OK, it is Android then. You might look into the threads that discuss this issue. I’ll try to look back and find one (or more) and will add them here if I do.
IIRC one of the issues is the way to stop it is to shut down this on Android, but then other apps that need that location sharing are similarly affected so this could be an issue depending on how much you use/need them.
EDIT: Ah, yes, here’s the most recent one, but I think there are some other refs to it in earlier threads. This should give you enough search terms to find them: https://community.gotennamesh.com/t/android-battery-drain-how-to-properly-close-app-after-use/2333
