Lif3 smartchip could reduce smartphone radiation by up to 95% - that is the claim by maker Cellsafe. And you know what? I cannot prove or disprove that statement.
Sorry for the negative inference – this could be the best thing to stop fried brains or kidneys but I cannot prove it. It all looks kosher and it claims to reduce radiation and has several test reports on the Australian site.
Essentially Lif3 is an A$69.95 laminated, .35mm thick “chip” (like an RFID chip), that attaches to the back of an Apple 5, 5S, SE, 6, 6S, and Plus, Samsung Galaxy S6, S7, an Edge versions (you must order the correct one) and there is a generic one for all other Android devices.
Cellsafe says the Smartchip incorporates an ultra-thin printed circuit board. This circuit board is configured for each device model and is then sprayed with several thin layers of microwave-absorbing material. They claim it does not affect reception – again I cannot prove or disprove that – it seemed fine giving the same signal bars before and after application.

I used it on a Samsung S7 Edge and it fit well inside the clear flip cover. It is no use if you use a metal cover or an expandable battery pack.
Whirlpool has a thread here and I will let you draw your own conclusions.
If you are serious about radiation, then do some more research – I cannot in all conscience recommend or criticise it.
