When I opened my Sony Reader on Dec. 24 (early xmas present
, I charged it fully, loaded some books, and then began playing with it unpluged. I have probably done about 1000 "page turns." I am estimating the number of "page turns" by including:
1. Actual page turns in a book
2. Approximate number of times turn on and off (each counting "1 page turn")
3. Approximate number of times I've switched the page to view the menu or to set a bookmark.
I have not charged it since Dec. 24 and just today, I got the "low battery" warning. This seems short of the 7000+ sony stated. I assume this is because the battery drains over time and that it takes a few charges to reach peak power storage. I would also assume it uses some power to remember which book you are reading since it turns on with the last page viewed. I should also note that I use an SD card, which may use up more power to access?
