[LINK] mobile tracking

[Jim Birch]

If a phone can wake itself up it isn't really off.  Something is ticking
over.  It may have some components shutdown.

If the phone has been hacked it would be possible to get it to wake up
without visible sign.  However, I doubt that the makers would dare risking
this themselves.  People might get rather upset to find that their phone is
phoning home when they thought they have switched it off.  If phone was
trying to communicate when supposedly off someone would notice.

Removing an iPhone battery requires a screwdriver to open the case.  You
need to ignore the "Authorised Service Provider Only" message.

Most other phones allow users to remove or swap the battery.
