Dell Inspiron 3520 Laptop Review: Performance, Battery, and Display Tested

If you're looking for a reliable thin and light laptop that balances performance, portability, and daily productivity, the Dell Inspiron 3520 is one model that deserves attention. Priced around ₹48,511, it offers a balanced package of modern Intel 12th-Gen power, solid build quality, and an experience designed to handle both professional and personal workloads with ease.

Whether you’re a student attending online classes, a professional working remotely, or someone who needs a dependable laptop for multitasking, the Inspiron 3520 promises consistent performance without stretching your budget. Dell’s long-standing reputation for durability and after-sales service adds further confidence - especially in a market where many budget laptops cut corners on build and thermal design.

But how does it hold up in everyday use - from typing reports and streaming content to handling multitasking and casual gaming? Let’s take a closer look.

Design and Build Quality

At first glance, the Dell Inspiron 3520 embodies Dell’s trademark minimalism. The platinum silver finish gives it a clean, professional aesthetic that fits seamlessly in an office environment or a study setup. Its design feels understated yet purposeful - not flashy, but polished enough to look premium for the price.

Weighing 1.65 kg, it strikes a comfortable middle ground between portability and sturdiness. You can easily slip it into a backpack and carry it to work, college, or travel, without feeling weighed down. The matte texture also helps resist fingerprints, keeping the device looking neat even after long use.

The laptop’s three-side narrow bezels around the display enhance visual immersion and give the screen more presence without increasing overall dimensions. The hinge feels solid, offering smooth resistance when opening and closing - a small but often overlooked indicator of Dell’s build quality.

A notable touch is Dell’s ComfortView software, which helps reduce blue light emissions. For users who spend hours working on documents, spreadsheets, or browsing, this feature noticeably reduces eye strain during long sessions. Combined with its anti-glare display finish, it’s clearly designed for productivity-first users.

The keyboard deck has minimal flex, and the spacious palm rest provides decent support during extended typing sessions. While it’s primarily plastic, the overall construction feels robust and well-balanced - more durable than many laptops in this price bracket.

In short, Dell has struck a smart balance here: a design that’s simple, professional, and comfortable to use every day - without unnecessary frills.

Ports available:

• 2 × USB 3.2 Gen 1
• 1 × USB 2.0
• 1 × HDMI 1.4 (supports up to 1080p @ 60 Hz)
• 1 × Headset jack
• 1 × SD card reader
• 1 × Power jack

The overall build feels sturdy for its price. Though made of plastic, it manages to give a premium everyday experience for a budget-friendly laptop.

Now let’s see if the display matches the refined design.

Dell Inspiron 3520 Display Quality

The Dell Inspiron 3520 features a 15.6-inch Full HD (1920×1080) WVA anti-glare display with a 120 Hz refresh rate and 250 nits brightness. On paper, these numbers may look standard, but in practice, this screen offers a surprisingly balanced experience for both work and leisure.

While 250 nits isn’t bright enough for outdoor use under direct sunlight, it performs perfectly indoors - whether you’re writing, editing documents, or streaming. The matte anti-glare finish helps cut reflections in bright rooms, and text clarity remains sharp thanks to Dell’s solid panel calibration.

The 120 Hz refresh rate is a game changer in this price range. Scrolling through long web pages, navigating spreadsheets, or watching fast-paced videos feels buttery smooth. Even simple animations in Windows 11 appear more fluid, which makes the overall experience feel snappier.

Color reproduction is decent for day-to-day use - sufficient for basic photo editing, design projects, or PowerPoint presentations. However, users involved in color-critical creative work might find it lacking in deep color accuracy compared to IPS panels in higher-end ultrabooks. For casual creators and students, though, it’s more than capable.

In short, Dell has balanced performance and practicality here: a smooth, flicker-free display that’s easy on the eyes and responsive for everyday productivity.

