Topic Suggestion

One Line Summary

after getting all the pm patches into your system, there is a lot more work to do to get good battery life.

Abstract

The difference between PM enabled and a PM tuned device is about 4 days of standby battery life. Going the last mile on the PM tuning is really hard work, and has a lot of challenges you wouldn’t expect.

like device fw bugs, c-state and p-state issues, and generally involves a lot of tracing work in kernel and with power measurement hardware.
