Will removing the battery make the phone untraceable?
Assuming there’s no capacitors or capacitor capability, the last known location of the phone will be where you removed a battery with at least a partial charge.
IOW, if you have collection of old phones, like the one I retired last year, it would have pinged until the battery died (any capacitor would have run out eventually, too).
Capacitors (as I understand it) gave us “instant-on” TV where they didn’t “warm up” - storing energy. This is why it was dangerous to work inside an unplugged instant-on TV. Capacitors were also a way for storing energy for shooting electric-based power. I heard of satellite applications.
I’m sure we have people more articulate in this category here if they can add comments.
