Who Should Buy This#
The Logitech G305 LIGHTSPEED hits a sweet spot for gamers who want wireless performance without paying wireless prices. It delivers the same LIGHTSPEED technology found in mice costing three to four times more, packed into a compact, lightweight shell that works straight out of the box.
Perfect for:
- First-time wireless gamers who want to ditch the cable without worrying about input lag or dropped connections
- Competitive FPS players on a budget who need a reliable 12K DPI sensor and 1ms wireless for ranked matches
- Laptop gamers and LAN party regulars who need a portable, battery-powered mouse with a nano receiver that tucks inside the body
- Multi-device users who want one mouse for gaming and daily productivity across Windows, macOS, and Chrome OS
Design & Build Quality#
The G305 borrows its shell shape from the classic Logitech G Pro wired mouse, a form factor refined over years of esports feedback. At 116.8mm long by 62.15mm wide, it fits comfortably under claw and fingertip grips, though palm grip users with larger hands may find it compact.
The matte plastic shell resists fingerprints and provides a secure grip without added texture pads. Build quality feels solid with no flex or creaking, and the primary click buttons use separate mechanical switches rated for 10 million clicks. The scroll wheel offers tactile, notched feedback with a satisfying click that makes weapon switching or page scrolling precise and intentional.
Key Features#
LIGHTSPEED Wireless That Matches Wired Performance#
The G305 uses Logitech's LIGHTSPEED wireless technology, the same protocol found in their flagship G Pro X Superlight. It delivers a 1ms report rate at 1000Hz polling, which means your inputs reach the game as fast as a wired connection. In blind tests, professional players cannot distinguish LIGHTSPEED from a direct USB connection.
The included nano receiver plugs into any USB-A port and communicates over a dedicated 2.4GHz channel, avoiding the interference issues that plague Bluetooth mice. When you are done, the receiver stores inside the mouse body so you never lose it.
HERO 12K Sensor with Zero Compromise Tracking#
The HERO sensor is Logitech's proprietary optical sensor, delivering 200 to 12,000 DPI with 400+ IPS tracking speed and up to 40G acceleration. Unlike older sensors, HERO applies zero smoothing, filtering, or acceleration to your movements. What your hand does, the cursor replicates exactly.
You can set DPI in five customizable levels through Logitech G Hub software, or use the dedicated DPI button behind the scroll wheel to cycle through presets on the fly. A single onboard memory profile stores your settings directly on the mouse, so your sensitivity follows you to any computer without installing software.
250-Hour Battery Life on a Single AA#
The HERO sensor is not just accurate; it is 10 times more power-efficient than previous Logitech sensors. The G305 runs for 250 hours on one AA battery at the default 1ms reporting rate. Switch to the power-saving mode at 8ms polling and you can stretch that to roughly nine months of daily use.
The mouse ships with a Duracell AA battery pre-installed. When it finally runs low, a low-battery indicator in G Hub gives you plenty of warning. Swapping in a fresh battery takes five seconds by lifting the top shell. You can also drop in a lithium AA to shave roughly 9 grams off the total weight.
99g Lightweight Build for Reduced Fatigue#
At 99 grams with the AA battery installed, the G305 sits in the lightweight category without resorting to honeycomb cutouts or exotic materials. It is light enough to flick across a large mousepad without arm fatigue during extended sessions, yet heavy enough to feel controlled and deliberate in slow, precise aiming.
For users who want to go even lighter, swapping the standard AA for a lithium AAA battery with a tin foil adapter can bring the weight down to around 83 grams. The community has embraced this modification, and it works without affecting tracking or battery life significantly.
