I wouldn't trust a foil bag to do anything 100%.
the only 100% way to not be caught is not bring it.
it also provides an alibi. "see, my phone was here all day long."
I'm talking about an actual faraday bag, not a foil bag. That, combined with a powered off device keeps you fairly protected. They aren't going to get into your phone if it's powered off.
There's going to be a deviation in usage regardless, it's not providing an alibi. A gap of time when you're not using your device that you normally would be is a marker they look for. They key is keeping them locked out (again, power them off).
I mean, a proper Faraday cage will block anything unless the US government has figured out how to break the laws of physics...
A proper Faraday cage, a truly excellent one, just the most Faraday of all the cages, is easily defeated by physical attacks such as getting your phone cloned when you get mass arrested and summarily released on OR.
Faraday cage does not prevent gyroscopes and accelerometers from working. Then if you remove it from a faraday cage in the future, it will transmit all that movement
Since you're posting this all over the thread, I'll also have to repeat the information that gyro/accelerometers are not capable of doing that. Small measurement errors stack up and throw it completely off.
Without GPS or tower based error correction any location prediction based on conservation of momentum in the phone will be useless before very long if the phone is moving.
Sounds theoretically possible I guess...
