Logitech G305 Lightspeed Wireless Gaming Mouse - Compact 99 g Wireless Control With 12,000 DPI

Logitech G305 Lightspeed Wireless Gaming Mouse delivers up to 12,000 DPI tracking, a 1ms wireless report rate and around 99 g weight with battery for precise control in fast PC games. For competitive and casual players, its single-AA design and 250-hour battery life matter most.

Logitech G305 Lightspeed Wireless Gaming Mouse brings Logitech's HERO optical sensor and compact, lightweight shell to PC gamers who want reliable wireless control without a premium price tag. With up to 12,000 DPI tracking, a 1ms report rate and a quoted 250 hours of gaming on a single AA battery, it targets players who prefer a simple six-button layout over heavier, feature-loaded mice.

Design, Dimensions And Weight

The G305 Lightspeed uses a small, symmetrical shell that measures about 4.59 inches long, 2.45 inches wide and 1.50 inches high, according to one detailed hardware review that lists its external dimensions as 4.59 x 2.45 x 1.50 inches (116.6 x 62.2 x 38.2 mm).That same review puts the weight at 3.49 ounces, or roughly 99 g, including the AA battery, while Logitech's own technical specification sheet lists 75 g without battery and 99 g with one AA cell.Logitech's specification page confirms the height, width and depth values and the difference between the bare shell and the complete mouse with battery in place.

The plastic shell omits RGB lighting entirely and instead relies on a single indicator LED on the top surface. Logitech's technical documentation notes that the G305 includes one LED for status indication and supports a single onboard memory profile for storing DPI and button assignments.That same spec sheet also points to PTFE feet tested to a 250-km glide range on a Logitech G240 mouse pad, as well as mechanical button tensioning on the primary switches to keep clicks feeling consistent over time.

Sensor, Performance And Wireless Technology

At the heart of the G305 Lightspeed is Logitech's HERO sensor, an optical sensor designed specifically for gaming that, according to Logitech's specifications, supports a resolution range between 200 and 12,000 DPI without built-in smoothing, acceleration or filtering.Logitech's spec listing also states that the sensor can handle maximum acceleration of 40 G and maximum speed of 400 inches per second when tested on a G240 gaming mouse pad. A test-focused article on this mouse echoes those numbers, describing the HERO sensor as delivering 12,000 DPI sensitivity and up to 400 IPS tracking for competition-level play.An independent review reiterates the 12,000 CPI figure and 1,000 Hz polling rate, and notes that the mouse does not introduce smoothing or acceleration.

Wireless communication relies on Logitech's Lightspeed technology, a proprietary 2.4 GHz radio link. Logitech's technical documentation identifies the wireless protocol as "Logitech G 2.4 GHz Wireless Technology" and lists a USB report rate of 1 ms at 1,000 Hz, with a wireless range up to 10 m or 33 ft.The same spec sheet notes that the mouse connects via a USB 2.0 nano receiver identified as model C-U0008, and that the report rate is adjustable through software, though competitive use typically sticks to the 1,000 Hz setting.

Unlike some higher-priced models that include Bluetooth or multiple wireless channels, the G305 focuses on the one Lightspeed radio link and does not ship with a wired cable. A hardware review describes the connectivity as a single USB Type-A receiver with no wired option and lists six programmable buttons, no lighting zones and a microprocessor based on a 32-bit ARM chip for processing clicks and movement data.That feature table emphasizes that the mouse aims at performance rather than a feature-heavy configuration and that its six-button layout covers left and right click, a clickable scroll wheel, two thumb buttons and a top-mounted DPI cycle button.

Buttons, Durability And Layout

Logitech's specification sheet identifies the G305 Lightspeed as a six-button design with mechanical button tensioning on the primary switches. The documented layout includes left and right primary buttons, the scroll wheel button, forward and back buttons on the left side and a dedicated DPI button behind the wheel; all six are programmable with Logitech G Hub software.Logitech's technical listing states that the main buttons are rated for 10 million clicks and that the PTFE feet are tested for a glide distance of 250 km, which places the expected lifespan within typical gaming mouse ranges.

From an ergonomics perspective, one hardware review describes the G305 as a right-handed shape with symmetrical contours and no dedicated left-handed support on the side buttons, but notes that the overall body is compact enough to suit claw and fingertip grips for many users.That review calls out the lack of a free-spinning scroll mode and the absence of extra macro rows, but frames these trade-offs as expected in a budget-focused mouse meant to keep weight down and keep the layout straightforward.

Battery System And Endurance Modes

Instead of an internal rechargeable pack, the G305 uses a single replaceable AA battery mounted under the top shell. Logitech's technical documentation specifies that the mouse ships with one AA alkaline cell and supports either alkaline or lithium AA batteries, with the battery compartment accessible when the top cover is removed.The same document quotes battery life in two modes: up to 250 hours of non-stop gaming in Performance mode at the standard 1 ms report rate, and up to nine months in an Endurance configuration optimized for standard desktop use. These figures are repeated by a spec sheet distributed by a US electronics retailer, which notes that switching to endurance mode via Logitech G Hub software can extend usage toward that nine-month mark and that both performance and endurance estimates depend on the user's activity patterns and the battery's discharge profile.A retailer-specification document also repeats the 250 hours claim and underlines that this figure assumes continuous game-level use.

