I was using the Cinch app from the app store to resize windows. It causes Finders energy impact to be around 60 while its open and brings battery life time down to 3 hours on my 2011 MBP 15".
If you want similar functionality to cinch a app called hyperdock does the same thing but without the bug. my battery life is back to normal and finder energy impact is down to 0 when not in use now and barley goes over 10 when in use.
