Note that at any time, you can hook up the included cable to charge while playing. That's below Razer's estimated battery life, but still pretty good for a wireless mouse. It ended up lasting 62 hours before needing a charge. Using the mouse primarily in the HyperSpeed wireless mode with RGB lighting on, I found the mouse lost around 1-2% of its total charge per hour. When using the HyperSpeed dongle connection, the battery life figure drops to an estimated 70 hours. Razer touts up to 120 hours battery life without RGB lighting using the Bluetooth connection. Sliding across the battlefield was smooth and precise, with nary a mis-click that I could attribute to the mouse. High CPI settings were helpful during hard strategy sessions in A Total War Saga: Troy, my current go-to strategy title. The same was true for nailing pinpoint arrows while hunting in Horizon Zero Dawn, where I changed sensitivity on the fly, adjusting upwards for movement but using lower levels for aiming. Playing Mafia: Definitive Edition, I settled on 1,600 CPI and found it easy to drop gangsters with well-placed headshots. The matte plastic finish gives them great differentiation over the textured side panel, so you can always feel where they are under your thumb and the divot between the two buttons is big enough that you always know which one you're pressing. The side buttons require a little more force to activate, meaning you're unlikely to accidentally press them. However, we've found that they lack the same tactile feel as gaming mice that opt for traditional (and quality) mechanical switches. I had no issues with activation or double clicking my clicks were always responsive, even when I was clicking like a mad man in Final Fantasy XIV. Razer's optical switches under the left and right mouse buttons are rated as durable up to 70 million clicks. The company points to other features, like Smart Tracking and Motion Sync, to ensure smooth motion. The Razer sensor has a 99.6% resolution accuracy at 650 IPS (inches per second) and can handle up to 50G acceleration. Between the two sensitivity buttons and the Razer Synapses software, you can change the sensitivity of the mouse anywhere from 100-20,000 CPI with five different adjustable steps.

Like the wired version of this mouse, the DeathAdder V2 Pro uses the Razer Focus+ optical sensor. Walking into another room in my apartment, the connection became a little spotty, but for those gaming in the living room, the DeathAdder V2 Pro will keep you covered. With the HyperSpeed connection, I had no issues with the mouse's tracking, and that continued even when I moved it even further away from my PC. The DeathAdder V2 Pro offers three options for connectivity, and you can swap between them via the switch on the bottom.
