>>> Does charging the battery more than once a day eventually "kill" the battery...forever? I read somewhere that the battery life is approximately three years, with one daily complete charge, and decreases with multiple charges. I notice I'm having to charge the battery more than once a day, over the past year and a half.

>>> Charge Cycles
>>> A properly maintained iPad battery is designed to retain up to 80% of its original capacity at 1000 full charge and discharge cycles.

>> So, if you *completely* discharge your iPad's battery EVERY day, then recharge it, it should only have 80% of its original capacity left after 3 years.

> What about topping it off? I recharge almost every day but the battery isn't completely discharged. It's around 50% or a little more. I usually plug it in overnight.

I don't think it is on that page, but somewhere Apple states that two 50% discharge, then recharge, cycles are the equivalent of one 100% cycle.
