You can also try disabling volte if you didn't already (that may help with high cell standby usage), but 6h SOT I have to admit is a nice score, cpu has less stuff to do without all that bloatware. I'm assuming you use wifi only?

Yes, I am mostly using WiFi (both at work and home) and have 4G/LTE just when driving or going out, but that's much less than WiFi usage. And I don't use Facebook so this will help battery life as well as I understood that FB is a high battery drain factor. My usage consists of browsing (Dolphin Browser), whatsapp, viber, skype, e-mail, Tapatalk, Word, ocazional navigation, camera... No listening to music, no movies
