> I’ll be pretty shocked if I’m “spied on” with this style of device. Why? There's plenty of devices in the wild constantly looking for wifi connection attempts, BLE Scans. Even cellular provider track locations in real-time by logging what cell towers you're using and associated signal strength. Just search for a place in google maps, and note the "Popular Times". How do you think they got that data :D

Um they get that data from being a monopoly and knowing when most people are looking up directions to or information about a location. Sure, they might do some other stuff to expand the data but there's much more relevant data right in their first-party domain.

No, they definitely read your location on your phone and "place you there". It has nothing to do with active actions made by yourself.

The same way traffic readings are done, not by cars, but by people in cars with phones.

So this is why the government will never force Apple to have easy to remove batteries.

Why would they waste their time on Bluetooth tracking when your location pings cell towers and WiFi hotspots?

Perhaps because the bluetooth tracking is a lot more accurate. But since not even Apple can access the data (or so they claim), this shouldn’t be useful for surveillance.

It's also interesting that this low-power mode is sufficiently low power for Apple to be feel comfortable sipping battery power continually. Any guesses about how much power this mode actually uses?

the NFC chip probably uses a tab bit more power, but it also uses battery after your phone dies to allow you to continue to pay for transit. "power reserve is available for up to five hours when your iPhone needs to be charged".

Somehow those bumbling buffoons over on HN found my tweet and half of them LIKE this feature. WTF! They're even discussing this thread like they like to do.

Thanks. Genuinely gave me a laugh. I predict HN mods won't be so humorous about it though.

I have net lost some karma. Probably should have put it all in one post but I don't think it would have had the same effect. It so clearly is silly and unwanted when you do something like that on this forum, and that was the point.

If you know about it.

you have to opt in when setting up a new device, and I think when updating to the OS version that enabled it

It jumps off of general Find My functionality, so pretty much anyone that has BT enabled, and doesn't want their phone to be sellable when stolen, will act as a proxy node.

Exactly. All mass surveillance request go straight to Google thanks to their unencrypted location tracking.

Do not try and power off the device. That’s impossible. Instead... only try to realize the truth. The truth? There is no off. From the Matrix, or something.

Sure you can power off your device! Just take out the batt-- oh...

This is where a tin foil hat really comes in handy!

In some way this feature reminded me of Android's song detection functionality which is also on by default and is constantly listening in the background [1]. So now tech companies normalized that: - the mic is always on. - the phone is always on, even when it's off. (thanks to AOP) - devices are always online even when they are offline.(thanks to company-operated p2p networks like Find My or Sidewalk) What could poss…

Yes which supports all kinds of functionality that people like. Just because you have a processor on or mic listening for wake words doesn’t mean everything is always being transmitted or evil is being done. State actors could do this selectively regardless even before these features. There have been attacks on Motorola razrs, etc for spying. Long before the smartphone, they just implanted microphones, shine lasers o…

No, but it means that I’m losing agency in whether or not those things can happen. That’s not ok and not benign.

So according to the post iphones now have an AOP (Always on Processor) running a proprietary operating system with access to other phone components. Do we know if other manufacturers also include such a processor? A quick google search showed a relevant apple patent [0] and a similar qualcomm processor product for wearables [1] which suggests to me this (always on processors on consumer electronics) "is out there ...…
