Lenovo IdeaPad Slim 3: The Budget Champion

The Lenovo IdeaPad Slim 3 proves you don’t need to spend four figures for a capable laptop. At £599.99, it targets students, remote workers, and anyone needing reliable computing without premium pricing. Read our full Lenovo IdeaPad Slim 3 Review UK 2024 for complete details.

Design and Build Quality

Lenovo hasn’t skimped on aesthetics here. The IdeaPad Slim 3 features a clean, minimalist design with a plastic chassis that feels more premium than its price suggests. It’s available in Arctic Grey, and whilst it won’t turn heads like aluminium unibody designs, it’s perfectly presentable in professional settings.

The 14-inch form factor strikes a sweet spot. It’s large enough for comfortable productivity yet compact enough for daily carrying. At 1.4kg, it’s slightly heavier than ultraportables but still manageable in a backpack. The hinge feels solid, opening smoothly to about 180 degrees.

Display Performance

The 14-inch Full HD (1920×1080) display delivers adequate brightness at around 300 nits. Colours appear reasonably accurate for everyday tasks, though creative professionals will notice the limited colour gamut coverage. The anti-glare coating helps with outdoor visibility, something we appreciated during coffee shop work sessions.

Viewing angles are decent for an IPS panel. Text remains crisp, and the 16:9 aspect ratio provides familiar proportions for Windows applications. It’s not a spectacular display, but it gets the job done without eye strain during extended use.

Performance Capabilities

Our test unit featured an Intel Core i5-1235U processor with 8GB DDR4 RAM. This configuration handles Microsoft Office, web browsing, video conferencing, and light photo editing comfortably. We could maintain 15-20 Chrome tabs without noticeable slowdown, though heavier multitasking occasionally revealed the RAM limitations.

The 256GB SSD provides adequate storage for most users, with boot times around 12 seconds. File transfers averaged respectable speeds, though not matching premium NVMe drives. For students writing essays or professionals managing spreadsheets, performance feels snappy and responsive.

Battery Life Reality

Lenovo claims up to 8 hours, and our testing confirmed this for light workloads. With brightness at 50% and typical productivity tasks, we achieved 7.5 hours consistently. Push it harder with video streaming or multiple applications, and expect closer to 5-6 hours. It’s adequate for a school day or workday with access to charging.

MacBook Air M4: Apple’s AI-Powered Masterpiece

The MacBook Air M4 represents Apple’s vision for the future of personal computing. Starting at £1,025, it integrates the groundbreaking M4 chip with Apple Intelligence features that genuinely enhance productivity. Read our full MacBook Air M4 2025 Comprehensive Review for our complete analysis.

Design Excellence

Apple’s industrial design prowess shines here. The aluminium unibody construction feels incredibly solid, with zero flex in the chassis or keyboard deck. Available in Midnight, Starlight, Space Grey, and Silver, each finish exudes quality. The Midnight variant we tested resists fingerprints better than previous generations.

At just 1.24kg, it’s genuinely portable. The wedge profile has been replaced with a uniform thickness that actually makes it easier to slip into bags. The MagSafe charging port returns, preventing accidental yanks from destroying your laptop. It’s the little details—the satisfying click of the lid closing, the perfectly balanced hinge—that justify the premium pricing.

Display Brilliance

The 13.6-inch Liquid Retina display is spectacular. With 2560×1664 resolution, 500 nits brightness, and P3 wide colour gamut support, it outclasses the IdeaPad Slim in every measurable way. Text appears razor-sharp, colours pop with vibrancy, and the True Tone technology adjusts white balance based on ambient lighting.

What impressed us most was outdoor usability. That 500-nit brightness cuts through glare effectively, making the MacBook Air M4 genuinely usable in bright environments. The slightly taller 16:10 aspect ratio provides extra vertical space for documents and web browsing—a subtle advantage that becomes significant during daily use.

M4 Chip Performance

Here’s where the Lenovo IdeaPad Slim vs MacBook Air M4 comparison becomes lopsided. The M4 chip delivers performance that embarrasses many desktop processors. Our Geekbench 6 scores showed single-core performance around 3,800 and multi-core near 15,000—roughly triple the IdeaPad Slim’s capabilities.

Practical implications? We edited 4K video in Final Cut Pro without dropped frames. Exported a 10-minute 4K project in under 3 minutes. Ran Xcode, Safari with 30 tabs, Messages, Mail, and Spotify simultaneously without thermal throttling. The unified memory architecture means those 16GB feel more like 24GB on traditional systems.

