I can help.
Here is what I am at today. (See attached pics).
For non rooted phones:
1. Go to settings>privacy and disable backup
2. Use Easy Battery Saver under intelligent mode. I like it better than Juice Defender.
It will disable the radio and Wi-Fi when the screen is off but still check for new messages. LTE is a battery killer. I'm mainly on HSPA.
For rooted phones:
Do 1 and 2
3. Freeze the following apps that constantly run in background (using Titanium Backup pro):
Wifi Sharing manager (used for kies air and not tethering)
Both Social Hub processes.
