I factory reset a second time and have only installed the absolute bare essentials. Today the issue has gone. My suspicion is location services but I will reinstall more apps slowly until I prove this.

Please do share your result, I really don't want to root my phone and also installed too many apps to do a factory re-set without knowing it will definitely work.
DEVICES:
CURRENT: Moto G
PAST DEVICE: Samsung S4 i9505 <- HTC Sensation <- HTC Desire | a lot of non-smart phone

I installed more apps last night and battery life is still stellar. My current suspicion is a combination of the BBC Weather app with Location mode set to High accuracy.

25% Google Play services, 14% Android system...
I disabled Google Now only and the battery draining has been normalized. I will try to enable it again.

I have exactly the same issue - since going to 4.4.2. Battery usage was great in 4.3 - but since going to 4.4 it was awful (android system using 30% of the battery overnight).

I did a factory reset - which kept me at 4.4 but uninstalled all my apps etc (and put google play services back to the original version). I then turned off location services altogether (I had tried battery saver, but it made no difference). Since then I have been having little or no issues - android system is hardly using thing overnight. Google play services has updated back to the latest version.

So it is defo to do with location services and/or some app using it to death - haven't risked turning it back on yet - but will do - might go for gps only first, then battery saver (which did no good last time). Google now is currently off - but I may turn it back on as part of my testing

Disabled location, now Android System only uses 13% of the battery instead of 35%. Still this is way too high for whatever it is used for, will keep investigating.
