Could be a mix of all other apps i have i suppose. I have incepted, and run fastern9 with it, Dunno if thats a problem or not, but there is no problem with the app in it self. Its just when idling my phone with it running background/forground it makes my n9 very warm and it empties battery within a couple of hours.

Is there a app for messuring power usage? Or a command in terminal that gives an hint. For all i know it could be something else reacting to opera and not opera reacting with something else. I have something called energy profiler , from meecatalog but that only give me how much current its use with everything.