At the heart of the Inspiron 3520 lies Intel’s 12th Gen Core i5-1235U processor, which combines 10 cores (2 Performance + 8 Efficient) and 12 threads, boosting up to 4.4 GHz. This configuration is designed to deliver a strong balance between power and energy efficiency - perfect for users who demand speed without excessive heat or noise.

Paired with 8 GB DDR4 RAM and a 512 GB SSD, the laptop performs admirably in most real-world scenarios. Apps open swiftly, multitasking feels seamless, and system responsiveness remains snappy even with multiple browser tabs or background updates running. For most students, office users, and light editors, this is more than enough.

🧠 Benchmark Insights and Real-World Performance

• Boot times are nearly instant - you can go from power-on to desktop in under 10 seconds.
• Handles multitasking smoothly across Chrome, Office 365, video playback, and note-taking apps.
• Intel Iris Xe graphics allow light gaming and media editing - titles like Valorant, Rocket League, and CS:GO run well at medium settings.
• Thermal management is solid; fans stay quiet during normal use and only get mildly audible under sustained CPU load.
• Productivity tools like Excel, Photoshop, and Canva benefit from the processor’s burst performance.

If you plan to keep this laptop for several years, upgrading to 16 GB RAM is highly recommended. It not only boosts multitasking but also ensures smoother performance with future Windows updates and heavier workloads.

Overall, Dell’s tuning makes the Inspiron 3520 feel quick, efficient, and reliable - exactly what most mid-range users expect from an everyday machine.

Battery Life and Charging

Battery life is a pleasant surprise on the Inspiron 3520. Thanks to Dell’s ExpressCharge technology, the battery can reach 80% in just about an hour when using the official 65 W adapter - a major advantage for people on the go.

In daily mixed use — including web browsing, document editing, and video playback — you can expect 5 to 6 hours of runtime, depending on screen brightness and workload. For a laptop of this size and power, that’s a respectable figure.

The 65 W adapter recharges the battery quickly and safely. It’s best to stick with Dell’s recommended charger, as smaller-capacity adapters charge slower and may affect long-term battery health.

The power efficiency of Intel’s 12th Gen chips, combined with Dell’s software optimization, keeps thermals under control and extends unplugged productivity time - perfect for office meetings, classroom use, or light travel days.

In essence, while it’s not an “all-day battery” laptop, the Inspiron 3520 manages to deliver reliable unplugged performance and rapid recharge support, making it practical for real-world users.

Keyboard, Trackpad, and Audio

Typing on the backlit keyboard feels satisfying, with a comfortable layout and decent key travel that suits long typing sessions or late-night work. The keys have a quiet, tactile response, and the slightly curved surface adds to typing accuracy. The spacious touchpad supports multi-finger Windows gestures smoothly, making scrolling and app switching effortless.

The dual stereo speakers produce clear vocals and crisp mids, suitable for calls, meetings, and streaming. However, bass remains limited - a common trade-off in thin laptops. Using a good pair of headphones through the reliable 3.5 mm audio jack significantly enhances clarity and immersion.

Connectivity and Features

The Dell Inspiron 3520 includes Wi-Fi 6 and Bluetooth 5.2, ensuring faster wireless speeds and stronger connections, even in crowded environments like cafés or coworking spaces. These upgrades make a noticeable difference for video calls and large file transfers.

Out of the box, it comes pre-loaded with:

• Windows 11 Home (lifetime license)
• Microsoft Office Home & Student 2021
• McAfee Multi-Device Security (15-month subscription)

Together, these make the laptop ready for productivity from day one - no need to buy or install extra essentials.

Verdict – Is the Dell Inspiron 3520 Worth Buying?

The Dell Inspiron 3520 positions itself as a dependable everyday laptop that delivers more than its price suggests.

Features like Wi-Fi 6, Bluetooth 5.2, and ExpressCharge support add modern convenience and make it a solid fit for hybrid or on-the-go professionals.

If your priority is smooth everyday performance, fast boot times, and strong brand reliability, the Inspiron 3520 makes a compelling case under ₹50,000.
