IPhone Flash prototype got 30 min battery life

I don't know what you have running on your Macbook, but I have two Macbooks, one new and one about 2 years old, and my kids watch hours of Flash videos and Flash games until I have to wrestle the computer out of their hands because it is bedtime.

This "30 minute battery life" smells fishy. It is a friend of friend of a friend who woke up one day in his hotel room with his kidney removed and his iPhone battery drained.

I loaded up this classic video in Safari:

and watched the resource use. While the video was playing, the minimum CPU use from Safari was 48%, with frequent spikes above 60%. As soon as I closed the tab, CPU use dropped to about 2% and stayed there. On a laptop with a full charge and power-management profiles to optimize usage you can get away with this; on a power-constrained mobile device you most certainly can't.
