Software

The DeathAdder V3 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 four 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 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. "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 fourth 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 402 MB on average when running in the foreground, which doesn't change when minimized, be it to the taskbar or system tray. Upon exiting the application, several processes with an overall RAM footprint of 210 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.

Battery Life

Razer states a maximum battery life of up to 90 hours. This refers to continuous usage at a polling rate of 1000 Hz. The software includes a percentage-based battery life indicator with single-digit accuracy, which is in fact reliable and accurate. For each five hours of use, the battery indicator went down by 6%. Hence, we can assume that expected battery life may in fact be very close to the cited figure.

After not moving the mouse for a short period, the DeathAdder V3 Pro enters a rest state from which it can be woken up by moving the mouse, but not by clicking a button. The same goes for sleep mode, which is entered after a certain amount of time set in minutes from 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 0.158 A. The battery has a capacity of 300 mAh.
