If this is indeed a security feature I'm about to buy my first iPhone.
CalyxOS and GrapheneOS have this as a feature.
Wouldn't this make your phone reboot all night while you're sleeping?
Just set the time too longer than you would be asleep. So in this screenshot above you could set it to 18 hours and most people at least that I know do not go 18 hours without unlocking their phone at least one time which would then reset the timer.
Yes. Alternatively, you can just.. power it off.
I keep mine on in case of family emergencies, it's also my alarm clock

Presumably it doesn't reboot unless it was already unlocked.
Two hours seems extremely low.
On grapheneos it's a setting, 18 hours by default I believe, but adjustable from 10 minutes to 72 hours.
That seems much more reasonable. Thanks for the info.
What is the good thing about a phone rebooting?
When you input your password, then your biometrics (faceID, fingerprint, etc) become active. A restart requires you to enter that again. The police can make you put your finger on your phone or look at it, but they can't make you divulge your password without a court order.
There are have also been some exploits that are possible ONLY while the machine is booted and already in that state unlocked state, rebooting relocks all the HW encryption and clears main memory.
Law enforcement have tools to bypass lockscreens and access the data on the device. They use backdoors and exploits, so older phones are more vulnerable. Most exploits only work if the phone has been unlocked at some point since it was booted.
This is why law enforcement keep them powered-on, and in a faraday cage. They are in a state with a better chance of unlock, but have no signal so nobody can remotely find/lock/wipe it.
Don't switch to a privacy-violating platform just for a feature found in open source operating systems.
Oh yeah, see they've done it perfectly by having it based on the last time you unlocked your screen.
This makes me even more interested in getting a newer pixel with graphene on it. I had the Pixel 3a back in the day, but have been using other devices since then with lineage. But this right here may very well bring me back. The only thing they need to do is have it on by default and set it to like a long time frame like 24 or 36 hours.

It should be, but it appears to be a bug.
Which is really sad quite frankly and if they did add it as a feature it should have a cooldown period of like 48 hours where it reboots twice in that time frame just so that if a cop turned the setting off it would still not help them

Anything to make their job harder is perfectly okay by me. The only thing that would be needed would be for this to be a feature and to have a cool down period of like 48 hours where the phone would reboot twice in that time so that if it was held it would still reboot itself.
Edit: Even better idea. Turning off the feature requires a reboot.
Note to those wishing for such a function, it’s possible by creating an iOS Shortcut - New Shortcut > Shutdown > Change it to ‘Restart’.
From there, you create an automation in Shortcuts to run based on time, location, etc.
Alas, it asks if you want to restart.
You could always take 10 seconds and invoke the operating system's hard shutdown command if you have the 10 seconds to spare. On Android at least, that's pressing and holding power and volume up for 10 seconds. But I do not know what it would be on the iPhone.
It would be best if the function was like if the phone has not been unlocked for at least 16 hours then reboot automatically. A time thing would be a problem though because then it would just reboot every day and that would be no fun.
I saw elsewhere this is a new feature in iOS 18.1, so it will probably pretty solid I’d think. But for shortcut wise, at minimum I suppose one could put automations that trigger when it detected within certain geofences or something… but then whenever you drive by your local police station it will kindly reboot your phone every time lol

this is the police we're talking about, they probably just forgot to charge them and are trying to shift the blame
Whatever it is, incompetence, bug, or feature, I love it.
Hot take: this is actually a bug not a feature.
Which is the saddest part, honestly. If it was a feature, that would be fantastic news. And especially if it had a cooldown feature of like 48 hours, where it would reboot twice in that timeframe, so that if a cop turned off the setting, while it was in their possession, it wouldn't matter because it would reboot anyway.
Someone said it in another thread yesterday, baseband memory leak. The firmware for that shit is terrible, I've had to deal with it in the past.
Apparently, there's at least a chance that it is an intentional feature instead of a bug. There's a comment link below somewhere in this thread that mentions it.

"new security feature" "warning"
🙂
I guess if you have the 10 seconds to do so, you could invoke the operating system hard reboot function, which at least on Android is pressing and holding power and volume up for 10 seconds. I don't know what it is on the iPhone.
Edit: Too bad there's not some sort of haptic to let you know that it accepted the command before it shuts down though.
Long press of power and volume up for a few seconds puts you into BFU.
Does it or does it just simply disable biometrics but leave it an AFU? I would hope that if it's going to disable the biometrics, that it would put it in BFU. But I do not know.
I don’t know how it works under the hood, but from a user perspective it behaves like it’s in BFU. Biometrics disabled, phone code required.
Yeah, don't get me wrong. Disabling the biometrics and requiring the pin is a good step. But I would like to see somebody test it to figure out whether it actually goes into BFU mode or not.
The police could just ask Apple, it isn't like they are going to have some secret reboot process that they would hide from the police.
And what would Apple be able to do about it? They don’t have your password*, so they’ll be just as unable to decrypt the device as the police.
*you can give them your password via iCloud I believe but you don’t have to
I'm not saying apple will do anything about it, just that they will let the cops know what is causing the reboots if asked.
