Just a tip for you guys running finders. I run a 7 as well and yes it is hard on power. If you havent turn down the brightness on your screen and you will be amazed the increase in battery time. Just like your cell or a tablet bright screens suck the battery pretty quick. I know on mine I crank it up in the sun then if I move inside I forget to turn it down sometimes even though I dont need it that bright on the inside.
