I recently traded my 1st owner '11 Edge Limited for a '19 ST, I can tell you that the power points behave differently between the 2.
The '11 Power points did not turn off, I had an Escort radar detector that stayed plugged in at all times and would power itself down after some time but that was the detector, there was power to the port always.
I also had a voltage readout in the lighter plug and a BT OBDII device always plugged in, These did not seem to make a noticeable impact on the battery.
The '19 shuts off the power point after a few minutes.
