Software

The Razer DeathAdder V2 Pro is fully compatible with Razer's staple software suite, 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 five 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. "Performance" is used to adjust the CPI for up to five levels, ranging from 100 to 20,000 CPI and in increments of 50. Furthermore, x and y-sensitivity can be adjusted independently if so desired. Polling rate can be set to 125, 500, or 1000 Hz. "Lighting" is discussed below. "Calibration" allows one to adjust the lift-off distance in a highly detailed manner. One can either set LOD to pre-defined levels of 1, 2, or 3 mm or choose to run a manual calibration. Additionally, Asymmetric Cut-off can be enabled, which allows for a higher lift-off distance while keeping the landing distance low. The fifth tab, called "Power," includes all settings related to power-saving. One can 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. In Low Power mode, the DeathAdder V2 Pro merely lowers the maximum PCS of the Focus+ from 650 IPS (16.51 m/s) to 480 IPS (12.19 m/s), which is still very high. According to Razer, power consumption will be reduced by about 40% in Low Power mode, which extends battery life accordingly. Low Power mode should not be confused with the low power warning blink at 5% battery life, which is not user-configurable. 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, the software had a RAM footprint of 370 MB on average when running in the foreground, which doesn't change when minimized, be it to the taskbar or the system tray. Upon exiting the application, several processes with an overall RAM footprint of 180 MB keep running. Remarkably, these processes even load when setting Synapse not to auto-start with Windows. The only way to shut off everything while having Synapse installed is by running the firmware updater for the DeathAdder V2 Pro.

Lighting

The DeathAdder V2 Pro has but a single lighting zone, which is the logo. 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 can be adjusted as well. More advanced effects can be created using Chroma Studio. 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 modes:

Battery Life

According to Razer, expected battery life sits at up to 70 hours in 2.4 GHz mode and up to 120 hours in Bluetooth mode. Razer claims these figures with the mouse in constant motion and illumination disabled, at the highest applicable polling rate for each mode; i.e., 1000 Hz for 2.4 GHz and 133 Hz for Bluetooth. I've used the DeathAdder V2 Pro with illumination enabled and a polling rate of 1000 Hz for five hours, which resulted in a remaining battery level of 90%. Assuming a linear consumption rate, this would result in an expected battery life of about 50 hours with illumination enabled. Thus, we can conclude that Razer's numbers are likely accurate. Furthermore, one can extend battery life significantly by setting "Low Power Mode" to 100%, which doesn't affect performance in any meaningful way anyway. Razer states the battery to have a capacity of 450 mAh.

Using the included USB Type-A to Micro-USB charging cable, I've also measured the charging speed of the DeathAdder V2 Pro during the constant current (bulk) stage to be around 0.255 A.
