Those figures are not in any way comparable.

My ebook reader is on for a couple of hours a day, and gets charged maybe once every two or three weeks. (Including the odd week-end in standby, when I forget to turn it off.)
An e-reader uses very little power except for the brief time intervals when the screen is refreshed. If you use it to read books or documents, actual battery life is measured in whole days. Of course this is true only if you keep the wireless network off!
(Tablets, on the contrary, require significant power just to keep the screen backlight on, and tend to have much faster -and power hungry- processors.)
So: yes, those figures are comparable.
