On-device Settings

Compared to their previous wired releases, VAXEE has added several new settings on the XE Wireless, which are accessed by certain button combinations. There are three buttons for CPI, polling rate, and button debounce time. By holding each of them for three seconds while the mouse is powered off and then switching to powered on, MotionSync (on/off), lift-off distance (low/high), and High-Speed Mode (on/off) can be adjusted as well. Note that this is only possible if the mouse is not plugged in for charging.

Battery Life

VAXEE states a maximum battery life of 90 hours when using the default run mode and 45 hours when using High-Speed Mode, at a polling rate of 1000 Hz for each. Furthermore, an expected battery life of 50 hours is cited when using the so-called competitive firmware. As the XE Wireless lacks software, one could assume that checking the battery charge status is impossible, but that is not the case. Instead, by pressing the function button, the current charge status will be displayed through two LEDs at the top, with two lights signifying 100-61% charge, the upper light 60-21%, lower light 20-10%, and the lower light blinking a charge of less than 10%. Of course, this isn't granular enough to gauge anything, but at least gives one an idea of when charging may be needed. For the record, after 10 hours of continuous use at 1000 Hz, I only ever got to see the first charging stage.

Using the included USB Type-A to Type-C charging cable, I also measured the charging speed during the constant current stage. When lifted, 0.340 A can be measured, which drops to 0.326 A when not lifted. The battery has a capacity of 400 mAh.
