Created attachment 275743 [details] Export from Sysinfo GUI app Percentage battery power left depletes rapidly with regular use of the PC. This issue does not occur on such a scale in Windows, leaving me to believe this is an issue with something in Linux using too many resources.

Could you please use powertop to track which components are the offenders? And also please provide the turbostat/top/perf record to check the activity of the system?
