4.4.2 update and battery life fix
I know this subject comes up in a variety of topics and it's really hard to sort the wood from the chaff.
So my "cool story bro" is that I had massively poor battery life following KitKat upgrade and have tried many of those battery saver/greenify apps with no resultant improvement.
I bit the bullet and did a factory reset after I had backed up everything with Kies.
End result is battery life is back to normal today.
