It additionally features a folio stand.

We have now speculated about this laptop computer’s potential, however after utilizing it for some time, we will lastly draw real-world conclusions and share our findings and opinions. Are the twin screens price it? Discover out now.

Specs Highlights

  • thirteenth Technology Intel Core i7-1355U Processor
  • Built-in Intel Iris Xe Graphics

  • WiFi 6E* 802.11AX (2 x 2)
  • Beginning at 1.34kg / 2.95lbs
  • Bluetooth keyboard and mouse included. Lenovo Digital Pen 3 stylus included.


The Lenovo Yoga E-book 9i is exceptional for its sustainability and design ingenuity. It has a Carbon Impartial Certification, using eco-friendly supplies like 90% recycled plastic within the energy adapter case and 100% recycled aluminum within the high cowl. The hanging Tidal Teal (metallic blue) coloration provides vibrancy, departing from the standard gray or silver tones.

Like Lenovo’s Yoga 9i series, the Yoga E-book 9i options curved edges for enhanced grip and luxury. Its groundbreaking dual-screen design, a world-first for 2-in-1 laptops, improves productiveness with multitasking capabilities. At 0.63 x 11.8 x 8 inches (15.95mm x 299.1mm x 203.9mm) and 2.95 lbs (not counting the included mouse and keyboard), it balances portability and performance.

As you may think about, the twin screens facilitate seamless multitasking and different prospects, however we’ll get to that later. The included machine’s stand doubles as a canopy for the removable keyboard and stylus. It’s vital to notice that the kickstand supplies stability solely on flat surfaces like desks or tables. You may, after all, use the pc as a daily clamshell laptop computer after all.

The inclusion of the Tidal Teal folio/stand enhances the machine’s aesthetics whereas offering sensible help and safety.

Keyboard, Pen, Mouse and digital inputs

The Yoga E-book 9i’s Bluetooth keyboard supplies customers a compact but practical typing expertise. Regardless of its compact dimension, the keyboard retains important Perform keys, making certain customers can entry key options and instructions conveniently.

There’s an undersizing of the up and down arrow keys, a deliberate adjustment to accommodate the machine’s total chassis. This design choice maintains the machine’s smooth profile whereas offering tactile suggestions and value for directional inputs. Along with the keyboard, the Yoga E-book 9i features a compact mouse, akin to a journey mouse.

I discovered the bodily keyboard inferior to the built-in keyboards on high-end Yoga laptops. Lenovo needed to make this one as skinny as attainable, so it won’t have the very best key switches and tactile suggestions. Should you’re on the lookout for a high-performance journey keyboard, have a look at the Logitech MX Mechanical Mini.

The Lenovo Digital Pen 3 included with the Yoga E-book 9i provides customers a snug and responsive stylus expertise. It really works on each screens and is superb for taking notes or fundamental sketching. You would possibly want one thing else for skilled functions, but it surely’s not apparent if fancier Lenovo pens are appropriate with these screens.

Each Pen and Mouse require AAA and AA batteries, respectively, and will not be rechargeable. The Keyboard has a USB-C connector for charging.

A digital keyboard and digital trackpad can be found when not utilizing the bodily keyboard. Every can occupy as much as half of the underside display screen, whereas content material is offered on the highest display screen. That’s far more display screen area than you’d get on even the biggest pill. The digital keyboard expertise was advantageous, however the trackpad doesn’t really feel pretty much as good and correct because the bodily one. As a substitute of the trackpad, I desire utilizing the twin touch-screens each time attainable.

Lenovo has customized software program known as Yoga E-book 9 Consumer Middle to tweak varied consumer expertise settings, from Window administration and dual-screen gaming to digital keyboard settings. It could assist make the laptop computer yours.


The pc boasts three USB Sort-C Thunderbolt 4 connectors, a flexible characteristic providing high-speed knowledge switch, extensions, and charging capabilities. All three ports help charging, making certain handy energy entry wherever you go. One Thunderbolt 4 connector is positioned on the left edge, whereas the remaining two are positioned on the proper, offering flexibility for peripheral connections.

Notably absent are conventional USB-A ports and a headphone jack. Thankfully, the 65W AC energy provide connects to USB-C, streamlining energy administration and lowering muddle. Relying in your wants, you would possibly contemplate a USB-C HUB with further ports equivalent to USB-A, HDMI, and extra. They’re moderately cheap.

Sound high quality

The Lenovo Yoga E-book 9i integrates Dolby Atmos expertise with Bowers & Wilkins audio system, providing a stellar audio expertise. Its 360-degree rotating sound bar delivers immersive sound high quality. The system impresses with better-than-average bass and clear sounds on different frequencies.

The Dolby Entry software program provides versatility with music, films, video games, dynamics, and voice presets, together with an equalizer for personalised changes. With its loud, bass-heavy audio output, the Yoga E-book 9i guarantees an amazing leisure expertise, making it a best choice for customers who prioritize superior sound efficiency of their multimedia units. The sound bar is positioned proper in entrance of the consumer, the absolute best location to maximise the accessible sound power.


This pc stands out for its glorious efficiency and visible expertise. That includes two similar 13.3-inch OLED touchscreens with a decision of 2.8K (2880 x 1800), customers can count on gorgeous readability and element of their content material.

