Yes, of course, the percentile indicator is just a reference. Sometimes it takes a little more or less to discharge. I´ve been reading quite a few hours lately, turning it off and on, and after the third day I had 80%... As in any conservation scheme, the less you turn it on or off, smaller print and wider margins (to avoid too rapid page changes) help conserve battery. Keep wifi on, glow on minimum necessary, and enjoy.
I have to say that glowlight eats up a huge amount of energy. But charging it every 15 days or so is much better than any tablet!
