The black G305 LIGHTSPEED is a wireless mouse with a HERO sensor rated up to 12,000 DPI, six programmable buttons and a 1000 Hz report rate, powered by one replaceable AA battery (99 g with the battery fitted).

Specifications checked 11 Sept 2026Manufacturer specifications, not a hands-on test.
Logitech rates the AA battery at up to 250 hours of continuous use in performance mode, or up to nine months in Endurance mode, and the USB receiver stores inside the mouse.
The HERO sensor offers five on-the-fly DPI settings, and G HUB saves one onboard profile so settings travel with the mouse.
There is no RGB lighting or wheel tilt, the thumb buttons are on the left side only, and Endurance mode reduces tracking performance.
