The youtube video applet definitely doesn't stop doing things when the 
video is finished playing; say, on my laptop the video when playing is 
about 21% and the animations when finished peak around 14% with 2% when 
static.

Well, having written most of the Maemo article ;), Wikipedia isn't the
place for that sort of insane detail. The Maemo article is less for
people who already know a thing or two about Maemo than it is for
people that know absolutely nothing about it.

I reckon this is because there's some Javascript chundering away in the 
background on whatever page you've got loaded. I had a similar problem when I 
added a news-ticker to my Beermad site. Because I have a local copy of the site 
running on my N800, the news-ticker ran all night after I'd finished using the 
tablet. Or at least for as much of the night as it took to run the battery down.

I don't think this is a bug in the browser as such, more a side-effect of the 
CPU used by Javascript on a device with limited battery life. The only answer I 
could see on the browser side might be if it stopped running embedded 
Javascript when the device was locked (or perhaps when the display had timed 
out). But then other people might have a reason why they need it to keep on 
running.
