Hello!
You can Install KIES3 - Samsung's phone suite from here: http://www.samsung.com/sg/support/usefulsoftware/KIES/
and then check for updates!![]()
hi!! solved it last night by downloading the .TAR file for XSP 5.1.1 OJ6 firmware and flashed with Odin. simple and straightforward

i tried KIES but they said oh it's outdated now all change to smart switch, which i already have, but it refused to update my software.
anyway I think that "bad" battery life is most likely due to the LTE modem.. due to the Exynos SoC, Samsung is unable to use Qualcomm's LTE modems, thus using their in-house "Shannon" modem for networks.. which I suspect is why the battery drains quick when on bad LTE.
you can read up more about the Exynos 7420 on AnAndTech
