Lenovo IdeaPad Duet 5i Review: Surface Pro on a Budget?

The enduring appeal of hybrid devices is undeniable. In a world where computing needs constantly shift between focused productivity and casual consumption, the 2-in-1 form factor promises the best of both worlds: the power of a laptop blended with the grab-and-go versatility of a tablet. For years, Microsoft’s Surface Pro line has set the gold standard for Windows-based detachables, but that premium experience often comes with a premium price tag.

This brings us to the central question: Can the Lenovo IdeaPad Duet 5i truly deliver a “Surface Pro experience” without demanding that top-tier investment? At Prowell Tech, the mission is to cut through marketing jargon and provide practical, trustworthy advice based on real-world usage. This analysis dissects the Duet 5i with that lens, comparing its strengths and compromises against the established Surface Pro to help determine if it is the right fit for a user’s budget and workflow. The demand for a “Surface Pro on a budget” extends beyond merely seeking a cheaper alternative; it reflects a broader market desire for premium experiences at accessible price points. This trend is driven by improvements in component efficiency and manufacturing, allowing features once exclusive to high-end devices to become more widely available.

The Evolving 2-in-1 Landscape: A Prowell Tech Perspective

The journey of the 2-in-1 has been a fascinating one. Back when Wi-Fi 4 was cutting-edge, early attempts at these hybrids were often bulky, underpowered, and featured finicky hinges that felt prone to failure. Fast forward to today, and the market has matured significantly, driven by a clear consumer need for devices that can truly do it all without breaking the bank.

The 2-in-1 market is now clearly segmented. Premium devices like the Surface Pro continue to push the boundaries of innovation and performance, while budget-friendly options, such as the Lenovo IdeaPad Duet 5i, make the versatile form factor accessible to a much wider audience. The fundamental appeal lies in the “rising demand for versatile and portable computing solutions,” with approximately 45% of consumers showing a preference for 2-in-1 laptops due to their dual functionality, allowing users to seamlessly transition between tasks. However, the “high initial cost of premium models” remains a “significant restraint” for about 25% of potential buyers. These devices, especially those equipped with high-performance specifications, touchscreens, and detachable. As the market overview notes, “Previously, these convertibles were costly. Currently, many options are available, which are affordable”.

This market evolution of 2-in-1s demonstrates a classic technology industry pattern: innovation begins at the high-end with premium models, and over time, these advanced features and form factors become more refined and affordable, expanding into the mainstream. The Duet 5i exemplifies this maturation. The initial high cost of pioneering devices created a barrier, which then fostered an environment where manufacturers could introduce more economically viable alternatives. This progression shows that the Duet 5i is not an anomaly, but a natural development in the 2-in-1 lifecycle, making the versatile form factor accessible to a mass market. This trend suggests that the 2-in-1 is transitioning from a niche, luxury product to a more mainstream computing category, with increasing availability of affordable options likely driving further adoption and innovation, compelling even premium brands to offer more compelling value to justify their higher price points.

Lenovo IdeaPad Duet 5i: Design, Display, and Daily Ergonomics

When first unboxing the Lenovo IdeaPad Duet 5i, its design immediately conveys a sense of purpose and portability.

A. First Impressions & Build Quality

The Duet 5i impresses with a sturdy build and intuitive detachable design. It features a “slim and light” profile, complemented by a “recycled fabric design” on its folio case. This gives it a pleasant tactile feel, making it “well-made and looks good” for its price point. One of its key design strengths, and a preferred approach for many, is the integrated kickstand built into the back of the tablet. This offers superior stability compared to 2-in-1s where the kickstand is integrated into the keyboard, which can often feel flimsier. The tablet itself weighs a mere 809g (1.78 lbs), with the folio case adding 360g (0.79 lbs) , resulting in an “extremely slim and portable” package. While perhaps not as sleek as some premium alternatives, it certainly offers a robust physical design for its category.

