The second major thing to consider is the battery. On some level, any wireless mouse’s power concerns boil down to lasting the longest on a single charge, but figuring that out can actually be more complicated than you think. The official estimated battery life provided by the manufacturer reflects how long the mouse will last under ideal conditions—meaning that all of the RGB lighting is turned off. You should expect most wireless gaming mice to last less than half of their manufacturer-reported battery life with RGB lighting on. In our reviews, we request battery estimates for more practical conditions and do anecdotal testing to give you a real-world idea of how many days or weeks a mouse will last on one charge. Battery life can also vary based on what type of battery the mouse uses. Most of the wireless mice that we recommend feature rechargeable internal batteries, which can hold a charge that lasts for dozens of hours. Some gaming mice, particularly less expensive ones, eschew internal batteries for disposable AAs or AAAs, which last a very long time—often 100 to 200 hours—but need to be replaced when they run out of juice. As with our general guidance on finding the best wireless mice, we recommend getting one with a rechargeable battery for a few reasons. First, if a AA-powered mouse runs out of power and you don’t have replacement batteries on hand, you’ll need to drop what you’re doing to go out and get some. That may mean walking away from your PC mid-game to grab them from another room, or even having to leave the house. In contrast, most wireless gaming mice let you use their charging cables to set up a wired connection, so you can charge and play at the same time if you need to.  Second, mice with disposable batteries generate e-waste, which can be annoying to recycle or otherwise dispose of properly. (You can mitigate this by using rechargeable AA/AAA batteries, of course.) Needing to charge your mouse regularly may sound like a hassle on paper, but it rarely feels that way because it never reduces your ability to use the mouse. The only times we’ve had a dying battery affect a game were when we weren’t keeping track of mouse battery life. If plugging in your mouse still seems like a reach, some wireless gaming mice also feature wireless charging. Depending on the model, that means you put your mouse on a wireless charging pad or into some kind of dock to charge up. Wireless charging standards for gaming mice tend to vary by manufacturer. Some companies, like Corsair and HyperX, rely on the Qi wireless standard, so you can charge their mice on most third-party wireless charging pads. Razer’s high-end Ultimate and Pro tier mice rely on a Razer-specific wireless charging dock. Logitech G gaming mice support a special mousepad called the PowerPlay, which charges the mouse while you’re playing.
