Require More is not equal to Drain

IMHO that list is garbage. Many items appear more than once with different wording.
file size causes more draw

? Ok, given that the file may need to be read longer (more bytes), but whu is that different than the internal Flash

200 microamps is nothing when compared to a page flip processor usage.

That 200 microamps is probably 0 when the processor sleeps between pages.

WiFi and Backlights are the big draw. The former can be shut down. Don't have a Sony, so I don't know the power saving options available.
