I am talking about the app that shows up as "Google Search" in the Battery statistics.
My Phone is a Nexus 4 on KitKat.
This app draws a lot of battery, up to 50% in idle standby. It also has a "Keep awake" value of usually at least several hours.
Possibly related, I noticed that my phone is ALWAYS awake according to the battery stats. One charge merely lasts 8 hours.
I have switched off Location Recognition and I have deactivated the Hotword Detection ("Ok Google") in the Settings for the google search bar on my home screen.
Does anyone experience the same problem and are there any suggestions for a solution?
EDIT: Disabling the search app solves the always awake issue and improves battery life. Of course this is not a real fix.
