“Of the many advanced technologies being introduced in OS X Mavericks, one of the most useful for Mac laptop users is Timer Coalescing,” Peter Cohen reports for iMore. “It’s an energy-saving technique that promises to extend battery life on your Mac laptop by forcing the laptop’s CPU into a low-power mode whenever it’s available.”
“In the space of a few seconds, your CPU will spike in activity many times,” Cohen reports. “This is not only because of the applications you’re running, but also because of all the other housekeeping tasks needed to keep OS X up and running. In between those moments, your Mac’s CPU enters an idle state, where it’s not doing much of anything.”
Cohen reports, “To wake from that idle state requires power, and using power means the battery of your MacBook Air or MacBook Pro won’t last as long. And right now, in Mountain Lion and earlier revisions of OS X, your Mac isn’t doing it as efficiently as it could be. That means power is getting wasted, and your Mac laptop is draining its battery faster than it has to… In its tests, Apple compared Mountain Lion and a development build of Mavericks running on a production MacBook Air. They discovered that Timer Coalescing can reduce CPU activity by 72 percent.”
