I was "topping off" my battery the other night when the indicator showed it was only one-quarter or less down, and DH told me it would probably wear the battery out early by charging it unnecessarily, i.e. every night when it doesn't need it yet. Is this true?Trekker said:One thing to remember...these batteries have a certain amount of charge/discharge cycles before they degrade to the point of being unusable, so if you don't need whispernet, leave it off.
For example...let's say that the battery is good for 500 cycles (just throwing a number out there) - you can charge it once every 4 days, or you could charge it once every 14 days. Obviously it will last longer with a 14 day cycle.
Another thing is age...lithium polymer batteries degrade with age. I've read various things...some say after 2 years of sitting, they only retain 40% of their charging capacity.
Hopefully the batteries will last for the life of the Kindle....or at least until we all want the next model.
