On-device Settings

While the on-device configuration options on the Xlite V3 eS aren't as extensive as the software options present for the Xlite V3, all the important settings are there. Through dedicated buttons, CPI can be set to 400, 800, 1600, 3200, 6400, or 12,800, whereas polling rate can be set to 500, 1000, 2000, or 4000 Hz, with 8000 Hz being exclusive to wired operation. Through button combinations, one can also adjust debounce time (0, 3, 5, 7, 10, or 12 ms), lift-off distance (1 or 2 mm), and MotionSync (on/off), the latter of which synchronizes SPI reads with USB polls, at the cost of up to an entire interval of added motion delay. When pressing one of the two dedicated buttons, the OLED screen will first be turned on, and only then will any setting changes be possible.

Battery Life

Pulsar states a maximum battery life of up to 100 hours, though no details are given under which conditions. While the OLED display does feature a percentage-based battery life indicator seemingly featuring single-digit precision, its accuracy and reliability appears dubious, as even after two hours of use at 4000 Hz, it only went down by 1%. Assuming linear scaling, this would equate to an expected battery life of 200 hours at 4000 Hz, which of course is impossible. As such, gauging expected battery life is not possible.

After 40 seconds of inactivity, the mouse enters sleep mode, from which it can be woken up by moving the mouse, but not by clicking a main button.

Using the included USB Type-A to Type-C charging cable, I measured the charging speed during the constant current stage, which sits at around 0.264 A when lifted and 0.247 A when not lifted. The battery has a capacity of 500 mAh and utilizes a 3-pin JST connector.
