Tin Foil your Phone!There are quite a few smartphone cases, Faraday bags, and other little gizmos out there that claim to protect you from the phones RF waves.

A common method that people use is to line one (or both) sides of their phone case with good old aluminum foil.

So, the question is: Does tin foiling your phone really work? How much? And where exactly should you put the foil?

Watch to find out!

Let’s take a look:

Note that while the foil will reflect some of the RF energy away from your body, it isn’t 100% protection.

Radio wave propagation is an entire science in and of itself… In short, it’s complicated!

Also note that you could increase the protection by using several layers of foil separated by packing tape or some other non-conductive material (like plastic).

You could also use copper tape, which would perform a BIT better. But as always, the best protection is to just TURN IT OFF when you’re not using it!

    Nice test. Never knew the transmit power was so asymmetrical between the screen side and the back.

    Early on you could remove the battery from your phone and be sure it was not usable. Then they got smart and removed battery access capability. Why? Speculation is that the Deep State has the ability to “wake up” your phone if needed even when turned off. I would not discount that theory.

    A good Faraday cage is the best. Any old box with a tight fitting lid will do. Line it with copper tape and it should do just fine. Save yourself a couple of hundred bucks on a meter and test your box by turning your Blue Tooth on, closing the box lid, and checking to see if it will connect with other Blue Tooth devices placed right outside the Faraday box.

    Check this out. A phone designed for super low sar values. Would love to see a review of this. Finally some “innovation”?
