I have the step tracker turned off, Bluetooth is off as well. Why is it always on and running? Can't hibernate it. I still want to use the app but don't want it running 24/7, it eats the battery a little bit.
Go to <Settings> and see if anything is turned on in there - mine had <Detect Workouts> turned on - I am 67 years old, have an L4 - L5 disc fusion and damaged nerves... I'm not doing ANY workouts, so I DIDN'T turn that on! I'm sure that would keep the App running in the background. I just shut that off... take a look, might be something in there!
