Lenovo Yoga Slim 9i (Gen 10) Review: The Ultimate Premium Ultrabook of 2025?
The Lenovo Yoga Slim 9i Gen 10 (2025 model) is an ultra-premium laptop that blends cutting-edge design with top-tier performance. With Intel’s Lunar Lake processor, a stunning 4K OLED display, and premium build quality, this laptop aims to deliver an elite experience for professionals, creators, and those who appreciate luxury technology. But does it justify its premium price? This in-depth review will explore every detail, from performance and display quality to battery life and usability.


Premium Design & Build Quality
The Lenovo Yoga Slim 9i Gen 10 is a masterpiece of craftsmanship. It continues the Yoga series’ tradition of ultra-thin, lightweight laptops, while adding a sleek Tidal Teal color with a Gorilla Glass finish. This glass-covered chassis exudes sophistication but is also prone to fingerprints and smudges.
- Weight & Portability: Weighing just 1.3kg (2.86 lbs), this laptop is ideal for travelers and professionals. Despite its slim profile, its durability remains solid, thanks to high-quality materials.
- Edge-to-Edge Display: One of the standout design elements is its nearly bezel-less screen, achieved by integrating an under-display webcam. This innovative feature allows for an astonishing 98% screen-to-body ratio.
- Keyboard & Trackpad: The keyboard feels comfortable with well-spaced keys and decent travel distance, but the trackpad is not haptic, which feels like a missed opportunity given its premium nature.
Stunning 4K OLED Display: A Visual Delight
The 14-inch OLED UHD+ (3840×2400) touchscreen is one of the best displays available on any laptop in 2025. Whether you’re a content creator, a professional designer, or an enthusiast for high-quality visuals, this display delivers breathtaking clarity and color accuracy.

- High Refresh Rate & Brightness: The 120Hz refresh rate ensures smooth scrolling and animations, while the 750-nit peak HDR brightness makes HDR content look stunning. 400-500 nits SDR brightness ensures excellent visibility in most lighting conditions.
- Color Accuracy & Contrast: With 100% DCI-P3 coverage, deep blacks, and vibrant colors, this panel is perfect for photo editing, video work, and media consumption.
- Potential Drawbacks: The glossy display is prone to reflections, and PWM flickering at lower brightness levels could be an issue for sensitive users.
Performance: Powered by Intel’s Lunar Lake Processor
At the heart of the Yoga Slim 9i Gen 10 is Intel’s new Ultra 7 258V processor, part of the Lunar Lake lineup. This chipset represents a significant leap in efficiency, performance, and AI acceleration.
Key Specifications:
- Processor: Intel Ultra 7 258V (8 cores, 8 threads, no hyperthreading)
- Graphics: Integrated Intel Arc 140V GPU
- RAM: 32GB LPDDR5X (non-upgradable)
- Storage: 1TB SSD (user-replaceable)
Real-World Performance
- Everyday Tasks: The laptop breezes through web browsing, office applications, and multitasking. Thanks to faster AI-powered optimizations, tasks like video conferencing and smart audio processing work seamlessly.
- Creative Workloads: Adobe Photoshop, Premiere Pro, and DaVinci Resolve run well due to the Intel Arc 140V graphics, which provides a significant boost over older integrated GPUs.
- Gaming: While not a gaming laptop, it handles casual and indie games at 1080p with respectable frame rates.
Battery Life: All-Day Power with Smart Optimizations
One of the major selling points of the 2025 Yoga Slim 9i is its superior battery efficiency, thanks to Intel’s Lunar Lake architecture. Lenovo claims up to 14 hours of battery life, and real-world tests confirm that it holds up remarkably well.
Battery Test Results:
- Modern Office Battery Test: 13-14 hours (40% brightness, balanced mode)
- Web Browsing & Productivity: 10-12 hours
- Video Playback: 11-13 hours
- Heavy Usage (Creative Work, 120Hz on): 7-8 hours
Battery Optimization Tips:
- Switching from 120Hz to 60Hz can extend battery life by 2-3 hours.
- Using Windows power-saving features helps prolong usage during long work sessions.
Ports & Connectivity: Minimalist Yet Functional
Lenovo has opted for a port-minimal design, which might be a dealbreaker for some users. You get:


- 2x Thunderbolt 4 USB-C ports
- 1x USB-C 3.2 Gen 2
- No USB-A, HDMI, or headphone jack (you’ll need dongles/adapters)
While this is fine for users who primarily rely on wireless accessories, those needing a more versatile port selection might be disappointed.
Audio: Surprisingly Good Dolby Atmos Speakers
The Yoga Slim 9i boasts a quad-speaker setup powered by Dolby Atmos. The sound quality is rich, full, and well-balanced, rivaling even the MacBook Pro 14 (M4) in terms of clarity and depth.
- Deep bass, clear vocals, and immersive surround sound.
- Perfect for media consumption and conference calls.
Under-Display Webcam: A Bold Move That Falls Short
Lenovo’s decision to integrate an under-display webcam is an ambitious move. While it helps achieve a near-bezel-less screen, the actual webcam quality is subpar.
- Image quality is blurry and lacks sharpness.
- Not ideal for professional video calls.
- Privacy shutter is built-in, but it’s not a major advantage.
Final Verdict: Is the 2025 Yoga Slim 9i Worth Buying?
