Logitech G305 Lightspeed Review: One AA Battery Buys 250 Hours At $60

HERO tracking and a 1 ms radio

Logitech specifies the G305's HERO sensor at 200 to 12,000 DPI, a maximum tracking speed of 400 inches per second and 40 G of acceleration, both figures measured on the company's G240 cloth pad. The sensor applies no smoothing, filtering or acceleration across that range. HERO's other purpose is efficiency: Logitech describes a power management scheme that adjusts frame processing to the speed of the mouse, and credits it with up to ten times the efficiency of the previous sensor generation.

The radio is Lightspeed, Logitech's proprietary 2.4 GHz link, running at a 1,000 Hz report rate, which the company rounds to 1 ms. There is no Bluetooth, so the mouse only works with its receiver, and that receiver stores inside the shell for travel. A 32-bit ARM microprocessor handles the link. System requirements are Windows 7 or later, macOS 10.13 or later, or ChromeOS, plus a free USB port; G HUB software is optional and needs an internet connection to download.

One AA, 250 hours, 99 grams

Logitech's headline number is 250 hours of run-to-die use on a single AA cell, with the footnote that battery life varies by user and cell. In Endurance mode, selected in G HUB, the company says the mouse can stretch to about nine months of typical use, trading report rate for runtime. Both G HUB and an indicator light on the mouse warn at 15 percent remaining, so a dead cell mid-match is a failure of attention, not of design.

The cost is mass. The G305 is listed at 99 grams, or 3.49 ounces, and Logitech has not said whether that figure includes the cell. Logitech's own feature copy headlines the mouse as Ultra-Lightweight and credits the 99 grams to lightweight mechanical design and efficient battery use, which is the company framing its own number rather than measuring it against another mouse. What the 99 grams cost in hand depends on how you hold the mouse and on how long a session runs, neither of which Logitech publishes.

Six buttons on a small shell, thumb keys on the left

The G305 has six programmable buttons: left and right primaries, a clickable scroll wheel, a DPI button behind the wheel and two side buttons, which Logitech's own photos place on the left flank. Logitech rates the primary switches for 10 million clicks and uses what it calls a mechanical button tensioning system, a spring arrangement under separated button pieces meant to keep left and right click force consistent. Onboard memory holds one profile, so a DPI setup made in G HUB follows the mouse to another computer, but only one.

The shell is 116.6 mm long and 62.1 mm wide, which puts it at the small end of gaming mice. With thumb buttons on one flank only, right-handed use is assumed, and the low 38.2 mm height suits claw and fingertip grips more than a full palm grip. Inside the box are the mouse, the Lightspeed receiver and paperwork; Logitech's contents list names the mouse as G304, a discrepancy the page does not explain.

Fifty-nine ninety across the range, and the wired alternative

Black, white, mint, blue and lilac all list at $59.99 on the US Logitech G store, read on 2026-10-04, and no markdown is printed on the single-item price. The only offer block beside the buy box is conditional — it needs a second Logitech G mouse, keyboard or headset in the same order — so it does not lower the price of this mouse on its own. Four of the five colors show as in stock; lilac is flagged as limited availability.

The buy box states free shipping in 3-5 business days on all orders, while the order FAQ says shipping rates, methods and free-shipping thresholds vary by destination, so the shipping line is that page's US wording, not a standing rule. logitechg.com purchases can be returned for 30 days through the company's returns portal.

Logitech's own wired G203 Lightsync is the obvious comparison, and the gap is $25: $34.99 for the black G203 against $59.99 for the black G305. The G203's lilac, blue and white variants list at $39.99, so the wireless premium lands between $20 and $25 depending on which pair of colors you line up. The G305's case over it is the receiver and the HERO sensor, and if a cable does not bother you the G203 is the cheaper answer. Both carry a limited hardware warranty of two years; Logitech's order FAQ says warranty length varies by product and refers buyers to the packaging or the support site for the exact term, and the G305 page states two years directly.

Skip it if weight or hand size is the constraint

The G305 suits large hands badly. A 116.6 mm shell with a 38.2 mm hump leaves a palm-grip player with fingers overhanging the front, and no amount of sensor quality fixes an uncomfortable shape. Players chasing the lightest possible mouse should also pass: 99 grams is the only weight the page prints, and the five variants it lists differ by color, not by shell.

It is also the wrong buy for someone who needs Bluetooth, lighting, or more than one stored profile, because it has not one of those. Where it fits is the large middle: a player upgrading from a basic wired mouse who wants a real gaming sensor, a wire-free desk and a battery that gets replaced a couple of times a year. At $59.99 the case rests on the Lightspeed receiver, because Logitech's own wired G203 lists at $34.99 in black.
