This words may not directly come up from Steve Jobs but he did mention that iPad with Flash will cut battery life from 10 hours to 1.5 hours. That works out to be 85% battery drain. However, since iPad will not have Flash, I think we are NOT going to find out if this will be the true measurement. In my opinion, whatever was stated is just a bit difficult to comprehend. Imagine, if you have a netbook that you used it to play Flash games or any Flash enabled application, will it drain your battery so dramatically?
