Started with overclocking yesterday, with hilarious results.

Background info: back in PR 1.1.1, I had an issue where the CPU would lock at 50%+ usage with no apps open. I managed to avoid the problem by eliminating practically all widgets.

Anyway, I read a few threads, jakiman's excellent guide and started with the 'ideal' profile with limits = [250, 1100].

The results were GREAT! I could finally watch Youtube, and basically any video site with absolutely no jerkiness or lag. The whole system became much more responsive and fluid.

I tested stability by about 35 minutes of non-stop web video watching. Not shockingly, this drained the battery by 15% or so, and the phone heated up (don't have the temperature module yet, but it was quite warm to the touch).

Coincidentally, I had installed the excellent 'Desktop Activity' app, and euphoric, I created a Widget Heaven profile (pretty much all the widgets that would fit in 4 screens). Satisfied with the layout, I reverted to my original desktop layout and left the phone idle. At this point, the remaining battery was 75%.

I came back to a drained phone: BatteryGraph showed the 50% CPU bug, and the steepest linear drop I've ever seen - and this must be some sort of record: the phone went through 75% of the battery in 2 hours.

My next settings to test: Starving at 1000Mhz.
