问题
Is there a way to get the instant power consumption on an Android phone? Not a per process consumption, but an overall consumption.
I need it to be accessible on an app to be associated with some settings on the phone at that time.
Regarding the access of the information from an app, is it possible to get the PowerTutor data into my own app?

As commented by @adelphus, some devices have current info on /sys fs. There is a lot of comments about CurrentWidget code, available here. The link may guide your search to especific files.
