ASUS Vivobook S14 OLED 2025 (S5406S) Review: The Ultimate Everyday Laptop?

Introduction

The laptop market in 2025 is more competitive than ever, with manufacturers pushing the boundaries of what's possible in thin and light designs. ASUS has long been at the forefront of innovation, and their latest Vivobook S14 OLED aims to set a new standard for everyday computing. But does it deliver on its promises? Let's dive deep into what makes this laptop tick and find out if it's worthy of your hard-earned money.

Design and Build Quality: Sleek, Sustainable, and Sturdy

Eco-Friendly Materials Take Center Stage

ASUS has made significant strides in sustainability with the 2025 Vivobook S14 OLED. The laptop chassis is now constructed from a unique blend of recycled aluminum and bio-based plastics, reducing its carbon footprint without compromising on durability or aesthetics.

The "Cosmic Blue" color option we tested is a refreshing departure from the sea of silver laptops. Its subtle shimmer catches the light beautifully, while a nano-ceramic coating provides excellent fingerprint resistance.

Impressively Thin and Light

Dimensions: 12.3 x 8.7 x 0.59 inches (313 x 220 x 15 mm)
Weight: 2.65 lbs (1.2 kg)

The Vivobook S14 is a featherweight champion, shaving off even more bulk compared to its predecessors. It's noticeably more portable than many 14-inch competitors, making it a dream for frequent travelers or students constantly on the move.

Build Quality That Inspires Confidence

Despite its svelte profile, the Vivobook S14 feels remarkably solid. There's minimal flex in the keyboard deck, and the hinge mechanism is smooth yet sturdy. ASUS claims military-grade durability (MIL-STD-810H), and our testing suggests this isn't just marketing speak – this laptop can handle the rigors of daily use with ease.

Display: OLED Excellence Evolves

Specs at a Glance

14-inch 2.8K (2880 x 1800) OLED
16:10 aspect ratio
90Hz refresh rate
600 nits peak brightness (HDR)
100% DCI-P3 color gamut
VESA DisplayHDR 600 True Black certified

A Visual Feast

ASUS continues to lead the charge in bringing OLED technology to mainstream laptops, and the Vivobook S14's display is nothing short of spectacular. The 2.8K resolution provides razor-sharp text and images, while the 16:10 aspect ratio offers extra vertical real estate that's great for productivity.

Colors are vibrant without being oversaturated, and the perfect blacks that OLED is known for make everything from movies to web browsing a joy. The 90Hz refresh rate is a noticeable upgrade from 60Hz panels, providing smoother scrolling and improved responsiveness in everyday tasks.

Brightness and Outdoor Usability

With 600 nits of peak brightness in HDR content, this display gets plenty bright for most scenarios. However, it's worth noting that typical brightness in SDR content hovers around 400 nits. This is still good for indoor use, but you might struggle a bit with glare in very bright outdoor environments.

Eye Care and Longevity

ASUS hasn't forgotten about eye comfort. The display is TÜV Rheinland certified for low blue light emissions, and there's a built-in ambient light sensor for automatic brightness adjustment.

To address potential OLED burn-in concerns, ASUS has implemented several software features, including pixel shifting and a screen saver that activates during periods of inactivity. While long-term durability remains to be seen, these measures should help preserve image quality over the laptop's lifespan.

Performance: Balancing Power and Efficiency

Key Specs

Intel Core Ultra 7 155H processor (6 P-cores, 8 E-cores, 2 LP E-cores)
Intel Arc Graphics (integrated)
32GB LPDDR5x RAM
1TB PCIe 4.0 NVMe SSD

Everyday Computing: Smooth Sailing

For typical productivity tasks – web browsing, document editing, video calls, and light photo editing – the Vivobook S14 OLED absolutely flies. The combination of the efficient Intel Core Ultra processor and fast LPDDR5x RAM means you can comfortably juggle multiple applications without slowdowns.

