So I decided I wanted to update my Kindle 4 (non-ad) to the latest firmware, but it was having issues, presumably due to the screensaver hack I put on it a few years ago (I'm 80% sure this was it, but i can't remember for certain

So I decided to do a factory reset, assuming it would clear out the hack, allowing me to update my Kindle. This didn't work however, and the hack is still obviously installed (tried setting up a screensavers folder again, and it worked). I wouldn't normally have an issues with this, however since doing this, my battery now drains extremely fast. I used to be able to go a couple of weeks before needing to charge it again, but now it drains after a couple of days, and takes longer to charge.
Anyone one know what the issue might be?
