Software

The Naga V2 Pro is fully compatible with Razer's modular software, Synapse 3. Synapse is embedded into an overarching software suite called Razer Central. From there, it is possible to install additional optional modules, such as Chroma Connect, Chroma Studio, or the highly sophisticated macro editor.

All settings are accessible through six tabs. "Customize" houses button remapping, which also includes a HyperShift function to enable a second set of button maps that can be accessed upon pressing a dedicated shift button. "Scrolling" has several options related to the scroll wheel. Five pre-defined and a custom stage are available, the latter of which can be further adjusted in terms of scroll tension (0–100), number of steps (8–96), and haptic feedback. Furthermore, the "Smooth Scroll" stage can be set to become adaptive (i.e., adjust tension based on scroll speed) if desired. "Performance" is used to adjust CPI for up to five levels, ranging from 100 to 30,000 CPI and in increments of 50. Polling rate can be set to 125, 500, or 1000 Hz. "Lighting" is detailed below. "Calibration" allows one to adjust the lift-off distance between three presets (low, medium, high), along with the option of setting up asymmetric cut-off. The fifth tab, called "Power," enables one to set the idle time (in minutes) after which the mouse enters sleep mode, as well as the battery status percentage at which Low Power mode is enabled. Low Power mode lowers the maximum tracking speed from 750 IPS (19.05 m/s) to 550 IPS (13.97 m/s) and maximum acceleration from 70G to 40G. Lastly, profile management is available, too.

All setting changes are applied immediately and saved to the on-board memory, so the software does not need to be running (or be installed) all the time. On my system, Synapse had a RAM footprint of 390 MB on average when running in the foreground, which doesn't change when minimized, be it to the taskbar or system tray. Furthermore, CPU usage saw a notable spike when the "Scrolling" tab was active. Upon exiting the application, several processes with an overall RAM footprint of 187 MB keep running. Remarkably, these processes continue to load if Synapse is set to not auto-start with Windows. The most convenient way of terminating these processes is to run any recent Razer mouse firmware updater.

Lighting

The Naga V2 Pro has two physical lighting zones, which are the logo at the back and 12-button side panel. Five pre-defined lighting effects are available: Audio Meter (lighting reacts to audio playback), Breathing, Reactive (lighting reacts to button inputs), Spectrum Cycling, and Static. Brightness can be adjusted, and for most effects, the colors are adjustable as well. By using Chroma Studio, creating more advanced effects is also possible. Additionally, the lighting can be configured to switch off in idle or when the display is turned off. Flipping the switch above the brightness slider disables illumination altogether.

Color accuracy and vibrancy are excellent throughout. Here's a short demonstration video in which I go through the Breathing and Spectrum Cycling lighting effects:

Battery Life

Razer states a maximum battery life of up to 150 hours in 2.4 GHz wireless operation and 300 hours in Bluetooth. This refers to continuous usage at a polling rate of 1000 Hz without illumination and scroll wheel usage for about 20% of the time. Hence, battery level will vary depending on scroll wheel usage, and typically be higher than indicated. The software includes a percentage-based battery life indicator with single-digit accuracy, which is in fact mostly reliable and accurate, though I've found the reporting to drift at times, and wired and wireless readings do not necessarily match. In my testing, when using 2.4 GHz wireless, a polling rate of 1000 Hz, the 2-button side panel, and full RGB lighting at 33% brightness, for each four hours of use, the battery indicator went down by 5%. Hence, we can assume that expected battery life with RGB enabled is around 80 hours.

After not moving the mouse for a short while, the Naga V2 Pro enters a rest state from which it can be woken up by either moving the mouse or clicking any button. The same goes for sleep mode, which is entered after a certain amount of idle time set in minutes within Synapse has passed.

Using the included USB Type-A to Type-C charging cable, I measured the charging speed during the constant current stage, which sits at around 0.377 A. The battery has a capacity of 1000 mAh.
