Logitech G305 LIGHTSPEED Review (2026): Long Life on One AA

This Logitech G305 LIGHTSPEED review looks at a wireless gaming mouse recommended in 2 expert buying guides that focuses on the basics: a precise sensor, a fast wireless connection and battery life that barely needs thinking about. It has no RGB, no rechargeable battery and no Bluetooth. What it offers is a stripped-back, travel-friendly design for gamers with small-to-medium hands who want reliable wireless play.

This review is based on Logitech's published specifications and on what independent expert reviews report. It is not hands-on testing. The aim is to explain what the numbers mean day to day and where experts say the G305 falls short.

Design and build

The G305 is a compact mouse, measuring 116.6 x 62.15 x 38.2 mm. Reviewers describe the shape as small and flat. That suits small-to-medium hands, but a common criticism is that it can feel cramped for larger hands and for a palm grip. If you have big hands, this is the first thing to check before buying.

Weight is a mixed story. The mouse is 99 g with the AA battery fitted and 75 g without it. The battery accounts for a real share of the total. Reviewers note that 99 g is heavy next to modern lightweight mice, so players who have moved to ultralight designs may find it noticeable.

Build quality gets praise. Experts talk about a solid, creak-free body. The main buttons use switches rated for 10 million clicks, and Logitech says it uses mechanical button tensioning for consistent, light clicks. There is no lighting at all, which suits anyone who wants a plain desk setup and doesn't want to pay for effects.

The design also solves a small but real travel problem: the USB receiver stores inside the mouse. Together with the compact shape, that makes it easy to drop in a laptop bag without hunting for a dongle.

Features and what they mean day to day

LIGHTSPEED wireless

The G305 uses Logitech G's 2.4 GHz LIGHTSPEED wireless through a USB nano receiver, with a report rate of 1 ms (1000 Hz). In practice, that means the mouse reports its position to the PC every millisecond, which is the figure wired gaming mice are usually judged by. Reviewers say it feels as responsive as a wired mouse, which is the main reason to consider a wireless gaming mouse at this level.

Wireless range is up to 10 m (33 ft). That is more than enough for a desk.

There are two limits. First, there is no Bluetooth, so the mouse connects only through the USB dongle. If you want to switch between a desktop and a tablet without using a receiver, this is the wrong mouse. Second, it can't be used wired, which matters because the battery is a standard AA. If the battery dies mid-session, you replace it. You can't plug in and keep playing.

Sensor and controls

The HERO optical sensor tracks from 200 to 12,000 DPI, with no smoothing, filtering or acceleration. Maximum speed is 400 IPS and maximum acceleration is 40 G. Those ranges cover everything from slow, precise aiming to fast sweeps at high sensitivity. Reviewers praise the tracking accuracy across the range. The "no smoothing, filtering or acceleration" point means the sensor passes your movement through as it is, which competitive players tend to want.

There are 6 programmable buttons. That is enough for a couple of in-game binds or shortcuts without overwhelming a compact body. Onboard memory keeps your settings when you move between PCs, so you can set the mouse up once and carry the configuration with you. Logitech G HUB software is optional. It is there if you want to customise, but the mouse doesn't require it.

Compatibility covers Windows, macOS and ChromeOS, so it isn't limited to gaming PCs.

Logitech G305 LIGHTSPEED review: battery and everyday use

Battery life is the standout. Logitech rates the G305 at up to 250 hours in Performance mode on one AA battery, or up to 9 months in Endurance mode. An alkaline AA is included in the box. Reviewers consistently praise this, and it is the clearest practical advantage of the AA approach.

The case for AA is simple. There is no charging routine to remember, and no built-in battery that wears out over the years. When the battery is flat, you swap it for a spare. The drawback is just as clear. It is non-rechargeable, so you need to keep spares around, and you can't top it up from a cable. People who prefer plugging in a USB cable at the end of the week will see this as a step backwards. People who would rather forget about charging for months will see it as a feature.

As a travel mouse, it makes sense on paper. It is compact, the receiver lives inside the body, and the battery lasts long enough that a trip is unlikely to drain it. The 2-year limited hardware warranty adds some reassurance on durability.

What experts like and what they criticise

The G305 averages 7.3/10 across 3 expert reviews. TechRadar scores it 4/5, Tom's Guide 3.5/5 and Tom's Hardware 3.5/5. It is also recommended in 2 expert buying guides. The scores point to a solid but not spectacular mouse, and the praise and criticism explain why.

What reviewers praise:

• Accurate tracking from the HERO sensor across its full DPI range
• Wireless responsiveness that feels like a wired mouse
• Very long battery life per AA, or up to 9 months in Endurance mode
• A receiver that stores in the body and a compact shape that suits travel
• A solid, creak-free build with durable main switches

A common criticism is:

• The non-rechargeable AA battery and the lack of a wired mode
• No Bluetooth, so it only works through the dongle
• Weight, since 99 g with battery is heavy next to modern lightweight mice
• A small, flat shape that can feel cramped for larger hands and palm grip

The good points are about core performance: sensor, latency, battery and build. The weaknesses are about convenience, ergonomics and weight. That split is useful because you can decide which side matters to you.

Who should buy it

The G305 is a good match if:

• You have small-to-medium hands and want a compact mouse
• You want wireless that responds like a wired mouse
• You travel with your mouse and like a receiver that stores inside the body
• You would rather swap a battery every few months than charge a mouse
• You don't care about RGB lighting
• You use Windows, macOS or ChromeOS

Who should skip it

Look elsewhere if:

• You want a rechargeable mouse, or one you can also use with a cable
• You need Bluetooth to connect to tablets or laptops without a dongle
• You have large hands or prefer a palm grip, where the small, flat shape is a common complaint
• You want an ultralight mouse, since 99 g with the battery is on the heavy side by current standards
• You want a lot of buttons, as there are 6 programmable ones

One way to soften the weight issue is to remember that the mouse is 75 g without the battery. But the battery is part of the design, so the 99 g figure is the realistic one.

How it fits in its category

The G305 sits in the mid-range part of the market. It is a wireless gaming mouse that spends its budget on the sensor, the connection and the battery, and leaves out extras such as RGB, Bluetooth, a rechargeable battery and an ultralight shell. If you want those features, you will be looking at a different kind of mouse. If you want the core wireless gaming experience done well, it is a sensible reference point. It isn't designed to win a spec war, and its expert scores reflect that.

Verdict

The G305 LIGHTSPEED is a focused wireless gaming mouse. The HERO sensor is accurate, the 1 ms wireless report rate feels wired-like, and a single AA battery can last up to 250 hours or up to 9 months in Endurance mode. The build is solid and the design is easy to travel with.

You pay for that focus in convenience and fit. There is no rechargeable battery, no wired mode, no Bluetooth, and a shape that suits small-to-medium hands better than large ones. With a 7.3/10 expert average, it is a good mouse for the right user and a poor fit for the wrong one. If your hands and habits match, it is easy to recommend. If you want ultralight, rechargeable or Bluetooth, check other options first.