Content Creation: Surprisingly Capable

While not marketed as a dedicated creator's machine, the Vivobook S14 holds its own in less demanding creative workloads. Video editing in 1080p is smooth in programs like DaVinci Resolve, and the color-accurate display is a boon for photo editing. However, for heavy 4K video work or complex 3D rendering, you'll still want a laptop with a dedicated GPU.

Gaming: Casual-Friendly

The integrated Intel Arc graphics represent a significant leap over previous generations. You can comfortably play many popular esports titles at 1080p with medium to high settings. We tested League of Legends and achieved a consistent 100+ fps at 1080p high settings. More demanding AAA games will require lowered settings and resolutions, but the fact that they're playable at all on an ultraportable is impressive.

Thermals and Noise

ASUS has implemented an improved cooling system they call "IceBlade 2.0." In our testing, the laptop remained comfortably cool during most tasks, with fan noise being barely noticeable. Under sustained heavy loads (like gaming or video rendering), the fans do become audible, but not annoyingly so. Surface temperatures stayed reasonable, with only the area above the keyboard getting warm to the touch.

Battery Life and Charging: All-Day Endurance

Battery Specs

75Wh lithium-polymer battery
65W USB-C Power Delivery charger (included)

Real-World Battery Life

ASUS claims up to 13 hours of battery life, but as always, real-world usage varies. In our testing, with mixed productivity work at 50% brightness and Wi-Fi on, we consistently achieved 10-11 hours of use. This is excellent for a laptop with an OLED display and should comfortably get most users through a full workday.

Charging Speed

The included 65W charger can bring the battery from 0 to 60% in about 45 minutes, with a full charge taking around 1 hour and 45 minutes. The laptop also supports USB-C Power Delivery, so you can top up using portable power banks or other compatible chargers.

Keyboard, Trackpad, and Ports: Productivity Essentials

Keyboard: Comfortable and Feature-Packed

The backlit keyboard offers a pleasant typing experience with good key travel (1.4mm) and tactile feedback. The layout is spacious and includes a full-sized number row and inverted-T arrow keys. A nice touch is the textured power button that doubles as a fingerprint sensor for quick logins.

ASUS has included some thoughtful extras:

An "Emoji" key for quick access to symbols and emojis
A dedicated key to launch the MyASUS app
Function keys that control various system settings

Trackpad: Spacious and Precise

The glass-covered trackpad is generously sized and supports all Windows Precision drivers multi-touch gestures. Palm rejection works well, and the click mechanism has a satisfying feel. A standout feature is the embedded NFC sensor in the top-right corner of the trackpad, allowing for quick pairing with compatible devices.

Ports: Plenty of Options

For a thin laptop, the port selection is impressive:

2x Thunderbolt 4 (USB-C)
1x USB 3.2 Gen 2 Type-A
1x USB 2.0 Type-A
HDMI 2.1
3.5mm audio jack
MicroSD card reader

The inclusion of HDMI 2.1 is particularly noteworthy, allowing you to drive high-refresh rate external displays.

Software and Special Features: Beyond the Basics

Windows 11 Pro: Productivity-Focused

The Vivobook S14 OLED comes with Windows 11 Pro pre-installed, offering additional security and management features compared to the Home edition.

MyASUS App: Central Control Hub

The MyASUS app serves as a one-stop shop for system settings, diagnostics, and ASUS-specific features. Some standout capabilities include:

AI noise-cancellation for video calls
Battery health settings to extend long-term lifespan
Display color profile customization
Fan profile adjustments

ASUS Pen 2.0 Support

While not included, the laptop supports the ASUS Pen 2.0 with 4,096 levels of pressure sensitivity. This can be useful for note-taking or light sketching, even though the display itself isn't touch-enabled.

Wi-Fi 6E and Bluetooth 5.2

The latest wireless standards ensure fast, stable connections and seamless pairing with peripherals.

Value Proposition and Target Audience

At a starting price of $1,299 (our reviewed configuration costs $1,499), the ASUS Vivobook S14 OLED positions itself in the upper mid-range of the ultraportable market. It's not the cheapest option, but it offers a compelling mix of premium features that justify the price for the right user.
