Well it's something, but obviusly u haven't read about how to report bugs.
Heating issue when? On idle, playing, or just browsing? I don't have any heating issue, on these sessions. Rapid charge works for me, but if your screen is on while charge it can be a heat and slow charge issue too.
It can be an app, it can be because u didn't do a clean flash, but we don't know anything about it because u don't tell how, and what u did, and when happens what happens. Taking logcat could be useful the developer too.
I'm on PE+ since the first + build, only bug I've found is the screencast and sometimes the videos doesn't start on instagram or face etc.
With latest build my idle drain is 0,38%/h - 1,3 %/h.
I'm not a developer but I know what information they need to fix problems if it's common
