I've found that when I forget to force close this app after a ride, my iPad will completely drain of battery in a few hours even while asleep. I could understand if the device was open and the app was running, but it happens when the device is totally at rest.

It's kind of weird to me, because I've seen that if I ever have to minimize the app and use another one (like looking something up in a web browser), TPV will almost always totally close out and end my ride.
