LG G8S ThinQ

  • Potentially lower price point
  • Snapdragon 855 provides flagship performance
  • OLED display offers vibrant colors

  • Slower 18W charging
  • Less detailed battery endurance information
  • Wireless charging wattage unspecified

LG G8X ThinQ

  • Faster 21W charging with Power Delivery
  • Slightly better battery endurance (111h rating)
  • Brighter display (603 nits)

  • Higher price compared to the G8S
  • Still uses the Snapdragon 855 (older chipset)
  • Camera specs lack detail

Display Comparison

Both the LG G8S and G8X feature OLED displays, but the G8X boasts a significantly brighter panel, reaching a measured 603 nits. While both offer an 'infinite' contrast ratio (typical for OLED), the higher peak brightness of the G8X translates to better visibility in direct sunlight. Details regarding refresh rate and resolution are missing, but given the era, both likely feature a 60Hz, FHD+ panel. The G8X’s brighter display is a clear advantage for outdoor use.

Camera Comparison

Both the G8S and G8X are listed as having 'Photo / Video' capabilities, lacking specific details. Without sensor size or aperture information, a direct comparison is difficult. However, LG’s image processing was generally well-regarded during this period. The absence of details suggests a similar camera experience, with the G8X potentially benefiting from slightly better image stabilization due to its overall more refined feature set. The lack of detail makes it difficult to assess any meaningful difference in camera performance.

Performance

Both devices are equipped with the Qualcomm Snapdragon 855 (7nm) chipset, featuring an octa-core CPU configuration identical in clock speeds: 1x2.84 GHz Kryo 485, 3x2.42 GHz Kryo 485, and 4x1.78 GHz Kryo 485. This means raw processing power will be virtually indistinguishable between the two. However, the G8X’s slightly better battery endurance suggests potentially more sustained performance under load, minimizing thermal throttling. RAM specifications are not provided, but both likely feature 6GB or 8GB of LPDDR4X RAM, sufficient for smooth multitasking.

Battery Life

The LG G8X ThinQ edges out the G8S in battery performance, achieving an endurance rating of 111 hours versus an unspecified rating for the G8S. Crucially, the G8X supports 21W wired charging with Power Delivery (PD) and Quick Charge 3.0 (QC3), significantly faster than the G8S’s 18W QC3 charging. The G8X also offers 9W wireless charging, while the G8S’s wireless charging capabilities are simply listed as ‘Wireless’ without specifying wattage. This faster charging and PD support on the G8X translate to a more convenient user experience, allowing for quicker top-ups.

Buying Guide

Buy the LG G8S ThinQ if you prioritize finding the lowest possible price for a Snapdragon 855-powered phone and are comfortable with slower charging speeds. Buy the LG G8X ThinQ if you value faster charging, slightly better battery life, and are willing to pay a premium for the convenience of Power Delivery support. Both phones are excellent choices for users who want a flagship experience without the flagship price tag of newer models.

Frequently Asked Questions

❓ Does the Snapdragon 855 in either phone struggle with demanding games like PUBG Mobile?
The Snapdragon 855 is still a capable chipset, but it's not the latest. While both phones can run PUBG Mobile, you might experience some frame drops during intense battles, especially on higher graphics settings. Thermal throttling could also become a factor during extended gaming sessions, potentially impacting performance more on the G8S due to its less efficient charging and potentially less optimized thermal design.
❓ Is the lack of detailed camera specifications a significant drawback?
The absence of sensor size and aperture information makes it difficult to assess the camera's low-light performance and overall image quality. However, LG's image processing was generally good during this era, so both phones should produce acceptable results in most lighting conditions. Don't expect flagship-level camera performance comparable to newer devices.
❓ How long does it realistically take to charge the LG G8X from 0% to 100%?
With its 21W charging and Power Delivery support, the LG G8X should fully charge from 0% to 100% in approximately 1 hour and 45 minutes to 2 hours, depending on the charger and ambient temperature. This is significantly faster than the LG G8S, which will likely take over 2.5 hours with its 18W charger.
