Given that list, yes, I would assume that the CPU is a significant (and most probably the single largest) proportion of power usage. If I'm wrong, then where is the power being used? Neither the screen nor the flash should be using any power "between page turns". I would doubt if the (very small) amount of volatile memory would account for all the power drain all on its lonesome. And finally, I doubt if the circuit-board itself would draw much power, without any of the components connected to it being active. |
As I said in my previous post, by far the biggest user of power is the screen (when you turn the page). The amount of power used by the CPU when it's in its low-power sleep mode is very small indeed.
