most likely you have apps that are doing lots of stuff in the
background, or indeed looping and crashing, which kills the battery.
it's almost always random apps that are at fault and not the OS itself.
un-install all your apps (your vendors crapware may not be un-installable -
see if you can disable it by Settings->Apps->All->click-on-app->Disable
instead) and check the battery life again.
and/or hook it up to adb, log on, and see what it's actually doing -
top, logcat, powertop, procrank, dumpsys activity processes, etc.
no phones are secure - android or not - I'm sure the .gov people who care
can always break in through the GSM layer via a fake tower and then up
to the OS 'cos it's all mmap'd. if you carry a smart phone you are
carrying a pretty tracking and surveillance device.

would complain about is a slightly over-sensitive screen.
Sony officially supports unlocking so you can run cyanogenmod on it if
you want. maybe you lose some accelerated camera function when you
unlock it - I forget. warranty too, obviously (unless you re-lock it
before returning), but that's true of any unlockable phone.
I left mine locked and run a rooted stock image. Sony was really quick
about releasing 4.4.4, and it has little bundled crapware and some nice
features, so I feel no real need to install cyanogenmod just yet.
battery life is ~5 days for me - or more precisely about 6 hours of
screen-on time. mostly web browsing & email, wifi on only when the
screen is on, mobile data on rarely. I prefer to see updates only when
I feel like checking it rather than have the thing chirp at me 24x7.
so that's quite a low power use configuration choice - your battery life
will probably be shorter. the Z1 is the same SoC as Z1 Ultra, but other
things vary (battery, screen size, camera) so that will affect your
battery life too.
BTW, it's crazy, but the Sony bootloader only cryptographically
verifies that the kernel is stock - so as long as you stick to the
stock kernel you can flash a rooted /data image and it's perfectly
if you choose rooted stock rather than unlock & CM, then the procedure is
(of course) a little convoluted - you have to revert to an old rootable
OS version, root it using your favourite kernel bug tool (may be written by
Russians but some even come with src, or just write your own), and install
a custom recovery (dual CWM and TWRP) so that you can then do backups
of all partitions and flash the image of your choice. it's not hard to
do once you wade through days of (of course) conflicting XDA posts.
if you get one then let me know and I'll give you the cheat sheet.
