But I have not tested to read continuously to see how long it lasts.
I've never stopped the time either, maybe my gutfeeling is totally wrong.
When reading, I have to power up again about twice per week. But maybe that's because I stress the battery by copying files and things like that.
For the moment, I'd just say I expect about the same duration as with the 6" readers.
