Since its launchThe Lenovo Yoga Book i9It has inspired the imagination and desire of many PC users. It was the first true OLEDDual-screen laptop which has been copied since by competitors. The laptop includes a Bluetooth keyboard that can be detached, a stylus and a computer mouse. The laptop also comes with a folio.

We have speculated about this laptop’s potential, but after using it for a while, we can finally draw real-world conclusions and share our findings and opinions. Is the dual screen worth it? Find out more now.

Highlights of the Specs

It is Carbon Neutral Certified, and uses eco-friendly material such as 90% recycled polymer in the power adapter’s case and 100% recyclable aluminum in the top. The Tidal Teal color (metallic blue), which is a departure from the usual grey and silver tones, adds vibrancy.

Like Lenovo’s Yoga 9i seriesThe Yoga Book 9i has curved edges that enhance grip and comfort. Its dual-screen design, which is a first in the world for 2-in-1 computers, increases productivity and multitasking. The dimensions of the laptop are 0.63 x 11.8, x 8 inches (15.95mm, 299.1mm, 203.9mm). 2.95 lbsIt balances portability with functionality (without the mouse and keyboard included).

As you can imagine, the dual screens facilitate seamless multitasking and other possibilities, but we’ll get to that later. The included device’s stand doubles as a cover for the detachable keyboard and stylus. It’s important to note that the kickstand provides stability only on flat surfaces like desks or tables. You can use the computer like a regular laptop.

The inclusion of the Tidal Teal folio/stand complements the device’s aesthetics while providing practical support and protection.

Keyboard, Pencil, Mouse, and Virtual Inputs

The Yoga Book 9i’s Bluetooth keyboard provides users a compact yet functional typing experience. The keyboard is compact, but still retains the essential Function keys. This allows users to access key features and commands easily.

There’s an undersizing of the up and down arrow keys, a deliberate adjustment to accommodate the device’s overall chassis. This design decision maintains the device’s sleek profile while providing tactile feedback and usability for directional inputs. The Yoga Book 9i comes with a compact mouse that is similar to a travel-sized mouse.

The physical keyboard is inferior to those built into the high-end Yoga Laptops. Lenovo wanted to make it as thin as possible so it may not have the best tactile feedback and key switches. If you’re looking for a high-performance travel keyboard, look at the Logitech MX Mini Mechanical.

The following are some of the ways to get in touch with each other: Lenovo Digital Pen 3 The stylus included with the Yoga Book 9i provides users with a comfortable and responsive experience. It is great for basic sketching or taking notes. You might need something else for professional applications, but it’s not obvious if fancier Lenovo pens are compatible with these screens.

Both Pen and Mouse use AAA and AA Batteries, respectively. They are not rechargeable. The Keyboard can be charged using a USB Type-C connector.

When using the keyboard, you can use a virtual trackpad and keyboard. Each can occupy as much as half of the bottom display, while the content is displayed on the top. That’s much more screen space than you would get on even the largest tablet. The virtual keyboard was great, but the trackpad did not feel as accurate and good as the physical one. Instead of using the trackpad I prefer to use dual touch-screens when possible.

Lenovo has a custom software program called Yoga Book 9 User CenterYou can customize your user experience by adjusting settings ranging from window management, dual-screen gaming and virtual keyboard settings. It can help you personalize your laptop.


The computer boasts Three USB Type C Thunderbolt 4Connectors offer a variety of features including high-speed transfer of data, extension and charging. All three ports are capable of charging, providing convenient power wherever you are. The left edge has one Thunderbolt 4 connector, while the other two are on the right. This allows for flexibility in peripheral connections.

The traditional USB-A port and the headphone jack are both missing. The 65W AC power supply is connected to USB-C. This simplifies power management and reduces clutter. You might want to consider a USB HUB that has additional ports like USB-A, HDMI and more. They are affordable.

Sound quality

The Lenovo Yoga Book 9i includes a touchscreen. Dolby Atmos technology with Bowers & Wilkins speakers, offering a stellar audio experience. The 360-degree rotating soundbar delivers immersive sound. The system is impressive with its clear sound and better than average bass.

Dolby Access is a software that adds flexibility with music, movies and games, as well as voice presets. It also includes an equalizer to make personalized adjustments. The Yoga Book 9i offers a great audio experience with its loud, bass heavy output. It is a top pick for users who value superior sound quality in their multimedia devices. The sound bar is positioned directly in front of the user to maximize sound energy.


