Agreed. Of all the messiness in iOS's settings app, it's honestly pretty easy to find the setting to turn this off (iCloud > Find My > Find My network). The Twitter thread almost reads like someone who's trying to not understand what's happening. Not to mention the fact that there's a reminder of this setting every time you turn your phone off, which can be tapped to disable this behavior.

The setting to tell my phone to turn all the way off when I turn it off is in under "iCloud" settings and is called "Find my network", and that's considered "pretty easy to find"?

No, the giant dialogue that appears when you turn off the phone, and tells you how to disable the feature is pretty easy to find.

What did the parent poster mean when he said "it's honestly pretty easy to find the setting to turn this off (iCloud > Find My > Find My network)"? Or are you disagreeing with him that it's "pretty easy to find" in the settings?

The "slide to power off" prompt literally says "iPhone Findable after Power Off >" right under it every time, but 99% of users will never see it or care about this feature because no one ever turns their phone off. But if you're one of those few people who does turn the phone off, it says right there, and you can tap on it to shut down to unfindable state this time instead. Note that it requires a passcode to disable…

I turn off my phone but never that way. It either runs out of power or I hard reset it. Either way I don't want it spying on me.

> Either way I don't want it spying on me.

then turn it off? most people will want this, and for those who don't it's easy to turn off.

Mine has no such message, and I'm on iOS 15. I just tested it. Any idea why?

I don’t think all devices support it. My iPhone XS doesn’t show the message, and under the find my toggle it says “Participating in the Find My network let’s you locate your phone even when it’s offline”, rather than when it’s off.

Not exactly new. The old BlackBerries allows you to "turn off" the device and have the alarm wake you up. It basically drops into a low power mode. It was easy to make a phone dead. You yanked out the batteries.

This is a feature of any device with a battery-backed real time clock (RTC). All x86 machines have this feature.

Pretty much anything with a clock that doesn't need resetting every time you turn it on can do this. An RTC chip is just a super low-power counter, and it costs almost nothing to toss in a wake-time comparator, so all of them do. When you set the wake-time alarm the host CPU really does power down 100% -- right after it sets the RTC chip's wake-time registers.

This is a long, long, long way from a microcontroller. It's not Turing-complete and has only a few dozen bits of storage for the counter. They're also manufactured on incredibly ancient fabrication processes (like 350nm until very recently) for lowest possible leakage.

If someone steals your phone all they have to do so you won't find it is to wrap it in aluminium foil.

and keep it wrapped till they get to their hideout which is in a faraday cage and then proceed to wipe it and bypass the activation lock.

it's another hassel for thieves which imho is a good thing. Might as well argue "why lock you door when all someone needs is a bump key!"

It doesn't connect to your iPhone's hot spot, but your daily iPhone is able to detect the other iPhone's presence just like it detects AirTags and logs that info.

Yes but apparently other iPhones can also detect it and send the location just like with the AirTag even if the iPhone is turned off. That was a surprise.

Was the phone actually off or just missing a SIM card?

Settings -> (Your Name/Apple ID ...) -> Find My -> Find My iPhone -> Find My Network in latest iOS.

Does 5 levels deep count as easy to find?

It's only supported on iPhone 11, 12, and 13 series.

To use this feature, you have to turn on Find My Network in settings (it is on by default), turning it on also means the device will report other nearby Find My devices like AirTags. I like to have my phone findable after power off, but I am still not sure whether I want my phone to report other devices.

Out of interest, what’s your concern with your phone reporting the location of other devices?
