power button and a privacy shutter button, the latter of which I appreciate being included.

Lenovo Yoga Book 9i: Performance
- Great for day-to-day tasks, not so much for demanding ones
- Two equally visually stunning screens
- Surprisingly good sound for a laptop
Here's how the Lenovo Yoga Book 9i performed in our suite of benchmark tests:
3DMark: Fire Strike: 4921; Time Spy: 2208; Night Raid: 18128
GeekBench 6.2.2: 2317 (single-core); 8887 (multi-core)
25GB File Copy: 16.37
Handbrake 1.6.1: 9:23
CrossMark: Overall: 1361 Productivity: 1386 Creativity: 1391 Responsiveness: 1206
Sid Meier's Civilization VI: Gathering Storm (1080p): 19.421 fps
Web Surfing (Battery Informant): 7:38:10
When it comes to the Lenovo Yoga Book 9i’s performance, it’s quite excellent for day-to-day tasks, powered by the Intel Core Ultra 7 155H and 16 or 32GB of RAM. I was able to have multiple tabs open at once, including having streaming video playing at the same time as I was doing work.
But, since it just has integrated Intel Arc graphics, it can’t do a whole lot of heavy lifting. If you think of this laptop as a unique Ultrabook with extra screen real estate, that’s not really an issue. If you want to do demanding tasks, such as video editing, you’re not really going to do it.
While you can certainly take a look at our benchmarks to confirm this, I did a little testing with video games. I found out that this laptop even struggles with older titles. Consider the fact that it manages under 20 fps in Sid Meier's Civilization VI.
Now, no one looking at this computer is going to think "gaming laptop," but it’s just a good way to test how much power this laptop has. If you do photo editing, you’ll be fine as long as you’re not converting or editing batch files. If you want to do video editing, this is probably not the way to go.
And that’s a shame because the two 13.3-inch OLED screens look so good. Not only does it have color coverage of 191.2% sRGB and 135.4% DCI-P3 through testing (Lenovo actually rates it 100% DCI-P3), but it has an incredibly accurate screen with a Delta E < 0.27 (the closer to zero the better).
The screens also have a VESA-certified DisplayHDR True Black 500 rating, so the contrasts in shadows really pop out. Both screens are pretty bright at 400 nits. If you want superlatives, the two panels look gorgeous, with an eye-poppingly wide range of colors.
Surprisingly, the sound quality is pretty good for a laptop. No, it’s not going to compete with external speakers, but typically laptop speakers sound hollow and like they’re coming from a small, thin box (because they are). Here, the sound is actually fairly full, just missing some low end.
If you’re considering this laptop for work and do a lot of video conferencing, know that the webcam is pretty sharp, though not the smoothest with a 1440p resolution at 30Hz.
Lastly, like every laptop these days, you have some AI functionality such as Copilot built in. The AI elements that anyone will notice are more of a Windows thing, and is still somewhat half-baked, so don’t use that for too much consideration when looking at this laptop.
- Performance: 4.5 / 5
Lenovo Yoga Book 9i: Battery life
- Decent but not great battery life
- Slight drop in battery life going from laptop mode to dual-screen
When one thinks of Ultrabooks these days, long battery life is usually a given. However, with the Lenovo Yoga Book 9i, you can’t quite expect to get 13 or 14 hours of use on a single charge. And if you think about it, it’s not surprising given that it’s powering two screens. On top of that, in my (anecdotal) experience, OLED panels seem to require a little more juice.
Still, the seven and a half hours that it can reach up to in laptop mode is pretty decent when keeping that in mind. The battery life drops down to six hours and 45 minutes in two screen mode, which is surprisingly minimal. You need to remember, however, that the second screen is still on and in use in this mode, though it’s usually just showing the virtual keyboard instead of something more active or vibrant.
- Battery life: 4 / 5

How I tested the LenovoYoga Book 9i
- Tested for three weeks
- Used it for work, gaming, and streaming
- Used it in different modes
I used the Lenovo Yoga Book 9i for three weeks in a number of different ways. I broke it out it for work, including typing up this review (along with the requisite online research). I used it to stream video. I even did some light gaming, mainly running such as Poirot: The London Cases and Mirror’s Edge: Catalyst (which it basically couldn’t run). I used the different modes to see how the experience would change, played around with the HDR, and took the webcam for a whirl.
After spending time with the Lenovo Yoga Book 9i, it’s clear that this is perfect for those who want extra screen real estate without dealing with an external, portable monitor or those who want something a little different, whether as a status symbol or just something that offers a different experience.
I’ve spent the last few years reviewing tech gear for gaming and otherwise, where I’ve gotten a feel for what to look for and how to put a piece of kit through its paces to see whether it’s worth the recommendation.
