Software
The OGM Cloud comes with its own lightweight software, which is compatible with both the OGM Pro and OGM Cloud. Hence, one first has to select "OGM Cloud" in the little drop-down menu in the right corner on the home tab before the settings will work properly.
All options 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 to 26,000 CPI in increments of 50, for up to seven 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, 250, 500, or 1000 Hz, with 2000 and 4000 Hz becoming available in conjunction with the 4K dongle. 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 1 or 2 mm. 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. My testing suggests that this setting is not functional. 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. Finally, a so-called "High-speed mode" is present, which changes the sensor run mode to corded mode, which only takes effect in 2.4 GHz mode at 125, 250, 500, or 1000 Hz, as both wired mode and polling rates of 2000 and 4000 Hz already default to corded mode. 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 29 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
Waizowl cites up to 80 hours of battery life at 1000 Hz, likely with High-speed mode disabled. The software includes a percentage-based battery life indicator with seemingly single-digit precision, but its accuracy and reliability are strictly limited. In my testing, even after three hours of continuous use at 4000 Hz, the indicator only went down by 1%, which is impossible; yet, when using the mouse at 1000 Hz with High-speed mode enabled, it went down by 6%. Reconciling these numbers is not possible, which is why I'm unable to gauge anything.
Sleep mode is entered after 5 minutes of inactivity by default, but can be adjusted within the software.
Using the included USB Type-A to Type-C charging cable, I measured the charging speed during the constant current stage, which sits around 0.151 A when lifted and 0.136 A when not lifted. The battery has a capacity of 300 mAh (3.7 V) and utilizes a 3-pin JST connector.
