Battery life is another concern in regards to wireless mice, but the G305 has some impressive figures in that department. A single AA battery will keep the mouse running for up to 250 hours with the previously mentioned 1ms response time—not too shabby for a mouse offering that level of performance. But if you’re just using the G305 for general work applications or surfing the web, you can drop it into “endurance mode” via Logitech’s software and the mouse will reportedly run for nine months on a single battery with an 8ms response time. That’s a handy feature for anyone who needs a laptop mouse for the road, since it can still offer precision gaming performance when needed. As someone who primarily plays first-person shooter (FPS) titles, like CounterStrike: Global Offense and Rogue Company, I'm eager for gaming mice that are so well-built that they help me grow better as player. Logitech's proprietary Hero sensor used in the G305 Lightspeed is the kind of technology that can help make that happen. The sensor is specced for a sensitivity range of up to 12,000 CPI. That's lower than the Mamba Wireless and Kain 200 Aimo's sensors, which each go up to 16,000 CPI. But for a mainstream gamer, 12,000 CPI should be sufficient. The Hero sensor can also hit a max velocity of over 400 IPS (inches per second) and handle up to 40G of acceleration. On the bottom of the G305 Lightspeed, you will find the same "Hero"-branded optical sensor used in Logitech's more expensive mice. Its resolution ranges from 100dpi to 12,000dpi, so don't expect quite the same amount of flexibility you would get from the 16,000dpi-maximum Razer Mamba. That said, at the upper fringes of mouse resolution, it's mostly a numbers game, as opposed to what you can actually perceive. Using it +8 hours a day, the AA cell consistently lasts for 3-4 months, with plenty of warning that the battery should be replaced. The long battery life is from an automatic sleep feature. While mercury-free alkaline cells are a disposal issue, they are much less so than Li-ion cells.

This makes the G305 Lightspeed more versatile and portable too. The only negative I see with this new mouse is its overly complex multiple buttons and USB port for programming or wi-fi reliability. The latter may have advantage for a gamer using a very large display, but I don't need that or a plethora of buttons. Next to where the battery fits is a compartment to carry the dongle for easy travel and making sure you don't lose your Lightspeed connection. Gaming Performanceof Logitech G305 Lightspeed

We mentioned the AA battery a moment ago. Logitech claims 250 hours of battery life from that AA cell in the G305 Lightspeed. However, that is only the case when the mouse is set to the default Performance mode in LGS. Another mode, called Endurance mode, is a choice alongside it. When enabled, Logitech says the battery life rises to a full nine months but the response time rises from 1ms to 8ms; in other words, an increase in latency is one of the trade-offs for conserving battery life. It's been done before, the wireless mouse for the frugal gamer—but done well is another matter. The Logitech G305 Lightspeed may be plain compared with the likes of competitors such as Razer's Mamba, but its strength comes from its guts, rather than its outer shell. The Logitech G305 Lightspeed Wireless only offers 12,000 DPI max, but we just use the word “only” here in comparison to other wireless gaming mice. A few of them offer 18,000 to 20,000 DPI, which means that on paper, Logitech’s offering pales in comparison. However, considering that most players won’t really know the difference between 8,000 DPI and 20,000K DPI, this isn’t a biggie.planned non-repairable mouse with a rechargeable cell soldered to a circuit board that needs charging more frequently, along with the attendant cables or adapters with declining capacity. Sadly, the Logitech G305 Lightspeed isn't rechargeable, which likely helped keep the price down. However, you can find similarly priced wireless gaming mouse that are rechargable for a similar amount of money. A Unifying receiver looks like the image below, and it does not work with products that are not Unifying compatible.

For all the office warriors out there who trade spreadsheets for killstreaks after hours, the Logitech G305 Lightspeed is your ultimate gaming companion. This wireless marvel is not just a mouse; it's an extension of your gaming prowess, designed to seamlessly fit into your professional and gaming lifestyle. I'd prefer a mouse with an easily available inexpensive replaceable cell. It would be superior to a If this Logitech mouse is anything like the single AA Microsoft Bluetooth Mouse I have been using for the past 2 years (or Logitech wireless mice I own) that battery is a plus, not a minus. Logitech’s wireless Lightspeed communication tech remains unsurpassed. If you’ve ever played an intense game with a laggy, run-of-the-mill wireless mouse you know the irritation of always wondering if that last death was brought on by slow response from the mouse to the receiver. But as stated earlier, the G305 feels just like a wired gaming mouse. While I’m unable to scientifically test Logitech’s claims of 1ms response with this mouse, I can certainly attest the "in-hand" results felt like it was wired.Now, let's talk about the design. It's sleek, ergonomic, and built for hours of comfortable gameplay. The ambidextrous shape ensures it's suitable for all hand sizes and grips, making it a versatile choice for any gamer. Its lightweight build is a blessing during marathon sessions, ensuring fatigue doesn't slow you down. As is the case with most Logitech peripherals, every device can be controlled and modified using the company’s Logitech Gaming Software. The latest version of LGS provided to me during this review carries on the same streamlined features and ease of use as the previous versions. While there’s no flashy lighting or customizable RGB effects on the G305, there is a bit of customization available. Whilst we will do everything we can to meet the delivery times above, there may be factors outside of our control and we cannot guarantee delivery within this time frame.

I'm still not sure if there's a point where a mouse can be TOO light. I personally haven't found that point yet. I've used lighter mice than this and didn't notice much of a difference. I don't feel any extra fatigue using this one. Make no mistake though, this is a light mouse. But here's the real clincher - the battery life. The G305's efficiency is nothing short of impressive. A single AA battery can last for months, even for avid gamers who squeeze every ounce of performance out of it.Instead of a rechargeable battery, the G305 Lightspeed runs on a single AA battery, Logitech claims you can get up to 250 hours of gaming off one battery. That’s way more than the 50 hours Razer claims with the Mamba Wireless. You can get a battery life reading from the G Hub software. Also helpful is the LED under the scroll wheel, which flashes red when the battery's dying. Bottom Line Logitech’s Lightspeed wireless connectivity has always been on point, and the one on Logitech G305 Lightspeed Wireless is no different. It’s very responsive with no noticeable lags even when you’re using it a little farther away from your gaming PC. We’re able to get accurate responses from 10 feet away, in fact. Using the mouse about 15 feet away and from another room, we have experienced some lags, but in the real world, no one would be doing that anyway so that hardly matters. The curvature on top of the G305 is subtle and is very comfortable in the palm of the hand. I personally prefer playing with a palm grip, but I found the G305 equally comfortable and all of its six buttons easy to access with a claw grip, as well. There are two standard thumb buttons on the left side of the G305, and while this mouse has a symmetrical design that would work for both lefties and righties, the thumb buttons are not swappable like they are on the G903. The mouse wheel is wide and scrolling is smooth and pleasant. To determine if your Logitech device is Unifying compatible, look for this Unifying logo on your device.
