at first i thought it was just waze. i drove in to work, killed the app from the task switcher, but it it continued to drain battery throughout the day to the point where it was in the red by the drive home. closed everything in the app switcher, plugged it in, and waze battery usage continued to climb. reset the phone. waze usage continued climbing. eventually i simply deleted waze. used google maps instead for a couple days without issue, but barely a week later the same thing has started happening with google maps. which leads me to believe this is an OS issue with background processes not properly getting killed. has anyone else encountered this? what am i to do? do i have to delete and reinstall mapping apps each time i use them? ps. before anyone suggests apple maps, a) thats a non-solution to say that we can't choose 3rd party apps anymore, and b) apple maps has broken bluetooth support with my car, and i find the traffic information pretty terrible compared to others.
