The background processes constantly use between 1% and 3% CPU, even when the GUI application isn't running. It's coming from both logioptionsplusupdater.exe and logioptionsplusagent.exe. Other background tasks and background services don't use this much CPU. Although 2% isn't a ton, this can drain battery life unnecessarily. If I sort my task manager "Details" pane by CPU time, those two .exe files are consistently at the top of the CPU time usage right behind System Idle Process.
