I sold the Kobo Mini to BookCat and can confirm that the battery appears to still be in great condition. I've never heavily used it to test the battery in that respect, as it was always a back-up ereader, but the battery retains its charge really well when not being used a lot. I also have a Sony 350 but the battery on it does run down. The battery on the Mini is the most impressive thing about it for me, that was why I though it might be good to pass on to someone who reads only occasionally. Like BookCat, if it had a frontlight, I'd happily have kept it.
