I certainly would not make that assumption. This gets to the heart of
Ms. Hackborn's comment: per-component power measurement is tricky
business without low-level hardware data collection (e.g., Qualcomm
MDP). It's all just guesswork. Chipsets vary in power consumption,
sometimes fairly widely, let alone differences in CPU and GPU.

That's odd. Trepn Profiler is built into the MDP firmware -- it isn't
something you run on the development desktop or something. But, yes,
the MDP is crazy expensive.
