> Could it be made to persist? I don't think persistence is necessary. How often do people actually power off their smartphone? What most people think of as the "power button" only locks the screen (and puts the CPU into a "suspend" state to save power). Most people would have an "uptime" of months on their smartphone.

If you’re in the Beta program, you might get a new OS point-release installed (thus restarting your phone) every few days at some points (such as at new-major-release RC time.)

How often do people actually power off their smartphone? If you have iOS with auto-updates on, then it can reboot several times a year when Apple releases point updates. Or at least once a year when the new big version of iOS comes out. (Unless I'm mistaken and iPhones no longer reboot on point updates anymore, but I'm pretty sure they still do.)

  Not an issue because the attacker can disable these updates.

I know, N=1 but I turn off my phone completely every night.

    - Part out of habit (since way before 'Do not disturb' mode), I want no disturbances when I sleep. - Because it saves battery/energy - No connected device in the bedroom (OK, I got a Kindle) - I (honestly) don't see any sense in having my phone run for ~7 hours while I'm asleep Why do you not turn off yours?

      the obvious reasons would be, to be reachable in case of emergency and as an alarm clock.

        Sure, that makes sense. I hope my peers don’t call me, but emergency services if something bad happens. And my immediate family is at home with me. And I have an alarm clock on the bedside table ;)

      On new devices it hardly saves any battery because iOS (or maybe just the latest iPhones) have become wickedly good about preserving battery when idle.

        Sure, but I’m a) still really happy with my iPhone SE and b) think it’s unnecessary to leave it in while sleeping.
