Spirits can wake iPads up

See this video. iPad isn’t connected to WiFi, so your hacker theory is wrong.

That’s the old iPad.

Except, the reminder could have woke it up. Reminder is for 10 PM I think. Perhaps reminding me about the reminder.

No worries, I turned WiFi on, and logged out of my Apple ID. Which deleted all reminders. I did disable WiFi again. But I should just reset it. Not sure you can use it without signing into an Apple ID though. You’d have to set it up, then logout of the Apple ID. Or leave it not setup. It can still be woke up in the setup screen. Not sure they can use it, perhaps they can bypass the setup screen for me.
