HERO is a revolutionary new optical sensor designed by Logitech G to deliver class-leading performance

and up to 10 times the power efficiency (compared to previous gen). HERO sensor delivers exceptionally accurate and

consistent performance with zero smoothing, filtering or acceleration from 200 to 12,000 DPI. G305 can save up to 5 profiles with up to 5 DPI levels each on the onboard memory.⁴

Through end-to-end engineering and design, Logitech G developed a robust wireless solution to solve the fundamental problems of latency, stability, and connectivity. The end result is LIGHTSPEED, a pro-grade wireless solution that achieves wired-like performance.

HERO sensor and LIGHTSPEED wireless deliver extreme efficiency to let you game for months. It delivers up to 250 hours run-to-die on just one AA battery. It can be adjusted to last up to 9 months of typical use in Endurance mode, which can be selected via Logitech G HUB.⁶Tested on Logitech G240 Gaming Mouse Pad Logitech G HUB, as well as the indicator light on G305, will notify you when 15% of battery remains.

At Logitech G, a wireless gaming mouse doesn’t need to be heavy. G305 is very light, coming in at only 99 grams, made possible thanks to the lightweight mechanical design and ultra-efficient battery usage.
