I love my Kindle 3G BUT the battery life is poor. Battery Life of Two Months - A single charge lasts up to two months with wireless off That's the claim direct from the Amazon Kindle 3G page. Mine lasts 2-3 days and I only get to read at bedtime, that's 2-3 hours a day max. I only have wireless on when I'm looking for a new book. What can I do?
