I also have 2015 paperwhite, and 3 days ago I charged it from 0 (where it was for few months, which isnt healthy for battery at all) to 46%, and today I finished a book with 34% left. I only used backlight for about two hours, the rest was with backlight off. First half of book was with wifi on, before I realized that (I tend to keep it in airplane mode whenever possible for battery savings, dictionaries work offline too)
