Display Comparison

Both the LG Q9 and G7 ThinQ share a contrast ratio of 2044:1 (nominal) and 3.978 (sunlight), suggesting similar outdoor visibility. However, detailed panel specifications like peak brightness (in nits) and color gamut coverage are missing. Given the G7 ThinQ was positioned as a premium device, it likely benefited from slightly better color calibration and potentially a higher peak brightness, though this is speculative without further data. Both devices likely utilized IPS LCD panels, common for LG at the time.

Camera Comparison

Both devices are listed with 'Photo / Video' capabilities, lacking specific details. However, the G7 ThinQ, as the flagship, likely featured a more advanced camera system with a larger sensor and improved image processing algorithms. While sensor size and aperture data are unavailable, the G7’s positioning suggests superior low-light performance and dynamic range. The Q9’s camera would have been competent, but likely lacked the refinement and features of the G7’s offering. The inclusion of OIS (Optical Image Stabilization) is also more probable on the G7.

Performance

The core difference lies in the chipsets. The LG G7 ThinQ’s Snapdragon 845, built on a 10nm process, is a substantial upgrade over the LG Q9’s Snapdragon 821 (14nm). The 845 features an octa-core CPU (4x2.8 GHz Kryo 385 Gold & 4x1.7 GHz Kryo 385 Silver) compared to the Q9’s quad-core (2x2.15 GHz Kryo & 2x1.6 GHz Kryo). This translates to approximately 25-30% faster CPU performance and a significantly more powerful Adreno 630 GPU in the G7, enabling smoother graphics and higher frame rates in games. The 10nm process also contributes to better thermal efficiency, reducing the likelihood of throttling during sustained workloads.

Battery Life

Interestingly, both the LG Q9 and G7 ThinQ achieve an endurance rating of 77 hours, despite the G7’s more powerful processor. This suggests efficient power management on both devices. Both support 18W wired charging with Quick Charge 3.0, and the G7 ThinQ adds wireless charging (USA only). The G7’s more efficient chipset, despite its higher performance, likely offsets the increased power draw, resulting in comparable real-world battery life. 0-100% charging times would be similar, around 90-120 minutes.

Buying Guide

Buy the LG Q9 if you prioritize affordability and a relatively smooth Android experience for everyday tasks. It’s a good option for users who don’t heavily game or require the absolute fastest performance. Buy the LG G7 ThinQ if you demand a more responsive and future-proof device, especially if you enjoy mobile gaming, photography, or frequently use demanding applications. The Snapdragon 845 offers a tangible performance advantage.

Frequently Asked Questions

❓ Will the LG Q9 struggle with modern, graphically intensive games?
