Amazon.com really knows how to treat its customers.
Although I've read a few dozen books on my Kindle by now, my use of it is erratic. I use it heavily for days or weeks at a time, then set it aside for a while to address the stack of paper books by my nightstand. (When Montalvo Systems shut down, I had two 2.5-foot stacks of unread books. After a long summer of unemployment, the unread stack is down to a mere five titles.)
Last Tuesday, I found an e-book I wanted to read, so I got out the Kindle and saw it was dead. (The battery lasts only a few days even if I'm not using it, which really isn't good enough.) I charged it overnight and moved the book onto the Kindle on Wednesday. Later that day when I wanted to read the book, I found the Kindle was out of juice already.
I charged it overnight again (with the radio off in case it was having some kind of issue), forgot about it Thursday and remembered it this morning. But it was dead again. I started it charging again before going out to a lunch interview. When I returned, I turned the unit on and just sort of kept an eye on it, pressing buttons occasionally to keep it mostly awake while doing some other work on my computer.
The battery ran down in less than two hours.
