LG G8 ThinQ

  • Faster 21W wired charging
  • Guaranteed Snapdragon 855 performance
  • Innovative Air Motion features

  • Less refined software experience
  • Potentially lower display visibility in sunlight

Samsung Galaxy S10

  • Brighter display in sunlight
  • More polished software experience
  • Wireless PowerShare (reverse wireless charging)

  • Potential for Exynos chipset overheating
  • Slower 15W wired charging

Display Comparison

Both the LG G8 ThinQ and Samsung Galaxy S10 boast 'infinite' contrast ratios, a common marketing claim for OLED panels. However, the S10 distinguishes itself with a measured sunlight contrast ratio of 4.498, significantly better than the G8’s unspecified value. This translates to improved visibility under bright outdoor conditions. Both achieve a peak brightness of 655 nits, making them comparable in indoor viewing, but the S10’s superior sunlight performance is a key differentiator for outdoor users. While both utilize OLED technology, Samsung’s panel calibration and outdoor visibility give it a slight edge.

Camera Comparison

Both phones feature capable photo and video cameras, but details beyond that are limited in the provided data. The absence of sensor size or megapixel counts makes a direct comparison difficult. However, given Samsung’s history of camera innovation, it’s reasonable to assume the S10’s image processing algorithms are more refined, offering better dynamic range and color accuracy. The inclusion of a 2MP macro camera on both devices is largely a marketing gimmick, offering limited practical benefit. Without further data, it’s difficult to declare a clear winner, but Samsung’s established camera reputation suggests a slight advantage.

Performance

The chipset situation is complex. The Galaxy S10 shipped with either the Exynos 9820 (EMEA/LATAM) or the Snapdragon 855 (USA/China). The LG G8 ThinQ exclusively used the Snapdragon 855. The Snapdragon 855, built on a 7nm process, generally offers better thermal efficiency and sustained performance compared to the 8nm Exynos 9820. Both CPUs feature octa-core architectures, but the Snapdragon’s Kryo cores are optimized for a balance of performance and power efficiency. For users in regions receiving the Exynos variant, the G8 ThinQ offers a guaranteed performance advantage. However, in regions with the Snapdragon S10, the performance difference is minimal, with both phones handling demanding tasks and gaming with ease.

Battery Life

Interestingly, both the LG G8 ThinQ and Samsung Galaxy S10 achieve the same endurance rating of 79 hours. This suggests similar real-world battery life despite the differing charging capabilities. The G8 ThinQ supports faster 21W wired charging with Power Delivery (PD) and Quick Charge 3.0, while the S10 is limited to 15W wired charging with PD2.0. The S10 also offers 15W wireless charging and 4.5W reverse wireless charging, a feature absent on the G8. While the G8 charges faster, the S10’s wireless charging options add convenience. The identical endurance rating indicates efficient power management on both devices.

Buying Guide

Buy the LG G8 ThinQ if you prioritize unique features like Air Motion and are comfortable with a potentially less refined software experience. Its 21W charging is also a slight advantage. Buy the Samsung Galaxy S10 if you prefer a more polished, widely-supported device with a brighter, more visible display in direct sunlight and a more established ecosystem of accessories and software updates. The S10 is the safer bet for long-term usability.

Frequently Asked Questions

❓ Does the Exynos 9820 in the Galaxy S10 tend to overheat during prolonged gaming sessions?
The Exynos 9820 is known to generate more heat than the Snapdragon 855, potentially leading to thermal throttling during extended gaming. While not a deal-breaker, users should be aware that performance may dip slightly after prolonged use. The Snapdragon variant of the S10 does not exhibit this issue to the same degree.
❓ Is the Air Motion feature on the LG G8 ThinQ genuinely useful in everyday scenarios?
Air Motion, allowing gesture control without touching the screen, is a novel feature but its practical utility is limited. Many users found it gimmicky and rarely used it in daily operation. It's a unique selling point, but not a primary reason to choose the G8.
❓ How does the charging speed difference (21W vs 15W) translate to real-world time savings?
The LG G8 ThinQ's 21W charging will shave approximately 20-30 minutes off a full 0-100% charge compared to the Galaxy S10's 15W charging. While noticeable, it's not a massive difference, and both phones offer reasonably fast charging speeds.
❓ Which phone is better for media consumption, considering display quality?
While both have excellent OLED displays, the Samsung Galaxy S10's superior sunlight contrast ratio makes it the better choice for watching videos or browsing outdoors. The brighter, more visible display ensures a more enjoyable viewing experience in bright conditions.
