Just to follow up.
Uninstalled Kernel Power using the Nokia Kernel .desktop icon.
3 Hours later fairly normal service resumes (normally average 400-500 wakes) , device is cool again.
How odd.

Code:
$ sudo powertop
Powertop 1.13.3
status: Unknown job: pmtrackerdaemon
Sleeping for 11 seconds before sampling
Collecting data for 30 seconds
Sample interval was 00m 30s 91311us
