Telecom Anon here. It's not as black and white as "you can track a powered down/battery dead phone".
>Different phones do different things.
>Some even track GPS data while off and then upload to carrier once they are back on.
>Phones do not keep their LTE or 5G radios on while powered off, their is software on the SoC that runs before Android or IOS that abso-fucking-lutely can decide to do this from a HW point of view but I've never heard any reasonable accusation that this possibility is used anywhere(yet?).

> Phones absolutely have a Hibernate (where they still make GSM checks with location data) and an "off" mode where they don't, and all the operating systems purposefully disguise these. Still usually not keeping on LTE or 5G as it takes too much power.
> If your phone has pegasus on it, I'd wager it can not be truly shutdown by anything but an absolute 0v coming out of the battery.
> High chance we all have pegasus on our phones

TL;DR
>Turning your phone is not a guarantee that you're not being tracked.
>A turned off phone is not guaranteeably trackable.
>If you wanna be an assassin you need a clean phone per mission anyway
>Removing the battery while the phone is on is a safe chance you're not being tracked but in theory some resistors still have power in them for a time. Could it power on GPS yeah probably, but could it power on anything to transmit out? I doubt it.
