Either by voltage or by time? Preferrably by voltage. Is this possible with WP?

This would be nice. There are no metrics in WP to give much feedback.

I was wondering the same thing myself the other day. It would be handy to take the guesswork out of pegging the guilty App(s).

Although not technically impossible, it is impossible at the moment. MS could possibly create a list (apps couldn't do this, as it would require direct OS support) showing how often specific apps accessed which functions (WiFi, LTE, each CPU core, every co-processor on the SoC, screen-time, etc), but many of those components have variable power requirements, so that wouldn't really give you what you want. It won't happen any time soon unfortunately.
