Software

The StormBreaker comes with its own lightweight software. All options are distributed across three different tabs. The first tab has button remapping to mouse, keyboard, media, and macro functions. The second page includes CPI adjustment for eight color-coded levels in increments of 50 at a range of 50–26,000 CPI. Any value containing whole numbers can be entered through the slider or box, and any non-native values will be truncated to native ones. Furthermore, polling rate (125, 250, 500, 1000, 2000 or 4000 Hz), lift-off distance (1/2 mm), and MotionSync (on/off) may be adjusted. "Sleep Mode" adjusts the idle time after which the mouse enters sleep mode, though I am unsure whether this actually has any effect. An additional setting called "slam-click prevention" is present, enabling which applies approximately 25 ms of defer-type debounce on the first click with either main button after lift-off. Lastly, a macro editor and profile management are present, too.

All settings changes are saved to the on-board memory, so the software does not need to be running all the time. On my system, the software had a RAM footprint of 20 to 32 MB on average when running in the foreground, which doesn't change when minimized to the system tray. Upon exiting the application, all processes are terminated, as they should be.

Battery Life

Pwnage provides two different battery life numbers: 120 hours for "office" usage, and 60 hours for "gaming" usage. Of course, it is entirely unclear what "office" and "gaming" actually entails, so these descriptions are essentially meaningless, and polling rate is not indicated, either. The percentage-based battery life indicator seemingly features single-digit accuracy, but the percentage varies greatly, so its accuracy is limited. Still, it is reliable enough to at least give a rough estimate. At a polling rate of 4000 Hz, for every hour of continuous usage, the indicator would go down by roughly 10%, suggesting an expected battery life of around 10 hours. This figure would translate to about 20 hours at 2000 Hz.

Using the included USB Type-A to Type-C charging cable, I also measured the charging speed during the constant current stage, which sits at around 0.556 A. This is in excess of USB specifications. The battery has a capacity of 300 mAh (3.8 V) and utilizes a 3-pin JST connector.
