I think I may have an idea what is going on here. From what I have heard, the biggest thing that is taking away from the battery here is cortana. But why? I don't know if you guys noticed, but within the first day or two of using her, she asks you "is this your home?" and "is this where you work?". How did she know where you were? Fortuna CONSTANLTLY pings the GPS when you first set her up. I think Cortland is by far the biggest thing that is killing all of our batteries. So what is the solution? I think the best thing to do is to give it a few days. I think that when she finally gets the idea, she will calm down and stop pinging the GPS so much once she knows what your routine looks like. Let me know what you guys think of this.
