I have an old Kindle with keyboard. It charges up OK, green light comes on, but the charge only lasts about 2-3 days of just reading for a half hour at night. What suggestions?
try a reboot by holding the power on for a full 30 seconds
ceck to see if you have a book stuck indexing by searching for a nonsense word like pmfj and making sure to select the Search Everywhere option
Replace the battery - dead easy, and costs about £10 - £15 . Youtube will show you how, but a small phillips screwdriver and a guitar pick are pretty much all you need
My K3G is now on its third new battery
I have to totally disagree with @Projectionist.
If your kindle is working, albeit a little less economically than it used to, then follow any advice that tells you to check software and downloads and things (such as suggested by poster @CBR.
No Kindle has been designed to be maintained by owners and trying to open up a kindle is just as likely to break it as to mend it.
I totally respect that @Projectionist claims to have managed to do it, but I, for one, would rather put up with charging a bit more regularly than sit there looking at a broken and useless device :(

If your Kindle uses any form of USB cable to charge, why not consider getting a small power bank and, if needed, a longer cable so you can charge it while you're using it without sacrificing too much portability?
