I'd say I probably get something like 25-30h reading time from my Voyage. That's with WiFi switched off (WiFi is the biggest battery drain after the screen). I typically read for 1-2h a day, and recharge my Voyage once every couple of weeks. The battery time is certainly such that it's something I never even think about.

The basic Kindle has much shorter battery life than any of the other models in the Kindle range. They seem to have gone for minimising the weight at the expense of battery life.