This computer is known for its outstanding performance and visual experience. Featuring Two 13.3-inch OLED touchscreens that are identicalWith a resolution of 2.8KUsers can expect to see stunning clarity and detail when they upload content in the 2880 x 1800 resolution.

Brighten up your day with a brighter shade 400 Nits, the displays guarantee vivid and vibrant colours, even in well lit environments. The 16:10 ratio provides a larger viewing area for productivity and multimedia consumption. The display also covers a wider viewing area. The DCI-P3 color gamut is 100%.Producing accurate, lifelike color for professional content creation and multi-media editing.

Dolby vision is included as standard. HDRFurther enhances the visual experience with richer contrasts and deeper blacks.

We would ask Lenovo only to do one thing. “improve” here is to build a 16″ or even 18″ version of this laptop to increase the display area further, which is the primary value of the innovative laptop.

The other thing Lenovo Consider video inputVia USB or mini-HDMI. This laptop could serve as a dual display for another computer, console etc. It might lose some of its computing value as it ages, but the display’s lifespan is probably 4X longer than its computing one.

Dual-Display User Experience

The unique dual display setup can be used in many ways, some obvious and some… “creative. ” Lenovo has done a great job pitching what it thinks you can do with it, and I’ve embedded a video below. Here, I’ll focus on use cases that resonate with me: productivity and Entertainment.

We can all agree on the fact that a 100% additional display surface will be a good thing. Everyone can be more productive. Less window and task switching, information at a quick glance, etc. Amazing. Sign me up.

I also like to do light tasks, such as checking my emails, browsing the web, or watching a show or music while YouTube is playing.The other screen.

Finally, taking written notesIt’s never been easier or more comfortable to use the Stylus for online meetings. I usually do this on an iPad Mini 6, but the 13.3-inch screen(s) are much better because of the paper size.

In general, I think this laptop is best used in a fixed place, such as a hotel room, café, etc., while you are traveling. Its small size makes it easy for you to transport, even if you use an external keyboard and mouse. You might want to consider the Laptop if you only need to use it for 10 minutes at a time. ThinkPad X1 nano gen2(which is phenomenal or a) Lenovo Android Tablet.

Here are some more use cases that Lenovo has in mind. Check out these use cases to see if they resonate with you.

In portrait mode the webcam is Perfectly positioned in front of the user’s face: the best possible angle. Its microphone delivers clear audio, complementing its good video capabilities.

The integrated Windows Hello facial recognitionSupport for biometric authentication adds convenience and security to users. Unfortunately, there isn’t fingerprint reader.

System Performance

Equipped with a Intel Core i7-1355U (1.70%). GHz), 16GB of RAM, and a 512GBThis computer is able to handle office productivity tasks and multimedia tasks quietly and with ease. Conceptually, the large display area could make it a good web-development system. If you are heavily reliant on Docker containers you may need a system with more memory.

The U-series Intel processors are designed to be more power efficient than they are for performance. With two displays using a significant amount of power, something had to give, and overall, it’s a good tradeoff between increasing usability and acceptable performance.

Storage performance is no different. It’s great for the use cases we recommend (productivity, entertainment) with this laptop, but in the grand scheme of things, benchmarks such as 3DMark Storage Benchmark classify this computer’s storage performance as slightly below average.

Geekbench 5: 1743 (Single). 7202 (Multi), 18751 (OpenCL)
Geekbench 6: 2457 (Single), 8171 (Multi), 14454 (OpenCL)

Battery Life

The following are some of the ways to get in touch with each other: 80Wh Battery CapacityIt is a large laptop for a laptop that weighs less than 3 lbs. With it, the laptop can run for up to 9 hours using a standard benchmark, such as PCMark 10, modern office.

Two screens are not an advantage for battery life benchmarking. This is especially true if the screens have a resolution of 2.8K. While you can find laptops that score higher (14+ hrs) in that particular benchmark, it is obvious that absolute battery life isn’t a priority for prospective buyers who are likely to use this computer on a desk.

If you need to use it while on the move (in-flight etc. ), then this is not a problem.The low-power processor choice allows for a good battery life.


The Lenovo Yoga Book i9 is designed to meet a specific need, which is to maximize the display area in order to increase user productivity. Numerous studies have shown that having multiple monitors can lead to dramatic productivity gains. We know this because we travel with a ThinkVision M14 / M14DThinkVision M15.

This Yoga Book i9 could make lugging a portable screen a thing of past or replace our current setup Next levelBy working alongside these mobile displays. How much equipment you are willing to carry will determine the answer. The 360-degree hinge makes it very versatile.
