If you guys want to turn around your battery life, upgrade to kitkat. We can try to play hide and seek all day with what drains your battery, the fact is, i got better battery drain with GPS, Localization, Wifi, BT and NFC all on, on kit kat, then you guys have with all that shut off on Jelly Bean, and then upgrade to X-Note 9.0
P.S. Please explain how you were running 4.2 when the phone came stock with 4.3?
