I disabled google plus and google search because they'd wake my phone up constantly despite disabling just about all sync and location items within them. Now I can leave the phone on standby 12 hours and come back with it at 96% instead of 65%. Don't need or want all that constant sync and location tracking stuff.
I can manually check for whatever I need myself as needed, which saves the battery from constantly monitoring for 'stuff' .. I have voice commands, etc. all OFF for now until I figure out what doesn't needlessly suck resources.
