I recently had major issues with my battery life, as in it wouldn't hold a charge for much more than 45 minutes to an hour during reading. I called CS and they asked which version I was in. When I checked, I was still in 2.3 so he gave me the link to upgrade to 2.3.3. Believe it or not, that was all it took to correct the issue-I'm back up to around 10 days of battery life on one charge!