With a brightness of 400 Nits, the shows guarantee vivid and vibrant colours, even in well-lit environments. The 16:10 side ratio provides a wider viewing space, superb for productiveness and multimedia consumption. Furthermore, the show covers 100% of the DCI-P3 coloration gamut, producing correct and lifelike coloration for professional-grade content material creation and multimedia enhancing.

The inclusion of Dolby Imaginative and prescient HDR additional enhances the visible expertise by delivering richer distinction and deeper blacks.

The one factor we’d instantly ask Lenovo to “enhance” right here is to construct a 16″ and even 18″ model of this laptop computer to extend the show space additional, which is the first worth of the modern laptop computer.

The opposite factor Lenovo ought to contemplate is video enter by way of USB or mini-HDMI. This laptop computer may very well be a standalone dual-display for an additional pc, console, and many others. It’d lose a few of its computing worth because it ages, however the show’s lifespan might be 4X longer than its computing one.

Twin-Show Consumer Expertise

The distinctive twin show setup can be utilized in some ways, some apparent and a few… “inventive. ” Lenovo has accomplished an amazing job pitching what it thinks you are able to do with it, and I’ve embedded a video under. Right here, I’ll deal with use instances that resonate with me: productiveness and Leisure.

We will most likely all agree that having a 100% further show floor is an efficient factor, and we already know it’ll make everybody extra productive. Much less Window and Process switching, data accessible at a look, and many others. Superb. Signal me up.

I additionally usually do gentle work, equivalent to catching up with emails or looking for data whereas having YouTube, music, or a TV present taking part in on the opposite display screen.

Lastly, taking written notes with the Stylus throughout on-line assembly calls has by no means been simpler and extra snug. I usually try this on an iPad mini 6, however the 13.3 display screen(s) is rather a lot higher due to the digital paper dimension.

Typically, I contemplate this laptop computer greatest utilized in a set location, equivalent to your resort room, cafe, and many others, throughout your travels. Its compact dimension and lightweight weight make it simple to move even with an exterior mouse and keyboard. If you want to use the laptop computer for 10 minutes right here and there, you would possibly wish to have a look at the ThinkPad X1 nano gen2 (which is phenomenal) or a Lenovo Android tablet.

Listed below are extra use instances as Lenovo envisions them. See when you join with a few of them:


This 5MP webcam has handy options and high-quality efficiency within the laptop computer market. It may be turned OFF utilizing the bodily shutter button for added privateness, making certain the webcam received’t by chance activate.

In portrait mode, the webcam is completely positioned in entrance of the consumer’s face: the absolute best angle. Its microphone delivers clear audio, complementing its good video capabilities. Unsurprisingly, a bigger standalone microphone would ship increased recording efficiency if you want to seem on podcasts.

With a video decision of as much as 1440p and 30 frames per second, it ensures moderately sharp and clean video even in reasonably lit environments. The built-in Home windows Whats up facial recognition help allows seamless biometric login, including a layer of comfort and safety for customers. Sadly, there isn’t any fingerprint reader.

System Efficiency

Outfitted with an Intel Core i7-1355U (1.70 GHz), 16GB of RAM, and a 512GB SSD, this pc can deal with workplace productiveness and multimedia duties with ease and quietly. Conceptually, it is also a superb internet improvement system due to the big show floor. Nonetheless, when you rely closely on Docker containers, you may want a system with extra RAM.

The U-series Intel core processors are designed for energy effectivity quite than efficiency. With two shows utilizing a big quantity of energy, one thing needed to give, and total, it’s a superb tradeoff between growing usability and acceptable efficiency.

The identical factor is true for storage efficiency. It’s nice for the use instances we suggest (productiveness, leisure) with this laptop computer, however within the grand scheme of issues, benchmarks equivalent to 3DMark Storage Benchmark classify this pc’s storage efficiency as barely under common.

Geekbench 5: 1743 (Single). 7202 (Multi), 18751 (OpenCL)
Geekbench 6: 2457 (Single), 8171 (Multi), 14454 (OpenCL)
3DMark TimeSpy: 1679

Battery Life

The 80Wh battery capability is comparatively massive for a sub 3 Lbs laptop computer, and with it, this laptop computer can final ~9 hours in a regular benchmark equivalent to PCMark 10 trendy workplace.

Clearly, having two screens just isn’t a bonus relating to battery life benchmarking, particularly if mentioned screens have a 2.8K decision. Whereas yow will discover laptops that rating increased (14+ hrs) in that exact benchmark, it’s apparent that absolute battery life isn’t a precedence for potential patrons who’re probably to make use of this pc on a desk.

Nonetheless, if you wish to apply it to the go (in-flight, and many others.), you continue to have a good battery life, due to the low-power CPU alternative.


The Lenovo Yoga E-book i9 satisfies a particular want: maximizing the accessible show space to extend consumer productiveness. Numerous research have confirmed that having extra screens results in drastic productiveness features, and we all know this very effectively since we journey with a ThinkVision M14 / M14D or ThinkVision M15.

This Yoga E-book i9 makes lugging a conveyable show a factor of the previous, or it may take our current setup to the following degree by working alongside one in all these cellular shows. This will depend on how a lot gear you wish to carry. Moreover, its 360-degree hinge permits extra use instances, making it a really versatile pc.

This dual-display emphasis has a price: that is not an affordable pc or one that gives glorious computing worth (efficiency per greenback spent). If that’s what you need, there are higher choices elsewhere, with Lenovo or in any other case. However when you really feel cramped inside your present laptop computer show, this pc may unlock your productiveness instantly.
