I've had no problems with my PaperWhite as far as refreshing the page and it has a very good battery life. When Kindle ereader batteries are too low a message pops up to remind the user to recharge so it's hard to forget. And I have yet to have my PaperWhite go dead (due to low battery) even though it's over a year old. Of course it can't read epubs but that's what Calibre is for.
