… so it is not included in either the Kindle edition or the paperback edition of 
The Complete User’s Guide to the Amazing Amazon Kindle.
And I cannot promise that you will be able to replicate it in the privacy of your own home, but it may be worth a try.
It’s coming on a year now that I’ve had my first Kindle, and it had gotten a lot of wear — there have even been a few planned and unplanned “drop tests” along the way. With each passing month, I have to admit that its battery life between charges has grown more disappointing, and there have also been some (perhaps related) screen or keyboard freeze issues recently.
This weekend, on a whim, I swapped Kindle batteries between mine and my 10-year-old son Danny’s Kindle, which I purchased for him last May in appreciation for the fact that he came up with the idea for the lovely Northumberland tree photograph that I licensed and that has become the visual brand for my Kindle books.
Immediately following the battery swap, my Kindle began to work perfectly and its battery life seems to be living up to original product claims again! That’s not the surprising part. The surprising part is that Danny’s Kindle (with what I would heretofore have described as my old worn-out battery) is working perfectly too! I have no way of explaining this, but, for instance, I have left both Kindles powered up with the wireless switch “on” for over 24 hours, and both are showing over 50% power remaining on the battery indicator.
So, I realize, we do not all have 2 Kindles in our homes. And Amazon is out of Kindle batteries (yes, my theory is that it is the battery backlog that is causing the Kindle backlog), so it’s not like you can just order another 
Amazon Kindle Replacement Battery and get one this week.
But if your Kindle is being to perform in a slightly tired fashion and you have access to another Kindle, even a friend’s, it may be worth experimenting with a battery swap.
Meanwhile, I hope that some Kindle engineer from Area 126 or Area 51 or somewhere will comment or email me and shed light on this phenomenon, or suggest Kindle counseling for me.
