The Logitech 309 LIGHTSPEED is an affordable and reliable mouse designed to meet the needs of a variety of users. One of its standout features is its compatibility with Logitech POWERPLAY, which allows users to swap out the AA battery for the Logitech wireless charging system, thus making the mouse lighter than the previous generation model. However, it is important to note that the POWERPLAY system is sold separately at a relatively high price and comes with its own set of pros and cons.
The G309 LIGHTSPEED is known for its very low latency, high responsiveness, and accuracy, with adjustable DPI settings to suit different preferences. Priced at a suggested retail price of $79.99 USD, it is available in two colorways: Black and White. Overall, the G309 LIGHTSPEED is a lightweight mouse featuring hybrid optical-mechanical switches, making it suitable for mixed usage. It is marketed as an upgrade from the previous generation model, with improved battery life being the most significant change.
WHAT YOU NEED TO KNOW
THE GOOD

THE REST
- Battery Life
Logitech is claiming 300+ hours with LIGHTSPEED wireless, 600+ hours in Bluetooth mode, with the option of using their POWERPLAY wireless charging system instead of an AA battery, though Labs cannot verify this through testing.

The G309 LIGHTSPEED is a good step up from the previous gen G305 for users looking for an upgrade.
