Unless I’m using the wrong terms in my search it really seems like there’s no tool for Linux that can tell me what processes used the most CPU (typically this has a high correlation with energy usage) in the last hour or 24 hours.
Basically I want something like the Android battery usage app but for Linux.
Any system monitor app (and basically every DE has one) will show you the cpu usage. Check out Mission Center . It’s almost a carbon copy of windows’ task manager.
I have Mission Center. It’s great but at the process level it only shows current usage, not a time series average or summation.
