Logitech G502 X Plus vs Logitech MX Master 3S

The MX Master 3S lasts up to 70 days on a single charge. The G502 X Plus gets around 30 hours of active use, which translates to maybe 3-4 weeks if you're disciplined about turning it off. In practice, the G502 will interrupt your workflow with a dead battery at the worst possible moment. The MX Master 3S is the mouse you charge when you remember to, not when you have to.

The MX Master 3S connects to three devices simultaneously and switches between them with a dedicated button on the bottom. The G502 X Plus connects to one device, period. If you run a work laptop and a personal desktop, the MX Master 3S eliminates a second mouse entirely. That's not a feature — that's a different category of product.

The MX Master 3S has an electromagnetic scroll wheel that shifts between precise ratchet mode and frictionless hyperfast mode — you can fly through a 200-page document in seconds or scroll line-by-line through code. The G502 X Plus has a decent scroll wheel with a similar dual-mode concept, but it's mechanical and noticeably less refined. If you scroll through long documents, spreadsheets, or web pages all day, this difference will hit you within the first hour.

The HERO 25K sensor in the G502 X Plus is among the most accurate tracking sensors ever put in a mouse, and LIGHTSPEED wireless is genuinely indistinguishable from wired in competitive play. Add 13 programmable buttons versus the MX Master 3S's 7, and the G502 is simply the better gaming tool. But if you're not gaming, none of this matters — you're paying for precision you'll never use.
