That's a great test! The only nuance worth mentioning is most cases that a faraday bag would be needed for a cell phone, it would need to ensure everything was cut out completely. This is more difficult to test due to light waves' ability to transmit electromagnetic signals. So it would basically need to have no access to external light of any type, which nulls these as useful, but only by themselves and only in situations where complete cut isolation from any signal is needed. This is probably why it was said not to work as a faraday bag.
Cheers. A way to test the quality of a static bag. Just what I needed. I'm sure someone will say it's not an accurate way to test, but it's fine for my purposes.
True say, anti static just means it won't create it's own static charge. But it can't protect from outside charges unlike this faraday bag. I even was confused on what was what till I decided to look into it.
The grey bag you have is “static dissipative” this is the best type of bag to protect sensitive electronics from ESD damage. This bag is slightly conductive across its entire material with conductive doping. Pink anti static bags are polyethylene and they will not create a charge on their own when rubbed together or pulled apart (or at least too minimal to matter). However they are not conductive. In electronics manufacturing you will commonly see a combination of the pink bags and the metallic bags. The pink polyethylene can be used to make bubble wrap to safely protect the electronics in shipping while they are inside of the metallic static-dissipative bag. Any electronics stored in static dissipative bags should be opened up in a static safe environment like an ESD safe mat which is also static dissipative as well as connected to earth ground through a resistor. Aluminum foil would work even better for what you are trying to achieve. Except you can’t read the screen. However aluminum foil is conductive but it wouldn’t be considered static Dissipative. A charge across aluminum foil would be a dead short if you put an IC chip on aluminum foil it would short out if any static charge was on it at a rate that is uncontrolled and would cause too much current through the chip which could damage it. however on a static dissipative bag it’s actually a controlled resistance with the way the plastic is doped so that the charge applied to the chip would be dissipated at a slower rate which is a lot safer for the IC than aluminum Foil or copper foil or some kind of dead short.

If anything it would at least help you catch fake ones.
Thank you for testing!
The bag used in your testing is actually a faraday shield. A pink anti-static bag is not.

Good valid test!
That bag seems thicker then some of the other ones tho that I have seen
Nested bags will give you a better result :)
great video! But i think you need a anti-static mat ! 😀
What is the name of the wifi analyzer program on your phone?
If I recall properly it was literally called wifi analyzer lol
