Still wouldn't do nothing except waste battery power.
I had all kinds of older phones, and in older times 20-25 years ago there were tons of places with zero signal (villages, islands, places out of the city, national parks, and so on) and the phones survived just fine.
That's as zero as in a faraday cage, as far as the phone is concerned -- no tower to talk to at all, 0 bars for hours or days on end.
Yes, I meant a dead battery. The "solution" I was replying to was suggesting keeping your phone in a Faraday cage to thwart government surveillance, presumably a small portable cage that you would take with you wherever you go. If you leave your phone running in there, there's a pretty good chance that the battery will be dead when you take it out to use it, which defeats the entire purpose of carrying a phone in the first place.
