During my studies on computer devices I noticed an extremely anomalous behavior regarding my iPhone, I hadn't tried an iPhone for many years and so I was curious to find out what updates were applied, I'm not a fan of Apple, so it was just to try since I've always had android and I happily continue with android devices.
In short when I left the iphone completely off and not in standby, it was actually off, checking the devices connected to the network from the control panel of my router I noticed that the wifi of the iphone was active and not only had it automatically connected to my router despite it being completely off, behavior that I had never seen in any mobile or desktop device.
Thinking it was a bug in the router I brought an EMF detector closer to the device and in fact it gave a positive result.
For android devices even just putting them in airplane mode the device did not emit any radio signal, and bringing the EMF detector closer gave a negative result.
An EMF detector (Electromagnetic Field Detector) is a device designed to measure the presence and strength of electromagnetic fields. These fields are generated by electrical power sources and electronic devices, such as power lines, electronic equipment, cell phones, computers, and wireless devices.
However, I am aware that it can generate false positives, for example the detector could produce false positives due to Faraday's law of induction, if you approach for example an EMF detector device on a smartphone that is in airplane mode, the electrical signals of the internal electronics even if the device is in standby would automatically produce a weak magnetic field that could be detected, however it would still be too weak to easily produce false positives, so I think this hypothesis can be discarded.
Personally I think that using proprietary, closed and non-open-source devices of this type is no longer safe and that espionage (in my opinion) could increase as we move forward with technology, furthermore if I turn off a smartphone I cannot remove the battery, with the old models it was possible, I'm not saying that perhaps the reasons are necessarily linked to espionage, but certainly the difficulty in removing the battery would greatly facilitate such illicit actions, as we move forward I advise as many people as possible to use open-source systems like Linux, OpenBSD etc.. and also avoid systems like Windows which does not even have a great reputation in terms of security (just search the internet for NSA backdoor, wannacry etc..).
