Every wonder why you don't lose you phone list and other info when you change batteries?You are going to need to explain that one to me.
It is not a lot of power, but there is small storage of power.
Enough power to maintain the "Creepy" info, that is part of this Post.
My point was... the only thing that STOPS cellular connection is the LACK of your Sim Card.
I accidentally left my phone on and the battery went "dead". It would not start, connect, or wake up the screen [todays iStuff shuts down to protect from this]. It finally showed a BATT screen at 3% and didn't link up until 10%.
Guess what, I didn't lose any list, messages, or programmed info.

I was a Ham Operator. RF emissions alone can power small thing.Cite your assertions.
Have you ever seen a "no battery perpetual motion" clock? I have. It uses RF antenna reception to power it.
