Other Bluetooth LE devices like an AirTag can last beyond one year on a CR2032 battery, so consuming about 2 milli-watt-hours (mWh) per day. An iPhone has at least 10 000 mWh battery capacity (depends on model), so in 1 month something like this consumes around 0.6 percentage points of battery.

I would think the normal drain of a battery sitting on the shelf is more than this feature uses.

Exactly, this is pretty much the case.

The weirdest thing is that Apple can do this and not use it to make wake up alarms go off after the device is shut down lol

I remembered that some old functional phone has such compatibility. Their alarm will ring no matter your phone is off or on. Being totally independent to the phone function.

I like a lot apple products and how they achieved popularizing many technologies, being the next one LIDAR but, for the first time ever I feel this is just going way too far. Sure I want to find my stolen phone even when it is off, but it is way too much loss of freedom having a permanent personal tracker even when the phone is off…

The Find My network is designed so that only you can track your own devices using it, nobody else can.

Neither hackers and the NSA right?

It literally tells you about this right next to the slider to turn off. If you tap the message it lets you turn it off. I see absolutely no issues with this.

Sure it won’t be like the Webcams that were possible to spy on, in spite of being turned off?

> A car battery should be swappable in a day or two Nio currently swaps out their car batteries in about 3 minutes, much like you'd get an oil change at Jiffy Lube or something. It's completely automated except someone pulls the car in/out of the bay for you. I imagine that human step will be relatively short lived. > they have to be heavily shielded in case of an accident. Yes, it's just a simple matter of purposefu…

And how many people drive more than 300km per day AND don't have the time to wait 50 minutes, but only got 5? The replaceable car batteries is technically possible (heck, everything is possible with engineering), but totally useless.

So it's possible and you reply to a person telling you about a legitimate usecase but you continue to go on about how it is totally useless?

Then just turn it off in Settings.

I remember a hack for Webcams that in spite of being turned off a malicious attack handled to spy on the user.

Which is why his twitter thing felt so odd and uncharacteristic especially coming from a professor of cryptography nonetheless. AOP has been around for years. If he's made the concession to use an iPhone because that's where people are, why freak out about some new feature like you were born yesterday? This is Apple, you know they don't document shit. Go look at core crypto... it's doc-gen function signatures and str…

I totally agree this totally feels like someone making noise to get attention even though the subject is closer to a mole hill approaches mountain in stature. I just think the attack "smart guy" for using iOS/Android meme is lame.

I mean I advocate for open systems that can be audited and verified and I still use an iPhone as a daily too although I've been exploring the pinephone on my other sim. I get it. That wasn't my intention to attack the smart guy for using an iPhone. More just like "what do you expect"?

If you don't trust the software to do what it says, then none of this matters anyway since they could have added this in silently ages ago or they could push custom firmwares out to targeted individuals to do it. Everything is based on the trust of the OS and hardware so it's not a useful point to make.

Software, sure, but up until this I could at least trust that if I turn my iPhone off it's not spying on me. Now I don't even have that. It's amazing the people _on this site_ in particular don't see a problem with this, and think it won't be abused by three letter agencies and their foreign counterparts.

You thought you could trust that if you turn your iPhone off it’s not spying on you.

In reality a software update was all that was required to enable this tracking.