Apple Intelligence Integration

Apple Intelligence transforms how you interact with macOS. Smart writing tools suggest improvements across applications. Image generation creates custom emoji and graphics. Siri finally understands context, handling complex multi-step requests reliably. These aren’t gimmicks—they genuinely save time during daily workflows.

The on-device processing means your data stays private. No cloud uploads for AI features. It’s a significant advantage for professionals handling sensitive information.

Battery Life Supremacy

Apple claims 18 hours, and remarkably, we achieved 16.5 hours during our standard web browsing test. Even with demanding workloads—video editing, photo processing, multiple applications—we consistently got 10-12 hours. The efficiency of Apple Silicon is genuinely remarkable. You can leave the charger at home for full workdays without anxiety.

Head-to-Head: Lenovo IdeaPad Slim vs MacBook Air M4

Performance Showdown

Winner: MacBook Air M4

This isn’t even close. The M4 chip delivers roughly 3x the processing power of the IdeaPad Slim’s Intel Core i5. For everyday tasks like web browsing and document editing, both feel responsive. But push into video editing, photo processing, or running multiple demanding applications, and the MacBook Air M4 maintains composure whilst the IdeaPad Slim struggles.

The unified memory architecture gives the MacBook Air an additional edge. Those 16GB of RAM feel more capable than the IdeaPad’s 8GB DDR4. Memory-intensive applications run smoother, and you can maintain more browser tabs without slowdown.

Display Quality Comparison

Winner: MacBook Air M4

The Liquid Retina display outclasses the IdeaPad Slim’s FHD panel significantly. Higher resolution (2560×1664 vs 1920×1080), better brightness (500 nits vs 300 nits), wider colour gamut (P3 vs sRGB), and superior viewing angles make the MacBook Air M4 the clear winner for anyone who values display quality.

That said, the IdeaPad Slim’s display is perfectly adequate for typical productivity tasks. If you’re not doing colour-critical work or consuming lots of media, you won’t feel shortchanged.

Battery Life Battle

Winner: MacBook Air M4

The MacBook Air M4’s 16+ hour battery life versus the IdeaPad Slim’s 7.5 hours represents a massive advantage. You can genuinely work all day without charging the MacBook Air, whilst the IdeaPad Slim requires midday top-ups during heavy use.

Apple Silicon’s efficiency advantage is undeniable here. The M4 chip sips power during light tasks and manages thermals brilliantly under load, resulting in exceptional endurance.

Build Quality and Design

Winner: MacBook Air M4

The aluminium unibody construction of the MacBook Air M4 feels substantially more premium than the IdeaPad Slim’s plastic chassis. Tighter tolerances, better materials, and superior fit-and-finish justify the price difference for buyers who value build quality.

However, the IdeaPad Slim doesn’t feel cheap. Lenovo has done well creating a presentable design at this price point. It won’t embarrass you in professional settings, even if it won’t impress either.

Keyboard and Trackpad

Winner: MacBook Air M4

Both laptops offer comfortable keyboards suitable for extended typing. The IdeaPad Slim provides decent key travel and satisfying feedback. But the MacBook Air M4’s Magic Keyboard edges ahead with more refined tactility and better backlighting.

The trackpad comparison isn’t even fair. Apple’s Force Touch trackpad remains the industry standard, offering precision and gesture support that Windows trackpads struggle to match. The IdeaPad Slim’s trackpad works fine, but it’s noticeably less responsive and accurate.

Port Selection

Winner: Lenovo IdeaPad Slim 3

Finally, a category where the IdeaPad Slim wins! It offers USB-A ports, HDMI, USB-C, and an SD card reader—practical connectivity for users with existing peripherals. The MacBook Air M4 limits you to two USB-C/Thunderbolt ports plus MagSafe charging, requiring dongles for legacy connections.

For students and professionals with varied connectivity needs, the IdeaPad Slim’s port selection provides genuine convenience.

Value for Money

Winner: Lenovo IdeaPad Slim 3

At £599.99 versus £1,025, the IdeaPad Slim delivers exceptional value. You’re getting capable performance, adequate display quality, and decent battery life for significantly less money. The MacBook Air M4 offers superior performance and features, but whether that justifies the 71% price premium depends on your needs and budget.

For budget-conscious buyers prioritising value, the IdeaPad Slim represents smarter spending. For those who can afford it and value premium performance, the MacBook Air M4 delivers worth matching its price.

Software Ecosystem

Winner: Depends on Your Ecosystem

This comparison defies simple winner declarations. Windows 11 on the IdeaPad Slim offers broader software compatibility, gaming support, and familiarity for most users. macOS on the MacBook Air M4 provides superior security, seamless Apple ecosystem integration, and excellent optimisation.

