b. Do Faraday bags damage cell phones?
Dead or did it just turn itself off since there were no signals?

Your phone lost comms with your carrier. The alphabets have programmed it to shut down when that happens?
It might have increased its transmit power since it couldn’t receive any tower signals, and so it killed its battery much quicker than normal.
Incidentally you can test the effectiveness of a Faraday bag by putting your phone into it and then calling it from another phone. If your phone rings then it’s still in touch with the local cell tower, which means the bag isn’t completely blocking signals.
It wasn’t the Faraday bag...most likely, the phone killed the battery by constantly searching for cell towers. You should put it in airplane mode when you put it in the bag.
It suffocated..........................
Also, you don’t really need a Faraday bag. Just put your phone inside the microwave.
Since it’s to block phone, turn your phone off, then place in bag. Self diagnostics of your operating system may go nuts if inside the bag and phone is on
.
Do they make whole-house faraday bags?
You have created a microwave oven putting a cell phone that is ON in a faraday bag. I am surprised it works after.
Put your phone into “Airplane Mode” before putting it in the Faraday bag. Then it won’t drain out its power looking for a signal.
A well functioning Faraday cage will sever communications between phone and tower. As long as the device is turned on it will continue to seek an active access point until it either finds one or exhausts its battery.
I shut my devices down before sealing in the cage.
Turn the phone off first. I have in the past wrapped mine in tinfoil which also works but I turn it off first. Never had a problem.
