I think you are referring to this study: http://blog.opower.com/2012/09/how-much-does-it-cost-to-char...

Which has the iPhone 5 at $0.41/y, the Samsung S III at $0.53/y and the iPad (model unclear, but I guess the 3), at $1.36.

I agree with your point though: the electricity cost of these devices is already negligible, an e-ink display wouldn’t make much of a difference.
