Here's a summary:
Yes your phone can track you even when it's turned off.
Blue Tooth Low Energy (BLE) was integrated into the Bluetooth 4.0 specification in December 2009. When you turn off your phone, this chip stays powered on so you can still find your phone.
Apple and Amazon are the primary utilizers of this technology (not sure about Google, but probably them too)
The "Find my phone" feature and Apple Air tags use BLE to accompish this. But it can be used for much much more.
BLE can be used to form a mesh network, communicating with other BLE enabled devices from TV's IoT devices, the list goes on.
The idea is that over a mesh network, a device can send location and other tracking data until a participating device that is connected to the internet is found, where the data can then be forwarded to Apple HQ
So yeah your phone or Alexa could be reporting you neighbors location, who they're with and thier conversations to Apple or Amazon
If they were to employ triangulation using other BLE devices, they can get your location more accurately to within centimetres.
Devices can be turned into slaves, observers or peripherals to carry out or pass on instructions to the target device which could then turn the device on / off, then turn the camera on or off, record stuff, you name it.
