After researching this a little and watching some YouTube videos I discovered that removing the battery will most likely NOT get the job done. Because the GPS circuitry inside the phone is powered by another battery that you can't get to.
However, you can make your phone invisible by putting it in a mylar potato chip bag. The bag forms a "Faraday Cage" which prevents receiving and sending radio signals.
"Let the chips fall where they may ..."
It might also depend on the mill thickness of the mylar bag
I know that many electronic parts are shipped in mylar
Maybe a good time to 'recycle' some of those bags, and see if Apple or Google continues to send you updated location temps and time ?
