Alright. I have an HTC One running Paranoid Android 4.4.2 Beta 2 (just switched from CM 11 to test it out), and my phone has, 3 times now since I got it completely set up, gotten VERY hot (hotter than it does when I play Galaxy on Fire 2) and dropped about 10% battery in less than a minute.
I have XPosed installed and I use Greenify to make sure nothing can keep my device wakelocked. I can make a list of applications I have installed if that will help. I keep location services off, GPS off,use the standard Google keyboard and default Paranoid Android launcher.
A list of what I have installed:
