why do you think both android and ios always trying to keep BT turned on?
For android, location services doesn't work properly without Bluetooth on, so that could be related
I know BT will help location services, I am not sure what you mean will not work properly?
It won't pin location quick enough?
Iirc, precise location queries don't return values without the BT radio enabled. Works the other way too, the app needs location permission to discover bt devices in proximity and location must be enabled at the system level.

Android and ios use completely different methods. For example, they listen to frequencies that are inaudible to us and, for example, TV advertising plays an inaudible sound as a trigger for Android/IOs in addition to the audible sound. To impose targeted advertising in order to allocate devices even without a network, etc. They wouldn't actually need backdoors as they get more than enough information as it is. But I don't want to imply that I don't expect backdoors there, because this has been proven in any case and often enough.
