Logitech G305 vs Razer DeathAdder V3 HyperSpeed

Both excellent — G305 edge in efficiency

The HERO 25K and Focus X 26K are both flagship-tier sensors with zero meaningful difference at any DPI setting a human can practically use. Both have no smoothing, zero acceleration, and excellent tracking on cloth and hard pads. The HERO 25K has a slight edge in power efficiency — one reason the G305 achieves 250 hours vs the DeathAdder's 100 hours on the same AA battery. At the DPI ranges gamers actually use (400–3200), you cannot tell these sensors apart.

DeathAdder wins for right-handed players

This is the most important category for most buyers. The G305 uses an ambidextrous, relatively flat shape that works but doesn't excel for any hand size or grip style. The DeathAdder V3 HyperSpeed uses Razer's refined right-hand ergonomic form — a thumb ledge, curved sides, and a hump that centers the hand naturally. For palm and claw grip right-handed players, the DeathAdder shape reduces fatigue significantly over long sessions. Left-handed gamers or those who prefer flat mice should choose the G305.

DeathAdder edges ahead at 88g vs 99g

11g lighter on the DeathAdder V3 HyperSpeed — the equivalent of about 3 US coins. In a lab test, you'd struggle to notice it. In a 4-hour gaming session, the difference is more perceptible than the numbers suggest, especially during fast flicks. Both mice are significantly heavier than true ultralight options (60g class). The G305 at 99g with 1 AA battery is competitive for its price; the DeathAdder's 88g (battery included) is better for serious play without breaking the budget.

G305 dominates — 250hr is extraordinary

The G305's 250-hour battery is one of the most impressive specs in gaming peripherals at any price. Playing 4 hours a day, you change the AA battery roughly every two months. The DeathAdder V3 HyperSpeed's 100 hours is still excellent — about 25 days at the same usage. Both use replaceable AA batteries rather than USB-C charging, which means zero downtime waiting for a charge. For travel or multi-PC setups, the G305's battery life is a genuine advantage. For most home gamers, 100 hours is more than sufficient.

Dead heat — both 1ms 2.4GHz

LIGHTSPEED and HyperSpeed are both 2.4GHz proprietary wireless protocols targeting 1ms report rate. In blind testing, players cannot distinguish between them. Both are fast enough for professional esports play. Neither supports Bluetooth — you need the USB nano receiver for either mouse. The receivers are small enough to leave permanently plugged into a PC. If you already have a Logitech G wireless device with a LIGHTSPEED receiver that supports pairing multiple devices, the G305 could share it (depending on receiver generation). Otherwise, they're equivalent.

G305 is the value king; DeathAdder earns its premium

At $40 with LIGHTSPEED wireless and a flagship sensor, the G305 is arguably the most value-dense gaming mouse ever made. You genuinely cannot get LIGHTSPEED wireless + HERO 25K for less. At $70, the DeathAdder V3 HyperSpeed costs 75% more for 11g less weight, a better ergonomic shape, and a slightly newer sensor. Whether that premium is justified depends on whether the ergonomics matter to you. For a first wireless gaming mouse or a budget gaming setup, the G305 is the easy recommendation. For players who've been using a DeathAdder and want wireless, the HyperSpeed version is an excellent upgrade.

G305 lasts 2.5× longer on the same AA battery. Real advantage for infrequent charging.

DeathAdder's right-hand contour reduces fatigue. G305 is ambidextrous with no special shaping.

11g lighter on the DeathAdder. Noticeable in long sessions; not a dealbreaker at either weight.

$30 gap. G305 wins on pure value; DeathAdder earns its price through ergonomics and lighter build.
