Galaxy S8 Vs Lg V20 Buying Guide

Camera Capabilities

The Galaxy S8 boasts a single, stellar 12MP rear camera with an f/1.7 aperture, excelling in low-light performance and offering impressive detail and color reproduction. Its Dual Pixel autofocus ensures rapid and accurate focusing. The LG V20, on the other hand, features a dual-camera system: a 16MP main sensor and an 8MP wide-angle lens.

Display and Design

Samsung’s Galaxy S8 redefined smartphone displays with its immersive 5.8-inch Super AMOLED Infinity Display, featuring minimal bezels and a stunning 18.5:9 aspect ratio. This creates a truly edge-to-edge viewing experience, perfect for media consumption. The LG V20 sports a more traditional 5.7-inch IPS LCD display with a 16:9 aspect ratio. While still a good display, it lacks the visual flair and immersion of the S8’s panel. The V20’s design prioritizes durability with its MIL-STD-810G certification.

Performance and Battery Life

Under the hood, the Galaxy S8 is powered by either the Snapdragon 835 or Exynos 8895 chipset, paired with 4GB of RAM, delivering fluid performance for everyday tasks and demanding applications. Its 3000mAh battery, while not the largest, is optimized for efficiency. The LG V20 features the Snapdragon 820 processor and 4GB of RAM, offering solid performance, though it’s a generation older than the S8’s chip. The V20’s key advantage lies in its user-replaceable 2980mAh battery, offering a significant convenience for power users.

Audio and Extra Features

The LG V20 shines in its audio capabilities, featuring a Quad DAC (Digital-to-Analog Converter) for superior sound quality through headphones, making it a audiophile’s dream. It also includes a 3.5mm headphone jack and a powerful built-in speaker. The Galaxy S8, while having decent audio output, doesn’t compete with the V20’s audiophile-grade experience. Both phones offer water resistance (IP68 for S8, splash resistance for V20), but the V20’s removable battery and IR blaster are unique selling points. (See Also: Nikon 50 1 8 Vs 1 4 )

Frequently Asked Questions

Which phone has a better camera for low-light photography?

The Samsung Galaxy S8 generally takes superior photos in low-light conditions. Its 12MP rear camera, with its wider f/1.7 aperture and advanced Dual Pixel autofocus, captures more light and detail, resulting in brighter and less noisy images compared to the LG V20. While the V20’s dual-camera setup offers versatility, the S8’s single sensor is more optimized for challenging lighting environments.

Is the LG V20’s removable battery a significant advantage?

For users who frequently find themselves away from a charger or who prefer not to wait for a phone to recharge, the LG V20’s removable battery is a major advantage. It allows for instant power by swapping in a fresh, fully charged battery. This feature is absent on the Galaxy S8, which relies on its internal, non-user-replaceable battery, making battery swaps impossible.

Which phone offers a more immersive viewing experience?

The Samsung Galaxy S8 provides a significantly more immersive viewing experience thanks to its “Infinity Display.” This design features a high screen-to-body ratio with minimal bezels and an elongated 18.5:9 aspect ratio. This makes videos, games, and general browsing feel more expansive. The LG V20’s display, while good, has a more traditional aspect ratio and noticeable bezels, making it less visually engaging.

How do the audio outputs compare?

The LG V20 is the clear winner for audio enthusiasts. It features a Quad DAC, delivering significantly higher fidelity audio through headphones than the Galaxy S8. This results in richer, more detailed sound reproduction. While the S8’s audio is perfectly adequate for most users, the V20’s audio prowess is a standout feature for those who prioritize exceptional sound quality from their mobile device.

Which phone is better for gaming?

For raw gaming performance, the Galaxy S8 holds a slight edge. Its Snapdragon 835/Exynos 8895 chipset is more powerful and efficient than the LG V20’s Snapdragon 820. This translates to smoother frame rates and better handling of graphically intensive games. However, both phones are capable of running most mobile games well, and the V20’s expansive display can still offer an enjoyable gaming experience.

Final Verdict

The Samsung Galaxy S8 stands out with its revolutionary Infinity Display, superior camera performance, and more powerful processor, offering a premium user experience. While the LG V20 impresses with its audiophile-grade sound and the convenience of a removable battery, the S8’s overall package, from design to daily performance, makes it the more compelling device for most users seeking a flagship experience in 2017.
