Luckily I have an iPad and 100% is 10 hours of battery life anyways, I doubt it would be killed so dramatically to only last 1 hour on a full charge. I can see a minimum of 5 hours before it dies completely and needs a new one. Also, just a question. Can u get an iPad battery replaced? Also, how does an HD get fried? iPad uses flash memory, so is it possible to damage that and lose everything too?
