yesh 
I got a simple fix for you, no need root or anything, just
follow my next few set of instructions.
First thing I need to do is to confirm the drain is due to your
phone not sleeping.
Go play store, search "cpu spy" download, install, run, and
check duration for deep sleep, and 200mhz.
I'll let you know what to do after the above you check for me
please. Thank you.
