Overview
The Razer DeathAdder V4 Pro is the pinnacle of Razer’s iconic ergonomic gaming mouse lineage, arriving in 2026 as an ultra-lightweight wireless powerhouse that improves on the acclaimed V3 Pro in every measurable way. At just 56g and with a 150-hour battery life at 1,000Hz polling, the V4 Pro is a marvel of engineering — lighter and longer-lasting than any previous DeathAdder without compromising the ergonomic shape that has made the series beloved by millions of gamers worldwide.
The centrepiece is Razer’s new 45,000 DPI Focus Pro optical sensor with 8,000Hz HyperPolling via the included dongle, delivering sensor data to your PC eight times per second for imperceptibly smooth tracking that obliterates traditional 1,000Hz mice in fast-paced competitive play. Combined with Gen-3 optical switches rated to 90 million clicks and Razer SpeedFlex cable (though wireless is the recommended mode), this mouse is built to last for years of intensive daily use.
USB-C charging means a universal charging solution, and a quick 15-minute charge delivers 2.5 hours of play — you’ll rarely need to think about the battery given the 150-hour runtime.
Key Features
45,000 DPI Focus Pro Optical Sensor: Razer’s most accurate sensor to date with True 45K DPI tracking, 750 IPS tracking speed, and zero hardware acceleration. Tracks flawlessly on virtually every surface including glass.
8,000Hz HyperPolling: Reports cursor position 8x more frequently than standard gaming mice. The result is noticeably smoother cursor movement in fast-paced scenarios — a genuine competitive advantage in shooters.
56g Ultra-Lightweight Design: Significantly lighter than the V3 Pro, achieved through a refined internal chassis. The ergonomic right-handed shape is preserved in full so grip comfort is identical to the models that built the DeathAdder’s reputation.
150-Hour Battery Life: At 1,000Hz polling, the V4 Pro lasts 150 hours — up from 90 on the V3 Pro. At 8,000Hz it drops to around 28 hours, still far longer than most competing flagship wireless mice.
Gen-3 Optical Switches: Rated to 90 million clicks with near-zero debounce delay, these switches eliminate the double-click issues that have plagued mechanical switch mice over time. The click feel is crisp, tactile, and consistent.
Razer HyperSpeed Wireless: Low-latency 2.4GHz wireless connection is indistinguishable from wired in real-world play. Connects via included USB-A dongle with an optional USB-C adapter included in the box.
USB-C Charging: Universal fast charging — 15 minutes for 2.5 hours of play. No more proprietary charging docks or cradles to carry around.
Who Is It For?
The Razer DeathAdder V4 Pro is the mouse for competitive PC gamers — FPS players in particular who demand precision, low weight, and long battery life. The ergonomic right-handed shape suits palm and claw grippers with medium-to-large hands, and the 8,000Hz polling gives it a genuine edge in fast-twitch competitive titles like CS2, Valorant, Apex Legends, and similar games.
