If you're on a Mac and using OSX, I highly suggest checking out Turbo Boost switcher https://github.com/rugarciap/Turbo-Boost-Switcher https://github.com/rugarciap/Turbo-Boost-Switcher It's given me at least an hour more of battery life on my aging Macbook Pro 13 (2011). Another handy tool on OSX is CoconutBattery which is basically the closest I've found to PowerTop for monitoring power usage (I know ActivityMonitor somewhat shows power usage BUT it makes my fans & CPU spin like crazy when it's gathering info!)
