Can iPhone update iOS by itself?

Question

iPhone

Hi
I have iOS 6.1.3 and I don't want to part with it
. He downloaded the update to 8.4.1 without my knowledge, but can the iPhone update itself to 8.4.1? Or should I confirm?

Answer 1

Himself can not, will persistently offer.

Answer 2

It will only update when someone enters a 4-digit password. If you didn't do it, look for someone who knows your password ;)
After entering the password, the phone may not update immediately, Apple has a delayed update between 02:00 and 04:00 in the morning
