Will not loading some startup items save battery?

Message #1 - Posted 2004/02/13 - Tim Murray

If I have a need to do everything I can to converve battery power in a standalone situation (i.e., not connected to anything at all), will I save a few milliwatts by not loading some startup items I know I won't be using? Candidates include cron, IPServices, LDAP, mDSNresponder, Network, NetInfo, NetworkExtensions, Samba, and so on? Thanks.

I have also posted a related question regarding learning more about startup items, in "Like to learn more about startup items".

With careful manipulation of these startup items, you might conceivably extend battery life by ten seconds or so, if you're lucky. Most of the startup items are system daemons which sit in the background and literally do nothing at all until such time as they're asked. If you're doing any work which needs the daemon (and will therefore ask it to do something), then not having the daemon running will reduce your ability to actually use the computer. If you're not doing any such work, the daemon's just going to sit there inactive, using no CPU time.
