Signal Causing Headache from 16 Pro off or on

My 16 Pro is emitting a signal of some kind that cannot be contained in a Faraday bag, aluminum or microwave oven that is turned off. When I placed the phone in the microwave it stopped the time and it hasn’t been right since. At the Apple Store and Apple on the phone all that was done was a diagnostic test. Can anyone suggest a way of stopping or preventing the signal from coming through while the phone is off or on?

iPhone 16 Pro, iOS 27

I’m sorry you’re experiencing headaches. What you’ve described doesn’t establish that a signal from the iPhone is causing them, or that the phone caused the microwave’s clock problem. Continuing symptoms while the phone is enclosed are not a measurement of a signal passing through the enclosure.


Please don’t put the phone in a microwave, even for testing, the risk is that someone could accidentally turn it on. Metal objects inside an operating microwave can cause arcing and damage.


For recurring or persistent headaches, please seek medical advice rather than relying on additional shielding experiments. The symptoms deserve attention, but research has not established low level electromagnetic exposure as the cause of symptoms attributed to “electromagnetic hypersensitivity.”


Headaches do not establish that a phone’s radio emissions caused them. World Health Organization and Australia’s radiation protection authority distinguish between genuine, sometimes disabling symptoms and the proposed electromagnetic cause. Scientific evidence has not established that low level electromagnetic exposure causes these reported symptoms. Medical assessment is appropriate. So, rather than dismissing the symptoms or assuming their cause you should discuss the headaches with trained medical professionals. No one here has the medical training or proper test equipment to prove or disprove your suspicions. A medical professional will. E your best resource at this point.

I was already at the Columbia, Maryland Genius Bar last Friday, with Dylan. He did the diagnostic on my phone and could only tell me it needed backing up. Which I did before I left. He further suggested I can call Apple, as they are not equipped to go any further with my phone. I called Apple and spoke with Donna this Friday afternoon. She ran the same diagnostic test on my phone and stated she couldn’t find anything wrong with it. She further stated that when you shut down the device it is off completely. I told her it couldn’t be due to the Find My feature. Donna stated that she was the final person I could get support from regarding this issue. I asked, was there an Apple community to get support from and she said no. When I came out of our meeting I saw the Apple community along with other Apple support. So I clicked on it to join. If there is another person in this community who can give me support, I would appreciate it! Thank you!

OK. I, along with most of the senior members on this forum who are posting to you are extremely doubtful your phone is the root cause of headaches. But then we are all typing to you from our sofas and none that I'm aware of are medical doctors. So I can't imagine you're going to get this solved here, nor evidently with Apple, since they could find nothing wrong with your phone in person or remotely.

Thanks for your reply, they don’t have the technology or equipment. Their fixes are tailored to specific areas in the phone ant the store or over the phone. Apparently the phone is not shut off completely even when FIND MY is shut off. I’m certain if Apple wanted to do a genuine deep dive into these devices, then there would be no need changing them out or purchasing new ones. The Bug Fix for this issue is to test the phones for the possibility of transmitting whether on or off any harmful transmissions of any kind.

Whatever is causing your issues, a solution is not going to be found by posting here. We've told you this is a user to user only forum. There's nothing anyone here can do to diagnose or stop whatever is causing headaches in any way. Telling us what you think Apple should be doing isn't going to get you anything here either. And I remain convinced that if this was an issue Apple needs to address, it would need to be one which affects many many many other users, but it clearly isn't doing that.

Dear Apple, you are aware the phone can be used as described by me. Whether off or one. You also know the techs at the store and over the phone cannot detect this. Your device is behaving in a manner that is not its intended use. Please fix the bug.
Apple is not reading here in this user-to-user forum.

It doesn't seem to matter how many times we try to explain this is a user to user only forum. They just want to complain and waste their time. I won't be responding further to them as that's just wasting my time.

Oh, I know. I have a complex document to finish editing, and I'm procrastinating. No one should ever have to do what are essentially spreadsheets in Word tables.

Sorry. I no longer have to worry about spreadsheets of any kind. Just welcome a customer to the store, take their credit card and send them home with something nice for their home!

RAM (Random Access Memory) does require electrical power to hold data and clears completely when the iPhone shuts down.


But Flash Storage retains all files, preferences, system state settings, etc for an indefinite amount of time without power.


That's why the iPhone retains its settings when power is removed completely from the iPhone. Example.....an old battery (or a dead battery) is removed and replaced with a new battery.