A hardware review that tested the mouse in real play mentions that the G305's battery compartment includes storage for the nano receiver, making the mouse easier to transport while protecting the small dongle from loss.That piece points out that the decision to rely on AA batteries keeps the overall weight slightly higher than some ultralight wired mice, but also removes the need to manage charging cables or docks, which some users may find more convenient.

Software Support And Onboard Memory

The G305 Lightspeed integrates with Logitech G Hub, the company's configuration software for gaming peripherals. Logitech's technical documentation states that the mouse offers one onboard memory profile, allowing users to store a custom DPI ladder and button assignments directly on the device so that these settings persist across different computers without needing to reapply them every time.The same technical sheet notes that advanced button customization and DPI configuration require the G Hub software, but standard plug-and-play use works via the operating system's default HID drivers.

Independent testing emphasizes that the lack of RGB lighting means fewer features to configure, but does not reduce functional flexibility. A feature breakdown lists six programmable buttons and one profile, and mentions that users can set multiple DPI steps within the 200 to 12,000 range and then cycle through them using the top-mounted DPI button.The review suggests that this setup can work adequately for players who use different sensitivities across game genres or who need a low-DPI option for precise aim and a higher setting for rapid cursor movement during desktop use.

Price Positioning In The US Market

In the United States, the G305 Lightspeed Wireless Gaming Mouse is positioned as a budget-friendly wireless device rather than a premium flagship. A US-focused review notes that the mouse launches with a list price around $49.99 but frequently appears on sale, highlighting an example sale price of $39.95 at a major online retailer while still referencing the higher official price point.That price-focused review describes the mouse as a "budget" option within the wireless gaming segment, which aligns with the documented list price and the typical discounting pattern.

Another evaluation of the G305 Lightspeed frames its price similarly, stating that the mouse carries a $49.99 MSRP in the US, but "often on sale for less" and calling attention to how that price point undercuts some of Logitech's own more feature-rich wireless models and many competitors' midrange devices.In that review, the price section situates the G305 between true low-end wired mice and expensive wireless flagships, suggesting it can appeal to players who want a responsive wireless sensor without paying for extra buttons or lighting systems.

Comparison With Other Logitech Gaming Mice

Within Logitech's gaming lineup, the G305 Lightspeed sits below more recent models like the G Pro X Superlight in both price and feature count. Whereas the G305 uses a single AA battery and weighs about 99 g with that battery installed, the Pro X Superlight, according to Logitech's own marketing, targets a significantly lower weight with a built-in rechargeable pack and more advanced switches, putting the G305 clearly in the heavier, more basic category for weight-conscious players. Reviews for the G305 often mention that, while it does not reach ultralight territory, its weight is still manageable for most grip styles and sits notably below some older wireless mice that exceeded 110 g or more.

Compared with wired budget mice built around office designs or simple gaming shells, the G305's HERO sensor and Lightspeed wireless link move its performance closer to enthusiast devices. Its 12,000 DPI range and 400 IPS speed figures match or exceed those of some midrange wired competitors that top out near 8,000 DPI with lower tracked velocities. At the same time, the absence of RGB lighting, extra side buttons or adjustable weights keeps the cost lower and the feature set simpler, which trade press reviews often highlight as part of its appeal to value-focused buyers who prioritize sensor responsiveness and wireless reliability over a long checklist of extras.

Use Cases, Strengths And Limits

For US gamers who prefer compact mice and do not need more than six programmable buttons, the Logitech G305 Lightspeed Wireless Gaming Mouse offers a blend of performance metrics and straightforward design that fits into many desktop setups. Its 4.59-inch length and 99 g weight with battery make it suitable for small to medium hands and for claw or fingertip grips, though players with very large hands or a strong preference for palm grips may find the shell a bit short. The HERO sensor's 200 to 12,000 DPI range and 400 IPS speed capability mean it can handle both low-sensitivity aim and rapid cursor movement, and the 1 ms Lightspeed wireless link aims to keep input lag indistinguishable from wired performance in typical gaming conditions.

On the practical side, the replaceable AA battery system with an estimated 250 hours of gaming time in performance mode and up to nine months in endurance mode reduces charging management but adds slightly to the mass compared with internal lithium packs used in some modern lightweight mice. The absence of RGB lighting and lavish design flourishes pushes the G305 toward a discrete, minimalist look that can fit in both home gaming setups and office environments, though anyone seeking elaborate lighting effects or extensive macro support may look to higher-priced Logitech models or competitors. Taken together, the documented specifications suggest that Logitech G305 Lightspeed Wireless Gaming Mouse is best suited to players who want solid sensor performance, reliable wireless operation and a compact shell at an accessible price, and who are willing to trade away rechargeable batteries and visual flair to keep the cost down.
