Overview

When the LG V40 ThinQ launched in late 2018, it represented the absolute pinnacle of LG's hardware ambition. Featuring a pioneer five-camera setup (three rear, two front), a bright 6.4-inch Quad HD+ P-OLED display, and the iconic 32-bit ESS Sabre Hi-Fi Quad DAC, the V40 was built specifically for power users and audio enthusiasts.

Years later, LG has exited the smartphone business, but the V40 ThinQ retains a dedicated following. It occupies a specialized niche: an affordable alternative to dedicated high-resolution Digital Audio Players (DAPs) and a solid secondary offline media phone. Equipped with a Snapdragon 845 chip and 6GB of RAM, its processing hardware holds up reasonably well for audio playback, video streaming, and local storage management, though the realities of an aging battery and outdated software require a pragmatic approach to ownership.

Design and build

LG nailed the ergonomics on the V40 ThinQ. Despite housing a large 6.4-inch panel, the device weighs just 169 grams and measures 7.7mm thin. The frame is constructed from sturdy aluminum, sandwiched between Gorilla Glass 5 on the front and a silky, silky-matte glass back that resists fingerprint smudges remarkably well.

The tactile layout is traditional and user-friendly. A rear-mounted capacitive fingerprint scanner rests naturally where your index finger sits, providing snappy unlocks. LG also retained the 3.5mm headphone jack along the bottom edge, positioned right next to the USB-C port and bottom-firing speaker. The device carries an IP68 dust and water resistance rating alongside MIL-STD-810G compliance, though age and rear cover adhesive breakdown will inevitably reduce environmental sealing over time.

Everyday performance

Powered by the Qualcomm Snapdragon 845 processor paired with 6GB of LPDDR4X RAM, the V40 ThinQ handles local audio playback, high-bitrate streaming, and general web browsing smoothly. Navigating Android 10—the final official operating system update the device received—remains reasonably responsive.

Where the V40 truly shines is media consumption. The Quad HD+ (3120 x 1440) P-OLED panel supports HDR10, rendering deep blacks and vibrant colors ideal for movie viewing. More importantly, plugging high-impedance audiophile headphones into the 3.5mm jack engages the dedicated Quad DAC. It easily drives demanding studio headphones with clear channel separation, ultra-low noise floor, and dynamic headroom that modern wireless-focused flagships simply cannot match.

Battery, durability, and longevity

Battery life has always been the V40's Achilles' heel. LG fitted the device with a modest 3300 mAh battery, which was barely adequate for a power-hungry 6.4-inch Quad HD+ panel when brand new. Today, original factory batteries suffer from severe capacity loss, resulting in short screen-on times and rapid drain under load.

In terms of physical durability, the glass sandwich design means dropping the phone without a protective case poses a high risk of shattering either the front display or rear backplate. Thermal management under heavy processing loads or continuous high-brightness playback can cause the Snapdragon 845 to throttle, accelerating battery drain further.

Common issues owners hit

Long-term owners and second-hand buyers frequently encounter a few predictable wear points on the V40 ThinQ:

• Severe Battery Degradation: Unexpected shut-offs at 15–20% charge or rapid depletion are widespread due to the small initial capacity and natural cell aging.
• USB-C Port Wear: The bottom Type-C port can loosen over years of cable insertions, causing intermittent charging, slow power delivery, or loss of wired data connection.
• P-OLED Burn-in and Cracks: Static navigation buttons and status bar icons can leave permanent ghost images on the display. Screen replacements require heating and removing the glued rear glass.
• 3.5mm Jack Debris & Wear: While durable, physical audio jacks tend to collect pocket lint over time, leading to loose headphone connections or failure to trigger the Quad DAC high-impedance mode.

Who it's for

The LG V40 ThinQ is no longer ideal as a primary daily driver for users who need modern Android software updates, banking app compliance, or multi-day battery endurance. However, it is an absolute bargain for:

• Audiophiles: Anyone looking for a dedicated Hi-Fi music player with microSD expansion to store massive FLAC or DSD libraries.
• Media Enthusiasts: Users who want a lightweight, secondary Wi-Fi display for streaming video, reading, or offline audio duty.
• Budget Hardware DIYers: Tinkerers who don't mind performing a straightforward battery swap to give a feature-packed device a second life.

Bottom line

The LG V40 ThinQ stands as a testament to an era when flagships prioritized wired audio excellence and hardware flexibility. While its small battery and frozen software roadmap restrict its viability as a modern primary smartphone, its phenomenal Quad DAC and sharp P-OLED display ensure it remains one of the best value multimedia tools on the secondary market.
