Lenovo Yoga Book 9i Review: A Promising Dual-Screen Laptop for Productivity

The Lenovo Yoga Book 9i introduces a unique dual-screen design that offers enhanced productivity and versatility. With two 2.8K OLED screens and a polished form factor, this laptop demonstrates the potential of a future laptop experience. This review delves into the device’s design, performance, battery life, and overall user experience, highlighting its strengths and weaknesses.

Design and Build

The Lenovo Yoga Book 9i boasts an appealing design, featuring an all-aluminum matte exterior with a beautiful shade of teal. The minimalistic Lenovo Yoga branding and glossy side rims add a touch of elegance. The 13-inch laptop’s compact size and lightweight nature make it highly portable. The standout feature is the speaker hinge, which not only supports various usage modes but also ensures consistent sound quality.

Dual-Screen Functionality

The dual-screen functionality of the Yoga Book 9i sets it apart from conventional laptops. The two 60 Hz, 2.8K OLED screens offer a spacious and productive working environment, ideal for tasks such as web browsing and content creation. The 16×10 aspect ratio enhances the viewing experience and provides comfortable orientation in both laptop and vertical configurations. The high resolution and OLED technology deliver vibrant colors and excellent contrast, though the anti-reflection coating could be improved for better visibility in brighter environments.

Keyboard and Trackpad

The Yoga Book 9i comes with a separate keyboard that attaches magnetically to the bottom screen. While the keyboard is functional, its thinness affects the typing experience. The inclusion of a trackpad on the bottom screen is responsive but lacks the smoothness of traditional glass trackpads. For extended use, a mouse is recommended. The keyboard cover also doubles as a stand, providing a comfortable working angle for prolonged periods.

Performance and Battery Life

Equipped with an i7 1355U CPU, the Yoga Book 9i delivers decent performance suitable for most tasks. However, compared to competitors like the M2 MacBook Air, its performance falls short, especially when unplugged. The device’s battery life, surprisingly, holds up well due to the low-power U-series CPU and an 80 watt-hour battery. The laptop lasts over six hours on a single charge, but it falls behind the M2 MacBook Air’s impressive 10-hour battery life.

Productivity and Software

Lenovo has implemented software that supports seamless dual-screen workflows, allowing users to move windows between screens effortlessly. The ability to span a window across both screens proves useful for reading long documents or multitasking. The device’s unique features, such as lock screen notes and quick screenshots, enhance productivity. However, the absence of a physical connection between the keyboard and the device, as well as the limited widget customization options, leaves room for improvement.


The Lenovo Yoga Book 9i presents an intriguing dual-screen concept with the potential to revolutionize the laptop experience. Its elegant design, vibrant OLED screens, and flexible usage modes contribute to enhanced productivity. However, the device’s performance, while suitable for typical tasks, falls short compared to competitors. The keyboard and trackpad, though functional, have room for improvement. With a competitive price point and a focus on productivity, the Yoga Book 9i offers a promising glimpse into the future of laptops.
