Apple's not the only one to do this, though. My Samsung S5 Active kept updating itself at night. I use it as my alarm, too, so this stupid "security feature" has made me late for work twice now (my phone is encrypted and asks for password on reboot). I finally figured how to disable the update app using ADB after the last time; my wife may not have that option without a jailbreak. Automatic updates that require a reboot are plain anti-consumer and unacceptable.
