It can be used, even while powered off, to track and surveil you.

How? The only legit thing I can think of is if they are tracking you anyway, and then they see your phone is turned off, they might try to claim that you must be up to something. But they won’t be able to track it while it’s off.

If you can’t take out the battery, it’s never actually off.

That’s not quite how it works, though. These devices are basically mini computers now, there’s a limit to what they can do without fully booting. Devices that are plugged into the wall might be likely to retain some power-draining function while plugged in, but there’s only so much you can do on a trickle charge while a phone is powered off.

They’re still running in low power mode and can wakeup from the network so they can absolutelly be made to “boot up” without turning the screen on and you being aware of it.

This is not like a bloody PC were the lights turn on and you can hear the fans when the thing starts, it’s a machine with a low power mode in which it can already do a lot and which can be brought to a high power mode if needed without there being any visible or audible side-effects to alert the user.

Unless you completelly cut it off from power (by taking the battery out, which you can’t in most modern smartphones) that smartphone with the lights off, the screen off and making no sound at all can just as easilly be in low power mode waiting for you to press the On button, as it can be in full power mode with a mobile network connection active, accessing the microphone and the GPS microchip and sending that data out, and both will look exactly the same from the outside.

let’s put aside everything @Aceticon@lemmy.world wrote you; if the French state was trying to legalize exactly this, it must be possible: la validation pure et simple de l’activation à distance des fonctions de géolocalisation de téléphone et autres objets connectés (voiture, balises airtag, montre etc) qui repose exactement sur le même procédé technique que le dispositif censuré : la compromission d’un périphérique, en y accédant directement ou par l’intermédiaire d’un logiciel espion pour en prendre le contrôle à distance.

wasn’t the scandal about the Pegasus spyware all about this imperceptibility?

Nothing in your links above indicate that the spyware operates while the phones are powered off (although I relied on a crappy translation of the French). Could spyware mock the shutdown process so that it looks like the phone is powered off while the phone is actually running? Sure it can, but the victim will be tipped off when the phone’s battery is being drained even while it is “shut off”. (And someone who is paranoid enough to shut down their phone would pay attention to that.) . It seems like it’s not worth the effort.

read, listen to people that were spied on using the pegasus software. Easy to find

i don’t know if you’ve met any real activists, militants in your life but they’re rarely geeks. And checking the battery of their phone or reading about battery life isn’t one of their priorities
