I know if you have had any other Galaxy phones (especially S3), you probably know about a battery draining issue with "gsiff_daemon" that also makes the phone hot!
Well, I got it!!!
I have a N900W8 Telcel with 4.4.2 rooted via CF Root with Knox 0x0.
I think that it was tripped by Battery Calibration by Nema...
Saw that renaming the file could correct the problem, and I did it. Still need to see if it is gone.
Just a heads up.
Anyone know hoy to completely remove this problem?
