That is a good start.

I have gotten a fairly good improvement in system life by installing the
'speedfreq' package[1], which sets the SpeedStep state depending on the
CPU load.

My machine is now in 'powersave' almost all the time, and my battery
life is up substantially.

Other packages such as 'cpudyn' address the same issue.
