This makes me wonder if your old Kindle was also doing the same thing and you didn't notice it. Constant re-indexing will obviously lead to severe battery drain because it works all the time, even when the Kindle is asleep.Tatiana said:
My guess would be that there is one of your books which is faulty in some way and is causing the indexing process to crash spectacularly. You probably need to find that book and delete it or get a new copy.
Which of the 935 books is it, I hear you ask?


If all else fails you may have to do a "binary search" approach - remove all the books, then add the first half. If it is OK then, you know the problem is in the second half, so add half of those and try again, when it fails you know the troublesome book is in the last batch you added, so remove them and then add only half of them and so on.
A pain, I know, but I don't know how else to pin it down. Other people may have better ideas - or may even say I'm talking rubbish, it has been known!
