My 1st gen IPad (WiFi, 32GB), doesn't get even close to the stated 10hrs of battery life. I have followed the recommended guidelines of waiting until battery is fully depleted, before charging, but still get no more than about five hours of usage from my unit. I don't believe I have had this thing for a full month yet, but long enough (I think) for the battery to have developed a healthy charging cycle.
I would also like to add that I am not into movies, or other media files being played on my iPad. The most I do on it is surf the web, and handle my emailings. Shouldn't the battery last longer than what I am getting from it, especially with the manner in which I use it?
I would like to know how others are maki out with their battery consumption issues.