B. The Visual Experience

For many, a tablet’s primary function is media consumption, and here, the Duet 5i truly shines. Its 12.35-inch WQXGA (2560 x 1600) LTPS glossy touchscreen is a standout feature. The stunning 16:10 aspect ratio is particularly well-suited for entertainment, combining with Dolby Vision® and Dolby Atmos® for a rich audio-visual experience. The display boasts a “vast color range and 500 nits of brightness” , ensuring “crystal-clear fidelity and accuracy” even in brighter environments. This “magnificent viewing experience” is a clear strength, and Lenovo has even included “Eye Care” technology to limit low blue-light emissions and reduce eyestrain during extended use.

Lenovo’s deliberate choice of a 16:10 aspect ratio for the 2.5K display, with 500 nits brightness and Dolby Vision, suggests a strategic focus on multimedia consumption and visual quality. This differentiates it from the Surface Pro’s 3:2 ratio, which is often optimized for document-centric productivity. The 16:10 aspect ratio is inherently better for widescreen video content, resulting in smaller black bars compared to 3:2. The high brightness and Dolby Vision support further enhance the media experience. This indicates that Lenovo is targeting users who blend work with significant entertainment use, making it a compelling choice for students or casual users for whom entertainment is a key part of their device usage.

C. Connectivity & Ports

Connectivity is straightforward on the Duet 5i. It comes equipped with two full-function USB 3.2 Gen 2 Type-C ports. These versatile ports support power delivery, output to 4K displays, and high-speed data transfers, making them capable for most modern peripherals. Both USB-C ports are conveniently located on the left flank of the tablet, while the right side houses a traditional 3.5mm headphone jack, along with the power button and volume rocker. For wireless connectivity, it supports Intel WiFi 6E and Bluetooth 5.1. However, it is important to note that neither of the USB-C ports has Thunderbolt 3 or 4 functionality, which is a common omission in this budget category.

Actionable Takeaway: The Duet 5i’s design and display are strong points for media consumption and general use, offering a premium feel at a budget price. However, its port selection, while functional, might require a USB-C hub for users with extensive peripheral needs, especially those relying on Thunderbolt.

Performance Under the Hood: More Than Just an i3?

The heart of any computing device lies in its processor and memory. For the Lenovo IdeaPad Duet 5i, these components define its capabilities and set realistic expectations for its performance.

A. Core Components

The standard configuration of the Duet 5i in the US typically features a 12th Generation Intel Core i3-1215U Processor. This is paired with 8GB of LPDDR4x RAM and a 128GB M.2 PCIe SSD. While Lenovo offers configurations with up to a Core i7 globally, the US market primarily sees this Core i3 build. The Core i3-1215U is a U-series chip, meaning it is designed for efficiency with a lower 15-watt power draw , contributing to battery life. Graphics are handled by the integrated Intel UHD Graphics.

Lenovo’s decision to primarily offer the Core i3 configuration in the US market for the Duet 5i, despite global availability of higher-spec models, is a direct strategic choice to hit a specific, aggressive price point. The Core i3-1215U, while a modern 12th-gen chip, is an entry-level processor. By limiting the US market to this configuration, Lenovo directly controls the cost, making the device significantly more affordable than a comparable Surface Pro. This represents a calculated trade-off: users gain the versatile Windows 2-in-1 form factor at a lower price, but sacrifice the raw processing power needed for intensive applications. The fact that it still earns an “Editors’ Choice award for the budget category” despite this limitation suggests that for its intended audience, the performance is considered sufficient for the price.

B. Real-World Productivity

For everyday tasks, the Duet 5i delivers a surprisingly capable experience. The Core i3 CPU provides “decent performance” and is “adequate for everyday apps” such as web browsing, office applications, and email. It is described as “surprisingly snappy” for general use. Users report it handles “web surfing, python scripting (light data science), basic programming (master’s courses)” and “work suite things fine”. This means for the vast majority of users who primarily engage in these activities, the Duet 5i will not feel sluggish.

