Software

The Aria XD7 comes with its own lightweight software. All options are accessible through three different tabs. The first page allows for button remapping to mouse, keyboard, media, and macro functions, along with the ability to adjust debounce time, which effectively controls click latency, at a range of 0 to 30 ms in increments of 1. Profile management is present as well. The second page houses CPI adjustment settings for up to seven color-coded levels, ranging from 50 to 26,000 CPI in increments of 50. Values can be put in directly by double-clicking the value instead of using the slider. Any non-native values are truncated to native ones. Also included are the usual Windows pointer settings, along with polling rate (125/250/500/1000 Hz), LOD (1/2 mm), and angle snapping (on/off) adjustment options. "Ripple control" is disabled by default, but can be enabled to apply smoothing, which lessens jitter at higher CPI steps at the cost of increased motion delay. A macro editor can be found on the third page.

All settings changes are saved to the on-board memory, so the software does not need to be running (or even installed) all the time. On my system, the software had a RAM footprint of 20 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

Fantech states a maximum battery life of 27 hours when using 2.4 GHz at a polling rate of 1000 Hz, and 54 hours using Bluetooth at the maximum applicable polling rate, which is host-controlled and typically 133 Hz. While the software includes a battery level indicator, it is highly inaccurate, with the value changing essentially at random. This is expected, as the Aria XD7 lacks a fuel gauge IC. Accordingly, I'm unable to gauge anything. For the record, the indicator still showed 100% after 8 hours of continuous use.

By default, the mouse enters a sleep state after exactly one minute of inactivity, which shuts the CPI indicator LED off as well.

Using the included USB Type-A to Type-C charging cable, I also measured the charging speed during the constant current stage, excluding the additional current expended for the charging light flashing. When the mouse is lifted, 0.300 A can be measured, which drops to 0.266 A when not lifted. The battery has a capacity of 300 mAh.
