Amazon Kindle Touch (4th Generation) D01200

Amazon Kindle Touch (4th Generation) D01200 - I’m not sure if it’s user error but there has been times where it seems like the battery was draining the first time I bought it, but I charged it a couple of weeks ago, and just picked it up again to list it, and battery still was charged up pretty good! - I tried and tried to deregister it but it always came up as error, so if bought, it will have to be deregistered and put into own account.