C. Creative & Light Workload

When it comes to more demanding tasks, the Duet 5i can stretch its capabilities, but with limitations. It is capable of “light video editing at 1080p” and can handle “editing on software like Photoshop Illustrator”. However, for intensive creative work or heavy multitasking, performance might “just barely squeak by”. The 8GB of RAM, while “serviceable for most use cases,” might become a bottleneck with numerous open tabs or complex applications.

D. Gaming & Thermals

If gaming is a priority, the Duet 5i is not the optimal choice. It is “not really doable” for “higher-end games” , and integrated Intel UHD Graphics are simply not designed for modern AAA titles. For instance, running Rise of the Tomb Raider at 1080p with the lowest settings yielded only around 20 FPS, making it “somewhat playable but you’re better off looking elsewhere”. The device does use fans for active cooling – even with the Core i3 – but they operate at a relatively quiet 35 to 40 dBa, generally “quieter than most laptops”.

E. Storage Considerations

One of the most significant compromises in the base model is the “modest” 128GB M.2 PCIe SSD. This capacity “might be tight depending on what you plan to keep on the device”. For users with large photo libraries, extensive software installations, or a collection of media files, this will quickly become a limitation. It is worth noting that some adventurous users have successfully upgraded the SSD , but this is not officially supported and typically voids the warranty.

Actionable Takeaway: Users should set realistic performance expectations. The Duet 5i is a capable machine for daily tasks, web browsing, and light productivity. For demanding creative work or serious gaming, it will reach its limits. Users should be mindful of the 128GB storage; plan to use cloud storage extensively or consider an upgrade if comfortable with the DIY aspect.

The Detachable Experience: Keyboard and Pen

The true magic of a 2-in-1 lies in its ability to seamlessly transition between laptop and tablet modes, and the quality of its input accessories is paramount to this experience.

A. The Included Keyboard

One of the Duet 5i’s most compelling advantages is that its detachable keyboard is included in the price. This stands in stark contrast to Microsoft’s Surface Pro, where the keyboard is a separate, often expensive, accessory. This alone represents significant value for the budget-conscious buyer. The keyboard connects via POGO pins for a secure physical connection but also offers Bluetooth connectivity, allowing it to be detached and still used with the tablet from a distance.

In terms of feel, the keyboard offers a “comfortable typing experience” with “concise while still well spaced apart” keys. It is backlit, a welcome feature for low-light environments. While the plastic keyboard deck might feel “a little cheaper than the Surface keyboard’s,” it is “not as thin” , providing a decent amount of key travel. A minor drawback is the lack of a tilt mechanism for a more ergonomic typing angle, a feature found on some Surface Pro keyboards. The kickstand itself is “sturdy” and offers a “pretty decent range of flexibility” for propping up the tablet at various angles.

The inclusion of the keyboard with the Duet 5i is a strategic move by Lenovo that significantly impacts the total cost of ownership and out-of-the-box value, directly addressing a common pain point for budget-conscious buyers of premium 2-in-1s. The starting price of the Duet 5i is around $750-$790 , while a Surface Pro 8 or 9 starts at $999. When the $139+ cost of a Surface keyboard is factored in , the effective price difference for a functional laptop experience widens considerably. This is a critical value differentiator that directly addresses the “budget” aspect of the query. It allows the Duet 5i to be a complete solution from day one, without hidden costs that often frustrate consumers looking for affordable technology. This strategic bundling by Lenovo positions the Duet 5i as a highly practical and accessible entry point into the Windows 2-in-1 market. It demonstrates an understanding of the budget consumer’s desire for immediate utility and transparent pricing, making it a compelling alternative for those who need a functional hybrid device without the full premium investment.

B. The Digital Pen Experience

The digital pen for the Duet 5i is sold separately , just like with the Surface Pro. The Duet 5i supports a digital pen with 4096 levels of pressure sensitivity and palm rejection , which is standard for modern active pens and allows for nuanced drawing and note-taking. Lenovo’s own Active Pen 3 supports various protocols including AES 2.0 Wacom, MPP 2.0, and WGP , indicating broad compatibility.

