Count me in as one of the folks that had rapidly draining battery issues post-Kit Kat. Based on a tip in another thread, I went into Google Settings, Select "Search and Now", Select "Voice", Select "'OK Google' Detection", and de-select the box that says "From Google Search app" which will also grey out the options for "from any screen" and "from lock screen".
I am seeing HUGE battery performance from this tweak. And it makes sense as this was introduced in Kit Kat. If it works, and you want a better way to access Google Now voice search, download 'Home2 Shortcut' from the play store. Once downloaded, in Step 1, select "voice search"; leave Step 2 alone, In step 3, choose your launcher. Then press close. At the popup, select "Home 2 Shortcut" as the default HOME application. With this enables, one press of the Home button takes you to your home screen, and two quick presses of the Home button starts Google Now voice search.
Your options may vary, but I see a huge difference.
