Hopefully not.

Have you put a lot of books on it recently? The number of books does affect performance, but it shouldn't be noticeable until you get into the thousands of books.

These could be the symptoms of a corrupt database on the device. If you have powered off and on and had some books reloaded as new or lost the reading status of some other books, then it is probably a corrupt database. Or if you use calibre, my Kobo Utilities plugin can check the database state. Or you can use any SQLite database management to do this.

If it is a corrupt database, logging out of your Kobo account on the device and back in will generate an new database and then reload your books. If that doesn't fix it, you might need to do a factory reset. Hopefully it won't come to that.
