Parasitic draw with newer Toyota SOS/subscription (SPYWARE) service systems
Scotty,
I am suffering a parasitic draw with the new Toyota infospyware system. 52mA draw after 12 hours "asleep" and a dead battery in 3-4 days if my 2020 4Runner Off-Road is not driven, new Toyota replacement battery. I used Toyota's own service bulletin to test it. The dealer made up that it had an 11mA draw but wouldn't put it in writing. Have you seen this issue?
FYI - The system is on 100% of the time and is feeding GPS information even if there isn't a subscription for tracking.
An 11ma draw would not kill the battery in a few days. You might want to verify what's going on.
This step-by-step procedure for checking overall parasitic draw is for Nissan but the basic procedure would be the same on pretty much any vehicle:

If drawing over about 25ma (the spec varies with different models) there is a problem. You can measure the draw of each circuit to pinpoint the issue.

the new Toyota infospyware system.
I don't know what that is, but if it's on all the time then it's suspect.
52mA draw after 12 hours "asleep" and a dead battery in 3-4 day
52mA should not kill a battery in 4 days. It would take around 6 months. 50mA is basically two indicator LEDs worth of current which many people have on all the time.
However, that doesn't mean something isn't turning on or "turning up" when you're not around and using a lot more.
Diagnosis is simple. Disable it and see if the problem goes away. If it does, then it's either defective or a piece of crap.
Toyota has a protocol for parasitic draw, Toyota’s Quick Training Guide QT611B, with it.
I took the car into the dealership for this and other issues. It was sold TCUV (certified used). The dealership, after one year, is refunding my full purchase price. They had the car for a week with 6 main concerns and 3 minor ones (i.e. trim bolt in the rear gate). There were other issues with the battery, enough to exacerbate the situation.
Scotty always says "don't buy a former rental car." I knew this going into it, but it was TCUV. Scotty was right. I'm just lucky I documented everything with video, meter readings and pictures.
I am buying new next time...
