Show HN: Individual App Power Usage Tracking on Mac in Native Swift
macbookbatterymonitor.com
I built this app to solve a problem for myself, my m1 max would regularly run out of battery in 2 hours lately while coding at a cafe. I could never work out what apps were causing the egregious battery life performance, activity monitor wasn't particularly useful.
So I built a power attribution engine with the native apple silicon power readings. Its not perfect, currently it can attribute CPU + Ram usage to the apps, on top of reporting in real time your total watt draw (like stats) and the cpu, gpu, display and usb power draw.
I would appreciate some feedback, and any suggestions for improvements! I am working on adding GPU attribution and power limiting as while low power mode is handy I think it would be awesome to be able to set a specific W limit for your apps/device.
Cheers, Ryan
