For those following along at home, can you quote what issue or subissues you’re referencing? This is a general linux battery tuning thread so I think this is primarily a collection of best practices/discussion of workarounds, I don’t think there’s any single resolution expected for this thread.
I think the biggest known remaining battery issues are non-Linux specific:
- higher-than-average battery drain in suspend, exacerbated by attached USB device expansion cards (Windows generally gets around this by hibernating automatically at 5% battery usage and in Linux you can do something similar with suspend-and-hibernate; I wrote a simple tool to track battery drain in suspend btw).
- potential RTC boot issues if left off and unplugged for an extended period of time (weeks)
Each of these problems has their own threads and hopefully updates go there (or in this thread that was gathering known issues).
