I've posted a few threads since I received my Reader last Thursday, 10/9. I've had horrible battery life thus far. I don't know if it's the "breaking in period" or what. (I'm beginning to think it's the 'or what')
As I wrote in another thread about problems with the battery; today I used it primarily for reading. 3 hours then the battery was kaput! After some issues again, and some frantic discussion here

and on iRex forum, I was able to get it up and running (thought it was dead!).
Currently,
It has been on -
NOT USED, just on - for the last 4 hours. I am down to one bar.
4 bars lasted 15"
3 bars lasted 90"
2 bars lasted 100"
1 bar lasted .... I don't know yet, it's been going for 45" so far.
(I'll update the post tomorrow and give a final reading on how long it lasted.)
Given the times above, I do not see this Reader lasting any longer than 6 hours and again, that IS
NOT BEING USED. It is just sitting here on my desk while I work on my computer.
This cannot
possibly be normal. If so, as an expensive devise, this will not do. I easily spend 10-12+ hours reading journals and papers every day. If I have to carry the briefcase of papers with me as a 'backup', what good is this Reader?
That said, I think my Reader might have some problems that are not common with other owners of the DR1000S, which may be contributing to the very short battery life. Otherwise, I do enjoy using (what little I have) this Reader, and it is rather wonderful!
How is everyone else's battery life holding up?
