Significant Battery Drain after Yosemite Public Update

I'm experiencing significant battery drain after updating to Yosemite Beta 6 that did not go away with the public update. Yesterday, Mid-2012 MBP lost 30% while in standby for about an hour. I've attached EtreCheck report here. Could someone please advise how to optimize to improve battery life? Additionally, do you think it will be possible to experience the 6+ hrs battery life I had pre-Yosemite? Thanks in advance. Your help is greatly appreciated!

Problem description:

Battery Drain after Updating to Yosemite Public Release (14A389). Problem initially detected after updating to Beta 6. Battery drains 1-2% every few mins with no apps using significant data.

[Note: As I type, Chrome is reportedly using significant energy despite only ONE tab being open— an apple forum thread about this Yosemite battery drain— and Two enabled extensions that are not in use (Hangouts & Evernote Web Clipper.]

Typing this description has resulted in a 3% decrease in battery life.
