Thanks for asking. I keep it running in the background regularly and get 12 hrs easily and 15hrs normal with my iPhone 5 ... Compared to something like navigation which drains it in ~4 hrs. So the extra battery drain will not be a deal breaker for many ... but it still might be for some.... Totally depends on the user's situation in my opinion.
