I have a Kindle classic. The battery life is very good when I am at our normal residence near Detroit. It will last for days between charges (even though I typically keep it fully charged). However, when I am at our vacation home (camper in Caseville Michigan) the Kindle battery drains very quickly. I am assuming this is do to a weak reception in the area. I end up shutting off Whispersync. Does anyone else experience this? Just wondering if it is typical. Thanks Jerry
