tl;dr: I’m looking for something like AccuBattery, but for Linux
What do you use to measure laptop battery life in Linux?
I can easily get a momentary estimate of battery life. But this fluctuates based on load, screen backlight etc.
I’m looking for something that will collect my usage patterns over time - load, #processes, screen backlight, … - and allow me to predict remaining runtime more accurately.
I’d love for the data to be parsable, so that I can analyze it myself and e.g. find the “worst offenders” - processes affecting battery runtime the most.
Thank you for any tips!
If you’re technically inclined, a simple bash script with a for loop could dump the time and discharge rate to a text file every minute. Then you could copy/paste that into LibreOffice calc and do yourself some pretty graphs, or whatever.
edit: just found a tool called powerstat which looks like it does sampling over longer intervals.
sudo apt install powerstatInteresting, hadn’t heard of
powerstat. I’ll be checking that, thanks!
