GSam is showing Apps as using 84% of battery with kernel and Android OS being the worse culprits. The Kernel is using 30% and OS about 12%. Screen on time is 1h 10 mins and there's 45 minutes of wakelocks. I've turned off pretty much all background synching including emails and facebook notifications, disabled Google Now etc. I'm wondering if a hard reset might help? Or have I just got a faulty unit?
What radios do you have on? (WiFi, Bluetooth, GPS, LTE)
If you have LTE on, are you in an LTE area?
What is your phone signal like in your area? (Poor signal severely drains the battery)
You should definitely be getting better battery life with that amount of usage. Try the App Wakelock Detector to catch an app that may be keeping your phone awake and draining the battery a little.
