Overview

When the LG G7 ThinQ launched in mid-2018, it represented LG’s attempt to bridge top-tier hardware with newly branded artificial intelligence features. Built around the Qualcomm Snapdragon 845 platform, a vibrant 6.1-inch QHD+ IPS LCD, and an array of hardware audio enhancements, the G7 ThinQ made a strong statement in the premium flagship space.

Today, the G7 ThinQ occupies a specialized niche. While LG has since exited the mobile phone market, the device maintains a loyal following among audiophiles and budget media enthusiasts who value its 32-bit Hi-Fi Quad DAC, expandable storage, and 3.5mm headphone jack. Evaluating the G7 ThinQ from a long-term ownership perspective reveals a phone that excels as a dedicated digital audio player (DAP) or secondary device, provided you navigate its inherent hardware limitations.

Design and build

LG crafted the G7 ThinQ with a sleek glass-and-aluminum sandwich design. Utilizing Corning Gorilla Glass 5 on both the front and back, wrapped around an anodized aluminum frame, the chassis feels remarkably lightweight at just 162 grams. The 6.1-inch display features a display notch—a trend of its era—surrounded by slim bezels that maintain an impressive screen-to-body ratio.

Physical controls include a dedicated Google Assistant button on the left flank alongside discrete volume keys, while the power button sits on the right. One of the phone's standout acoustic design choices is its "Boombox Speaker" structure, which uses the internal cavity of the chassis as a resonance chamber to produce physical vibration and louder audio when placed on flat surfaces. Tactile feedback remains solid, but long-term glass retention depends heavily on protective casing, as the curved rear glass edges are vulnerable to impact drops.

Everyday performance

The Qualcomm Snapdragon 845 chipset, paired with either 4GB or 6GB of RAM, provided high-end processing speed at launch. For lightweight daily tasks, media streaming, local audio playback, and retro emulation, the performance holds up reasonably well. Navigating system menus and playing local Hi-Res audio files is smooth.

However, software limits are the main bottleneck for long-term daily usability. The G7 ThinQ officially maxed out at Android 10. Without modern security patches or OS updates, banking applications and contemporary heavy apps may lack compatibility or struggle with RAM management. As a offline media device or high-resolution DAP, though, the hardware remains capable and responsive.

Battery, durability, and longevity

Battery capacity has always been the G7 ThinQ's main weak point. LG equipped the phone with a relatively small 3000 mAh Li-Po battery. Even when new, endurance ratings were mediocre; years later, original battery cells frequently suffer from capacity loss, elevated internal resistance, and rapid thermal depletion.

Durability-wise, the chassis holds up well against structural flex thanks to its aluminum midframe. However, time weakens the adhesive gaskets providing IP68 water resistance. Furthermore, thermal interface paste inside the chassis breaks down over years of heat cycles, leading to warmer skin temperatures under sustained CPU loads.

Common issues owners hit

Long-term owners of the G7 ThinQ frequently encounter a few specific hardware fatigue patterns:

• USB-C Port Wear & Moisture Warnings: The bottom charging port is vulnerable to debris accumulation and mechanical wear, often triggering false moisture detection warnings that prevent charging.
• Severe Battery Degradation: Due to the small initial capacity, power cycles stack up quickly, resulting in premature battery failure or unexpected shutdowns.
• Cracked Rear Camera Glass: The raised dual-camera glass cover on the back panel is prone to cracking from minor table impacts.
• Thermal Throttling: Aging thermal compound between the processor and midframe leads to quicker thermal throttling during video playback or charging.

Who it's for

The LG G7 ThinQ is no longer a practical main smartphone for power users who demand multi-day battery life or the latest Android security updates. Instead, it is an absolute gem for:

1. Audiophiles: Those seeking a budget-friendly alternative to expensive dedicated DAPs, capable of driving high-impedance headphones via the built-in Quad DAC.
2. Media Collectors: Users looking for a compact media player with microSD expansion up to 2TB and a sharp, ultra-bright QHD+ screen.
3. Tinkerers: Enthusiasts comfortable replacing aging batteries or installing custom ROMs to extend utility.

Bottom line

The LG G7 ThinQ stands as a testament to LG’s willingness to innovate in mobile hardware. While its small 3000 mAh battery and end-of-life software status limit its role as a primary mobile phone, its unmatched wired audio output, vibrant display, and solid chassis render it a high-value secondary device for audio and media playback.
