Software

The M3 comes with its own lightweight software. All settings are distributed across five different tabs. The first tab includes button remapping, allowing one to rebind all buttons to mouse, keyboard, media, or macro functions. The second tab contains CPI adjustment at a range from 100–26,000 CPI in increments of 50, for up to five color-coded levels. CPI values can be entered manually, and upon confirmation any non-native values are automatically truncated to the next native value. Furthermore, polling rate can be set to 125, 500, or 1000 Hz. The third tab has a macro editor. On the fourth page, Windows pointer settings along with various other settings are present. Lift-off distance can be set to either low or high. Furthermore, "Ripple" can be enabled or disabled, which introduces smoothing at higher CPI levels in order to lessen jitter at the cost of added motion delay. Likewise, if enabled, "MotionSync" lowers SPI timing jitter at the cost of increased motion delay, by up to an entire polling interval. "Angle snapping" may be enabled or disabled. "Debounce time" effectively controls click latency, with lower values decreasing latency but increasing the likelihood of eventual double-clicking and so-called slam clicking. The selection ranges from 0 to 20 ms and can be adjusted in increments of 1, with 8 ms being the default. Finally, a so-called "E-sports mode" is present, whose purpose is unclear. The fifth tab features miscellaneous software configuration options. Lastly, profile management is available, too.

All setting changes are saved live 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 18 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, all processes are terminated, as they should be.

Battery Life

Darmoshark states a maximum battery life of up to 83 hours, though no details are provided regarding polling rate or connectivity. The software indicates a battery life indicator with seemingly single-digit accuracy, which appears to be largely accurate and reliable. After six hours of continuous use at 1000 Hz in 2.4 GHz operation, the indicator showed 89% charge. Assuming linear consumption, an estimated battery life of around 60 hours therefore could be expected. In addition to the software battery indicator, the scroll wheel will light up in a corresponding color upon being turned on.

By default, the mouse enters a sleep state after exactly one minute of inactivity, from which it can be woken by either pressing a button or moving the mouse.

Using the included USB Type-A to Type-C charging cable, I measured the charging speed during the constant current stage. When lifted, 0.296 A can be measured, which drops to 0.272 A when not lifted. The battery has a capacity of 500 mAh.
