Display Comparison

Both the HTC U11 and Samsung Galaxy S8 boast displays with an 'Infinite' contrast ratio (nominal), achieving 4.768 contrast in sunlight. However, the S8’s curved Super AMOLED panel offers a more visually immersive experience, maximizing screen real estate. While both offer excellent color accuracy, the S8’s display technology is generally considered superior for its vibrant colors and deep blacks. The U11’s display, while good, doesn’t quite match the S8’s visual punch.

Camera Comparison

Both phones feature capable photo and video cameras, but differ in their approach. Detailed sensor sizes and apertures aren't provided, but both capture excellent images in good lighting conditions. The U11 gained recognition for its exceptional low-light performance and video stabilization. The S8’s camera, while excellent, leaned towards more saturated colors, a signature Samsung trait. The lack of detailed sensor information makes a definitive comparison difficult, but the U11’s reputation for video quality gives it a slight advantage.

Performance

The performance battle is nuanced. The Galaxy S8 shipped with either the Exynos 8895 (EMEA) or the Snapdragon 835 (USA & China), while the U11 exclusively used the Snapdragon 835. Both chipsets are built on a 10nm process, offering comparable efficiency. The Exynos 8895, with its custom Mongoose M2 cores, theoretically offered higher peak performance, but was often criticized for thermal throttling under sustained load. The Snapdragon 835 in the U11 generally provided more consistent performance, avoiding the overheating issues sometimes seen in the Exynos variant. Both phones feature octa-core CPUs, but the U11’s Kryo cores are optimized for Qualcomm’s architecture, potentially offering a slight edge in sustained performance.

Battery Life

The Samsung Galaxy S8 holds a clear advantage in battery life, achieving an endurance rating of 84 hours compared to the U11’s 73 hours. This translates to a noticeable difference in real-world usage. The S8 also supports 15W wired charging with QC2 and, crucially, wireless charging (Qi), a feature absent on the U11. While the U11 supports faster 18W wired charging with QC3, the lack of wireless charging limits its convenience. The S8’s larger battery capacity and charging versatility make it the more practical choice for power users.

Buying Guide

Buy the HTC U11 if you prioritize a unique, squeezable design with customizable actions and value strong audio performance. It's ideal for users who enjoy tinkering and want a phone that stands out. Buy the Samsung Galaxy S8 if you prefer a more refined, mainstream experience with a stunning, immersive display, reliable battery life, and the convenience of wireless charging. It’s the better choice for users who prioritize ease of use and a premium aesthetic.

Frequently Asked Questions

❓ Does the Exynos 8895 in the Galaxy S8 overheat during demanding tasks like gaming?
The Exynos 8895 variant of the Galaxy S8 was known to experience thermal throttling under sustained load, particularly during prolonged gaming sessions. This resulted in reduced performance to prevent overheating. The Snapdragon 835 variant, found in US and Chinese models, generally exhibited better thermal management.
❓ How useful are the 'Edge Sense' squeeze sensors on the HTC U11?
The U11’s Edge Sense feature, allowing customizable actions via squeezing the phone’s sides, was genuinely innovative. Users could assign shortcuts to launch apps, take photos, or activate voice assistants. While initially a gimmick for some, many found it to be a convenient and efficient way to interact with their phone.
❓ Is the difference in battery life between the U11 and S8 noticeable in everyday use?
Yes, the 11-hour difference in endurance rating translates to a tangible difference in daily use. Galaxy S8 users could typically expect to get through a full day of moderate to heavy use without needing to recharge, while U11 users might find themselves reaching for a charger sooner.
❓ Does the Samsung Galaxy S8 still receive software updates?
No, Samsung has ended official software support for the Galaxy S8. While it remains functional, it no longer receives security patches or feature updates, making it potentially vulnerable to security threats.
