Good, Bad & Ugly --- My T Mobile Note 3 Battery Life

[logoseternal]

Hello guys.. I know there are already threads about Note 3 battery life, but being a newbie to android (previous iPhone owner), I just wanted to get your expert opinions about whether or not battery life of my T-mobile Note 3 is Good, Bad, or Ugly. Below are my settings now:

1. no notifications on except Kakao Talk (Korean social message app), Lookout, Twitter, Visual Voicemail,
2. background sync on (I know this drains power, but I like getting my emails by auto sync)
3. switching to wifi when wifi is available
4. brightness set to about 35% (no auto)
5. don't have SD card
6. don't use GPS often
7. voice control-incoming call on
8. Air view pen- speed dial preview & icon label on
9. air command on
10. motion- direct call on
11. location service off
12. using GSAM battery & Wakelock Detector
13. I usually charge my phone when it gets to about 10-15%
14. screen timeout to 1 minute

Please see below for GSAM monitor and battery report







What I do not understand is battery report says 6hours 33minutes 3 seconds but GSam says 12hours 36minutes. Which is right?
And Android system is draining most power; is there a way to fix that?

Thank you alll
