I've read through the iPad battery recommendations from apple. http://www.apple.com/batteries/ipad.html Besides the recommended monthly full charge cycle routine, is it best to use my iPad until the battery is lower, say 20% then recharge or just recharge when its not being used? (90% 96% 82% or whatever). I have a tendency to plug it in every time I'm not using it thus my obsession with battery 100%. I tend to stockpile items from Sam's Club, too.
