from that same article:
Isn't this normal behavior (for the camera?) eg. throttle up when needed, throttle down when not?
It very much is. It looks like only the camera app can do that at this point in time. So we have the Benchmark app and the Camera App(in spurts). This is neither good nor bad, it simply is. Now, as long as all of that is known while ranking the "Fastest Cell Phone" and write up and comparison between phones, I see no real problem with it.
