Software

For the StormBreaker Max CF, Pwnage has moved towards a web driver. Much like other web driver solutions, this one connects through WebHID and therefore will, at least as of now, only work on Chromium-based browsers such as Chrome, Edge, and Opera (desktop). As of now, the macro editor is not yet functional, though everything else works without any issues.

All options are presented across three pages. Polling rate may be set to 125, 250, 500, 1000, 2000, 4000, or 8000 Hz. Furthermore, "Sleep Time" defines the idle time needed to pass before the mouse enters sleep mode, and may be set to 30 seconds, one minute, five minutes, or a custom value. On the second page, CPI adjustment is possible for up to five color-coded levels, ranging from 50 to 36,000 CPI in increments of 50 CPI, and either uniformly or separately for the x- and y-axis. Values may be entered manually, but regardless of using manual input or the slider, any non-native values aren't truncated to native ones. "MotionSync" can be turned on or off, which turning on synchronizes SPI reads with USB polls at the cost of a motion delay penalty of up to an entire polling interval. Lift-off distance may be set to 0.7, 1, or 2 mm. Button remapping is possible to mouse, keyboard, and media, functions. Lastly, profile management is present, too.

Battery Life

Pwnage cites a battery life of up to 90 hours presumably at 1000 Hz ("gaming"), and 160 hours at 125 Hz ("office"). The software includes a percentage-based battery life indicator with single-digit accuracy, which appears to be accurate and reliable. For every two hours of continuous use at 8000 Hz, the indicator went down by 5%, which would translate to an expected battery life of 40 hours at that polling rate. Further testing showed that for each hour of use at 1000 Hz, the indicator went down by 1%. Conceivably, these numbers cannot be true at the same time, which is why I'm inclined to consider the 1000 Hz figure the correct one, and would estimate around 20–25 hours of battery life at 8000 Hz.

By default, the StormBreaker Max CF goes into sleep mode after five minutes of inactivity, though this can be adjusted in the software. Somewhat counterintuitively, waking from sleep requires clicking a button instead of motion.

Using the included USB Type-A to Type-C charging cable, I measured the charging speed during the constant current stage, which sits at 0.351 A when lifted and 0.336 A when not lifted. The battery has a capacity of 300 mAh (3.8 V) and utilizes a 3-pin JST connector.
