Keychron is quickly building momentum in the gaming mouse space, expanding its G-series lineup with two fresh releases: the Keychron G4 and Keychron G5. Arriving soon after the recently announced G3, these new models stick to a similar formula aimed at competitive players—symmetrical shapes, ultra-lightweight builds, 8K polling support, and flexible multi-mode connectivity for wired and wireless setups.
While Keychron has been making headlines for opening up parts of its hardware designs to the community, the G3, G4, and G5 aren’t included in that open-source list yet. For now, the focus is on performance, weight reduction, and battery life—three areas that matter most to esports-style gaming and fast-paced shooters.
Keychron G4 gaming mouse: ultra-light with 8K polling and tri-mode wireless
The Keychron G4 is built around the PixArt 3950 sensor and weighs 55 grams. Even though it’s the heaviest among the newest G-series trio, it still lands firmly in the lightweight gaming mouse category—ideal for quick flicks, rapid tracking, and long sessions without hand fatigue.
One of the biggest highlights is its tri-mode connectivity, letting you switch between wired use, 2.4 GHz wireless, and Bluetooth. For players who want the lowest latency and the smoothest tracking, the G4 supports an 8K polling rate in both wired mode and 2.4 GHz wireless mode. The sensor also scales up to 30,000 DPI, giving plenty of room for fine-tuning sensitivity across different games and monitor setups. Keychron also claims 0.41ms latency when using 2.4 GHz mode, a spec that targets competitive gamers who prioritize responsiveness.
Keychron G5 gaming mouse: lighter carbon fiber build and grippy surface
The Keychron G5 keeps the same general shape and performance approach as the G4, but it leans harder into weight savings and premium materials. Thanks to a carbon fiber construction, the G5 drops down to just 43 grams, making it noticeably lighter for players who prefer an effortless glide and minimal drag during fast movements.
Instead of using cutouts or perforations, the G5 keeps a solid shell and adds a honeycomb-pattern engraved surface designed to improve grip. It’s a clean approach for gamers who want a lightweight mouse without the feel (or dust buildup) that can come with open-shell designs.
Battery life and onboard controls: what separates the G4 and G5
Both the Keychron G4 and G5 include a 500 mAh battery, but their runtime differs slightly. The G4 is rated for up to 34 hours in 8K polling mode over a 2.4 GHz connection. Switch to 4K polling and it edges up to 36 hours, while 1K polling dramatically boosts endurance to as much as 130 hours.
The G5 stretches battery life a bit further across the board, helped by its lighter build. At 1K polling, the Keychron G5 is rated up to 153 hours, giving it an advantage for anyone who prefers charging less often.
There’s also a practical usability difference: the G4 includes dedicated buttons on the underside that let you adjust DPI and polling rate without opening software. That’s a convenient perk for players who switch between games or PCs and don’t want to rely on an app just to change core settings.
Keychron G4 and G5 price, colors, and availability
Keychron is positioning the two mice at different price points. The G4 comes in a single white color option and is priced at $80. The G5 is available in black only and costs $110, reflecting its carbon fiber construction and lighter weight.
Both mice are available through Keychron’s official sales channels, and the G4 has also appeared on Amazon at a slightly lower price—$5 less than the standard listing.
For gamers shopping for a lightweight symmetrical gaming mouse with 8K polling, the Keychron G4 and G5 offer two clear paths: the G4 focuses on strong performance with handy onboard controls at a more accessible price, while the G5 targets minimum weight and longer battery life with a more premium build.
