  • Reduce desktop effects (System->Preferences->Appearance->Visual Effects->None). even its has been has stated that enabling or disabling desktop effects generally has no impact on battery consumption (, we think that to much desktop effect will disturb your work and GPU will need more power consumption.
  • Use Hibernate rather than suspend power features. (System->Preferences->Power Management->On Battery Power).
  • Turning off a bunch of services that you don't need, and unloading their kernel drivers. See how to do it here.
