You wouldn't get the tech-savvy people with that, no. But it's easy to imagine someone barely making it through a day, not quite cottoning on, but hearing how Android phones last longer - and dismissing reports about iPhones lasting longer because their iPhone... doesn't. They're not replacing their phones over this, but for their next phone they're choosing an Android. For battery reasons. Fastforward 2-3 years and most of these folks are switching (with renewal of subscription). My main question regarding such a scenario: could they find the right balance, ie. drain the battery enough to annoy, but not so much as to attract investigation that'll definitively identify facebook's app as the culprit? That I doubt.
