LG G8S ThinQ

  • Potentially better value due to lower price.
  • Likely similar performance to the G8 due to the same chipset.
  • May offer slightly improved power efficiency.

  • Slower 18W charging compared to the G8’s 21W.
  • Wireless charging wattage not specified.

LG G8 ThinQ

  • Faster 21W wired charging with PD and QC3.
  • Higher peak display brightness (655 nits).
  • Infinite contrast ratio on the display.

  • Generally more expensive than the G8S.
  • Battery endurance is the same as the G8S despite faster charging.

Display Comparison

Both the LG G8 and G8S feature similar display technology, though specific panel details beyond the G8’s measured 655 nits peak brightness aren’t provided. The G8 boasts an infinite contrast ratio, suggesting a high-quality OLED panel. Without further data on color accuracy or refresh rate, the G8’s higher peak brightness is the only quantifiable difference, potentially offering better visibility in direct sunlight. The lack of LTPO technology in either model means variable refresh rates aren’t present, impacting power efficiency compared to newer displays.

Camera Comparison

Both the G8 and G8S are advertised as having capable photo and video capabilities, but detailed sensor information is absent. Without knowing sensor sizes, apertures, or image processing algorithms, a direct comparison is impossible. The presence of a 'Photo / Video' designation suggests similar feature sets, but the G8S’s potential for slightly better power efficiency could translate to more consistent camera performance during extended use. The lack of detail regarding the 2MP macro camera on either device suggests it’s a secondary feature unlikely to be a deciding factor.

Performance

Both devices are equipped with the Qualcomm SM8150 Snapdragon 855 (7 nm) chipset, featuring an octa-core CPU configuration identical in clock speeds. This means raw processing power will be virtually indistinguishable between the two. The performance will be limited by thermal throttling, and without specific thermal design details, it’s difficult to predict which phone manages heat better. However, the G8S’s slightly later release may indicate minor optimizations in power management. RAM specifications are not provided, but both likely utilize LPDDR4X, common for 2019 flagships.

Battery Life

The LG G8 ThinQ boasts an endurance rating of 79 hours, indicating solid battery life. However, the G8S’s battery capacity is not specified. The G8 supports 21W wired charging with Power Delivery (PD) and Quick Charge 3 (QC3), while the G8S is limited to 18W with QC3. This means the G8 can charge significantly faster, potentially reaching 50% charge in less time. The G8 also supports 9W wireless charging, while the G8S’s wireless charging capabilities are simply listed as ‘Wireless’ without a specified wattage. The G8’s faster charging is a clear advantage for users who frequently need to quickly replenish their battery.

Buying Guide

Buy the LG G8S ThinQ if you prioritize value and all-day battery life without sacrificing performance. It’s ideal for users who frequently use their phones for media consumption, social media, and everyday tasks. Buy the LG G8 ThinQ if you absolutely need the fastest possible charging speeds and are willing to pay a premium for it. This phone is best suited for power users who frequently find themselves needing to top up their battery quickly.

Frequently Asked Questions

❓ Does the Snapdragon 855 in either phone exhibit significant thermal throttling during prolonged gaming sessions?
While the Snapdragon 855 is a powerful chipset, it is known to throttle under sustained load. Without specific thermal testing data for the G8 and G8S, it’s difficult to say which handles heat better. However, the G8S’s slightly later release may indicate minor software optimizations for thermal management, but don't expect a dramatic difference.
❓ Is the 9W wireless charging on the LG G8 ThinQ a substantial improvement over the G8S’s unspecified wireless charging?
Yes, 9W wireless charging is noticeably faster than the typical 5W wireless charging found on many older devices. The G8S’s lack of a specified wattage suggests it may be slower, making the G8 a better choice for users who frequently rely on wireless charging.
❓ Given the similar battery endurance ratings, does the faster charging of the G8 ThinQ negate the need for a larger battery?
For many users, yes. The G8 ThinQ’s 21W charging allows for quick top-ups, meaning you can easily add several hours of usage in a short amount of time. This can be more convenient than a larger battery that takes longer to charge, especially if you have access to a charger throughout the day.
