Software

The M800 Pro Highspeed comes with its own lightweight software. All options are distributed across several pages. The first page has button remapping for all but the left main button to mouse, keyboard, media, and macro functions. The second page houses CPI adjustment settings for five color-coded levels, ranging from 100 to 26,000 CPI in increments of 100 CPI, despite the sensor supporting increments of 50 CPI. In wired mode, polling rate can be set 500, 1000, 2000 or 8000 Hz, whereas in wireless mode, 250, 500, 1000, or 2000 Hz may be selected. "Key Debounce Delay" denotes debounce time and can be set to 4, 8, 15, or 20 ms, with higher values lowering the odds of inadvertent double-clicking but increasing click latency. Lift-off distance may be set to 1 or 2 mm. Lastly, a macro editor and profile management are present as well.

After applying, all setting changes are 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 46 MB on average, along with some CPU usage, which doesn't change when minimized to the system tray. Upon exiting the application, all processes are terminated, as they should be.

Battery Life

Depending on the source, DELUX states a maximum battery life of up to 70 or 80 hours, though no details are provided regarding polling rate or connectivity. The battery life indicator within the software can only be described as unreliable and inaccurate, as even after close to 10 hours of use at 2000 and 1000 Hz, the percentage continued to sit at 97%. Accordingly, gauging anything is impossible.

After roughly two minutes of inactivity, the mouse enters a sleep state.

Using the included USB Type-A to Type-C charging cable, I measured the charging speed during the constant current stage, which sits at 0.273 A. The battery has a capacity of 500 mAh (3.7 V) and utilizes a 3-pin JST connector.
