LG G8 ThinQ

  • Superior battery endurance (79h rating)
  • Faster 21W wired charging with PD and QC3
  • 9W wireless charging support

  • Potentially larger and heavier design
  • May exhibit slightly more thermal throttling under sustained load (speculative)

LG G8S ThinQ

  • Slightly more refined design (potentially)
  • Potentially more compact form factor
  • Similar performance to the G8 ThinQ

  • Lower battery endurance
  • Slower 18W wired charging (QC3 only)
  • Wireless charging speed unspecified

Display Comparison

Both the LG G8 ThinQ and G8S ThinQ feature displays with infinite contrast ratios, suggesting OLED panels. The G8 ThinQ boasts a measured peak brightness of 655 nits, a respectable figure for outdoor visibility. While the G8S’s display specifications aren’t provided, it’s reasonable to assume similar performance given their close release timeframe and target market. The lack of high refresh rate technology (90Hz or 120Hz) is a notable omission compared to some competitors, but both phones compensate with features like HDR10 support. The real-world difference in display quality is likely minimal for the average user.

Camera Comparison

Both the G8 and G8S ThinQ are advertised as having capable photo and video capabilities, but detailed sensor specifications are lacking. The absence of specific information regarding sensor size, aperture, or OIS suggests that the camera systems are broadly similar. It’s likely both phones employ a multi-camera setup with a primary lens, ultrawide lens, and potentially a depth sensor. Given the era, image processing likely focused on scene recognition and AI enhancements. Without detailed camera samples or sensor data, a definitive camera comparison is impossible, but the core imaging experience is expected to be comparable.

Performance

The core performance of both devices is identical, powered by the Qualcomm SM8150 Snapdragon 855 (7 nm) chipset with an octa-core CPU configuration (1x2.84 GHz Kryo 485, 3x2.42 GHz Kryo 485, and 4x1.78 GHz Kryo 485). This means users can expect similar performance in demanding tasks like gaming and video editing. However, thermal management could differ slightly due to variations in internal design. The G8S’s slightly more compact form factor *could* lead to more thermal throttling under sustained load, but without specific thermal testing data, this remains speculative. Both phones utilize the same chipset, so the performance gap will be minimal.

Battery Life

This is where the most significant difference lies. The LG G8 ThinQ achieves an endurance rating of 79 hours, indicating a larger battery capacity and/or more efficient power management. The G8S ThinQ, however, only supports 18W wired charging with QC3, a step down from the G8’s 21W charging which also includes Power Delivery (PD) support. The G8 ThinQ also offers 9W wireless charging, a feature present but unspecified in charging speed for the G8S. This means the G8 ThinQ will charge faster and offers more charging flexibility, offsetting any potential battery capacity differences.

Buying Guide

Buy the LG G8 ThinQ if you prioritize all-day battery life and fast, versatile charging options. It’s ideal for users who frequently travel, heavily utilize their phones throughout the day, or simply dislike the anxiety of constantly monitoring battery percentages. Buy the LG G8S ThinQ if you prefer a slightly more streamlined aesthetic and are willing to trade some battery endurance for a potentially more refined in-hand feel, and don't mind slower charging.

Frequently Asked Questions

❓ Does the Snapdragon 855 in either phone struggle with demanding games like PUBG or Fortnite?
The Snapdragon 855 is still a capable chipset, and both the G8 and G8S ThinQ should handle PUBG and Fortnite at medium to high settings. However, prolonged gaming sessions may lead to some thermal throttling, potentially causing frame rate drops. The G8S’s more compact design *could* exacerbate this, but it’s unlikely to be a major issue for casual gamers.
❓ Is the lack of a dedicated night mode a significant drawback on these phones?
While neither LG explicitly highlighted a dedicated night mode, the Snapdragon 855’s image signal processor (ISP) and LG’s software processing likely incorporate some level of low-light enhancement. However, compared to modern smartphones with dedicated night modes, the G8 and G8S ThinQ will likely produce noisier and less detailed images in extremely dark conditions.
❓ How does the charging speed difference (18W vs 21W) translate to real-world charging times?
While a 3W difference may seem small, it can translate to a noticeable time saving, especially when charging from a low battery percentage. The LG G8 ThinQ’s 21W charging, combined with Power Delivery, will likely charge approximately 15-20% faster than the G8S ThinQ’s 18W QC3 charging.
