The Best Lightweight Wireless Gaming Mouse
Five gaming mice ranked on weight and battery life, where the ROG Harpe II Ace has the lightest weight; the M725 is the cheapest route in.
By Alex Morgan, PC Hardware Editor
12 min read5 products evaluated
A lighter wireless mouse takes less effort to start and stop, which helps with fast flicks in shooters. Every mouse here lists a weight of 65g or less and connects without a cable.
Rankings weigh weight, max DPI and battery life as the makers state them; if a maker skips max DPI, the guide says so rather than guess, since we have not benched them.

Our Picks
Lightest Mouse1 of 5
ASUS ROG Harpe II Ace
The ROG Harpe II Ace is built around track-on-glass sensing.
Best for
- Players who lift the mouse often at low sensitivity.
Skip if
- Its battery life is not published, which rules it out if you need that number.
Why we like it
On the spec sheet, it weighs 48g and offers a 42,000 max DPI. Its 48g weight is the lightest here; the M725 comes next at 49g. On polling rate it ties with the Viper V3 Pro Faker at 8,000Hz.
It is the only pick here with a wireless connection; the Viper V3 Pro Faker has a HyperSpeed 2.4GHz connection instead. The ROG Harpe II Ace's dongle works best on a front USB port or an extender near the mouse. Polling above 1,000Hz shortens battery life and needs a CPU with headroom. On price it sat fourth of 5, between the cheaper Viper V3 Pro SE and the pricier Viper V3 Pro Faker, at the time of writing.

How We Chose
Alex Morgan compared the manufacturer specifications, connectivity, warranty terms and compatibility of every pick. Figures come from the makers unless a third-party source is named; we did not test these products ourselves.
- How these picks were ranked
- We lined up five mice on weight, max DPI, battery life and polling rate, using each maker's published specs. We did not test them in-house, and max DPI and battery life are missing for at least one pick.
- What every pick has in common
- All 5, from the ROG Harpe II Ace to the Viper V3 Pro Faker, state weight and connection.
- Where the specs have gaps
- The Viper V3 Pro Faker gives no max DPI; the ROG Harpe II Ace and the M725 give no battery life.
- Price range
- At our last check the picks ran from the M725 (under $50) to the Viper V3 Pro Faker ($100 to $150).
