An article posted on the always-useful MacFixIt.com shows Apple confirming that certain system processes can shorten battery run times according to a Knowledge Base document posted on Apple’s web site.
The document confirms that “runaway” processes (or those that use much larger amounts of CPU time than seem to be necessary) can dramatically reduce battery life on Apple laptops such as the iBook, PowerBook, MacBook and MacBook Pro.
Per the document: “Battery runtimes can be reduced if an application(s) has runaway or taken over system processes. This can cause the processor to work overtime and consume unnecessary battery power. [...]
and:
“If any process is taking more than 70% of the CPU [...] verify if the process is needed. If not, quit the process by selecting the process and clicking the Quit button in the upper left corner of the window to regain CPU process control. This can lead to longer battery runtime.”
Practical advice and never be afraid of the Activity Monitor program, for it is your friend, despite residing in the slightly-intimidating Utilities folder.
