Qualification:

I've heard various rumors, some of which seem to be true, such as that the phone works even when it's turned off and maybe records all the time you're talking, and with neural networks you can find out what you said, even if you were ten meters away from the phone and in another room, you can use the neural network to improve the sound quality and still know What did you say.

There is also information that the phone can see through objects, so gluing something to the camera will not help.

I don't know what to do, I'm scared. Do you have any ideas on how to save myself from this if I live in the city and use my smartphone?

Apple Watch specifically has a mode for when it’s turned off that shows you the time when you tap the screen

There’s a general thing throughout tech where off isn’t off. This is one of those cases where “off” is just a low power mode, but you can still turn it off for real. This is not specific to Apple Watch at all.

There’s some grains of truth in the rant

too many devices don’t turn off by default
voice assistants listen to everything by default and are very good at picking out voices
and yes there was research that with a special setup researches were able to use WiFi to “see” through walls

But you can turn off always listening or otherwise remove voice assistants from your life. You can turn off devices. And you can gain perspective that researchers doing something clever doesn’t necessarily translate to every device doing it.

Be more afraid of the personal data you’re “willingly” giving away. From profiles to location to listening/watching reading content and times to opinions and associations
