Most books I read these days are 800+ pages and if I spend most of Sunday reading, my pw1 needs charging on Monday as the battery bar is really thin. But pw1 charges up super fast. It's 100% within like 20 minutes.
Thanks.

The battery life feels much like the PW1 for me, perhaps a little longer: I'm discharging the internal battery about once every day and a half, and recharging the whole thing more or less weekly. Given the higher resolution of the screen and the extra power needed to drive it, that's pretty impressive. Given that battery tech hadn't done anything magical since the PW1 came out, Amazon's claims of months of battery life were always laughable.
Now when the things in the lab now for batteries with massive nanostructured surface area that charge in seconds, and batteries with gloop on them that let them charge hundreds of thousands of times without degradation come out, *that* will be a change -- but still, I don't expect to see actual months of battery life from a Kindle even then. That would be an order of magnitude higher energy density and in the end you have to consider that you're carrying what is basically a bomb around. I see nothing in the rumblings from the battery tech world that suggests that any such jump is even on the horizon. So we'll still have charge-it-every-week but it might charge in a minute and a half and charge from its cover in ten seconds or something.
the limiting factor then becomes the amount of power the thing can pull out of a domestic power supply without blowing a fuse!
(The internal battery capacity doesn't really factor into this because when you charge that up you're not tethered to anything, and it takes so little time that it happens when you're walking somewhere or making lunch: spend half an hour on something, including reading, and oh it's charged again.)
