Brand new Pixel 5A, Android 12 latest update (October 2021), both Location (all the time) and Bluetooth allowed/enabled.
App usage shows Hamagen is responsible for 17% of total usage - almost twice as much as Youtube which I watched for hours!
If it's any consolation, "Haramzor" is pretty bad too with 8% (about the same as YouTube with the usage mentioned above)...
For comparison, Life360 which I have enabled and is monitoring my location (all the time), physical activity, and nearby devices took only 2% over the same time period.