However, a mistake often observed is underestimating the importance of a good keyboard and pen for a 2-in-1. While the Duet 5i supports a pen, some user reviews for other Lenovo IdeaPad models (which may share similar pen technology or bundled pens) have criticized the quality of the included or basic digital pens, suggesting they can feel “cheapo” or “wobbly,” making accurate drafts difficult. For a truly premium pen experience, users might need to consider purchasing a higher-end Lenovo Precision Pen 2 or a compatible third-party stylus. This contrasts with Microsoft’s Surface Slim Pen 2, which offers advanced features like haptic feedback for a more natural “pen-on-paper” feel. The pen situation is a more nuanced trade-off: while the Duet 5i supports pens, the quality of the pen experience (e.g., haptic feedback, accuracy, feel) may not match the premium Surface Slim Pen 2, which is a known strength of the Surface ecosystem.

Actionable Takeaway: The included keyboard is a major value proposition, making the Duet 5i a true out-of-the-box 2-in-1. If pen input is critical for a user’s workflow (e.g., digital art, extensive handwritten notes), be prepared to invest in a quality pen beyond the basic bundled options, and always verify compatibility and review user feedback on pen performance.

Battery Life: The Real-World Test

Battery life is often the Achilles’ heel of portable devices, and 2-in-1s are no exception. Manufacturers’ “up to” claims can paint an optimistic picture, but real-world usage often tells a different story.

Lenovo officially claims the IdeaPad Duet 5i tablet can achieve up to 9 hours (MobileMark 2018 benchmark) or up to 11 hours (1080p video playback). In practical evaluations, and consistent with user reports, real-world usage typically yields more conservative figures. Users report “about 7-8 hrs on light normal use with 50% brightness” or “6 to 7 hours with a full charge in typical daily mixed use”. As expected, activities that heavily utilize the CPU, such as video editing, benchmarking, or gaming, will “quickly deplete the battery”.

When comparing to Microsoft’s Surface Pro line, a familiar pattern of optimistic claims emerges. The Surface Pro 9, for instance, boasts “up to 15.5 hours” (Intel model) or “up to 19 hours” (SQ3 model). However, real-world user feedback is often starkly different, with reports of “maybe 5-6 hours” for the Surface Pro 9 and “about 6 continuous hours, not 11” for the Surface Pro 8 , with some users even getting as low as 4 hours. These discrepancies are a “laughably bad” and persistent pain point for Surface users, highlighting a common industry issue with “up to” battery life figures.

The consistent discrepancy between advertised “up to” battery life figures and real-world user experiences across both Lenovo and Microsoft devices points to a systemic industry issue rather than a brand-specific flaw. “Up to” figures are typically derived from highly controlled, low-demand tests, such as video playback with minimal brightness and Wi-Fi. This methodology, while technically accurate to the test, fails to represent “typical device usage” for most consumers. The significant gap between advertised and experienced battery life is a major source of consumer dissatisfaction. For the Duet 5i, its “lower” advertised battery life might actually feel more honest in comparison, and its Core i3’s efficiency helps it maintain decent real-world longevity.

The good news is that the Duet 5i supports Rapid Charge Express, which can bolster battery life by “three extra hours with only 15 minutes of charging”. A full charge typically takes around 2 hours with the included 65W portable power adapter , allowing for quick top-ups during a lunch break or between classes.

Actionable Takeaway: While official claims for both devices should be taken with a grain of salt, the Duet 5i offers decent real-world battery life for its price point, often comparable to or even exceeding the practical usage of some premium Surface Pro models, especially given its lower-power Core i3. The rapid charging feature is a valuable addition for quick power boosts.

Lenovo IdeaPad Duet 5i vs. Surface Pro: The Budget Verdict