If you own an iPhone, iPad, or other Apple devices, macOS integration is genuinely magical. Universal Clipboard, Handoff, AirDrop, and iCloud sync create effortless workflows. Windows users with Android phones won’t benefit from these features, making the IdeaPad Slim’s Windows 11 more practical.

Real-World Usage Scenarios

For Students

The Lenovo IdeaPad Slim vs MacBook Air M4 decision for students often comes down to budget. The IdeaPad Slim 3 handles essay writing, research, video streaming, and video calls effortlessly at a price that won’t devastate student loans. Its Windows compatibility ensures access to all required software.

However, students in creative programmes—film, graphic design, music production—should seriously consider the MacBook Air M4. The performance advantage and exceptional battery life justify the investment for demanding coursework. The ability to edit video projects without rendering delays or run design software smoothly pays dividends throughout your degree.

For Remote Workers

Remote workers need reliability, good webcams, and all-day battery life. The MacBook Air M4 excels here with its 16+ hour endurance, allowing you to work from coffee shops or co-working spaces without hunting for outlets. The superior display reduces eye strain during long workdays.

The IdeaPad Slim 3 works adequately for remote work centred on email, documents, and video conferencing. Just keep the charger handy and accept that the webcam quality won’t impress colleagues.

For Creative Professionals

There’s no contest here. The MacBook Air M4’s M4 chip, 16GB unified memory, and brilliant display make it the obvious choice for photographers, videographers, designers, and content creators. The performance advantage translates directly into time saved—faster exports, smoother previews, and no thermal throttling during intensive work.

The IdeaPad Slim 3 struggles with creative workloads. Light photo editing is manageable, but video editing or 3D rendering will frustrate you quickly.

For Casual Users

Casual users browsing the web, streaming Netflix, managing emails, and occasional document editing will find both laptops perfectly adequate. The Lenovo IdeaPad Slim vs MacBook Air M4 choice here depends more on budget and ecosystem preference than performance needs.

The IdeaPad Slim 3 delivers everything casual users need at an accessible price. The MacBook Air M4 offers luxury and future-proofing but represents overkill for basic tasks.

Long-Term Ownership Considerations

Upgradeability

Neither laptop offers user-upgradeable RAM or storage—a disappointing trend in modern laptops. The IdeaPad Slim 3’s 8GB RAM and 256GB storage will feel limiting within 2-3 years as software demands increase. The MacBook Air M4’s 16GB and superior efficiency provide better longevity, but you’re locked into your initial configuration.

Durability and Reliability

Apple’s reputation for build quality and longevity gives the MacBook Air M4 an edge for long-term ownership. The aluminium construction resists wear better than plastic, and macOS typically receives longer software support than Windows laptops.

That said, Lenovo builds reliable machines. With reasonable care, the IdeaPad Slim 3 should provide 4-5 years of service—adequate for its price point.

Resale Value

MacBooks retain value remarkably well. A three-year-old MacBook Air might fetch 50-60% of its original price. Windows laptops depreciate faster, with the IdeaPad Slim 3 likely worth 30-40% after similar time. If you upgrade regularly, this matters.

The Verdict: Our Final Recommendation

The Lenovo IdeaPad Slim vs MacBook Air M4 comparison reveals two excellent laptops serving different audiences. The IdeaPad Slim 3 maximises value, delivering capable performance for everyday tasks without premium pricing. It’s the sensible choice for budget-conscious buyers who need reliable computing without frills.

The MacBook Air M4 justifies its premium with exceptional performance, industry-leading battery life, brilliant display quality, and thoughtful AI integration. It’s the laptop to buy if you can afford it and value long-term performance, reliability, and premium user experience.

Our recommendation? If your budget allows and you value performance, the MacBook Air M4 represents the better long-term investment. Its superior capabilities will remain relevant longer, and the exceptional battery life and display quality enhance daily use significantly. For students, casual users, or anyone prioritising value, the IdeaPad Slim 3 delivers everything you need at a price that makes sense.

The Lenovo IdeaPad Slim vs MacBook Air M4 isn’t about finding the “best” laptop—it’s about finding the right laptop for your specific needs and budget. Both succeed brilliantly at their respective price points.

Final Thoughts on the Lenovo IdeaPad Slim vs MacBook Air M4

After extensive testing, the Lenovo IdeaPad Slim vs MacBook Air M4 comparison reveals clear winners for different use cases.
