Chosen Solution
My iPhone 6 has a few areas of damage: the screen very slightly lifts up/clicks at the bottom, the metal on the bottom outside is kind of beaten up, and at one point water got under the screen. Phone functions perfectly. But wondering, does this damage mean the phone is emitting greater EMF than is standard? Used this phone during pregnancy.
If you look carefully enough, you’ll find material to read out there which claims almost anything. To determine the risk of ‘increased radiation’ from a dropped or damaged iPhone, one would first have to determine what types and levels of radiation the device created in the first place, and thus whether the casing or normal functioning of the device would actually put the user at risk in normal circumstances, let alone if the device was damaged in some way. It is kinda like a science experiment. :-) My answer would be that phones give off the same amount of radiation as they are when they are not damaged versus when they are damaged. It’s more of an urban legend that a damaged iPhone emits more radiation then an iPhone in perfect shape. Since there remains debate about whether cellphones actually pose a genuine health risk at all, all one could reasonably say is that you are not likely to be at any additional risk unless you also note a degraded performance from the iPhone.
To add to @ajcooke01 answer: The only method to protect your self from EMI would be to live is a Faraday Cage with no electronics! Clearly, thats just not possible.
While the image shows a high voltage spark, all radio & microwave signals would be blocked as well. So then that gets into the ability of the phone to gain access to these signals or send them if you were inside the Faraday cage (full cage). So now lets look at your phone internals you’ll see detail shields around some areas. Here the Orange chip is the modem which would be the most radio emissive part of your phones internals.
In your case the lifted edge wouldn’t really alter the emissions that much. If you have such a concern I would get the phone properly fixed. After you deliver your baby the risk to your baby being closer to your phone would be more of an issue. So make sure you place your mobile phone away (or fully off) from your baby even if you don’t fix it.
