I'd at least look into WiFi settings and turn Always Allow Scanning to Off. Then maybe look at your GPS settings and try the battery friendly mode or GPS only mode. I also don't allow Google to use your WiFi for better location results. There have been similar bugs reported with 4.4 here is some info and afew people trying to squash the issue on a Nexus
You boys need root!
I'm not sure if any of the wake lock apps out can show you what's causing this without root but maybe look into it.

Also you can try changing the "keep WiFi on during sleep" to either off or only when plugged in. That may help. Just suggestions that's all. Maybe something here will help somebody.

Thank you for those tips! I didn't know about that wifi one. I immediately unchecked always scanning. I keep my wifi on to make sure I use wifi, if available, but I don't need it always scanning. I hesitated on the gps switch, but I figured I'll try it on power saver and see what happens.


After turning off wifi scanning, that's what I got. That looks better to me. Although my usage time is lower than my previous screenshot, I started my day at 90% (forgot to charge last night, and that's as high as I could get it before leaving for work), and I'm using my phone more today.
