One final aspect of the performance to note is battery life. Amazon rates the new Kindle Paperwhite for up to 10 weeks of battery on a full charge. I only had the device for a little less than a week, so it was not possible for me to fully verify that. With that in mind, though, the battery drained by a mere 10 percent or so in that time frame. Maybe you won't get 10 weeks out of it if you read for hours every day, but it'll last a good, long while no matter how you shake it.
