2013-03-05 Forcibly drain your cellphone battery

If you want to forcibly drain your iPhone battery for some reason, first configure the display. Turn off the auto-lock, set the auto-brightness off and manually turn up the brightness to 100%.

Then go and warm up that little CPU by running a JavaScript benchmark, either with SunSpider if it's already pretty empty. Or go ahead and release the Kraken, which is a heavier test.
