The Logitech G305 Lightspeed is a compact wireless gaming mouse built around Logitech’s HERO 12K sensor and 1ms Lightspeed wireless connection. It strips away RGB lighting, extra weight, and premium materials in favor of a simple goal: reliable wireless performance without the usual latency or battery-life trade-offs.
It’s aimed at competitive and casual gamers alike who want a no-fuss, budget-friendly wireless mouse for FPS, MOBA, or everyday desktop use. If you prioritize low weight, long battery life, and consistent tracking over customization and RGB flair, the G305 is worth a close look.

Design & Build
The G305 uses a right-handed ergonomic shape similar to the wired G203, with a moderate hump and textured side grips. At 99g with a single AA battery installed, it’s noticeably lighter than most wireless mice in its price range, which helps during fast flick shots and long sessions. The shell is matte black plastic with minimal branding—no RGB, no chrome accents. Build quality feels solid for the price, though the plastic can feel slightly hollow when tapped, and the exposed battery compartment lid isn’t the most premium touch. The scroll wheel has clear, tactile steps, and the six programmable buttons are logically placed, though the DPI shift button on top takes some getting used to.
Performance
The HERO 12K sensor tracks accurately up to 12,000 DPI with no smoothing or acceleration artifacts at typical gaming sensitivities (400-1600 DPI), and Lightspeed wireless technology delivers response times indistinguishable from a wired connection in practice. Click latency is excellent for the price tier, and the mouse feels responsive in fast-paced shooters. Battery life is a genuine highlight—Logitech rates it up to 250 hours on a single AA battery, and real-world use with occasional RGB-free operation confirms weeks of use before a swap is needed. The included USB dongle stores inside the mouse body, which is a thoughtful touch for travel. On the downside, there’s no wired mode as a backup, and the mouse ships with a single AA battery rather than the more premium rechargeable options found on step-up models.
Pros & Cons
- Excellent battery life—up to 250 hours per AA battery
- Lightspeed wireless delivers near-zero perceptible latency
- Lightweight 99g design reduces fatigue during long sessions
- Accurate HERO 12K sensor with no tracking artifacts at gaming DPI ranges
- No RGB lighting or software lighting customization
- Uses a single AA battery instead of rechargeable or USB-C charging
- No wired mode for tournament play or dead-battery backup
Alternatives to Consider
If you want more programmable buttons and adjustable weights for a heavier, more customizable feel, the Logitech G502 Lightspeed offers 11 buttons and POWERPLAY wireless charging compatibility at a higher price. Budget-conscious buyers who don’t need wireless can look at the Logitech G203 Wired, which offers similar button count and LIGHTSYNC RGB for less. Those wanting the G305 experience at a lower cost might consider the Logitech G305 Lightspeed (Renewed) in black or white, which offers the same core performance at a discount, though with the usual caveats of buying refurbished hardware.
Frequently Asked Questions
Does the G305 require a battery at all times?
Yes, it runs exclusively on a single AA battery with no built-in rechargeable cell. Logitech includes one AA battery in the box to get started immediately.
Is the G305 suitable for competitive gaming?
Yes. The Lightspeed wireless protocol and HERO sensor deliver latency and accuracy on par with wired mice, making it a legitimate choice for competitive FPS and MOBA titles despite lacking a wired fallback mode.
Can I customize the buttons and DPI settings?
Yes, using Logitech’s G HUB software you can remap all six buttons, adjust DPI stages, and create per-game profiles stored in onboard memory.
How does it compare to the G502 Lightspeed?
The G305 is lighter, simpler, and cheaper, but the G502 Lightspeed offers more buttons, adjustable weights, RGB lighting, and PowerPlay wireless charging pad compatibility for users who want a more premium, customizable experience.
Verdict
The Logitech G305 Lightspeed remains one of the best value wireless gaming mice available, delivering wired-quality performance, exceptional battery life, and a lightweight design without demanding a premium price. It sacrifices RGB lighting and charging convenience, but for gamers who care primarily about tracking accuracy and responsiveness, those are easy trade-offs to accept.
